Brief Summary

This phase I/II trial studies pembrolizumab and radiation therapy in treating patients with intermediate or high-grade soft tissue sarcoma. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and 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 pembrolizumab and radiation therapy may work better in treating patients with soft tissue sarcoma.

Detailed Description

OUTLINE:

Patients receive pembrolizumab intravenously (IV) per institutional standard at the Seattle Cancer Care Alliance as an outpatient therapy. Cycles repeat every 3 weeks, up to a maximum of three doses, for 3 months in the absence of disease progression or unacceptable toxicity. Patients also undergo radiation therapy daily for 5-6 weeks beginning on Day 1 of Week 2.

After completion of study treatment, patients are followed up at 30 days after last dose, 90 days after last dose, 30 days after post-operative visit (wound care follow-up), and then every 12 weeks for up to 1 year, then every 6 months up to 5 years.

Conditions

Soft Tissue Sarcoma; Recurrent Soft Tissue Sarcoma

• Be ≥18 years of age on day of signing informed consent documents
• Have measurable disease based on RECIST 1.1
• Have newly diagnosed disease or localized recurrent or oligometastatic lesions that are candidates for radiation

• NOTE: Subjects may not have any prior systemic therapy or radiation for this sarcoma. They may have received systemic therapy and/or radiation for a different cancer
• NOTE: Oligometastatic disease will be defined as 3 or fewer detectable lesions with plans to radiate all detectable disease with conventionally fractionated radiation prior to resection
• Have an intermediate- or high-grade soft tissue sarcoma at the discretion of the reviewing Sarcoma pathologist
• The tumor must be at least 3 cm in maximum dimension for intermediate-grade tumors, or 1.5 cm in maximum dimension for high-grade tumors
• Have plans to undergo neo-adjuvant radiation and surgery with curative intent. A minimum of 45 Gy is necessary, planned to be administered over a minimum of 25 fractions
• Be willing to provide tissue from a newly obtained core incisional or excisional biopsy of a tumor lesion. Archival tissue from a recent clinical or research biopsy (within 90 days prior to Week 1 treatment) may be used in place of a fresh tissue biopsy
• Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale or > 70% on the Karnofsky scale. Evaluation of performance status is to be performed within 7 days prior to the date of enrollment
• Absolute neutrophil count (ANC) >= 1,500/mcL (performed within 28 days of enrollment)
• Platelets >= 100,000/mcL (performed within 28 days of enrollment)
• Hemoglobin >= 9 g/dL or >= 5.6 mmol/L (performed within 28 days of enrollment)

• Criteria must be met without erythropoeiten dependency and without packed red blood cell (pRBC) transfusion within last two weeks
• Serum creatinine =< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) >= 60 mL/min for subject with creatinine levels > 1.5 X institutional ULN (performed within 28 days of enrollment)

• Creatinine clearance should be calculated per institutional standard
• Serum total bilirubin =< 1.5 X ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 ULN (performed within 28 days of enrollment)
• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X ULN (performed within 28 days of enrollment)
• Albumin >= 2.5 mg/dL (performed within 28 days of enrollment)
• International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants (performed within 28 days of enrollment)
• Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (performed within 28 days of enrollment)
• Female subjects of childbearing potential should have a negative serum pregnancy within 72 hours prior to receiving the first dose of study medication
• All individuals of child-bearing potential must be willing to use an adequate method of contraception, from the first dose of the study medication through 120 days after the last dose of study medication

Exclusion Criteria

• Has had prior radiation to affected area
• Has one of the following sarcoma subtypes where neoadjuvant chemotherapy is established as practice at our institution: extra-skeletal Ewing's sarcoma, embryonal rhabdomyosarcoma, alveolar rhabdomyosarcoma

• NOTE: Pleomorphic rhabdomyosarcoma is allowed. Bone sarcomas including osteosarcoma, Ewing's sarcoma and chondrosarcoma are not allowed. Extra-skeletal Osteosarcoma is considered a soft tissue sarcoma and is allowed.

• Has a known history of active TB (Bacillus tuberculosis)
• Hypersensitivity (>= grade 3) to pembrolizumab and/or any of its excipients
• Has a history of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years

• NOTE: The time requirement does not apply to participants who underwent successful definitive resection of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, in situ cervical cancer, or other in-situ cancers
• Has current or a history of any distant metastatic disease (including brain)
