REM-001: CMBC Development Plan
Development plan optimized for success while minimizing cost
• Phase 3 ready
• Initial open-label, 15-patient study to confirm lower dose and optimize trial design
• Leverages prior data indicating lower dose can improve outcome
- Faster healing
- Less photosensitivity
• De-risks full Phase 3 study
IND reactivated August 2022
Fast Track designation received from the FDA in November 2022
National Institutes of Health Grant awarded June 2023
