Phase 1

Not yet recruiting

• Conditions: Pain
• Interventions: Drug: Placebo; Drug: SRP-3D (diethylamide)

• Registration Number: NCT05484414
• Lead Sponsor: South Rampart Pharma, LLC

Brief Summary

This is a two-part randomized, double-blind, placebo-controlled study.

Detailed Description

This is a two-part randomized, double-blind, placebo-controlled study. The study comprises a SAD (Part 1) assessment which will include a food effect assessment that contributes data to inform a subsequent MAD (Part 2) dose-ranging study. Safety measurements will be collected throughout the study for all subjects. Blood samples will be collected to determine the PK parameters of SRP-3D (DA).
