Remote cognitive assessment and wearable device use in patients with brain tumors receiving metformin

Neuro-Oncology Anywhere: Deploying Mayo Clinic's Remote Cognitive Assessment Battery and Wearable Device Monitoring Platform While Assessing the Impact of Metformin on Cognition and Quality of Life in Patients With History of Cranial Radiation

Phase 2 Interventional Mayo Clinic · NCT06377696

This study is testing if metformin can help improve thinking, activity, and sleep in patients with brain tumors who have had radiation therapy, while also using wearable devices to track their progress.

What this trial studies

This phase II trial evaluates the feasibility of conducting remote cognitive assessments for patients who have undergone cranial radiation therapy. It compares outcomes between those receiving metformin and those who do not, focusing on cognitive function, activity, and sleep data. Participants will be randomized into two groups: one receiving metformin and the other receiving standard care with wearable device monitoring. The study aims to assess patient satisfaction, compliance, and the safety of metformin in this population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a diagnosis of brain tumor requiring cranial radiation treatment.

Not a fit: Patients who have not undergone cranial radiation therapy or those with a poor prognosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve cognitive outcomes and quality of life for patients who have undergone cranial radiation therapy.

How similar studies have performed: Other studies have shown promise in using remote monitoring and metformin for cognitive health, but this specific approach is novel.
