ClinConnect Summary

This clinical trial is studying how a new treatment, OLZ/SAM, affects weight gain in young people with schizophrenia or bipolar I disorder compared to a standard medication called olanzapine. The researchers want to see if the new treatment leads to less weight gain, which is measured using something called the BMI Z-score—a number that helps to understand if a person’s weight is healthy for their age and height.

To participate in this study, young people aged 10 to 17 years with bipolar I disorder or 13 to 17 years with schizophrenia may be eligible if they have been diagnosed by a healthcare professional and have some support from family or guardians. They should not have serious other mental health issues and should not be at risk of harming themselves or others. Participants can expect to receive either the new treatment or olanzapine and will be monitored closely throughout the study. This trial is currently looking for participants, and it aims to help improve treatment options for these conditions while managing potential weight gain.
