| NTRK2 fusion | Advanced Solid Tumor | sensitive | Larotrectinib | Clinical Study - Cohort | Actionable | In a combined analysis of three trials, Vitrakvi (larotrectinib) resulted in improved median overall survival (39.7 vs 10.2 months) and a 78% lower risk of death (HR=0.22, P=0.001) compared to standard of care treatment in patients with advanced solid tumors harboring NTRK fusions (PMID: 36689698; NCT02122913, NCT02637687, and NCT02576431). | 36689698 |
| NTRK2 fusion | Advanced Solid Tumor | sensitive | Larotrectinib | Phase Ib/II | Actionable | In a Phase I/II trial, Vitrakvi (larotrectinib) treatment resulted in complete response in 26.7% (4/15), partial response in 66.7% (10/15), and stable disease in 6.7% (1/15) of pediatric patients with advanced solid tumors harboring NTRK fusions, and progressive diseases in all 7 patients without NTRK fusions (PMID: 29606586; NCT02637687). | 29606586 |
| NTRK2 fusion | Advanced Solid Tumor | sensitive | Larotrectinib | FDA approved | Actionable | In three trials that supported FDA approval, Vitrakvi (larotrectinib) treatment resulted in an overall response rate of 75% (41/55) in adult and pediatric patients with advanced solid tumors harboring either an NTRK1, NTRK2, or NTRK3 fusion, including 7 patients achieving a complete response and 34 patients achieving a partial response (PMID: 29466156; NCT02122913, NCT02637687, NCT02576431). | detail... 29466156 |
