Is capmatinib effective for brain metastases?

Data on the efficacy of capmatinib (Capmatinib) in the treatment of brain metastases from non-small cell lung cancer (NSCLC) are relatively limited. Brain metastasis is one of the common complications in patients with NSCLC and poses a therapeutic challenge due to the unique physiology and drug penetration of brain tissue.

Some preliminary studies and clinical trials suggest that capmatinib may have some efficacy against brain metastases inNSCLC patients. Abnormal activation of METkinase in lung cancer is closely related to the formation and development of brain metastases, and capmatinib, as a drug targeting METkinase, may theoretically have a positive impact on preventing or slowing down the progression of brain metastases.

However, it should be noted that the treatment of brain metastases is often affected by multiple factors, including the size and location of the tumor, the patient's systemic condition, and cerebral vascular permeability. In addition, the presence of the blood-brain barrier may make it difficult for some drugs to penetrate into brain tissue.

Further research and large-scale clinical trial data are needed to confirm the specific efficacy of capmatinib in brain metastasis. During the treatment of brain metastases, doctors may combine other treatments, such as radiotherapy, surgery, etc., to comprehensively manage the patient's condition.

Capmatinib is not yet available in China, so patients cannot purchase it domestically yet and need to purchase it through overseas channels. Currently, there are Hong Kong version of original drugs and foreign original drugs and generic drugs. The price of Hong Kong version of original drugs is about 35,000 yuan. The overseas original drugs are mainly European version of original drugs, and the price is more than 50,000 yuan, so original drugs are still relatively expensive. Generic drugs on the market abroad are much cheaper, mainly Laos generic drugs, the price is around 3,000 to 4,000 yuan, and the ingredients of original drugs and generic drugs are basically the same.
