PRA-216 for healthy adults and adults with mild-to-moderate asthma

A Phase 1 Randomized, Double-Blind, Placebo-Controlled, Single Ascending and Multiple Ascending Dose Study Investigating PRA-216 in Healthy Volunteers Followed by a Phase 2a Randomized, Double-Blind, Placebo-Controlled Study in Participants With Mild-to-Moderate Asthma

Phase1; Phase2 Interventional Prana Therapies Inc · NCT07245368

This trial will test whether PRA-216 is safe, how it behaves in the body, and whether it shows benefit in adults with mild-to-moderate asthma compared with placebo.

What this trial studies

This Phase 1/2a study first gives single and then repeated ascending doses of PRA-216 to healthy adults to measure safety, tolerability, pharmacokinetics, and immunogenicity, using both intravenous and subcutaneous routes in Phase 1. Phase 2a is a randomized, double-blind, placebo-controlled portion that gives the selected Phase 1 dose to adults with mild-to-moderate asthma to collect additional safety, immunogenicity, pharmacokinetic, and preliminary efficacy data. Dose escalations are staggered and controlled, with close monitoring for adverse events and antibody responses. The trial uses placebo control and blinding in Phase 2a to compare outcomes robustly while early parts focus on determining a safe dose and schedule.

Who should consider this trial

Good fit: Ideal candidates are adults 18 to 65 with mild-to-moderate asthma (for Phase 2a) who are able and willing to attend study visits and meet the study's health and consent requirements.

Not a fit: Patients with severe asthma, significant medical comorbidities, recent blood donation, recent nicotine use, a history of severe allergic reactions, or those outside the 18–65 age range are unlikely to qualify or benefit from this protocol.

Why it matters

Potential benefit: If successful, PRA-216 could become a new treatment option that improves asthma control with a defined safety and dosing profile.

How similar studies have performed: Other biologic and immunomodulatory approaches have shown benefit in specific asthma subtypes, but PRA-216 itself is investigational and has not yet been proven effective in patients.
