Current Primary Outcome Measures (submitted: September 6, 2023)

Progression Free Survival [ Time Frame: From start of treatment until date of progression or death, whichever occurs first, up to 1 year follow-up ]

To evaluate the progression free survival (PFS) of subjects with recurrent platinum-resistant ovarian, fallopian tube or primary peritoneal cancer receiving gemcitabine in combination with AZD1775 compared to subjects receiving gemcitabine in combination with placebo. Progression is defined, using the Response Evaluation Criteria In Solid Tumors (RECIST v1.1) guideline, as at least a 20% increase in the sum of the diameters of target lesions or the appearance of one or more new lesions.

• Original Primary Outcome Measures (submitted: March 28, 2014): PFS evaluated using RECIST version 1.1 [ Time Frame: Time from start of treatment to time to progression or death, whichever occurs first, assessed up to 1 year ]

Current Secondary Outcome Measures (submitted: September 6, 2023)

• Objective Response [ Time Frame: From start of treatment, every 6-8 weeks, until time of progression or death, whichever occurs first, up to 1 year follow-up ]
  To evaluate the objective response per Response Evaluation Criteria in Solid Tumors (RECIST v1.1) of patients receiving gemcitabine combined with AZD1775 compared to patients receiving gemcitabine in combination with placebo. RECIST v1.1 criteria used for evaluation of target lesions: Complete Response (CR), disappearance of all target lesions; Partial Response (PR), at least a 30% decrease in the sum of the diameters of target lesions; Progressive Disease (PD), at least a 20% increase in the sum of the diameters of target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. The Best Overall Response is the best response recorded from the start of the treatment until disease progression/recurrence .
• Response According to CA125 Criteria [ Time Frame: From start of treatment, every 4 weeks, until time of progression or death, whichever occurs first, up to 1 year follow-up ]
  To evaluate the GCIG CA125 response rate of patients receiving gemcitabine combined with AZD1775 compared to patients receiving gemcitabine in combination with placebo. A response according to CA-125 has occurred if there is at least a 50% reduction in CA-125 levels from a pre-treatment sample. The response must be confirmed and maintained for at least 28 days.
• Overall Survival [ Time Frame: From start of study treatment, every 12 weeks, until death, up to 22 months follow-up ]
  To evaluate the overall survival of patients receiving gemcitabine combined with AZD1775 compared to patients receiving gemcitabine in combination with placebo.

• p53 Protein Expression [ Time Frame: Baseline ]
  To evaluate p53 protein expression by immunohistochemistry as potential predictive factors of benefit (defined as response or PFS prolongation) to AZD1775 and gemcitabine treatment.

• GCIG CA125 response rate [ Time Frame: Up to 1 year ]
• Overall survival [ Time Frame: Up to 1 year ]
  Survival estimates will be computed using the Kaplan-Meier method.
• Incidence of grade 3 or 4 serious adverse events graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: Up to 1 year ]
• TP53 mutations (presence and type of mutation) by Sanger sequencing [ Time Frame: Baseline ]

Descriptive Information

• Brief Title: Gemcitabine Hydrochloride With or Without WEE1 Inhibitor MK-1775 in Treating Patients With Recurrent Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
• Official Title: A Randomized Placebo-Controlled Phase II Trial Comparing Gemcitabine Monotherapy to Gemcitabine in Combination With AZD 1775 (MK 1775) in Women With Recurrent, Platinum Resistant Epithelial Ovarian, Primary Peritoneal, or Fallopian Tube Cancers
• Brief Summary: This randomized phase II clinical trial studies how well gemcitabine hydrochloride and WEE1 inhibitor MK-1775 work compared to gemcitabine hydrochloride alone in treating patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back after a period of time. Gemcitabine hydrochloride may prevent tumor cells from multiplying by damaging their deoxyribonucleic acid (DNA, molecules that contain instructions for the proper development and functioning of cells), which in turn stops the tumor from growing. The protein WEE1 may help to repair the damaged tumor cells, so the tumor continues to grow. WEE1 inhibitor MK-1775 may block the WEE1 protein activity and may increase the effectiveness of gemcitabine hydrochloride by preventing the WEE1 protein from repairing damaged tumor cells without causing harm to normal cells. It is not yet known whether gemcitabine hydrochloride with or without WEE1 inhibitor MK-1775 may be an effective treatment for recurrent ovarian, primary peritoneal, or fallopian tube cancer.
