NCT07780604

Brief Summary

This first-in-human Phase 1 study evaluated the safety, tolerability, and pharmacokinetics of GAL-101 salt following oral administration to healthy adult and elderly participants. A total of 92 participants were enrolled at a single study center. The study consisted of five parts. Part 1 evaluated single ascending doses of enteric-coated GAL-101 capsules compared with placebo in healthy adults. Part 2 compared a single dose of enteric-coated GAL-101 capsules with uncoated GAL-101 salt mixed with apple sauce in an open-label crossover design. Part 3 evaluated the effect of fasting, a standard meal, and a high-fat, high-calorie meal on the pharmacokinetics of a single dose of uncoated GAL-101 salt in an open-label crossover design. Part 4 evaluated multiple ascending doses of uncoated GAL-101 salt administered once daily for 7 days compared with placebo. Part 5 evaluated the pharmacokinetics of a single dose of uncoated GAL-101 salt compared with placebo in healthy elderly participants aged 65 to 85 years.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Treatment-Emergent Adverse Events

    Treatment-emergent adverse events, serious adverse events, adverse events of special interest, and dose-limiting toxicities were assessed after administration of GAL-101 salt or placebo. Events were evaluated by severity and relationship to the study intervention.

    From the first dose through 28 days after the participant's last dose
