The Challenge and Opportunity of NTRK Inhibitors in Non-Small Cell Lung Cancer

Abstract: With the development of targeted therapy, non-small cell lung cancer (NSCLC) patients could have more treatment choices if target mutation presents. The neurotrophic tropomyosin receptor kinase (NTRK) has a low prevalence in NSCLC, roughly around 0.5%. FDA had approved two first generation NTRK inhibitors, larotrectinib and entrectinib. Both medications have excellent CNS penetration. This manuscript will review available data on targeting NTRK fusions in NSCLC and mechanisms of drug resistance.

“…Circumvention of these issues followed suit by using strategies such as irreversible inhibition to overcome drug resistance and the introduction of chirality to improve selectivity and efficacy profiles. [84][85][86][87] Clinical limitations to these methods were quickly realized [88][89][90] and the development of small-molecule kinase macrocycles has emerged as an innovative approach to supplement drug development efforts in the kinome (Table 9).…”

“…The key distinction between them is their ability to penetrate the CNS, with entrectinib being more effective at crossing the blood鈥抌rain barrier 150 . This has been demonstrated in its successful treatment of patients with brain metastases.…”

“…Ongoing studies seek to evaluate the efficacy and safety of the second-generation agents selitrectinib and repotrectinib, TRK inhibitors that may be able to overcome on-target treatment resistance caused by mutation of the TRK kinase domain itself [ 55 , 56 , 57 ].…”
