简要总结
This phase II trial tests whether atezolizumab in combination with selinexor works to shrink tumors in patients with alveolar soft part sarcoma and whether the study drugs are better than the usual approach in treating this type of cancer. The usual approach is defined as care most people get for alveolar soft part sarcoma if they are not part of a clinical study, which includes treatment with radiation, kinase inhibitor drugs, immunotherapy drugs, or chemotherapy drugs. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Selinexor is in a class of medications called selective inhibitors of nuclear export (SINE). It works by blocking a protein called CRM1, which may help keep cancer cells from growing and may kill them. Giving atezolizumab in combination with selinexor may help shrink tumors and stabilize the cancer in patients with alveolar soft part sarcoma.
详细描述
PRIMARY OBJECTIVE:
I. Determine the overall response rate (by Response Evaluation Criteria in Solid Tumors [RECIST] version [v]1.1) for selinexor in combination with atezolizumab in patients with alveolar soft part sarcoma (ASPS) whose disease progressed and who have received prior immune checkpoint inhibitor (ICI) therapy.
SECONDARY OBJECTIVE:
I. Assess the number of activated CD8+ T cells infiltrating the tumor before and after atezolizumab + selinexor combination treatment, and correlate treatment-induced changes with clinical response.

On-study documentation will include a physician's rationale that supports evidence of clinical disease progression (i.e., increasing tumor pain)

- •Treatment with any other agent administered for the treatment of the patient's cancer, within five half-lives or 3 weeks prior to cycle 1, day 1, whichever is shorter
- •History of malignancy other than ASPS prior to screening, with the exception of malignancies with a negligible risk of metastasis or death (e.g., 5-year overall survival [OS] rate > 90%), such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or stage I uterine cancer
- •Treatment with systemic immunostimulatory agents (including, but not limited to, interferon and interleukin 2 [IL-2]) within 4 weeks or 5 half-lives of the drug (whichever is longer) prior to initiation of study treatment
- •Treatment with systemic immunosuppressive medications (including, but not limited to, prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor [anti-TNF] agents) within 2 weeks prior to cycle 1, day 1 or anticipation of need for systemic immunosuppressive medication during study treatment, with the following exceptions:

- •No metastases to brain stem, midbrain, pons, medulla, or cerebellum
- •No history of intracranial hemorrhage or spinal cord hemorrhage
- •No ongoing requirement for dexamethasone for CNS; patients on a stable dose of anticonvulsants are permitted.
- •No neurosurgical resection or brain biopsy within 28 days prior to cycle 1, day 1
- •Patients with asymptomatic treated CNS metastases may be enrolled, provided all the criteria listed above are met as well as the following:
- •Radiographic demonstration of improvement upon the completion of CNS-directed therapy and no evidence of interim progression between the completion of CNS-directed therapy and radiographic screening for the current study
- •No stereotactic radiation or whole-brain radiation within 28 days prior to cycle 1, day 1
- •Screening CNS radiographic study >= 4 weeks from completion of radiotherapy and >= 2 weeks from discontinuation of corticosteroids
- •History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric antibodies, fusion proteins, or Chinese hamster ovary cell products or to any component of the atezolizumab formulation
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to atezolizumab or selinexor
- •Patients with uncontrolled intercurrent illness, prior malignancy, any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications
- •Patients who are pregnant or breastfeeding, or are expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 5 months after the last dose of atezolizumab or 3 months after the last dose of selinexor, whichever is longer. A woman of childbearing potential (WOCBP) who has a positive urine pregnancy test (e.g., within 8 days) prior to treatment will be excluded from the study. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Women of childbearing potential must have a negative urine pregnancy test result within 8 days prior to initiation of study treatment. Pregnant women are excluded from this study because atezolizumab is a monoclonal antibody agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with atezolizumab, breastfeeding should be discontinued if the mother is treated with atezolizumab. These potential risks may also apply to selinexor. Due to the potential risks, WOCBPs and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and 5 months after completion of atezolizumab administration or 3 months after completion of selinexor administration, whichever is longer. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately

Patients receiving prophylactic antibiotics (e.g., for prevention of a urinary tract infection or chronic obstructive pulmonary disease) are eligible
- •Major surgical procedure within 28 days prior to cycle 1, day 1
