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.

Detailed description

PRIMARY OBJECTIVES: I. To evaluate the progression free survival (PFS) of subjects with recurrent platinum-resistant ovarian, fallopian tube or primary peritoneal cancer receiving gemcitabine (gemcitabine hydrochloride) in combination with AZD 1775 (MK-1775 \[WEE1 inhibitor MK-1775\]) compared to subjects receiving gemcitabine in combination with placebo. SECONDARY OBJECTIVES: I. To evaluate the objective response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 of patients receiving gemcitabine combined with AZD 1775 (MK-1775) compared to patients receiving gemcitabine in combination with placebo. II. To evaluate the Gynecologic Cancer Intergroup (GCIG) cancer antigen (CA)125 response rate of patients receiving gemcitabine combined with AZD 1775 (MK-1775) compared to patients receiving gemcitabine in combination with placebo. III. To evaluate the overall survival of patients (max 1-year \[yr\] follow-up) receiving gemcitabine combined with AZD 1775 (MK-1775) compared to patients receiving gemcitabine in combination with placebo. IV. To evaluate the safety and tolerability of the combination of gemcitabine combined with AZD 1775 (MK-1775) in patients with recurrent, platinum-resistant ovarian, fallopian tube or primary peritoneal cancer. V. To evaluate tumor protein p53 (TP53) mutations (presence of mutation and type of mutation) as potential predictive factors of benefit (defined as response or progression-free survival \[PFS\] prolongation) to AZD 1775 (MK-1775) and gemcitabine treatment. VI. To evaluate p53 protein expression by immunohistochemistry as potential predictive factors of benefit (defined as response or PFS prolongation) to AZD 1775 (MK-1775) and gemcitabine treatment. TERTIARY OBJECTIVES: I. To evaluate patient reported outcomes using Patient-Reported Outcomes (PRO)-Common Terminology Criteria for Adverse Events (CTCAE). II. To evaluate the concordance of TP53 mutations in the tumor specimen and TP53 mutations determined by tagged-amplicon deep sequencing (Tam-Seq) in circulating tumor DNA. III. To correlate the levels circulating DNA TP53 mutations by Tam-Seq with response. IV. Validation of phosphorylated-cyclin-dependent cycle 2 (pCDC2) and gamma-H2A histone family, member X (H2AX) in skin and tumor tissue as a pharmacodynamic marker of therapy. V. To correlate changes in pCDC2 and gamma-H2AX with survival outcomes and response rate. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive WEE1 inhibitor MK-1775 orally (PO) on days 1, 2, 8, 9, 15, and 16 and gemcitabine hydrochloride intravenously (IV) over 30 minutes on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive placebo PO on days 1, 2, 8, 9, 15, and 16 and gemcitabine hydrochloride as patients in Arm I. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6-8 weeks (after the 30-37 day safety visit) for up to 1 year.

Recruitment details

Between Oct. 16, 2014 and Jan. 16, 2018, 124 women were enrolled, of whom 99 had high-grade serous ovarian cancer and were randomly assigned to AZD1775 plus gemcitabine (65 \[66%\]) or placebo plus gemcitabine (34 \[34%\]). 25 women with non-high-grade serous ovarian cancer were enrolled in the exploratory cohort.

Pre-assignment details

After randomization, five patients with high-grade serous ovarian cancer were found to be ineligible (four in the experimental group and one in the control group) and did not receive treatment.

Objective Response

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 .

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

p53 Protein Expression

To evaluate p53 protein expression by immunohistochemistry as potential predictive factors of benefit (defined as response or PFS prolongation) to AZD1775 and gemcitabine treatment. Evaluating p53 expression in patients with high-grade serous ovarian cancer and in patients with high-grade serous ovarian cancer with TP53 mutations.

Response According to CA125 Criteria

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.

Patient Reported Outcomes

Will be assessed using Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE). Each symptomatic AE is assessed with respect to 1 to 3 of the following attributes: frequency (F), severity (S) and/or interference (I) with usual or daily activities, and a recall period of 'the past 7 days'. PRO-CTCAE responses are scored from 0 to 4 with scores of 3 and 4 corresponding to high frequency, severity and/or interference. Results show the number of patients in each arm reporting high scores (3-4) for symptomatic AEs occurring in \>30% of patients
