Perseverance: from theory to therapy. Our story over the last year – and a half

Some of the stars of our Annual Report

It’s been a long time coming. Eighteen months to be precise. Which is a peculiarly long time for an Annual Report. The world is certainly a very different place today than when we started, and yet our core mission hasn’t changed at all, except to spring into action to make our own contribution to fighting the coronavirus.

This latest CIRM Annual Reportcovers 2019 through June 30, 2020. Why? Well, as you probably know we are running out of money and could be funding our last new awards by the end of this year. So, we wanted to produce as complete a picture of our achievements as we could – keeping in mind that we might not be around to produce a report next year.

Dr. Catriona Jamieson, UC San Diego physician and researcher

It’s a pretty jam-packed report. It covers everything from the 14 new clinical trials we have funded this year, including three specifically focused on COVID-19. It looks at the extraordinary researchers that we fund and the progress they have made, and the billions of additional dollars our funding has helped leverage for California. But at the heart of it, and at the heart of everything we do, are the patients. They’re the reason we are here. They are the reason we do what we do.

Byron Jenkins, former Naval fighter pilot who battled back from his own fight with multiple myeloma

There are stories of people like Byron Jenkins who almost died from multiple myeloma but is now back leading a full, active life with his family thanks to a CIRM-funded therapy with Poseida. There is Jordan Janz, a young man who once depended on taking 56 pills a day to keep his rare disease, cystinosis, under control but is now hoping a stem cell therapy developed by Dr. Stephanie Cherqui and her team at UC San Diego will make that something of the past.

Jordan Janz and Dr. Stephanie Cherqui

These individuals are remarkable on so many levels, not the least because they were willing to be among the first people ever to try these therapies. They are pioneers in every sense of the word.

Sneha Santosh, former CIRM Bridges student and now a researcher with Novo Nordisk

There is a lot of information in the report, charting the work we have done over the last 18 months. But it’s also a celebration of everyone who made it possible, and our way of saying thank you to the people of California who gave us this incredible honor and opportunity to do this work.

We hope you enjoy it.

Huge honor, hugely deserved for CIRM-funded stem cell researcher

Dr. Andy McMahon: Photo courtesy USC

Andy McMahon is one of the most understated, humble and low-key people you are ever likely to meet. He’s also one of the smartest. And he has a collection of titles to prove it. He is the W.M. Keck Provost and University Professor in USC’s departments of Stem Cell Biology and Regenerative Medicine at the Keck School of Medicine, and Biological Sciences at the Dornsife College of Letters, Arts and Sciences, a fellow of the American Association for the Advancement of Science, the American Academy of Arts and Sciences, the European Molecular Biology Organization, and the Royal Society.

Now you can add to that list that Andy is a member of the National Academy of Sciences (NAS). Election to the NAS is no ordinary honor. It’s one of the highest in the scientific world.

In a USC news release Dean Laura Mosqueda from the Keck School praised Andy saying: “We’re delighted that Dr. McMahon is being recognized as a newly elected member of the National Academy of Sciences. Because new members are elected by current members, this represents recognition of Dr. McMahon’s achievements by his most esteemed peers in all scientific fields.”

Not surprisingly CIRM has funded some of Andy’s work – well, we do pride ourselves on working with the best and brightest scientists – and that research is taking on added importance with the spread of COVID-19. Andy’s area of specialty is kidneys, trying to develop new ways to repair damaged or injured kidneys. Recent studies show that between 3 and 9 percent of patients with COVID-19 develop an acute kidney injury; in effect their kidneys suddenly stop working and many of these patients have to undergo dialysis to stay alive.

Even those who recover are at increased risk for developing more chronic, even end-stage kidney disease. That’s where Andy’s work could prove most useful. His team are using human stem cells to create mini artificial kidneys that have many of the same properties as the real thing. These so-called “organoids” enable us to study chronic kidney disease, come up with ideas to repair damage or slow down the progression of the disease, even help improve the chances of a successful transplant if that becomes necessary.

You can hear Andy talk about his work here:

CIRM is now funding a number of projects targeting COVID-19, including a clinical trial using convalescent plasma gel, and intends investing in more in the coming weeks and months. You can read about that here.

We are also funding several clinical trials targeting kidney failure. You can read about those on our Clinical Trials Dashboard page – diseases are listed alphabetically.

CIRM Board Meeting Highlights Important Updates to Clinical Trials

Dr. Maria T. Millan, President and CEO of CIRM, presenting the President’s Report

This past Thursday the governing Board of the California Institute for Regenerative Medicine (CIRM) were presented with an update on CIRM’s clinical portfolio, which to date includes 60 clinical trials in various areas including kidney failure, cancer, and other rare diseases.  The full President’s Report gives an update on 15 of these trials, in addition to our landmark Cure Sickle Cell Initiative with the NIH and our various educational programs.

Although we won’t be diving into extensive detail for all of these trials, we wanted to highlight several key updates made in this presentation to demonstrate how our clinical portfolio is maturing, with many of these trials moving towards registration. Classically, registration trials are large Phase 3 trials. Notably, some of the highlighted CIRM trials are small Phase 2 or earlier trials that seek to gain enough safety and efficacy data to support final FDA marketing approval. This is a trend with regenerative medicine programs where trial sizes are often small due to the fact that the affected populations are so small with some of these rare diseases. Despite this, the approaches could allow a so called “large effect size,” meaning the signal of clinical benefit per patient is strong enough to give a read of whether the therapy is working or not. CIRM programs often address rare unmet needs and utilize this approach.

For example, Orchard Therapeutics, which is conducting a phase 2 clinical trial for ADA Severe Combined Immunodeficiency (ADA-SCID), a rare immune disorder caused by a genetic mutation, has shown a long-term recovery of the immune system in 20 patients two years post treatment.  Orchard plans to submit a Biologics License Application (BLA) sometime in 2020, which is the key step necessary to obtain final approval from the Food and Drug Administration (FDA) for a therapy.

“We are thrilled to see encouraging results for this genetically modified cell therapy approach and a path forward for FDA approval,” says Maria T. Millan, MD, President and CEO of CIRM. “CIRM is proud of the role it has played in this program.  We funded the program while it was at UCLA and it is now in partnership with Orchard Therapeutics as it takes the program through this final phase toward FDA marketing approval.  Success in this program is a game changer for patients with ADA-SCID who had no other options and who had no bone marrow transplant donors. It also opens up possibilities for future approaches for this dieaseas as well as the other 6,000 genetic diseases that currently have no treatment.”    

The trial uses a gene therapy approach that takes the patient’s own blood stem cells, introduces a functional version of the ADA gene, and reintroduces these corrected blood stem cells back into the patient. From blood tests, one can readily detect whether the approach is successful from the presence of ADA and from the presence of immune cells that were not previously present. To date, it has been awarded approximately $19 million in CIRM funding.  Additionally, it has received FDA Breakthrough Therapy as well as Orphan Drug Designations, both of which are designed to accelerate  the development of the treatment.

Another trial that was highlighted is Rocket Pharmaceutical’s clinical trial for Leukocyte Adhesion Deficiency-1 (LAD-1), a rare and fatal pediatric disease that affects the body’s ability to combat infections. They have just released initial results from their first patient. This is also a gene therapy approach using the patient’s own blood stem cells. The notable aspect of this trial is that the investigators designed this small phase 1 trial of nine patients to be “registration enabling.”  This means that, if they find compelling data, they intend to bring the experience and data from this trial to the FDA to seek agreement on what would be required to get final marketing approval in order to get this treatment to patients with severe unmet medical needs in the most timely way possible.     

Preliminary results demonstrate early evidence of safety and potential efficacy.  There were visible improvements in multiple disease-related skin lesions after receiving the therapy. They are collecting more data on more patients.  To date, it has received $6.6 million in CIRM funding.

As a unique immuno-oncology approach (using the body’s immune system to battle cancer), CIRM is funding Forty Seven Inc. to conduct a clinical trial for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), both of which are forms of cancer.  They have received Fast Track and Orphan Drug designation from the FDA.

The trial is using an antibody blocking CD47, a “don’t eat me” signal, which allows the body’s own immune cells to seek and destroy cancerous stem cells.  This is combined with chemotherapy to render the cancer stem cells more susceptible to immune destruction.  This trial has received $5 million in CIRM funding thus far.

Other registration phase trials in the CIRM portfolio include the following Phase 3 trials:

Brainstorm Cell Therapeutics, for a fatal debilitating neurodegenerative disease, Amyotrophic Lateral Sclerosis (Lou Gehrig’s disease).  That company has completed enrollment and expects top line results in the final quarter of 2020.

Humacyte, which is testing bioengineered de-cellularized vessels that are implanted to create vascular access that is repopulated by the patients own stem cells to make it more like native vessel.  The company is conducting two Phase 3 trials to compare this bioengineered vessel to synthetic grafts and to the patients’ own vessels for use in hemodialysis, a “life line” for patients with end stage renal disease. Humacyte was the first US FDA Cell Therapy program to receive the Regenerative Medicine Advanced Technologies (RMAT) in March 2017. To date, these trials have been awarded $24 million in CIRM funding.

Medeor Therapeutics has received $11.2M in CIRM funding to conduct a Phase 3 trial in combined blood stem cell and kidney transplantation to induce immunologic tolerance so that the blood stem cells teach the patient’s immune system to recognize the transplanted kidney as its own.  The goal is to remove the need for chronic immunosuppressive medications, that have its own complications. If successful, transplant recipients would not need to “trade one chronic condition for another.”

Donor blood stem cells and T cells could help patients wean off immunosuppressive drugs after organ transplant

Dr. Samuel Strober is refining a process that eliminates the need for the many immunosuppresant drugs normally required after a transplant.

In 2019, there were over 23,000 kidney transplants in the United States, according to figures from the United Network for Organ Sharing (UNOS). These transplants can be lifesaving, but the donated organ can be perceived as a foreign invader by the patient’s immune system and attacked. In order to protect the organ from attack, transplant recipients are required to take numerous drugs that suppress the immune system, which are referred to as immunosupressive (IS) drugs. Unfortunately, these drugs, while helping protect the organ, can also cause long term problems such as hypertension, diabetes, heart disease, infection, a high concentration of fats in the blood, and cancer.

To address this problem, Dr. Samuel Strober and his team at Stanford University are conducting a CIRM-funded clinical trial that gives patients getting a kidney transplant a mixture of their own blood cells and cells from the kidney donor, a process called mixed chimerism.

Pairing patients and donors for transplants is done via Human Leukocyte Antigen (HLA) matching. HLA are markers on most cells in your body and are used by your immune system to recognize which cells belong to the body. If you are fully HLA matched that means your cells and the donor cells are immunologically compatible, and so less likely to be rejected. If they are HLA haplotypes, it means they are close but not fully matched so rejection is more likely.

In the trial, fifty-one patients with end stage renal failure that had just received a kidney transplant were infused with blood stem cells (cells that can give rise to different kind of blood cells) and T cells (a cell that plays a role in the immune response) obtained from the donor to achieve a mixed chimerism. Of the 51 patients 29 were fully HLA matched, and 22 were HLA haplotype matched.

Standard IS drugs were administered to all the patients after transplantation and the patients were monitored from six to twelve months to ensure there was no organ rejection or graft vs host disease (GVHD), a condition where donated blood stem cells attack the body.

After this period, the patients were taken off the IS drugs and the results of this trial are very promising. Twenty-four of the fully HLA matched patients with a persistent mixed chimerism for at least six months were able to stop taking the IS drugs without evidence of rejection for at least two years. Ten HLA haplotype matched patients with a persistent mixed chimerism for at least twelve months were able to stop taking some of the IS drugs without rejection.

This is encouraging news for patients undergoing any kind of transplant, leading to hope that one day all patients might be able to get a life-saving organ without having to take the IS drugs forever.

The full results of this study were published in Science Translational Medicine.

The Most Important Gift of All

There are many players who have a key role in helping make a stem cell therapy work. The scientists who develop the therapy, the medical team who deliver it and funders like CIRM who provide the money to make this all happen. But vital as they are, in some therapies there is another, even more important group; the people who donate life-saving organs and tissues for transplant and research.

Organ and tissue donation saves lives, increases knowledge of diseases, and allow for the development of novel medications to treat them. When individuals or their families authorize donation for transplant or medical research, they allow their loved ones to build a long-lasting legacy of hope that could not be accomplished in any other way.

Four of CIRM’s clinical trials involve organ donations – three kidney transplant programs (you can read about those here, here and here) and one targeting type 1 diabetes.

Dr. Nikole Neidlinger, the Chief Medical Officer with Donor Network West – the federally designated organ and tissue recovery organization for Northern California and Nevada – says it is important to recognize the critical contribution made in a time of grief and crisis by the families of deceased donors. 

“For many families who donate, a loved one has died, and they are in shock. Even so, they are willing to say yes to giving others a second chance at life and to help others to advance science. Without them, none of this would be possible. It’s the ultimate act of generosity and compassion.”

The latest CIRM-funded clinical trial involving donated tissue is with Dr. Peter Stock and his team at UCSF. They are working on a treatment for type 1 diabetes (T1D), where the body’s immune system destroys its own pancreatic beta cells. These cells are necessary to produce insulin, which regulates blood sugar levels in the body.

In the past people have tried transplanting beta cells, from donated pancreatic islets, into patients with type 1 diabetes to try and reverse the course of the disease. However, this requires islets from multiple donors and the shortage of organ and tissue donors makes this difficult to do.

Dr. Stock’s clinical trial at UCSF aims to address these limitations.  He is going to transplant both pancreatic islets and parathyroid glands, from the same donor, into T1 patients. It’s hoped this combination approach will increase beta cell survival, potentially boosting long-term insulin production and removing the need for multiple donors.  And because the transplant is placed in the patient’s forearm, it makes it easier to monitor the effectiveness and accessibility of the islet transplants. Of equal importance, the development of this site will facilitate the transplantation of stem cell derived beta cells, which are very close to clinical application.

“As a transplant surgeon, it is an absolute privilege to be able to witness the life-saving organ transplants made possible by the selfless generosity of the donor families. It is hard to imagine how families have the will to think about helping others at a time of their greatest grief. It is this willingness to help others that restores my faith in humanity”

Donor Network West plays a vital role in this process. In 2018 alone, the organization recovered 702 donor samples for research. Thanks to the generosity of the donors/donor families, the donor network has been able to provide parathyroid and pancreas tissue essential to make this clinical trial a success”

“One organ donor can save the lives of up to eight people and a tissue donor can heal more than 75 others,” says Dr. Neidlinger. “For families, the knowledge that they are transforming someone’s life, and possibly preventing another family from experiencing this same loss, can serve as a silver lining during their time of sorrow. .”

Organs that can be donated

Kidney (x2), Heart, Lungs (x2), Liver, Pancreas, Intestine

Tissue that can be donated

Corneas, Heart valves, Skin, Bone, Tendons, Cartilage, Veins

Currently, there are over 113,000 people in the U.S. waiting for an organ transplant, of which 84 % are in need of kidneys.  Sadly, 22 people die every day waiting for an organ transplant that does not come in time. The prospect of an effective treatment for type 1 diabetes means hope for thousands of people living with the chronic condition.

Rare Disease Gets Big Boost from California’s Stem Cell Agency

UC Irvine’s Dr. Leslie Thompson and patient advocate Frances Saldana after the CIRM Board vote to approve funding for Huntington’s disease

If you were looking for a poster child for an unmet medical need Huntington’s disease (HD) would be high on the list. It’s a devastating disease that attacks the brain, steadily destroying the ability to control body movement and speech. It impairs thinking and often leads to dementia. It’s always fatal and there are no treatments that can stop or reverse the course of the disease. Today the Board of the California Institute for Regenerative Medicine (CIRM) voted to support a project that shows promise in changing that.

The Board voted to approve $6 million to enable Dr. Leslie Thompson and her team at the University of California, Irvine to do the late stage testing needed to apply to the US Food and Drug Administration for permission to start a clinical trial in people. The therapy involves transplanting stem cells that have been turned into neural stem cells which secrete a molecule called brain-derived neurotrophic factor (BDNF), which has been shown to promote the growth and improve the function of brain cells. The goal is to slow down the progression of this debilitating disease.

“Huntington’s disease affects around 30,000 people in the US and children born to parents with HD have a 50/50 chance of getting the disease themselves,” says Dr. Maria T. Millan, the President and CEO of CIRM. “We have supported Dr. Thompson’s work for a number of years, reflecting our commitment to helping the best science advance, and are hopeful today’s vote will take it a crucial step closer to a clinical trial.”

Another project supported by CIRM at an earlier stage of research was also given funding for a clinical trial.

The Board approved almost $12 million to support a clinical trial to help people undergoing a kidney transplant. Right now, there are around 100,000 people in the US waiting to get a kidney transplant. Even those fortunate enough to get one face a lifetime on immunosuppressive drugs to stop the body rejecting the new organ, drugs that increase the risk for infection, heart disease and diabetes.  

Dr. Everett Meyer, and his team at Stanford University, will use a combination of healthy donor stem cells and the patient’s own regulatory T cells (Tregs), to train the patient’s immune system to accept the transplanted kidney and eliminate the need for immunosuppressive drugs.

The initial group targeted in this clinical trial are people with what are called HLA-mismatched kidneys. This is where the donor and recipient do not share the same human leukocyte antigens (HLAs), proteins located on the surface of immune cells and other cells in the body. Around 50 percent of patients with HLA-mismatched transplants experience rejection of the organ.

In his application Dr. Meyer said they have a simple goal: “The goal is “one kidney for life” off drugs with safety for all patients. The overall health status of patients off immunosuppressive drugs will improve due to reduction in side effects associated with these drugs, and due to reduced graft loss afforded by tolerance induction that will prevent chronic rejection.”

71 for Proposition 71

Proposition 71 is the state ballot initiative that created California’s Stem Cell Agency. This month, the Agency reached another milestone when the 71st clinical trial was initiated in the CIRM Alpha Stem Cell Clinics (ASCC) Network. The ASCC Network deploys specialized teams of doctors, nurses and laboratory technicians to conduct stem cell clinical trials at leading California Medical Centers.

StateClinics_Image_CMYK

These teams work with academic and industry partners to support patient-centered for over 40 distinct diseases including:

  • Amyotrophic Lateral Sclerosis (ALS)
  • Brain Injury & Stroke
  • Cancer at Multiple Sites
  • Diabetes Type 1
  • Eye Disease / Blindness Heart Failure
  • HIV / AIDS
  • Kidney Failure
  • Severe Combined Immunodeficiency (SCID)
  • Sickle Cell Anemia
  • Spinal Cord Injury

These clinical trials have treated over 400 patients and counting. The Alpha Stem Cell Clinics are part of CIRM’s Strategic Infrastructure. The Strategic Infrastructure program which was developed to support the growth of stem cell / regenerative medicine in California. A comprehensive update of CIRM’s Infrastructure Program was provided to our Board, the ICOC.

CIRM’s infrastructure catalyzes stem cell / regenerative medicine by providing resources to all qualified researchers and organizations requiring specialized expertise. For example, the Alpha Clinics Network is supporting clinical trials from around the world.

Many of these trials are sponsored by commercial companies that have no CIRM funding. To date, the ASCC Network has over $27 million in contracts with outside sponsors. These contracts serve to leverage CIRMs investment and provide the Network’s medical centers with a diverse portfolio of clinical trials to address patients’’ unmet medical needs.

Alpha Clinics – Key Performance Metrics

  • 70+ Clinical Trials
  • 400+ Patients Treated
  • 40+ Disease Indications
  • Over $27 million in contracts with commercial sponsors

The CIRM Alpha Stem Cell Clinics and broader Infrastructure Programs are supporting stem cell research and regenerative medicine at every level, from laboratory research to product manufacturing to delivery to patients. This infrastructure has emerged to make California the world leader in regenerative medicine. It all started because California’s residents supported a ballot measure and today we have 71 clinical trials for 71.

 

 

How CIRM support helped a promising approach to type 1 diabetes get vital financial backing

Death-Vallery-011

The “Valley of Death” sounds like a scary place from “Lord of the Rings” or “Game of Thrones” that our heroes have to navigate to reach safety. The reality is not that different. It’s the space that young companies have to navigate from having a good idea to getting financial backing, so they can move their projects towards the clinic. At the other side of the Valley are deep-pocket investors, waiting to see what makes it through before deciding if they want to support them.

It’s a Catch 22 situation. Without financing companies can’t make it through the Valley; but they need to get through before the folks with money will considering investing. As a result many companies languish or even fail to make it through the Valley of Death. Without that financial support promising therapies are lost before they even get a chance to show their potential.

CIRM was created, in part, to help those great ideas get through the Valley. That’s why it is so gratifying to hear the news today from ViaCyte – that is developing a promising approach to treating type 1 diabetes – that they have secured $80 million in additional financing.

The money comes from Bain Capital Life Sciences, TPG and RA Capital Management and several other investors. It’s important because it is a kind of vote of confidence in ViaCyte, suggesting these deep-pocket investors believe the company’s approach has real potential.

In a news release Adam Koppel, a Managing Director at Bain, said:

“ViaCyte is the clear leader in beta cell replacement, and we are excited about the lasting impact that it’s stem cell-derived therapies can potentially have on improving treatment and quality of life for people living with insulin-requiring diabetes. We look forward to partnering with ViaCyte’s management team to accelerate the development of ViaCyte’s transformative cell therapies to help patients.”

CIRM has been a big supporter of ViaCyte for several years, investing more than $70 million to help them develop a cell therapy that can be implanted under the skin that is capable of delivering insulin to people with type 1 diabetes when needed. The fact that these investors are now stepping up to help it progress suggests we are not alone in thinking this project has tremendous promise.

But ViaCyte is far from the only company that has benefitted from CIRM’s early and consistent support. This year alone CIRM-funded companies have raised more than $1.0 billion in funding from outside investors; a clear sign of validation not just for the companies and their therapies, but also for CIRM and its judgement.

This includes:

  • Humacyte raising $225 million for its program to help people battling kidney failure
  • Forty Seven Inc. raising $113 million from an Initial Public Offering for its programs targeting different forms of cancer
  • Nohla Therapeutics raising $56 million for its program treating acute myeloid leukemia

We have shown there is a path through the Valley of Death. We are hoping to lead many more companies through that in the coming years, so they can bring their therapies to people who really need them, the patients.

 

 

 

Stories that caught our eye: Is a Texas law opening up access to stem cell treatments working? Another CIRM-funded company gets good news from the FDA.

TexasCapitol_shutterstock_494317324

In 2017 Texas passed a sweeping new law, HB 810, which allowed medical clinics to provide “investigational stem cell treatments to patients with certain severe chronic diseases or terminal illnesses.” Those in favor of the law argued that patients battling life-threatening or life-changing diseases should have the right to try stem cell therapies that were involved in a clinical trial.

Now a new study, published in the journal Stem Cells and Development, looks at the impact of the law. The report says that despite some recent amendments t there are still some concerns about the law including:

  • It allows treatment only if the patient has a “severe, chronic” illness but doesn’t define what that means
  • It doesn’t have clearly defined procedures on tracking and reporting procedures so it’s hard to know how many patients might be treated and what the outcomes are
  • There is no Food and Drug Administration (FDA) oversight of the patients being treated
  • Because the treatments are unproven there are fears this will “open up the state to unsavory and predatory practices by individuals preying on vulnerable patients”

The researchers conclude:

“While HB 810 opens up access to patients, it also increases significant risks for their safety and financial cost for something that might have no positive impact on their disease. Truly understanding the impact of stem cell based interventions (SCBI) requires scientific rigor, and accurate outcome data reporting must be pursued to ensure the safety and efficacy behind such procedures. This information must be readily available so that patients can make informed decisions before electing to pursue such treatments. The creation of the SCBI registry could allow for some level of scientific rigor, provide a centralized data source, and offer the potential for better informed patient choices, and might be the best option for the state to help protect patients.”

Another CIRM-funded company gets RMAT designation

Poseida

When Congress approved the 21st Century Cures Act a few years ago one of the new programs it created was the Regenerative Medicine Advanced Therapy (RMAT) designation. This was given to therapies that are designed to treat a serious or life-threatening condition, where early clinical stage trials show the approach is safe and appears to be effective.

Getting an RMAT designation is a big deal. It means the company or researchers are able to apply for an expedited review by the FDA and could get approval for wider use.

This week Poseida Therapeutics was granted RMAT designation by the Food and drug Administration (FDA) for P-BCMA-101, its CAR-T therapy for relapsed/refractory multiple myeloma. This is currently in a Phase 1 clinical trial that CIRM is funding

In this trial Poseida’s technology takes an immunotherapy approach that uses the patient’s own engineered immune system T cells to seek and destroy cancerous myeloma cells.

In a news release Eric Ostertag, Poseida’s CEO, welcomed the news:

“Initial Phase 1 data presented at the CAR-TCR Summit earlier this year included encouraging response rates and safety data, including meaningful responses in a heavily pretreated population. We expect to have an additional data update by the end of the year and look forward to working closely with the FDA to expedite development of P-BCMA-101.”

This means that five CIRM-funded companies have now been granted RMAT designations:
