Data from randomized clinical studies and long-term extension studies support deucrictibant's potential best-in-class profile, detailing its injectable-like efficacy, placebo-like tolerability, and oral convenience
ZUG, Switzerland, Oct. 24, 2024 (GLOBE NEWSWIRE) -- Pharvaris (Nasdaq: PHVS), a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to prevent and treat hereditary angioedema (HAE) attacks, today announced data from seven posters that will be presented at the 2024 Annual Scientific Meeting of the American College of Allergy, Asthma & Immunology (ACAAI).
Pharvaris mourns our distinguished colleague, Prof. Marcus Maurer, who passed away during the development and finalization of these posters.
"The totality of data supporting deucrictibant's potential best-in-class profile in both prophylaxis and on-demand remains consistent and provides compelling validation for its continued clinical development,” said Peng Lu, M.D., Ph.D., Chief Medical Officer of Pharvaris. "The data presented at ACAAI continue to clinically derisk deucrictibant and contribute to excitement for deucrictibant to become a preferred therapy in HAE.”
The CHAPTER-1 Phase 2 data provide proof of the efficacy and safety of deucrictibant for the prevention of HAE attacks and support its further development as a potential prophylactic therapy for HAE, which will be presented by H. James Wedner, M.D. Specifically, Dr. Wedner explores deucrictibant's ability to decrease the median percentage of days with symptoms to 1.7% (40 mg/day) from 14.6% (placebo).
Results of the ongoing CHAPTER-1 open-label extension study provide further evidence on the long-term safety and efficacy of deucrictibant for prevention of HAE attacks and support further development of deucrictibant as a potential prophylactic therapy for HAE, which will be presented by John Anderson, M.D. Importantly, approximately 80% of participants achieved at least a 90% reduction in attack rate relative to the study baseline (as studied in the randomized clinical trial).
Pharvaris' confidence in the design of both the prophylactic and on-demand Phase 2 and Phase 3 studies is supported by nonclinical data in the bradykinin (BK) challenge model in non-human primates (NHPs). The pharmacokinetic and pharmacodynamic (PK/PD) profile of deucrictibant in the NHP BK challenge was shown to be predictive of the human PK/PD in the human BK challenge, as presented by Juan Bravo, Ph.D. Successful predictions of efficacious dosing of deucrictibant in humans were obtained following in-house modeling of nonclinical data, in line with the Phase 2 clinical studies of deucrictibant for both the prophylactic and the on-demand treatment of HAE attacks.

About Deucrictibant
Deucrictibant is a novel, potent, oral small-molecule bradykinin B2 receptor antagonist. By inhibiting bradykinin signaling through the bradykinin B2 receptor, deucrictibant has the potential to prevent the occurrence of HAE attacks and to treat the manifestations of an attack if/when they occur. Based on its chemical properties, Pharvaris is developing two formulations of deucrictibant for oral administration: an extended-release tablet to enable sustained absorption and efficacy in prophylactic treatment, and an immediate-release capsule to enable rapid onset of activity for on-demand treatment.
About Pharvaris
Pharvaris is a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to prevent and treat HAE attacks. By directly pursuing this clinically proven therapeutic target with novel small molecules, the Pharvaris team aspires to offer people with all types of HAE effective, well-tolerated, and easy-to-administer alternatives to treat attacks, both on-demand and prophylactically. With positive data in both Phase 2 prophylaxis and on-demand studies in HAE, Pharvaris is encouraged to further develop deucrictibant. Pharvaris is currently enrolling a pivotal Phase 3 study for the on-demand treatment of HAE attacks and plans to initiate a pivotal Phase 3 study of deucrictibant for the prevention of HAE by year-end 2024.
