Material Changes and Clinical Results
The Company announced preliminary results from two trials for RAP-219, a therapy for focal epilepsy:
- PET Trial (RAP-219-103): Confirmed that the dosing regimen used in the ongoing Phase 2a trial (0.75 mg daily for 5 days, then 1.25 mg daily for 9 days) exceeded the target receptor occupancy (RO) range of 50%-70% within five days. The trial also confirmed that TARP g 8-containing AMPA receptors are enriched in the hippocampus and cerebral cortex.
- MAD-2 Trial (RAP-219-104): A double-blind, placebo-controlled trial in healthy volunteers. Results indicated RAP-219 was generally well tolerated with only Grade 1 or 2 adverse events. Notably, no sedation or motoric impairments were observed, differentiating it from many anti-seizure medications. Target exposures and RO were achieved within 5 days across various regimens.
- Executive Change: Bradley Galer, M.D., stepped down as Chief Medical Officer. A search for his successor is currently underway.
Outlook, Risks, and Management Commentary
Management highlighted that the clinical conduct of both the PET and MAD-2 trials is complete, with clinical study reports currently in progress. The data supports the continued development of RAP-219, demonstrating a differentiated tolerability profile and rapid achievement of therapeutic target engagement.
