Genetic engineering transformed stem cells into working mini-livers that extended the life of mice with liver disease – The Conversation US

Takeaways

Scientists have made progress growing human liver in the lab.

The challenge has been to direct stems cells to grow into a mature, functioning adult organ.

This study shows that stem cells can be programmed, using genetic engineering, to grow from immature cells into mature tissue.

When a tiny lab-grown liver was transplanted into mice with liver disease, it extended the lives of the sick animals.

Imagine if researchers could program stem cells, which have the potential to grow into all cell types in the body, so that they could generate an entire human organ. This would allow scientists to manufacture tissues for testing drugs and reduce the demand for transplant organs by having new ones grown directly from a patients cells.

Im a researcher working in this new field called synthetic biology focused on creating new biological parts and redesigning existing biological systems. In a new paper, my colleagues and I showed progress in one of the key challenges with lab-grown organs figuring out the genes necessary to produce the variety of mature cells needed to construct a functioning liver.

Induced pluripotent stem cells, a subgroup of stem cells, are capable of producing cells that can build entire organs in the human body. But they can do this job only if they receive the right quantity of growth signals at the right time from their environment. If this happens, they eventually give rise to different cell types that can assemble and mature in the form of human organs and tissues.

The tissues researchers generate from pluripotent stem cells can provide a unique source for personalized medicine from transplantation to novel drug discovery.

But unfortunately, synthetic tissues from stem cells are not always suitable for transplant or drug testing because they contain unwanted cells from other tissues, or lack the tissue maturity and a complete network of blood vessels necessary for bringing oxygen and nutrients needed to nurture an organ. That is why having a framework to assess whether these lab-grown cells and tissues are doing their job, and how to make them more like human organs, is critical.

Inspired by this challenge, I was determined to establish a synthetic biology method to read and write, or program, tissue development. I am trying to do this using the genetic language of stem cells, similar to what is used by nature to form human organs.

I am a researcher specializing in synthetic biology and biological engineering at the Pittsburgh Liver Research Center and McGowan Institute for Regenerative Medicine, where the goals are to use engineering approaches to analyze and build novel biological systems and solve human health problems. My lab combines synthetic biology and regenerative medicine in a new field that strives to replace, regrow or repair diseased organs or tissues.

I chose to focus on growing new human livers because this organ is vital for controlling most levels of chemicals like proteins or sugar in the blood. The liver also breaks down harmful chemicals and metabolizes many drugs in our body. But the liver tissue is also vulnerable and can be damaged and destroyed by many diseases, such as hepatitis or fatty liver disease. There is a shortage of donor organs, which limits liver transplantation.

To make synthetic organs and tissues, scientists need to be able to control stem cells so that they can form into different types of cells, such as liver cells and blood vessel cells. The goal is to mature these stem cells into miniorgans, or organoids, containing blood vessels and the correct adult cell types that would be found in a natural organ.

One way to orchestrate maturation of synthetic tissues is to determine the list of genes needed to induce a group of stem cells to grow, mature and evolve into a complete and functioning organ. To derive this list I worked with Patrick Cahan and Samira Kiani to first use computational analysis to identify genes involved in transforming a group of stem cells into a mature functioning liver. Then our team led by two of my students Jeremy Velazquez and Ryan LeGraw used genetic engineering to alter specific genes we had identified and used them to help build and mature human liver tissues from stem cells.

The tissue is grown from a layer of genetically engineered stem cells in a petri dish. The function of genetic programs together with nutrients is to orchestrate formation of liver organoids over the course of 15 to 17 days.

I and my colleagues first compared the active genes in fetal liver organoids we had grown in the lab with those in adult human livers using a computational analysis to get a list of genes needed for driving fetal liver organoids to mature into adult organs.

We then used genetic engineering to tweak genes and the resulting proteins that the stem cells needed to mature further toward an adult liver. In the course of about 17 days we generated tiny several millimeters in width but more mature liver tissues with a range of cells typically found in livers in the third trimester of human pregnancies.

Like a mature human liver, these synthetic livers were able to store, synthesize and metabolize nutrients. Though our lab-grown livers were small, we are hopeful that we can scale them up in the future. While they share many similar features with adult livers, they arent perfect and our team still has work to do. For example, we still need to improve the capacity of the liver tissue to metabolize a variety of drugs. We also need to make it safer and more efficacious for eventual application in humans.

Our study demonstrates the ability of these lab livers to mature and develop a functional network of blood vessels in just two and a half weeks. We believe this approach can pave the path for the manufacture of other organs with vasculature via genetic programming.

The liver organoids provide several key features of an adult human liver such as production of key blood proteins and regulation of bile a chemical important for digestion of food.

When we implanted the lab-grown liver tissues into mice suffering from liver disease, it increased the life span. We named our organoids designer organoids, as they are generated via a genetic design.

Hadassah Medical Center and Neurogenesis Announce Groundbreaking Results from a Phase 2 Study in Progressive Multiple Sclerosis treated with NG-01…

JERUSALEM, Dec. 8, 2020 /PRNewswire/ --NeuroGenesis, a clinical-stage biopharmaceutical company advancing innovative cell therapies to combat myelin-related neurodegenerative diseases, and Hadassah Medical Center announced today highly positive results from a placebo-controlled Phase 2 clinical trial, headed by Prof. Dimitrios Karussis, together with Dr. Petrou Panayiota and Dr. Ibrahim Kassis from Hadassah Medical Center in Jerusalem, assessing the impact of NG-01 autologous proprietary subpopulation of mesenchymal stem cells (MSCs) on patients with progressive multiple sclerosis (MS).

The results, recently published in Brain, a prestigious peer-reviewed journal published by Oxford University, and highlighted in the "Editor's Choice", show that:

"The treatment was well tolerated and the trial met all of its primary endpoints," said Professor Dimitrios Karussis, lead principle investigator and Director of MS Center at Hadassah Medical Center, Jerusalem. "The patients' improvement was in many cases quite remarkable and included regain of motor function and noticeable effects on their cognitive abilities."

Prof Karussis added, "Although we currently have several good treatment options for relapsing remitting MS, we fall short in providing effective treatment for progressive MS that could substantially suppress the progression of disability. This trial provides encouraging results and suggests a potential for a new approach that may not only slow down the progression of the disease but even induce improvement and promote repair mechanisms in progressive MS."

The technology is now further developed by NeuroGenesis, following a license from Hadasit, Hadassah Medical Center Technology Transfer Company.

Neurogenesis' technology entails collecting bone marrow from the patient. Then by utilizing a proprietary process, a unique subpopulation of bone marrow cells is identified, cultured and enhanced towards remyelinating biofactory cells (NG-01) that also possess neurotrophic immunolatory and neuroprotective properties. The NG-01 cell population is injected directly into the central nervoussystem (through the cerebrospinal fluid), where the cells home-in on the damaged area, take up residence and produce significant amounts of neurotrophic factors.

"Progressive MS is a chronic, debilitating disease with no satisfactory treatment to improve or reverse established disability," said Tal Gilat, CEO of NeuroGenesis. "We are therefore extremely pleased to witness the significant positive effect of our NG-01 cells. Following recent interactions with the FDA, we look forward to confirming and expanding these findings in a large multi-center MS trial, and continuing advanced studies in additional indications such as ALS."

About the Phase 2 trial of NG-01

The Phase 2, randomized, double-blind, placebo-controlled, clinical trial assessed the safety, tolerability and efficacy of transplantation of NG-01 in people with progressive MS. The study enrolled 48 participants with progressive MS which were randomized into 3 groups, receiving either an intrathecal or intravenous NG-01 injection, or a placebo injection.

The two predetermined primary endpoints of the trial were: (i) the safety of the intrathecal and intravenous NG-01 treatments assessed by incidence of adverse events versus those in the placebo-treated group; and (ii) the differences among the three groups in the Expanded Disability StatusScale(EDSS) score changes and the proportion of patients with treatment failure, as evidenced by an increase in EDSS (disease progression) score, at 6 and 12 months. Overall, the study duration was 14 months.

About Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune disease that causes damage in the myelin and the nerve cells of the central nervous system (demyelinating plaques in brain and spinal cord), resulting in cumulating neurological disability. The destruction of the myelin (the covering that protects nerves and promotes the efficient transmission of nerve impulses) causes secondary damage to the nerve cells and progressive atrophy. MS often causes sensory disturbances in the limbs, including a prickling or tingling sensation (paresthesia), numbness, pain, and itching. Motor problems are common in people with MS. Affected individuals may have tremors, muscle stiffness (spasticity), exaggerated reflexes (hyperreflexia), weakness or paralysis of the muscles of the limbs, difficulty in walking, and poor sphincter control. The condition is also associated with visual problems, such as blurred or double vision or partial or complete vision loss. There is no known cure for multiple sclerosis.The existing treatments are mostly aimed to reduce the incidence of relapses of the disease and slow down the rate of neurological deterioration.

About NeuroGenesis

Neurogenesis is developing cell therapy for neurodegenerative diseases based on a unique approach for sustained delivery of high levels of remyelinating growth factors using the patient's own stem cells. The technology for this unique approach was licensed from Hadasit, theTechnology TransferCompany of Hadassah Medical Organization in Jerusalem, Israel. The Company's lead product is NG-01 for the treatment of progressive Multiple Sclerosis, (in which a placebo-controlled Phase 2 study has been completed and recently published). NG-01 were also tested in two successful Phase 2a trials in ALS patients. Up to today, more than 150 progressive MS and ALS patients from around the world have been treated with Neurogenesis'products via clinical trials (Phase 1 and Phase 2) and compassionate use treatments.

Treatment with Investigational LentiGlobin Gene Therapy for Sickle Cell Disease (bb1111) Results in Complete Elimination of SCD-Related Severe…

CAMBRIDGE, Mass.--(BUSINESS WIRE)--bluebird bio, Inc. (Nasdaq: BLUE) announced that new data from Group C of its ongoing Phase 1/2 HGB-206 study of investigational LentiGlobin gene therapy (bb1111) for adult and adolescent patients with sickle cell disease (SCD) show a complete elimination of severe VOEs and VOEs between six and 24 months of follow-up. These data are being presented at the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, taking place virtually from December 5-8, 2020.

Now with more than two years of data, we continue to observe promising results in our studies of LentiGlobin for SCD that further illustrate its potential to eliminate the symptoms and devastating complications of sickle cell disease. Consistently achieving the complete resolution of severe vaso-occlusive events (VOEs) and VOEs between Month 6 and Month 24 follow-up is unprecedented other than with allogeneic stem cell transplantation. Importantly, our data show the potential for LentiGlobin for SCD to produce fundamentally disease-modifying effects with sustained pancellular distribution of gene therapy-derived anti-sickling HbAT87Q and improvement of key markers of hemolysis that approach normal levels, said David Davidson, M.D., chief medical officer, bluebird bio. In addition to these clinical outcomes, for the first time with a gene therapy we now have patient-reported outcomes through the validated PROMIS-57 tool, showing reduction in pain intensity at 12 months after treatment with LentiGlobin for SCD. These results provide insight into the potential real-life impact LentiGlobin for SCD may offer patients.

SCD is a serious, progressive and debilitating genetic disease. In the U.S., the median age of death for someone with sickle cell disease is 43 46 years. SCD is caused by a mutation in the -globin gene that leads to the production of abnormal sickle hemoglobin (HbS). HbS causes red blood cells to become sickled and fragile, resulting in chronic hemolytic anemia, vasculopathy and unpredictable, painful VOEs.

In the HGB-206 study of LentiGlobin for SCD, VOEs are defined as episodes of acute pain with no medically determined cause other than a vaso-occlusion, lasting more than two hours and severe enough to require care at a medical facility. This includes acute episodes of pain, acute chest syndrome (ACS), acute hepatic sequestration and acute splenic sequestration. A severe VOE requires a 24-hour hospital stay or emergency room visit or at least two visits to a hospital or emergency room over a 72-hour period, with both visits requiring intravenous treatment.

LentiGlobin for SCD was designed to add functional copies of a modified form of the -globin gene (A-T87Q-globin gene) into a patients own hematopoietic (blood) stem cells (HSCs). Once patients have the A-T87Q-globin gene, their red blood cells can produce anti-sickling hemoglobin (HbAT87Q) that decreases the proportion of HbS, with the goal of reducing sickled red blood cells, hemolysis and other complications.

As a hematologist, I regularly see the debilitating effects of pain events caused by sickle cell disease. Pain has an overwhelmingly negative impact on many facets of my patients lives and can lead to prolonged hospitalizations, said presenting study author Alexis A. Thompson, M.D., professor of pediatrics at Northwestern University Feinberg School of Medicine and head of hematology at Ann and Robert H. Lurie Childrens Hospital of Chicago. The results observed with LentiGlobin gene therapy for SCD include the complete elimination of severe vaso-occlusive pain episodes, which is certainly clinically meaningful, but also for the first time, we have documented patients reporting that they are experiencing improved quality of life. This degree of early clinical benefit is extraordinarily rewarding to observe as a provider."

As of the data cut-off date of August 20, 2020, a total of 44 patients have been treated with LentiGlobin for SCD in the HGB-205 (n=3) and HGB-206 (n=41) clinical studies. The HGB-206 total includes: Groups A (n=7), B (n=2) and C (n=32).

The 32 patients treated with LentiGlobin for SCD gene therapy in Group C of HGB-206 had up to 30.9 months of follow-up (median of 13.0; min-max: 1.1 30.9 months).

In patients with six or more months of follow-up whose hemoglobin fractions were available (n=22), median levels of gene therapy-derived anti-sickling hemoglobin, HbAT87Q, were maintained with HbAT87Q contributing at least 40% of total hemoglobin at Month 6. At last visit reported, total hemoglobin ranged from 9.6 15.1 g/dL and HbAT87Q levels ranged from 2.7 8.9 g/dL. At Month 6, the production of HbAT87Q was associated with a reduction in the proportion of HbS in total hemoglobin; median HbS was 50% and remained less than 60% at all follow-up timepoints. All patients in Group C were able to stop regular blood transfusions by three months post-treatment and remain off transfusions as of the data cut-off.

Nineteen patients treated in Group C had a history of severe VOEs, defined as at least four severe VOEs in the 24 months prior to informed consent (annualized rate of severe VOE min-max: 2.0 10.5 events) and at least six months follow-up after treatment with LentiGlobin for SCD. There have been no reports of severe VOEs in these Group C patients following treatment with LentiGlobin for SCD. In addition, all 19 patients had a complete resolution of VOEs after Month 6.

Hemolysis Markers

In SCD, red blood cells become sickled and fragile, rupturing more easily than healthy red blood cells. The breakdown of red blood cells, called hemolysis, occurs normally in the body. However, in sickle cell disease, hemolysis happens too quickly due to the fragility of the red blood cells, which results in hemolytic anemia.

Patients treated with LentiGlobin for SCD in Group C demonstrated near-normal levels in key markers of hemolysis, which are indicators of the health of red blood cells. Lab results assessing these indicators were available for the majority of the 25 patients with 6 months of follow-up.

The medians for reticulocyte counts (n=23), lactate dehydrogenase (LDH) levels (n=21) and total bilirubin (n=24) continued to improve compared to screening values and stabilized by Month 6. In patients with Month 24 data (n=7), these values approached the upper limit of normal by Month 24. These results continue to suggest that treatment with LentiGlobin for SCD may improve biological markers to near-normal levels for SCD.

Pancellularity

As previously reported, assays were developed by bluebird bio to enable the detection of HbAT87Q and HbS protein in individual red blood cells, as well as to assess if HbAT87Q was pancellular, or present throughout all of a patients red blood cells. In 25 patients with at least six months of follow-up, on average, more than 80% of red blood cells contained HbAT87Q, suggesting near-complete pancellularity of HbAT87Q distribution and with pancellularity further increasing over time.

HGB-206: Improvements in Health-Related Quality of Life

Health-related quality of life (HRQoL) findings in Group C patients treated with LentiGlobin for SCD in the HGB-206 study were generated using the Patient Reported Outcomes Measurement Information System 57 (PROMIS-57), a validated instrument in SCD.

Data assessing pain intensity experienced by nine Group C patients were analyzed according to baseline pain intensity scores relative to the general population normative value: 2.6 on a scale of 0-10, where 10 equals the most intense pain. Data were assessed at baseline, Month 6 and Month 12.

Of the five patients with baseline scores worse than the population normative value average, four demonstrated clinically meaningful reductions in pain intensity at Month 12; the group had a mean score of 6.0 at baseline and a mean score of 2.4 at Month 12. Of the four patients with better than or near population normative values at baseline, two reported improvement and two remained stable with a mean score of 2.3 at baseline and 0.8 at Month 12.

HGB-206: Group C Safety Results

As of August 20, 2020, the safety data from Group C patients in HGB-206 remain generally consistent with the known side effects of hematopoietic stem cell collection and myeloablative single-agent busulfan conditioning, as well as underlying SCD. One non-serious, Grade 2 adverse event (AE) of febrile neutropenia was considered related to LentiGlobin for SCD. There were no serious AEs related to LentiGlobin for SCD.

One patient with significant baseline SCD-related and cardiopulmonary disease died 20 months post-treatment; the treating physician and an independent monitoring committee agreed his death was unlikely related to LentiGlobin for SCD and that SCD-related cardiac and pulmonary disease contributed.

New DARZALEX (daratumumab) Data from GRIFFIN Study Show Deeper and Longer Responses in Patients with Newly Diagnosed Multiple Myeloma – BioSpace

HORSHAM, Pa., Dec. 7, 2020 /PRNewswire/ --The Janssen Pharmaceutical Inc. Companies of Johnson & Johnson announced new data from the randomized Phase 2 GRIFFIN study showing that the addition of DARZALEX (daratumumab) to lenalidomide (Revlimid), bortezomib (VELCADE) and dexamethasone (D-RVd), followed by DARZALEXplus lenalidomide (D-R) maintenance therapy, resulted in deeper and improved responses, including minimal residual disease (MRD) negativity, compared to RVd followed by R alone in newly diagnosed, stem cell transplant-eligible patients with multiple myeloma.1These data investigating the use of DARZALEX in combination with RVd, which were shared in separate oral and poster presentations at the American Society of Hematology (ASH) 2020 Annual Meeting, provide further evidence that this regimen may provide greater efficacy for transplant-eligible, newly diagnosed multiple myeloma(NDMM) than standard therapy. The oral presentation (Abstract #549) shared longer-term follow-up data, and the poster presentation (Abstract #3243) featured additional data from the safety run-in cohort.1,2

"The long-term GRIFFIN data show that maintenance therapy with DARZALEX in combination with lenalidomide (D-R) resulted in deeper responses compared to R alone in patients with multiple myeloma who are newly diagnosed and transplant-eligible," said Peter Voorhees, M.D., Atrium Health's Levine Cancer Institute and GRIFFIN study investigator. "These data indicate that the addition of DARZALEX to RVd followed by R maintenance results in improved response rates and depth of response during induction, consolidation and maintenance treatment cycles."

Key Findings from GRIFFIN (Abstract #549): The GRIFFIN oral presentation featured updated safety and efficacy data based onlonger follow-up for D-RVd and evaluated the potential role of D-R for maintenance therapy in patients with NDMM.1

Key Findings from GRIFFIN (Abstract #3243): The poster presentation shared final results of the safety run-in cohort (n=16 patients) from the GRIFFIN study. Theseadditional data showed that maintenance therapy with DARZALEX and lenalidomide (D-R) improved both the sCR rate and MRD negativity rate in patients with NDMMwho underwent D-RVd induction, autologous stem cell transplant (ASCT) and D-RVd consolidation. This deepening of responses was associated with durable remissions, and no new safety signals were observed with maintenance therapy.2

"We continue to be encouraged by the GRIFFIN data showing deeper and improved responses in patients with newly diagnosed, ASCT-eligible multiple myeloma," said Andree Amelsberg, M.D., MBA, Vice President, Oncology Medical Affairs, Janssen Scientific Affairs, LLC. "These data show promising results for patients with newly diagnosed multiple myeloma, and we remain committed to exploring the full potential of DARZALEX and DARZALEX FASPRO."

About the GRIFFIN Study4 The Phase 2 GRIFFIN (NCT02874742) study has enrolled and treated more than 200 adults ages 18-70 years with NDMM and who are eligible for high-dose therapy/ASCT.

In the safety run-in cohort, patients received 25 mg of lenalidomide orally on Days 1-14; 1.3 mg/m2 of bortezomib subcutaneously on Days 1, 4, 8 and 11; and 20 mg of dexamethasone on Days 1, 2, 8, 9, 15 and 16, every 21 days during the induction and consolidation phases (Cycles 1-6). DARZALEX 16 mg/kg IV was given on Days 1, 8 and 15 of Cycles 1-4 and on Day 1 of Cycles 5-6.

During maintenance phase (Cycles 7-32), patients received 10 mg daily of lenalidomide (15 mg beginning at Cycle 10 if tolerated) on Days 1-21 every 28 days and DARZALEX 16 mg/kg IV every 56 days; this was amended to every 28 days based upon emerging clinical pharmacokinetic data demonstrating improved target saturation with every-4-week maintenance dosing. Maintenance therapy with lenalidomide may be continued beyond Cycle 32 in both arms, per local standard of care.

In the subsequent randomized Phase 2 portion of the study, approximately 200 patients were randomized and received treatment with RVd, induction and consolidation, ASCT and maintenance therapy with lenalidomide; or DARZALEX and RVd, ASCT and maintenance therapy with DARZALEX and lenalidomide.

About DARZALEX Janssen is committed to exploring the potential of DARZALEX (daratumumab) for patients with multiple myeloma across the spectrum of the disease. DARZALEX has been approved in eight indications, three of which are in the frontline setting, including newly diagnosed patients who are transplant eligible and ineligible.

DARZALEX has become a backbone therapy in the treatment of multiple myeloma, having been used in the treatment of more than 150,000 patients worldwide and more than 68,000 patients in the U.S. alone since its U.S. FDA approval in 2015. DARZALEX is the first CD38-directed antibody approved globally to treat multiple myeloma.

CD38 is a surface protein that is present in high numbers on multiple myeloma cells, regardless of the stage of disease.3 DARZALEX binds to CD38 and inhibits tumor cell growth causing myeloma cell death.4 DARZALEX may also have an effect on normal cells.5 Data across eight Phase 3 clinical trials, in both the frontline and relapsed settings, have shown that DARZALEX-based regimens resulted in significant improvement in progression-free survival and/or overall survival.5,6,7,8,9,10,11,12

About Multiple Myeloma Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.13,14When damaged, these plasma cells rapidly spread and replace normal cells with tumors in the bone marrow. In 2020, it is estimated that more than 32,000 people will be diagnosed and close to 13,000 will die from the disease in the U.S.15 While some patients with multiple myeloma have no symptoms, most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, kidney problems or infections.15

DARZALEXINDICATIONS

DARZALEX(daratumumab) is indicated for the treatment of adult patients with multiple myeloma:

DARZALEXIMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

DARZALEX is contraindicated in patients with a history of severe hypersensitivity (eg, anaphylactic reactions) to daratumumab or any of the components of the formulation.

WARNINGS AND PRECAUTIONS

Infusion-Related Reactions

DARZALEX can cause severe and/or serious infusion-related reactions including anaphylactic reactions. In clinical trials (monotherapy and combination: N=2066), infusion-related reactions occurred in 37% of patients with the Week1 (16mg/kg) infusion, 2% with the Week2 infusion, and cumulatively 6% with subsequent infusions. Less than 1% of patients had a Grade3/4 infusion-related reaction at Week 2 or subsequent infusions. The median time to onset was 1.5hours (range: 0 to 73hours). Nearly all reactions occurred during infusion or within 4hours of completing DARZALEX. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, laryngeal edema, and pulmonary edema. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting, and nausea. Less common symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, and hypotension.

When DARZALEX dosing was interrupted in the setting of ASCT (CASSIOPEIA) for a median of 3.75months (range: 2.4 to 6.9months), upon re-initiation of DARZALEX, the incidence of infusion-related reactions was 11% for the first infusion following ASCT. Infusion-related reactions occurring at re-initiation of DARZALEX following ASCT were consistent in terms of symptoms and severity (Grade 3 or 4: <1%) with those reported in previous studies at Week 2 or subsequent infusions. In EQUULEUS, patients receiving combination treatment (n=97) were administered the first 16mg/kg dose at Week 1 split over two days, ie, 8mg/kg on Day1 and Day2, respectively. The incidence of any grade infusion-related reactions was 42%, with 36% of patients experiencing infusion-related reactions on Day1 of Week1, 4% on Day2 of Week1, and 8% with subsequent infusions.

Pre-medicate patients with antihistamines, antipyretics, and corticosteroids. Frequently monitor patients during the entire infusion. Interrupt DARZALEX infusion for reactions of any severity and institute medical management as needed. Permanently discontinue DARZALEX therapy if an anaphylactic reaction or life-threatening (Grade 4) reaction occurs and institute appropriate emergency care. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion.

To reduce the risk of delayed infusion-related reactions, administer oral corticosteroids to all patients following DARZALEX infusions. Patients with a history of chronic obstructive pulmonary disease may require additional post-infusion medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease.

Interference With Serological Testing

Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Indirect Coombs test). Daratumumab-mediated positive Indirect Antiglobulin Test may persist for up to 6months after the last daratumumab infusion. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient's serum. The determination of a patient's ABO and Rh blood type is not impacted. Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX. Type and screen patients prior to starting DARZALEX.

Neutropenia and Thrombocytopenia

DARZALEX may increase neutropenia and thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX until recovery of neutrophils or for recovery of platelets.

Interference With Determination of Complete Response

Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.

Embryo-Fetal Toxicity

Based on the mechanism of action, DARZALEX can cause fetal harm when administered to a pregnant woman. DARZALEX may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX and for 3 months after the last dose.

The combination of DARZALEX with lenalidomide, pomalidomide, or thalidomide is contraindicated in pregnant women, because lenalidomide, pomalidomide, and thalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, pomalidomide, or thalidomide prescribing information on use during pregnancy.

ADVERSE REACTIONS

The most frequently reported adverse reactions (incidence 20%) were: upper respiratory infection, neutropenia, infusionrelated reactions, thrombocytopenia, diarrhea, constipation, anemia, peripheral sensory neuropathy, fatigue, peripheral edema, nausea, cough, pyrexia, dyspnea, and asthenia. The most common hematologic laboratory abnormalities (40%) with DARZALEX are: neutropenia, lymphopenia, thrombocytopenia, leukopenia, and anemia.

DARZALEX FASPRO INDICATIONS DARZALEXFASPRO is indicated for the treatment of adult patients with multiple myeloma:

DARZALEX FASPROIMPORTANT SAFETY INFORMATION CONTRAINDICATIONS

DARZALEX FASPRO(daratumumab and hyaluronidase-fihi) is contraindicated in patients with a history of severe hypersensitivity to daratumumab, hyaluronidase or any of the components of the formulation.

WARNINGS AND PRECAUTIONS

Hypersensitivity and Other Administration Reactions

Both systemic administration-related reactions, including severe or life-threatening reactions, and local injection-site reactions can occur with DARZALEX FASPRO.

Systemic Reactions

In a pooled safety population of 490patients who received DARZALEX FASPROas monotherapy or in combination, 11% of patients experienced a systemic administration-related reaction (Grade 2: 3.9%, Grade 3: 1.4%). Systemic administration-related reactions occurred in 10% of patients with the first injection, 0.2% with the second injection, and cumulatively 0.8% with subsequent injections. The median time to onset was 3.7hours (range: 9minutes to 3.5days). Of the 84systemic administration-related reactions that occurred in 52patients, 73(87%) occurred on the day of DARZALEX FASPROadministration. Delayed systemic administration-related reactions have occurred in less than 1% of the patients.

Severe reactions included hypoxia, dyspnea, hypertension and tachycardia. Other signs and symptoms of systemic administration-related reactions may include respiratory symptoms, such as bronchospasm, nasal congestion, cough, throat irritation, allergic rhinitis, and wheezing, as well as anaphylactic reaction, pyrexia, chest pain, pruritis, chills, vomiting, nausea, and hypotension.

Pre-medicate patients with histamine-1 receptor antagonist, acetaminophen and corticosteroids. Monitor patients for systemic administration-related reactions, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) administration-related reactions, immediately and permanently discontinue DARZALEX FASPRO.Consider administering corticosteroids and other medications after the administration of DARZALEX FASPROdepending on dosing regimen and medical history to minimize the risk of delayed (defined as occurring the day after administration) systemic administration-related reactions.

Local Reactions

In this pooled safety population, injection-site reactions occurred in 8% of patients, including Grade2 reactions in 0.6%. The most frequent (>1%) injection-site reaction was injection site erythema. These local reactions occurred a median of 7minutes (range: 0minutes to 4.7days) after starting administration of DARZALEX FASPRO. Monitor for local reactions and consider symptomatic management.

Neutropenia Daratumumab may increase neutropenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX FASPROuntil recovery of neutrophils. In lower body weight patients receiving DARZALEX FASPROhigher rates of Grade 3-4 neutropenia were observed.

Thrombocytopenia Daratumumab may increase thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Consider withholding DARZALEX FASPROuntil recovery of platelets.

Embryo-Fetal Toxicity Based on the mechanism of action, DARZALEX FASPROcan cause fetal harm when administered to a pregnant woman. DARZALEX FASPROmay cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX FASPROand for 3months after the last dose.

The combination of DARZALEX FASPROwith lenalidomide is contraindicated in pregnant women, because lenalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide prescribing information on use during pregnancy.

Interference with Serological Testing Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6months after the last daratumumab administration. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient's serum. The determination of a patient's ABO and Rh blood type are not impacted.

Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX FASPRO.Type and screen patients prior to starting DARZALEX FASPRO.

Interference with Determination of Complete Response

Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some DARZALEX FASPROtreated patients with IgG kappa myeloma protein.

ADVERSE REACTIONS The most common adverse reaction (20%) with DARZALEX FASPROmonotherapy is: upper respiratory tract infection. The most common adverse reactions with combination therapy (20% for any combination) include fatigue, nausea, diarrhea, dyspnea, insomnia, pyrexia, cough, muscle spasms, back pain, vomiting, upper respiratory tract infection, peripheral sensory neuropathy, constipation, and pneumonia.

The most common hematology laboratory abnormalities (40%) with DARZALEX FASPROare decreased leukocytes, decreased lymphocytes, decreased neutrophils, decreased platelets, and decreased hemoglobin.

Anatomy of a vaccine: What it takes to create a safe, effective COVID shot – University of California

Shawn stepped into the UCLA Vine Street Clinic in Hollywood with confidence. He offered up his arm. The UCLA doctor injected him. It took seconds; there was barely a sting.

Twenty-four hours after the first of two shots, given 28 days apart, he suffered the headaches and fatigue associated with a milder case of COVID-19. But Shawn remained calm, resolved to honor the memory of his mother, a nurse who had died in May 2020 from an unrelated cause.

The 57-year-old nonprofit worker had been thinking about the challenges of COVID-19 for a long time, and he decided to go through the lengthy consent process for the medical trial. It gave me something to do with my anger that was so much better than yelling at someone for not wearing a mask, he says. And [at UCLA] I felt I was in good hands.

Shawn is one of many volunteers who have stepped up to participate in medical trials at UCLA, which is part of a global network thats determined to help find a vaccine against the novel coronavirus.

The stakes are huge. More than 250,000 Americans have already died, and there have been more than 1 million deaths around the world. Economies have been brought to their knees, social tensions have disrupted communities and emotional maladies are on the rise.

In response, doctors and scientists have been challenged to be resilient and ingenious. Theyre taking an array of different approaches, knowing that public confidence in vaccines hangs in the balance.

In addition, it has been a challenge to create a vaccine in such a short amount of time similar efforts have taken five to 10 years. Pharmaceutical giant Pfizer and biotech firm Moderna have both reported remarkable progress, announcing in November that their vaccine candidates were more than 90% effective. All of which has raised questions about the next steps, such as how the vaccines will be distributed.

I dont want to make a vaccine to protect against mild disease, says Dr. Marcus Horwitz, distinguished professor of medicine and microbiology, immunology and molecular genetics at the David Geffen School of Medicine at UCLA. I want to protect people who are going to get severe disease.

Horwitz has already developed vaccines against the bacteria behind tuberculosis, anthrax and the tick-borne disease tularemia, but he has never tried to create a vaccine against a virus. When faced with a worldwide pandemic, we thought we might be able to make a contribution, he says.

Vaccines work by training the immune system to recognize and fight disease-causing pathogens, such as viruses or bacteria. Doctors introduce the bodys immune system to antigens, which are molecules from the virus or bacteria, and the immune system responds by making proteins called antibodies and immunity-building T cells, which both neutralize the pathogen.

The delivery of these antigens requires a delicate calculus: It must provoke the immune system, but not go so far as to make the patient ill. You need a vector that will wake up the immune system of the host, but not cause any further harm, Horwitz says.

The vaccine approach by Horwitz and his team, including lead investigator Qingmei Jia, is a medical outlier: They adapted an existing antibacterial platform to build protection against SARS-CoV-2, the virus that causes COVID-19. The team has shown that their vaccine candidate protects hamsters, which develop severe disease in a way similar to humans.

Some of the potential vaccines for SARS-CoV-2 use a weakened form of an adenovirus, which causes the common cold, to deliver the S protein that is found on the surface of the SARS-CoV-2 virus. Horwitzs vaccine stands out from the pack because it uses a weakened bacterium to deliver two SARS-CoV-2 proteins, the M and N proteins.

That difference could have a tremendous impact. Billions of COVID-19 vaccine doses are needed, and bacteria, unlike viruses, are easy and cheap to produce and transportable.

The success of a COVID-19 vaccine also depends on the immune system, which can be less robust in older people.

This is a problem that has driven Song Li, chair of the bioengineering department at the UCLA Samueli School of Engineering, who has focused his career on cell and tissue engineering. Adapting a concept from cancer immunotherapy, Li is developing a biomaterial vaccine booster using artificial cells that could improve the immune systems ability to generate long-term protection.

When the immune system encounters a destructive pathogen, it produces cells that are designed to attack the invader. A small number of those cells, called T memory stem cells, can stay in the system for years ready for a future invasion. Unfortunately, our ability to produce T memory stem cells declines as we get older. Li hopes his booster, in combination with a vaccine, can help fragile immune systems effectively fight against the SARS-CoV-2 virus.

My goal at the outset was to help the elderly population, Li says. But it could be useful for any person whose immune system needs help generating protection from the virus.

Another UCLA team led by Bogdan Pasaniuc, Dr. Manish Butte and Dr. Daniel Geschwind, the Gordon and Virginia MacDonald Distinguished Professor of Human Genetics at the Geffen School of Medicine is trying to find out why the virus significantly impacts some, but leaves others relatively unscathed.

We know age is a major factor, but we see older people who get infected and do quite well, Geschwind says. We have a limited ability to predict how sick someone will get. His team hopes that studying whole-genome sequences from thousands of COVID-19 patients will reveal hidden factors that make some more vulnerable than others. The research could help identify people who are at higher risk for infection as well as develop new treatment and prevention strategies.

Dr. Brigitte Gomperts, professor of pediatrics and pulmonary medicine and a member of the UCLA Broad Stem Cell Research Center, is studying how COVID-19 affects lung tissue. By using stem cellderived clusters of lung cells, known as organoids, she can rapidly screen thousands of prospective treatments. Because the organoids are grown from human cells and reflect the cell types and architecture of the lungs, they can offer insights into how the virus infects and damages the organ.

At UCLA medical centers around Los Angeles County, physicians are ensuring that their medical trials include diverse groups of people and women of all ages.

COVID-19 has hit the African American and Latino communities particularly hard, says Dr. Jesse Clark, associate professor-in-residence in the department of medicine at the Geffen School of Medicine. We have to make sure that any vaccine has been determined to be safe and effective in all populations that will receive it.

Clark is medical director of the UCLA Vine Street Clinic, which is involved in the Moderna clinical trial. Notably, Modernas vaccine works differently from a typical vaccine, because it doesnt contain the virus at all. Instead, it uses messenger RNA, or mRNA, which uses the bodys genetic code to produce antibodies against the virus.

CNN mentioned that the vaccine trials were having trouble finding minorities to participate, says Roderick, a 37-year-old IT manager and father of two, who is participating in the Moderna trial. Being Black and Mexican, and knowing how hard my demographic has been hit, I just went ahead and signed up online. Its worth doing to help out.

Meanwhile, Dr. Katya Corado, an infectious disease specialist at Harbor-UCLA Medical Center in Torrance, has been enrolling patients in a phase 3 clinical trial of an adenovirus vector vaccine thats under development by the University of Oxford and the biopharmaceutical company AstraZeneca.

All vaccines undergo three phases of clinical trials, according to rules set by the Food and Drug Administration. Phase 1, which involves 20 to 100 volunteers, tests the safety and dosage of the vaccine. Phase 2 tests the drugs efficacy and side effects among several hundred participants, and phase 3 gathers more information about a vaccines safety and effectiveness by studying thousands of volunteers.

In the phase 3 trial, we focus on studying how effective the vaccine is in populations that need it most, Corado says.

Clark and Corado are both hopeful that their work can protect the most vulnerable, which includes people over 65, patients with chronic conditions, those facing economic disadvantages and essential workers.

Inoculations have eradicated past epidemics, such as smallpox. But public faith in vaccines has wavered, especially when a now-disproven report in 1998 suggested that the measles, mumps and rubella vaccine was linked to autism spectrum disorder. That has led to U.S. outbreaks of measles, which had been previously eliminated. So scientists recognize the importance of getting the COVID-19 vaccine right.

There are other factors to consider as well. Vaccine distribution will be high on the agenda of the incoming White House administration, but if supply is limited, the Centers for Disease Control and Prevention recommends prioritizing certain groups, such as medical workers.

Also, some vaccines currently in development need to be stored in ultra-cold conditions. For example, Pfizers vaccine must be stored at minus 70 degrees Celsius, while Modernas vaccine must be kept at minus 20 degrees Celsius the temperature of a regular freezer. These factors will affect how the vaccines are distributed.

Some lawmakers have advocated letting the virus run its course in the hopes of achieving herd immunity, which is when enough people have become immune to an infectious disease, either through being infected or vaccination. Since the COVID-19 vaccine is still pending, a majority of people will need to be infected in order to achieve herd immunity and that comes at a terrible cost.

According to Dr. Robert Kim-Farley, professor-in-residence of epidemiology at the UCLA Fielding School of Public Health, up to 2 million Americans would have to die before the country reached herd immunity.

He argues that vaccines work, even if they are not perfectly safe or perfectly effective, as proven by the near-eradication of polio. But approving vaccines prematurely to buckle under the pressure of politics or profit could cause a terrible backlash against being vaccinated, which could lead to future outbreaks.

We want to make sure we are not cutting corners, Kim-Farley says, that we are getting the best vaccine that has the highest efficacy, the longest duration, the fewest number of side effects [with] the fewest number of doses.

This is a very high-stakes game, and its important to get it right, without recalls or playing into the [anti-vaccination] narrative. What still concerns me is the equitable distribution of vaccines to make sure that countries that are not as wealthy as us have access to these life-saving vaccines. We are all members of one global community.

Development of New Stem Cell Type May Lead to Advances In Regenerative Medicine – Newswise

Newswise DALLAS Dec. 3, 2020 A team led by UT Southwestern has derived a new intermediate embryonic stem cell type from multiple species that can contribute to chimeras and create precursors to sperm and eggs in a culture dish.

The findings, published online this week in Cell Stem Cell, could lead to a host of advances in basic biology, regenerative medicine, and reproductive technology.

Cells in early embryos have a range of distinct pluripotency programs, all of which endow the cells to create various tissue types in the body, explains study leader Jun Wu, Ph.D., assistant professor of molecular biology. A wealth of previous research has focused on developing and characterizing nave embryonic stem cells (those about four days post-fertilization in mice) and primed epiblast stem cells (about seven days post-fertilization in mice, shortly after the embryo implants into the uterus).

However, says Wu, theres been little progress in deriving and characterizing pluripotent stem cells (PSCs) that exist between these two stages largely because researchers have not been able to develop a paradigm for maintaining cells in this intermediate state. Cells in this state have been thought to possess unique properties: the ability to contribute to intraspecies chimeras (organisms that contain a mix of cells from different individuals of the same species) or interspecies chimeras (organisms that contain a mix of cells from different species) and the ability to differentiate into primordial germ cells in culture, the precursors to sperm and eggs.

For this study, the researchers successfully created intermediate PSCs, which they named XPSCs from mice, horses, and humans.

Wu says that these results could eventually lead to an array of advances in both basic and applied research. For example, looking at gene activity in XPSCs from different species and interspecies chimeras could help researchers understand which signatures have been conserved through evolution. Examining the communication between cells in chimeras may help scientists identify strategies that could be used to accelerate the development of tissues and organs from stem cells used for transplantation. And using chimera-derived primordial germ cells to create sperm and eggs could aid in preserving endangered animal species and advancing infertility treatments.

These XPSCs have enormous potential. Our study helps open the door to each of these possibilities, says Wu, who is a Virginia Murchison Linthicum Scholar in Medical Research.

Wu notes that developing XPSCs presented a special challenge because the conditions that keep nave PSCs in a stable state are exactly the opposite from those that stabilize primed PSCs. While culture conditions for nave PSCs must activate a WNT cell-signaling pathway and suppress the FGF and TGF- pathways, the conditions to maintain primed PSCs must suppress WNT and activate FGF and TGF-.

Aiming for the preferred environment for XPSC derivation, Wu and his colleagues placed cells from early mouse embryos into cultures containing chemicals and growth factors that activate all three pathways. These lab-grown cells were extremely stable in culture and able to multiply without developing any further for approximately two years.

Additional experiments showed that these cells met the expectations researchers have long strived to meet of contributing to chimeras and directly differentiating into primordial germ cells. Wu and his colleagues made intraspecies chimeras of mice using cells derived from mice with different coat colors by injecting the cells into early mouse embryos. They also tracked the contributions of the XPSCs by tagging the cells with a fluorescent protein and then identifying them throughout the resulting offsprings body.

Wus team made interspecies chimeras by injecting horse XPSCs into early mouse embryos and allowing the embryos to develop in mice for several days. Surprisingly, although horses have a comparatively long gestational period nearly a year the researchers found that these foreign cells had contributed to mouse organ development, indicating that signals from the mouse cells determine organ developmental timelines.

Like XPSCs from other species, the human cells showed that they were capable of differentiating into a variety of tissues if culture conditions allowed them to progress in development, as well as directly form primordial germ cells in a dish.

Other UTSW researchers who contributed to this study include Leqian Yu, Yulei Wei, Carlos A. Pinzon Arteaga, Masahiro Sakurai, Daniel A. Schmitz, Canbin Zheng, and Emily D. Ballard. Yu and Wu are inventors on a patent application arising from this work.

This study was funded by the Cancer Prevention and Research Institute of Texas (CPRIT No. RR170076), the Hamon Center for Regenerative Science and Medicine, the Guangdong Provincial Key Laboratory of Genome Read and Write (No. 2017B030301011), and the Asahi Glass Foundation.

UCLA receives $7.3 million grant to build state-of-the-art facility for developing gene, cell therapies – UCLA Newsroom

UCLA Health

The new 13,000-square-foot facility will be located in UCLAs Center for the Health Sciences.

UCLA has received a $7.3 million grant from the National Institutes of Health to build a state-of-the-art facility in which to produce gene and cell therapies aimed at treating a host of illnesses and conditions.

The new 13,000-square-foot facility, to be constructed in UCLAs Center for the Health Sciences, will provide a highly regulated environment with features such as systems to manage air flow and filtering, laboratory spaces and bioreactors. The new facility is expected to be ready for use in 2023.

This grant provides critical funds to build a facility that will enable the development of a new generation of cellular therapies for cancer and other deadly diseases, said Dr. AntoniRibas, a UCLA professor of medicine and director of the Parker Institute for Cancer Immunotherapy Center at UCLA.

The new facility will be built according to U.S. Food and Drug Administrationgood manufacturing practices, a set of guidelines intended to ensure that facilities producing products for human use are built to maximize safety and effectiveness, and to reduce the risk for contamination.

It will replace a facility in UCLAs Factor Building that UCLA scientists currently use for similar research. But that space, which was put together by combining existing research laboratories, lacks the capacity to process certain cells and handle other bioengineered products, and it cannot accommodate the growing number of UCLA scientists pursuing research on gene and cell therapies, said Dr. Stephen Smale, vice dean for research at the David Geffen School of Medicine at UCLA and principal investigator of the NIH grant.

The new facility will be larger, so it will be able to support more projects simultaneously, and its design will allow a smooth flow of products into and out of the facility, Smale said. The larger number of rooms is really important because even when a single therapy is being tested, cells from each patient need to be processed in their own room.

Dr. Eric Esrailian, chief of theUCLA Vatche and Tamar Manoukian Division of Digestive Diseases, is helping to lead the expansion of UCLAs immunology and immunotherapy efforts. It will be a cornerstone for UCLAs commitments to building on existing strengths in the areas of immunology and immunotherapy and expanding toward the creation of a transformational institute in these fields, he said.

Despite the shortcomings of the current space, UCLA researchers have still produced groundbreaking work in it. These include tumor-targeting therapies developed by Ribas, Dr. Donald Kohn, Dr. Linda Liau, and other UCLA researchers.

Ribas, Kohn and Liau are also members of theUCLA Jonsson Comprehensive Cancer Centerand theUCLA Broad Stem Cell Research Center. Kohn is a distinguished professor of microbiology, immunology and molecular genetics and Liau is chair of UCLAs department of neurosurgery.

Kohn, who alsodeveloped a cure for bubble baby syndrome,said he will welcome the new facility because of its increased capacity for researchers to pursue treatments and cures that could significantly improve the health and quality of life of so many people. For instance, it will have the capacity to produce large batches of viral vectors microbes that make it possible to introduce potentially curative genes into cells for gene therapy studies.

This new facility will allow the innovative cell and gene therapies pioneered at UCLA to be available to a wider number of patients and accelerate the development of novel cures, said Kohn, whose work has also led to an experimental stem cell gene therapy for sickle cell disease that is showing promising early results in clinical trials.

Liau, a neuro-oncologist, said the new facility will enable researchers to create personalized vaccines and cell therapies for a much larger number of patients.

In the current facility, we are only able to enroll one patient at a time in our cell therapy trials, so many eligible patients have had to be turned away, Liau said.With greater capacity to manufacture gene and cell therapy products that meet FDA good manufacturing practice standards, this new UCLA facility will really allow us to further innovate and accelerate our translational research toward a cure for brain cancer.

Possible Role for Comprehensive Molecular ProfilingBased Treatment Selection in Newly Diagnosed AML, Study Suggests – Cancer Therapy Advisor

The feasibility of a precision medicinebased approach was demonstrated for patients with newly diagnosed acute myeloid leukemia (AML), according to findings from a phase 1/2 clinical trial reported in Nature Medicine.

The current standard of care for the treatment of patients diagnosed with AML involves prompt initiation of intensive induction chemotherapy, such as 7 days of standard-dose cytarabine and 3 days of daunorubicin, or administration of a hypomethylating agent for those deemed unable to tolerate standard induction therapy, to prevent rapid progression of disease in this predominantly older patient population.

Hence, time for comprehensive molecular characterization of the disease is not built into typical treatment protocols for patients with newly diagnosed AML. However, long-term outcomes of patients with newly diagnosed AML treated with intensive chemotherapy without autologous hematopoietic stem cell transplantation have been shown to be poor, and hypomethylating agents are not a curative approach in the setting of AML.

This nonrandomized, open-label, multicenter, umbrella protocol study sponsored by the Leukemia & Lymphoma Society (BEAT AML Master Trial; ClinicalTrials.gov Identifier: NCT03013998) enrolled adult patients with suspected AML prior to the administration of frontline treatment.

During a 7-day period prior to treatment assignment, bone marrow biopsy specimens of eligible patients were subjected to cytogenetic analysis, comprehensive molecular profiling using next-generation sequencing, and a FLT3-ITD ratio testing. On the basis of these results, patients with a dominant AML clone characterized by an actionable alteration were assigned to 1 of multiple molecularly defined substudy treatment arms, whereas those without evidence of such an alteration were assigned to the marker-negative subgroup.

In describing the purpose of this study, the investigators stated that they collaboratively implemented a new prospective clinical trial approach aimed at facilitating frontline treatment assignments to specific genomic-defined AML subtypes.

Of the 395 eligible patients, approximately 95% were assigned to treatment within 7 days of bone marrow biopsy collection. Of note, only 26 of these patients exhibited evidence of rapid disease progression necessitating initiation of therapy during the 7-day testing window.

The most common mutational drivers identified were DNMT3A (22.7%), TET2 (19.6%), TP53 (19.1%), ASXL1 (19.1%) and SRSF2 (18.4%).

Regarding molecularly based treatment assignment, the study authors commented that these data show that there were few co-occurring dominant mutations that could have been used for an alternative therapeutic assignment.

Only 224 (56.7%) of patients agreed to receive treatment according to their assigned BEAT AML substudy treatment arm, with 103, 28, and 38 patients selecting standard-of-care treatment, alternative investigational therapy, and palliative care, respectively.

Patients were encouraged to select an alternative therapy (alternative investigational therapy, [standard of care] or palliative care) if the patient with their health-care providers deemed this a better option, the study investigators noted.

A key finding from this study was the 30-day mortality of patients starting at initial study enrollment was 3.7% for patients enrolled on the BEAT AML trial protocol and 20.4% for those who choose to receive standard-of-care therapy.

Furthermore, rates of 1-year overall survival were 54.7%, 27.6%, 11%, and 57.4% for patients treated on the BEAT AML protocol, or with standard-of-care therapy, palliative care, and alternative investigational therapy, respectively.

However, the study investigators noted that while our study demonstrates the feasibility of precise molecular treatment assignment in older adults with AML, it does not clearly differentiate the benefit of treatment assignment based on a molecular target from better outcome that occurs simply from enrolling on a clinical trial.

They also emphasized that this approach requires a detailed team-coordinated effort by investigators, patients and caregivers, genomic laboratories, cytogenetic laboratories and a central treatment assignment team.

In their concluding remarks, the researchers commented that randomization of specific large genomic groups to targeted therapy versus [standard of care] or, in less common genomic groups, comparison of treatment with targeted therapy to either real-world data or synthetic controls, will be required to determine the comparative effectiveness of a precision medicine-based approach vs standard-of-care therapy in patients with newly diagnosed AML.
