Frequency Therapeutics to Present at the 14th Stem Cell Research … – Business Wire (press release)

WOBURN, Mass.--(BUSINESS WIRE)--Frequency Therapeutics, a company spearheading the movement to restore hearing by harnessing the regenerative potential of progenitor cells in the body, today announced that Chris Loose, Ph.D., the Companys Co-founder and Chief Scientific Officer, will be presenting at the 14th Stem Cell Research and Regenerative Medicine Conference. The presentation titled, Progenitor Cell Activation - an Enabling Technology for In-Situ Tissue Regeneration, will look to explore the companys proprietary Progenitor Cell Activation (PCA) platform, founded on recent discoveries in progenitor cell biology by Bob Langer, Sc.D. at MIT and Jeff Karp, Ph.D., at Harvard. PCA is leading to a new class of drugs that regenerate healthy tissue within the body. The presentation will take place on Wednesday, April 5 at 4:50 p.m. The conference is being held from April 5 to 6 in Boston, MA.

The biology, chemistry and regenerative properties behind our PCA platform is quite exciting and has the potential to yield a whole new category of disease-modifying therapeutics for a wide range of degenerative conditions, said Dr. Loose. Our lead program is focused on the over 360 million people worldwide who suffer from hearing impairment, with no effective therapeutic solutions currently available. By targeting cellular regeneration within the inner ear to restore healthy tissue and reverse hearing loss, we look to develop a direct therapeutic approach through a locally applied drug without the need for surgical interventions.

Chris has provided exceptional leadership in translating the vision of our founders, Bob Langer and Jeff Karp, into a successful product development organization, said David Lucchino, President, Co-founder and CEO of Frequency. This presentation exemplifies the core of the research and development Frequency is performing with our PCA platform, and addresses our intent of advancing a first-in-class therapeutic option for chronic hearing loss.

ABOUT PROGENITOR CELL ACTIVATION (PCA) Frequencys precise and controlled approach transiently causes Lgr5+ progenitor cells to divide and differentiate, much like what is seen in naturally regenerating tissues such as the skin and intestine. Frequency activates stemness through mimicking signals provided by neighboring cells (the stem cell niche) with small molecules, and this proprietary approach is known as the Progenitor Cell Activation (PCA) platform. Frequency believes that PCA has the potential to yield a whole new category of disease-modifying therapeutics for a wide range of degenerative conditions. To fuel its drug discovery programs, Frequency is leveraging a PCA screening platform using primary human cells, including cochlear progenitor cells and adult human progenitor cells from the GI tract. Frequencys initial focus is on chronic noise induced hearing loss. Other potential applications include skin disorders, gastrointestinal diseases, and diabetes.

ABOUT FREQUENCY THERAPEUTICS Frequency Therapeutics develops small molecule drugs that activate progenitor cells within the body to restore healthy tissue. Through the transitory activation of these progenitor cells, Frequency enables disease modification without the complexity of genetic engineering. Our lead program re-creates sensory cells in the inner ear to treat chronic noise induced hearing loss, which affects over 30 million people in the U.S. alone. http://www.frequencytx.com.

Stem Cell – Dr. Humeira Badsha Medical Center

What is so neat about PRP is how it works. Years ago, scientists unraveled some of the action mechanisms in the lab, and what was found is that the PDGF (platelet derived growth factor) activates pericytes. Later it was discovered that these pericytes were unactivated mesenchymal stem cells. Once these cells become activated, they act as general directors of healing and regeneration and release a myriad of cytokines and other factors that have trophic, anti-inflammatory, mitogenic, anti-scarring, and anti-infection attributes. In the case of the dental implants, osteoblasts were activated by the pericytes to realize improved bony in-growth of the implants. This action has been confirmed by laboratory investigations. In the case of osteoarthritis of the knee, the cartilage that is lost as an after-effect of the normal ageing process is not regrown but the environment is altered so that there is less pain, and less further loss of the knee cartilages. In many respects it alters the progression or worsening of the disease, and it is hoped by many that surgeries, such as knee replacements, are delayed or avoided all together. Today, PRP is used in many areas of medicine in the US and Europe for treating musculoskeletal problems, plastics, aesthetics, dermatology, general surgery, ENT, rheumatology, primary care, pain management, and physical medicine and rehabilitation. Negative side effects and complications are uncommon as with many current treatments and medications in use today.

Stem Cell Transplant Making Rapid Progress – Financial Tribune

Around 6,000 hematopoietic stem cell transplantations are carried out annually in Iran using the patients own cells, and a far higher number are performed using cells from donors who are often close relatives of the patient, according to the Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT) affiliated to the Tehran University of Medical Sciences. Ardeshir Qavamzadeh, head of the center, said the number of stem cell transplants is on par with developed countries. The success rate in the treatment of diseases requiring transplant is 67% at HORCSCT, ISNA quoted him as saying. Referring to the fast and progressive development of stem cell discipline in Iran, he said since 1983, when the adult leukemia specialty was initiated in the country, nearly 300 specialists have been trained in the field and there is at least one specialist in each province now. Today, one cannot find a treatment method of stem cell transplant in the worlds advanced research centers that is not available or practiced in Iran. We have reached a level where we can compete with the developed nations. HSCT Hubs There are 10 hubs for hematopoietic stem cell transplant (HSCT) in the country. Each includes medical universities from the provinces with one as the focal point. Medical universities of Zanjan, Qazvin, Alborz and Qom comprise one of the hubs with Zanjan as the center, said Mehdi Eskandari, education deputy at Zanjan University of Medical Sciences. HSCT is the transplantation of multi-potent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. It may be autologous (when the patients own stem cells are used) or allogeneic (stem cells from a donor). It is a medical procedure in the field of hematology, most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia. Since HSCT is a relatively risky procedure with many possible complications, it is reserved for patients with life-threatening diseases. However, as the survival rate following the procedure has increased, its use has expanded beyond cancer, including in autoimmune diseases, blood diseases like thalassaemia major, metabolic disorders, alcoholic liver, and even rheumatism.

Ovarian cancer: Effective immunotherapy steps closer with new T cell study – Medical News Today

At a scientific meeting this week, researchers report some progress in developing an immunotherapy for ovarian cancer. However, they also outline the considerable challenges that remain before the treatment can be made effective for this and other cancers that have solid tumors.

The researchers - from the Fred Hutchinson Cancer Research Center (Fred Hutch) in Seattle, WA - presented the findings at the annual meeting of the American Association of Cancer Research in Washington, D.C.

Estimates from the American Cancer Society suggest that, in the United States, around 22,440 women will be diagnosed with ovarian cancer and approximately 14,000 will die from the disease during 2017.

The cancer begins in cells of the ovaries - reproductive glands found only in women. Each woman normally has two ovaries, situated on each side of the uterus inside the pelvis. The ovaries produce eggs that travel to the uterus through the fallopian tubes. If an egg is fertilized by male sperm, it develops into a fetus.

Dr. Kristin Anderson, an immunotherapy researcher at Fred Hutch who presented the findings at the meeting, says that while ovarian cancer is not as common in the U.S. as other cancers with solid tumors, it has a low rate of survival and a high rate of relapse. The main reason is that the cancer does not cause obvious symptoms and is often advanced by the time it is diagnosed.

Immunotherapy is a relatively new area of medicine that is showing promising results in the treatment of cancer. The approach uses the patient's own immune system to fight disease.

The new study concerns a method called adoptive T cell transfer. In this approach, immune cells called T cells are taken from the patient's own blood and trained to target and destroy cancer cells. Then, after multiplying in the laboratory, the primed cells are returned to the patient's body. Sometimes donor cells are used instead.

Fast facts about ovarian cancer

Fred Hutch have a number of teams researching immunotherapy cancer treatments. In particular, Dr. Anderson and colleagues have reported success in using adoptive T cell transfer to treat blood cancers.

In her meeting presentation, Dr. Anderson reported progress on applying lessons learned from that work to the treatment of solid tumors.

The researchers found that ovarian cancer cells overproduce two proteins - WT1 and mesothelin - and showed that T cells engineered to target them can kill mouse and human ovarian cancer cells in the laboratory.

They also found that the engineered T cells significantly increased survival in a mouse model of ovarian cancer.

However, Dr. Anderson cautions that there is still some way to go before adoptive T cell transfer is ready for clinical trials in human patients.

The team discovered that, compared with treating blood cancers, it is much harder to apply T cell therapy to solid tumors like breast, ovarian, lung, and pancreatic cancers.

In leukemia and lymphoma, the engineered T cells can be infused directly into the bloodstream to target the blood cancer. However, access to solid tumors that are tucked away inside the body poses some major challenges. Among these are issues concerning the tumor microenvironment - a mixture of noncancerous cells, molecules, and extracellular matrix in and around the tumor.

Dr. Anderson outlines three particular challenges posed by the tumor microenvironment that they are working on. One is the fact that there are cells and proteins in the tumor microenvironment that send signals to the T cells that tell them to shut down or simply ignore the tumor cells.

The team suggests that there are some existing drugs called checkpoint inhibitors that they could explore to tackle this problem. Another approach could be to engineer the T cells to block these particular signals.

The second challenge is that ovarian tumor cells and neighboring blood vessels send self-destruct signals to the T cells, causing them to commit suicide before they can attack cancer cells.

The Fred Hutch team is already working on a solution to this second challenge in the form of a fusion protein that boosts the T cells' anticancer activity when they receive these self-destruct signals.

The third challenge that the researchers have identified in the solid tumor microenvironment is the problem of low sugar. To grow as rapidly as they do, ovarian cancer cells devour sugar, which they get from their environment.

However, the engineered T cells also need this sugar to fuel their journey to, and attack on, the cancer cells. The researchers at Fred Hutch are looking for a way to engineer the T cells so that they use a different source of energy.

Dr. Anderson says that while they are currently focusing on ovarian cancer, they believe that these solutions will also help to make progress on using adoptive T cell transfer with other solid tumors.

"If we can solve some of the issues that really plague us with these hard ones, then we can more readily apply [the solutions] to cancers that have fewer of these hurdles," she explains, as she concludes:

"Tumor microenvironment issues come hand-in-hand with working on solid tumors."

The team hopes to start a human clinical trial of adoptive T cell transfer for ovarian cancer in the next few years.

Man Receives Reprogrammed" Stem Cells From Donor In Medical … – IFLScience

Last week, a patient with blurry vision in his right eye walked into a doctors office and became the first person to receive reprogrammed stem cells from a donor to treat his age-related macular degeneration.

The patient a Japanese man in his 60s is not alone, as four other patients have been approved for the procedure by Japan's health ministry. The first medical case was reported on March 28 by Nature.

In a one-hour operation by surgeon Yasuo Kurimoto, the patient received skin cells from a human donor at Kobe City Medical Center General Hospital. The donors skin cells were reverse engineered into induced pluripotent stem (iPS) cells. These cells are often seen as a game-changer in the world of regenerative medicine as they have the ability to become almost any type of cell in the body.

In this case, the iPS cells were turned into retinal cells, which were then implanted into the retina of the patient, who has age-related macular degeneration. It is hoped the procedure will stop the progression of the disease, which can lead to blindness. The transplantis not being touted as a cure for the condition, merely a prevention methodfrom further damage.

During the procedure, the surgical team injected 50 microliters of liquid containing 250,000 retinal cells into the patients eye, according to the Japan Times. The real test, however, will be the next phase of monitoring.

What sets this transplant apart is also what makes the recovery process precarious. Doctors will need to keep a careful watch on the patient, as iPS cells from a donor are not a genetic match and could cause an immune rejection.

At this point, you might remember a similar case in 2014 with a Japanese woman at the same hospital. She also received retinal cells derived from iPS cells, however hers were taken from her own skin, not a donor's.

"A key challenge in this case is to control rejection," said Riken researcher Masayo Takahashi to the Japan Times. "We need to carefully continue treatment."

In an update, the team said the Japanese woman was doing well and her vision had not declined. They decided to change track and use donor cells for this study because it holds a more viable future for such transplants.

It's hoped, if all goes well here, that researchers can create a bank of donor stem cells. Such a future would cut down on costs and reduce wait times, as cultivating ones own cells can take several months. However, there's stillmuch to be done.

After the procedure, Takahashi told a press conference that the surgery went well. They will continue to monitor the situation and provide further updates in the future.

Bangladeshi patients treated with stem cell therapy in city – Mumbai … – Mumbai Mirror

Bangladeshi activist and city-based medical centres collaborate to provide life-saving treatment for the three patients.

A Navi Mumbai-based treatment centre used stem cell therapy for the first time on three Bangladeshi patients suffering from an incurable muscular dystrophy.

The trio have been suffering from a rare disease called Duchenne Muscular Dystrophy, which causes progressive muscle degeneration, since birth. The disease limits the lifespan of the patient to just 30 years.

The doctors took stem cells from the patients bone marrow in the hip bone, processed it and injected it back into their bodies. The coordinator between the patients and the treating centre, Avantika Patil said, The patients are also undergoing physiotherapy and occupational therapy while we wait for the results of the procedure to show.

The treatment was made possible by the efforts of a Bangladeshi activist, Noor Khan, a Mumbai-based organisation, Meditourz, which worked in collaboration with a brain and spine institute from Navi Mumbai, NeuroGen.

It was NeuroGen which learnt about the three patients from an article in the international media and offered to treat their disease.

Of the three patients, the youngest, Shorab (8) has a mild disorder. This early medical intervention is expected to make his life less painful. However, the other two patients, Abdus (24) and Rahinul (14) are at a progressive stage.

Their father, Tofazzal Hossain, had even sought mercy killing from Bangladesh government for the duo as he could not afford the cost of their treatment. The travel arrangements were made in coordination with the Indian government. Free round-trip tickets were offered to six persons the patients and their caretakers who accompanied them to Mumbai from Kolkata, by Air India.

Durability of CAR T-cell therapy response may depend on … – Medical Xpress

April 4, 2017

Although most patients with relapsed B-cell acute lymphoblastic leukemia (B-ALL) experienced complete response after treatment with a type of CAR T-cell immunotherapy, pretreatment disease burden impacted the durability of the responses and long-term survival, according to data from a clinical trial presented here at the AACR Annual Meeting 2017, April 1-5.

"Adult patients with relapsed or refractory ALL have extremely poor outcomes, with the five-year survival rate being less than 10 percent. Therefore, there is a clear need to develop effective therapy for these patients," said Jae Park, MD, assistant attending physician at Memorial Sloan Kettering Cancer Center (MSKCC) in New York.

"To this end, we and other groups have developed and tested CD19-specific CAR T-cell therapy [19-28z CAR T-cell therapy] and have reported encouraging results, with high initial complete response rates in patients with B-ALL. However, relapses are common, even after achieving seemingly deep remission, and severe toxicities have been observed in some patients," Park noted.

Park and colleagues, therefore, retrospectively analyzed data from a prospective clinical trial that tested 19-28z CAR T-cell therapy to identify patients who benefited the most from this therapy. All of the 51 adult patients in this trial had relapsed or refractory B-ALL after one or more conventional multiagent chemotherapy.

The researchers measured disease burden prior to CAR T-cell infusion in all patients and divided them into two cohorts those who had minimal residual disease (MRD) with less than 5 percent blast cells in bone marrow (20 patients), and those who had morphologic disease, with 5 percent or more blast cells in bone marrow (31 patients).

Complete response rates in the MRD cohort and morphologic disease cohort were 95 percent and 77 percent, respectively, which was not statistically different. After a median of 18 months of follow-up, median event-free survival and overall survival could not be computed for those in the MRD cohort (because most patients were still disease-free and alive), but they were 6.3 months and 17 months, respectively, for those in the morphologic disease cohort.

The study also found that long-term survival did not improve for patients in either cohort by having a hematopoietic stem cell transplant (HSCT) after CAR T-cell therapy.

"While more patients and longer follow-up will be needed to adequately address the significance of HSTC, the result of this analysis raises a question as to whether 19-28z CAR therapy can be considered as a definitive, curative therapy rather than a bridge to stem cell transplant, at least in a subset of patients," Park noted.

"Our data suggest that incorporation of 19-28z CAR T cells at the time of MRD following first-line chemotherapy will maximize the durability of CAR T-cell mediated remissions and survival and can potentially spare these high-risk patients from HSCT, rather than waiting until they relapse morphologically and then trying CAR T-cell therapy when it is less likely to achieve a durable long-term outcome," Park added.

Patients from the MRD cohort fared well in terms of side effects as well, compared with those in the morphologic disease cohort. Two of the major side effects associated with CAR T cells, cytokine release syndrome (CRS) and neurotoxicity, occurred in 42 percent and 58 percent of the patients, respectively, in the morphologic disease cohort, compared with 5 percent and 15 percent, respectively, in those from the MRD cohort. No case of cerebral edema was observed in either cohort of this study, Park noted.

A limitation of the study is that this is a retrospective analysis and the findings will need to be validated prospectively, Park said. Further, the analysis on the impact of post-CAR allogeneic HSCT was limited by a relatively small sample size in each cohort as the study was not designed to specifically answer or address that question.
