A Study of TAK-951 in Healthy Adults

Healthy Volunteer Clinical Trial

Official title: A Randomized, Double-Blind, Placebo-Controlled, Phase 1 Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of TAK-951 in Healthy Subjects Following Intravenous Administration

Status Completed

Clinical Trial Summary

It is hoped that a medicine called TAK-951 will eventually be used to treat nausea and vomiting. Before then, the sponsor needs to understand how the body processes TAK-951 in healthy adults.

The main aims of this study are as follows:

• To check for side effects from TAK-951 when given at a slow and fast infusion rate.

• To learn how much TAK-951 participants can receive without getting side effects from it.

Participants will receive a single infusion of either TAK-951 or placebo. In this study, a placebo looks like TAK-951 but does not have any medicine in it. Participants will receive either a low dose or high dose of TAK-951. The infusion will take from 1-3 hours.

Participants will stay in the study clinic for about 4 days to receive the study medicine (TAK-951 or placebo) and check for side effects. They will have follow-up visits at the clinic about 2 weeks and 4 weeks after treatment.

Clinical Trial Description

The drug being tested in this study is called TAK-951. The study will evaluate the safety, tolerability and PK of TAK-951 in healthy participants.

The study will enroll approximately 40 healthy participants. Each cohort will have 8 participants to be randomized and a minimum of 3 cohorts will be evaluated. Participants will be randomly assigned (by chance, like flipping a coin) to receive TAK-951 or placebo in a 6:2 ratio in one of the following 3 cohorts, which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):

• Cohort 1 (Low Dose): TAK-951 20 mcg Infusion Over 60 Minutes

• Cohort 2 (High Dose): TAK-951 1 mg Infusion Over 60 Minutes

• Cohort 3: TAK-951 1 mg Infusion over 120 Minutes

Sentinel dosing will be done in first 2 participants in each cohort. The dosing in rest of the cohort will done if there are no significant safety or tolerability concerns. Additional 2 cohorts, each cohort with 8 participants may be added in study to evaluate additional intravenous dosing regimen after clinical data analysis of first 3 cohorts. Dosing of the subsequent cohort will be based on the analysis of the previous cohort's data.

This single-center trial will be conducted in the United States. The overall time to participate in this study is up to 57 days. All participants will return to clinic after 14 and 28 days after the last visit to the clinic for a follow-up assessment. ;
