What this trial studies

This Phase 1 ethnobridging trial tests pharmacokinetics, pharmacodynamics, and safety of AGA2118 after a single dose in healthy Japanese, Chinese, and Caucasian adults. Eighteen Japanese participants are randomized 1:1:1 to three dose levels and followed for 85 days after dosing. After the Japanese cohorts, six Caucasian participants and six Chinese participants will each receive the highest dose, with Caucasians matched to the Japanese group by sex and weight. The study collects blood samples and safety assessments to compare how the drug is processed and tolerated across the three ethnic groups.

Who should consider this trial

Good fit: Healthy adults aged 18 to 65 who meet the study's Japanese, Chinese, or Caucasian ethnicity criteria, have adequate vitamin D levels, and have no recent major medical events are eligible.

Not a fit: People who are pregnant or breastfeeding, have recent fractures, recent myocardial infarction or stroke, recent malignancy, abnormal calcium levels, or who do not meet the ethnicity criteria are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, results could define appropriate dosing and safety information for AGA2118 across Japanese, Chinese, and Caucasian populations to inform future patient trials.

How similar studies have performed: Ethnobridging single-dose PK/safety studies are a common, established approach and similar early-phase trials have successfully guided dosing across ethnic groups.
