Brief Summary:
The aim of this protocol is to evaluate the effects of romidepsin plus 3BNC117 or romidepsin alone on delaying or preventing viral rebound in ART-treated HIV-1-infected individuals during an analytical interruption of ART.

Condition or disease Intervention/treatment Phase
Human Immunodeficiency Virus (HIV) Drug: 3BNC117 Drug: Romidepsin Phase 2

Detailed Description:

This is a randomized interventional phase 2a trial of 3BNC117 and romidepsin in human immunodeficiency (HIV-1) infected patients on ART, conducted as a multi-center study at the Department of Infectious Diseases, Aarhus University Hospital, Denmark, the Rockefeller University Hospital, USA, and the University Hospital of Cologne, Germany.

Participants will be randomized 1:1 in a non-blinded fashion to receive one of two regimens:

A) Two treatment cycles each consisting of one 3BNC117 infusion (30mg/kg) + three romidepsin infusions (5mg/m2); or

B) Two treatment cycles each consisting of three romidepsin infusions (5mg/m2).

ART will be discontinued 16 weeks after the start of the second treatment cycle (analytical treatment interruption, ATI) and subjects will be monitored weekly for safety and viral rebound. The targeted enrollment is 30 subjects (15 per arm).

Leukapheresis will be performed before and after the two treatment cycles to guarantee sufficient material to investigate changes in the reservoir after the interventions.

The following criteria will require resumption of ART:

  • CD4+ T cell-count <350 cells/mm³ (confirmed by repeat measurement)
  • 2 consecutive plasma HIV-1 RNA measurements ≥ 200 copies/mL or above their setpoint viremia (if documented)
  • Subject request
  • Continued ART interruption will, in the opinion of the investigator or study advisers, pose an unacceptable risk to the subject.

If HIV-1 RNA remains undetectable at week 36, subjects will be offered to continue off ART with close monitoring, in conjunction with the subject's primary medical provider, as long as HIV-1 viral rebound does not occur. ART resumption will follow same criteria as detailed above. All subjects will be followed for a total of 48 weeks from enrollment.

Primary Outcome Measures :
  1. Days to Viral Rebound During Analytical Treatment Interruption (ATI) [ Time Frame: Week 24 to Week 36 ]
    Viral rebound is defined as HIV-1 RNA ≥ 200 copies/mL on 2 consecutive measurements during ATI. If viral rebound occurs, the date of the first measurement of HIV-1 RNA ≥ 200 copies/mL will be defined as "date of viral rebound

Secondary Outcome Measures :
  1. Number of of Adverse Events (AE), Serious Adverse Events (SAE), and Serious Unexpected Serious Adverse Reactions (SUSAR). [ Time Frame: 48 weeks ]
    The occurrence of adverse events was assessed during each follow up visit. Adverse events of grades 1 or higher were reported.

  2. Change in the Size of the Proviral HIV-1 Reservoir [ Time Frame: baseline and week 24 ]
    Determined by total HIV-1 DNA and episomal HIV-1 DNA (2-LTR) in circulating total CD4+ T cells at baseline and prior to the ATI period (week 24).

  3. Plasma HIV-1 RNA [ Time Frame: 48 weeks ]
    As measured by a routine clinical assay (Cobas Taqman; detection limit 20 copies/mL), a transcription mediated amplification (TMA)-based assay (detection limit 12 copies/ml) and/or a single copy assay (detection limit 1-2 copies/mL)

Other Outcome Measures:
  1. HIV-1 Transcriptional Activity as Determined by Unspliced HIV-1 RNA (CA usHIV-1 RNA) in Circulating Total CD4+ T Cells. [ Time Frame: baseline and week 24 ]
    The median fold-change in cell-associated unspliced HIV-1 RNA concentrations after romidepsin administration across all infusions
