Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Willing and able to give informed consent/assent as per local requirements.
  • Participants are willing and able to discontinue all antipsychotic medications prior to the baseline visit, as determined by the investigator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence and severity of adverse events (AE)
Time Frame: From first dose to end of study (Up to approximately 54 weeks )
TEAEs are defined as events with an onset date on or after the first dose of HS-10380. An Adverse Event is any symptom, physical sign, syndrome, or disease that either emerges during the study or, if present at baseline, worsens during the study, regardless of the suspected cause of the event.
From first dose to end of study (Up to approximately 54 weeks )
Incidence and severity of serious adverse events (SAE)
Time Frame: From first dose to end of study (Up to approximately 52 weeks)
An SAE is any untoward medical occurrence, in the view of either the investigator or sponsor, that results in death; is life-threatening; results in inpatient hospitalization or prolongation of existing hospitalization ; results in persistent or significant disability/incapacity, and/or; is a congenital anomaly/birth defect.
From first dose to end of study (Up to approximately 52 weeks)
Incidence of Treatment-Emergent Adverse Events (TEAE) Leading to Study Drug Discontinuation
Time Frame: From first dose to end of study (Up to approximately 54 weeks )
TEAEs are defined as events with an onset date on or after the first dose of HS-10380. An Adverse Event is any symptom, physical sign, syndrome, or disease that either emerges during the study or, if present at baseline, worsens during the study, regardless of the suspected cause of the event.
From first dose to end of study (Up to approximately 54 weeks )

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score
Time Frame: Open-label extension baseline, week 52
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 positive symptoms in schizophrenia are the excess or distortion of normal function and the negative symptoms are the diminution or loss of normal functions . PANSS total score is the sum of all 30 items with a minimum score of 30 and a maximum score of 210. Higher scores indicate more severe symptoms.
Open-label extension baseline, week 52
Change from Baseline in Clinical Global Impression-Severity (CGI-S) Score
Time Frame: Open-label extension baseline, week 52
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.
