Study of Chemotherapy With Pembrolizumab (MK-3475) Followed by Maintenance With Olaparib (MK-7339) for the First-Line Treatment of Women With BRCA Non-mutated Advanced Epithelial Ovarian Cancer (EOC) (MK-7339-001/KEYLYNK-001/ENGOT-ov43)

NCT03740165

Description:

The purpose of this study is to assess the efficacy and safety of treatment with carboplatin/paclitaxel PLUS pembrolizumab (MK-3475) and maintenance olaparib (MK-7339) in women with epithelial ovarian cancer (EOC), fallopian tube cancer, or primary peritoneal cancer. The primary study hypotheses are that the combination of pembrolizumab plus carboplatin/paclitaxel followed by continued pembrolizumab and maintenance olaparib is superior to carboplatin/paclitaxel alone with respect to Progression Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) and/or Overall Survival (OS), and that the combination of pembrolizumab plus carboplatin/paclitaxel followed by continued pembrolizumab is superior to carboplatin/paclitaxel alone with respect to PFS per RECIST 1.1 and/or OS.

Detailed Description

      Following a lead-in period during which all participants receive a single 3-week cycle of
      carboplatin/paclitaxel, participants will be randomly assigned in to one of three treatment
      arms:

        -  Pembrolizumab+Olaparib,

        -  Pembrolizumab+Placebo for Olaparib, or

        -  Placebo for Pembrolizumab+Placebo for Olaparib.

      At Investigator's discretion and prior to participant randomization, one of the following
      carboplatin/paclitaxel regimens is to be selected:

        1. up to 5 cycles of carboplatin Area Under the Curve (AUC)5 or AUC6 AND paclitaxel 175
           mg/m^2 on Day 1 of each 3-week cycle

        2. up to 5 cycles of carboplatin AUC5 or AUC6 on Day 1 of each 3-week cycle AND paclitaxel
           80 mg/m^2 on Days 1, 8 and 15 of each 3-week cycle; or

        3. up to 5 cycles of carboplatin AUC2 or AUC2.7 AND paclitaxel 60 mg/m^2 on Days 1, 8 and
           15 of each 3-week cycle.

Primary Outcome Measures

Measure:Progression-Free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by the Investigator
Time Frame:Up to approximately 6 years
Safety Issue:
Description:PFS is defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 based on Investigator assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more lesions and the unequivocal progression of non-target lesions is also considered PD. The PFS per RECIST 1.1 as assessed by the Investigator will be presented.

Secondary Outcome Measures

Measure:PFS Per RECIST 1.1 As Assessed by Blinded Independent Central Review
Time Frame:Up to approximately 6 years
Safety Issue:
Description:PFS is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on blinded independent central review assessment or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more lesions and the unequivocal progression of non-target lesions is also considered PD. The PFS per RECIST 1.1 as assessed by blinded independent central review will be presented.
Measure:PFS After Next-line Treatment (PFS2) Following Discontinuation of Study Treatment As Assessed by the Investigator
Time Frame:Up to approximately 78 months
Safety Issue:
Description:PFS2 is defined as the time from randomization until PD on next-line treatment or death due to any cause, whichever occurs first. The PFS2 per Investigator assessment will be presented.
Measure:Number of Participants Who Experience an Adverse Event (AE)
Time Frame:Up to approximately 73 months
Safety Issue:
Description:An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE will be presented.

Time Frame:Up to approximately 6 years
Safety Issue:
Description:The number of participants who discontinue study treatment due to an AE will be presented.

Safety Issue:
Description:Participants are asked to answer 2 questions from the EORTC QLQ-C30 about their GHS: "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" Responses are based on a 7-point scale (1=Very poor; 7=Excellent), with a higher score indicating a better global health status. The change from baseline in GHS/QoL score of participants will be presented.
