Investor Verification Checklist
- Verify the specific timing and criteria for the first Phase 2 patient dosing of KT-474 to confirm milestone payment eligibility.
- Review the full text of the Amended Sanofi Agreement (expected in the 2022 Form 10-K) for detailed termination clauses and royalty adjustment mechanisms.
- Monitor upcoming 2023 data releases for KT-333 and KT-413 to assess dose escalation safety and efficacy trends.
