Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

An eight week, randomized, placebo controlled trial to assess subjective changes in mood and anxiety symptoms from baseline to after MET-2 treatment in participants with depression, using MADRS, Hamilton Anxiety Rating Scale (HAM-A), and other mood/anxiety scales and to demonstrate a significantly higher proportion of responders in patient who were randomized to receive the active study drug compared to patients who were randomized to receive placebo.

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.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: MET-2 20 g
Loading dose of MET-2 is administered for the first two days, followed by a regular, daily dose for the duration of the study (6 weeks total).The loading dose will consist of 5 g of MET-2 in the form of ten capsules orally on day one and on day two. The regular daily dose will consist of 1.5 g MET-2 in the form of three MET-2 capsules taken once daily, excluding days where they take the booster (same as loading dose).
Drug: MET-2
Subjects will take capsules containing MET-2 daily during the trial. There will be a loading dose at the start of dosing, and a daily dose. There will be a booster dose given at week 2 and a second booster dose taken at week 4 for those subjects who have not improved by that time.
PLACEBO_COMPARATOR: Placebo
Loading dose of placebo is administered for the first two days, followed by a regular, daily dose of placebo for the duration of the study (6 weeks total).The loading dose will consist of ten capsules of placebo (which match the MET-2 capsules in appearance and weight) taken orally on day one and on day two. The regular daily dose will consist of three placebo capsules taken once daily, excluding days where they take the booster (same as loading dose).
Drug: Placebo
