Data Supporting The Potentially Differentiated Pharvaris Portfolio Presented At ACAAI 2025 Annual Scientific Meeting
- Open-label prophylaxis data supporting the long-term safety profile and sustained benefits of deucrictibant, as well as clinical validation data of a kinin biomarker assay were highlighted in two oral presentations Final data from participants in the open-label portion of the CHAPTER-1 study provide further evidence of a well-tolerated safety profile for up to approximately 34 months and an average of 92.4% attack reduction from study baseline with deucrictibant treatment Six additional posters detail the effectiveness, safety, and health-related quality of life outcomes from various clinical studies with additional evidence on deucrictibant's potentially differentiated profile in HAE
ZUG, Switzerland, Nov. 10, 2025 (GLOBE NEWSWIRE) -- Pharvaris (Nasdaq: PHVS), a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to help address unmet needs of those living with bradykinin-mediated diseases such as hereditary angioedema (HAE) and acquired angioedema due to C1 inhibitor deficiency (AAE-C1INH), summarized the presentations from the 2025 Annual Meeting of the American College of Allergy, Asthma, and Immunology (ACAAI), including data from two oral presentations and six posters, which took place from November 6-10, 2025, in Orlando, Fla.
“We are proud about the recognition of the scientific community of the importance attributed to the late-stage confirmatory clinical data of deucrictibant and the associated biomarker work as oral presentations at the American College for Allergy, Asthma and Immunology annual conference. Beyond the scientific merit we are looking forward to the potential impact deucrictibant could have on the lives of people living with bradykinin-mediated angioedema,” said Berndt Modig, Chief Executive Officer of Pharvaris.

Long-Term Safety and Efficacy of Oral Deucrictibant for Prophylaxis in Hereditary Angioedema: CHAPTER-1 Open-Label Extension
Peng Lu, M.D., Ph.D., Chief Medical Officer of Pharvaris, stated“We are encouraged by the continued positive outcomes in the long-term prophylactic setting that deucrictibant has demonstrated in its clinical studies to date. We appreciate the importance of providing placebo-controlled efficacy and safety data for deucrictibant and therefore look forward to the anticipated Phase 3 data readout of CHAPTER-3 in the second half of 2026. The totality of data, including the placebo-controlled efficacy and safety data from Part 1 of the CHAPTER-1 study, the open-label safety, effectiveness, and health-related quality of life data from Part 2 of the CHAPTER-1 study, and our healthy volunteer and nonclinical PK/PD and safety data, create a compelling data package for deucrictibant in the competitive prophylactic bradykinin-mediated angioedema space, which we hope to confirm with pivotal Phase 3 data.”

Dr. Lu continued,“Current unmet needs for on-demand HAE treatments support further investigation into a therapy that could potentially provide a rapid and durable response to treatment through complete resolution with a single capsule, and also address the physical, functional, and emotional burden associated with HAE attack manifestations. RAPIDe-3 data readout, which is expected in the fourth quarter of this year, will provide additional evidence on deucrictibant's ability to address these unmet needs.”

Anne Lesage, Ph.D., Chief Early Development Officer of Pharvaris, stated,“Through the reliable and reproducible measurement of levels of bradykinin and its breakdown peptides in plasma, we can assess bradykinin-forming cascade sensitivity, thereby potentially identifying further applications for deucrictibant as a bradykinin B2 receptor antagonist.”

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, Swissmedic, and the European Commission.
About Pharvaris
Pharvaris is a late-stage biopharmaceutical company developing novel, oral bradykinin B2 receptor antagonists to potentially address all types of bradykinin-mediated angioedema. Pharvaris intends to provide injectable-like efficacyTM and placebo-like tolerability with the convenience of oral therapies to prevent and treat bradykinin-mediated angioedema attacks. With positive data in both Phase 2 prophylaxis and on-demand studies in HAE, Pharvaris is currently evaluating the efficacy and safety of deucrictibant in a pivotal Phase 3 study for the prevention of HAE attacks (CHAPTER-3) and a pivotal Phase 3 study for the on-demand treatment of HAE attacks (RAPIDe-3).
