NCT06683040

Brief Summary

A multicenter, randomized, double-blind, placebo-controlled, phase II-III clinical trial to evaluate the efficacy and safety of the study drug in adult patients with pulmonary arterial hypertension (PAH). The trial will evaluate the efficacy and safety of both single and multi-dose (seven-day) administrations of the study drug in three dosages: 0.03 mg/kg, 0.10 mg/kg, and 0.17 mg/kg. The trial is an observer-blinded trial, since the appearance of the study drug and Placebo differs from each other. Patients included in the trial, as well as trial coordinators, investigators, and study center staff will be blinded. The only unblinded staff in the study centers will be those who preparing IP/Placebo and administering IP/Placebo to the study patients. The trial will include 200 patients with PAH, who will be sequentially included in the trial in two stages.

Outcome Measures

Primary Outcomes (1)

  • Pulmonary vascular resistance (PVR) will be measured to assess and evaluate the efficacy of study drug in comparison with placebo in patients with pulmonary arterial hypertension (PAH).

    To evaluate the efficacy of single doses of the investigational product compared with placebo in patients with pulmonary arterial hypertension (PAH), we will measure pulmonary vascular resistance (PVR)

    6 hours after the start of the IP administration
