About

Chemotherapy is controversial for soft tissue sarcoma that has not yet metastasized. Surgery and radiation are effective for local control, but there are no highly effective interventions to prevent metastatic spread of soft tissue sarcoma. Immunotherapy has shown promise in other types of cancer. Combining two types of immunotherapy agents with preoperative radiation may help the immune system recognize the sarcoma and stimulate an anti-tumor immune response.

Full description

The main purposes of this study are to evaluate the safety, tolerability, and efficacy of Durvalumab and Tremelimumab in combination with radiation prior to surgical resection of high-risk soft tissue sarcoma in the pelvis and extremities.

Patients will receive the same radiation therapy and surgical care they would receive normally and with no change in timing or duration of each treatment. They will also receive two immunotherapy agents, Durvalumab and Tremelimumab, during radiation prior to surgery, and a single agent, Durvalumab, after surgery.

Written informed consent
Willingness and ability to comply with the protocol for the duration of the study
Histologically confirmed intermediate or high grade adult-type soft tissue sarcoma
Location of tumor is trunk (non-retroperitoneal) or extremities
Tumor at least 5 cm in greatest dimension and deep to fascia, or locally recurrent, or metastatic, or have had prior inadequate resections
Judged as at least marginally resectable
Eastern Cooperative Oncology Group (ECOG) performance status 0-1

Female subjects must be either of non-reproductive potential (i.e., post-menopausal by history: ≥60 years old and no menses for ≥1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.
Females of childbearing potential who are sexually active with a non-sterilized male partner and non-sterilized male subjects who are sexually active with a female partner of childbearing potential must be willing to use 2 methods of effective contraception from time of screening through 180 days after receipt of the final dose of Durvalumab + Tremelimumab combination therapy or 90 days after receipt of the final dose of Durvalumab Monotherapy, whichever is the longer time period.

Exclusion criteria

Primarily bone-based sarcomas that can occur in the soft tissue such as: extra-skeletal Ewing sarcoma, extra-skeletal osteosarcoma, peripheral chordoma, extra-skeletal myxoid chondrosarcoma, and mesenchymal chondrosarcoma

Pediatric-type soft tissue sarcoma, such as rhabdomyosarcoma
Gastrointestinal stromal tumors (GIST)
Retroperitoneal soft tissue sarcoma
Patients with extra-pulmonary metastases aside from lymph node involvement
Surgically unresectable primary lesion
Symptomatic or uncontrolled brain metastases requiring concurrent treatment, inclusive of but not limited to surgery, radiation and/or corticosteroids.
Any previous treatment with an anti-PD-1 (programmed cell death protein-1), anti-PD-L1 (programmed death ligand 1) or anti-CTLA-4 (cytotoxic T-lymphocyte-associated protein 4) therapy, including Durvalumab and Tremelimumab
