ReviewLorlatinib for the treatment of ALK-positive metastatic non-small cell lung cancer.
Introduction: The treatment of lung cancer has changed dramatically with the development of tyrosine kinase inhibitors (TKIs) that target sensitizing somatic (gene) activations including anaplastic lymphoma kinase (ALK)-rearrangements. Despite remarkable initial responses, patients develop progressive disease via various resistance mechanisms, some of which are ALK dependent. Various next-generation ALK TKIs have been developed to improve on central nervous system (CNS) activity and also target the multitude of acquired resistance mechanisms. ⋯ Expert opinion: Patients invariably develop resistance during treatment with lorlatinib. Unique combinations of ALK resistance mutations may confer sensitivity to alternate ALK TKIs. There is a move toward individualized biomarker-driven treatment strategies to identify the select group of candidates that can benefit from existing therapies.

ReviewElotuzumab in combination with pomalidomide and dexamethasone for the treatment of multiple myeloma.
Introduction: Despite major advances in the therapeutic management of multiple myeloma (MM), it remains an incurable disease. Several combinations of monoclonal antibodies with novel agents are being investigated with promising results in order to prolong progression-free and overall survival. ⋯ These regimens seem to be more effective than the standard combination of pomalidomide with dexamethasone alone. Taking into consideration that the vast majority of MM patients will receive upfront treatment including a PI and lenalidomide in the near future, pomalidomide-based triplets, such as elotuzumab-pomalidomide-dexamethasone, will become the standard of care in the second line of therapy.

Introduction: Fibroblast growth-factor receptor (FGFR) inhibition is a promising strategy of treatment in urothelial cancer (UC). FGFR3 mutations or fusions (mut/fus) are common in luminal-1 UC subtype, which exhibits poor responses to immunotherapy. Erdafitinib is a potent and selective pan-FGFR tyrosine kinase inhibitor. ⋯ Special attention must be paid to typical adverse class-effects of FGFR inhibitors. In the near future, in order to achieve an optimal selection of molecularly-altered tumors, it will be important to assess the performance of different diagnostic tools and to investigate the role of liquid biopsy. Combinations with immunotherapy represent a novel therapeutic opportunity being tested in ongoing trials.

ReviewSacituzumab govitecan: breakthrough targeted therapy for triple-negative breast cancer.
Introduction: Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype associated with an increased risk of recurrence and cancer-related death. Unlike hormone receptor-positive or HER2-positive breast cancers, there are limited targeted therapies available to treat TNBC and cytotoxic chemotherapy remains the mainstay of treatment. Sacituzumab govitecan (IMMU-132) is an antibody-drug conjugate targeting Trop-2 expressing cells and selectively delivering SN-38, an active metabolite of irinotecan. ⋯ A confirmatory Phase III randomized clinical trial is ongoing. Sacituzumab govitecan has a manageable side effect profile, with the most common adverse events being nausea, neutropenia, and diarrhea. The activity of sacituzumab govitecan likely extends beyond TNBC with promising early efficacy data in many other epithelial cancers, including hormone receptor-positive breast cancer.
