Is this trial a fit for you?

Likely a good fit

Healthy adults aged 18–65 without significant medical conditions who consent to participate and comply with study procedures.

Probably not a fit

Healthy volunteers without autoimmune disease may not gain direct therapeutic benefit from PF-08065010.

What this trial studies

This early-phase study investigates the safety, tolerability, and pharmacology of PF-08065010 across two parts. Part A involves a single dose with in-clinic monitoring over about five months, including multiple visits. Part B assesses repeated monthly dosing for three months, with ongoing follow-up. Participants receive either PF-08065010 or placebo by injection or IV infusion at a Pfizer clinic in Brussels, under strict eligibility and safety monitoring.

Why it matters

Potential benefit: If safe and well-tolerated, findings could guide dosing for future studies in autoimmune conditions.

How similar studies have gone: Fewer data exist for PF-08065010 in healthy volunteers, making this a novel early-phase evaluation of safety and pharmacology.
