P3.02a-025 - PROs With Ceritinib Versus Chemotherapy in Patients With Previously Untreated ALK-rearranged Nonsquamous NSCLC (ASCEND-4) (ID 5128)
14:30 - 15:45 | Author(s): S.L. Geater
Here, we present the patient-reported outcomes (PROs) of ceritinib versus chemotherapy as first-line treatment for advanced ALK+ NSCLC.
Untreated, ALK+, advanced, nonsquamous NSCLC patients (N=376) were randomized (1:1) to ceritinib 750 mg/day (n=189) or chemotherapy (n=187; [pemetrexed 500 mg/m[2 ]plus cisplatin 75 mg/m or carboplatin AUC 5-6] for 4 cycles followed by maintenance pemetrexed). PROs were assessed using EORTC quality-of-life questionnaire (QLQ-C30), the lung cancer module (QLQ-LC13), Lung Cancer Symptom Scale (LCSS), and EQ-5D.
Median treatment exposure was 66.4 weeks for ceritinib and 26.9 weeks for chemotherapy. PRO compliance was high, ≥80% at most timepoints. Ceritinib significantly prolonged time to deterioration of lung cancer-specific symptoms (pain, dyspnea, and cough) versus chemotherapy in both LCSS and QLQ-LC13 instruments (composite endpoints for LCSS, HR=0.61 [0.41, 0.90]; and QLQ-LC13, HR=0.48 [0.34, 0.69]). Time to deterioration in LC13 questionnaire was significantly longer with ceritinib versus chemotherapy (23.6 [20.7, NE] vs 12.6 [8.9, 14.9] months) (Table). In the QLQ-C30 instrument, 4 of 5 functional domains and 6 of 9 symptom scales improved with ceritinib (P< 0.05); 2 scales related to gastrointestinal symptoms indicated deterioration for ceritinib. In agreement with most other scales showing symptom improvement, ceritinib demonstrated significant improvements in Global Health Status/QoL in the same instrument (QLQ-C30, P<0.001) as well as for EQ-5D-5L index (P<0.001) and EQ-5D-5L VAS (P<0.05 from cycle 13 until 49). Figure 1
Untreated ALK+ NSCLC patients experienced significantly greater improvements in lung cancer-specific symptoms on treatment with ceritinib. General health status was significantly improved with ceritinib versus chemotherapy. Overall, PRO results from all 4 instruments independently showed improvements highlighting the consistency and robustness of these findings.

PL03.07 - First-line Ceritinib Versus Chemotherapy in Patients With ALK-rearranged (ALK+) NSCLC: A Randomized, Phase 3 Study (ASCEND-4) (Abstract under Embargo until December 6, 7:00 CET) (ID 4987)
08:35 - 10:25 | Author(s): S.L. Geater
Here, we report results of ceritinib versus chemotherapy as first-line treatment for advanced ALK+ NSCLC.
Untreated ALK+ (IHC confirmed), advanced, nonsquamous NSCLC patients (N=376; median age, 54 years) were randomized (1:1) to ceritinib 750 mg/day (n=189 [59 with brain metastases (BM)]) or chemotherapy (n=187 [62 with BM]; [pemetrexed 500 mg/m plus cisplatin 75 mg/m or carboplatin AUC 5-6] for 4 cycles followed by maintenance pemetrexed), stratified by WHO PS (0 vs 1-2), BM at screening, and prior neo-/adjuvant chemotherapy. Crossover from chemotherapy to ceritinib was allowed at progression (n=80 crossed-over).
Median treatment exposure was 66.4 weeks for ceritinib and 26.9 weeks for chemotherapy. Median follow-up duration was 19.7 months (randomization to cut-off date). The study met its primary objective, with ceritinib demonstrating statistically significant improvement in BIRC PFS (RECIST 1.1; median, 16.6 [12.6, 27.2] vs 8.1 months [5.8, 11.1], HR=0.55, P<0.001) versus chemotherapy. OS was immature (HR, 0.73 [0.50, 1.08]; P=0.056) with 42.3% of required events at interim analysis. ORR (BIRC, 72.5% vs 26.7%) and DOR (BIRC, median, 23.9 vs 11.1 months) were also higher with ceritinib versus chemotherapy. Among patients with measurable baseline BM and ≥1 postbaseline assessment, intracranial ORR (BIRC neuroradiologist; modified RECIST v1.1) was higher with ceritinib (72.7% [49.8, 89.3] vs 27.3% [10.7, 50.2]) versus chemotherapy (Table). Most common AEs (>50%) with ceritinib were diarrhea (84.7%), nausea (68.8%), vomiting (66.1%), ALT increase (60.3%), and AST increase (52.9%). Overall, 5.3% ceritinib- and 11.4% chemotherapy-treated patients discontinued due to AEs suspected to be drug-related. Figure 1
First-line ceritinib achieved statistically significant and clinically meaningful improvement in median PFS with an estimated 45% risk reduction in advanced ALK+ NSCLC versus chemotherapy including maintenance. Moreover, ceritinib achieved high and durable systemic responses and high OIRR in patients with measurable BM. Safety profile of ceritinib is consistent with previously reported.
