Trial Outcomes & Findings for A Study of Pembrolizumab (MK-3475) in Combination With Etoposide/Platinum (Cisplatin or Carboplatin) for Participants With Extensive Stage Small Cell Lung Cancer (MK-3475-604/KEYNOTE-604) (NCT NCT03066778)

NCT ID: NCT03066778

Last Updated: 2022-10-03

Results Overview

PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. PD, as determined by RECIST 1.1, was defined as ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD. For this study, RECIST 1.1 was modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The PFS was calculated using the non-parametric Kaplan-Meier method for censored data and presented for the first course of study treatment per protocol.

Participant Flow

Participants in the pembrolizumab+ chemotherapy (etoposide/platinum \[EP\]) arm were eligible to receive second course treatment with pembrolizumab if they met criteria for re-treatment. Per protocol, response, progression, or patient reported outcomes during the second course were not counted towards efficacy outcome measures and adverse events during the second course were not counted towards safety outcome measures.

One participant who was randomized to the pembrolizumab+EP arm was inadvertently treated with placebo+EP. For efficacy analyses this participant will be included in the arm they were initially randomized into and for safety analyses the participant will be included by treatment received.

During each 21-day cycle, participants received pembrolizumab 200 mg intravenously (IV) on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an area under the plasma drug concentration-time curve \[AUC\] 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1). Participants who stopped pembrolizumab as a result of obtaining a response of stable disease (SD), partial response (PR), complete response (CR) or those who stopped after receiving pembrolizumab for 24 months for reasons other than disease progression or intolerability, were eligible for up to an additional 1 year of treatment after progressive disease if they met the criteria for retreatment.
Placebo+EP
During each 21-day cycle, participants received placebo (normal saline solution) IV on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an AUC 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1).

ORR was defined as the percentage of participants who achieve a best objective response of complete response (CR) or partial response (PR) per RECIST 1.1. CR was defined as the disappearance of all target lesions. PR was defined as ≥30% decrease in the sum of diameters of target lesions taking as a reference the baseline sum diameters. In this study, RECIST 1.1 was modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ. The ORR was calculated using the Miettinen \& Nurminen method stratified by type of platinum therapy (carboplatin or cisplatin), baseline ECOG performance status (0 or 1), and baseline LDH (≤ or \> upper limit of normal) and presented for the first course of study treatment per protocol.

An adverse event was defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which did not necessarily have to have had a causal relationship with this treatment. An adverse event could therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that was temporally associated with the use of the Sponsor's product, was also an adverse event. The number of participants who experienced an AE was reported for each arm according to the treatment received and is presented for the first course of study treatment per protocol.

EORTC QLQ-C30 is a questionnaire that rates the overall quality of life in cancer participants. The first 28 questions use a 4-point scale (1=not at all to 4=very much) for evaluating function (physical, role, social, cognitive, emotional), symptoms (diarrhea, fatigue, dyspnea, appetite loss, insomnia, nausea/vomiting, constipation, and pain) and financial difficulties. The last 2 questions use a 7-point scale (1=very poor to 7=excellent) to evaluate overall health and quality of life. Scores are transformed to a range of 0 to 100 using a standard EORTC algorithm. Change from baseline scores were calculated using a constrained longitudinal data analysis (cLDA) model. Negative change from baseline values indicated deterioration in health status or functioning and positive changes indicated improvement. Data are presented for the first course of study treatment per protocol.

SECONDARY outcome

Timeframe: Day 1 of Cycles 1-9, Day 1 of every other cycle for Cycles 10-17 and 30 days after last dose of study treatment (Up to approximately 27 months)

Population: All participants who received at least 1 dose of study medication and had non-missing assessments.

TTD in patient-reported lung cancer symptoms of cough (QLQ-LC-13 Item 1), chest pain (QLQ-LC-13 Item 10), and dyspnea (QLQ-C30 Item 8) was a composite endpoint defined as the time to first onset of ≥10 point deterioration from baseline in an item confirmed by a second adjacent ≥10 point deterioration. The QLQ-LC13 consists of 13 measures of lung cancer symptoms and side effects from chemotherapy and radiation. It is scored on a 4-point scale (1=none, 2=a little, 3=quite a bit, 4=very much). Scores were transformed to a range of 0 to 100 using a standard algorithm. Higher scores represented increasing symptom severity. TTD was calculated using the product-limit Kaplan-Meier method for censored data and is presented for the first course of study treatment per protocol.

During each 21-day cycle, participants received pembrolizumab 200 mg intravenously (IV) on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an area under the plasma drug concentration-time curve \[AUC\] 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1). Participants who stopped pembrolizumab as a result of obtaining a response of stable disease (SD), partial response (PR), complete response (CR) or those who stopped after receiving pembrolizumab for 24 months for reasons other than disease progression or intolerability, were eligible for up to an additional 1 year of treatment after progressive disease if they met the criteria for retreatment.

Pembrolizumab+EP
n=223 participants at risk
During each 21-day cycle, participants received pembrolizumab 200 mg intravenously (IV) on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an area under the plasma drug concentration-time curve \[AUC\] 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1). Participants who stopped pembrolizumab as a result of obtaining a response of stable disease (SD), partial response (PR), complete response (CR) or those who stopped after receiving pembrolizumab for 24 months for reasons other than disease progression or intolerability, were eligible for up to an additional 1 year of treatment after progressive disease if they met the criteria for retreatment.
Placebo+EP
n=223 participants at risk
During each 21-day cycle, participants received placebo (normal saline solution) IV on Day 1 PLUS etoposide 100 mg/m\^2 IV on Days 1, 2 and 3 PLUS investigator's choice of platinum therapy (carboplatin titrated to an AUC 5 IV on Day 1 OR cisplatin 75 mg/m\^2 IV on Day 1).
