NCT06324240

Brief Summary

This phase I trial tests the safety, side effects, and best dose of a personalized vaccine (tumor membrane vesicle or TMV vaccine) by itself and in combination with checkpoint inhibitor (pembrolizumab or ipilimumab) in treating patients with triple negative breast cancer. This vaccine is made by taking a piece of patient's triple negative breast cancer to design a vaccine to stimulate the immune system's memory. Patients are treated with the personalized vaccine immunotherapy with or without monoclonal antibodies, such as pembrolizumab and ipilimumab. This approach may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving personalized TMV vaccine with pembrolizumab or ipilimumab may help the immune system attack cancer better and reduce the risk of this breast cancer coming back or growing.

Outcome Measures

Primary Outcomes (2)

  • Incidence of adverse events (Phase Ia)

    Safety and tolerability will be assessed by adverse events (AE), vital signs, physical exam findings, clinical laboratory safety assessments and incidence of treatment-emergent AE. AE events will be assessed according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 and will be evaluated by grade and organ class.

    Up to 2 years

  • Dose limiting toxicity (Phase Ia)

    Defined by the occurrence of any grade 3 or greater AEs that are at least possibly related to protocol therapy administration, except for grade 3 injection site reactions that are adequately controlled by medical treatment (e.g. steroid administration) and except for inadequately treated nausea, vomiting, diarrhea, or fever.

    Up to week 5

Secondary Outcomes (8)

  • Immune stimulating activity- T cell activity

    Up to 12 weeks after final vaccination

  • Immune stimulating activity- Plasma cytokine/chemokines

    Up to 12 weeks after final vaccination

  • Optimal biologic dose

    Up to week 5

  • Recommended phase 2 dose (Phase Ib)

    Up to week 5

  • Disease control rate

    Up to 2 years

  • +3 more secondary outcomes

Other Outcomes (3)

  • PD-L1 expression

    Up to 2 years

  • TIL density

    Up to 2 years

  • BRCA 1/2 mutation status

    Up to 2 years

Study Arms (3)

Phase Ia (TMV vaccine)

EXPERIMENTAL

Patients receive TMV vaccine ID at weeks 1, 3, and 5 in the absence of disease progression or unacceptable toxicity.

EXPERIMENTAL

Patients receive TMV vaccine ID at weeks 1, 3, and 5 in the absence of disease progression or unacceptable toxicity. Patients also receive pembrolizumab IV on day 1. Treatment with pembrolizumab repeats every 21 days for 6-9 cycles in the absence of disease progression or unacceptable toxicity.

Biological: PembrolizumabBiological: Vaccine Therapy

Phase Ib Arm B ( TMV vaccine, ipilimumab)

EXPERIMENTAL

Patients receive TMV vaccine ID at weeks 1, 3, and 5 in the absence of disease progression or unacceptable toxicity. Patients also receive ipilimumab IV on day 1. Treatment with ipilimumab repeats every 21 days for 4 cycles in the absence of disease progression or unacceptable toxicity.
