How much does a box of larotrectinib cost in 2024?

Larotrectinib is a new type of targeted therapy drug that belongs to a class of tyrosine kinase inhibitors. It is primarily used to treat tumors in adult and pediatric patients that carry NTRK gene fusions. NTRKGene fusion is a rare but genetic abnormality found in a variety of cancers, including solid tumors such as soft tissue sarcoma, infantile fibroma, lung cancer, etc.

Larotrectinib has been launched in China and has not yet been included in medical insurance. Since it has not been launched in China for a long time, it may be difficult to purchase it in hospitals. For specific conditions, it is recommended to consult the local hospital pharmacy. In foreign markets, larotinib has two options: original drug and generic drug. Original drugs include the German version, the American version, the European version and the Hong Kong version, and the price is about 10,000 to 20,000 yuan. In comparison, generic drugs are much cheaper. There are Lao and Bangladeshi versions of generic drugs, and the price is around two to three thousand. It is worth noting that the ingredients of original drugs and generic drugs are basically the same.

Larotrectinib is unique in that it is highly selective forNTRK gene fusions. This fusion renders NTRK kinase independent of normal regulatory mechanisms, leading to abnormal cell proliferation and survival signaling, thereby promoting tumor development. By inhibiting the activity of NTRK kinase, larotrectinib can block these abnormal signaling pathways, thereby inhibiting tumor growth.

Clinical trial results show that larotrectinib has achieved significant efficacy in NTRK gene fusion-positive tumor patients. Patients may experience tumors shrinking, stopping progression, or even disappearing completely. In addition, the safety of larotrectinib has also been strictly evaluated. Common adverse reactions mainly include mild side effects such as fatigue, dizziness, and nausea.
