Duration of Response (DOR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)

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) · Source last updated 2024-10-08

What was measured

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.

Analysis population: The Intent-To-Treat population consisted of all randomized participants, regardless of whether or not they received study treatment, who demonstrated a confirmed response (CR or PR). Participants were included in the treatment arm to which they were randomized.

Groups in this outcome

Pembrolizumab + Chemotherapy Combo

Participants received pembrolizumab 200 mg by intravenous (IV) infusion prior to chemotherapy on Day 1 of each 21-day cycle (Q3W) for up to 35 cycles (\~ 2 years) PLUS Investigator's choice of paclitaxel (200 mg/m\^2 by IV infusion on Day 1 of each 21-day cycle for 4 cycles) or nab-paclitaxel (100 mg/m\^2 by IV infusion on Days 1, 8, 15 of each 21-day cycle for 4 cycles) PLUS carboplatin Area Under Curve (AUC) 6 by IV infusion on Day 1 of each 21-day cycle for 4 cycles. Participants who received pembrolizumab 200 mg IV Day 1 of 21-day cycle for up to 2 years, but experienced disease progression, were eligible to receive a second course of pembrolizumab 200 mg IV Day 1 of 21-day cycle, at the investigator's discretion, for 17 cycles (\~ 1 year additional).

Placebo + Chemotherapy

Participants received normal saline as placebo by IV infusion prior to chemotherapy on Day 1 of 21-day cycle for up to 35 cycles (\~ 2 years) PLUS Investigator's choice of paclitaxel (200 mg/m\^2 by IV infusion on Day 1 of each 21-day cycle for 4 cycles) or nab-paclitaxel (100 mg/m\^2 by IV infusion on Days 1, 8, 15 of each 21-day cycle for 4 cycles) PLUS carboplatin AUC 6 by IV infusion on Day 1 of each 21-day cycle for 4 cycles. Participants with documented disease progression following placebo chemotherapy combo could switch-over to receive pembrolizumab for up to 35 cycles (\~ 2 years). Eligible cross over participants who stopped pembrolizumab and had stable disease but progressed after discontinuation, initiated a second course of pembrolizumab at the investigator's discretion for up to 17 cycles (\~ 1 year additional).
