Among the 1,937 studies in Alzheimer Disease with a site in United States, from their registry updates:
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.
Key Inclusion Criteria:
Willing and able to provide written , or, if deemed lacking in the capacity to provide informed consent, the following requirements for consent must be met:
Has a NPI-C H+D score of ≥ 6 AND meet at least 1 of the following 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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Change from Baseline to End of Treatment in the Neuropsychiatric Inventory-Clinician: Hallucinations and Delusions (NPI-C H+D) score
NPI-C H+D scale includes 2 domains from the NPI-C scale, namely, hallucinations and delusions. These 2 domains include the following number of items to be rated by the clinician: Hallucinations, 7 items (maximum score = 21) and Delusions, 8 items (maximum score = 24). The maximum score for the NPI-C: H+D scale is 45. Higher scores on this scale indicate worse outcomes.
Time frame: Baseline and End of Treatment (7 weeks)
Change from Baseline to End of Treatment in the Clinical Global Impressions-Severity (CGI-S) hallucinations and delusions domain-specific score
The CGI-S scale is a clinician-rated, 7-point scale that is designed to rate the severity of the participant's hallucinations and delusions using the investigator's judgment and past experience with participants who have Alzheimer's disease psychosis. Higher scores on this scale indicate worse outcomes.
Time frame: Baseline and End of Treatment (7 weeks)
Change from Baseline to End of Treatment in the Neuropsychiatric Inventory - Clinician Agitation and Aggression (NPI-C A+A) score in participants who have a CGI-S agitation/aggression domain-specific score of ≥4 at Baseline
NPI-C A+A scale includes 2 domains from the NPI-C scale, namely, agitation and aggression. These 2 domains include the following number of items to be rated by the clinician: Agitation, 13 items (maximum score = 39), and Aggression, 8 items (maximum score = 24). The maximum score for the NPI-C A+A scale is 63. Higher scores on this scale indicate more severe symptoms of agitation and aggression.
Time frame: Baseline and End of Treatment (7 weeks)

Started Aug 2025 (actual). Primary completion is estimated for Dec 2027, 28 months after the start.
Of 130 industry-sponsored phase 2 interventional studies under Alzheimer Disease, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 39. This study's planned 28 months is close to that.
Counting every sponsor, half of 257 studies reached it within 37 months; a quarter within 21 and three quarters within 58.
