MINI31.14 - PROs with Ceritinib in ALKi-Naive ALK+ NSCLC Patients with and without Brain Metastases (ID 1528)
19:45 - 19:50 | Author(s): J. Zhang
- Abstract
Background:
In the pivotal ASCEND-1 study, ceritinib, an anaplastic lymphoma kinase inhibitor (ALKi), demonstrated sustained clinical activity in ALKi-naive patients with ALK-rearranged (ALK+) non-small cell lung cancer (NSCLC), including in patients with brain metastases (BrM). ASCEND-3 (NCT01685138) evaluated patient-reported outcomes (PROs) as well as clinical outcomes with ceritinib, in ALKi-naive ALK+ NSCLC patients with and without baseline BrM.
Methods:
Adult patients with ALK+ NSCLC previously treated with up to 3 lines of cytotoxic therapy received oral ceritinib 750 mg daily. PROs were assessed using Lung Cancer Symptom Scale (LCSS) and EORTC (QLQ-C30, QLQ-LC13) quality of life and lung cancer surveys at baseline and Day 1 of treatment cycles 2, 3, and every two cycles thereafter (1 cycle=28 days). Data were analyzed by presence/absence of baseline BrM. Data beyond cycle 9 are not reported due to small sample sizes.
Results:
Of 124 enrolled patients (median age [range] 56 [27–82] years; 40.3% male), 50 (40.3%) had BrM at baseline. At data cutoff (27 June 2014), median follow-up was 8.3 months. Up to cycle 9, PRO questionnaire compliance was at least 97.0%. In the overall patient population, investigator-assessed disease control rate (DCR) was 89.5% and median duration of response (DOR) 9.3 months. Investigator-assessed whole-body DCR [95% confidence interval (CI)] in patients with and without baseline BrM was 86.0% [73.3, 94.2] and 91.9% [83.2, 97.0], respectively, while DOR [95% CI] was 9.1 [7.5, Not Estimable] and 10.8 [9.3, 10.8] months, respectively. Mean change from baseline in patients’ total LCSS score ranged from -3.4 to -11.4 while receiving ceritinib, with 82.1% of patients experiencing symptom improvement; symptoms improved in patients with and without baseline BrM (Figure). QLQ-LC13 outcomes were broadly consistent with those of LCSS in the full patient population and in the subgroups of patients with and without baseline BrM. In general, mean global quality of life (QLQ-C30) was maintained on treatment for all patients. Patients reported diarrhea and nausea and vomiting symptoms were worse than baseline, however, nausea and vomiting symptoms did reduce over time. Figure 1
Conclusion:
In ALKi-naive patients with ALK+ NSCLC, treatment with ceritinib demonstrated clinical efficacy and improved cancer symptoms, with health-related quality of life generally maintained regardless of baseline BrM status. Improvements were greatest for the lung-related symptoms, cough and pain.
