| HIV HIV/AIDS HIV-1 Infection | Drug: Pegylated Interferon alpha 2b (peg-IFN-α2b) Drug: 3BNC117 + 10-1074 | Phase 1 |
The proposed study will evaluate the safety, tolerability and innate immune mechanisms activation following administration of the combination of Pegylated Interferon alpha 2b (peg-IFN-α2b) with two broadly neutralizing antibodies (3BNC117 and 10-1074) in the setting of well controlled HIV infection with antiretroviral treatment and a monitored analytical treatment interruption. This proposal builds on previous experience using interferon alpha, 3BNC117 and 10-1074 alone in separate clinical trials that included a closely monitored analytical treatment interruption. The hypothesis is that the joint administration of peg-IFN-α2b with 3BNC117 and 10-1074 will be more effective than either intervention separately in suppressing HIV viremia during 8 weeks of analytical treatment interruption (Step 4) and reducing integrated HIV DNA in blood and tissue when measured during an analytical treatment interruption in participants with well-controlled HIV infection. A review of the conceptual framework for the strategy to be tested includes:
- Why peg-IFN-α2? The therapeutic effects of peg-IFN-α2 yield two essential outcomes that are the fundamental objectives of HIV curative strategies: control viral replication in the absence of ART and reduce the levels of integrated HIV DNA in CD4+ T-cells. To date, peg-IFN-α is the only intervention that has been shown to maintain viral suppression to levels <50 copies/mL in the absence of ART in chronic infection. Preliminary data supports that correlates of anti-HIV reductions are centered on activation of NK responses.
- Why bNAbs + peg-IFN-α2b? The addition of bNAbs may act independently to control virus replication or decrease fitness thereby increasing the potential for a larger antiviral effect after IFN by enhance NK-mediated clearance via a reduced viral levels and the complementarity of bNAbs in enhancing mechanisms of antibody-mediated cytotoxicity against infected cells by binding to virus emerging from or viral proteins expressed on activated latent cells.
- Why combined bNAbs? In vivo, multiple bNAbs targeting different epitopes provide better neutralization and antigen recognition than single bNAbs, which suggests that adoptive transfer of multiple bNAbs may lead to superior viral control. Although bNAbs may have neutralization effects that are of greater clinical impact than ADCC, it is possible that antigen targeting through multiple bNAbs may also enhance NK-mediated cytotoxicity more than a single bNAb. The administration of broadly neutralizing antibodies alone in the setting of an analytical treatment interruption delays the return of viremia in a fraction of the participants.
- Why test an ATI of immunotherapy? To date, peg-IFN-α2 administered prior to an ATI or ART and subsequently maintained throughout the ATI period has maintained viral suppression. An effective curative strategy requires that all interventions be discontinued.
| Study Type : | Interventional (Clinical Trial) |
| Actual Enrollment : | 15 participants |
| Allocation: | Non-Randomized |
| Intervention Model: | Parallel Assignment |
| Intervention Model Description: | The study will evaluate the impact of the combination of 3BNC117 and 10-1074 with or without antiretroviral therapy in virological rebound during an ATI and effects on the HIV reservoir. This will be a pilot phase I study to evaluate the safety, tolerability, pharmacokinetics (PK), and antiviral activity of a combination of Pegylated Interferon alpha 2b with the two broadly neutralizing antibodies (3BNC117 and 10-1074) in 14 (all recruited first) individuals or the combination the broadly neutralizing antibodies alone in 7 (only 1 was able to be recruited due to COVID delays and drug availability) HIV-1 infected individuals, undergoing a brief analytical treatment interruption (ATI). |
