The cure watch

The race to cure type 1 diabetes, tracked in one place.

Every serious program working toward a functional cure or disease modification, from stem cell-derived islets to immune protection and gene therapy. Each one is evidence-labeled and linked to its live clinical trial status, so you can tell real progress from a press release.

8 programs tracked4 live trial recordsUpdated Jun 11, 2026

These are research programs pursuing a functional cure or disease modification for type 1 diabetes. None is a confirmed, broadly available cure. Trial status is informational, not medical advice, and not a recruiting offer. Verify eligibility and details with the official trial record and a clinician.

Teplizumab (Tzield)

Sanofi (developed by Provention Bio) · Anti-CD3 immunotherapy that delays onset

An infused antibody that quiets the immune attack on insulin-producing cells. It is FDA-approved to delay the onset of Stage 3 (clinical) type 1 diabetes in eligible at-risk people who are already in Stage 2.

Cell Pouch islet transplant

Sernova · Implantable bio-hybrid organ

An implanted 'Cell Pouch' is allowed to grow its own blood supply, then donor islet cells are placed inside it to produce insulin in a protected, vascularized site.

Phase
PHASE1, PHASE2
Immunosuppression
Currently used with immunosuppression
Clinical trialclinical trial

Tegoprubart (immune protection)

Eledon Pharmaceuticals · Anti-CD40L immune modulation for transplants

An antibody that calms a specific immune signal (CD40 ligand), studied as a gentler way to protect transplanted islet cells than today's standard immune-suppressing regimens.

Phase
Clinical trial
Immunosuppression
Aims to replace standard immunosuppression
RECRUITINGclinical trialRecruiting

Zimislecel (VX-880)

Vertex Pharmaceuticals · Stem cell-derived islet cell therapy

Fully differentiated, insulin-producing islet cells made from stem cells are infused into the liver's portal vein. Because the cells are donor-derived, recipients take immune-suppressing medicine to protect them.

Phase
PHASE3
Immunosuppression
Requires chronic immunosuppression
ACTIVE NOT RECRUITINGclinical trialRecruiting

VX-264 (encapsulated islet cells)

Vertex Pharmaceuticals · Encapsulated stem cell-derived islet cells

The same stem cell-derived islet cells are placed inside a small implantable device intended to shield them from the immune system, with the goal of avoiding immune-suppressing drugs entirely.

Phase
PHASE1, PHASE2
Immunosuppression
Designed to avoid immunosuppression

Gene-edited cell replacement

CRISPR Therapeutics · Gene-edited immune-evasive cells

Uses gene editing to create insulin-producing cells engineered to hide from the immune system, with the goal of transplanting them without immune-suppressing drugs.

Hypoimmune islet cells (UP421 / SC451)

Sana Biotechnology · Gene-engineered immune-evasive islet cells

Islet cells are genetically engineered to evade the immune system (a 'hypoimmune' design), aiming to transplant them without immune-suppressing drugs. SC451 extends the idea to stem cell-derived islets.

Phase

KRIYA-839 gene therapy

Kriya Therapeutics · One-time gene therapy

A gene therapy program aiming to restore insulin production or immune balance through a single treatment. Still in preclinical development.
