BREAKING: Kyverna Therapeutics ($KYTX) has officially initiated a rolling BLA submission to the FDA for miv-cel (mivocabtagene autoleucel), positioned to be the world’s first approved CAR-T for autoimmune disease.
The application targets Stiff-Person Syndrome (SPS), a rare neurological disorder with zero approved therapies. Crucially, the FDA has agreed that data from a single-arm Phase 2 trial (KYSA-8) is sufficient for filing—a massive regulatory win that de-risks the pathway for the entire autoimmune cell therapy sector.
While the FDA requested supplemental natural history data and 1-year follow-ups, Kyverna confirms no new trials are required. Clinical data is transformative: 67% of patients previously dependent on walkers could walk unaided after 16 weeks. Full submission is expected by Q4 2026.
This is the "Proof of Concept" moment for CAR-T moving beyond cancer into the multi-billion dollar autoimmune market. All eyes are now on $KYTX and its Chinese counterparts like $IASO and $BNDX racing for the same finish line.
