About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Single and Multiple Ascending Dose, Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of TAK-906 in Japanese Healthy Male Subjects
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.
Read the detailed description
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
Detailed description
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.

Primary outcome
Number of Participants Who Experience at Least One Treatment-Emergent Adverse Event (TEAE)
Time frame: Baseline up to Day 14
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.
Number of Participants With Markedly Abnormal Values of Vital Signs
Time frame: Baseline up to Day 14
Reported data were numbers of participants who met markedly abnormal criteria of vital signs. Vital signs included body temperature, respiratory rate, blood pressure, and pulse. Vital signs collected were classified as markedly abnormal values if they met the following criteria: systolic blood pressure less than (<) 85 millimeter of mercury (mmHg) or greater than (>) 180 mmHg, diastolic blood pressure <50 mmHg or >110 mmHg, pulse <50 beats per minute (bpm) or >120 bpm, body temperature <35.6 °C or >37.7 °C.
Number of Participants With Markedly Abnormal Values of Clinical Laboratory Test Results
Time frame: Baseline up to Day 14
Reported data were numbers of participants who met markedly abnormal criteria of clinical laboratory test results. Clinical laboratory test results collected were classified as markedly abnormal values if they met the following criteria: red blood cells <0.8×lower limit of normal (LLN) or >1.2×upper limit of normal (ULN), platelets <75×10^3/μL or >600×10^3/μL, white blood cells <0.5×LLN or >1.5×ULN, protein (total) <0.8×LLN or >1.2×ULN, albumin <2.5 g/dL, blood urea nitrogen >30 mg/dL, uric acid >13.0 mg/dL, creatinine >2.0 mg/dL, total cholesterol >300 mg/dL, triglycerides >2.5×ULN, bilirubin (total) >2.0 mg/dL, Sodium <130 mEq/L or >150 mEq/L, Potassium <3.0 mEq/L or >6.0 mEq/L, Chloride <75 mEq/L or >126 mEq/L, Calcium <7.0 mg/dL or >11.5 mg/dL, Phosphorus <1.6 mg/dL or >6.2 mg/dL, alkaline phosphatase >3×ULN, aspartate aminotransferase >3×ULN, alanine aminotransferase >3×ULN, gamma-glutamyl transferase >3×ULN, glucose <50 mg/dL or >350 mg/dL, Magnesium <1.2 mg/dL or >3.0 mg/dL.
Number of Participants With Markedly Abnormal Values of 12-lead Electrocardiogram (ECG)
Time frame: Baseline up to Day 8
Reported data were numbers of participants who met markedly abnormal criteria of 12-lead ECG. A standard 12-lead ECG was performed. The data collected was classified as markedly abnormal values if it met the following criteria: heart rate <50 bpm or >120 bpm, QT interval less than or equal to (<=) 50 msec or greater than or equal to (>=) 460 msec, QTcF interval <=50 msec or either of the following conditions was met: observed value >=500 msec, change from Day 1 Predose >= 30 msec and observed value >=450 msec.
Number of Participants With TEAEs Related to Physical Examinations
Time frame: Baseline up to Day 14
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing TAK-906 in people with Japanese Healthy Adult Male Participants, run by Takeda at 1 site in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants Who Experience at Least One Treatment-Emergent Adverse Event (TEAE) (time frame: Baseline up to Day 14). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2021.
