What is being measured
The primary outcome is the main question the study is designed to answer.
Dose Response
To investigate the dose-response relationship for different doses of MM120 versus placebo in change from Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score at Week 4. The HAM-A consists of the following 14 items that encompass both psychological and somatic symptoms of anxiety: Anxious mood, Tension, Fears, Insomnia, Intellectual, Depressed mood, Somatic (muscular), Somatic (sensory), Cardiovascular symptoms, Respiratory symptoms, Gastrointestinal symptoms, Genitourinary symptoms, Autonomic symptoms, and Behavior at interview (general). The central rater assessed the extent to which the subject displayed each given criterion and gave a rating on a scale of 0-4, where 4 represents the most severe symptoms. Minimum score = 0, maximum score = 56. Scores are summed and the greater the total score, the more severe illness.
Measured: 4 weeks

The Sheehan Disability Scale (SDS) is a composite of 3 self-rated items designed to measure the extent to which 3 major domains in the patient's life (work, social life/leisure activities and family life/home responsibilities) are functionally impaired by psychiatric or medical symptoms. Total score 0-30 (0 unimpaired, 30 highly impaired). Work/school (0-10); Social life (0-10); Family life/home responsibilities (0-10).

The EuroQol 5 Dimension 5 Level (EQ-5D-5L) was used to evaluate health outcomes over a wide range of health conditions and treatments. The EQ-5D consists of the EQ-5D descriptive system and the EQ visual analogue scale (VAS). The VAS for the subject's health status scored as ranging from 0 = worst health you can imagine, to 100 = best health you can imagine.

The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality and disturbances over the preceding month. The questionnaire had a Component Score for each of these with a range of 0-3 points: Subjective sleep quality, Sleep latency, Sleep duration, Habitual sleep efficiency, Sleep disturbance, Use of sleeping medication, and Daytime dysfunction. The sum of the Component Scores = a Global Score. Global Score of 0 indicated no difficulty and a Global Score of 21 indicated severe difficulty in all areas.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a Phase 2, multi-center, randomized, double-blind, parallel-group, dose-finding study to assess the effect of 4 doses of MM120 (25, 50, 100 or 200 μg freebase-equivalent) for the treatment of anxiety symptoms in subjects diagnosed with generalized anxiety disorder (GAD).
Detailed description
The study will enroll approximately 200 male and female subjects 18 years to < 75 years of age who meet DSM-5 criteria for GAD and have a minimum HAM-A Total Score of 20. Subjects on contraindicated concomitant medications, supplements or other therapeutics at Screening (Visit 1) will undergo a medication taper prior to advancing to Baseline (Visit 2).

Primary outcome
Dose Response
Time frame: 4 weeks
To investigate the dose-response relationship for different doses of MM120 versus placebo in change from Baseline in Hamilton Anxiety Rating Scale (HAM-A) Total Score at Week 4. The HAM-A consists of the following 14 items that encompass both psychological and somatic symptoms of anxiety: Anxious mood, Tension, Fears, Insomnia, Intellectual, Depressed mood, Somatic (muscular), Somatic (sensory), Cardiovascular symptoms, Respiratory symptoms, Gastrointestinal symptoms, Genitourinary symptoms, Autonomic symptoms, and Behavior at interview (general). The central rater assessed the extent to which the subject displayed each given criterion and gave a rating on a scale of 0-4, where 4 represents the most severe symptoms. Minimum score = 0, maximum score = 56. Scores are summed and the greater the total score, the more severe illness.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose Response (time frame: 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
