Health-Related Quality of Life in KEYNOTE-010: a Phase II/III Study of Pembrolizumab Versus Docetaxel in Patients With Previously Treated Advanced, Programmed Death Ligand 1-Expressing NSCLC.

In the phase II/III KEYNOTE-010 study (ClinicalTrials.gov, NCT01905657), pembrolizumab significantly prolonged overall survival over docetaxel in patients with previously treated, programmed death ligand 1-expressing (tumor proportion score ≥ 1%), advanced NSCLC. Health-related quality of life (HRQoL) results are reported here. Patients were randomized 1:1:1 to pembrolizumab 2 or 10 mg/kg every 3 weeks or docetaxel 75 mg/m2 every 3 weeks. HRQoL was assessed using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLC) Core 30 (C30), EORTC QLQ-Lung Cancer 13 (LC13), and EuroQoL-5D. Key analyses included mean baseline-to-week-12 change in global health status (GHS)/quality of life (QoL) score, functioning and symptom domains, and time to deterioration in a QLQ-LC13 composite endpoint of cough, dyspnea, and chest pain. Patient reported outcomes compliance was high across all three instruments. Pembrolizumab was associated with better QLQ-C30 GHS/QoL scores from baseline to 12 weeks than docetaxel, regardless of pembrolizumab dose or tumor proportion score status (not significant). Compared with docetaxel, fewer pembrolizumab-treated patients had "deteriorated" status and more had "improved" status in GHS/QoL. Nominally significant improvement was reported in many EORTC symptom domains with pembrolizumab, and nominally significant worsening was reported with docetaxel. Significant prolongation in true time to deterioration for the QLQ-LC13 composite endpoint emerged for pembrolizumab 10 mg/kg compared to docetaxel (nominal two-sided p = 0.03), but not for the 2-mg/kg dose. These findings suggest that HRQoL and symptoms are maintained or improved to a greater degree with pembrolizumab than with docetaxel in this NSCLC patient population.

Health-related quality-of-life results for pembrolizumab versus chemotherapy in advanced, PD-L1-positive NSCLC (KEYNOTE-024): a multicentre, international, randomised, open-label phase 3 trial.

In the phase 3 KEYNOTE-024 trial, treatment with pembrolizumab conferred longer progression-free survival than did platinum-based therapy in patients with treatment-naive, advanced non-small-cell lung cancer (NSCLC) with a programmed cell death-ligand 1 (PD-L1) tumour proportion score of 50% or greater (PD-L1-positive). Here we report the prespecified exploratory endpoint of pembrolizumab versus chemotherapy on patient-reported outcomes (PROs). In this multicentre, international, randomised, open-label, phase 3 trial, we recruited patients with treatment-naive, stage IV NSCLC in 102 sites in 16 countries. Eligible patients had measurable disease (per RECIST version 1.1) and an Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. Patients were randomly assigned (1:1) via an interactive voice response system and integrated web response system to receive either pembrolizumab 200 mg every 3 weeks (35 cycles) or investigator-choice platinum-doublet chemotherapy (4-6 cycles or until documented disease progression or unacceptable toxicity). Randomisation was stratified according to geography, ECOG performance status, and histology. PROs were assessed at day 1 of cycles 1-3, every 9 weeks thereafter, at the treatment discontinuation visit, and at the 30-day safety assessment visit using the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 items (QLQ-C30), the EORTC Quality of Life Questionnaire Lung Cancer 13 items (QLQ-LC13), and the European Quality of Life 5 Dimensions-3 Level (EQ-5D-3L) questionnaire. The key exploratory PRO endpoints (analysed for all patients who received at least one dose of study treatment and completed at least one PRO instrument at at least one timepoint) were baseline-to-week-15 change in the QLQ-C30 global health status (GHS)/quality-of-life (QOL) score and time to deterioration of the composite of cough, chest pain, and dyspnoea in the QLQ-LC13. This study is registered with ClinicalTrials.gov, number NCT02142738, and is ongoing but no longer enrolling patients. Between Sept 19, 2014, and Oct 29, 2015, 305 patients were randomly assigned to pembrolizumab (n=154) or chemotherapy (n=151). Three patients in each group did not complete any PRO instruments at any timepoints, and so 299 patients were included in the full analysis set. Of these patients, one in each group did not complete any PRO instruments before week 15, and so were not included in analyses of change from baseline to week 15. PRO compliance was greater than 90% at baseline and approximately 80% at week 15 for both groups. Least-squares mean baseline-to-week-15 change in QLQ-C30 GHS/QOL score was 6·9 (95% CI 3·3 to 10·6) for pembrolizumab and -0·9 (-4·8 to 3·0) for chemotherapy, for a difference of 7·8 (2·9 to 12·8; two-sided nominal p=0·0020). Fewer pembrolizumab-treated patients had deterioration in the QLQ-LC13 composite endpoint than did chemotherapy-treated patients (46 [31%] of 151 patients vs 58 [39%] of 148 patients). Time to deterioration was longer with pembrolizumab than with chemotherapy (median not reached [95% CI 8·5 to not reached] vs 5·0 months [3·6 to not reached]; hazard ratio 0·66, 95% CI 0·44-0·97; two-sided nominal p=0·029). Pembrolizumab improves or maintains health-related QOL compared with that for chemotherapy, and might represent a new first-line standard of care for PD-L1-expressing, advanced NSCLC. Merck & Co.

Patient-reported outcomes following pembrolizumab or placebo plus pemetrexed and platinum in patients with previously untreated, metastatic, non-squamous non-small-cell lung cancer (KEYNOTE-189): a multicentre, double-blind, randomised, placebo-controlled

Pembrolizumab plus pemetrexed-platinum led to superior overall survival and progression-free survival, and a higher proportion of patients with a confirmed complete or partial response over placebo plus pemetrexed-platinum in the KEYNOTE-189 study. We aimed to evaluate prespecified exploratory patient-reported outcomes (PROs) in patients in KEYNOTE-189. In the multicentre, double-blind, randomised, placebo-controlled, phase 3 KEYNOTE-189 study done at 126 cancer centres in 16 countries, eligible patients aged 18 years or older with histologically or cytologically confirmed metastatic non-squamous non-small-cell lung cancer without sensitising EGFR or ALK alterations, measurable disease as per Response Evaluation Criteria in Solid Tumors (version 1.1), and an Eastern Cooperative Oncology Group performance status of 0 or 1 were enrolled. Patients were randomly assigned (2:1) to receive intravenous pembrolizumab (200 mg) or saline placebo every 3 weeks for up to 2 years (35 cycles); all patients received four cycles of intravenous pemetrexed (500 mg/m2) with carboplatin (5 mg/mL per min) or cisplatin (75 mg/m2; investigator's choice) every 3 weeks for four cycles, followed by pemetrexed maintenance therapy every 3 weeks. Permuted block randomisation (block size six) was done with an interactive voice-response system and stratified by PD-L1 expression, choice of platinum, and smoking status. Patients, investigators, and other study personnel were unaware of treatment assignment. The European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30 (QLQ-C30) and Lung Cancer 13 (QLQ-LC13) were administered at cycles 1-5, every three cycles thereafter during year 1, and every four cycles during years 2-3. The primary endpoints (overall survival and progression-free survival) have been published previously. Key PRO endpoints were change from baseline to week 12 (during chemotherapy) and week 21 (following chemotherapy) in QLQ-C30 global health status/quality of life (GHS/QOL) score, and time to deterioration in cough, chest pain, or dyspnoea. PROs were analysed in all randomly assigned patients who received at least one dose of study medication and who completed at least one PRO assessment, and the results are provided with two-sided, nominal p values. This ongoing study is registered with ClinicalTrials.gov, number NCT02578680. Between Feb 26, 2016, and March 6, 2017, 616 patients were enrolled; median follow-up was 10·5 months (range 0·2-20·4) as of data cutoff on Nov 8, 2017. 402 (99%) of 405 patients in the pembrolizumab plus pemetrexed-platinum group and 200 (99%) of 202 patients in the placebo plus pemetrexed-platinum-treated group completed at least one PRO assessment. At baseline, 359 (89%) of 402 patients in the pembrolizumab plus pemetrexed-platinum group and 180 (90%) of 200 in the placebo plus pemetrexed-platinum group were compliant with QLQ-C30; at week 12, 319 (90%) of 354 and 149 (89%) of 167 patients were compliant, respectively; and at week 21, 249 (76%) of 326 and 91 (64%) of 143 patients were compliant, respectively. From baseline to week 12, GHS/QOL scores were maintained with both pembrolizumab plus pemetrexed-platinum (least-squares mean change: 1·0 point [95% CI -1·3 to 3·2] increase) and placebo plus pemetrexed-platinum (-2·6 points [-5·8 to 0·5] decrease; between-group difference: 3·6 points [-0·1 to 7·2]; p=0·053). From baseline to week 21, GHS/QOL scores were better maintained with pembrolizumab plus pemetrexed-platinum (least-squares mean change: 1·3 points [95% CI -1·2 to 3·6] increase) than with placebo plus pemetrexed-platinum (-4·0 points [-7·7 to -0·3] decrease; between-group difference: 5·3 points [1·1 to 9·5]; p=0·014). Median time to deterioration in cough, chest pain, or dyspnoea was not reached (95% CI 10·2 months to not reached) with pembrolizumab plus pemetrexed-platinum, and was 7·0 months (4·8 months to not reached) with placebo plus pemetrexed-platinum (hazard ratio 0·81 [95% CI 0·60-1·09], p=0·16). The addition of pembrolizumab to standard chemotherapy maintained GHS/QOL, with improved GHS/QOL scores at week 21 in the pembrolizumab plus chemotherapy group compared with the placebo plus chemotherapy group. These data further support use of pembrolizumab plus pemetrexed-platinum as first-line therapy for patients with metastatic non-squamous non-small-cell lung cancer. Merck Sharp & Dohme.

Health-related quality of life in patients with microsatellite instability-high or mismatch repair deficient metastatic colorectal cancer treated with first-line pembrolizumab versus chemotherapy (KEYNOTE-177): an open-label, randomised, phase 3 trial.

In the KEYNOTE-177 study, pembrolizumab monotherapy provided statistically significant and clinically meaningful improvements in progression-free survival versus chemotherapy as first-line treatment in patients with microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer. To further support the efficacy and safety findings of the KEYNOTE-177 study, results of the health-related quality of life (HRQOL) analyses are reported here. KEYNOTE-177 is an open-label, randomised, phase 3 trial being done at 192 cancer centres in 23 countries, in patients aged 18 years and older with microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer, with an Eastern Cooperative Oncology Group performance status of 0 or 1, and who had not received previous systemic therapy for metastatic disease. Eligible patients were randomly assigned (1:1) centrally by use of interactive voice response or integrated web response technology to receive pembrolizumab 200 mg intravenously every 3 weeks or investigator's choice chemotherapy (mFOLFOX6 [leucovorin, fluorouracil, and oxaliplatin] or FOLFIRI [leucovorin, fluorouracil, and irinotecan] intravenously every 2 weeks with or without intravenous bevacizumab or cetuximab). Patients and investigators were not masked to treatment assignment. The primary endpoints were progression-free survival (previously reported) and overall survival (data to be reported at the time of the final analysis). HRQOL outcomes were evaluated as prespecified exploratory endpoints. The analysis population comprised all randomly assigned patients who received at least one dose of study treatment and completed at least one HRQOL assessment. HRQOL outcomes were mean change from baseline to prespecified week 18 in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and EORTC Quality of Life Questionnaire-Colorectal 29 (EORTC QLQ-CR29) scale and item scores, and in the EuroQoL 5 Dimensions 3 Levels (EQ-5D-3L) visual analogue scale and health utility scores; the proportion of patients with improved, stable, or deteriorated scores from baseline to prespecified week 18 in EORTC QLQ-C30 scales and items; and time to deterioration in EORTC QLQ-C30 global health status/quality of life (GHS/QOL), physical functioning, social functioning, and fatigue scores and EORTC QLQ-CR29 urinary incontinence scores. The threshold for a small and clinically meaningful mean difference in EORTC QLQ-C30 score was 5-8 points. This study is registered with ClinicalTrials.gov, NCT02563002 and is ongoing; recruitment is closed. Between Feb 11, 2016, and Feb 19, 2018, 307 patients were enrolled and randomly assigned to receive pembrolizumab (n=153) or chemotherapy (n=154). The HRQOL analysis population comprised 294 patients (152 receiving pembrolizumab and 142 receiving chemotherapy). As of Feb 19, 2020, median time from randomisation to data cutoff was 32·4 months (IQR 27·7-37·8). Least squares mean (LSM) change from baseline to prespecified week 18 showed a clinically meaningful improvement in EORTC QLQ-C30 GHS/QOL scores with pembrolizumab versus chemotherapy (between-group LSM difference 8·96 [95% CI 4·24-13·69]; two-sided nominal p=0·0002). Median time to deterioration was longer with pembrolizumab versus chemotherapy for GHS/QOL (hazard ratio 0·61 [95% CI 0·38-0·98]; one-sided nominal p=0·019), physical functioning (0·50 [95% CI 0·32-0·81]; one-sided nominal p=0·0016), social functioning (0·53 [95% CI 0·32-0·87]; one-sided nominal p=0·0050), and fatigue scores (0·48 [95% CI 0·33-0·69]; one-sided nominal p<0·0001). Pembrolizumab monotherapy led to clinically meaningful improvements in HRQOL compared with chemotherapy in patients with previously untreated microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer. These data, along with the previously reported clinical benefits, support pembrolizumab as a first-line treatment option for this population.
