Pharvaris announced clinical data from its Phase 1 multiple-ascending-dose study demonstrating PHA121's pharmacokinetics and tolerability. PHA121 was well tolerated at all doses studied, with approximately dose-proportional exposure. The Phase 1 randomized, double-blind, placebo-controlled, multiple ascending dose trial examined the safety, tolerability, and pharmacokinetics of PHA121 in healthy volunteers. The trial included 38 healthy subjects dosed twice daily (BID) for 10 days in four sequential dosing cohorts, ranging from 12 to 50 mg. During the study, PHA121 was well tolerated up to the dose of 50 mg BID. All reported treatment-emergent adverse events (TEAEs) were mild in intensity and resolved completely. The total incidence and type of TEAEs were similar between active drug and placebo groups. Lab safety, vital signs, and ECG parameters remained well within normal limits in all subjects. The pharmacokinetic profile suggests that therapeutic drug levels of PHA121 were achieved in day 1 and steady-state plasma concentrations were reached within 72 hours.
