Using metformin to improve treatment for tuberculosis in people with HIV

Trial of Metformin for TB/HIV Host-directed Therapy

NIH-funded research Univ of Massachusetts Med Sch Worcester · NIH-10870157

This study is looking at whether metformin, a diabetes medication, can help people with both tuberculosis and HIV get better faster when combined with their usual TB treatment, and it’s for those who might struggle with standard therapies.

What this research studies

This research investigates the use of metformin, a medication commonly used for diabetes, as a potential treatment to enhance the effectiveness of tuberculosis (TB) therapy in patients who are also living with HIV. The study aims to stimulate the body's natural defenses to help clear TB more quickly and effectively, particularly in individuals who face challenges with traditional multi-drug regimens. Participants will be randomly assigned to receive either metformin or a placebo alongside standard TB treatment, with a focus on monitoring safety and tolerability. The goal is to determine if metformin can improve health outcomes for this vulnerable population.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who are co-infected with tuberculosis and HIV.

Not a fit: Patients who do not have tuberculosis or HIV may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to faster and more effective TB treatment for patients living with HIV, potentially reducing mortality and improving recovery.

How similar studies have performed: Previous studies have shown promising results for metformin in enhancing immune responses in TB patients, suggesting potential for success in this approach.
