  Purpose
This is a first-in-human study of GSI-136, a gamma-secretase inhibitor being developed for the treatment of Alzheimer disease. This study will take place in Japan only and will provide an initial assessment of the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of GSI-136 after administration of ascending single oral doses to healthy Japanese male subjects and healthy Japanese elderly male subjects.

Condition Intervention Phase
Alzheimer Disease Healthy Drug: GSI 136 Drug: placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Ascending Single-Dose Study of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of GSI-136 Administered Orally to Healthy Japanese Male Subjects and Healthy Japanese Elderly Male Subjects

Primary Outcome Measures:
  • Safety and tolerability of GSI-136 as evaluated from reported adverse events, scheduled physical examinations, vital sign measurements, orthostatic vital sign measurements, cardiac rhythm monitoring, 12-lead ECGs, and clinical laboratory test results. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Pharmacokinetics as evaluated from the blood and urine concentrations of GSI-136; Pharmacodynamics as evaluated from the levels of select biomarkers in the blood and the administration of a visual analog scale to measure sedation effects. [ Time Frame: 6 months ]
