Genetic-guided psychotropic medication choices for adults in Manitoba

Pharmacogenomics-Supported Psychotropic Prescribing Trial (PGx-SUPPORT): A Pilot Implementation Study in Manitoba

Not applicable Interventional University of Manitoba · NCT06929533

This project will test whether using a patient's genetics to guide psychotropic medication choices helps adults in Manitoba who are starting or changing psychiatric medicines.

What this trial studies

This interventional project offers pharmacogenetic (PGx) testing using saliva samples to adults seeking mental health care in Manitoba and tracks whether test results influence prescribing. Feasibility will be measured across acceptability (patient and clinician satisfaction), practicality (turnaround time), implementation (clinicians' use of results), and demand (referrals and intent to use). Secondary outcomes include changes in global functioning and symptom severity using measures such as CGI, BPRS, PHQ-9, and GAD-7. The work is delivered through Shared Health facilities and the University of Manitoba with local clinician referrals.

Who should consider this trial

Good fit: Adults aged 18 or older in Manitoba who are starting, changing, adjusting, or augmenting psychotropic medications and who are referred by a treating clinician, can provide a saliva sample, and have a personal health identification number.

Not a fit: Patients who already have pharmacogenetic results, who are unwilling to provide a saliva sample, who lack a personal health identification number, or who have had liver or bone marrow transplants are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, PGx-guided prescribing could speed finding the right medication, reduce adverse reactions, and improve symptom control.

How similar studies have performed: Some prior pharmacogenetic-guided prescribing studies have shown modest improvements in medication selection and fewer adverse reactions, but results have been mixed and local feasibility in Manitoba has not been tested.
