AI Summary
Rapport Therapeutics announced that it will host its inaugural Investor and Analyst Day, where the executive team will share the company’s strategic priorities and offer updates on its clinical pipeline. A key focus of the event is the progress on the RAP-219 Phase 2a trial in focal epilepsy. This trial, which is now fully enrolled, is designed to assess the potential of RAP-219 in treating refractory focal epilepsy using intracranial EEG data as a measure of its effect on long episodes that correlate with clinical seizures. The event will also feature a fireside chat with Dr. Jacqueline French, a leading epilepsy expert from NYU Langone, who will discuss the trial design and the unmet needs in focal epilepsy. Materials and a live stream will be available on the company website, providing investors and analysts with in-depth insights into the company’s developments.

Announcement
Rapport Therapeutics, Inc. announced two encore poster presentations at the 2025 American Academy of Neurology (AAN) Annual Meeting, taking place from April 5 to April 9, 2025, in San Diego, California. The data from these posters was originally presented at the American Epilepsy Society (AES) Annual Meeting in December 2024.
AI Summary
Rapport Therapeutics, Inc. announced two encore poster presentations at the 2025 American Academy of Neurology (AAN) Annual Meeting in San Diego, California, scheduled for April 5–9, 2025. These presentations revisit data first shared at the American Epilepsy Society Annual Meeting in December 2024 and focus on the company's ongoing research and development of RAP-219, an AMPA receptor negative allosteric modulator now in Phase 2 trials for refractory focal epilepsy.
The first poster demonstrates that a 30% reduction in long episode frequency correlates with a clinically meaningful (≥50%) decrease in seizure activity. The second poster details how RAP-219 showed strong, dose-dependent antiseizure effects in preclinical models. These findings highlight the potential of RAP-219 as a precision treatment for epilepsy and underline Rapport Therapeutics’ commitment to advancing innovative therapies for neurological disorders.

Announcement
Rapport Therapeutics, Inc. announced results from its positron emission tomography (PET) trial and second multiple ascending dose (MAD-2) trial for RAP-219.
AI Summary
Rapport Therapeutics, Inc. announced promising results from two Phase 1 trials for RAP-219. In the positron emission tomography (PET) trial, RAP-219 reached and exceeded the target receptor occupancy needed for maximal efficacy within five days using the same dosing regimen as the current Phase 2a trial in focal epilepsy. The trial also confirmed that the targeted protein, TARP8, is mainly found in the hippocampus and cerebral cortex, with little expression in the cerebellum and brain stem. In the second multiple ascending dose (MAD-2) trial, RAP-219 was generally well tolerated even with faster dose titration and higher exposure levels compared to earlier studies. These results support the dosing strategy and highlight RAP-219’s broad therapeutic index, reinforcing its potential as a treatment in the ongoing clinical evaluation for focal epilepsy.

Announcement
Rapport Therapeutics, Inc Ongoing Phase 2a trial of RAP-219 in focal epilepsy is on track and topline data is expected in mid-2025
AI Summary
Rapport Therapeutics, Inc. announced promising updates from its trials for RAP-219, a treatment aimed at focal epilepsy. In the ongoing Phase 2a trial, RAP-219 is showing great promise with the current dosing regimen. Recent PET trial data confirmed that RAP-219 quickly reached and exceeded the target receptor occupancy needed for maximum efficacy within five days. This supports the approach used in the Phase 2a trial, and the drug was well tolerated by participants. The targeted action of RAP-219, focusing on TARP8 in key brain regions such as the hippocampus and cerebral cortex, suggests the potential for effective treatment with fewer side effects. Topline data from this trial is expected in mid-2025, marking an important milestone in developing a new option for patients struggling with refractory focal epilepsy.
