How Larotrectinib works

The main efficacy of Larotrectinib (Larotrectinib) is to target TRK (neuronal growth factor receptor) gene fusion-positive tumors, specifically including the following effects:

1.Inhibiting tumor growth: Larotrectinib is a targeted therapy drug that specifically targetsTRK gene fusion. TRKGene fusion is a cancer-related genetic abnormality that can lead to abnormal proliferation and growth of tumor cells. Larotrectinib interferes with abnormal signaling by inhibiting the activity of TRK protein, thereby effectively inhibiting tumor growth.

2.Improved survival: For patients with TRK gene fusion-positive tumors, larotrectinib may significantly improve survival. By controlling tumor growth and spread, the drug has the potential to extend patients' survival.

3.Reducing symptoms: The use of larotrectinib can reduce tumor-related symptoms, such as pain, pressure, dyspnea, etc., thereby improving the patient's quality of life.

4.Personalized treatment: larotrectinib treatment is highly personalized and requires TRK gene fusion testing to determine whether the tumor is TRK gene fusion positive. This means patients can receive more precise treatment with less damage to healthy tissue.

5.Possible tumor shrinkage or stabilization: In some patients, the use of larotrectinib can cause tumor shrinkage or stabilization, so that the tumor does not progress. This is an important benefit for patients in providing disease control and improvement.

Larotrectinib has been launched in China, but it has not 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 China. Please consult the local hospital pharmacy for details. There are original drugs and generic drugs of larotrectinib abroad. The original drugs include German version, American version, European version and Hong Kong version. The price is basically around 20,000 yuan. Generic drugs include Lao and Bangladeshi versions, with prices ranging from two to three thousand. The ingredients of original drugs and generic drugs are basically the same.
