Phase 1, TAK-915-1001, Single-Rising Dose, Multiple-Rising Dose, Drug-Drug Interaction, Relative Bioavailability, Food Effect, and Effect on Elderly Participants Study

Healthy Volunteers Clinical Trial

Official title: A Phase 1 Safety, Tolerability, Pharmacokinetic, Placebo-Controlled and Open-Label Study of Escalating Single and Multiple Oral Doses, Drug-Drug Interaction, Relative Bioavailability, Food Effect, and Effect on Elderly Subjects of TAK-915 in Healthy Subjects

Status Completed

Clinical Trial Summary

The purpose of this study is to characterize the safety, tolerability and plasma pharmacokinetic (PK) profile of TAK-915 when administered as single and multiple oral suspension doses at escalating dose levels in healthy participants, including elderly participants.

Clinical Trial Description

The drug being tested in this study is called TAK-915. TAK-915 is being tested to find a safe and well-tolerated dose. This study will look at the pharmacokinetic characteristics (how the drug acts throughout the body) of the drug and safety and tolerability (lab results, vital signs, ECG, and side effects) in healthy people (including elderly) who take TAK-915.

The study will enroll a total of 88 patients. This study is designed to consist of 5 different dosing schedules: single rising dose (SRD), multiple rising dose (MRD), drug-drug interaction (DDI), bioavailability and food effect (BA/FE), and Elderly Subject Single Dose (ESSD). The study population for SRD will consist of 48 participants enrolled into 6 cohorts. Each cohort will have 8 randomized participants, with 6 receiving a single dose of TAK-915, and 2 receiving matching placebo under fasted conditions. The starting dose is 30 mg. The dose for Cohorts 2 through 6 will be determined based on data collected from previous cohorts.

The study population for MRD will consist of 32 participants enrolled into 4 cohorts. Each cohort will have 8 randomized participants, with 6 receiving one dose of TAK-915 on Day 1 and daily dosing on Days 8-14, and 2 receiving matching placebo under fasted conditions. The dose for each cohort in Part 2 will be determined based on data collected from completed SRD cohorts of the study.

The study population for DDI will consist of 12 participants enrolled into 1 cohort. All participants will receive one dose of TAK-915 on Day 3 and daily dosing on Days 10-16 under fasted conditions. All participants will also receive a single dose of Midazolam 2 mg on Day 1 and Day 16. The dose of TAK-915 in this cohort will be determined based on data collected from SRD cohorts and will be the same dose that is administered in MRD Cohort 8.

The study population for BA/FE will consist of 12 participants enrolled into 1 cohort. TAK-915 will be administered in 3 single-dose regimens in a 3-way crossover design using 50 mg oral dose treatments (Regimen A: TAK915 50 mg oral suspension formulation in fasted state; Regimen B: TAK-915 50 tablet formulation in fasted state; Regimen C: TAK-915 50 tablet formulation in fasted state). TAK-915 dosing will occur on Day 1 of each treatment period followed by a 14 day washout period.

The study population for ESSD will consist of 8 elderly participants (ages 65-75 years) enrolled into 1 cohort. All 8 participants will receive a single dose of TAK-915 50 mg suspension under fasted conditions.

This single-center trial will be conducted in the United States. The overall time to participate in this study is up to 70 days. Participants will make multiple visits to the clinic including a period of confinement to the clinic and will be contacted by telephone 12 days after the last dose of study drug for a follow-up assessment. ;
