Brief Summary:
This is a single-arm, phase II study that will enroll a total of 45 subjects. All subjects will have a confirmed diagnosis of metastatic or unresectable soft tissue sarcoma or bone sarcoma. All subjects must have intact Rb, identified at the time of screening, by immunohistochemistry testing of submitted tumor specimen. Subjects will receive Abemaciclib 200 mg twice daily until progression or discontinuation criteria are met.

Condition or disease Intervention/treatment Phase
Chondrosarcoma Osteosarcoma Soft Tissue Sarcoma Drug: Abemaciclib Phase 2

Detailed Description:

Population to be studied:

Since abemaciclib is already being studied in dedifferentiated liposarcoma patients, patients with this sarcoma subtype will not be enrolled in the current study. This exploratory study will enroll patients with all other types of soft tissue sarcoma, in addition to patients with several bone sarcomas. We are testing the hypothesis that biomarkers of Cyclin D1 - CDK4/6 - Rb pathway activation will identify patients with a rare, heterogeneous cancer who are most likely to benefit from cyclin-dependent kinase 4/6 (CDK4/6) inhibition with abemaciclib.

There will be three cohorts of patients, intended to ensure representation of subjects with rare bone sarcomas - chondrosarcoma and osteosarcoma - that have relatively frequent occurrence of abnormalities in the Cyclin D1 - CDK4/6 - Rb pathway, in addition to soft tissue sarcoma.

Cohort 1 - Conventional chondrosarcoma, 9-12 patients; Cohort 2 - Osteosarcoma, Dedifferentiated chondrosarcoma, 9-12 patients; Cohort 3 - Soft tissue sarcoma (except WD/DD Liposarcoma), 22-26 patients

  9. Subjects must also have had evidence of disease progression by RECIST 1.1 within 6 months of enrollment, or newly diagnosed within the last 6 months (refer to step 1 criteria regarding previous lines of therapy).

  11. A washout period of at least 14 days is required between end of radiotherapy and enrollment.
  12. At least 14 days after surgery, and absence of significant wound healing issues that would pose infection risk.
  13. Subjects with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months are eligible.
