ZUG, Switzerland, March 29, 2022 (GLOBE NEWSWIRE) -- Pharvaris (Nasdaq: PHVS), a clinical-stage company developing novel, oral bradykinin-B2-receptor antagonists to treat and prevent HAE attacks, building on its deep-seated roots in hereditary angioedema (HAE), today reported financial results for the fourth quarter and year ended December 31, 2021 and provided recent business highlights.

“The time since our initial public offering in February 2021 has been transformational for Pharvaris, enabling us to reach clinical development milestones, including initiation and continued progress of our Phase 2 RAPIDe-1 on-demand study of PHVS416, the initiation and enrollment of our Phase 2 CHAPTER-1 prophylactic study of PHVS416, and the completion of our Phase 1 pharmacokinetics study for PHVS719,” said Berndt Modig, chief executive officer of Pharvaris. “We look forward to our next milestones, including announcing top-line data from our Phase 2 trials, RAPIDe-1 and CHAPTER-1. We will continue to execute our strategy efficiently in 2022 supporting our mission to provide individual choice for managing HAE through potent and convenient oral on-demand and prophylactic therapies.”

Recent Business Highlights and Updates
Pipeline

• Top-line Phase 1 data demonstrate extended-release PHVS719 suitable for once-daily dosing. The Phase 1 pharmacokinetics (PK) study of PHVS719 included 8 healthy volunteers dosed in an open-label randomized five-period crossover single-dose study to assess bioavailability of two different extended-release formulations with and without food, in comparison to a single dose of PHVS416 without food. The pharmacokinetics of a single dose of PHVS719 (40 mg) under fasted conditions yielded exposure above 13.8 ng/mL (the EC₈₅ determined in a Phase 1 bradykinin challenge in healthy volunteers) by the two-hour timepoint and maintained this exposure for at least an additional 28 hours. The overall exposure was not affected by food. The 24-hour area-under-the-curve (AUC_24h) exposure of PHA121 using PHVS719 (40 mg) is similar to that observed in Phase 1 studies with PHVS416 softgel capsules dosed 20 mg twice a day with food (one of the doses used in the CHAPTER-1 prophylactic proof-of-concept study). The study showed that PHVS416 and PHVS719 were well tolerated. During the study, there were no severe adverse events (SAEs) or severe treatment-emergent adverse events (TEAEs) reported.
  
  “We are thrilled to have achieved with the PHVS719 extended-release formulation for the first time the possibility of a once-daily oral bradykinin receptor antagonist for prevention of hereditary angioedema attacks,” said Jochen Knolle, CSO of Pharvaris. “The versatile properties of PHA121, in this case the ability to be absorbed through the colon, combined with the appropriate slow-release technologies, has enabled a release profile well-suited to all-day exposure of compound. This single-dose study showed that PHVS719 (40 mg) maintained PHA121 exposure for a full day above the levels that prevented the effects of a surge of bradykinin as shown in our mechanistic study in healthy volunteers. We look forward to confirming these results in an upcoming multi-dose PK study, to support use of PHVS719 in a future pivotal clinical study when combined with the anticipated results of our CHAPTER-1 proof-of-concept study.”
  

• Orphan Drug Designation granted by FDA. On March 18, 2022, the FDA granted orphan drug designation to PHA121, the active ingredient in our PHVS416 and PHVS719 product candidates, for treatment of bradykinin-mediated angioedema.
  
  
• Phase 2 on-demand study (RAPIDe-1) of PHVS416 ongoing. RAPIDe-1, a Phase 2 clinical study of PHVS416 for the on-demand treatment of HAE attacks, continues enrollment and attack surveillance across 33 clinical sites in Canada, Europe, Israel, the UK and the U.S. Top-line data from the study is anticipated to be available in the fourth quarter of 2022.
  
  
• Phase 2 prophylactic study (HAE CHAPTER-1) of PHVS416 enrollment ongoing. CHAPTER-1, a Phase 2 clinical trial of PHVS416 for the prophylactic treatment of HAE attacks, is enrolling patients across clinical sites in Canada, Europe, Israel, the UK and the U.S. Top-line data from the study is anticipated to be available in the fourth quarter of 2022.
  
  
• RAPIDe-2 expected to initiate in 2022. RAPIDe-2, an open-label extension study evaluating PHVS416 for the on-demand treatment of people with HAE, is expected to initiate in the second half of 2022.
  
  
• Preclinical data of PHA121 published in International Immunopharmacology. In March 2022, Pharvaris announced the publication of preclinical data in International Immunopharmacology demonstrating the specificity and potency of PHA121, the active ingredient in our PHVS416 and PHVS719 product candidates.

About RAPIDe-1
The RAPIDe-1 study is a clinical research study for people who have been diagnosed with HAE. The main purpose of the study is to find out how effective three different doses of the study drug, PHVS416, are in relieving symptoms associated with HAE attacks. Researchers developed the study drug in the form of softgel capsules which are taken orally and could be a more convenient alternative to an injection into a vein or under the skin for resolving HAE attacks. For more information, visit https://hae-rapide.com/, https://hae-rapide.us/, or https://clinicaltrials.gov/ct2/show/NCT04618211.

About HAE CHAPTER-1
The HAE CHAPTER-1 study is a clinical research study for people who have been diagnosed with HAE. The main purpose of the study is to evaluate two different doses of the study drug, PHVS416, in preventing HAE attacks. Researchers developed the study drug in the form of softgel capsules which are taken orally and could be a more convenient alternative to an injection into a vein or under the skin for preventing HAE attacks. For more information, visit https://haechapter-1.com or https://clinicaltrials.gov/show/NCT05047185.

About PHVS416
PHVS416 is a softgel capsule formulation containing PHA121, a highly potent, specific, and orally bioavailable competitive antagonist of the bradykinin B2 receptor. Pharvaris is developing this formulation to provide fast and reliable symptom relief when patients want, through rapid exposure of attack-mitigating medicine 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 an easy way to prevent attacks with sustained exposure of attack-preventing medicine in a convenient, small oral dosage form. PHVS719 is currently in Phase 1 clinical development for the prophylactic treatment of HAE.

About PHA121
PHA121 (PHA-022121) is a highly potent, specific, and orally bioavailable competitive antagonist of the bradykinin B2 receptor that has completed Phase 1 clinical development for the treatment of HAE. PHA121 utilizes the same mechanism as icatibant, the leading therapy for on-demand treatment of HAE. Pharvaris is developing this novel small molecule for on-demand and prophylactic treatment of HAE and other bradykinin-mediated diseases through formulations optimized for each setting. Data from single- and multiple-ascending-dose Phase 1 studies in healthy volunteers demonstrate rapid exposure and linear pharmacokinetics at doses up to 50 mg. In a bradykinin-challenge study in healthy volunteers, PHA121 showed significant inhibition of bradykinin-induced hemodynamic changes with an average composite EC₅₀ of 2.4 ng/mL and EC₈₅ of 13.8 ng/mL, approximately four-fold more potent than historical data for icatibant. Quantitative modeling indicates that single oral doses of PHA121 will maintain pharmacological effectiveness for a substantially longer time than 30 mg of subcutaneous icatibant. PHA121 has been observed to be well-tolerated at all doses studied to date.
