Clinical Trial Summary

The primary objective of this study is to evaluate the efficacy of TV-44749 in adult participants with schizophrenia.

A key secondary objective is to further evaluate the efficacy of TV-44749 based on additional parameters in adult participants with schizophrenia.

A secondary objective is to evaluate the safety and tolerability of TV-44749 in adult participants with schizophrenia

Another secondary objective of this study is to evaluate the efficacy of TV-44749 from baseline to endpoint in Period 1 in adult participants with schizophrenia.

Total study duration is up to 61 weeks, and treatment duration is up to 56 weeks, with weekly visits during the first 8 weeks and then monthly in-clinic visits with weekly calls during the remainder of the treatment period.

Description:

Participants with exacerbation of schizophrenia may be included. The study will be composed of 2 periods: Period 1 (the double-blind, placebo-controlled, efficacy and safety period) and Period 2 (open-label long term safety period). For each participant, the duration of Period 1 will be 8 weeks, and the duration of Period 2 will be up to 48 weeks. In Period 1, participants will be randomized to one of 3 TV-44749 treatment groups or a placebo group in a 1:1:1:1 ratio. All participants will be randomized again to one of the TV44749 treatment groups in a 1:1:1 ratio for Period 2. The end-of-treatment and follow-up visits will be at 4 and 8 weeks after the last dose of investigational medicinal product administration, respectively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline to week 8 in the Positive and Negative Syndrome Scale (PANSS) total score	Data gathered from this assessment procedure are applied to the PANSS ratings. Each of the 30 items is accompanied by a specific definition as well as detailed anchoring criteria for all seven rating points. These seven points represent increasing levels of psychopathology, as follows: 1- absent 2- minimal 3- mild 4- moderate 5- moderate severe 6- severe 7- extreme.	Baseline, Week 8
Secondary	Change in Clinical Global Impression-Severity (CGI-S) scale score from baseline to week 8	The CGI-S rates this severity of a 1-7 scale, with (1) representing normal symptoms, meaning the participant is not ill. The highest on the scale, (7), represents participants among the most severely ill. Right in the middle at (4), a participant will be defined as moderately ill.	Baseline, Week 8
Secondary	Change in Personal and Social Performance Scale (PSP) score from baseline to week 8	The PSP is a clinician-based rating instrument providing an overall rating of personal and social functioning in psychiatric participants on a scale of 0 (grossly impaired functioning) to 100 (excellent functioning).	Baseline, Week 8
Secondary	Number of participants reporting at least one Adverse Event	Adverse events (including serious adverse events, extrapyramidal symptoms, injection pain and other injection site reactions), vital signs (blood pressure, pulse and orthostatic changes, and temperature), body weight, lab tests and ECGs.	Baseline to Week 8
Secondary	Number of participants reporting at least one Adverse Event	Adverse events (including serious adverse events, extrapyramidal symptoms, injection pain and other injection site reactions), vital signs (blood pressure, pulse and orthostatic changes, and temperature), body weight, lab tests and ECGs.
