ALK-Rearranged Non-Small Cell Lung Cancer in 2020: Real-World Triumphs in an Era of Multigeneration ALK-Inhibitor Sequencing Informed by Drug Resistance Profiling.

Since its discovery in 2007, we have seen the lives of patients diagnosed with advanced anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancers (NSCLC) transform with the advent of molecular therapies with first-, second-, and third-generation ALK inhibitors now available in the clinic. Despite great gains in patient survival now measured in years and preserved quality of life with targeted therapies, drug resistance is unfortunately inevitably encountered in this rare and unique molecular subset of lung cancer, and patients will eventually succumb to the disease. As these patients are often young, fit, and never smokers, the clinical and scientific communities have aligned to expedite drug development and access.

Tolerance and efficacy of BRAF plus MEK inhibition in patients with melanoma who previously have received programmed cell death protein 1-based therapy.

Background: Combined BRAF and MEK inhibition (BRAF-MEK) is a standard therapy for patients with BRAF V600-mutant melanoma, but to the authors' knowledge, the tolerance, adverse event (AE) profile, and efficacy have not been well defined in the post-programmed cell death protein 1 (PD-1) setting.

Methods: Patients with BRAF V600-mutant melanoma who received combined BRAF-MEK after prior PD-1-based therapy were assembled from 4 tertiary care centers in the United States and Australia. Dose modification was defined as a treatment break, dose reduction, or intermittent dosing.
