Larotrectinib is a kinase inhibitor used to treat solid tumors with neurotrophin receptor tyrosine kinase gene fusions that are metastatic, have a high risk of surgery, or have no alternative treatment options. Larotrectinib is an orally available tropomyosin receptor kinase (Trk) inhibitor with demonstrated antitumor activity. Following administration, larotrectinib binds to Trk, thereby preventing neurotrophin-Trk interaction and Trk activation, resulting in both induction of cellular apoptosis and inhibition of cell growth in tumors that overexpress Trk. Trk, a receptor tyrosine kinase activated by neurotrophins, is mutated in various cancer cell types and plays an important role in tumor cell growth and survival. Originally discovered by Array BioPharma, the agent was eventually licensed to Loxo Oncology in 2013. Larotrectinib is another example of innovative new cancer drugs that target key, specific genetic biomarkers that cause cancer rather than specific tumor types.
 
Larotrectinib is a tyrosine kinase inhibitor that is currently indicated for the treatment of adults and children with solid tumors that: a) have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, b) are metastatic or surgical resection would likely result in severe morbidity, c) have no satisfactory alternative treatments, or that have progressed following treatment.
Larotrectinib acts as a TRK inhibitor, including TRKA, B and C. In vitro and in vivo tumor models, larotrectinib demonstrated antitumor activity in cells with constitutive activation of TRK proteins due to gene fusion, deletion of the protein regulatory domain, or in cells overexpressing the TRK protein. Larotrectinib had minimal activity in cell lines with point mutations in the TRKA kinase domain, including the clinically identified acquired resistance mutation, G595R. Point mutations in the TRKC kinase domain with clinically identified acquired resistance to larotrectinib include G623R, G696A, and F617L.
