The FDA has granted crizotinib (Xalkori) a breakthrough therapy designation for the treatment of patients with metastatic non–small cell lung cancer (NSCLC) with MET exon 14 alterations who progress after receiving platinum-based chemotherapy. The agency also granted the designation to the kinase inhibitor for use in patients with relapsed/refractory ALK+ anaplastic large cell lymphoma (ALCL).
The most frequently reported all-grade AE in the ALCL groups was a decrease in neutrophil count, which occurred in 33% of patients receiving the lower dose and 70% of patients receiving the higher dose.
