Could a schizophrenia drug tame stubborn high blood pressure?
NCT ID NCT07090161
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether iloperidone, a drug already used for schizophrenia, can help lower blood pressure in people whose hypertension is not controlled by their current medications. About 240 adults will receive either iloperidone or a placebo for 4 weeks, and researchers will measure changes in systolic blood pressure. The goal is to see if this drug can be a safe and effective add-on treatment for uncontrolled hypertension.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- iloperidone (Fanapt)
- What this could lead to
- If it works, this could offer a new add-on treatment option for people whose high blood pressure is not controlled by current medications.
- What could go wrong
- This is an early Phase 2 trial with only 240 participants, so results may not apply to everyone. Iloperidone is already approved for other uses, but its safety and effectiveness for hypertension are not yet proven.
Why investors are watching
Vanda Pharmaceuticals is running a Phase 2 trial testing iloperidone, a drug already used for schizophrenia, as a treatment for uncontrolled hypertension. For a small company, this readout matters because it could expand the drug's use into a much larger patient population, changing the company's revenue base beyond its current products.
If it works: If the trial shows iloperidone safely lowers blood pressure in people not controlled by current treatments, Vanda could seek approval for a new indication. That would give the company a second major product and access to a large market of patients with hypertension.
If it fails: Phase 2 trials fail often, and this drug was not originally developed for blood pressure, so the chance of a negative result is real. If the trial fails or is delayed, Vanda loses time and money, and its stock could suffer because the company would remain dependent on its existing drugs.
