Fewer attacks treated with second dose or rescue medication within 12 hours: 83.0% of attacks were treated with a single capsule of deucrictibant IR

93.2% of deucrictibant-treated attacks were treated without use of rescue medication

Marc A. Riedl, M.D., M.S., Professor of Medicine, Clinical Director of the U.S. Hereditary Angioedema Association (HAEA) Angioedema Center at the University of California San Diego (UCSD), and principal investigator in the RAPIDe-3 study, commented, “Bradykinin B2 receptor antagonism is a proven and effective mechanism for treatment of bradykinin-mediated angioedema. Injectable and oral on-demand therapies for HAE are available, however unmet medical needs remain. Effective, well-tolerated, and convenient acute treatment is an essential part of all HAE management plans due to unpredictable angioedema symptoms. The comprehensive and compelling outcomes of RAPIDe-3, specifically the fast treatment response and early complete symptom resolution, demonstrate the potential benefits of deucrictibant as an important on-demand treatment for people living with HAE.”

Peng Lu, M.D., Ph.D., Chief Medical Officer of Pharvaris, stated, “I would like to sincerely thank the clinical study participants and their caregivers, the site investigators and staff, our study partners, the HAE community, and the Pharvaris team for their contributions to the RAPIDe-3 study. Together, we carefully designed and rigorously executed a study evaluating deucrictibant’s ability to effectively address the unmet needs and high expectations of physicians, regulators, payers, and, most importantly, people living with HAE.”

Dr. Lu continued, “These clinically meaningful and statistically significant results demonstrate deucrictibant’s early-onset treatment response, fast symptom relief and resolution, and well-tolerated safety profile. This is an important step toward realizing deucrictibant’s potential to offer control of bradykinin-mediated angioedema attacks. With these data in hand, our team is working diligently to prepare for regulatory filings to enable access to this promising therapy.”

Berndt Modig, Chief Executive Officer of Pharvaris, added, “Since its founding, Pharvaris has spent the last decade pioneering science for patient choice. Deucrictibant combines the proven and effective mechanism of bradykinin B2 receptor antagonism in HAE with the convenience of oral administration. We are thrilled that RAPIDe-3 confirmed the profile of deucrictibant IR capsule established in Phase 2. If the CHAPTER-3 pivotal Phase 3 study confirms deucrictibant extended-release tablet as a long-term prophylactic of HAE attacks, deucrictibant could be the first and only oral therapy to offer control in both the on-demand and prophylactic treatment of bradykinin-mediated angioedema attacks.”

In RAPIDe-3, deucrictibant was well tolerated with no treatment-related serious adverse events and no participants discontinuing treatment due to treatment-emergent adverse events. To date, the safety and tolerability profile was consistent with completed and ongoing studies of deucrictibant for the treatment of HAE attacks with no safety signals identified.

An open-label extension of deucrictibant for the on-demand treatment of HAE attacks, RAPIDe-2 Part B, is ongoing.

Pharvaris plans to present additional efficacy, safety, and patient experience data at upcoming medical congresses.

Pharvaris remains on track to submit a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in the first half of 2026 for the on-demand treatment of acute attacks of HAE.

Conference Call Pharvaris will host a live conference call and webcast to discuss the RAPIDe-3 study topline data in greater detail at 8:00 a.m. EST today via a live webcast ; presentation slides may be accessed on the “ Events and Presentations ” page of the Pharvaris investor relations website. Participants interested in asking a verbal question during the Q&A may do so in the live conference call . An archived replay will also be available on the website for 90 days following the event.

About Deucrictibant Deucrictibant is a novel, potent, orally bioavailable small-molecule bradykinin B2 receptor antagonist currently in clinical development. Deucrictibant is being investigated for its potential to prevent the occurrence of bradykinin-mediated angioedema attacks and to treat the manifestations of attacks if/when they occur by inhibiting bradykinin signaling through the bradykinin B2 receptor. Pharvaris is developing two formulations of deucrictibant for oral administration: an extended-release tablet to enable sustained absorption and efficacy as prophylactic treatment, and an immediate-release capsule to enable rapid onset of activity for on-demand treatment. Deucrictibant has been granted orphan drug designation for the treatment of bradykinin-mediated angioedema by the U.S. Food and Drug Administration, the European Commission, and Swissmedic.

About Pharvaris Pharvaris is a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to help address unmet needs in bradykinin-mediated conditions, including all types of bradykinin-mediated angioedema. Pharvaris’ aspiration is to offer therapies with injectable-like efficacy™, a well-tolerated profile, and the convenience of oral administration to prevent and treat bradykinin-mediated angioedema attacks. By delivering on this aspiration, Pharvaris aims to provide a new standard of care in bradykinin-mediated angioedema. Pharvaris is preparing global marketing authorization applications for deucrictibant immediate-release capsule as an on-demand treatment of HAE attacks, and a global pivotal Phase 3 study of deucrictibant extended-release tablet for the prevention of HAE attacks (CHAPTER-3) is ongoing with topline data anticipated in the second half of 2026. In addition, CREAATE is an ongoing Phase 3 study of deucrictibant for the prophylactic and on-demand treatment of AAE-C1INH. For more information, visit https://pharvaris.com/ .
