CAR-T Cells for HIV Infection

Recruiting now · Phase 1/Phase 2

Conditions studied: HIV Infections

In brief

This is a limited-center, open-label dose escalating phase I/IIa study of autologous T cells expressing LVgp120duoCAR molecules in people with HIV infection. It will follow a 3+3 design. Dose escalation decisions will be made when a minimum of three participants have completed the safety-evaluation period (45 days) at a given dose level. Cohort 1 will undergo infusion of a single low-dose regimen of LVgp120duoCAR-T cells. Cohort 2 will undergo non-ablative conditioning with cyclophosphamide, followed by infusion of a single low-dose regimen of LVgp120duoCAR-T cells. Cohort 3 will undergo non-ablative conditioning with cyclophosphamide, followed infusion of a single high-dose regimen of LVgp120duoCAR-T cells. Following administration of the experimental therapy, HIV medications will be paused for participants in each group during an analytic treatment interruption.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female, age ≥ 18 and ≤ 65 years
• HIV-1 infection
• On continuous antiretroviral therapy for at least 12 months without any interruptions of greater than 14 consecutive days, and on a stable regimen that does not include a non-nucleoside reverse transcriptase inhibitor (NNRTI) for at least 4 weeks or any long-acting ART drug that may be active in the participant after ART interruption for up to one year, without plans to modify ART during the study period
• Screening plasma HIV RNA levels below the limit of quantification on all available determinations in past 12 months (isolated single values ≥ 40 but < 200 copies/mL will be allowed if they were preceded and followed by undetectable viral load determinations)
• CD4+ T cell count nadir > 300 cells/mm3
• Screening CD4+ T-cell count ≥ 500 cells/mm3
• Available ART treatment history and the capacity to construct an effective antiretroviral treatment regimen
• Willing to pause ART as part of the study

You may not qualify if…

• Pregnant, breastfeeding, or unwilling to practice birth control during participation in the study
• ART regimen that includes a long-acting anti-HIV drug and/or NNRTI that may be active in the participant for up to one year after ART interruption
• ART regimen that includes protease inhibitor(s) and/or AZT. These drugs may increase the toxicity of cyclophosphamide.
• Any history of an HIV-associated malignancy, including Kaposi's sarcoma and any type of lymphoma, or virus-associated cancers
• History of or current active hepatitis B (HBV) infection defined as positive HBV surface antigen test. A positive anti-HBc regardless of HBsAg status.
• Active hepatitis C (HCV) infection
• Active or latent tuberculosis infection
• Chronic liver disease
• Active and poorly controlled atherosclerotic cardiovascular disease
• Unwillingness to abstain from sex or use barrier protection for any sexual activity during the treatment interruption.
