ASCEND- study of Zykadia (ceritinib) successful for (ALK+) advanced non-small cell lung cancer (NSCLC).-Novartis.

Novartis announced results from its Phase III open-label, randomized, active-controlled, multi-center ASCEND-4 study, which found that patients with anaplastic lymphoma kinase-positive (ALK+) advanced non-small cell lung cancer (NSCLC) treated with first-line Zykadia (ceritinib) had a median progression-free survival (PFS) of 16.6 months (95% confidence interval [CI]: 12.6, 27.2), compared to 8.1 months (95% CI: 5.8, 11.1) in patients treated with standard first-line chemotherapy with maintenance. This equated to a 45% reduction in the risk of disease progression (hazard ratio [HR] = 0.55, P<0.001).

Results were presented during the Presidential Symposium at the 17th World Conference on Lung Cancer (WCLC), hosted by the International Association for the Study of Lung Cancer (IASLC), in Vienna. These late-breaking results were also featured in an official conference press briefing. Overall survival data, a key secondary endpoint of the study, are immature; however, a positive trend in favor of Zykadia was observed, despite 72.4% of patients in the chemotherapy arm receiving an ALK inhibitor as their first treatment after discontinuing chemotherapy. Pre-specified secondary endpoints demonstrating the efficacy of Zykadia in ALK+ advanced NSCLC patients included overall response rate (ORR), overall intracranial response rate (OIRR), disease control rate (DCR) and duration of response (DoR). Patients taking Zykadia had an ORR of 72.5% (95% CI: 65.5, 78.7) compared to 26.7% (95% CI: 20.5, 33.7) in patients treated with standard chemotherapy. Further, patients with measurable brain metastases experienced an OIRR of 72.7% (95% CI: 49.8, 89.3, n=22) with Zykadia compared to 27.3% (95% CI: 10.7, 50.2, n=22) with standard chemotherapy. Patients without brain metastases at screening experienced a median PFS of 26.3 months (95% CI: 15.4, 27.7, n=130) with Zykadia compared to 8.3 months (95% CI: 6.0, 13.7, n=125) with standard chemotherapy. Additionally, patients taking Zykadia demonstrated a DCR of 84.7% (95% CI: 78.7, 89.5) and DoR of 23.9 months (95% CI: 16.6, not estimable). Study results were measured by a blinded independent review committee (BIRC). Patients treated with Zykadia also reported better overall general health status and improvement in lung cancer-specific symptoms compared to patients treated with standard chemotherapy.
