Phase 1 Study Accessing the Safety and Tolerability of CBP-307

Phase 1

Completed

• Conditions: Autoimmune Diseases
• Interventions: Drug: Placebo; Drug: CBP-307

• Registration Number: NCT02280434
• Lead Sponsor: Suzhou Connect Biopharmaceuticals, Ltd.

Brief Summary

This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of CBP-307 following oral single and multiple escalating dose administration in healthy subjects.

Detailed Description

This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of CBP-307 following oral single and multiple escalating dose administration in healthy subjects. The study will have two parts: Part 1 will assess 5 dose levels of the drug in single dosing; and Part 2 will evaluate 3 dose levels in 28-day repeat dosing. The effect of food will also be evaluated in a single dosing study.
