简要总结
Larotrectinib, a selective TRK inhibitor has showed marked and durable antitumor activity in patients with NTRK gene-fusion-positive tumors regardless of the tumor type, gene partner and patient's age. Because of this and the lack of alternative therapy in this rare but severe disease, the French National Agency for Medicines and Health Products Safety (ANSM) granted in April 2019, a "cohort" Temporary Authorization for Use (ATU) in the indication:"Larotrectinib is indicated as monotherapy for the treatment of adult and paediatric patients from one month, with locally advanced or metastatic solid tumours with a Neurotrophic Tyrosine Receptor Kinase (NTRK) fusion, refractory to standard treatments or in the absence of appropriate therapeutic alternative." Despite the potential benefit of identifying these fusions, the clinicopathologic features of NTRK fusion-positive tumors which are treated with Larotrectinib, are not well characterized. This study will provide information about the diagnosis and management of patients with locally advanced or metastatic NTRK fusion cancer treated with Larotrectinib under real-world treatment conditions in France, and describes the dosing patterns, safety and effectiveness of this agent.
详细描述
Tropomyosin receptor kinases (TRK) are a family of tyrosine kinases that bind neurotrophins, a family of growth factors important to the formation and function of the nervous system. In cancer, the neurotrophic tyrosine kinase receptor (NTRK)1, NTRK2 and NTRK3 genes, which encode for the TRKA, TRKB and TRKC proteins, respectively, are subject to gene-arrangements that lead to kinase domain expression and constitutive downstream pathway activation. In preclinical models, NTRK gene fusions have transformative oncogenic potential, and they appear to be widely distributed across histologically diverse adult and pediatric cancers. Hence, these genetic abnormalities, observed in both children and adults, have recently emerged as targets for cancer therapy.
Larotrectinib, a selective TRK inhibitor has showed marked and durable antitumor activity in patients with NTRK gene-fusion-positive tumors regardless of the tumor type, gene partner and patient's age.
Because of this and the lack of alternative therapy in this rare but severe disease, the French National Agency for Medicines and Health Products Safety (ANSM) granted in April 2019, a "cohort" Temporary Authorization for Use (ATU) in the indication:
"Larotrectinib is indicated as monotherapy for the treatment of adult and paediatric patients from one month, with locally advanced or metastatic solid tumours with a Neurotrophic Tyrosine Receptor Kinase (NTRK) fusion, refractory to standard treatments or in the absence of appropriate therapeutic alternative." Despite the potential benefit of identifying these fusions, the clinicopathologic features of NTRK fusion-positive tumors which are treated with Larotrectinib, are not well characterized.
This study will provide information about the diagnosis and management of patients with locally advanced or metastatic NTRK fusion cancer treated with Larotrectinib under real-world treatment conditions in France, and describes the dosing patterns, safety and effectiveness of this agent.
