Current Primary Outcome Measures ^ICMJE

Progression-free Survival (PFS) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per Response Criteria in Solid Tumors version 1.1 (RECIST 1.1), PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. Note: The appearance of ≥1 new lesions was also considered PD. PFS as assessed by blinded independent central review per RECIST 1.1 is presented.
Overall Survival (OS) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
OS was defined as the time from randomization to death due to any cause. OS is presented.

Original Primary Outcome Measures ^ICMJE

Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by a blinded central imaging vendor [ Time Frame: Up to approximately 2 years ]
Overall Survival (OS) [ Time Frame: Up to approximately 2 years ]

Current Secondary Outcome Measures ^ICMJE

Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
ORR was defined as the percentage of participants who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) as assessed by RECIST 1.1. ORR as assessed by blinded independent central review per RECIST 1.1 is presented.
Duration of Response (DOR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
For participants who demonstrated a confirmed response (Complete Response [CR]: Disappearance of all target lesions or Partial Response [PR]: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR was defined as the time from first documented evidence of CR or PR until disease progression as assessed by RECIST 1.1 or death. DOR as assessed by blinded independent central review per RECIST 1.1 is presented.
Number of Participants Who Experienced an Adverse Event (AE) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
An AE was defined as any untoward medical occurrence in a participant administered study treatment and which did not necessarily have to have a causal relationship with this treatment. The number of participants who experienced an AE is presented.
Number of Participants Who Discontinued Study Treatment Due to an Adverse Event (AE) [ Time Frame: Up to approximately 19 months (Database cutoff date of 03-Apr-2018) ]
The number of participants who discontinued study treatment due to an AE is presented.

Descriptive Information

Brief Title ^ICMJE

A Study of Carboplatin-Paclitaxel/Nab-Paclitaxel Chemotherapy With or Without Pembrolizumab (MK-3475) in Adults With First Line Metastatic Squamous Non-small Cell Lung Cancer (MK-3475-407/KEYNOTE-407)

Official Title ^ICMJE

A Randomized, Double-Blind, Phase III Study of Carboplatin-Paclitaxel/Nab-Paclitaxel Chemotherapy With or Without Pembrolizumab (MK-3475) in First Line Metastatic Squamous Non-small Cell Lung Cancer Subjects (KEYNOTE-407)

Brief Summary

This is a study of carboplatin and paclitaxel or nano particle albumin-bound paclitaxel (nab-paclitaxel) with or without pembrolizumab (MK-3475, KEYTRUDA®) in adults with first line metastatic squamous non-small cell lung cancer (NSCLC).

The primary hypotheses are that treatment with pembrolizumab prolongs: 1) Progression-free Survival (PFS) by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by a blinded central imaging vendor compared to placebo, and 2) Overall Survival (OS).

After analysis of interim results was conducted, the protocol was amended (Amendment 5) to allow participants the option to discontinue placebo in the control arm and to switch to pembrolizumab in the event of documented progressive disease as assessed by central review.
