Brief Summary:
The primary objectives are to assess the antiviral activity, clinical safety and tolerability parameters of albuvirtide/3BNC117 combination therapy in reducing HIV-1 viral load during the 1-week induction period treatment period.

Condition or disease Intervention/treatment Phase
HIV/AIDS Drug: Albuvirtide Drug: 3BNC117 Antibody Phase 2

Detailed Description:
This is a Phase 2, multi-center study to evaluate the efficacy, safety, and tolerability of ABT/3BNC117 combination in conjunction with an existing failing antiretroviral therapy (ART) for 1 week, and then with optimized background regimen (OBR) for 24 weeks, respectively. A total of 20 eligible subjects who demonstrate evidence of HIV-1 replication despite ongoing antiretroviral therapy with documented genotypic and/or phenotypic resistance to multiple classes of HIV drugs (3 classes or more) will be enrolled. Patients must have been treated with HAART for at least 6 months and be failing or have recently failed (i.e., in the last 8 weeks) therapy to determine baseline viral load.

Criteria

Inclusion Criteria:

  1. Males and females, age ≥ 18 years;
  2. HIV-1 seropositive with documented HIV-1 infection by official, signed, written history (e.g. Laboratory report)
  3. Receiving a combination antiretroviral therapy (cART) (failing regimen) for at least 8 weeks before Screening and are willing to continue on the failing regimen during the Screening Phase and up to Day 14 of the Treatment Phase, OR have failed in the past 8 weeks of Screening, are off therapy and are willing to stay off therapy until Day 14 of the Treatment Phase;
  4. Plasma HIV-1 RNA ≥ 1000 copies/mL at the Screening Visit and documented detectable viral load (HIV-1 RNA >200 copies/ml) within the last 3 months prior to the Screening Visit;
  5. Highly treatment-experienced HIV-infected patients with genotypic and/or phenotypic resistance to at least one ARV drug for each of three or more drug classes of antiretroviral medications at the Screening Visit and have difficulty in constructing a viable suppressive regimen;
  6. Have full viral sensitivity/susceptibility to at least one approved antiretroviral agent, other than ABT and 3BNC117, as determined by genotypic and/or phenotypic ARV drug resistance tests at screening, and such agent can be used as a component of OBR;
