ZUG, Switzerland, July 10, 2021 (GLOBE NEWSWIRE) – Pharvaris (Nasdaq: PHVS), a clinical-stage company focused on the development and commercialization of novel oral bradykinin B2 receptor antagonists for the treatment of angio- Hereditary edema (HAE) and other indications mediated by bradykinin-B2 receptors, today announced the presentation of clinical data supporting the multiple dose safety and pharmacokinetic (PK) profile of PHA121 (PHA-022121 ) for the treatment of hereditary angioedema (HAE) at the European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress 2021, to be held virtually July 10-16, 2021.
The double-blind, randomized, placebo-controlled, multiple-dose escalating study included 38 healthy male and female volunteers. PHA121 was administered orally after standardized twice-daily (BID) meals for 10 days in four sequential dose cohorts, ranging from 12 to 50 mg, with safety and pharmacokinetic evaluations during treatment and follow-up for 72 hours after the last dose. PHA121 was well tolerated up to the highest dose of 50 mg BID. All of the treatment-related adverse events (TREs) reported were mild and resolved completely. The total incidence and type of AEs were comparable between the active and placebo groups.
The data also show that PHA121 was well absorbed with median times to peak plasma concentrations within 1.00 to 1.75 hours after administration with standard meals. On day 1 and day 10, plasma exposure of PHA121 increased approximately dose-proportionally over the dose range of 12 to 50 mg with a mean half-life ranging from 4.8 to 7.3 hours after day. 10. At steady state, which was generally achieved within three days of treatment, plasma PHA121 levels remained consistently above the EC85 therapeutic threshold for all doses (as determined by human bradykinin challenge described above).
âThe pharmacokinetic profile demonstrated in this study suggests that the therapeutic effect of PHA121 can be achieved from the first day of administration, with steady state plasma levels achieved within three days. PHA121 was well tolerated in healthy volunteers up to 50 mg given twice daily for 10 days, âsaid Peng Lu, MD, Ph.D., chief medical officer of Pharvaris. âCombined with our bradykinin challenge data, which showed potent inhibition of bradykinin-induced hemodynamic effects, the pharmacokinetic and safety data observed in this study support future development to assess the efficacy and safety of prophylactic use of PHA121 in patients with HAE. “
Berndt Modig, CEO and co-founder of Pharvaris, added: âBradykinin-B2 receptor antagonism has been shown to be effective in the treatment of acute HAE attacks, but is currently not available as an oral treatment. . Pharvaris remains committed to providing patients with oral alternatives for both on-demand and prophylactic HAE therapy through our soft capsule formulation, PHVS416, and prolonged-release tablet formulation, PHVS719.

About PHVS416 PHVS416 is a capsule containing PHA121, a highly potent, specific and orally bioavailable competitive antagonist of the bradykinin B2 receptor. Pharvaris is developing this formulation to provide rapid exposure to an attack alleviating drug in a convenient small oral dosage form. PHVS416 is currently in phase 2 clinical development for the on-demand treatment of HAE.
About PHVS719 PHVS719 is an extended-release tablet formulation containing PHA121, a highly potent, specific and orally bioavailable competitive antagonist of the bradykinin B2 receptor. Pharvaris is developing this formulation to provide prolonged exposure to an attack prevention drug in a convenient small oral dosage form. PHVS719 is currently in preclinical development for the prophylactic treatment of HAE.
About PHA121 PHA121 (PHA-022121) is a highly potent, specific, and orally bioavailable competitive bradykinin B2 receptor antagonist that has completed Phase 1 clinical development for the treatment of HAE. PHA121 uses the same mechanism as icatibant, the main treatment for the on-demand treatment of HAE. Pharvaris is developing this new small molecule for the on-demand and prophylactic treatment of HAE and other bradykinin-mediated diseases through formulations optimized for each context.
