Novel stem cell therapy for repair of knee cartilage – Mayo …

Mayo Clinic offers a unique regenerative medicine approach for repairing knee cartilage, which can be completed in a single surgery. The Food and Drug Administration approved the use of this technique, known as recycled cartilage auto/allo implantation (RECLAIM), in a trial utilizing the stem cell bank in the Mayo Clinic Center for Regenerative Medicine.

"Mayo is unique in having an adipose-derived allogeneic stem cell bank. It provides us with donor mesenchymal stem cells, which we mix with recycled autologous cells to quickly obtain enough cells to fill the patient's cartilage defect without operating twice," says Daniel B. Saris, M.D., Ph.D., an orthopedic surgeon at Mayo Clinic in Rochester, Minnesota, who specializes in knee surgery and focuses on regenerative medicine.

RECLAIM mixes chondrons from debrided tissue with donor autologous stem cells to create a biologic filler for the repair of damaged knee cartilage. The procedure can be completed in a single surgery.

Dr. Saris previously performed the RECLAIM cartilage repair technique in Europe. "The results, about four years out, are very good comparable to or better than other cell therapies, except these patients achieve normal function after surgery about six months more quickly," he says.

Planning is underway for a clinical trial at Mayo Clinic. RECLAIM is used to repair symptomatic cartilage defects, usually resulting from trauma or an athletic injury. The procedure might be suitable for nonarthritic patients ages 18 to 50 who have fresh cartilage defects.

Existing cell therapy to repair knee cartilage generally involves surgically debriding the cartilage defect and then taking a biopsy of healthy cartilage from the patient. The biopsy is cultured in an outside laboratory, and the cultured cells are implanted weeks later. "We wanted to improve this technique because during the waiting period, the patient's life is on hold, costs increase and the logistics can be complex," Dr. Saris says.

RECLAIM's innovation starts with saving the patient's debrided tissue. "That tissue is always a bit frilly and is normally discarded," Dr. Saris says. "But we found that the cells in that tissue are still very viable. We recycle them."

The resected tissue is processed and, using a rapid isolation protocol, digested into chondrons. Mixing the chondrons with allogeneic stem cells from the stem cell bank provides sufficient cells to immediately re-inject into the patient.

"This is a highly innovative procedure," Dr. Saris says. "You have to find an intricate balance loading enough cells to grow into healthy tissue but not overloading the space so the cells are squished when the patient starts rehab."

Most patients return home on the day of surgery. They generally need to wait nine to 12 months before a full return to sports; that interval provides time for the cartilage to grow and the patient to regain muscle control. "But apart from sports, patients can go back to normal life within days and physical activities within three to four months of surgery," Dr. Saris says.

Mayo Clinic's multidisciplinary approach provides the range of care needed by patients at all stages of knee cartilage repair. Before surgery, advanced imaging helps pinpoint the cartilage defect. "Our physiotherapists and athletic trainers also determine prior to surgery how we can optimize the patient's musculoskeletal control and function, and then work with the patient on rehab after surgery," Dr. Saris says.

Mayo Clinic also has the breadth of orthopedic expertise to manage problems that patients often experience alongside damaged knee cartilage, such as varus deformity and anterior cruciate ligament or meniscus lesions. "If a cartilage repair procedure fails, it's generally because not enough attention was paid to other factors the meniscus or the knee's alignment or stability," Dr. Saris says. "Our unique multidisciplinary team looks at all aspects of a patient's care. Our chances of success for these complex biological reconstructions is therefore high."

The cartilage repair technique illustrates Mayo Clinic's commitment to applying regenerative medicine to orthopedic surgery. "We are focused on patient-centered progress," Dr. Saris says. "We want to make sure there is a safe and efficacious portfolio of regenerative medicine therapies for musculoskeletal problems."

‘I’m not losing my boy,’ sobs mum after son is diagnosed with cancer for third time – Mirror Online

By adminMarch 15, 2020Stem Cell Treatment

The Peers family were overjoyed when doctors told them Callum had beaten cancer.

Life returned to normal but, tragically, it would not stay that way.

The battling ten-year-old, who has twice successful fought cancer, has the disease once again.

This time the odds are heavily stacked against him. Doctors here give him just a ten per cent chance of living more than five years.

But his parents are determined to fight on and are pinning their hopes on pioneering drug trials.

They are trying to raise 150,000 to get Callum treatment in the US that is not available on the NHS.

Callums mum Nicola, 37, said: Seeing my son fight this disease for seven years has been heartbreaking but he has never given up.

Hes fought it and beaten it twice and I know he can do it again. We must give him that chance. I am not losing my boy.

Callum, of Leigh, Gtr Manchester, was just three when he began getting symptoms. Nicola first took Callum to his GP with stomach pains.

In June 2013, after hed turned four, he was diagnosed with an aggressive stage-4 neuroblastoma.

She said: It was such a shock when they told us, the last thing we expected. It was a body blow.

I was heartbroken but I had to carry on and be strong for Callum.

We told him he had a lump in his tummy and was having medicine for it. He was a little hero and never complained.

Callum had an operation to remove a tumour in his stomach and gruelling chemotherapy, immunotherapy and stem cell treatment.

He lost his hair, endured sickness, lethargy, high temperatures and spent months in hospital.

Then, in December 2014, the family got the news they were hoping for when his scans came back all clear.

Nicola recalled: We were over the moon. Life slowly went back to normal and we started going on family caravan holidays again.

But just over two years later, in January 2017, when Callum was getting ready for school he complained of feeling unwell.

Nicola noticed a lump on his neck. An emergency scan at the hospital confirmed the cancer had returned.

Nicola said: To get that news a second time was devastating. It could easily have broken us, but we had to fight on.

Callum had three types of chemo and after 12 months in and out of hospital he had kicked the cancer again.

But in August last year there was a lump on his neck and Nicola knew what to expect. The cancer had spread to the right side of his stomach. She said: Id thought after his treatment had finished the second time we were going to go back to normal.

Being told again and again your boy has cancer is awful.

Since then a tumour on Callums chest has been surgically removed and, days before his tenth birthday, another growing on his spine, which could have paralysed him, was taken out.

He has been through more chemo and radiotherapy, been rushed into intensive care with complications four times.

He spent his Christmas at Great Ormond Street hospital in London. Nicola said: Callum is the definition of a fighter. I know he can beat this again and beat it for good.

Treatment options in the UK for Callum have run out but Nicola and his dad Alan, 56, brothers Jake, 19, Joshua, 18, and Cameron, nine, and sister Bethany, 17, arent giving up hope.

Helen Devos Childrens Hospital in Michigan is one of the few centres offering a treatment that works by targeting specific cancer stem cell pathways. Nicola spoke to consultants there and said: Children are going over there and are still clear of disease years and years later.

Callum has been through so much. He just carries on and he deserves this chance.

Were all feeling really hopeful. Its been proven to work.

She added: I know Callum can win his fight if we can give him the best possible chance.

CytoDyn’s First mTNBC Patient in Phase 1b/2 is in Remission and Oncologist Ordered Termination of Treatment with Carboplatin (chemotherapy drug) and…

By adminMarch 15, 2020Stem Cell Treatment

VANCOUVER, Washington, March 12, 2020 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTC.QB: CYDY), (CytoDyn or the Company), a late-stage biotechnology company developing leronlimab (PRO 140), a CCR5 antagonist with the potential for multiple therapeutic indications, announced today that the FDA recommended that the Company request a preliminary Breakthrough Therapy designation meeting. Meanwhile, the Company continues reporting very positive data for its mTNBC and MBC patients.

Metastatic triple-negative breast cancer (mTNBC), an aggressive histological subtype, has a poor prognosis. In addition, metastatic breast cancer (MBC) is breast cancer that has spread beyond the breast and lymph nodes to other organs in the body (typically the bones, liver, lungs, or brain). Both types of cancer pose significant challenges for patients due to their aggressiveness and limited treatment options. An integral part of CytoDyns mission and purpose is to provide effective therapeutic solutions to these patients. Clinical results from the first cancer patient in the Companys Phase 1b/2 mTNBC trial are as follows:

Patient #1: Enrolled in mTNBC Phase 1b/2 with first treatment in late September 2019. CTC (circulating tumor cells) dropped to zero after two treatments with leronlimab and carboplatin. Total CTC and EMT (Epithelial Mesenchymal Transition in Tumor Metastasis) dropped to zero after about one month of treatment with leronlimab (once-a-week 350 mg dose). Results from the patients earlier CT scan indicated a more than 25% tumor shrinkage within the first few weeks of treatment with leronlimab and carboplatin. After approximately five months of treatment with leronlimab and carboplatin, the patient not only has zero CTC and zero EMT, but also zero detectible CAML (cancer-associated microphages like cells). The patients oncologist has now ordered this patients treatment to consist only of leronlimab and has discontinued treatment with carboplatin (a chemotherapy drug). Testimony provided to the Company from the patient stated: So far my experience with leronlimab has been very positive. I didnt expect it to be so easy and tolerable with virtually ZERO side effects. The results so far have been super impressive. Im very grateful to be part of this clinical trial study and it really makes me feel hopeful that this otherwise fatal disease can be turned into a manageable disease in the near future.

Bruce Patterson, M.D., chief executive officer and founder of IncellDx, a diagnostic partner and advisor to CytoDyn, commented, The FDA recommendation for a meeting on CytoDyns BTD application is a tremendous opportunity to further discuss the mechanism of action and to summarize the promising results from patients enrolled following the submission of the application. Included in this discussion will be the recent decision by the oncologist of Patient #1 to, based on continued unremarkable changes to her condition, remove carboplatin from the patients regimen with continued therapy with leronlimab. Nader Pourhassan, Ph.D., president and chief executive officer of CytoDyn, added: Our first patient in the Phase 1b/2 trial has shown remission of the tumor and her oncologist has attributed this primarily to leronlimab and discontinued the carboplatin (a form of chemotherapy). This patients latest results of zero CTC, EMT, and CAML is unique and we now have another patient with three zeros identical to the first patient. We are very excited to continue enrolling patients and hopeful to have our first patient treated in our basket trial for 22 solid tumor cancers very soon. We are also very hopeful to have several more patients in our Phase 1b/2 mTNBC trial before our preliminary meeting with the FDA for Breakthrough Therapy designation.

About Triple-Negative Breast CancerTriple-negative breast cancer (TNBC) is a type of breast cancer characterized by the absence of the three most common types of receptors in the cancer tumor known to fuel most breast cancer growthestrogen receptors (ER), progesterone receptors (PR) and the hormone epidermal growth factor receptor 2 (HER-2) gene. TNBC cancer occurs in about 10 to 20 percent of diagnosed breast cancers and can be more aggressive and more likely to spread and recur. Since the triple-negative tumor cells lack these receptors, common treatments for breast cancer such as hormone therapy and drugs that target estrogen, progesterone, and HER-2 are ineffective.

About Leronlimab (PRO 140) The U.S. Food and Drug Administration (FDA) have granted a Fast Track designation to CytoDyn for two potential indications of leronlimab for deadly diseases. The first as a combination therapy with HAART for HIV-infected patients and the second is for metastatic triple-negative breast cancer. Leronlimab is an investigational humanized IgG4 mAb that blocks CCR5, a cellular receptor that is important in HIV infection, tumor metastases, and other diseases including NASH. Leronlimab has successfully completed nine clinical trials in over 800 people, including meeting its primary endpoints in a pivotal Phase 3 trial (leronlimab in combination with standard antiretroviral therapies in HIV-infected treatment-experienced patients).

In the setting of HIV/AIDS, leronlimab is a viral-entry inhibitor; it masks CCR5, thus protecting healthy T cells from viral infection by blocking the predominant HIV (R5) subtype from entering those cells. Leronlimab has been the subject of nine clinical trials, each of which demonstrated that leronlimab can significantly reduce or control HIV viral load in humans. The leronlimab antibody appears to be a powerful antiviral agent leading to potentially fewer side effects and less frequent dosing requirements compared with daily drug therapies currently in use.

In the setting of cancer, research has shown that CCR5 plays an important role in tumor invasion and metastasis. Increased CCR5 expression is an indicator of disease status in several cancers. Published studies have shown that blocking CCR5 can reduce tumor metastases in laboratory and animal models of aggressive breast and prostate cancer. Leronlimab reduced human breast cancer metastasis by more than 98% in a murine xenograft model. CytoDyn is therefore conducting a Phase 1b/2 human clinical trial in metastatic triple-negative breast cancer and was granted Fast Track designation in May 2019. Additional research is being conducted with leronlimab in the setting of cancer and NASH with plans to conduct additional clinical studies when appropriate.

The CCR5 receptor appears to play a central role in modulating immune cell trafficking to sites of inflammation and may be important in the development of acute graft-versus-host disease (GvHD) and other inflammatory conditions. Clinical studies by others further support the concept that blocking CCR5 using a chemical inhibitor can reduce the clinical impact of acute GvHD without significantly affecting the engraftment of transplanted bone marrow stem cells. CytoDyn is currently conducting a Phase 2 clinical study with leronlimab to further support the concept that the CCR5 receptor on engrafted cells is critical for the development of acute GvHD and that blocking this receptor from recognizing certain immune signaling molecules is a viable approach to mitigating acute GvHD. The FDA has granted orphan drug designation to leronlimab for the prevention of GvHD.

About CytoDyn CytoDyn is a biotechnology company developing innovative treatments for multiple therapeutic indications based on leronlimab, a novel humanized monoclonal antibody targeting the CCR5 receptor. CCR5 appears to play a key role in the ability of HIV to enter and infect healthy T-cells. The CCR5 receptor also appears to be implicated in tumor metastasis and in immune-mediated illnesses, such as GvHD and NASH. CytoDyn has successfully completed a Phase 3 pivotal trial with leronlimab in combination with standard anti-retroviral therapies in HIV-infected treatment-experienced patients. CytoDyn plans to seek FDA approval for leronlimab in combination therapy and plans to complete the filing of a Biologics License Application (BLA) in the first quarter of 2020 for that indication. CytoDyn is also conducting a Phase 3 investigative trial with leronlimab as a once-weekly monotherapy for HIV-infected patients and plans to initiate a registration-directed study of leronlimab monotherapy indication, which if successful, could support a label extension. Clinical results to date from multiple trials have shown that leronlimab can significantly reduce viral burden in people infected with HIV with no reported drug-related serious adverse events (SAEs). Moreover, results from a Phase 2b clinical trial demonstrated that leronlimab monotherapy can prevent viral escape in HIV-infected patients, with some patients on leronlimab monotherapy remaining virally suppressed for more than five years. CytoDyn is also conducting a Phase 2 trial to evaluate leronlimab for the prevention of GvHD and a Phase 1b/2 clinical trial with leronlimab in metastatic triple-negative breast cancer.

A new therapeutic approach against COVID-19 Pneumonia – Institute for Ethics and Emerging Technologies

By adminMarch 15, 2020Stem Cell Medical Center

The novel coronavirus disease 2019 (COVID-19) has grown to become a global public health emergency. Currently, no specific drugs or vaccines are available to cure the patients with COVID-19 infection. Hence, there is a large unmet need for a safe and effective treatment for COVID-19 infected patients, especially the severe cases. A new study offers a promising pathway for developing such a treatment.

The new approach involves intravenous transplantation of mesenchymal stem cells (MSCs) into the patients. It was successfully tested in 7 COVID-19 patients, in Beijing YouAn Hospital, Capital Medical University, China. The results are published in the scientific journal Aging and Disease, entitled "Transplantation of ACE2- Mesenchymal Stem Cells Improves the Outcome of Patients with COVID-19 Pneumonia".

http://www.aginganddisease.org/article/0000/2152-5250/ad-0-0-216.shtml

The study was conducted by a team led by Dr. Robert Chunhua Zhao, with Shanghai University and Chinese Academy of Medical Sciences & Peking Union Medical College, China.

Moreover the study was reviewed by a scientific committee of the International Society on Aging and Disease (ISOAD) and the recently established UNESCO-affiliated committee on Anti-Aging and Disease Prevention http://www.aginganddisease.org/article/2020/2152-5250/ad-11-1-212.shtml

Based on the 14 days observation, MSCs could cure or significantly improve the functional outcomes of all the seven tested patients without observed adverse effects, contrary to 3 controls. The pulmonary function and symptoms of these seven patients were significantly improved after MSC transplantation. Among them, one severe and two common patients recovered and were discharged in 10 days after the treatment. The improvement was particularly dramatic for an elderly (65 y.o.) male patient in severe critical condition. All of his primary and secondary outcomes improved: the inflammation status, the oxygen saturation, and the functional biochemical indicators returned to normal reference values in 2~4 days after the treatment.

The presented evidence suggests that the therapeutic effects are based on the immunomodulatory capacity of mesenchymal stem cells (restoring the balance of the immune system). The coronavirus infection can stimulate a terrible cytokine storm in the lung, disrupting the balance of cytokines (signaling molecules of the immune system) such as IL-2, IL-6, IL-7, GSCF, IP10, MCP1, MIP1A and TNF cytokines, followed by the edema, dysfunction of the air exchange, acute respiratory distress syndrome, acute cardiac injury and the secondary infection, which may lead to death. The bone-marrow derived MSCs could inhibit the over-activation of the immune system and promote endogenous repair by improving the microenvironment, thus they could represent a safe and effective treatment for patients with COVID-19 pneumonia, especially for the patients in critically severe conditions. A larger validation study is required and is already underway, yet the initial results are encouraging.

Notably, the coronavirus-infected pneumonia is more likely to affect older individuals, especially older males, with comorbidities, resulting in their severe and even fatal respiratory diseases such as acute respiratory distress syndrome. In other words, aging appears to be the main risk factor for bad outcomes. However, the cure essentially depends on the patient's own immune system. When the overactivated immune system kills the virus, it produces a large number of inflammatory factors, leading to the severe cytokine storms. This suggests that the main reason for the organs damage may be the virus-induced cytokine storm. Older subjects may be much easier to be affected due to immunosenescence. The study showed remarkable recovery of the elderly patients thanks to restoring their immune function.

Thus, the study may have a broader significance, even beyond the treatment of the severe coronavirus disease. This study exemplifies that the general therapeutic improvement of the immune system in the elderly can improve outcome and survival, which may have more general relevance for other aging-related communicable diseases. Thus, this study may inspire and pave the way for further promising directions to investigate the connection between aging and disease, and to treat both communicable and non-communicable aging-related diseases.

The Romanian journalist Laura tefnu spoke with Dr. Ilia Stambler about the broader implications of this research. Ilia Stambler is a co-author in this study who was involved in the study review, interpretation and discussion. He serves as the Outreach Coordinator of the International Society on Aging and Disease (ISOAD) and Director of Research and Development at Shmuel Harofe Geriatric Medical Center in Israel.

Q: How does it feel to be part of the team which discovered a groundbreaking treatment for what is currently considered one of the biggest global challenges?

A: I feel very honored to be included in this extended international team. I hope this team continues its work that will also involve additional collaborations.

Q: As a researcher, what did you find most interesting about this novel coronavirus? What seems most threatening about this new virus?

A: The spreading ability of this virus is relatively high and it has the capacity to affect the entire global population. This is what makes this virus a particularly strong concern for global public health. The social effects of this epidemic are also of great importance. In a sense, this virus is testing the strength of our public health systems. Will the immunity of our public healthcare be strong enough to contain it? I hope it is.

Q: Did the discovery of this groundbreaking new therapeutic approach make you more optimistic (when it comes to containing and limiting the damage of Covid-19)? In which sense (where was your optimism before the discovery)?

A: I was optimistic before, as I believe that, same as for many infectious diseases in the past, also for this disease, effective therapeutic and preventive measures will be found and used. This work further increased my optimism. Of course, this is an initial study, and this is only one of the potential means in the therapeutic, preventive and hygienic arsenal. More research and confirmation will be needed. Yet, even at this stage, the clear positive result of this study shows that it is indeed possible to improve the outcomes for COVID-19 patients even in severe conditions. Moreover, it gives more hope that effective treatments can be sought and found also for other aging-related infectious diseases and conditions.

Q: Is there an explanation regarding the reasons why Covid-19 seems to pardon children and affects the most elder individuals, especially men?

A: There is yet no clear or fully agreed explanation. But a plausible cause may be due to the so called immuno-senescence phenomenon, or the inability of the aging immune system to cope with new threats and restore the immune balance following the infection. In men the immuno-senescence effects are often more strongly present than in women. Thus, aging appears to be the main risk factor for this disease and if we really wish to defeat this epidemic, we need to address this main risk factor, in other words, we need to therapeutically intervene and ameliorate the degenerative aging process. The proposed mesenchymal stem cell therapy shows the so-called immuno-modulation effects or the ability to generally improve the immune system, help restore the immune balance after disturbances, especially for the elderly. And this can be the more general explanation for its effects against the aging-related COVID-19 pneumonia, as well as potentially other aging-related diseases.

Q: How did you manage to find so fast a treatment that is responding so well?

A: The mesenchymal stem cell treatment has been researched and developed by Dr. Zhao and his team for many years, and indicated positive effects for multiple health conditions. It is exactly because of the common and critical role of the immune system impairment in all these conditions, that the treatment developed by Dr. Zhaos team was already in place and could be immediately used also for this condition dependent on the immune function. Moreover, the success of this therapy against COVID-19 can further boost the research and therapy of other immunity-dependent health conditions and diseases, especially aging-related diseases, due to the common mechanisms of action.

Q: How may this discovery change the game?

A: Unlike other public health measures, like quarantine and hygiene, that can be very quickly applied, the research, development, regulatory approval and application of new therapies is a much slower process. So we should first of all apply the public health measures to contain the epidemic. But the hope is that this therapy will undergo further research and validation as soon as possible, and in case of validated efficacy and safety, will be used in as many patients who need it as possible, as soon as possible. That is exactly why we need to accelerate the research, development and application of promising new therapies. When the new therapy enters wide clinical practice, there are grounds to believe it can improve the health and even save the lives of many patients, not only suffering from COVID-19, but also other conditions.

Q: Which was the response/reaction of authorities after you published the results of your research?

A: The outreach to the authorities in several countries has only started. Moreover, the study is only initial and it is too early to make policy recommendations. A larger validation study is required. Yet, if there is even a slight possibility this could become a life-saving therapy for COVID-19 patients and others, this opportunity should not be missed by the decision makers.

Q: Some treatments are more expensive than others. Will the treatment you discovered be accessible to people, or the cost for producing it will limit its accessibility?

A: The cells for this treatment can be mass produced and can be rather affordable. Of course, the actual price will depend both on the scale of production and pricing policies. And this is already a question that goes beyond pure technology, but becomes a question about the social means to make new therapies available to all. This should also be a crucial part of the public discussion about the social need to promote the rapid research and development as well as broad application of new therapies that are proven to be safe and effective.

Q: Which are the best measures a country can take to limit the spread and the consequences of the novel coronavirus?

The usual quarantine and public hygiene measures are the most feasible and effective: minimization of large gatherings, minimization of travel, cleanliness. We should hope and work for new effective therapies to arrive as soon as possible. But so far public health measures are the most effective and feasible.

Woman meets stranger who saved her life and allowed her to become a mum – Mirror Online

By adminMarch 15, 2020Stem Cell Clinic

As Jo Kelly met her hero for the first time, she struggled to find the words to thank him for the two most precious of gifts.

Stem cell donor Stefan Berens did not just save Jo after she was given only months to live. He also gave her the opportunity to become a mum to baby Phoebe.

So Jo showed her gratitude the only way she could. She embraced Stefan then introduced him to her beautiful daughter.

Jo, 34, said: Meeting Stefan was one of the best experiences of my life. It felt like meeting long-lost family. He called me his blood sister, so I knew he felt the same way.

Introducing him to Phoebe was like showing him the ultimate symbol of my recovery. If it wasnt for him, she wouldnt be here. I can feel myself getting tearful when I say that.

Stefan, 32, an economist from Germany, said: I was very nervous about meeting Jo, but it felt so natural. There was a unique bond between us. Meeting Phoebe was the cherry on top, realising she wouldnt exist without me. I am so happy for them.

Jo was just 22 when she was diagnosed with blood cancer Hodgkin Lymphoma in 2007. Despite intensive radiotherapy and chemotherapy, the cancer spread to her lungs and bones.

Three years later, doctors told her the cancer was terminal and she would not live to see Christmas.

Jo had been dating Pete Ames, himself a testicular cancer survivor, for just six months. She said: A few weeks later, we were painting my room and Pete burst into tears. He said he didnt want me to leave this world not being his wife.

Business analyst Pete, now 35, decorated his house with fairy lights and wrote, I love you on the walls in 25 different languages to pop the question. The couple then planned their wedding in just eight weeks.

Jo said: I had an IV drip taped to the underside of my arm, but it was an incredible day.

Days before the wedding, Jo was given a new drug which stopped the cancer progressing, before another drug sent it into remission. For the first time, Jo was stable enough for a stem-cell transplant.

But blood disease charity Anthony Nolan only found one potential lifesaver with a matching tissue type on the worldwide register. That person was Stefan, who joined the register in his home town of Bielefeld, North West Germany.

Jo said: We were terrified he might not want to go through with it, but everything fell into place.

Stefan said: My question was never, Should I do this?. It was, How do I help?.

Stefan made the 360-mile round trip from Hamburg, where he was an intern, to a clinic in Berlin to donate. Jo had her transplant in 2012, but the chemo she needed to kill off her immune system before she received Stefans cells left her so weak she nearly died.

She said: There was one night where I hit rock bottom. I knew if I chose, I could pass away quietly. But I had to keep trying for Pete and my parents.

Jo slowly recovered and wrote a thank you letter to Stefan shortly after the life-saving transplant.

She never received Stefans reply and believes it was delivered to an old address.

Their incredible story might have ended there. But nearly two years ago Jo, who was left infertile by the chemotherapy before her transplant, tried for a baby with husband Pete via IVF.

An embryo made using Petes sperm and a donor egg was implanted in Jos womb. Phoebe was born in March last year and celebrated her first birthday last Thursday.

Jo, a data engineer from Lichfield, Staffs, said: I still marvel at the fact this little soul wasnt really meant to exist, yet she is so special.

Having Phoebe felt like such a big moment, I had to try to tell my donor. Im so glad I did.

Stefan agreed. It was a little bit heartbreaking to find out that Jo didnt receive my first letter. Im so pleased she wrote again. Jo also developed a new passion for running, which she shares with Stefan. She completed the London Marathon on her 33rd birthday in 2018.

When Jo met Stefan in Manchester, she presented him with her marathon medal to thank him for everything. Jo said: It belongs to Stefan as much as me, I wouldnt have it without him.

We joked that he gave me his love of running along with his stem cells.

And she added: Meeting Stefan feels like a fitting conclusion to a huge chapter of my life. I dont know what the future holds, but I hope I can keep in touch with my blood brother.

Rethinking the Definition of Cure as Patients With HIV Wait – Medscape

By adminMarch 14, 2020Stem Cell Medicine

BOSTON A year ago, a man living with HIV walked into the exam room of Maile Young Karris, MD, from the UC San Diego Medical Center. He had seen on the news that there was a cure for HIV, and asked Karris: "How can I get it?"

Karris, who specializes in HIV primary care, explained that although one man then known as the London patient had been off medication for 18 months and remained in remission, that cure, if it were really a cure, was not available to him or, really, to any other patient with HIV.

"I'm often very hopeful. I believe we will get there," she told Medscape Medical News. "We're sort of just one scientific advance away."

But back then, she had to explain that the London patient, like the Berlin patient before him, had to get to the point of almost dying from cancer before the stem cell transplant that changed his immune system was even a possibility, and that both men had undergone a painful and invasive immunologic makeover.

So when it was reported at the virtual Conference on Retroviruses and Opportunistic Infections (CROI) 2020 that the London patient, now identified as Adam Castillejo, is still in remission a year later, even the researcher who performed the transplant was willing to say it's probably a cure.

But that likely won't change the way Karris or other HIV providers care for patients.

When Ravindra Gupta, MD, from University College London, presented the case of the London patient at CROI 2019, he was very careful to say "remission", not "cure".

But when he presented the case at CROI this year, he called it a cure, and he and his colleagues, in their report of the evidence published in the LancetHIV, state that "these findings probably represent the second recorded HIV-1 cure."

In May 2016, Castillejo received a stem cell transplant to treat stage4 Hodgkin's lymphoma, a non-AIDS-defining cancer. That transplant, like the one that Timothy Ray Brown, the so-called Berlin patient, received contained stem cells with two genetic mutations that remove the CCR5 receptor from the surface of the T-cell. Without that receptor, most HIV strains can't invade cells and, therefore, can't proliferate.

When Gupta presented preliminary findings last year, Castillejo had only been off HIV treatment for 18 months and was nearly 2 years out from his transplant. Back then, the team only took blood samples, but they showed that HIV wasn't present.

Then, just last month, samples from Castillejo including blood, plasma, semen, and tissue from his rectum, cecum, sigmoid colon and terminal ileum, and auxiliary lymph nodes were subjected to DNA, RNA, and other testing to see if the virus really was gone.

Although Castillejo's T-cell count is starting to approach where it had been before the transplant, there is no evidence that HIV is replicating in the blood, semen, or tissue samples tested, Gupta reported.

There were remnants of HIV genetic sequences in T-cells and in lymph node samples, though.

"Those can be regarded as so-called fossils," artifacts of past infection, not proof that HIV was still alive in his system, the researchers explain in the published report.

The findings are exciting, said Sharon Lewin, MBBS, PhD, from the Peter Doherty Institute for Infection and Immunity at the University of Melbourne in Australia, who was not involved in the study.

"It makes me think about a new definition of cure," she told Medscape Medical News. It's "the idea that clearing intact virus is what we're doing. And people may well have defective remnants of the virus, but that defective remnant can't replicate."

Of course, this is all still conjecture, she acknowledged. No one knows how long someone has to follow a person like Brown or Castillejo to know for sure that it will never come back. But she seems reassured that Castillejo had made it past the 27-month mark, which is when the viral load of the Mississippi baby rebounded.

When Gupta presented data on the London patient last year, "it was electric," said Rajesh Gandhi, MD, from Massachusetts General Hospital in Boston. "I think most of us remember where we were."

So it's probably not a surprise that people living with HIV were also electrified. It was a topic that popped up in many exam rooms, which some clinicians blamed on newspapers headlines such as "HIV Is Reported Cured in a Second Patient."

And even for patients who weren't asking directly for a stem cell transplant, the question of cure was urgent for many of them.

"I think most of my patients weren't thinking that it is so easy that they want to go through the rigors of chemotherapy," Gandhi told Medscape Medical News. But "people have definitely come in to my clinic asking: 'What type of cure research are you doing?'"

Gandhi said he directs patients back to what does work: a single pill a day to control HIV.

Right now, Gandhi has a patient who has had both cancer and HIV. The cancer is now gone, but the HIV remains. The patient shared his cancer diagnosis with family but still hasn't disclosed his HIV status.

"He could get all the support from his family around cancer, but he never could share his HIV diagnosis," Gandhi said. "I think this is what motivates people to ask about the London patient and the Berlin patient."

People are still afraid of HIV.

Karris has noticed the same thing. Not long ago, a woman came to the clinic and reported that her partner had pulled a knife on her.

"He'd found her HIV meds in her purse and looked it up," Karris explained. "He took a knife to her because she didn't disclose. He said he was going to cut off her fingertips."

The woman has a suppressed viral load, meaning she can't transmit the virus to her partner. California changed its criminal code in 2017 to make HIV nondisclosure a misdemeanor instead of a felony.

"People are still afraid of HIV," Karris said. "Some people hate the idea that they have HIV. This is one reason people stop taking medicine. They tell me: 'I hate coming here. I don't feel sick. And when I come to the clinic, I'm reminded I'm sick. When I take my meds, I'm reminded I'm sick'."

For patients who feel that way, she has three things to offer. One is the concept of undetectable equals untransmittable, meaning that they aren't putting the people they care about in the position to acquire HIV. That's been transformational for many patients, she said.

The second is that new HIV medications are coming soon that will be taken every month or every other month. "That seems helpful for them," she said. "They like the idea of coming in once a month. Then they don't have to think about it every day."

And finally, she said, she's excited to share a new tidbit, also presented at this year's CROI, that people who have CD4 a T-cell count of at least 500cells/mm3 when they start taking medication now have an average lifespan just 3 years less than those in the general public.

"The gap is closing between people living with HIV and those without," she said. "I try to communicate that. It can be mind-blowing for them, to see that they could live as long as anyone else."

Cancer and COVID-19: What you should know – Newswise

By adminMarch 14, 2020Stem Cell Medicine

Newswise The number of COVID-19 cases are expected to continue to grow across the globe in the upcoming months and that means more people will have to take extra measures to help protect themselves and reduce the transmission of the disease. This is particularly important for people with cancer, whose immune systems have often been weakened by their cancer treatments.

But does that mean people with cancer should stockpile hand sanitizer and face masks?

Oncologists Gary Schiller, MD, and Joshua Sasine, MD, PhD, help explain what cancer patients need to know about COVID-19.

Dr. Schiller is a professor of hematology/oncology at the David Geffen School of Medicine at UCLA and director of the hematological malignancies/stem cell transplantation unit, and Dr. Sasine is an assistant professor of medicine and director of the CAR T cell program at the UCLA Jonsson Comprehensive Cancer Center.

Which cancer patients should be concerned about coronavirus?

Sasine: The patients most at risk are those with bone marrow cancers or who have had a bone marrow transplant within the last 12 months. If patients have cancer and are on active chemotherapy, they are also at a higher risk than the general population. This is especially true if they are over the age of 60.

Schiller: Bone marrow transplant recipients who received bone marrow from other people are the most immunocompromised patients we take care of and the group at greatest risk for sustaining a life-threatening complication from an infection.

What does it mean to have a compromised immune system?

Sasine: The body's white blood cells normally clear out infections, like bacteria, viruses, and fungi. When the cells have either decreased in number, function, or both, the immune system is compromised. This can be due to having cancer, HIV, getting chemotherapy, and many other situations. This means that a person is more likely than others to contract an infection and the infection is likely to do more harm than average. It might also last longer.

Are there precautions cancer patients should be taking?

Schiller: Patients who are immunocompromised need to be wary of going into crowds, should maintain good hand washing techniques and should stay away from individuals who have a cough.

Sasine: For most events, canceling plans is ideal. However, sometimes one must weigh the risks and benefits. If there is a very important event (son or daughter is getting married, etc.) this might be a risk worth taking.

Should cancer patients delay travel plans?

Schiller: For patients with malignancies of the blood and bone marrow, and patients who had bone marrow transplants, I absolutely tell them to delay travel. Dont travel right now.

Is it safe for patients to come to the hospital and clinics for treatment?

Schiller: Yes. Weve been working to develop better isolation procedures and policies to isolate the potentially sick patients from our immunocompromised patients. For example, bringing the potentially sick patients in through a different entrance to isolate them in the waiting room and put them in an isolation room for evaluation.

Should patients be wearing a mask or stockpile hand sanitizer?

Schiller: A mask is not sufficient protection and were concerned that if you wear a mask, especially one that is insufficiently protective, then you have a false sense of security and you may put yourself in a position that might compromise your safety. In regards to hand sanitizer, I would like my patients to stockpile on soap and water. That would be more effective than using hand sanitizer repeatedly.
