This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Researchers are testing how the body absorbs TAK-935, an experimental drug, when given as a 300 mg tablet compared with a 300 mg oral solution. They also want to know whether taking the tablet with food changes how much of the drug reaches the bloodstream. The study enrolls a small group of healthy adults who receive single doses and provide blood samples. The goal is to understand the drug's behavior in the body, not to treat any condition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
TAK-935, an experimental drug given as a tablet or oral solution
What this could lead to
If the tablet form delivers the drug reliably, it could support later trials that test TAK-935 as a treatment for neurological or psychiatric conditions.
What could go wrong
This is a tiny Phase 1 study in healthy volunteers, so it cannot show whether the drug works for any disease. It only measures blood levels and short-term safety.
