## Exhibit 99.1

#### Exhibit 99.1

### Pharvaris Provides Regulatory, Clinical, and Corporate Updates
**ZUG, Switzerland, January 9, 2023 – <u>Pharvaris</u> (Nasdaq: PHVS), a clinical-stage company developing novel, oral bradykinin-B2-receptor antagonists to treat and prevent hereditary angioedema (HAE) attacks, today provided business updates and company highlights.** 

#### Business Updates and Company Highlights
• **Meeting minutes from Type A meeting with U.S. Food and Drug Administration (FDA) received.** Pharvaris will conduct a 26-week rodent toxicology study to resolve the clinical holds in the U.S. The protocol for this nonclinical study has been submitted to the FDA for review.

• **FDA approval of dosing of final U.S. participants in RAPIDe-1 received.** The FDA has agreed to partially lift the hold on on-demand to allow the two remaining U.S. participants in RAPIDe-1 to complete treatment of the last attack per the protocol. Positive top-line data from RAPIDe-1 was <u>announced</u> in December 2022. RAPIDe-2, a long-term extension study of PHVS416 for the on-demand treatment of HAE, is currently on hold in the U.S. and is underway outside the U.S.

• **Top-line data from CHAPTER-1, a global Phase 2 study of PHVS416 for the prophylactic treatment of HAE attacks, anticipated 2H2023.** CHAPTER-1 is currently on hold in the U.S. All active sites outside of the U.S. continue to recruit participants in the CHAPTER-1 clinical study. After being notified of the clinical holds in the U.S. by the FDA, Pharvaris informed country-specific regulatory authorities in Canada, Europe, Israel, and the UK regarding the clinical holds in the U.S. To date, the regulatory status of the CHAPTER-1 study outside the U.S. remains unchanged. Based on the Company's current assumptions regarding ex-U.S. regulatory status and enrollment, Pharvaris anticipates announcing top-line data from the CHAPTER-1 trial in 2H2023.

• **Cash runway into 4Q2024.** Pharvaris remains diligent in its operational management and is focusing on its existing clinical HAE pipeline to extend runway into 4Q2024.

#### Upcoming Data Presentation
• **American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting.** San Antonio, TX, February 24-27, 2023. Details for the accepted poster presentation at AAAAI are as follows:

o **Title:** Efficacy And Safety Of Bradykinin B2 Receptor Inhibition With Oral PHVS416 In Treating Hereditary Angioedema Attacks: Results Of RAPIDe-1 Phase 2 Trial

o **Presenter:** Prof. Marcus Maurer

o **Date, Time:** Sunday, February 26, 2023, 9:45-10:45 a.m. CST

MSCS and TOS: definitions 44 Validated patient-reported outcome measures to comprehensively capture symptom severity and change of HAE attacks MSCS (Mean Symptom Complex Severity) score is a point-in-time measure of symptom severity: Patients rated the severity of each affected symptom on a categorical scale (0 = normal, 1 = mild, 2 = moderate, 3 = severe) Calculated as average score from all affected anatomic sites of attack (symptom complexes or SC) pre-treatment Decrease in MSCS score reflects improvement in symptom severity TOS (Treatment Outcome Score) is a measure of symptom response to treatment: Patient assessment of response for each affected SC recorded on categorical scale (significant improvement [100], improvement [50], same [0], worsening [-50], significant worsening [-100]) Calculated as weighted average of the response at all SC using pre-treatment severity as the weight TOS value >0 reflects improvement in symptoms from pre-treatment
