Study population: Patients identified in the electronic health record data source with metastatic EGFR/ALK-negative non-small cell lung cancer initiating treatment with the study drugs (pemetrexed, cisplatin/carboplatin, pembrolizumab)

Brief summary: The goal of this non-interventional study is to emulate the KEYNOTE-189 randomized controlled trial of pembrolizumab for the treatment of metastatic non-small cell lung cancer using real-world, electronic health record data. The main questions this study aims to answer are:

1. Do patients with metastatic non-small cell lung cancer (NSCLC) treated with pemetrexed, cisplatin/carboplatin, and pembrolizumab have improved real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) compared with patients treated with pemetrexed and cisplatin/carboplatin alone?
2. How do the results of this non-interventional study compare to those of the KEYNOTE-189 randomized controlled trial?

Detailed description: The Coalition to Advance Real-World Evidence through Randomized Controlled Trial Emulation (CARE) Initiative is a program designed to build an empirical evidence base for the use of real-world data (RWD) in clinical and regulatory decision-making. Using randomized controlled trials (RCTs) as a benchmark for causal effect estimates, a series of RCT emulations will be conducted across varying trials, real world data sources, and study design elements to better understand under what conditions non-interventional studies, using data generated during routine clinical care, can provide reliable conclusions about drug effectiveness.

In this study, real-world electronic health record (EHR) data will be used to emulate the KEYNOTE-189 efficacy trial of pembrolizumab as first-line therapy in patients with metastatic non-small cell lung cancer (NSCLC) without epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) sensitizing mutations. Similarly to the KEYNOTE-189 trial, this study will compare real-world overall survival (rwOS) and real-world progression-free survival (rwPFS) between patients who initiate pemetrexed, platinum-based chemotherapy, and pembrolizumab, and patients who initiate pemetrexed and platinum-based chemotherapy alone.

Eligibility criteria: Inclusion Criteria:

* Non-small cell lung cancer (NSCLC) diagnosis
* Histology not indicative of squamous cell carcinoma

* Epidermal growth factor receptor (EGFR) and Anaplastic lymphoma kinase (ALK)-negative or Kirsten rat sarcoma viral oncogene homolog (KRAS)-positive
* No prior systemic treatment for metastatic NSCLC
* No record of adjuvant or neoadjuvant therapy in the 12 months before metastatic diagnosis
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or missing or Karnofsky performance status \&gt;=70 or missing
* No lab results indicating inadequate organ function, as defined in the KEYNOTE-189 RCT protocol

Exclusion Criteria:

* Radiation therapy to the lung \>30 Gy in the 6 months before study drug initiation
* Prior diagnosis of clinically active diverticulitis, intra-abdominal abscess, or gastrointestinal obstruction
* Diagnosis of a second primary malignant neoplasm
* Diagnosis of brain, central nervous system, and/or spinal cord metastases
* Diagnosis of autoimmune disease and treatment with corticosteroids or immunosuppressive drugs after diagnosis and within the 2 years prior to study drug initiation
* Treatment with a non-topical systemic steroid in each of the 6 months prior to study drug initiation
* Prior treatment with pembrolizumab or any other anti-PD-1, PD-L1, PD-L2 agent or an antibody targeting other immuno-regulatory receptors or mechanisms
* Treatment with non-topical antibiotics, antifungals, or antivirals within 2 weeks after an infection diagnosis in the month prior to study drug initiation
* Diagnosis of human immunodeficiency virus infection
* Diagnosis of acute hepatitis B or C
* Diagnosis of ascites or plural effusion in the 3 months prior to study drug initiation
* Prior diagnosis of interstitial lung disease or diagnosis of pneumonitis and record of treatment with glucocorticoids within 30 days

measure: Real-world progression-free survival (rwPFS)
timeFrame: From study treatment initiation until the date of disease progression, death from any cause or censoring, whichever came first, assessed up to 20.4 months.
