Patient case: 38-year-old male with Liposarcoma. Genetic variant: CDK4 Amplification. Other conditions: GERD.

Clinical trial: Study of Abemaciclib in Dedifferentiated Liposarcoma

Summary: The purpose of this study is to test any good and bad effects of the study drug called Abemaciclib. Abemaciclib could shrink your cancer but it could also cause side effects. Researchers hope to learn if the study drug will delay the growth of the cancer or shrink the cancer by at least one quarter compared to its present size. Abemaciclib is not FDA approved and has not been tested in liposarcoma, but it has shrunk tumors in patients with breast cancer, lymphoma, and lung cancer.


Eligibility: Inclusion Criteria:
  -  A diagnosis of dedifferentiated liposarcoma confirmed at MSKCC.
  -  Metastatic and/or locally advanced or locally recurrent disease that is not surgically resectable.

Patients receiving BCNU or mitomycin C must have received their last dose of such therapy at least 6 weeks prior to initiation of therapy.
  -  Patients with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months are eligible.
  -  Age ≥ 18 years.
  -  ECOG performance status 0 or 1
