Many repotrectinib AEs, including neurological AEs secondary to TRK inhibition, were mitigated with appropriate management, including dose modification and/or pharmacologic intervention.

Peripheral monocyte profiling of the patient post-Repotrectinib and localized radiotherapy showed 75% CD8+/CD3 + T cells, 14.2% CD4+/CD3 + T cells, 3.95% regulatory T cells (Tregs), and 38% PD-1 + CD3 + T cells...Furthermore, we also provide a comprehensive review of recent clinical advancements in ALK/ROS1-TKI for NSCLC, including mechanistic insights into TKI resistance development. This case underscores the therapeutic potential of molecular-targeted agents in LUSC and highlights the essential role of NGS-guided precision oncology.
The best TRK inhibitor 5c had IC50 values of 0.75 and 0.96 nM against TRKAG595R and TRKAG667C, showing better potency than drugs larotrectinib (approximately 87- and 46-fold improvement) and selitrectinib (approximately 10- and 13-fold improvement). More importantly, 5c demonstrated favorable in vivo pharmacokinetic properties and antitumor efficacy (tumor growth inhibition (TGI) of 91% at 30 mg/kg and 115% at 60 mg/kg with 4 of 6 partial regression) in a BaF3-TMP3-TRKAG667C xenograft mouse model, which is greatly superior to that of selitrectinib (TGI of 2% at 30 mg/kg). Compound 5c exhibits significant potential to overcome clinical acquired multiple resistance to TRK inhibitors.
Repotrectinib is not cost-effective at current prices, but first-line use is consistently more economically favorable than second-line therapy. Price reductions or shorter treatment durations could improve its cost-effectiveness.
