Detailed Summary

This randomized phase II trial studies how well ATR kinase inhibitor M6620 (M6620) and gemcitabine hydrochloride work compared to standard treatment with gemcitabine hydrochloride alone in treating patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back after a period of improvement (recurrent). ATR kinase inhibitor M6620 may stop the growth of tumor cells by blocking an enzyme needed for cell growth, and may also help gemcitabine hydrochloride work better. Gemcitabine hydrochloride is a drug used in chemotherapy that works to stop the growth of tumor cells by blocking cells from growing and repairing themselves, causing them to die. It is not yet known whether adding ATR kinase inhibitor M6620 to standard treatment with gemcitabine hydrochloride is more effective than gemcitabine hydrochloride alone in treating patients with ovarian, primary peritoneal, or fallopian tube cancer.

Arms & Interventions

Arm I (gemcitabine hydrochloride)active_comparator

Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression may crossover to Arm II.

Drug: GemcitabineDrug: Gemcitabine Hydrochloride
Arm II (gemcitabine, ATR kinase inhibitor M6620)experimental

Patients receive gemcitabine hydrochloride as in Arm I and ATR kinase inhibitor M6620 IV over 60-90 minutes on days 2 and 9. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
