What this research studies

If you have MAC lung disease, researchers are screening existing and new antibiotics in laboratory models to find combinations that kill the bacteria faster and work well together. They use pharmacokinetic and pharmacodynamic data to choose drug doses and identify synergy or antagonism between drugs. Promising combinations from the lab work will be translated toward clinical regimens with the goal of much shorter courses than the current year-plus treatments. The team aims to prioritize safe, effective pairs or triplets of drugs that could move into patient testing.

Who could benefit from this research

Good fit: People diagnosed with pulmonary Mycobacterium avium complex (MAC) infection, especially those starting therapy or with persistent positive sputum cultures, would be the ideal candidates.

Not a fit: People without MAC or with other non-NTM lung conditions, and those whose infections are resistant to the specific drugs studied, are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, this work could produce shorter treatment courses that raise cure rates and reduce side effects for people with MAC lung disease.

How similar studies have performed: While combination antibiotic strategies have improved outcomes in other infections, short-course, PK/PD-guided combination regimens for MAC are largely unproven and this approach is relatively novel.
