• Positive Phase 2a Data for RAP-219 in FOS

  Follow-up data from the Phase 2a trial of RAP-219 in focal onset seizures (FOS) demonstrated sustained seizure reduction, including a 90% median reduction in clinical seizures over baseline in weeks 9-12. The estimated half-life of RAP-219 was also extended to 22 days from 14 days.

• Bipolar Mania Phase 2 Results Accelerated

  Topline results for the Phase 2 trial of RAP-219 in bipolar mania are now expected in the fourth quarter of 2026, ahead of the previous guidance of the first half of 2027. The trial's statistical analysis plan was also modified to potentially serve as confirmatory evidence of effectiveness.

• Extended Cash Runway into H2 2029

  The company ended Q1 2026 with $476.8 million in cash, cash equivalents, and short-term investments, which is expected to fund operations into the second half of 2029.

• Strategic Collaboration with Tenacia Biotechnology

  Rapport entered into a collaboration and license agreement with Tenacia Biotechnology for the development and commercialization of RAP-219 in Greater China, generating $20.0 million in collaboration revenue for Q1 2026.

This 8-K filing details a highly positive first quarter for Rapport Therapeutics, marked by significant clinical advancements, a new revenue stream, and a substantially extended financial runway. The positive Phase 2a follow-up data for RAP-219 in focal onset seizures, demonstrating a 90% median seizure reduction, reinforces the potential of their lead candidate. Critically, the acceleration of topline results for the bipolar mania Phase 2 trial, coupled with its modification for potential confirmatory evidence, signals strong progress and confidence in a key pipeline program. The strategic collaboration with Tenacia Biotechnology provides new collaboration revenue, and the projected cash runway into the second half of 2029 significantly de-risks the company's operations and future development plans. These combined factors present a compelling positive outlook for investors.
