What this trial studies

This is a first-in-human, phase 1, placebo-controlled trial of ADX-626 in healthy adult volunteers. Participants will be assigned to receive ADX-626 or placebo and undergo regular blood sampling and clinical checks to measure safety, pharmacokinetics (PK), and pharmacodynamics (PD). Key entry requirements include age 18–45, weight ≥50 kg with BMI ≤25 kg/m2, normal laboratory tests, and females must be of non-childbearing potential. Study visits will include dosing, serial blood draws for PK/PD analysis, and safety monitoring for adverse events.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18–45 with body weight ≥50 kg and BMI ≤25 kg/m2, normal lab tests, no significant medical conditions, and who are male or women of non-childbearing potential willing to follow study procedures.

Not a fit: People with chronic medical conditions (for example hypertension, diabetes, cardiovascular disease, cancer), abnormal labs, current infection, recent participation in other interventional drug studies, women of childbearing potential, or those outside the 18–45 age range are unlikely to qualify or benefit from participation.

Why it matters

Potential benefit: If successful, this work could enable further development of ADX-626 and eventually lead to a new therapeutic option after later-phase testing.

How similar studies have performed: Many first-in-human phase 1 PK/PD trials successfully define safety and drug handling in healthy volunteers, but ADX-626 itself has not yet been tested in humans.
