“The FDA approved use of dabrafenib in combination with trametinib for treatment of patients with metastatic non–small cell lung cancer whose tumors harbor BRAF V600E mutations, according to the agents’ manufacturer.
“The combination of dabrafenib (Tafinlar, Novartis) — a BRAF inhibitor — and trametinib (Mekinist, Novartis), a MEK1/2 inhibitor — is the first targeted treatment approved in the United States specifically for patients with BRAF V600E–positive metastatic NSCLC.”
“Findings from a phase III clinical trial for advanced lung cancer patients could help oncologists better predict which patients are likely to receive the most benefit from immunotherapy as a first-line treatment based on the unique molecular characteristics of their tumor, according to a new study reported by a global team led by David Carbone, MD, PhD, of The Ohio State University Comprehensive Cancer – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“In this study, researchers compared the effectiveness of the immunotherapy drug nivolumab (pronounced ‘nye VOL ue mab,’ marketed at Opdivo), with standard-of-care chemotherapy in 541 patients with previously untreated or recurrent non-small cell lung cancer (NSCLC) that expressed PDL-1 antibodies.”
“The antibody-drug conjugate sacituzumab govitecan (IMMU-132) was well-tolerated and produced a median duration of response of 6.0 months in previously treated patients with metastatic non–small cell lung cancer (NSCLC), according to results from a single-arm, multicenter trial.
“The results, which were published online in the Journal of Clinical Oncology, showed a median progression-free survival of 5.2 months (95% CI, 3.2-7.1) and median overall survival of 9.5 months (95% CI, 5.9-16.7) in the intent-to-treat population. The clinical benefit rate of 43%.”
“Adding palifosfamide to carboplatin and etoposide failed to improve survival over the latter two agents alone in patients with extensive stage (ES) small-cell lung cancer (SCLC), according to a new study.
” ‘Platinum doublet chemotherapy has been the standard of care first-line regimen in patients with ES SCLC for the last 3 decades,’ wrote study authors led by Shadia I. Jalal, MD, of the Indiana University Melvin and Bren Simon Cancer Center in Indianapolis. ‘Unfortunately, disease relapse occurs in all patients, and second-line chemotherapy options lead to short responses. Novel first-line therapies continue to be urgently needed.’ ”
“Treatment with nintedanib plus pemetrexed and cisplatin improved progression-free survival (PFS) in the frontline setting by 3.7 months for chemotherapy-naive patients with malignant pleural mesothelioma (MPM), according to data reported at the 2017 ASCO Annual Meeting.
“In the phase II trial, known as LUME-Meso, the median PFS was 9.4 months with the nintedanib combination versus 5.7 months with pemetrexed and cisplatin alone (HR, 0.54; 95% CI, 0.33-0.87; P = .010). The median overall survival (OS) was 18.3 months with nintedanib versus 14.2 months with chemotherapy alone; however, this finding was not statistically significant (HR, 0.77; 95% CI, 0.46-1.29; P = .319).”
“Immunotherapy may represent an effective new treatment approach for relapsed mesothelioma patients, according to a new study.
“Anti–programmed death-1 (PD-1) immunotherapy may have activity as second- or third-line therapy in malignant pleural mesothelioma (MPM), an aggressive, rare cancer associated with asbestos exposure that has no curative treatment. All MPM patients relapse despite initial chemotherapy, and median overall survival (OS) is 9 months at most, said lead author Arnaud Scherpereel, MD, PhD, head of the pulmonary and thoracic oncology department at the University Hospital (CHU) of Lille in Lille, France, at a press briefing at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting (abstract LBA8507).”
“Lorlatinib exhibits durable responses in pretreated patients with ALK-positive non–small-cell lung cancer (NSCLC) and promising intracranial activity and tumor responses in those patients who have brain metastases, regardless of prior therapy, according to findings from a phase I/II clinical study (abstract 9006) presented at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting, held June 2–6 in Chicago.
” ‘Lorlatinib demonstrated clinically meaningful and durable responses in ALK-positive patients receiving one or more prior ALK TKI [tyrosine kinase inhibitor], many of whom were heavily pretreated,’ said coauthor Sai-Hong Ignatius Ou, MD, of the University of California Irvine Chao Family Comprehensive Cancer Center in Orange, California.”
“AstraZeneca has presented new data showing that Tagrisso also extends progression-free survival for non-small cell lung cancer (NSCLC) patients who have central nervous system (CNS) metastases.
“According to findings from the AURA3 trial, patients with locally advanced or metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive NSCLC given the drug lived without disease worsening or death for 11.7 months compared to 5.6 months for those receiving chemotherapy.”
“Findings from a phase III clinical trial point to a more effective initial treatment for patients with ALK-positive non-small cell lung cancer (NSCLC). Compared to the current standard of care crizotinib (Xalkori), the newer ALK inhibitor alectinib (Alecensa) halted cancer growth for a median of 15 months longer and caused fewer severe side effects.
“The study will be featured in a press briefing today and presented at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting.”
