A Study Comparing LTG-001 SDD Formulation To LTG-001 Crystalline Immediate Release Tablets In Healthy Participants

Completed · Phase 1

Conditions studied: Pain Management

In brief

This is a single-center, open-label, part-randomized, crossover study in 14 healthy participants to assess the PK and safety profile of an SDD formulation of LTG-001 and two crystalline LTG-001 Instant Release tablet formulations, one of which will also be assessed at a differing dose level.
