In The New England Journal of Medicine, a report revealed the distribution of KRASG12C mutations by race and sex. Researchers analyzed the prevalence of KRASG12C mutations in 32,138 patients with cancer, 13.8% of whom had NSCLC. They found that among patients with NSCLC, KRASG12C mutations occurred in 13% of white, 10.9% of Black, and 3.6% of Asian patients. This mutation was significantly more common in white and Asian women with NSCLC than their male counterparts.
The FDA approved crizotinib (Xalkori; Pfizer) in children and young adults with relapsed/refractory, systemic anaplastic large cell lymphoma who have ALK mutations. The approval was based on a phase I/II trial in which 26 patients had an objective response rate of 88% and a complete remission rate of 81%. An ALK inhibitor, crizotinib was previously approved for patients with NSCLC who have ALK or ROS1 mutations.
The FDA placed a clinical hold on Neoleukin Therapeutics’ phase I trial of NL-201. The agency asked Neoleukin to develop a new assay that more precisely measures dosing of the drug. NL-201 is a protein therapeutic that stimulates IL2 and IL15 signaling.
