Details and patient eligibility

About

ML-007C-MA-221 is a Phase 2, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of ML-007C-MA in male and female participants aged 55 to 90 years with hallucinations and delusions associated with Alzheimer's Disease Psychosis (ADP).

The primary objective is to evaluate the efficacy of ML-007C-MA compared with placebo for the treatment of hallucinations and delusions associated with ADP as measured by the Neuropsychiatric Inventory-Clinician (NPI-C): Hallucinations and Delusions (H+D) score.

  6. Has a designated care partner who is in contact with the participant frequently enough to accurately report on the participant's symptoms and adherence to study drug.

  7. Has a NPI-C H+D score of ≥ 6 AND meet at least 1 of the following criteria:

    1. Moderate to severe delusions, defined as NPI-C Delusions domain score of ≥ 2 on at least 2 of the 8 items OR
    2. Moderate to severe hallucinations, defined as NPI-C Hallucinations domain score of ≥ 2 on at least 2 of the 7 items.
  8. Has a (CGI)-S hallucinations and delusions domain-specific score ≥4

  9. Has an Mini-mental State Examination (MMSE) score of 6 to 26, inclusive.

  4. Moderate or severe major depressive episode within 3 months of Screening, according to DSM-5 criteria.
  5. Has had an amyloid positron emission tomography (PET) brain scan or cerebrospinal fluid (CSF) Alzheimer's disease biomarker test in the past 3 years with results inconsistent with a diagnosis of AD.
  6. Evidence of a clinically significant and/or unstable medical condition that, in the opinion of the investigator or medical monitor, could substantially impair cognition, compromise participant safety, interfere with the participant's ability to comply with study procedures or substantially impair the evaluation of efficacy or safety assessments.
  7. Gastric retention, urinary retention or narrow-angle (angle-closure) glaucoma
  8. Meets or has met DSM-5 criteria for alcohol or substance use disorder within the past 12 months (excluding caffeine and nicotine).
