Study Summary

This trial is testing a new drug, NaBen, to see if it's effective in treating residual symptoms of schizophrenia in adults. There are two parts to the trial, and the second part will test the optimal dose of NaBen determined in the first part. The trial will also assess the safety and tolerability of NaBen.

What are the potential side effects?
While specific side effects aren't listed here, participants will be monitored for safety and tolerability of NaBen® in combination with clozapine. This includes watching out for any adverse reactions that may arise during the trial.
