Project ACT: Accelerating cell therapies today for cures tomorrow

Cell therapies have the potential to transform the lives of people with type 1 diabetes (T1D) by replacing lost beta cells and ending the need for insulin injections. With Project ACT, Breakthrough T1D is fast-tracking these life-changing treatments, turning tomorrow’s cures into today’s reality.

Breakthrough T1D’s mission is clear: we’re here to improve lives today and tomorrow by accelerating life-changing breakthroughs to treat, prevent and, ultimately cure type 1 diabetes (T1D) and its complications. We have a clear strategy of how to achieve that mission. New cure and beta cell therapies are moving at pace and are closer to being available to people living with T1D than ever before.

Our bold vision includes transforming the future with cell therapies, and Project ACT is our how we plan to make that vision real for millions.

What is Project ACT?

Project Accelerating Cell Therapies (Project ACT), is a focused initiative to dramatically speed up cell therapy treatments as cures for T1D.

Project ACT will use Breakthrough T1D’s decades of research experience and strong global partnerships to speed up the development, approval, and use of cell therapies for type 1 diabetes that don’t require long-term immune-suppressing drugs.

What are cell therapies? 

T1D develops when the immune system destroys the body’s own insulin-producing beta cells until a person can no longer make enough insulin to keep their blood glucose in a safe range. At this point, a person would need to start injecting insulin to help regulate their blood sugar levels.  

Cell therapies aim to restore insulin production by implanting new beta cells, often derived from lab-grown cells. Some early trials are already underway in people, suggesting that these cells could be effective in treating T1D. The next step is to find ways to keep these new beta cells safe in the body without using drugs that have serious side effects. We’re working on this in several ways, including placing them inside a protective barrier or modifying the cells so they are undetected by the immune system. 

By replacing the beta cells destroyed by T1D, cell therapies offer a pathway to freedom from injecting insulin. Project ACT aims to accelerate these solutions and deliver them to those who need them most.

How Project ACT works

Cell therapies could represent a cure for many people with T1D by replacing lost beta cells. Project ACT provides the roadmap to accelerate this, via:

Research  

  • Supporting large-scale production of manufactured beta cells for researchers worldwide
  • Funding innovative research to protect manufactured beta cells from immune destruction

Advocacy  

  • Developing regulatory pathways for cell therapies
  • Securing ongoing government funding for this work
  • Engaging regulators and policymakers
  • De-risk Influence and de-risk regulatory pathways to further accelerate approvals for cell therapies

Medical Affairs 

  • Equipping healthcare professionals with the latest research and educational resources
  • Supporting implementation and adoption of approved therapies

Project ACT: Generational Roadmap 

Our priority is to bring the first-generation of cell therapies to market, so we can build the evidence needed to bring forward even better treatment options in the future.  

In the context of medication, ‘generation’ refers to the order in which different types of the same treatment are developed. As our understanding of T1D improves, researchers are continually developing newer, more advanced treatments. The different treatment generations reflect the continuous progress in understanding T1D and creating more effective and targeted treatments.

Why trust Breakthrough T1D?

We have a track record of bringing better treatments to our community: 

  • Nearly 20 years ago, our Hybrid Closed Loop Project (also known as an artificial pancreases) helped pioneer automated insulin delivery systems, now used by hundreds of thousands of people with T1D 
  • Over 25 years, we’ve invested over £180 million and funded more than 300 cell therapy research projects. In 2024 alone we activated over 30 grants to continue this research 
  • Our funding helped launch drugs like teplizumab, the first disease-modifying therapy to delay T1D 
  • One of the most promising therapies to restore insulin production in people with T1D, zimislecel, was made possible by Breakthrough T1D’s early support, starting with Professor Doug Melton in 2004 

We have the experience, the track record, the partners, and the drive to deliver real cures, fast.

Accelerating progress

Thanks to your support we have already:   

  • Opened two manufacturing facilities for beta cell production and testing at Cedar Sinai and the Advanced Regenerative Manufacturing Institute (ARMI) in New Hampshire, US 
  • Funded initiatives to test novel methods to enhance cell transplants; explore the factors driving success in clinical cell transplantation and leverage AI-driven approaches to accelerate next-generation cell therapy development 
  • Launched the development of two free courses on cell therapies and cell therapy clinical trials for T1D, aimed multidisciplinary healthcare professionals 
  • Begun educating policymakers and other key government stakeholders about Project ACT 
  • Submitted our Clinical Trials Roadmap perspectives piece for publication and sharing with key stakeholders, including regulators and researchers from academia and industry 

Join Us 

Through Project ACT, we will continue to advance our partnerships across industry, academia, government and the NHS, while mobilising other donors to join us as we transform the future of T1D.
