Type 1 Diabetes
OpenSafe, durable insulin independence in people with established Type 1 Diabetes, without broad lifelong immunosuppression.
What “cured” would have to mean
Durable insulin independence with normal glycemia and no ongoing systemic immunosuppression, documented over long follow-up.

Readiness gates
- PASSG1 Program status is current. 0 overdue status entries and 0 unflagged inactive mentions in the endocrinology dossier.
- PASSG2 At least 10 verified sources. 21 PubMed-verified ledger claims.
- PASSG3 Trials mapped to tracks. 2755 of 2898 trials (95.1%) fall in a track (needs 90%); 13.6% sit only in the not-yet-classified track (needs 30% or less).
- PASSG4 Outcome ladder defined. 8 rungs, 5 counted automatically from registered outcomes.
- PASSG5 Contribution work exists. 927 completed trials past 18 months with no posted results (results-gap queue).
- PASSG6 Copy is honest. No cure claims and no em dashes in module text.
Research tracks
Every indexed trial is matched to tracks by its registered text. A trial can sit in several tracks; 395 (13.6%) are not yet classified.
