A Phase II Clinical Trial Evaluating the Efficacy and Safety of Sintilimab for Advanced Rare Cancers (SiARa Cancer Study) - Undifferentiated Pleomorphic Sarcoma (SiARa-UPS)

2020-1046

This phase II trial investigates the effects of sintilimab in treating patients with undifferentiated pleomorphic sarcoma that has spread to nearby tissue or lymph nodes (locally advanced), spread to other places in the body (metastatic), come back (recurrent), or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as sintilimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Exception: Patients with known Gilbert disease: serum bilirubin level =\< 3 x ULN * Urine protein \< 2+ from random sample or \< 1 g from 24-hour urine collection, and creatinine clearance rate (Ccr) \>= 60 mL/min by Cockcroft-Gault formula * Adequate coagulation function, defined as international normalized ratio (INR) =\< 1.5 or prothrombin time (PT) =\< 1.5 x ULN; if the subject is receiving anticoagulant therapy, the results of coagulation tests need to be within the acceptable range for anticoagulants * Expected survival \>= 12 weeks * Subject (female subjects of childbearing age or male subjects whose partners are of childbearing age) must take effective contraceptive measures during the entire course of the trial and until 180 days after the last dose * Signed the informed consent form (ICF) and be able to comply with the scheduled follow-up visits and related procedures required in the protocol Exclusion Criteria: * Received treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any other antibody or drug that specifically targets T-cell co-stimulation or immune checkpoint pathways * Enrolled in another interventional clinical study, unless only involved in an observational study (non-interventional) or in the follow-up phase of an interventional study * Received palliative therapy for local lesion within 2 weeks prior to the first dose * Received systemic treatment with anti-cancer indications or immunomodulators (including thymosins, interferons, and interleukins) within 2 weeks prior to the first dose of study treatment * Received systemic immunosuppressants within 2 weeks prior to first dose, excluding local use of glucocorticoids administered by nasal, inhaled, or other routes, and systemic glucocorticoids at physiological doses (no more than 10 mg/day of prednisone or equivalents), or glucocorticoids to prevent allergies to contrast media * Received a live attenuated vaccine within 4 weeks prior to the first dose of study treatment or be scheduled to receive live attenuated vaccine during the study period. * Note: Seasonal inactivated influenza virus vaccines within 4 weeks prior to the first dose of study treatment are permitted, but attenuated influenza vaccines are not * Received major surgery (craniotomy, thoracotomy, or laparotomy) within 4 weeks prior to the first dose of study treatment or is scheduled to receive major surgery during the course of the trial * Any toxicity (excluding alopecia, events that are not clinically significant, or asymptomatic laboratory abnormalities) due to prior anti-tumor therapy that has not yet resolved to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0 grade 0 or 1 prior to the first dose of study treatment * Known symptomatic central nervous system (CNS) metastasis or carcinomatous meningitis. Subjects with brain metastases who have received prior treatment can be enrolled if the disease is stable (no imaging evidence of progressive disease (PD) for at least 4 weeks prior to the first dose of study treatment), there is no evidence of new brain metastases or progression of the existing metastatic lesion(s) upon repeated imaging, and corticosteroids have not been required for at least 14 days prior to the first dose of study treatment. Patients with carcinomatous meningitis are ineligible, regardless of whether the disease is clinically stable or not * Subjects with bone metastases at risk of paraplegia * Known active autoimmune disease requiring treatment or previous disease history within 2 years (subjects with vitiligo, psoriasis, alopecia, or Graves' disease not requiring systemic treatment, hypothyroidism only requiring thyroid replacement, or type I diabetes only requiring insulin can be enrolled) * Known history of primary immunodeficiency diseases * Known active pulmonary tuberculosis * Known history of allogeneic organ transplantation or allogeneic hematopoietic stem cell transplantation * Human immunodeficiency virus (HIV)-infected subjects (positive anti-HIV antibody) * Active or poorly controlled serious infections * Symptomatic congestive heart failure (New York Heart Association \[NYHA\] class II-IV) or symptomatic or poorly controlled arrhythmia * Uncontrolled hypertension (systolic blood pressure \>= 160 mmHg or diastolic blood pressure \>= 100 mmHg) despite of standard treatment * Any arterial thromboembolic event within 6 months prior to enrollment, including myocardial infarction, unstable angina, cerebrovascular accident, or transient cerebral ischemic attack * Significant malnutrition, such as those requiring continuous parenteral nutrition \>= 7 days; excluding those having received intravenous treatment for malnutrition for more than 4 weeks before the first dose of study treatment * History of clinically significant deep venous thrombosis, pulmonary embolism, or other serious thromboembolic events within 3 months prior to enrollment (implantable port or catheter-related thrombosis or incidental PE detected on scan without symptoms or superficial venous thrombosis are not considered as "serious" thromboembolisms) * Uncontrolled metabolic disorders, non-malignant organ or systemic diseases, or cancer-related secondary diseases that may lead to higher medical risks and/or survival evaluation uncertainties * Hepatic encephalopathy, hepatorenal syndrome, or cirrhosis with Child-Pugh class B or C * Bowel obstruction or history of the following diseases: inflammatory bowel disease, extensive bowel resection (partial colectomy or extensive small intestine resection accompanied with chronic diarrhea), Crohn's disease, or ulcerative colitis * Known acute or chronic active hepatitis B (positive hepatitis B surface antigen \[HBsAg\] and hepatitis B virus \[HBV\] DNA viral load \>= 104 copies/mL or \> 2000 IU/mL), or acute or chronic active hepatitis C (hepatitis C virus \[HCV\] ribonucleic acid \[RNA\] \> 103 copies/mL), or simultaneously positive for HBsAg and HCV antibody * History of gastrointestinal (GI) perforation and/or fistula within 6 months prior to the enrollment, excluding gastrostomy or enterostomy * Interstitial lung disease requiring corticosteroids * History of other primary malignant tumors, excluding: * Malignant tumors that achieved a complete response (CR) at least 2 years prior to enrollment and expected to require no treatment during the trial * Adequately treated nonmelanoma skin cancer or lentigo maligna with no sign of disease recurrence * Adequately treated carcinoma in situ with no sign of disease recurrence * Prostate, chronic lymphocytic leukemia (CLL) or other cancers where the indolent nature of tumor allows for and patient is cancer under active surveillance * Pregnant or breastfeeding female subjects * Acute or chronic diseases, psychiatric disorders, or laboratory abnormalities that may lead to the following consequences: increased investigational drug-related risks, interference with interpretation of trial results or considered ineligible for participating in the trial by the investigators
