Clinical Trial Summary

The purpose of the study is to assess the safety and tolerability in healthy overweight and obese volunteers administered single or multiple repeated doses of ALT-801. This study has 2 parts. Part 1 involves a single dose of ALT-801 taken as a subcutaneous (SC) injection and will be approximately 36 days in duration. Part 2 involves 12 doses of ALT-801, once a week for 12 weeks, as a SC injection and will be approximately 116 days in duration. Each participant will enroll in only one part.
