Using doxycycline to slow emphysema in people with HIV

1/2 Doxycycline for Emphysema in People Living with HIV: The DEPTH Trial

NIH-funded research Weill Medical Coll of Cornell Univ · NIH-10911918

The DEPTH trial is looking at whether the antibiotic doxycycline can help slow down emphysema in people with well-controlled HIV who are current or former smokers, and you'll either get doxycycline or a placebo for 72 weeks to see how it affects your lung function.

What this research studies

The DEPTH trial investigates the use of doxycycline, an antibiotic, to slow the progression of emphysema in individuals living with HIV. This phase II trial will involve participants who are current or former smokers and have well-controlled HIV. Participants will be randomly assigned to receive either doxycycline or a placebo for 72 weeks, with the primary goal of measuring changes in lung function. The study aims to target specific biological markers associated with emphysema progression in this population.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults living with HIV who have been diagnosed with emphysema and are current or former smokers.

Not a fit: Patients who do not have emphysema or those with uncontrolled HIV may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a new therapeutic option to slow down emphysema progression in people living with HIV.

How similar studies have performed: Previous studies have shown the feasibility of targeting matrix metalloproteinases in HIV-positive individuals with emphysema, indicating potential for success in this approach.
