Trial Summary

What is the purpose of this trial?

This trial compares two tablets, VHX-896 and Iloperidone, to see if they work the same way in healthy people. Healthy volunteers are used to ensure clear results. The study measures how similarly the body absorbs and processes both tablets. Iloperidone is a medication approved several years ago for the treatment of schizophrenia in adults.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, since the study involves healthy volunteers, it's possible that you may need to pause certain medications. Please consult with the trial coordinators for specific guidance.

What safety data exists for Iloperidone (also known as VHX-896) in humans?

Iloperidone has been studied for the treatment of schizophrenia, and it is considered to have a safety profile similar to other antipsychotic medications. It is known to have moderate affinity for certain brain receptors, which may help reduce side effects common with other antipsychotics.12345

What data supports the effectiveness of the drug Iloperidone, VHX-896?

Iloperidone is shown to be effective in treating schizophrenia, as it improved symptoms in several large clinical trials compared to a placebo. It was also found to have similar effectiveness to other antipsychotic drugs like haloperidol and risperidone, with fewer motor-related side effects.678910

Findings from Research

Iloperidone has been shown to be effective in treating schizophrenia, with multiple dosing groups demonstrating significant improvements over placebo in three randomized, double-blind studies involving 1943 patients.
Iloperidone was associated with a lower risk of motor-related side effects compared to other antipsychotics like risperidone and haloperidol, making it a safer option for patients.
