About

This is a study of TAK-951 for people with symptoms of nausea and vomiting. The main aims of this study in healthy adults 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.
• To check how much TAK-951 stays in the blood over time to work out the best dose.

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.

Full description

The drug being tested in this study is called TAK-951. The study evaluated the safety, tolerability and pharmacokinetics (PK) of TAK-951 in healthy participants.

The study enrolled 128 healthy participants and consisted of 2 parts: Single-rising Dose (SRD) part (13 cohorts) of sequential panel design, and Multiple-rising Dose (MRD) part (5 cohorts) of sequential panel design. Participants in each cohort were randomized to receive treatment with TAK-951 or matching placebo using SC injection, once daily on Day 1 (for SRD part) and twice daily (BID) on Days 1 through 5 (for MRD part) following a minimum fast of 8 hours.

This single center trial was conducted in the United States. The overall time to participate in this study was approximately 155 days.

Enrollment: 128 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Have a body mass index (BMI) ≥18 and ≤30.0 (kg/m^2) at the Screening Visit.

Exclusion criteria

1. The participant has a positive test result for hepatitis B surface antigen, hepatitis C virus antibody, or human immunodeficiency antibody/antigen, at the Screening Visit. Note: Participants with positive hepatitis B virus or hepatitis C virus serology may be enrolled if quantitative polymerase chain reaction for hepatitis B virus or hepatitis C virus ribonucleic acid is negative.
2. The participant had major surgery or donated or lost 1 unit of blood (approximately 500 mL) within 4 weeks before the Screening Visit.
3. Heavy consumption of alcohol within 3 months before screening (>7 drinks/week for women, >14 drinks/week for men, where 1 drink = 5 ounces [150 mL] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) or use of soft drugs (such as marijuana) within 3 months before screening, or hard drugs (such as cocaine and phencyclidine) within 1 year before Screening.
4. The participant has used nicotine-containing products (including, but not limited to, cigarettes, pipes, cigars, chewing tobacco, nicotine patch, or nicotine gum) within 28 days before check-in (Day -1) or cotinine test is positive at Screening or Day -1.
5. The participant has had 3 incidences of vasovagal syncope within the last 5 years.
6. The participant has Brugada syndrome (right bundle branch block [RBBB] pattern with ST-elevation in leads V1-V3).
7. The participant has an average semirecumbent systolic blood pressure <90 millimeters of mercury (mm Hg) or diastolic blood pressure <60 mm Hg at Screening or admission.
8. The participant has an average heart rate (HR) <60 or >100 beats per minute (bpm) [at Screening, at Day -1, or at predose]; athletic participants with an average HR <60 bpm can be enrolled only with medical monitor approval.
9. The participant has orthostatic hypotension defined as a decrease in systolic blood pressure ≥20 mm Hg or a decrease in diastolic blood pressure ≥10 mm Hg after 2 minutes of standing when compared with blood pressure from the sitting position at Screening, and at Day -1. Participants with postural orthostatic tachycardia, defined as HR >120 bpm standing, will also be excluded.
