About this study

Official title: A Phase I Trial Using Third-Generation CAR-T-cell Therapy in Individuals With HIV-1 Infection

To evaluate the safety of autologous CAR-T-cell therapy in individuals lived with HIV-1 infection, CAR T cells are infused after ex vivo expansion and transduction with lentiviral vectors encoding a broadly neutralizing HIV-1 scFv antibody.

Read the detailed description

This study is a prospective, single-center, single-arm, open-label and phase I clinical trial. Subjects with CD4+T cell counts greater than 350/μl and viral loads of <50 copies/ml over 1 year by antiviral treatment are enrolled. T cells are stimulated with CD3 and CD28, transduced with lentiviral vectors encoding a broadly neutralizing HIV-1 scFv antibody and expanded for approximately 2 weeks. Then, patients are infused with CAR T cells at a dosage of 1×10^5 CAR-T cells/kg body weight. If this dose is well tolerated, dosing will be increased to 5×10^5 CAR T cells/kg body weight. After infusion, adverse events, and HIV-1 latent reservoir size and CAR levels in peripheral blood will be monitored to assess the safety of CAR-T-cell treatment, potential therapeutic efficacy and kinetics of CAR T cells.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CAR-T cellsBiological

    Also called HIV-1 specific chimeric antigen receptor T cells

    The presence of latent infected cells remains a key barrier to HIV-1 functional cure. Current approach to reducing the latent HIV reservoir is to reactivate virus-containing cells to make them be detected and eliminated by host defense. Endogenous cytotoxic T-lymphocytes (CTL) may not be adequate because of cellular exhaustion and immune escape of virus. We have designed a kind of CAR-T cell based on CTL engineered to express a scFv of a broadly neutralizing anti-HIV antibody. According to our preclinical studies, CAR-T cells strongly eradicated HIV-1-infected target cells making them a particularly suitable candidate to reach a functional HIV cure. In this clinical trial, we mainly intend to evaluate the safety of CAR-T-Cell therapy on HIV patients whose plasma HIV has been successfully suppressed after antiviral therapy.

Study groupRoleWhat they receive
CAR-T-cell therapyExperimentalFour patients with plasma HIV RNA <50 copies/ml and CD4+T cell count more than 350 cells/μl receiving at least one-year antiviral treatment are injected intravenously with 1×10^5 CAR-T cells/kg body weight. If the dosage of 1×10^5 CAR-T cells/kg body weight is well tolerated, 5×10^5 CAR-T cells/kg body weight will be infused for another 4 subjects who meet the inclusion and exclusion criteria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 28 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jinfang Zhao, MD (010-93332866, zhaojinfang13@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluation the safety of CAR-T-cell treatment (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04863066, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2021.
