Durvalumab, Tremelimumab, and Radiation Therapy in Treating Participants with High Risk Soft-Tissue Sarcoma

Trial Status: Active

This phase I / II trial studies the side effects of durvalumab, tremelimumab, and radiation therapy and to see how well they work in treating participants with high risk soft-tissue sarcoma. Monoclonal antibodies, such as durvalumab and tremelimumab, may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving durvalumab, tremelimumab, and radiation therapy may work better at treating high risk soft-tissue sarcoma.

PRIMARY OBJECTIVES:

(1) Objective: Phase I component:To evaluate the safety and tolerability of neoadjuvant durvalumab/tremelimumab and radiation therapy in patients with high-risk soft-tissue sarcoma (STS).

(2) Objective: Phase II component: To evaluate the proportion of patients achieving an excellent response (>= 90% necrosis/treatment response) on histopathologic examination of the surgical specimen.

SECONDARY OBJECTIVES:

(3) Objective: To evaluate the clinical outcomes of distant relapse, progression of disease, and disease-specific survival with neoadjuvant durvalumab/tremelimumab and radiation therapy (RT) followed by surgical resection.

(4) Objective: To evaluate the histopathologic effect of neoadjuvant durvalumab/tremelimumab and radiation therapy on the primary tumor.

(5) Objective: To evaluate the effect of neoadjuvant durvalumab/tremelimumab and radiation therapy on the primary tumor using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria and the immune-related response criteria (irRC).

(6) Objective: To evaluate whether neoadjuvant durvalumab/tremelimumab and radiation therapy produces tumor-specific immune responses within the tumor, the infiltrative margins and surrounding reactive zone, and in the peripheral blood, and whether the strength of these responses correlate with the extent of tumor microsatellite instability and mutagenic burden.

EXPLORATORY OBJECTIVES:

(7) Objective: To evaluate the effect of neoadjuvant durvalumab/tremelimumab and radiation therapy on the primary tumor using Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) criteria.

OUTLINE:

Radiation treatment will be given over 5-7 weeks. Tremelimumab is given as a 60 minute infusion followed by an hour break. Then Durvalumab is given, as a 60 minute infusion into a vein (IV). You will receive this combination infusion three times (each time separated by 4 weeks) prior to surgery. One time will be before radiation, one time during the 5-7 weeks of radiation, and one time after radiation. After surgery, you will receive Durvalumab only. Those patients with no detectable tumor will receive 4 doses (separated by 4 weeks each time). Those with detectable tumor will receive 9 doses (separated by 4 weeks each time). If your cancer is getting worse, if you need different treatment, or if you have bad side effects, your immunotherapy treatment may be stopped in favor of different treatment. Researchers will follow you for up to two years after you stop study treatment (your doctor will follow you for longer periods of time for routine monitoring of the cancer) and after you stop taking the immunotherapy drugs, the study staff will continue to contact you to see how you are doing.

This is an open-label study, which means that everyone in the study will get radiation and Durvalumab/Tremelimumab followed by surgical tumor removal and then Durvalumab after surgery.
