What’s Happening?

A new Breakthrough T1D publication lays out the first clear preclinical testing and manufacturing roadmap for getting islet cell therapies for type 1 diabetes (T1D) into human clinical trials faster.

What is This Publication About?

Before any new therapy—including islet cell therapies for T1D—can move into in-human clinical trials, they need to go through rigorous testing in labs to confirm that they are likely to work and be safe in people. These are called preclinical studies.

In addition, therapies or drugs that are made in large enough quantities to support clinical studies need to undergo thorough validation and quality control testing to ensure that every pill, cell, or injection a person receives meets certain quality standards.

That’s where this publication authored by Breakthrough T1D staff and collaborators comes in. Islet cell therapies manufactured in labs are already in clinical trials. With more on the way, researchers need to think about the best approaches to preclinical studies and manufacturing to accelerate these therapies as quickly as possible.

In other words, we need a lot more cells to study these therapies in a lot more people. This paper is the roadmap to do that efficiently.

This publication was spearheaded by Marjana Marinac, Pharm.D. (Associate Vice President of Regulatory Affairs) and Chanel Press, Ph.D. (Director of Regulatory Affairs), in addition to Esther Latres, Ph.D. (Senior Vice President of Research), Nicholas Mamrak, Ph.D. (Senior Scientist), and several expert collaborators across the field.

Why Does This Matter?

Manufactured islet cell therapies for T1D are still new. This publication takes general guidance from regulatory agencies like the U.S. Food and Drug Administration (FDA) and gives developers a roadmap for the types of studies, information, and data that regulators need to give the green light for clinical trials of manufactured islet cell therapies.

With a clear path to first-in-human studies, manufactured islet cell therapies can progress faster than ever. This is key to our Project ACT initiative to accelerate cell therapies on a large scale for anyone with T1D who wants them. This publication will help us get there.

What’s Next?

This paper will be presented as a poster at the International Society for Stem Cell Research 2026 Annual Meeting in Montreal, Canada, opening the doors to conversations with researchers in the field who can turn the roadmap into action. If you are attending, visit the poster during Poster Session 2 on Thursday, July 9, 2026, from 4:00 to 5:15 p.m.

In September, Breakthrough T1D and the National Institute of Diabetes and Digestive Diseases (NIDDK) are co-hosting a workshop that will bring together leaders from academia, industry, government, and the T1D community to discuss challenges and strategies around islet cell therapies, including manufacturing and nonclinical considerations. Learn more about the workshop and register today.

Islet cell therapies for type 1 diabetes (T1D) replace destroyed insulin-producing beta cells with functional cells that allow the body to make insulin again. To ensure there are enough islet cells for everyone with T1D who wants them, Breakthrough T1D is prioritizing manufactured cell therapies, which can be made in large quantities in a laboratory, adhering to high levels of quality control.

These therapies are quickly advancing through the drug development pipeline. How are we making sure the clinical community is prepared for their arrival?

The answer: Centers of Reference.

The second annual Centers of Reference meeting was held at Breakthrough T1D HQ in early May by our Medical Affairs team. Read on to learn more about the attendees, what the meeting covered, and what we can expect next year.

Assembling the team at Breakthrough T1D HQ

This meeting was hosted by Thomas Danne, M.D., Ph.D., Chief Medical Officer International, Brynn Marks, M.D., Senior Director of Medical Affairs, Alessandro Bisio, M.D., International Director of Medical Affairs, and Amara Ogbonnaya-Whittlesey, M.D., U.S. Director of Medical Affairs, who brought together the best and brightest minds who can make Centers of Reference a reality.

Physicians, transplant surgeons, nurses, scientists, and other HCPs from various global medical institutions were in attendance, coming from:

• University of Minnesota Medical Center
• University of Wisconsin Health Transplant Center
• The Penn Rodebaugh Diabetes Center
• University of Chicago Medicine
• IRCCS Ospedale San Raffaele (Italy)
• Institute of Transplantation, Newcastle upon Tyne (UK)
• Edmonton, University of Alberta (Canada)

Additional attendees from Breakthrough T1D included CEO Aaron Kowalski, Ph.D., Senior Vice President of Research Esther Latres, Ph.D., multiple members of our Medical Affairs and Advocacy teams, and two members of our Participant Advisory Council who are living with T1D.

Convening experts with the power to make real change

The objective of this meeting was to build on the progress that the working groups have made over the past year. Each group focuses on a key aspect of the development of Centers of Reference, taking a divide-and-conquer approach to capitalize on experts’ strengths and workshop ideas with the larger team.

We have learned recently that when a first-of-its-kind therapy comes to market, it isn’t magically going to be adopted by physicians and administered to people. There is a significant amount of prep work that has to happen to ensure that every connection is made so that these therapies, and ultimately people with T1D, succeed.

This meeting is that work, led by the leaders in the field.

Working group #1: HCP Training and Education

The group identified which topics around islet cell therapies should be included in educational programs for aspiring T1D medical professionals, including eligibility for islet cell therapies, the transplant procedure itself, post-transplant care, and long-term monitoring. Importantly, the ultimate career path of the trainee should play a factor in which topics require further education versus a brief overview. For example, a psychologist working with the T1D community may not have the same educational needs as a transplant surgeon, but both should understand T1D cell therapy basics.

Working group #2: Clinical Access to Cell Therapies

This group focused on how to best educate HCPs and people with T1D about emerging islet cell therapies. The team found that most people who receive cell therapies self-refer, but misconceptions are a major barrier to pursuing them. Priority areas for increasing awareness in the T1D community are communicating through social media, creating an easy-to-use landing page or website with information and opportunities to connect with medical teams, and connecting people with peers who have received islet cell transplants. In terms of HCPs, the group is focused on creating referral pathways, using artificial intelligence to help establish clinical workflows for islet cell transplants, and utilizing professional organizations to connect with and educate the T1D medical community.

Working group #3: Harmonizing Clinical Care

This group has one of the most challenging tasks: creating a roadmap for the clinical implementation of islet cell therapies. This includes determining eligibility based on defined clinical measures, reaching consensus on the best way to approach care before, during, and immediately after islet cell therapy, and consistent long-term monitoring. To add to the challenge, this roadmap must be applied across diverse clinical settings in different countries. The experts in the room—some of the most prominent T1D physicians and transplant surgeons in the world—made significant progress in defining clinical measures and tools that should be used in islet cell transplants.

Working group #4: Benchmarking and Center Readiness

Centers of Reference will be held to the highest standards to ensure they are providing top-quality clinical care to people receiving islet cell transplants. To make this possible, this group created a framework for assessing Center readiness, collaborating with registries for data-sharing, and benchmarking to evaluate Center effectiveness. This includes development of specific criteria laying out what each Center needs, such as a complete islet cell therapy care team, established processes for quality and safety, research teams, and more.

One theme was clear throughout nearly all of the working groups: incorporating the perspectives of people with T1D is absolutely critical. The groups agreed that clinical decision-making around islet cell therapies is about more than just someone’s blood sugar—the way a person feels, their level of diabetes distress, and their individual circumstances are key factors to integrate into shared decisions between people and their care teams.

Over the next 12 months, each team will follow up on the challenges, solutions, and immediate next steps identified during the meeting to keep progress moving. Thanks to everyone’s hard work over a productive and exciting two days, we are accelerating faster than ever toward the development of expert Centers of Reference.

What the experts are saying

“Cell therapies are getting closer and closer to reality, and our partners in the clinic must be ready to implement them. This is a good problem to have! We know that new therapies will take far too long to reach the people that need them if we don’t have an established clinical infrastructure. We have the best people in the world in the room, working through the problem with us, to ensure that when these therapies do become an approved therapy option, the T1D community can benefit as soon as possible.”

-Thomas Danne, M.D., Ph.D., Chief Medical Officer International at Breakthrough T1D

“Our hope is that Centers of Reference enable preparedness and expedite the delivery of new cell therapies—as they are approved—to become immediately accessible to people with T1D most in need of a novel intervention for the treatment of their diabetes.”

-Michael Rickels, M.D., M.S., Medical Director, Pancreatic Islet Cell Transplant Program, Hospital of the University of Pennsylvania

“Breakthrough T1D is proactively working now to identify and remove current and future barriers to T1D cell therapy coverage. By working with payers and policymakers now, we will accelerate broader access to T1D cell therapies.”

-Aaron Turner-Phifer, Senior Director of Health Policy at Breakthrough T1D

“Centers of Reference can help prepare healthcare systems around the globe for future cell therapies in T1D by building the expertise and standards needed to deliver them safely. They also help share experiences and best practices so more hospitals are ready to adopt these treatments over time.”

-Carmen Hurtado del Pozo, Ph.D., Director of European Research at Breakthrough T1D

Steady progress towards our goal

Manufactured islet cell therapies are coming. It is not a matter of if, but when. We are at a critical moment and need to ensure that HCPs are ready. Teamwork will get these therapies into clinics so people with T1D don’t have to wait years to get them.

This is why Breakthrough T1D is acting now: when the first manufactured islet cell therapy becomes commercially available, multidisciplinary care teams around the world will be prepared. This is essential to our Project ACT initiative, which is accelerating islet cell therapies that do not require immunosuppression for the T1D community.

Our goal is to advance islet cell transplants and establish Centers of Reference around the world, so that people anywhere can access these therapies as they become available. Centers of Reference are leading the way for safe and effective integration of manufactured cell therapies into clinics. These annual meetings provide a platform for international experts to connect and refine these Centers over two days of idea-sharing and collaboration. We’re already looking forward to seeing what the team will have accomplished by this time next year!

Here’s what you need to know about deceased donor islet cell transplants—and our plan to expand availability to them safely and responsibly. 

What Is Deceased Donor Islet Cell Transplantation? 

Deceased donor islet cell transplantation is a procedure in which insulin-producing islet cells are isolated from the pancreases of deceased donors and transplanted into a person living with type 1 diabetes (T1D). These islets are infused into the liver, where they can begin producing insulin in response to blood glucose levels.  

Deceased donor islet cell transplants are intended for, and only FDA-approved for, adults with T1D who experience: 

• Severe hypoglycemia (dangerous low blood sugar) 
• Hypoglycemia unawareness (the inability to sense when blood sugar is dropping)

These individuals often cannot safely manage their blood glucose levels with the standard therapies used to manage T1D, including continuous glucose monitors (CGMs) and automated insulin delivery (AID) systems. 

Do They Work?

Yes. For adults with T1D who experience severe hypoglycemia and hypoglycemia unawareness, deceased donor islet cell transplantation has been shown to significantly reduce—or even eliminate—the need to take external insulin.  

Do Deceased Donor Islet Cell Transplants Require Immunosuppression? 

Yes. Recipients of deceased donor islet cell transplants must take immunosuppressives to prevent the body from rejecting the transplanted cells. Due to the side effects of immunosuppressives, these transplants are only approved for adults whose risk from severe hypoglycemia outweighs the risks associated with immunosuppression. 

Breakthrough T1D is working on alternatives to traditional immunosuppression so more people can benefit. This includes our funding of the University of Chicago’s clinical trial with Eledon’s drug, tegoprubart.

Why Aren’t They Widely Available?

Deceased donor islet cells come from organ donors. A single transplant often requires multiple pancreases as isolating islet cells is a complicated process. In addition to those challenges, the availability in the U.S. is more limited than it is in other countries due to regulatory classification.  

The U.S. currently regulates deceased donor islet cells as biological drugs requiring a Biologics License Application (BLA). This is different from how whole organ transplants are regulated in the U.S. and how deceased donor islet cells are regulated in many other countries, including Canada, the United Kingdom and countries in the European Union.   

How Is Breakthrough T1D Advocating for Expanded Deceased Donor Islet Cell Transplant Availability?

Breakthrough T1D has strongly urged HHS to reclassify and expand availability of deceased donor islet cells. 

Our proposal outlines a framework to ensure safety and accessibility for the T1D community. You can read the letter here. 

We are putting 100% of our energy behind this approach, and we are doing it with the full support of leading transplant surgeons and organizations.  

Why Is Breakthrough T1D Pursuing This Route (HHS) as Opposed to Legislation (ISLET Act)?

This is our best chance of success. Passing legislation is extremely difficult at best, and HHS has existing authority over the regulatory framework governing cell therapies and organ transplantation. They can make this change. 

Additionally, the ISLET Act does not require the development of safety standards for reclassified deceased donor islet cell transplants, nor does it address insurance coverage, which could limit access to these costly treatments. 

What Are the Details of Breakthrough T1D’s Recommendations in the Letter to HHS?

Our proposal outlines a clear strategy to ensure the safety and quality of deceased donor islet cells under this reclassification. They include: 

• Designating Centers of Excellence staffed with experts in deceased donor islet cell transplants 
• Strict quality control to ensure islets are functional—and they work 
• A way to get cells from the deceased donors’ pancreases and into people with T1D
• A strategic roadmap for adding additional centers

Why Not Work with HHS and Support the ISLET Act? 

Our Breakthrough T1D legislative agenda includes several critical priorities essential to advancing our mission. This includes the ongoing renewal of the Special Diabetes Program (SDP) to fund T1D research and efforts to improve insulin affordability. These issues require legislative action, which is why we continue to focus our legislative advocacy on them. 

Not every priority is best achieved through Congress. Reclassifying deceased donor islet cells as organs, for example, can be accomplished under current law through the Department of Health and Human Services (HHS), without new legislation. This is one of the key reasons we believe the path through HHS is the best path for this issue. 

Simply put, we are pursuing each of our priorities through the channel where it has the greatest likelihood of success. And given how difficult it is to pass legislation, putting 100% of our effort toward working with HHS has the best chance of success.  

Why Doesn’t Breakthrough T1D Recommend an Amendment to the ISLET Act?

Given how difficult it is to pass legislation, we believe our effort to reclassify deceased donor islet cells as organs is much more likely to succeed focusing on HHS. 

What effect would this have on stem cell-derived islets?

Breakthrough T1D believes that stem cell-derived islets are appropriately regulated by FDA as biologic products. There is no need to change the regulatory status for manufactured islets. If adopted, our proposal would not affect them.  
 
Through Project ACT, Breakthrough T1D is working with all parties to clear the way for future, manufactured islet therapies and to ensure they are accessible. 

Q: Patti, can you tell us about your diabetes journey?

A: I was diagnosed with T1D in October 1986. I’ve lived with it for nearly 39 years. As anyone who knows this disease can tell you, it’s very hard. I’ve used every possible management system—pumps, continuous glucose monitors (CGMs), inhaled insulin, and I even have a diabetic alert dog named Otto. Despite these tools, I always struggled with low blood sugars, and I struggled with the mental burden of this disease. I was the kid at diabetes camp who had to get a glucagon injection in the middle of the night.

Q: What did you use to manage your T1D?

A: I’ve done everything—pumps, injections, CGMs, everything. But now I use multiple daily injections. I also rely on my diabetic alert dog—Otto! Otto, my service dog would often jump in my bed 20 minutes before a CGM would go off. And he consistently does that!

How did you hear about the clinical trial?

A: Having been around T1D for so long, I knew about the concept of islet transplants. I also knew that the end goal is making these cells. It was exciting but not something I thought was a reality today.

About two years ago, I heard about a clinical trial being done by Vertex. I found out about it on Instagram, actually. I then reached out to them and began the screening process.

Q: What was the screening process like?

A: The screening was extremely thorough. I answered a ton of questions about my insulin usage, diet, blood type, history of hypoglycemia, and more. I even had to prove I had had T1D for all these years. They tested me for autoantibodies. They tested me for seemingly everything!

Q: How did it feel to make it into the trial?

A: Clinical trials like this are important. Clinical trials have to happen. We can’t get a cure without them, so somebody has to step up. I am lucky enough that I can step up—and I’m so glad to. 

Why this matters

Breakthrough T1D extends a heartfelt thank you to Patti for courageously sharing her story with us so we can truly understand why the work we’re doing is critically important. If you choose to participate in a clinical trial, like Patti, you have the potential to provide transformative benefits to the entire T1D community by accelerating the pace of clinical research. Learn more about clinical trials and how you can get involved. If you’re interested in the zimislecel clinical trial, check out the trial sites and eligibility criteria.

To accelerate T1D cures faster than ever, Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) is simultaneously advancing research, development, regulatory policies, access, and adoption of manufactured islet therapies that do not require broad immunosuppression. We will not stop until these therapies are available to everyone with T1D who wants them—and clinical trial participants like Patti are getting us there faster.

We are well on our way to seeing manufactured cell therapies like zimislecel come to life. We owe a huge thank you to our supporters and the broader T1D community for inspiring us every day to keep pushing forward until functional cures for T1D are a reality.

The short version

Breakthrough T1D’s newest publication outlines what the future of beta cell replacement therapies looks like—and how we can make these therapies a reality for everyone with type 1 diabetes (T1D) who wants them through innovative clinical trial design and expanding the pool of eligible trial participants.

Breakthrough T1D, in collaboration with other leading experts in the field, recently published an article titled “Future Directions and Clinical Trial Considerations for Novel Islet β-Cell Replacement Therapies for Type 1 Diabetes” in the journal Diabetes. Breakthrough T1D Research and Advocacy staff who contributed to the publication include Sanjoy Dutta, Ph.D., Chief Scientific Officer, Esther Latres, Ph.D., Vice President of Research, and Marjana Marinac, Pharm.D., Associate Vice President of Regulatory Affairs.

Beta cell replacement therapies have the potential to cure type 1 diabetes (T1D) by removing the need for external insulin. While donor islet transplantation can result in insulin independence and results from early trials with manufactured islets are encouraging, people with T1D need better tools and therapies. This publication serves as a roadmap for the entire field—including researchers, product developers, industry, regulators, clinicians, and people with T1D—to address these needs and ensure that beta cell replacement therapies can get to people with T1D as quickly and safely as possible.

Read on to learn more about what the future of beta cell replacement therapies looks like.

Where we are now

People living with T1D depend on external insulin to manage their condition throughout their lives. Despite advancements in diabetes technology, such as continuous glucose monitors (CGMs) and automated insulin delivery (AID) systems, most people with T1D are unable to achieve blood sugar targets, rendering them at a higher risk for complications, reduced quality of life, and lower life expectancy.

 It’s simple: we need to do more for the T1D community.

One promising avenue to meet these needs is through cell replacement therapy. Lantidra®, the first FDA-approved donor-derived islet replacement therapy for T1D, has proven to be safe and effective in eliminating severe hypoglycemia, providing insulin independence, and improving quality of life. However, this therapy is limited to people with severe hypoglycemia and requires immunosuppression to prevent rejection of the transplanted cells, which can have side effects. Even more, these donor-derived islets are in limited supply.

Alternative beta cell replacement therapies are emerging—and we can no longer limit their development to people experiencing severe hypoglycemia.

Developing cell therapy strategies to meet unmet needs of the T1D population

Breakthrough T1D’s vision for the T1D community includes beta cell replacement therapies with no immunosuppression that are available to everyone who wants them. We are committed to making this a reality through our Project ACT (Accelerate Cell Therapies) initiative, which will accelerate the development of these therapies to achieve our vision as quickly as possible.

We are entering an exciting era of beta cell replacement. Emerging therapies are addressing challenges such as cell source and scalability, resulting in the development of islets derived from sources other than donors, including manufactured islets and porcine islets. Up-and-coming therapies are also testing different transplantation sites, methods of delivery, and cell protection strategies to prevent immune rejection with the fewest side effects possible (and ideally no immunosuppression). Learn more about what scientists are doing to optimize beta cell replacement therapies.

Breakthrough T1D’s continuous support of many of these therapies, such as Vertex’s manufactured islet therapy zimislecel, has been critical to accelerating them through the clinical pipeline. Explore emerging beta cell replacement therapies in clinical trials now—and see how Breakthrough T1D’s commitment to these therapies helped make this possible.

When successful, the advent of new, safe, scalable, and effective beta cell replacement therapies will provide the T1D community with options. As these therapies are moving their way through the pipeline, we need to ensure they are being studied in a broader T1D population who stand to benefit.

So, how do we make this happen?

The roadmap for emerging beta cell replacement therapies

Expanding the T1D population eligible for beta cell transplantation

Current trials testing beta cell therapies necessitating immunosuppression require participants to have elevated HbA1c levels and recurrent severe hypoglycemic events. This limits the pool of participants to people who meet the requirements and are most likely to benefit, given the side effects associated with chronic, broad immunosuppressants.

Clinical trials for emerging beta cell replacement therapies should broaden eligibility criteria so more people with T1D can participate—and experience the potential benefits. When designing new clinical trials, sponsors and regulators should consider including a broader range of HbA1c levels, clinically important or serious hypoglycemic events, and other complications.

Studies have found that the T1D community is generally open to beta cell replacement therapies as a potential solution to T1D, and people are willing to accept the associated risk versus benefit considerations for the possibility of becoming insulin independent. A Breakthrough T1D assessment also found that physicians are interested in recommending beta cell replacement therapies to people with T1D—especially if they don’t require immunosuppression.

“Clinical trials to support the development of islet cell replacement therapies need to evolve to include a broader representation of people living with T1D who could benefit from these novel therapies. This includes expanding the outcomes used to assess the benefits of cell replacement that reflect how people with T1D feel and function.”

Marjana Marinac, Pharm.D., Associate Vice President of Regulatory Affairs

Placing people with T1D at the center of clinical trial design

The outcomes used to assess the effectiveness of cell therapies currently in clinical trials, including those involving deceased donor islets, are acceptable for emerging beta cell replacement therapies. These include on-target HbA1c levels, absence of severe hypoglycemia, significant reduction or elimination of external insulin, and restoration of the body’s insulin production as measured by C-peptide.

Other endpoints that should be considered include CGM metric targets like time-in-range in addition to person-reported outcomes. Understanding how a beta cell therapy may affect a person’s health-related quality of life—such as diabetes distress, fear of hypoglycemia, or social and family dynamics—will be critically important for calculating the risk to benefit ratio of these therapies.

Read more about why person-reported outcomes are important for cell therapies.

“There are still significant unmet needs in the T1D community. Breakthrough T1D’s roadmap is supported by the assessment of clinically meaningful outcomes and driving research toward solutions that address key factors such as cell sources and protections strategies that will broaden the people with T1D who could benefit from emerging cell replacement therapies.”

Esther Latres, Ph.D., Vice President of Research

Innovative trial designs to accelerate development of cell therapies

Clinical trials for beta cell replacement therapies are generally based on a single-arm, open-label design—meaning there is no placebo group and both participants and researchers know which therapy is being administered. While this design can work for emerging beta cell therapies, single trials with multiple arms testing alternative transplant sites, immune protection strategies, or other methods have the potential to speed up the pace of development.

Similarly, adaptive trial designs use mid-trial interim analyses of study data to inform the remainder of the trial. This helps researchers learn what’s working (or not working) and adjust the design accordingly, with guidance from regulatory agencies, so the rest of the trial is a focused and efficient use of time and resources. Potential interim changes to trial design include reducing the number of participants required, eliminating doses, recruiting people who are most likely to benefit, or stopping the trial outright due to clear success or failure.

By applying guidance in therapeutic development and innovative trial designs to emerging beta cell replacement therapies, we can move early-stage trials along faster, thereby allowing regulators to make decisions sooner. To support quicker trials and reduce the possibility for delays, researchers, developers, and regulators around the world need to work together to achieve convergence on trial populations, endpoints, and innovative designs that will meet regional requirements.

Learning from past successes

People with T1D continue to live with unmet needs with still significant risk for long-term complications, and they need more therapeutic options. Right now, most clinical trials for beta cell replacement therapies requiring immunosuppression are limited to a small portion of the T1D population. This needs to change—especially given the potential for insulin independence. The T1D community must be put first when making decisions about beta cell replacement therapies, and Breakthrough T1D is making sure that this happens.

Adjusting how we approach clinical trials for emerging beta cell replacement therapies will be critical for ensuring we accelerate the research, development, regulatory approval, access and adoption of these novel therapies. Breakthrough T1D successfully accomplished this for AID systems—and we are confident that following a similar roadmap for cell therapies will get us to the finish line, faster.

Curative therapies for T1D are in reach. This roadmap, in conjunction with our Project ACT initiative, is key to bringing beta cell replacement therapies to every person with T1D who wants them.

To make this a reality, everyone needs to work together. As stated in the publication, “This requires a comprehensive strategy and a coordinated collaboration across stakeholders in every field relevant to islet cell replacement.” This roadmap is a guide for moving toward our common goal of a cure for T1D as soon as possible.

Breakthrough T1D will continue to lead the way until the T1D community can choose the beta cell replacement therapy that works best for them, regardless of blood glucose management or hypoglycemia status. Everyone deserves the chance to benefit.

We’ve made major progress in the development of cell replacement therapies for type 1 diabetes (T1D) over the past few decades. We know that manufactured islets can be safely implanted into people and produce insulin. Yet, there is more work to do to advance cell therapy research and bring these therapies to the larger T1D community. Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) will make manufactured cell replacement therapies that do not require broad immunosuppression a reality, faster.

The Breakthrough T1D x Stem Cell Network Partnership

To drive innovation in manufactured islet therapies, Breakthrough T1D, Breakthrough T1D Canada, and the Stem Cell Network (SCN) have partnered to support four new projects led by Canadian researchers. The organizations issued a joint Request for Applications and together will maximize resources to drive high-impact research into manufactured cells. This partnership is a novel and meaningful part of Breakthrough T1D’s global Project ACT effort to power high-impact cell therapies research.

“Accelerating cell therapies is a central focus of Breakthrough T1D’s research strategy to drive toward cures for type 1 diabetes,” said Breakthrough T1D Vice President of Research Esther Latres, Ph.D. “We’re excited to join Stem Cell Network and Breakthrough T1D Canada in funding these outstanding cell therapy researchers and projects that can build on the current momentum to overcome barriers and advance cell therapies that can benefit all those who live with type 1 diabetes.”

These projects will receive support from May 2025 to April 2027. They are a part of a broader SCN investment totaling more than $33 million to support 36 regenerative medicine research projects and clinical trials.

Read on to learn more about the exciting, newly funded projects.

 A closer look at the projects

Current cell therapies for T1D, while often effective, are hampered by reliance upon donor-derived cells and poor cell survival after transplant, necessitating large doses of cells and repeat procedures.  This ambitious new project will address both the source of islet cells and the low cell survival rates associated with islet transplantation by accelerating Lunar Therapeutics’ preclinical development of a manufactured islet replacement product. Takebe’s lab describes it as “complex miniature organs” for T1D.  

This product will consist not only of insulin-producing cells, but also endothelial cells, which line blood vessels. Endothelial cells will support islet cell survival and engraftment upon transplantation.  

Organoid

An organoid is a three-dimensional tissue grown in the lab that resembles an organ.

To accomplish this objective, Lunar Therapeutics will bring together Canadian expertise in manufactured islets and clinical islet transplantation led by Drs. Timothy Kieffer and James Shapiro. The team will also include U.S.-based Dr. Takanori Takebe, who specializes in designing complex organoids composed of various cell types. Using technologies developed across each laboratory, this multidisciplinary team will work to address challenges in islet cell transplantation.  

The implantation of manufactured islets into people with T1D can restore insulin production, eliminating the for external insulin and improving quality of life. However, after islet cells are derived from donors or manufactured in the lab, they must be stored before being used to treat a person with T1D. Currently, the storage and transportation of islet cells is difficult, and the only storage method is freezing at low temperatures in the presence of chemical solutions that help with the freezing process. However, these solutions cause cell death during thawing and may also cause allergic reactions in people after transplantation.   

This project will address this gap in the field by aiming to develop non-toxic, naturally derived gels to optimize islet freezing and storage. The gel-based products will be evaluated for large-scale commercial production. The success of this project will provide new intellectual property that will be of interest to researchers and companies in regenerative medicine in Canada and across the globe. 

Manufactured islets offer a potentially unlimited source of islets for transplantation. Since manufactured islets carry unique risks compared to donor-derived islets, containment within a device could allow retrieval if off-target growth ever occurs. However, encapsulation devices that have been tested in clinical trials so far and have shown minimal success, mainly because blood supply to the cells is limited by the device barrier. In this project, the team proposes to develop a device where the manufactured islets are placed around pre-established vessels that can improve islet cell survival and speed of insulin responses via improved blood supply. In this project, they will optimize their device design and conduct advanced preclinical studies. 
 
This project could lead to better survival and function of manufactured islets, so they can keep producing insulin. The project may also pave the way for other engineered human-scale encapsulation devices, also sometimes called bioartificial organs.

There are many new treatments on the horizon for T1D, including those that block autoimmunity or replace insulin-producing cells. However, a major barrier to these therapies is the lack of an easy-to-use model in which their effects on human cells can be tested before advancing to human trials. The standard preclinical model is to test therapies in small animal models of T1D, but this has significant limitations since it is nearly impossible to replicate the human immune system. In fact, diabetes has been “cured” hundreds of times in a mouse model, which has not translated to humans. 
 
To overcome this barrier, Dr. Levings and her team will establish a new a model that recreates human T1D autoimmunity in the lab. The model will use manufactured cells to create the three types of cells that are involved in the disease: insulin-producing cells and two different types of immune cells. Using the model, cells can then be combined in different ways to recreate what usually happens during autoimmunity. 
 
A model of human T1D that can be generated in the lab will help test potential treatments and prompt new questions about why T1D develops, and how to prevent it. Thus, this research has the potential to support the further development of innovative therapies that may offer new approaches to prevent or treat people with T1D. 

Putting it all together

Curing T1D is the north star of Breakthrough T1D. These partnerships will help us work together toward our shared goal of a world without T1D—through innovation, forward-thinking cell therapy research, and the best and brightest scientists.

Project ACT series

This article is the last part of a series exploring the different ways that Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) is shaping the future of cell therapies for type 1 diabetes (T1D).

Read last month’s article about the role of Advocacy in cell therapies for T1D.

Cell therapies, which place insulin-producing cells back into the bodies of people with T1D, are making major headway in clinical trials—and people are becoming insulin independent. In past installments of this article series, we’ve explored how we got to this point at every step in the pipeline: from advocating for funding, to conducting research in laboratories, to clinical testing in humans, and to working with regulators and insurers.

But we’re not at the finish line yet. Approval of manufactured cell therapies isn’t enough to make sure that people who want these cells can get them. So, how do we fill this gap?

Medical Affairs is the backbone of clinical adoption

The answer is Medical Affairs—Breakthrough T1D’s newest mission pillar—which aims to support the clinical adoption of manufactured cell therapies. As we are soon approaching the regulatory submission of a first-generation manufactured cell therapy, Medical Affairs initiatives will be especially important in making sure that healthcare professionals (HCPs) have the tools they need to bring these therapies to clinics. By partnering with global experts and HCPs to increase knowledge and clinical competencies, the Medical Affairs team is working to ensure the future delivery of manufactured cell therapies to eligible people with T1D.

Learn more about why Medical Affairs is important for every treatment, therapy, drug, and device for T1D.

Preparation is key

Since manufactured cell therapies for T1D are not yet FDA-approved, we are at a critical moment where preparation is essential. This is why the Medical Affairs team is planning now for the eventual arrival of first-generation manufactured cell therapies. They are partnering with advanced clinical teams to determine best practices to ensure that clinics have the right resources and skillsets. They are anticipating obstacles—and finding solutions—to the adoption of manufactured cell therapies. Then, when these therapies become available, HCPs will be ready and waiting to deliver them to people with T1D.

Assembling expert clinical teams and facilities

For people with T1D to have access to manufactured cell therapies, comprehensive expert clinical care teams need to be at the ready. To make this possible, we are starting at the very beginning: in training programs.

New, updated programs and fellowships must incorporate specialized education around cell therapies (such as optimized immunosuppression regimens and pre- and post-transplant education) for the next generation of HCPs. At a time when there are too few endocrinologists and certified diabetes care and education specialists, there’s no better time than now to encourage trainees to enter the field. We need to ensure that T1D care teams have trained professionals who are up to pace with the newest cell therapy protocols.

In line with these efforts, the Medical Affairs team is also working to recognize expert multidisciplinary Centers of Reference, which are a network of T1D treatment centers that have the personnel, resources, facilities, and skills to deliver manufactured cell therapies to people with T1D with a consistent approach. These centers will act as training hubs and share outcomes to continuously improve and establish best practices as manufactured cell therapies are incorporated into clinics.

Guidelines, statements, workshops, and more

The Medical Affairs team is working with experts in the field on publications that will guide care teams to further support the standardized integration of manufactured cell therapies into clinical practice.

Clinical guidelines

Clinical guidelines are recommendations for clinicians about how to care for people with T1D. They are informed by a systemic review of evidence by experts to assess benefits versus risk of care options.

Consensus statements

Consensus statements are collective opinions of an expert panel representing the multidisciplinary care team and voice of people with T1D. These statements are developed when evidence is still being gathered.

To drive these efforts, the Medical Affairs team hosts workshops, convening international experts to collaborate and discuss ideas. Using established methodologies, these projects ensure that the final document reflects expert consensus. One of the latest workshops assembled islet cell transplantation professionals from around the world to begin developing a consensus on the clinical roadmap of cell replacement therapies—the first step of many toward clinical adoption.

Read more about the most recent Medical Affairs workshops, including one geared toward creating Centers of Reference. See a recent example of clinical guidelines for monitoring early-stage T1D.

Opportunities to learn

Through decades of research, we’ve learned a lot about T1D—and the newest therapies and treatments are as innovative and complex as ever. To keep up with the rapidly changing pace of innovation, the Medical Affairs team has put together opportunities for HCPs learn about cutting-edge advancements.

These HCP resources offer accredited, free, live or on-demand education around the latest T1D research. There is also information on upcoming conferences, published guidelines, and clinical trial opportunities, in addition to an email newsletter with regular updates. Accredited HCP education is essential to ensure that clinicians have the most up-to-date knowledge that they can share with the T1D community—an important step in clinical adoption. Cell therapy resources are currently under development and expected in the next year.

Clinical trial education and awareness

Clinical trials are a key step in ensuring that new and effective T1D treatments and cures, including manufactured cell therapies, can safely make their way to the T1D community. The Medical Affairs team is working to foster a culture of research participation by ensuring that HCPs have access to information on current clinical trials and can help to educate the T1D community on their importance.

The ultimate goal is to increase awareness about clinical trial opportunities and support shared decision-making between people with T1D and their diabetes care team about clinical trial participation. The bottom line? HCPs and the T1D community must be equipped with information to enable them to make informed choices about participating in cell therapy clinical trials.  

Medical Affairs help turn groundbreaking science into real care—by supporting doctors, educating communities, and making sure cell therapies for type 1 diabetes reach the people who need them most.”

Thomas Danne, M.D., Ph.D. Chief Medical Officer, Global

The bigger picture: Project ACT across the pipeline

In this series, we’ve explored how manufactured cell therapies are moving through every step of the pipeline. We took a deep dive into the challenges that researchers are addressing to optimize manufactured cells. We surveyed the different cell therapies that are in currently clinical testing. We reviewed how advocacy shapes funding, regulatory decisions, and access to cell therapies. Finally, we considered how to ensure the clinical adoption of manufactured cell therapies.

This is where Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) comes in. The ultimate goal is to accelerate manufactured cell therapies that do not require immunosuppression—all the way from the first discovery research in the lab to the adoption of cell therapies in clinics.

At every step of the way, we are moving cell therapies through the pipeline as fast as possible. Breakthrough T1D is preparing for the day when first generation manufactured cell therapies are available, and we are working toward a future with next generations of therapies that do not require immunosuppression. Thanks to concerted efforts by Breakthrough T1D’s Research, Advocacy, and Medical Affairs teams, each day we move closer to manufactured cell therapies becoming a reality for everyone with T1D.

A meeting of the minds

This past week, Breakthrough T1D helped organize an event hosted by Member of European Parliament Tomislav Sokol, Ph.D., titled “Accelerating Breakthroughs to Address Unmet Needs in Type 1 Diabetes.” This meeting, a significant coming-together of Breakthrough T1D and European policymakers, focused on the role of the EU in addressing the needs of the T1D community and accelerating T1D breakthroughs.

The purpose of this meeting was to raise awareness of T1D and the urgent need for the accelerated development and approval of breakthrough therapies in the EU. Conversations between Breakthrough T1D and European policymakers homed in on barriers and opportunities to advancing cures—including cell therapies and disease-modifying therapies—in the EU to get them into the hands of people with T1D, faster. This was an important step in establishing an open dialogue between Breakthrough T1D and the EU Institutions about working together to address T1D globally.

“This event in the EU Parliament allows us to engage with important decision-makers to ensure that the research and policy environments are oriented in a way to accelerate development of T1D breakthrough therapies in the EU as we also do in other countries,” explained Campbell Hutton, Senior Vice President of Global Advocacy at Breakthrough T1D.

Driving toward T1D cures in the EU and beyond

T1D is on the rise around the world, including in Europe. Recent publications by Breakthrough T1D staff and leadership brought attention to the rise in incidence and global T1D burden. We need to act now in conjunction with governments around the world—like the EU—to address the unmet needs of everyone around the world affected by T1D.

T1D cures, including cell therapies, are advancing through the clinical pipeline. Bringing awareness of T1D to the forefront—and educating key people on the progress we’re making toward cures—will be incredibly important for driving T1D research forward in the EU. This represents a critical opportunity for the EU to accelerate cell therapies faster than ever. As a global organization, Breakthrough T1D is collaborating with the EU government to help make this possible.

As the largest global funder of T1D research, Breakthrough T1D has provided funding to researchers across the world in addition to the EU. Right now, Breakthrough T1D is supporting €56 million in European initiatives, including 31 clinical trials—representing 19% of our funded research (including the U.K.). Breakthrough T1D has expert teams in research, medical, regulatory, and advocacy in Europe, meaning we are uniquely positioned to provide guidance on how the EU can strengthen its T1D efforts and collaborate on a global scale to drive T1D breakthroughs, especially in cell therapies.

Type 1 diabetes is a critical disease in Europe, and I was pleased to host an event for the T1D community and my colleagues in the European Parliament to learn about the unmet needs in T1D and how we can work together to accelerate breakthrough therapies in Europe to address those needs.”

Tomislav Sokol, Ph.D. Member of the European Parliament

What Breakthrough T1D leadership is saying

“This meeting is critically important to bringing the unmet needs of the T1D community into the spotlight in the EU. Global advocacy for curative T1D research is essential to achieving Breakthrough T1D’s mission, and continued collaboration with EU policymakers will get us there faster.”

Accelerating global action is paramount to our mission

Global problems require global solutions. This meeting served as a critical launching point for a continued partnership with the EU to fill gaps and address unmet needs for the T1D community. Building relationships and fostering long-term partnerships is critically important for reaching our common goal of bringing cures to people with T1D as soon as possible.

These important conversations between Breakthrough T1D and the EU government align with our Project ACT (Accelerate Cell Therapies) initiative to accelerate the development of cell therapies that do not require immunosuppression—for everyone with T1D in every country. In addition, through international Centers of Reference, Breakthrough T1D’s Medical Affairs team is developing expert clinical care centers that will be trained and ready to provide cell therapies to people with T1D once they become available. We are at the forefront of global action to prepare the world for curative cell therapies.

We are driving toward a future in which everyone with T1D—no matter where they are—has access to therapies, treatments, and care, bringing us closer to achieving our mission of a world without T1D. The more people we have working toward our mission, the faster we will get there.

Project ACT series

This article is part of a series exploring the different ways that Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) is shaping the future of cell therapies for type 1 diabetes (T1D). The next and final article in the series will focus on how Breakthrough T1D’s Medical Affairs team is working to bridge the gap between access to and adoption of cell therapies.

Read last month’s article about cell therapies for type 1 diabetes in clinical trials.

Right now, promising new manufactured cell therapies for type 1 diabetes are making their way to and through the clinical pipeline. Testing cell therapies in clinical trials helps us understand if they are safe and effective, and the data from these trials is ultimately used in decisions about whether a therapy should be approved and covered by insurers. From basic research to clinical trials, and from regulatory approval to access in the clinic, bringing cell replacement therapies to people with T1D as quickly as possible requires consistent advocacy and clear, thoughtful, and efficient policies from beginning to end.

Advocacy takes teamwork

This is where Breakthrough T1D’s Advocacy team comes in. They work on both sides of product approval—before and after—advocating for funding and policies that support research, development, approval, and access. This includes educating key players on the latest T1D science, modernizing and expanding approaches to manufactured cell therapy clinical trials, and working with payers to ensure access through insurance.

The ultimate goal is to work together—regulators, researchers, clinicians, policymakers, people with T1D, insurers, and industry—to accelerate the development and approval of manufactured cell replacement therapies, especially those that do not require broad immunosuppression. Breakthrough T1D’s Project ACT (Accelerate Cell Therapies) will make this a reality faster.

Read on to learn about the key areas towards which Breakthrough T1D’s Advocacy team is working to advance manufactured cell replacement therapies.

Advocating for funding and policies supporting cell therapy research

To ensure that there is government funding to support T1D research—including manufactured cell therapies—Breakthrough T1D’s Advocacy team regularly engages with policymakers in Washington, D.C. Importantly, we advocate for continuous renewal of the Special Diabetes Program (SDP), a federally funded initiative that contributes to T1D research at the National Institutes of Health (NIH). This funding is a critical accelerator of manufactured cell therapies research.

Through other initiatives, such as Government Day and Children’s Congress, we convene advocates of all ages in Washington, D.C. to share the impact of life with T1D and research updates with Members of Congress. This work includes hundreds of meetings with Members of Congress and their staff each year and engagement with the Diabetes Caucus in the House and Senate. These lawmakers play major roles in making decisions about government policies and funding. Engaging with them about the realities of T1D and the importance of research into potential cures like manufactured cell therapies is essential to ensuring the continuity of government funding that keeps this critical research going.

Ensuring that manufactured cells are safe—and that there are enough for everyone

Before manufactured cell therapies can be put into people, researchers use animal models to study the safety of a new therapy and determine whether it has the potential to work in humans. This can be a time-consuming and costly process. Breakthrough T1D is developing a roadmap for researchers, encouraging focus on the most critical challenges for manufactured cell therapies. The goal is to expedite these studies and get manufactured cells into people faster.

Another critical step is how the cells are made and making sure there are enough manufactured cells for everyone. The challenge is finding the best way to manufacture islets in large quantities while keeping them safe and functional. Breakthrough T1D is partnering with the best and brightest scientists at the Advanced Regenerative Medicine Institute and the Cedars-Sinai Biomanufacturing Institute to make this possible.

Understanding risks and benefits from the perspectives of people with T1D

For decision-makers—which includes regulators that approve products, health insurers, and policymakers—to make the best recommendations possible about manufactured cell therapies, they must consider the perspectives of people living with T1D. Importantly, this includes what risks someone with T1D is willing to accept for the possibility of curing T1D. This is especially important considering the significant unmet needs that remain for the T1D community, which are not always well understood by policymakers who are removed from the daily realities of living with T1D.

As a new kind of therapy, the way we think about the clinical studies that test cell replacement therapies needs to change. Clinical trials up to this point have only included a small subset of the T1D population, but as we have gained more experience with these therapies, we’ve learned that the trials should include as many people with T1D who could benefit as possible. This is especially important given the great potential of manufactured cell therapies to cure T1D. Further, how we measure benefits in clinical trials needs to expand to better consider the perspectives of people who will receive these treatments.

Breakthrough T1D is spearheading a Patient Preference Study to better understand and quantify how people living with T1D consider tradeoffs between risks and benefits when deciding whether to receive a manufactured cell transplant. This involves gathering perspectives from both people with T1D and their caregivers to understand how they view different aspects of cell replacement therapies that may influence their willingness to try it. The results, expected in fiscal year 2026, can be shared with regulators and policymakers to incorporate into their decisions regarding manufactured cell therapies for type 1 diabetes.

Educating insurers and advocating for access

Once a manufactured cell therapy becomes approved, the next challenge to tackle is access through insurance. To achieve our vision, people must have affordable insurance coverage of manufactured cell therapies, and ideally people should be able to choose between multiple cell therapy options. Our Advocacy team is already engaging with insurers and government payers to make them aware of manufactured cell therapy research progress for T1D. We are working toward establishing the pathway to coverage for these therapies.

To support these efforts, Breakthrough T1D uses data-driven approaches. For example, a recent study determined key demographics and the health insurance status of the T1D population. Our Advocacy team is using this data to better understand the population that can benefit from manufactured cell therapies. Through continued data collection and analyses, we can further advance the pathway to coverage for manufactured cell therapies.

Advancing progress through Project ACT

Breakthrough T1D is working with stakeholders across the entire T1D spectrum—from researchers, to regulators, to payers, to clinicians, to people with T1D—to ensure that progress is moving along quickly and efficiently for new cell therapies for type 1 diabetes. These efforts are based on a model that has already proven successful, leading to the development and adoption of Artificial Pancreas systems.

With the launch of Project ACT, every day we move closer to our goal of manufactured cell therapies becoming a reality for everyone with T1D.

Breakthrough T1D’s Advocacy team regularly engages in conversations with decision-makers who play a major role in influencing when, and if, manufactured cell therapies will become available to people with T1D. Breakthrough T1D is bringing the T1D community into the conversation, changing the way we think about clinical trials, and opening the doors of manufactured cell therapies to as many people with T1D as possible.

More manufactured cells, faster clinical trials, accessible therapies—we are identifying challenges, working together to tackle them, and accelerating manufactured cell therapies for type 1 diabetes faster than ever.
