Study of Pembrolizumab (MK-3475) vs Placebo for Participants With Non-small Cell Lung Cancer After Resection With or Without Standard Adjuvant Therapy (MK-3475-091/KEYNOTE-091)
- Conditions
- Non-small Cell Lung Cancer
- Interventions
- Biological: PembrolizumabOther: Placebo
- Registration Number
- NCT02504372
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
In this study, participants with Stage IB/II-IIIA non-small cell lung cancer (NSCLC) who have undergone surgical resection (lobectomy or pneumonectomy) with or without adjuvant chemotherapy will be treated with pembrolizumab or placebo. The primary study hypothesis is that pembrolizumab will provide improved disease-free survival (DFS) versus placebo.

- No prior or planned neo-adjuvant or adjuvant radiotherapy and/or neo-adjuvant chemotherapy for the current malignancy is allowed
- Evidence of disease at clinical examination and/or baseline radiological assessment as documented by contrast enhanced chest/upper abdomen CT scan, brain CT/MRI and clinical examination
- More than 4 cycles of adjuvant therapy
- Prior treatment with anti-programmed cell death (anti-PD)-1, anti-PD ligand-1/2, anti-CD137, or cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) modulators or any other immune-modulating agents
- Live vaccine within 30 days prior to the first infusion of study treatment

- Chronic use of immunosuppressive agents and/or systemic corticosteroids or any use in the last 3 days prior to the first infusion of study treatment
- History of interstitial lung disease or (non-infectious) pneumonitis that required oral or IV steroids (other than COPD exacerbation) or current pneumonitis
- Active autoimmune disease that has required systemic treatment in past 2 years
- History of a hematologic or primary solid tumor malignancy, unless in remission for at least 5 years with the exception of pT1-2 prostatic cancer Gleason score < 6, superficial bladder cancer, non melanomatous skin cancer or carcinoma in situ of the cervix
- Previous allogeneic tissue/solid organ transplant
- Active infection requiring therapy
- Surgery- or chemotherapy-related toxicity (non-hematological) not resolved to Grade 1 with the exception of alopecia, fatigue, neuropathy and lack of appetite /nausea
- Pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last infusion of study treatment
- Participant will not be eligible if the participant is or has an immediate family member (e.g., spouse, parent/legal guardian, sibling or child) who is investigational site or Sponsor staff directly involved with this trial, unless prospective site Review Board approval is given allowing exception to this criterion for a specific participant

Group Intervention Description Pembrolizumab Pembrolizumab Participants receive pembrolizumab 200 mg, intravenously (IV), every 3 weeks, for one year (expected maximum 18 doses). Placebo Placebo Participants receive placebo, IV, every 3 weeks, for one year (expected maximum 18 doses).
- Primary Outcome Measures
Name Time Method Disease-Free Survival (DFS) Up to approximately 84 months DFS was defined as the time from randomization to either the date of disease recurrence or death (whatever the cause) as assessed by the investigator. Recurrence of disease was defined as local regional recurrence, a distant (metastatic) recurrence, or a second primary cancer. Occurrence of a second extra-pulmonary malignancy was considered to be an event.
DFS in Programmed Death Ligand-1 (PDL-1) Strong Positive Participants With Tumor Proportion Score (TPS) ≥50% Up to approximately 84 months DFS in PDL-1 strong positive participants with TPS ≥50% was defined as the time from randomization to either the date of disease recurrence or death (whatever the cause) as assessed by the investigator. Recurrence of disease was defined as local regional recurrence, a distant (metastatic) recurrence, or a second primary cancer. Occurrence of a second extra-pulmonary malignancy was considered to be an event.
- Secondary Outcome Measures
Name Time Method Overall Survival (OS) Up to approximately 132 months OS was defined as the time from randomization to the date of death.
Lung Cancer Specific Survival (LCSS) Up to approximately 132 months LCSS was defined as the time from randomization to the date of death (due to lung cancer specifically).
DFS in PDL-1 Strong Positive Participants With TPS ≥1% Up to approximately 84 months DFS in PDL-1 strong positive participants with TPS ≥1% was defined as the time from randomization to either the date of disease recurrence or death (whatever the cause) as assessed by the investigator. Recurrence of disease was defined as local regional recurrence, a distant (metastatic) recurrence, or a second primary cancer. Occurrence of a second extra-pulmonary malignancy was considered to be an event.
OS in PDL-1 Strong Positive Participants With TPS ≥50% Up to approximately 132 months OS in PDL-1 Strong Positive Participants with TPS ≥50% was defined as the time from randomization to the date of death.
OS in PDL-1 Strong Positive Participants With TPS ≥1% Up to approximately 132 months OS in PDL-1 Strong Positive Participants with TPS ≥1% was defined as the time from randomization to the date of death.
Number of Participants Who Discontinued Study Treatment Due to an AE Up to approximately 19 months An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. The number of participants who discontinued study treatment due to an AE were reported.
Number of Participants Who Experienced an Adverse Event (AE) Up to approximately 22 months An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. The number of participants who experienced an AE were reported.
