Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the safety and tolerability of TAK-831 when administered as multiple oral doses at escalating dose levels in healthy participants.

Condition or Disease Intervention/Treatment Phase
  • Drug: TAK-831 Tablet T2
  • Drug: Placebo
  • Drug: TAK-831 Suspension
Phase 1

Detailed Description

This study is a randomized, investigator and participant blinded, sponsor unblinded, placebo-controlled, study of the safety, tolerability and pharmacokinetics of TAK-831 in up to 48 healthy volunteers, with 8 subjects in each of the 6 cohorts.

In each cohort, participants will be randomized in a 3:1 ratio to receive TAK-831 or placebo. Two formulations, oral suspension and tablet will be tested in this study. Both blood and cerebrospinal fluid (CSF) samples will be collected from selected cohorts (CSF cohorts); for the rest of the cohorts, only blood samples will be collected (non-CSF cohorts).

This single-center trial will be conducted in the United States. The overall time to participate in this study is 58 days. Participants will make multiple visits to the clinic, and 30 days after last dose of study drug for a follow-up assessment.

Outcome Measures

Primary Outcome Measures

  1. Percentage of Participants Who Experienced at Least 1 Treatment-Emergent Adverse Event (TEAE) [Baseline up to 30 days after the last dose (Up to 48 days)]

    An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an AE with an onset that occurs after receiving study drug.

  2. Percentage of Participants Who Met the Markedly Abnormal Criteria for Safety Laboratory Tests at Least Once Postdose [Baseline up to 30 days after the last dose (Up to 48 days)]

    Clinical Laboratory parameters included tests for chemistry, hematology and urinalysis. Markedly abnormal values during treatment period were categorized as: alanine aminotransferase (ALT)>3.0 U/L*upper limit of normal(ULN), albumin<25 g/L, alkaline phosphatase >3.0 U/L*ULN, aspartate aminotransferase >3.0 U/L*ULN, bilirubin >3.42 umol/L creatinine >177umol/L, gamma glutamyl transferase (GGT) >3 U/L*ULN, glucose <2.8 mmol/L, >19.4 mmol/L, potassium<3 mmol/L, >6 mmol/L, sodium <130 mmol/L, >150 mmol/L, protein <0.8 g/L,* lower limit of normal (LLN), >1.2 g/L*ULN, erythrocytes <0.8 (10^12/L)*LLN, >1.2 (10^12/L)*ULN, hematocrit (%) <0.8*LLN, >1.2*ULN, hemoglobin <0.8 g/L*LLN, >1.2 g/L*ULN, leukocytes <0.5 (10^9/L)*LLN, >1.5 (10^9/L)*ULN, platelets <75(10^9/L), >600(10^9/L). Only categories with values have been reported.

  3. Percentage of Participants Who Met the Markedly Abnormal Criteria for Vital Sign Measurements at Least Once Postdose [Baseline up to 30 days after the last dose (Up to 48 days)]

    Vital signs included temperature, pulse rate and blood pressure. Markedly abnormal values during treatment period were categorized as: Pulse Rate (beats/min) <50->120, Systolic Blood Pressure (SBP) (mmHg) <85->180, Diastolic Blood Pressure (DBP) (mmHg) <50->110 and Temperature (degree centigrades) <35.6- >37.7.

  4. Percentage of Participants Who Met the Markedly Abnormal Criteria for Safety Electrocardiogram (ECG) Parameters at Least Once Postdose [Baseline up to 30 days after the last dose (Up to 48 days)]

    A 12-lead ECG was performed. Markedly abnormal values during treatment period were categorized as: ECG Mean Heart Rate (beats/min) <50->120, PR Interval, Aggregate (msec) <=80->=200, QRS Duration, Aggregate (msec) <=80->=180, QT Interval, Aggregate (msec) <=300->=460, QTcF Interval, Aggregate (msec) <=300->=500 OR >=30 change from baseline and >=450 milliseconds.

Secondary Outcome Measures

  1. Cmax: Maximum Observed Plasma Concentration for TAK-831 [0.5 hours pre-dose and at multiple timepoint (Up to 24 hours) post-dose on Day 1]

  2. Cmax ss: Maximum Observed Steady-state Plasma Concentration During a Dosing Interval for TAK-831 [0.5 hours pre-dose and at multiple timepoint (Up to 24 hours) post-dose on Day 16]

  3. Tmax: Time of First Occurrence of Cmax for TAK-831 [0.5 hours pre-dose and at multiple timepoint (Up to 24 hours) post-dose on Days 1 and 16]

  4. AUC0-24: Area Under the Plasma Concentration-time Curve During a Dosing Interval for TAK-831 [0.5 hours pre-dose and at multiple timepoint (Up to 24 hours) post-dose on Days 1 and 16]
