A combination regimen containing high-dose rifampin (also known as rifampicin) was associated with faster tuberculosis bacteria culture conversion in people with drug-sensitive TB, but moxifloxacin and the experimental drug SQ109 showed no benefit compared to standard therapy, according to results from a study presented at the recent 2015 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle.

The promising experimental tuberculosis (TB) drug delamanid does not interact with the widely used antiretrovirals tenofovir (Viread) and lopinavir/ritonavir (Kaletra) in ways likely to cause clinical problems, researchers reported at the XIX International AIDS Conference (AIDS 2012) last month in Washington, DC.
