A Clinical Study of Pembrolizumab (+) Berahyaluronidase Alfa (MK-3475A) to Treat Newly-diagnosed Metastatic Non-small Cell Lung Cancer (MK-3475A-F84)

A Phase 3 Randomized, Open-label Clinical Study to Evaluate the Pharmacokinetics and Safety of Subcutaneous Pembrolizumab Coformulated With Hyaluronidase (MK-3475A) Versus Intravenous Pembrolizumab, in the First-line Treatment of Participants With Metastatic Non-small Cell Lung Cancer With PD-L1 TPS 50% or Greater

Brief summary

Researchers are looking for new ways to treat non-small cell lung cancer (NSCLC) that is metastatic, which means cancer has spread to other parts of the body. Some people with metastatic NSCLC are treated with pembrolizumab, an immunotherapy treatment that is given into a vein as an intravenous (IV) infusion. Pembrolizumab (+) Berahyaluronidase alfa is pembrolizumab that is given under the skin as a subcutaneous (SC) injection. The goal of this study is to learn what happens to pembrolizumab in a person's body over time when it is given as an IV infusion or SC injection.

Inclusion criteria

* Histologically or cytologically confirmed diagnosis of squamous or nonsquamous non-small cell lung cancer (NSCLC). * Measurable disease as assessed by the local site investigator/radiology.

Exclusion criteria

* Diagnosis of small cell lung cancer or, for mixed tumors, presence of small cell elements. * Received prior systemic anticancer therapy for their metastatic NSCLC. * Known additional malignancy that is progressing or has required active treatment within the past 3 years. * Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. * Active autoimmune disease that has required systemic treatment in the past 2 years. * History of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease. * Active infection requiring systemic therapy.

Design outcomes

Primary

MeasureTime frameDescription
Area Under the Curve (AUC) of Pembrolizumab Measured After the First DoseAt designated time points (up to approximately 14 months)AUC is defined as area under curve exposure. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine AUC.
Trough Concentration (Ctrough) of Pembrolizumab Measured at Steady StateAt designated time points (Up to ~15 months)Ctrough is defined as the trough concentration at steady-state. Blood samples collected pre-dose and at multiple timepoints post-dose will be used to determine Ctrough

Secondary

MeasureTime frameDescription
Number of Participants Who Experience an AE- All ParticipantsUp to approximately 28 monthsAn AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.
Number of Participants Who Discontinue Study Intervention Due to an AEUp to approximately 25 monthsAn AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.
