O16.01 - Impact of tumor burden on the overall survival analysis of the LUME-Lung 1 study: a randomized, double-blind phase 3 trial of nintedanib (BIBF 1120) + docetaxel in NSCLC patients progressing after first-line chemotherapy (ID 3284)

Nintedanib is an orally available potent anti-angiogenic agent inhibiting the isoforms of VEGFR, PDGFR and FGFR. LUME-Lung 1 is a placebo-controlled phase 3 trial of nintedanib + docetaxel in second-line NSCLC patients.
Patients with stage IIIB/IV or recurrent NSCLC after failure of first-line chemotherapy were stratified by histology, ECOG PS, prior bevacizumab and brain metastases, and were randomised to nintedanib 200 mg bid + docetaxel 75 mg/m q21d (n=655), or placebo + docetaxel (n=659). The primary endpoint was centrally reviewed PFS after 714 events. The key secondary endpoint was OS after 1,121 events. Predefined sensitivity analyses used baseline sum of longest diameters of target lesions (SLD) and stratification factors, as covariates in the Cox model.
The study met its primary endpoint demonstrating a statistically significant improvement in PFS that translated into a 21% reduction in the risk of progression in patients treated with the combination of nintedanib + docetaxel vs placebo + docetaxel (HR 0.79; CI: 0.68, 0.92; p=0.0019; median 3.4 vs 2.7 months), regardless of histology (adenocarcinoma HR 0.77, CI: 0.62, 0.96; p=0.0193; squamous HR 0.77, CI: 0.62, 0.96; p=0.0200). OS was significantly prolonged in adenocarcinoma patients treated with the combination of nintedanib + docetaxel vs placebo + docetaxel (HR 0.83; CI: 0.70, 0.99; p=0.0359; median 12.6 vs 10.3 months) but not in squamous cell carcinoma patients (HR 1.01; CI: 0.85, 1.21; p=0.8908; median 8.6 vs 8.7 months). The intent-to-treat (ITT) analysis of OS in all study patients showed a 1-month improvement that did not reach statistical significance (HR 0.94; CI 0.83, 1.05; p=0.272; median 10.1 vs 9.1 months). When adjusted for SLD, however, a significant OS benefit was seen for the ITT population (HR 0.88; CI: 0.78, 0.99; p=0.0365). Further analyses showed that the impact of SLD was reflected in the squamous cell carcinoma population (HR 0.92; CI: 0.77, 1.10; p=0.3649), with the greatest impact observed for squamous cell carcinoma patients with a large SLD. An impact of SLD was also seen in adenocarcinoma patients but to a lesser extent (HR 0.81; CI:0.69, 0.97; p=0.0186), as compared with the squamous cell carcinoma population. The most common AEs reported for the ITT population were diarrhea (any: 42.3 vs 21.8%; Gr ≥3: 6.6 vs 2.6%) and ALT elevations (any: 28.5 vs 8.4%; Gr ≥3: 7.8 vs 0.9%). Incidence of CTCAE Gr ≥3 AEs was 71.3 vs 64.3%. Withdrawals due to AEs (22.7 vs 21.7%) were similar in both arms, as were Gr ≥3 hypertension, bleeding or thrombosis.
Nintedanib + docetaxel significantly reduced the risk of progression in NSCLC patients independent of histology. Adjustment for tumor burden, as represented by the SLD, led to a significant reduction in the risk of death. AEs were generally manageable with dose reductions and symptomatic treatment.

P3.11-040 - Analysis of patient-reported outcomes from the LUME-Lung 1 trial: a randomized, double-blind, placebo-controlled phase 3 study in second-line advanced non-small cell lung cancer (NSCLC) patients (ID 2812)

Nintedanib is an oral, twice-daily angiokinase inhibitor targeting VEGFR-1–3, PDGFR-α/β and FGFR-1–3. LUME-Lung 1 is a placebo-controlled phase III trial investigating nintedanib plus docetaxel in advanced NSCLC patients after failure of first-line chemotherapy.
Stage IIIB/IV or recurrent NSCLC patients were randomised to receive nintedanib 200 mg bid plus docetaxel 75 mg/m q21d (n=655), or placebo plus docetaxel (n=659). The primary endpoint was centrally reviewed progression-free survival (PFS) analysed after 714 events; the key secondary endpoint was overall survival (OS) analysed hierarchically after 1121 events, first in adenocarcinoma patients and then all patients. Quality of Life (QoL) was included as a secondary endpoint. Lung cancer symptoms and health-related QoL were assessed every 21 days until the first follow-up visit using the EORTC (QLQ-C30/LC13) and EQ-5D questionnaires. Changes of ≥10 points as compared with baseline were considered clinically significant. Analyses of cough, dyspnoea and pain symptoms were prespecified. Time to deterioration (TTD, first 10-point worsening from baseline) was analysed using a stratified log-rank test. An exploratory analysis of all subscales/items from the EORTC QLQ-C30/LC13 questionnaires estimated the respective hazard ratios for TTD using a Cox proportional hazards model.
LUME-Lung 1 showed that nintedanib in combination with docetaxel significantly prolonged PFS for all patients regardless of histology (3.4 vs 2.7 months; HR 0.79, 95% CI: 0.68–0.92; p=0.0019), with a trend for improved median OS (10.1 vs 9.1 months; HR 0.94, 95% CI: 0.83–1.05; p=0.272) and significantly improved OS in patients with adenocarcinoma (HR: 0.83; p=0.0359; median 10.3 to 12.6 months). The most common AEs were diarrhoea and reversible ALT elevations. With respect to the QoL assessment, there was a high compliance rate of >80% until treatment course 25 for QLQ-LC13 and QLQ-C30 in both treatment arms. The addition of nintedanib to docetaxel did not influence TTD for cough (HR 0.90; 95% CI: 0.77–1.05; p=0.1858), dyspnoea (HR 1.05; 95% CI: 0.91–1.20; p=0.5203) or pain (HR 0.95; 95% CI: 0.82–1.09; p=0.4373), and maintained global health status/QoL (HR 0.952; 95% CI: 0.83–1.10). There was a significant deterioration in scores for nausea and vomiting, appetite loss and diarrhoea. The results were similar for adenocarcinoma patients with respect to cough (HR 0.97; 95% CI: 0.78–1.20; p=0.7744), dyspnoea (HR 1.04; 95% CI: 0.86–1.26; p=0.6813) and pain (HR 0.93; 95% CI: 0.76–1.13; p=0.4785); however, there was a trend for improved global health status/QoL (HR 0.86; 95% CI: 0.71–1.05). For squamous cell carcinoma patients, there was a trend for delayed TTD for cough (HR 0.84; 95% CI: 0.66–1.07; p=0.1561) and a maintained global health status/QoL (HR 0.975; 95% CI: 0.788–1.206). Further analyses are ongoing and will be presented at the congress.
In second-line NSCLC patients, docetaxel plus nintedanib did not result in any significant improvements in cough, dyspnoea or pain compared with placebo and docetaxel. However, PFS was improved in patients of all histologies receiving docetaxel and nintedanib, and OS was improved in patients with adenocarcinoma histology without adversely affecting self-reported QoL.
