Study of Pembrolizumab (MK-3475) Subcutaneous (SC) Versus Pembrolizumab Intravenous (IV) Administered With Platinum Doublet Chemotherapy in Participants With Metastatic Squamous or Nonsquamous Non-Small Cell Lung Cancer (NSCLC) (MK-3475-A86)
NCT04956692 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to evaluate pembrolizumab (MK-3475) subcutaneous (SC) administration as the first-line therapy in the treatment of metastatic squamous and nonsquamous NSCLC by assessing the pharmacokinetics (PK), safety, and efficacy of pembrolizumab SC injection in combination with standard-of-care chemotherapy. The primary hypothesis of the study is Pembrolizumab SC is noninferior to pembrolizumab intravenous (IV) for Cycle 1 Area Under Curve (AUC) and Cycle 6 minimal concentration (Ctrough) at steady state. Participants who discontinue study treatment after receiving the first course of 35 administrations of pembrolizumab (approximately up to 2 years) for reasons other than disease progression or intolerability, may be eligible for a second course of pembrolizumab for up to approximately 1 additional year if they have experienced radiographic disease progression per RECIST 1.1 as assessed by BICR after stopping first course treatment.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04956692
The ClinicalTrials.gov registry entry for NCT04956692 describes a study currently listed as active not recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 531 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Merck Sharp & Dohme, which has 741 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Non-Small Cell Lung Cancer appearing as the primary indexed condition, and to 5 interventions — of which Carboplatin is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04956692 reports 20 study locations spanning 14 distinct geographic areas — top geographies include California, Florida, Tennessee. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
