Clinical Trial Summary

Primary Objective:

To evaluate the safety and tolerability of single doses of TV-44749 for subcutaneous (sc) use in Chinese participants with schizophrenia.

Secondary Objectives:

• To evaluate the pharmacokinetics (PK) of single doses of TV-44749 administered sc.

• To evaluate the pharmacokinetics of oral olanzapine tablets following multiple dose administration.

• To monitor the safety and tolerability of multiple doses of oral olanzapine tablets given in the study.

Description:

The total study duration for participants is planned to be approximately 13 weeks, including 40 days of screening, 1-week oral olanzapine treatment, a 1-week washout period, 4-week TV-44749 treatment, and 2-week follow-up period after the last dosing interval.
