Rapport Therapeutics to Present Data at the 2025 American Academy of Neurology Annual Meeting

BOSTON and SAN DIEGO, March 21, 2025 (GLOBE NEWSWIRE) -- Rapport Therapeutics, Inc. (Nasdaq: RAPP) (“Rapport” or the “Company”), a clinical-stage biotechnology company dedicated to the discovery and development of small molecule precision medicines for patients with neurological or psychiatric disorders, today 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. The presentations will highlight the company’s ongoing research and development of RAP-219, a clinical-stage AMPA receptor (AMPAR) negative allosteric modulator (NAM) currently in Phase 2 development for the treatment of refractory focal epilepsy. Rapport will showcase the following posters: Poster #002: Optimal Cut Point for Reduction in Long Episode Frequency to Predict Meaningful Change in Clinical Seizure Frequency (Monday, April 7, 2025 from 8:00 AM to 9:00 AM PT) –Using a receiver operator characteristic (ROC) analysis, the data confirmed that a 30% reduction in LE frequency was the optimal cut point associated with a clinically meaningful (≥50%) reduction in clinical seizures, regardless of the antiseizure medication initiated, revealing a linear relationship between long episode and clinical seizure frequencies.Poster #003: Antiseizure Effects with Selective TARPγ8 Negative Allosteric Modulators in Preclinical Seizure Models (Tuesday, April 8, 2025 from 11:45 AM to 12:45 PM PT) - RAP-219 provided potent, dose-dependent antiseizure effects in pentylenetretrazol (PTZ) and corneal kindling preclinical seizure models, with maximal protection observed with 70% receptor occupancy and RAP-219 mean plasma concentration of 7 ng/mL.

About RAP-219RAP-219 is a clinical-stage AMPA receptor (AMPAR) negative allosteric modulator (NAM) designed to achieve neuroanatomical specificity through its selective targeting of a receptor associated protein (RAP) known as TARPγ8, which is associated with neuronal AMPARs. Whereas AMPARs are distributed widely in the central nervous system, TARPγ8 is expressed only in discrete regions, including the hippocampus and neocortex, where focal seizures often originate. By contrast, TARPγ8 has minimal expression in the hindbrain, where drug effects are often associated with intolerable adverse events. With this precision approach, the Company believes RAP-219 has the potential to provide a differentiated profile as compared to traditional neuroscience medications. Due to the role of AMPA biology in various neurological disorders and the selective targeting of TARPγ8, the Company believes RAP-219 has pipeline-in-a-product potential and is evaluating the compound as a transformational treatment for patients with focal epilepsy, bipolar disorder, and peripheral neuropathic pain. About Rapport TherapeuticsRapport Therapeutics is a clinical-stage biotechnology company dedicated to discovering and developing small molecule precision medicines for patients with neurological or psychiatric disorders. The Company’s founders have made pioneering discoveries related to the function of receptor associated proteins (RAPs) in the brain. Their findings form the basis of Rapport’s RAP technology platform, which enables a differentiated approach to generate precision small molecule product candidates with the potential to overcome many limitations of conventional neurology drug discovery. Rapport’s precision neuroscience pipeline includes the Company’s lead investigational drug, RAP-219, designed to achieve neuroanatomical specificity through its selective targeting of a RAP expressed in only discrete regions of the brain. The Company is currently pursuing RAP-219 as a potential treatment for refractory focal epilepsy, bipolar mania and diabetic peripheral neuropathic pain. Additional preclinical and late-stage discovery stage programs are also underway, including targeting chronic pain and hearing disorders. Forward-Looking StatementsThis press release contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, each as amended. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. These forward-looking statements include, but are not limited to, express or implied statements regarding: the expected impact of reductions in long episode frequency as measured by the RNS® System, including but not limited to Rapport’s ability to predict clinically meaningful seizure reduction; the clinical development of RAP-219 for the treatment of drug-resistant focal epilepsy, bipolar mania and diabetic peripheral neuropathic pain; the potential activity and tolerability of RAP-219; and the potential of Rapport’s RAP technology platform. Forward looking statements are based on management’s current expectations and are subject to risks and uncertainties that could negatively affect Rapport’s business, operating results, financial condition and stock value. Factors that could cause actual results to differ materially from those currently anticipated include: risks relating to the company’s research and development activities; Rapport’s ability to execute on its strategy including obtaining the requisite regulatory approvals on the expected timeline, if at all; uncertainties relating to preclinical and clinical development activities; the company’s dependence on third parties to conduct clinical trials, manufacture its product candidates and develop and commercialize its product candidates, if approved; Rapport’s ability to attract, integrate and retain key personnel; risks related to the company’s financial condition and need for substantial additional funds in order to complete development activities and commercialize a product candidate, if approved; risks related to regulatory developments and approval processes of the U.S. Food and Drug Administration and comparable foreign regulatory authorities; risks related to establishing and maintaining Rapport’s intellectual property protections; and risks related to the competitive landscape for Rapport’s product candidates; as well as other risks described in “Risk Factors,” in the company’s Registration Statement on Form S-1, and most recent Quarterly Report on Form 10-Q, as well as discussions of potential risks, uncertainties, and other important factors in Rapport’s subsequent filings with the Securities and Exchange Commission. Rapport expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in its expectations or any changes in events, conditions or circumstances on which any such statement is based, except as required by law, and claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.
