Phase 1 TAK-906 Single and Multiple Ascending Dose Study in Japanese Healthy Male Participants

Takeda24 enrolled

Overview

The purpose of this study is to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple oral doses of TAK-906 in Japanese healthy male participants.

The drug being tested in this study is called TAK-906. TAK-906 is being tested in healthy participants in order to evaluate safety and tolerability of single and multiple oral doses of TAK-906 in Japanese healthy male participants. The study will enroll approximately 24 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups in Cohort 1 or Cohort 3. Study drug will be administered in a double-blind manner which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need), orally, once daily on Day 1 as Single Dose Period and twice daily from Day 3 to 7 as Multiple Dose Period: * TAK-906 50 mg (Cohort 1) * TAK-906 100 mg (Cohort 2) * TAK-906 10 mg (Cohort 3) * Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient Cohort 2 will be conducted after the completion of Cohort 1. This will be conducted in Japan.

The participant is an immediate family member of or an investigational site employee, or is in a dependent relationship with an investigational site employee who is involved in the conduct of this study (example, spouse, parent, child, sibling) or may consent under duress. 4. The participant has uncontrolled, clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, gastrointestinal, or endocrine disease or other abnormality, which may impact the ability of the participant to participate in the study or potentially confound its results. 5. The participant has a history of any psychiatric disease that would interfere with the evaluation of study drug activity (prolactin concentration) or safety. 6. The participant has a history of seizure or tardive dyskinesia. 7. The participant has a history of hyperprolactinemia, pituitary adenoma, and/or hypothyroidism. 8. The participant has a family history of prolonged QT. 9. The participant has undergone previous gastric bypass surgery or currently had a gastric band fitted. 10. The participant has dysphagia and/or inability to swallow study medication whole. 11. The participant has a known hypersensitivity to any component of the TAK-906 formulation or related compounds. 12. The participant has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse within 2 years prior to the Screening visit, or is unwilling to agree to abstain from alcohol and drugs throughout the study, or has a positive urine test result for drugs of abuse or a positive alcohol screen (urine alcohol test/breath test) result for alcohol at Screening. 13. The participant has taken any excluded medication, supplements, or dietary products during the time periods listed in the Excluded Medications, Supplements, and Dietary Products table. 14. If male, the participant intends to donate sperm during the course of this study or for at least 12 weeks (84 days) after the last dose of study drug. 15. The participant has current or recent (within 24 weeks \[168 days\]) gastrointestinal disease that would be expected to influence the absorption of drugs (that is, a history of malabsorption, esophageal reflux, peptic ulcer disease, erosive esophagitis, frequent \[more than once per week\] occurrence of heartburn, or any surgical intervention). 16. The participant has a history of cancer, except basal cell carcinoma which has been in remission for at least 5 years prior to Day 1. 17. The participant has a positive test result for hepatitis B virus surface antigen (HBsAg), hepatitis C virus (HCV) antibody, human immunodeficiency virus (HIV) antibody/antigen, or serological reactions for syphilis at Screening. 18. The participant has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patch or nicotine gum) within 4 weeks (28 days) prior to the first dose of study drug. Cotinine test is positive at Screening. 19. The participant has poor peripheral venous access. 20. The participant has undergone whole blood collection of at least 200 mL within 4 weeks (28 days) or at least 400 mL within 12 weeks (84 days) prior to the start of study drug administration. 21. The participant has undergone whole blood collection of at least 800 mL in total within 52 weeks (364 days) prior to the start of study drug administration. 22. The participant has undergone blood component collection within 2 weeks (14 days) prior to the start of study drug administration. 23. The participant has a Screening or Check-in (Day -1) electrocardiogram (ECG) that was abnormal (clinically significant). 24. The participant has a QTcF of greater than (\>) 450 millisecond (msec) on the ECG at Screening, at Check-in (Day -1), or prior to the first dose of study drug (Day 1 predose). 25. The participant has abnormal Screening or Day -1 laboratory values that suggest a clinically significant underlying disease or any participant with the following lab abnormalities: * Transaminase (alanine aminotransferase \[ALT\] and/or aspartate aminotransferase \[AST\]) and/or total bilirubin \>1.5 × upper limit of normal (ULN). * Creatinine \>1.2 milligram per deciliter (mg/dL). 26.

Outcomes

Primary Outcomes

Number of Participants Who Experience at Least One Treatment-Emergent Adverse Event (TEAE)

An adverse event (AE) is defined as any untoward medical occurrence in a clinical investigation participant who has signed informed consent to participate in a study; it does not necessarily have to have a causal relationship with the treatment or study participation. A treatment-emergent adverse events (TEAE) is defined as an AE whose date of onset occurs on or after the start of study drug.

Time frame: Baseline up to Day 14

AUC∞: Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for TAK-906 and Its Metabolite M23 on Day 1 of Single Dose Period

AUC∞ is a measure of total plasma exposure to TAK-906 and its Metabolite M23 from Time 0 extrapolated to infinity, calculated using the observed value of the last quantifiable concentration.
