Brief Summary:
The purpose of this study is to determine whether ribociclib are effective and safe in the treatment of progressive well/dedifferentiated liposarcoma (WDL/DDL).

Condition or disease Intervention/treatment Phase
Liposarcoma Soft Tissue Sarcoma Drug: ribociclib Phase 2

Detailed Description:

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 quantitative analysis of CDK4 gene copy number using FISH, immunostaining for p16 and cyclin D1 all using formalin fixed paraffin embedded (FFPE) tissue sections. In addition tumor DNA, extracted from FFPE tissue (after choosing optimal area by a Pathologist), will be submitted to a next generation sequencing analysis ("ion ampliseq" cancer panel v2©) for a later exploratory analysis.

Other Name: LEE011

Primary Outcome Measures :
  1. Response to therapy as evaluated by RECIST 1.1 and Choi [ Time Frame: 36 months (24 months accrual period and 12 month follow up period) ]

Secondary Outcome Measures :
  1. Median PFS and PFS assessed at 12 weeks (PFS will be computed from the date of start of treatment to the first documented date of progression or the date of death, due to any cause assessed by investigator. [ Time Frame: 12 weeks ]
  2. Overall survival (OS) will be computed from the date of start of treatment to the date of death, due to any cause. Patients alive or lost for follow-up at the time of the analysis will be censored at the date of last follow-up. [ Time Frame: 36 months (24 months accrual period and 12 month follow up period) ]
  3. Evaluate the time from first documented response to disease progression [ Time Frame: 36 months (24 months accrual period and 12 month follow up period) ]
