Details and patient eligibility

About

The purpose of this study is to compare overall survival (OS) and progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR). Hypothesis (H1): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab plus olaparib is superior to concurrent chemoradiation therapy alone with respect to PFS per RECIST 1.1 by BICR. Hypothesis (H2): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab is superior to concurrent chemoradiation therapy alone with respect to PFS per RECIST 1.1 by BICR. Hypothesis (H3): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab plus olaparib is superior to concurrent chemoradiation therapy alone with respect to OS. Hypothesis (H4): Concurrent chemoradiation therapy with pembrolizumab followed by pembrolizumab is superior to concurrent chemoradiation therapy alone with respect to OS.

Inclusion criteria

Has pathologically (histologically or cytologically) confirmed Small Cell Lung Cancer (SCLC).

Note: Note: Participants with histology showing a mixed tumor with small cell and non-small cell elements are not eligible.

  • Has Limited-Stage SCLC (Stage I-III, by AJCC 8th Edition Cancer Staging), and can be safely treated with definitive radiation doses.
  • Has no evidence of metastatic disease by whole body positron emission tomography /computed tomography (PET/CT scan), CT or magnetic resonance imaging (MRI) scans
  • Has at least 1 lesion that meets the criteria for being measurable, as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1)
  • Has not received prior treatment (chemotherapy or radiotherapy or surgery resection) of LS-SCLC.
  • Is not expected to require tumor resection during the course of the study.
  • Must submit a pre-treatment tumor tissue sample (formalin-fixed, paraffin embedded blocks are preferred to slides) including cytologic sample, if tissue sample unavailable.
  • Has Eastern Cooperative Oncology Group (ECOG) Performance score 0 or 1 assessed within 7 days prior to the first administration of study intervention.
  • Has a life expectancy of at least 6 months.
  • Has adequate organ function.
  • Male and female participants who are not pregnant and of childbearing potential must follow contraceptive guidance during the treatment period and for the time needed to eliminate each study intervention.
  • Male and female participants who are at least 18 years of age at the time of signing the information consent.
  • Male participants must refrain from donating sperm during the treatment period and for the time needed to eliminate each study intervention.

Abstains from breastfeeding during the study intervention period and for at least the following period after the last study intervention:

  • Pembrolizumab: 120 days
  • Olaparib: 7 days

Exclusion criteria

  • Has history, current diagnosis, or features suggestive of myelodysplastic syndrome/ acute myeloid leukemia (MDS/AML).
  • Has received prior therapy with an anti-programmed cell death 1 (anti-PD-1), anti-programmed cell death ligand 1 (anti-PDL1), or anti- programmed cell death ligand 2 (anti-PD-L2) agent or with an agent directed to another stimulatory or coinhibitory T-cell receptor
  • Has received prior therapy with olaparib or with any other polyadenosine 5'diphosphoribose (polyADP ribose) polymerization (PARP) inhibitor.
  • Had major surgery <4 weeks prior to the first dose of study intervention (except for placement of vascular access).
  • Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention.
  • 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 the first dose of study intervention.
  • Has a known additional malignancy that is progressing or has required active treatment within the past 5 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, or carcinoma in situ (e.g., breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
  • Has severe hypersensitivity (≥ Grade 3) to study intervention and/or any of its excipients.
  • Has an active autoimmune disease that has required systemic treatment in past 2 years
  • Has a history of (non-infectious) pneumonitis/interstitial lung disease that requires steroids
  • Has an active infection requiring systemic therapy.
  • Has a known history of human immunodeficiency virus (HIV) infection or Hepatitis B or known active Hepatitis C virus infection.
