Where can I buy larotrectinib in China?

Larotrectinib is an innovative anti-cancer drug that belongs to the category of targeted therapy drugs. It was developed to treat cancer patients who carry NTRK (neuronal growth factor receptor kinase) gene fusions and provide personalized and precise treatment options for this specific patient subgroup.

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.

NTRK gene fusion is a rare genetic abnormality that occurs in a variety of cancers, including soft tissue sarcoma, infantile fibroma, lung cancer, and others. This gene fusion leads to out-of-control NTRK kinase activity, promotes abnormal cell proliferation and survival signaling, and promotes tumor development. Larotrectinib blocks this abnormal signaling pathway by targeting the NTRK kinase, thereby inhibiting the growth and spread of cancer cells.

The uniqueness of the drug is that it is treated based on the patient's genetic characteristics, and genetic testing is required to confirm whether the patient carries theNTRK gene fusion. This personalized treatment strategy ensures optimal drug efficacy and reduces unnecessary treatment for patients.

Larotrectinib is usually taken as an oral medication that can be administered daily in a home setting. Clinical trial results show that larotrectinib shows significant efficacy for patients carrying NTRK gene fusions, including tumor shrinkage, stopping progression, and even complete tumor disappearance in some patients.
