QoL analyses from INFORM study, a phase III study of gefitinib versus placebo as maintenance therapy in advanced NSCLC.

ABSTRACT: This report aimed to provide the full results of QoL assessment in INFORM study. QoL was assessed by FACT-L questionnaire. QoL improvement ratio in gefitinib arm was higher than placebo arm (FACT-L: 46% vs. 22%, p < 0.001; TOI: 41% vs. 18%, p < 0.001; LCS: 46% vs. 22%, p < 0.001). Gefitinib prolonged time-to-worsening of QoL (FACT-L: 2.8 m vs 1.4 m, p = 0.019; TOI: 3.5 m vs 1.4 m, p = 0.006; LCS: 2.8 vs 1.4 m, p = 0.028). Patients with an improvement in QoL had longer PFS (FACT-L: 9.4 m vs. 2.8 m vs. 2.7 m, P < 0.001; TOI: 9.9 m vs. 2.8 m vs. 2.1 m, P < 0.001; LCS: 9.4 m vs. 2.9 m vs. 2.1 m, P < 0.001) and OS (FACT-L: 25.4 m vs. 19.9 m vs. 14.4 m, P = 0.003; TOI: 25.7 m vs. 19.0 m vs. 12.7 m, P = 0.002; LCS: 25.4 m vs. 19.3 m vs. 14.7 m, P = 0.004) compared with patients with stable or worsened QoL. Furthermore, in patients with good QoL at baseline, the treatment of gefitinib couldn't improve OS compared to placebo, whereas patients with low QoL experienced marginal significant improvement in OS (20.6 m vs 14.4, p = 0.051). Our study indicated that gefitinib could improve patients' QoL, confirmed the prognostic value of QoL changes during treatment, and implied patients with low QoL at baseline may be the potential population which will gain OS benefit from maintenance EGFR-TKI therapy.

Project description:BackgroundIn addition to improving survival outcomes, new oncology treatments should lead to amelioration of patients' quality of life (QoL). Herein, we examined whether QoL results correlated with PFS and OS outcomes in phase III randomized controlled trials (RCTs) investigating new systemic treatments in metastatic non-small cell lung cancer (NSCLC).MethodsThe systematic search of PubMed was conducted in October 2022. We identified 81 RCTs testing novel drugs in metastatic NSCLC and published in the English language in a PubMed-indexed journal between 2012 and 2021. Only trials reporting QoL results and at least one survival outcome between OS and PFS were selected. For each RCT, we assessed whether global QoL was "superior," "inferior," or with "non-statistically significant difference" in the experimental arm compared to the control arm.ResultsExperimental treatments led to superior QoL in 30 (37.0%) RCTs and inferior QoL in 3 (3.7%) RCTs. In the remaining 48 (59.3%) RCTs, a statistically significant difference between the experimental and control arms was not found. Of note, we found a statistically significant association between QoL and PFS improvements (X2 = 3.93, p = 0.0473). In more detail, this association was not significant in trials testing immunotherapy or chemotherapy. On the contrary, in RCTs testing target therapies, QoL results positively correlated with PFS outcomes (p = 0.0196). This association was even stronger in the 32 trials testing EGFR or ALK inhibitors (p = 0.0077). On the other hand, QoL results did not positively correlate with OS outcomes (X2 = 0.81, p = 0.368). Furthermore, we found that experimental treatments led to superior QoL in 27/57 (47.4%) trials with positive results and in 3/24 (12.5%) RCTs with negative results (p = 0.0028). Finally, we analyzed how QoL data were described in publications of RCTs in which QoL outcomes were not improved (n = 51). We found that a favorable description of QoL results was associated with sponsorship by industries (p = 0.0232).ConclusionsOur study reveals a positive association of QoL results with PFS outcomes in RCTs testing novel treatments in metastatic NSCLC. This association is particularly evident for target therapies. These findings further emphasize the relevance of an accurate assessment of QoL in RCTs in NSCLC.

Project description:IntroductionThe role of maintenance durvalumab after definitive concurrent chemoradiotherapy (CCRT) in unresectable locally advanced NSCLC with EGFR mutation or ALK translocation remains unclear. We compared the effectiveness of durvalumab maintenance therapy in groups with EGFR and ALK wild-type versus those with EGFR or ALK mutations.MethodsIn this retrospective multicenter observational study, patients with locally advanced NSCLC without progression after CCRT followed by maintenance durvalumab and available molecular test results (EGFR and ALK) were eligible. The primary objective was to compare progression-free survival (PFS) between EGFR and ALK wild-type and EGFR or ALK mutant NSCLC. Secondary objectives include overall survival according to EGFR or ALK mutation and programmed death-ligand 1 (PD-L1) expression.ResultsAmong 339 patients, 279 had wild-type EGFR/ALK, 41 had EGFR mutations and 19 had ALK translocations. The median age was 68 years with 276 male individuals (81.4%) and 63 female individuals (18.6%), 165 (49.3%) had adenocarcinoma, 149 (44.5%) had squamous cell carcinoma, and 21 (6.3%) had other histologic types, 120 (35.4%) had stage IIIA, 168 (49.6%) stage IIIB, and 51 (15.0%) had stage IIIC. Most of the patients (n = 288, 85%) achieved partial response to CCRT, two (0.6%) had a complete response, and 49 patients (14.4%) had stable disease. Excluding four patients with unknown PD-L1 tumor proportion score (TPS), 16 (4.8%) had a PD-L1 TPS of 0, 168 (50.1%) had 1 to 49, and 151 (45.1%) had 50 or higher. The median PFS was 21.4 months (95% confidence interval [CI]: 17.3-25.3) for the EGFR/ALK wild-type group and 21.0 months (95% CI: 15.7-not available [NA]) for the EGFR or ALK mutant group with no difference (p = 0.74). Significant differences occurred in PFS on the basis of PD-L1 expression with values of 13.6 (95% CI: 10.5-NA), 18.7 (95% CI: 15.1-26.9), and 24.7 (95% CI: 20.7-NA) months for TPS of 0, 1-49, and 50 or higher, respectively (p = 0.02).ConclusionsDurvalumab maintenance therapy after definitive CCRT in unresectable locally advanced NSCLC patients with EGFR or ALK mutation demonstrates comparable clinical outcomes to those with wild-type EGFR/ALK when PD-L1 expression is present.
