Not an actual patient

In a key 144-week clinical trial, treatment based on an EVOTAZ regimen was comparable to an atazanavir/ritonavir-based regimen.

*Viral load less than 50 copies/mL.

The clinical trial

This 144-week clinical trial looked at 692 adults living with HIV, who:

  • Had a weakened immune system (average CD4+ cell count of 352 cells/mm3)
  • Had a normal level of kidney function (average creatinine clearance over 70 mL/min)
Patients were split into two study groups, each of which took different meds
Key measurements
  • At 144-weeks, viral load and T cell count were measured in both trial groups.
