About this study

Official title: A Phase 1 Bioavailability and Food Effect Study to Compare Tablet Versus Solution Formulation and to Assess the Effect of Food on the Bioavailability of a Single TAK-935 Dose in Healthy Subjects

The purpose of this study is to assess the relative bioavailability (BA) of 300 milligram (mg) TAK-935 tablets compared to 300 mg of TAK-935 solution and to determine the effect of food on the BA of TAK-935 300 mg tablets in healthy adult participants.

Read the detailed description

The drug being tested in this study is called TAK-935. The study will look at the relative BA of TAK-935 300 mg tablets compared to a TAK-935 300 mg oral solution and will assess the effect of food on the BA of TAK-935 300 mg tablets in healthy adult participants.

The study will enroll approximately 9 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the 3 treatment sequences:

  • TAK-935 (300 mg Tablets Fed + 300 mg Tablets Fasted + 300 mg Solution Fasted)
  • TAK-935 (300 mg Tablets Fasted + 300 mg Solution Fasted + 300 mg Tablets Fed)
  • TAK-935 (300 mg Solution Fasted + 300 mg Tablets Fed + 300 mg Tablets Fasted)

Administration of each dose will be separated by a washout period of at least 3 days. Participants will be asked to take single dose of TAK-935 tablet or oral solution on Day 1 of each Intervention Period.

This single center trial will be conducted in the United States. The overall time to participate in this study is 39 days. Participants will remain confined to the clinic from Day 1 of Intervention Period 1 to Day 3 of Intervention Period 3 and will be contacted by telephone 30 days after last dose of TAK-935 for a follow-up assessment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cmax: Maximum Observed Plasma Concentration for TAK-935

    Measured: Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose

  2. AUCt: Area Under the Plasma Concentration-time Curve From Time 0 to the Time of the Last Quantifiable Concentration for TAK-935

    Measured: Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose

  3. AUC∞: Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for TAK-935

    Measured: Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose

Secondary outcomes (4)
  1. Percentage of Participants Who Experience at Least One Treatment Emergent Adverse Event (TEAE)

    Measured: Baseline up to 30 days after last dose of study drug (Day 39)

  2. Percentage of Participants Who Meet the Markedly Abnormal Criteria for Safety Laboratory Tests at Least Once Post Dose

    Measured: Baseline up to Day 11

  3. Percentage of Participants Who Meet the Markedly Abnormal Criteria for Vital Sign Measurements at Least Once Post Dose.

    Measured: Baseline up to Day 11

  4. Percentage of Participants Who Meet the Markedly Abnormal Criteria for Safety Electrocardiogram (ECG) Parameters at Least Once Post Dose

    Measured: Baseline up to Day 11

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TAK-935 Tablets and TAK-935 Oral Solution in people with Healthy Volunteers, run by Takeda at 1 site in United States.

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 1 inclusion and 8 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 14 Sep 2026. 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 United States. 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. 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 19 Sep 2018). 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?

Cmax: Maximum Observed Plasma Concentration for TAK-935 (time frame: Day 1 pre-dose and at multiple time points (up to 48 hours) post-dose). The study lists 3 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 14 Sep 2026.
