This is a Phase 3, randomized, double-blind, parallel-group, active- and placebo-controlled, multicenter inpatient study to examine the efficacy and safety of HS-10380 in adult Participants who are acutely psychotic with a Diagnostic and Statistical Manual Fifth Edition (DSM-5) diagnosis of schizophrenia. The primary objective of the study is to assess the efficacy of HS-10380 versus placebo in reducing Positive and Negative Syndrome Scale (PANSS) total scores in adult inpatients with a DSM-5 diagnosis of schizophrenia. The secondary objectives of the study are to evaluate the response rate, improvement in disease severity and symptoms, safety and tolerability.
This trial is a Phase 3, randomized, double-blind, parallel-group, active- and placebo-controlled, multicenter inpatient study, aims to further evaluate the efficacy and safety of HS-10380 in participants with acute schizophrenia, who were randomized (2:2:2:1) to receive HS-10380 (1.5-3mg), HS-10380 (4.5-6mg) , placebo and aripiprazole, with the primary endpoint as the change from baseline in PANSS total score on D42.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Change from Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 6 (Day 42)
The PANSS is a medical scale used for measuring symptom severity of participants with schizophrenia. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants were rated from 1 to 7 on each symptom scale. The total score is the sum of all scales with a minimum score of 30 and a maximum score of 210. A decrease in PANSS total score correlates with an improvement in schizophrenia symptoms.
Time frame: Baseline and Week 6
Percentage of Positive and Negative Syndrome Scale (PANSS) Responders (>=30% and 50% Change in PANSS Total Score) at Day 42
The PANSS is a medical scale used for measuring symptom severity of participants with schizophrenia. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants are rated from 1 to 7 on each symptom scale. The total score is the sum of all scales with a minimum score of 30 and a maximum score of 210. A PANSS responder is defined as a participant with at least a 40% change in PANSS total score compared to baseline at D42
Time frame: Baseline and Week 6
Change in Marder 5-factor score of the PANSS scale at Day 42 compared with baseline
The Marder 5-factor model is a validated subscale classification of the Positive and Negative Syndrome Scale (PANSS), which was proposed by psychiatrist Stephen R. Marder to refine the dimensional assessment of symptom severity in schizophrenia. It divides the 30 items of the PANSS into five distinct symptom domains, namely: Positive symptoms；Negative symptoms；Disorganization symptoms；Excitement/hostility symptoms；Anxiety/depression symptoms.
Time frame: Baseline and Week 6
Change in Calgary Depression Scale for Schizophrenia (CDSS) score at Day 42 compared with baseline
The Calgary Depression Scale for Schizophrenia (CDSS) is a disease-specific, validated rating scale designed exclusively to assess depressive symptoms in patients with schizophrenia. Unlike general depression scales, it avoids overlap with schizophrenia core symptoms (e.g., anhedonia, avolition) that may mimic depressive manifestations, thus ensuring the accuracy of depression symptom evaluation in this population. The scale consists of 9 items, each rated on a 4-point Likert scale (0 = absent, 1 = mild, 2 = moderate, 3 = severe). The items cover key depressive domains including depressed mood, hopelessness, suicidal ideation, guilt feelings, insomnia, reduced appetite, early morning awakening, psychomotor retardation, and inability to feel pleasure.
Time frame: Baseline and Week 6
Change from Baseline in Clinical Global Impression-Severity (CGI-S) Score at Day 42
The CGI-S modified asked the clinician 1 question: "Considering your total clinical experience, how mentally ill is the participant at this time?" The clinician's answer rated on the following 7-point scale: 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill participants.
Time frame: Baseline and Week 6
Clinical Global Impression-Improvement (CGI-I) Score at Day 42
The Clinical Global Impression-Improvement (CGI-I) is a 7-point scale used to assess the patient's improvement relative to baseline status. The scale ranges from 1 to 7, with lower scores indicating greater improvement:1 = Very much improved;2 = Much improved;3 = Minimally improved;4 = No change;5 = Minimally worse;6 = Much worse;7 = Very much worse.
Time frame: Week 1 and Week 6
Start is estimated for Nov 2026; primary completion for Jan 2029, 26 months later.
Of 99 industry-sponsored phase 3 interventional studies under Schizophrenia, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 41. This study's planned 26 months is below that.
Counting every sponsor, half of 113 studies reached it within 32 months; a quarter within 20 and three quarters within 46.
