Study Endpoints

Primary Endpoints

Number of Participants with Incidence of adverse events
From first dose through dosing period until 7 days post last dose
Number of Participants With Clinically Significant Clinical Laboratory Abnormalities
From baseline through end of study visit

Clinical laboratory assessments include urinalysis and blood tests. Clinically significant laboratory abnormality is determined by the investigator.

Number of Participants With Clinically Significant Vital Sign Abnormalities
From baseline through end of study visit

Vital sign assessments include blood pressure, heart rate, respiratory rate, and oral temperature. Clinically significant vital sign abnormality is determined by the investigator.

Number of Participants With Clinically Significant Electrocardiogram (ECG) Abnormalities on a 12-Lead ECG
From baseline through end of study visit

Safety ECG will be assessed using 12-lead ECG recordings. Clinically significant abnormality is determined by the investigator.

Number of Participants With Clinically Significant Physical Examination Findings
From baseline through end of study visit

A focused physical examination will be performed prior to dosing on Day 1 and upon discharge on Day 2. For cohorts 5-7, a focused physical examination will be performed prior to dosing on Day 1, on Day 3, and Day 6. Examination of the cardiovascular system is mandatory, while the other body systems will be examined at the discretion of the Principal Investigator.

Number of Participants With Ketamine-Related Side Effects as Assessed by the Ketamine Side Effect Tool (KSET)
From baseline through end of study visit

The Ketamine Side Effect Tool will be used to assess ketamine-related side effects.

Change From Baseline in Bowdle Visual Analog Scale (VAS) Score
From baseline through end of study visit

The Bowdle VAS is a tool used to measure the psychedelic effects of substances. It consists of 13 items (each scored on 0-100 mm) that assess both internal perception and external perception. Higher scores indicate greater subjective effects.

ArmTypeDescription
Cohort 1: Single Dose Ketamir-2 50 mg or PlaceboEXPERIMENTALParticipants in Cohort 1 were randomized in a 3:1 ratio to receive a single oral dose of Ketamir-2 50 mg or matching placebo on Day 1. Ketamir-2 was administered as one 50 mg capsule. Matching placebo was administered as one capsule.
Cohort 2: Single Dose Ketamir-2 150 mg or PlaceboEXPERIMENTALParticipants in Cohort 2 were randomized in a 3:1 ratio to receive a single oral dose of Ketamir-2 150 mg or matching placebo on Day 1. Ketamir-2 was administered as three 50 mg capsules. Matching placebo was administered as three capsules.
Cohort 3: Single Dose Ketamir-2 300 mg or PlaceboEXPERIMENTALParticipants in Cohort 3 were randomized in a 3:1 ratio to receive a single oral dose of Ketamir-2 300 mg or matching placebo on Day 1. Ketamir-2 was administered as one 300 mg capsule. Matching placebo was administered as one capsule.
Cohort 4: Single Dose Ketamir-2 600 mg or PlaceboEXPERIMENTALParticipants in Cohort 4 were randomized in a 3:1 ratio to receive a single oral dose of Ketamir-2 600 mg or matching placebo on Day 1. Ketamir-2 was administered as two 300 mg capsules. Matching placebo was administered as two capsules.
Cohort 5: Ketamir-2 150 mg Once Daily for 5 Days or PlaceboEXPERIMENTALParticipants in Cohort 5 were randomized in a 3:1 ratio to receive Ketamir-2 150 mg or matching placebo once daily for 5 days, from Day 1 through Day 5. Ketamir-2 was administered as three 50 mg capsules once daily. Matching placebo was administered as three capsules once daily.
Cohort 6: Ketamir-2 300 mg Once Daily for 5 Days or PlaceboEXPERIMENTALParticipants in Cohort 6 were randomized in a 3:1 ratio to receive Ketamir-2 300 mg or matching placebo once daily for 5 days, from Day 1 through Day 5. Ketamir-2 was administered as one 300 mg capsule once daily. Matching placebo was administered as one capsule once daily.
Cohort 7: Ketamir-2 600 mg Once Daily for 5 Days or PlaceboEXPERIMENTALParticipants in Cohort 7 were randomized in a 3:1 ratio to receive Ketamir-2 600 mg or matching placebo once daily for 5 days, from Day 1 through Day 5. Ketamir-2 was administered as two 300 mg capsules once daily. Matching placebo was administered as two capsules once daily.

Interventions

NameTypeDescription
Ketamir-2DRUGKetamir-2, also referred to as Ketamir hemipamoate, was administered orally as capsules containing 50 mg or 300 mg. Participants randomized to active treatment received Ketamir-2 according to assigned dose cohort. Cohorts 1 through 4 received a single dose on Day 1. Cohorts 5 through 7 received once-daily dosing from Day 1 through Day 5. Capsules were swallowed together with a glass of water after an overnight fast.
PlaceboDRUGPlacebo capsules were identical in appearance to active capsules and were administered orally according to the same number of capsules and dosing schedule as the corresponding Ketamir-2 dose cohort.
