First‑in‑human test of ARD001 in healthy adults and people with hemophilia A
Official title: A Phase 1 Randomized, Double-Blind, Placebo-Controlled, Single-Ascending-Dose Study Investigating the Safety and Tolerability of ARD001 in Healthy Adult Subjects and a Phase 2 Open-Label, Multiple-Dose Study in Adult Subjects With Hemophilia A
Run by Arditus Pte Ltd · NCT07787091 · Data updated 2026-11-12
This study tests ARD001 to see if it is safe and tolerable in healthy adults and in people with hemophilia A, using a single dose (Phase 1) and potentially repeated doses (Phase 2) if results look good.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include healthy adults across specified age and weight ranges and adults with hemophilia A who meet the protocol’s criteria for Phase 2 evaluation.
✕Probably not a fit
Some participants, particularly those with certain health conditions or intolerances, may not experience any direct benefit and could face risks without therapeutic gain.

What this trial studies
This is a first‑in‑human interventional study testing ARD001. Phase 1 enrolls healthy adult participants who will receive a single dose of ARD001 or placebo to assess safety, pharmacokinetics, coagulation effects, and antibody development. Depending on safety and regulatory approvals, Phase 2 would evaluate multiple dosing in adults with hemophilia A to identify dose regimens for future trials. The trial aims to determine whether ARD001 can be administered safely and at doses suitable for further development. Primary results will inform next steps in development for people with hemophilia A.
Why it matters
Potential benefit: If successful, ARD001 could become a safe treatment option that helps manage bleeding in hemophilia A.
How similar studies have gone: Early human studies of similar approaches have shown safety signals that support continuing development, though this specific ARD001 program is early and not yet proven.
