NCT05432635

Brief Summary

This phase I trial studies the safety and side effects of cytomegalovirus (CMV) specific CD19-chimeric antigen receptor (CAR) T-cells along with the CMV-modified vaccinia Ankara (MVA) triplex vaccine following a stem cell transplant in treating patients with high grade B-cell non-Hodgkin lymphoma. CAR T-cells are a type of treatment in which a patient's T-cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T-cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T-cells are grown in the laboratory and given to the patient by infusion. Vaccines such as CMV-MVA triplex are made from gene-modified viruses and may help the body build an effective immune response to kill cancer cells. Giving CMV-specific CD19-CAR T-cells plus the CMV-MVA triplex vaccine following a stem cell transplant may help prevent the cancer from coming back.

Outcome Measures

Primary Outcomes (1)

  • Incidence of adverse events

    Will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0 from data obtained at each clinical assessment. Will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.

    Up to 15 years

Secondary Outcomes (5)

  • Achievement of proposed 10Ă—10^6 cytomegalovirus (CMV)-specific CD19-chimeric antigen receptor (CAR) T cells per product and meeting product release requirements for enrolled participants

    Up to 56 days

  • Short- and long-term CMV-specific CD19-CAR T cell expansion and persistence

    Up to 15 years

  • Clinically significant CMV reactivation

    Up to 15 years

  • Progression-free survival (PFS)

    From the start of treatment to the date of death, disease relapse, or last follow-up whichever occurs first, assessed up to 15 years

  • Overall survival (OS)

    From start of protocol therapy to death, or last follow-up, whichever comes first, assessed up to 15 years

Study Arms (1)

Treatment (CMV-specific CD19-CAR T cells, triplex vaccine)

EXPERIMENTAL

CONDITIONING REGIMEN: Patients receive standard conditioning regimen (typically carmustine, etoposide, cytarabine, melphalan) beginning approximately on day -9 in the absence of disease progression or unacceptable toxicity. TRANSPLANTATION: Patients undergo autoHSCT on day -2. CAR T-CELLS AND VACCINATION: Patients receive CMV-specific CD19-CAR T cells IV on day 0 and CMV-MVA triplex vaccine IM on days 28 and 56 in the absence of disease progression or unacceptable toxicity.
