简要总结

Trial to determine the maximum tolerated dose (MTD) based on safety and tolerability of MK-8777 (Org 26576, SCH 900777) in participants with major depressive disorder.

详细描述

This is a randomized, placebo-controlled, safety and tolerability study examining MK-8777 in participants with major depressive disorder. In Part I of the trial, four different cohorts of six participants each will receive multiple rising doses of MK-8777 (ranging from 100 mg twice a day [BID] to 300 mg BID) or placebo for up to 16 days. In Part 2, a new cohort of participants will be randomly assigned to receive 100 mg BID of MK-8777, 400 mg BID of MK-8777, or placebo. Following titration (3 days per step), participants will be maintained on the assigned BID dose until Day 27, followed by one day of once a day (QD) dosing, for a total of 28 days. There were 11 treatment arms in total for Part 1 and Part 2 (see Interventions).

结局指标

主要结局

Part 1: Number of Participants With Serious Adverse Events (SAEs)

时间窗: Up to 30 days following the last dose of study drug (Up to 46 days)

An SAE is defined as any untoward medical occurrence that at any dose: results in death, is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect.

Part 1: Number of Participants With Moderate Intensity Adverse Events (AEs)

时间窗: Up to 7 days following the last dose of study drug (Up to 23 days)

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. A moderate intensity AE is defined as an AE that causes no significant interference with functioning.

Part 1: Number of Participants With AEs Leading to Discontinuation of Study Drug

时间窗: Up to the last dose of study drug (Up to 16 days)

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. Discontinuation refers to discontinuation of study drug (MK-8777 or Placebo).

Part 2: Number of Participants With AEs

时间窗: Up to 7 days following the last dose of study drug (Up to 35 days)

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product.

Part 2: Number of Participants With AEs Leading to Discontinuation of Study Drug

时间窗: Up to the last dose of study drug (Up to 28 days)

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. Discontinuation refers to discontinuation of study drug (MK-8777 or Placebo).

次要结局

  • Part 1: Change From Baseline in the Montgomery-Ashberg Depression Rating Scale (MADRS)(Baseline and end of treatment (Up to Day 16))
  • Part 2: Change From Baseline in the MADRS(Baseline and end of treatment (Up to Day 28))
