Material Changes and Clinical Updates
- PROACT 1 Study Enrollment: The Company is on track to complete enrollment for the Phase 3 PROACT 1 accelerated approval analysis in mid-2026.
- Statistical Powering Update: The statistical powering assumption for the surrogate endpoint (eGFR slope) analysis in the PROACT 1 study has been updated to 80%. The confirmatory endpoint analysis remains at 80% power.
- Study Design Context: The study is designed with 90% power to detect an effect size in annualized eGFR slope of 1.75 mL/min/1.73m² and 80% power to detect an effect size of 1.5 mL/min/1.73m². The FDA has agreed that an effect size of 1.5 mL/min/1.73m² is acceptable for efficacy demonstration under the RMAT designation.
- Historical Context: In the Phase 2 REGEN-007 study (Group 1), bilateral kidney injections were associated with a 4.6 mL/min/1.73m² improvement in the annual decline in eGFR slope.
Guidance, Outlook, and Risks
Outlook and Milestones
- Topline Results: Pivotal topline results for the PROACT 1 study are anticipated in Q2 2027.
