Study 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.Condition or Disease | Intervention/Treatment |

Outcome Measures
Primary Outcome Measures
- Change from baseline to week 8 in the Positive and Negative Syndrome Scale (PANSS) total score [Baseline, Week 8] 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.
Secondary Outcome Measures
- Change in Clinical Global Impression-Severity (CGI-S) scale score from baseline to week 8 [Baseline, 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.
- Change in Personal and Social Performance Scale (PSP) score from baseline to week 8 [Baseline, 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).
- Number of participants reporting at least one Adverse Event [Baseline to Week 8] 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.
- Number of participants reporting at least one Adverse Event [Week 8 to Week 60] 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.
- Change in total PANSS score from baseline to weeks 1, 2, and 4 [Baseline, Week 1, Week 2, Week 4]
- Change in Clinical Global Impression-Improvement (CGI-I) scale score from baseline to weeks 4 and 8 [Baseline, Week 4, Week 8] CGI-I scores range from 1 to 7: 0=not assessed (missing), 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse.
- Change in CGI-S scale score from baseline to weeks 1, 2, and 4 [Baseline, Week 1, Week 2, Week 4]
- Change in Patient Global Impression-Improvement (PGI-I) scale score from baseline to week 8 [Baseline, Week 8] The PGI-I score ranges from 1 (Very much better) through to 7 (Very much worse). The lower the score, the better the improvement.
- Change in PGI-I scale score from baseline to weeks 2 and 4 [Baseline, Week 2, Week 4]
- Change in Schizophrenia Quality of Life Scale (SQLS) score from baseline to weeks 4 and 8 [Baseline, Week 4, Week 8] The SQLS questionnaire assesses schizophrenia quality of life. A higher score indicates worse quality of life.
- Change in PSP score from baseline to week 4 [Baseline, Week 4]
- Number of participants reporting use of at least one Concomitant Medication [Baseline to Week 8]
- Number of participants reporting use of at least one Concomitant Medication [Week 8 to Week 60]
- Number of participants that discontinued the trial [Baseline to Week 8]
- Number of participants that discontinued the trial [Week 8 to Week 60]
- Number of participants who Discontinued the trial due to Adverse Events [Baseline to Week 8]
- Number of participants who Discontinued the trial due to Adverse Events [Week 8 to Week 60]
- Change from Baseline in Abnormal Involuntary Movement Scale (AIMS) total score [Baseline to Week 8]
- Change from Baseline in total score in Abnormal Involuntary Movement Scale (AIMS) [Week 8 to Week 60]
- Change from baseline in Simpson-Angus Scale (SAS) mean score [Baseline to Week 8]
- Change from baseline in Simpson-Angus Scale (SAS) mean score [Week 8 to Week 60]
- Change from baseline in Barnes Akathisia Rating Scale (BARS) total score [Baseline to Week 8]
- Change from baseline in Barnes Akathisia Rating Scale (BARS) total score [Week 8 to Week 60]
- Number of participants with any suicidal ideation or suicidal behavior according to the Columbia Suicide Severity Rating Scale (C-SSRS) [Baseline to Week 8]
- Number of participants with any suicidal ideation or suicidal behavior according to the Columbia Suicide Severity Rating Scale (C-SSRS) [Week 8 to Week 60]
- Change from baseline in Calgary Depression Scale for Schizophrenia (CDSS) [Baseline to Week 8]
- Change from baseline in Calgary Depression Scale for Schizophrenia (CDSS) [Week 8 to Week 60]
