A Phase II Study of LY2880070 and Gemcitabine in People with Ewing Sarcoma or Ewing-Like Sarcoma


Full Title

A Phase II Study of Oral CHK1 Inhibitor LY2880070 in Combination with Low-Dose Gemcitabine in Patients with Relapsed or Refractory Ewing Sarcoma, Ewing-like Sarcoma, and Desmoplastic Small Round Cell Tumor


Researchers are doing this study to find out if the investigational drug LY2880070 combined with the chemotherapy drug gemcitabine is safe and effective for treating people with Ewing sarcoma or Ewing-like sarcoma that has come back or continued to grow despite treatment.

LY2880070 blocks a protein called CHK1, which helps cancer cells repair damaged DNA. By blocking CHK1, LY2880070 may slow or stop the growth of cancer. LY2880070 is taken orally (by mouth) and gemcitabine is given intravenously (by vein).
