EVOTAZ and Drug Resistance

EVOTAZ can help defend against drug resistance
Not an actual patient

Keeping up the right drug levels in your body is important for lowering your viral load to undetectable and reducing the chance of drug resistance.

No patients developed resistance to the MEDICINES in EVOTAZ in a key clinical trial

After 144 weeks, this clinical trial found that a treatment based on an EVOTAZ regimen was comparable to an atazanavir/ritonavir-based regimen.
