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.

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

Description

Key Inclusion Criteria:

  1. Must be able and willing to provide informed consent for all required study procedures.
  2. Has a primary diagnosis of schizophrenia based on the DSM-5 criteria that is confirmed by semi-structured clinical interview (Mini International Neuropsychiatric Interview for DSM-5).
  3. May benefit from long-term pharmacotherapy for schizophrenia, based on assessment of the investigator.
  4. Is appropriate for an outpatient level of care and resides in a stable living situation, based on assessment of the investigator.
  5. Has an identified reliable informant(s) available to participate in relevant assessments. Site staff may serve as the informant if the site has had regular contact with the participant for >1 year.

Key Exclusion Criteria:

  1. Has any DSM-5 disorder, other than schizophrenia, within the 12 months before Screening that is primarily responsible for the current symptoms or functional impairment.
  2. Is discontinuing effective and well-tolerated antipsychotic therapy for the purpose of enrolling in this study.
  3. Has received any prohibited therapy within the Screening Period unless discontinued before Baseline.
  4. Has current evidence of a clinically significant and/or unstable medical comorbidity at Screening or Baseline.
  5. Has clinically significant abnormal physical examination, ECG, or clinical safety laboratory result at Screening or Baseline.
  6. Has an elevated risk of suicidal behavior.
  7. Has a known allergy to ML-007C-MA, its active ingredients or their excipients.
  8. Has a DSM-5 diagnosis of moderate to severe substance use disorder (except tobacco or caffeine use disorder) within the 12 months before Screening (confirmed using MINI version 7.0.2 at Screening).
  9. Has an elevated risk of violent or destructive behavior, based on participant history and investigator judgment.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
