简要总结
The purpose of this study is to determine whether ribociclib are effective and safe in the treatment of progressive well/dedifferentiated liposarcoma (WDL/DDL).
详细描述
The expected duration of this study is 36 months (24 months accrual period and 12 month follow up period). Enrollment into the screening or treatment phase of the study will be stopped when the actual subject numbers have been achieved.
This single arm single institution, open label, prospective, phase II trial will evaluate the efficacy and safety of oral 600mg/daily in 28 day cycles of ribociclib in advanced well-differentiated liposarcoma (WDL) and de-differentiated liposarcoma (DDL) patients. Number of patients in the study will reflect the reconciliation between statistical requirements and incidence.
Treatment will continue until disease progression, development of unacceptable toxicity, noncompliance or withdrawal of consent by the patient or investigator decision.
All screening requirements must be completed within 28 days of the visit (except for CDK4/6 amplification and pRb, p16 and cyclin D staining status which may be completed in advance). Patients will be examined on cycle 1 day-1 and every 2 weeks, including complete blood count (CBC) and chemistry, for the first 8 weeks of treatment, and thereafter every month until disease progression. CT/MRI imaging (contrast) will be performed every 8 weeks for response evaluation. Clinical benefit as well as individual categories of response (complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) will be determined using Response Evaluation Criteria in Solid Tumors 1.1 (RECIST). Response duration endpoints, including PFS, PFS at 12 weeks and OS will be assessed using the Kaplan-Meier method. Toxicity (AEs) will be recorded using the NCI- Common Toxicity Criteria for Adverse Effects v 4.03 (NCI-CTCAE). Screening procedures will include medical history, physical examination, blood test, baseline CT/MRI imaging and formalin-fixed tissue submission for FoundationOne mutational analysis.
