Overall Survival (OS)

Study of Two Doses of Pembrolizumab (MK-3475) Versus Docetaxel in Previously Treated Participants With Non-Small Cell Lung Cancer (MK-3475-010/KEYNOTE-010) · Source last updated 2021-10-06

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEDIAN
Unit: Months
Interval / dispersion: 95% Confidence Interval
Time frame: Through pre-specified database cutoff date of 30 Sep 2015 (Up to approximately 24 months)

What was measured

OS was defined as the time from randomization to death due to any cause. OS was analyzed using the Kaplan-Meier method and is reported in months. Per protocol, final analysis for this primary outcome measure was performed for the first pembrolizumab course and docetaxel treatment arms, with a protocol-specified analysis data cutoff date of 30 September (Sep) 2015.

Analysis population: Per protocol, OS for the first pembrolizumab course and docetaxel treatment arms was analyzed in all randomized participants who had strongly PD-L1 positive and all PD-L1 positive OS data available and usable. Participants were included in the treatment group to which they were randomized.

Groups in this outcome

Pembrolizumab 2 mg/kg

Participants received pembrolizumab 2 mg/kg IV over 30 minutes Q3W for up to 2 years. Qualified participants who received the first course of pembrolizumab 2 mg/kg Q3W for up to 2 years, but experienced disease progression, initiated a second course of pembrolizumab at the investigator's discretion, at 200 mg IV Q3W for up to 1 year.

Pembrolizumab 10 mg/kg

Participants received pembrolizumab 10 mg/kg IV over 30 minutes Q3W for up to 2 years. Qualified participants who received the first course of pembrolizumab 10 mg/kg Q3W for up to 2 years, but experienced disease progression, initiated a second course of pembrolizumab at the investigator's discretion, at 200 mg IV Q3W for up to 1 year.

Docetaxel 75 mg/m^2

Participants received docetaxel 75 mg/m\^2 IV over 1 hour Q3W for up to 2 years. Qualified participants who received docetaxel 75 mg/m\^2 Q3W for up to 2 years, but experienced disease progression, switched over to pembrolizumab, at the investigator's discretion, at 200 mg IV Q3W for up to 2 years.
