Is this trial a fit for you?

Likely a good fit

Healthy adults aged 18–55 with a BMI of 18–32 kg/m2, body weight ≥50 kg, and no clinically significant medical problems are ideal candidates.

Probably not a fit

People who are pregnant or breastfeeding, outside the age or BMI limits, have positive HIV/hepatitis tests, or have active medical conditions will not be eligible and are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1, randomized, double-blind, placebo-controlled study uses single-ascending-dose (SAD) and multiple-ascending-dose (MAD) cohorts to characterize safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of HX15001. Part A includes seven sequential SAD cohorts with subcutaneous dosing for Cohorts 1–5 and intravenous infusions for Cohorts 6–7. Part B includes two MAD cohorts with subcutaneous doses on Days 1, 15, and 43. Cohort sizes range from four to eight participants, and follow-up extends up to about 20 weeks to monitor safety and drug exposure.

Why it matters

Potential benefit: If HX15001 is safe, the results could identify appropriate dosing and support future patient studies.

How similar studies have gone: The SAD/MAD randomized, placebo-controlled design is a standard first-in-human approach, but HX15001 itself has not yet reported human results.
