Detailed explanation of one-year treatment cost of neratinib/neratinib

Neratinib/Neratinib, as a highly efficient HER2 tyrosine kinase inhibitor (TKI), has demonstrated significant efficacy in the anti-cancer field. It can not only assist in the treatment of breast cancer, but is also expected to play an important role in reducing the risk of brain recurrence, providing more treatment options and potential survival advantages for patients with breast cancer and brain metastases.

The common tablet strength of neratinib is40 mg. For adjuvant treatment of early-stage breast cancer, the recommended dose of neratinib is 240 mg per day, i.e., 6 tablets, each containing 40 mg of neratinib. It is usually recommended to take it with food, and the entire course of treatment is recommended to last for one year. Patients should begin treatment with neratinib within one year of completing trastuzumab. For the treatment of advanced or metastatic breast cancer, the dose of neratinib is also 240 mg daily for days 1 to 21 of a 21-day cycle.

The current packaging specification of neratinib on the market is 40 mg*180 tablets per boxThis means that one box of the drug can be used by patients for approximately one month. Therefore, if a patient requires continuous use for one year, a rough estimate would require about 12 boxes of medication.

In China, the original drug neratinib, which is already on the market and included in medical insurance, costs about RMB 7,000 per box. Therefore, the cost for patients to use it for one year may be as high as hundreds of thousands of yuan, which is a heavy financial burden for many patients. However, generic drugs of neratinib are also sold in overseas markets, and their drug ingredients are basically the same as the original drug. For example, the price of each box of neratinib produced by Bangladesh Yaopin International may be more than 2,000 yuan (the price may fluctuate due to the exchange rate). This means that the cost for patients to use it for one year may be around tens of thousands of yuan, which is relatively economical.
