简要总结
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.
详细描述
PRIMARY OBJECTIVES:
I. To determine the safety and tolerability of TMV vaccine when delivered intradermally as monotherapy in patients with early stage TNBC for Phase 1a. II. To determine immune stimulating activity and an optimal biological dose (OBD) of TMV vaccine when delivered intradermally as monotherapy for Phase 1a.
III. To determine the safety and tolerability of TMV vaccine under OBD when delivered intradermally in combination with PD-1-inhibitor pembrolizumab or CTLA-4 inhibitor ipilimumab in patients with metastatic TNBC (mTNBC) and patients with early stage TNBC for Phase 1b.
SECONDARY OBJECTIVES:
I. To determine immune stimulating activity of TMV vaccine when delivered intradermally as in combination with checkpoint inhibitor therapy in adult patients with TNBC (TNBC) for Phase 1b.

- •Weight of tumor tissue for production of vaccine must be at least 1 gram. In metastatic patients, preferentially, invasive tumor in breast or lymph node tissue will be retrieved by excisional biopsy to ensure sufficient yield. In metastatic patients who undergo initiation of first-line standard of care systemic therapy off study (i.e. pembrolizumab and chemotherapy in a PD-L1 positive patient), then ideally collection of tumor tissue will occur prior to treatment initiation of standard of care therapy to maximize cellularity. Metastatic patients who have undergone mastectomy during curative treatment initially or have no invasive disease in the breast, chest wall, or accessible regional lymph nodes, will be evaluated for image-guided core biopsies of liver metastasis or video-assisted thorascopic wedge resection of lung metastasis
- •In patients with early stage TNBC undergoing upfront surgery, the tumor tissue will be retrieved during lumpectomy/mastectomy. In early stage patients who are identified as high risk of having residual disease after neoadjuvant chemotherapy or undergo upfront resection, tissue will be retrieved during planned lumpectomy or mastectomy
