Key inclusion & exclusion criteria
|
Inclusion criteria: 1. Be willing and able to provide written informed consent/assent for the trial. The subject may also provide consent/assent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research.
2. Be = 18 years of age on day of signing informed consent (or acceptable age according to local regulations, whichever is older).
3. Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale within 10 days prior to the first dose of trial treatment.
4. Have histologically or cytologically confirmed diagnosis of locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma.
5. Be HER2/neu negative and PD-L1 positive.
6. Have measurable disease as defined by RECIST 1.1 as determined by investigator assessment. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
7. Have provided tumor tissue sample deemed adequate for PD-L1 biomarker analysis.
a. Notification of eligibility must be received prior to randomization.
b. Additional samples may be required if adequate tissue is not provided.
8. Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of study medication. If
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
9. Female subjects of childbearing potential must be willing to use an adequate method of contraception, for the course of the study through 120 days after the last dose of study medication.
Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
10. Male subjects of childbearing potential must agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.
Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
11. Demonstrate adequate organ function. All screening labs should be performed within 10 days of treatment initiation.
Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 600 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 150
Exclusion criteria: 1. Has squamous cell or undifferentiated gastric cancer.
2. Has had previous therapy for locally advanced, unresectable or metastatic gastric/GEJ cancer. Subjects may have received prior neoadjuvant or adjuvant therapy as long as it was completed at least 6 months prior to randomization.
3. Has had major surgery, open biopsy or significant traumatic injury within 28 days prior to randomization, or anticipation of the need for major surgery during the course of study treatment.
4. Has had radiotherapy within 14 days of randomization. Subjects who received radiotherapy >14 days prior to randomization must have completely recovered from any radiotherapy related AEs/toxicities.

This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability.
7. Has an active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
8. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial drug.
9. Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis.
10. Has an active infection requiring systemic therapy.
11. Has a history or current evidence of any condition (e.g. known deficiency of the enzyme dihydropyrimidine dehydrogenase [DPD]), therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject’s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
12. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
13. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 180 days after the last dose of trial treatment.
14. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
15. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
16. Has known active Hepatitis

Primary Outcome(s)
|
Main Objective: In subjects with advanced gastric or GEJ adenocarcinoma treated with pembrolizumab monotherapy or a combination of pembrolizumab with chemotherapy versus chemotherapy alone, as first-line treatment in subjects with PD-L1 expression. Objective 1: Evaluate Progression Free Survival (PFS) per RECIST 1.1 as assessed by blinded central radiologists’ review in subjects with PD-L1 Combined Positive Score (CPS) = 1. Objective 2: Evaluate overall survival (OS).
|
Primary end point(s): Efficacy Endpoints This trial (MK3475-062) will use a dual endpoint of OS and PFS. PFS is an acceptable scientific endpoint for a randomized Phase III trial to demonstrate superiority of a new antineoplastic therapy. RECIST 1.1 will be used to determine the dates of progression as this methodology is accepted by regulatory authorities. Because the treatment assignment is unblinded for pembrolizumab monotherapy, images will be read by central radiologists blinded to treatment assignment to minimize bias in the response. RECIST 1.1 as assessed by the central vendor will be used as the primary PFS efficacy endpoint. Standard RECIST 1.1 will be used by the local site for treatment decisions until verification of PD by the central imaging vendor. Following verification of PD by central vendor, treatment decision may be made by the adaptation of RECIST 1.1, termed immune-related RECIST (irRECIST )
|
Timepoint(s) of evaluation of this end point: Response will be assessed throughout the study. The first protocol defined response assessment is scheduled for Week 6, with additional assessments following at 6 week intervals.
|
Secondary Objective: (1) Objective: Evaluate Overall Response Rate (ORR), and Duration of Response (DOR), per RECIST 1.1 as assessed by central radiologists in subjects with PD-L1 CPS = 1. (2) Objective: Evaluate Progression Free Survival (PFS) per RECIST 1.1 as assessed by blinded central radiologists' review in subjects treated with Pembrolizumab. (3) Objective: Evaluate the safety and tolerability profile. (4) Objective: Evaluate changes in health-related quality-of-life assessments from baseline using the EORTC QLQ-C30 and the EORTC QLQ-STO22

Secondary end point(s): Safety Endpoints
The safety objective of this trial is to characterize the safety and tolerability of pembrolizumab monotherapy and in combination therapy in subjects with gastric or GEJ adenocarcinoma. The safety analysis will be based on subjects who experienced toxicities as defined by CTCAE criteria. Safety will be assessed by quantifying the toxicities and grades experienced by subjects who have received study treatments, including serious adverse events (SAEs) and events of clinical interest (ECIs).
Safety will be assessed by reported adverse experiences using CTCAE, Version 4.0. The attribution to drug, time-of-onset, duration of the event, its resolution, and any concomitant medications administered will be recorded. AEs will be analyzed including but not limited to all AEs, SAEs, fatal AEs, and laboratory changes.
Furthermore, specific immune-related adverse events (irAEs) will be collected and designated as immune-related ECIs.
|
Timepoint(s) of evaluation of this end point: Safety will be assessed at all study visits conducted either in person or by phone.
