Study Finds Cabozantinib Alone or With Erlotinib Improves Outcome in EGFR Wild-Type NSCLC

Excerpt:

“Treatment with the multikinase inhibitor cabozantinib (Cabometyx) alone or with erlotinib (Tarceva) improved progression-free survival vs erlotinib alone in second- or third-line treatment of advanced nonsquamous epidermal growth factor receptor (EGFR) wild-type non–small cell lung cancer (NSCLC), according to the phase II ECOG-ACRIN 1512 trial reported by Neal et al in The Lancet Oncology.”

Addition of Bevacizumab Shows No Survival Advantage Over Cisplatin Pemetrexed Alone in Non-Squamous NSCLC

Excerpt:

“Preliminary data from the SAKK19/09 trial shows no overall survival difference between two cohorts of patients with non-squamous non-small cell lung cancer (NSCLC) receiving similar cisplatin pemetrexed-based regimens.

“The SAKK19/09 trial examined a total of 77 patients with EGFR wild type non-squamous NSCLC. Both cohorts received cisplatin pemetrexed in the frontline, while one cohort had the addition of bevacizumab. In an interview with Targeted Oncology, Oliver Gautschi, MD, Assistant Professor, University of Bern, President, SAKK Lung Cancer Group, discusses the lack of differences in overall survival, where the field is going as a whole, and why combination maintenance therapy is not better than a single agent.”

Exelixis Announces Positive Results from Phase 2 Trial of Cabozantinib in Patients with EGFR Wild-Type Non-Small Cell Lung Cancer

“Exelixis, Inc. EXEL, +9.21% today announced positive results from a phase 2 clinical study evaluating cabozantinib as a treatment for EGFR wild-type non-small cell lung cancer (NSCLC). The trial, Study E1512, is a randomized phase 2 trial by the ECOG-ACRIN Cancer Research Group of cabozantinib and erlotinib, alone or in combination, as second- or third-line therapy in patients with metastatic EGFR wild-type NSCLC. Exelixis previously announced positive top-line results from this trial in November 2014. Data from the trial will be presented today during an oral presentation (Abstract #8003) at the 2015 Annual Meeting of the American Society of Clinical Oncology (ASCO), which is being held this week in Chicago, Illinois. Study chair Joel Neal, M.D., Ph.D., of ECOG-ACRIN’s Thoracic Cancer Committee and an Assistant Professor of Medicine (Oncology) at Stanford University/Stanford Cancer Institute will present the results.

“Study E1512 met its primary endpoint, demonstrating significant increases in progression-free survival (PFS) for cabozantinib and the combination of cabozantinib plus erlotinib when individually compared to the erlotinib arm. The median PFS for the combination of cabozantinib and erlotinib was 4.7 months versus 1.9 months for erlotinib alone, a more than two-fold increase that corresponds to a 65% reduction in the risk of disease worsening (hazard ratio [HR]=0.35, 80% CI 0.23-0.52, p=0.0005). The median PFS for cabozantinib monotherapy was 4.2 months versus 1.9 months for erlotinib alone, a more than doubling that corresponds to a 62% reduction in the risk of disease worsening (HR=0.38, 80% CI 0.27-0.55, p=0.0004).”
