DRIVE-FORWARD trial

PIFELTRO® DRIVE-FORWARD trial*

Pifeltro Drive Forward Trial

Entry criteria:1

  • Adults ≥18 years of age
  • Plasma HIV-1 RNA ≥1000 copies/mL (at screening)
  • Naïve to antiretroviral therapy
  • No documented or known resistance to any of the study drugs
  • Calculated creatinine clearance ≥50 mL/min
  • Alkaline phosphatase concentrations ≤3X ULN
  • Aminotransferase concentration ≤5X ULN

PIFELTRO® demonstrated a non-inferior proportion of patients achieving HIV RNA <50 copies/mL at 48 weeks vs. DRV/r, each in combination with FTC/TDF or ABC/3TC and at Week 96, efficacy in the PIFELTRO® group was higher vs. the DRV/r group (using the FDA snapshot approach, secondary endpoint) supporting the non-inferiority previously established at Week 482,*

* DRIVE-FORWARD: Randomized, multicenter, double-blind, active-controlled trial. Adult ART-naïve patients (n=766) were randomized to PIFELTRO® or DRV/r orally, each in combination with FTC/TDF or ABC/3TC once daily, for 48 weeks. Patients also received placebos that matched the other treatment. The prespecified non-inferiority margin at Week 48 was -10%.

NRTI=nucleoside reverse-transcriptase inhibitor; FTC=emtricitabine; TDF=tenofovir disoproxil fumarate; ABC= abacavir; 3TC= lamivudine; DRV/r=darunavir boosted with ritonavir; ULN=upper limit of normal; CI=confidence interval; ART=antiretroviral therapy
