What drug should be used after Lorlatinib resistance?

Lorlatinib is a drug that targets ALK (tyrosine kinase) and ROS1 (NSCLC) with mutations in an>ROS1kinase have shown significant efficacy during treatment, the development of drug resistance is still a possible problem. When a patient develops resistance to lorlatinib, doctors may consider adjusting the treatment regimen and selecting other appropriate drugs. Here are some alternative treatments that may be considered after drug resistance:

1. Next generationALK inhibitors: For ALK positive NSCLC patients, next generation ALK inhibition Agents, such as alectinib (alectinib), ceritinib (ceritinib) and endotinib (brigatinib), may be considered as alternative treatment options. These drugs have different molecular structures and mechanisms of action that can help overcome the development of drug resistance.

2. ROS1Inhibitors: For ROS1positive NSCLC patients, otherROS1Inhibitors, such as crizotinib (crizotinib), rogefenib (lorlatinib), etc., may become alternatives. These drugs act on different molecular targets and help maintain effective suppression of ROS1 mutations.

3. Chemotherapy and immunotherapy: In some cases, doctors may consider using chemotherapy drugs, such as cisplatin, paclitaxel, etc., or immunotherapy, such as PD-1/PD-L1 inhibitors, to combat drug resistance. The choice of these treatment modalities may depend on the patient's overall health and the specific characteristics of the disease.

In treatment decisions after drug resistance, doctors usually conduct a comprehensive evaluation based on the patient's specific situation, pathological characteristics and molecular data. Treatment options are chosen to maximize patient survival and improve quality of life. When patients face drug resistance, they should actively communicate with their doctors, jointly develop appropriate treatment strategies, and participate in possible treatment plans under the guidance of their doctors.

Lorlatinib has been launched in China and is included in medical insurance. Patients can purchase it domestically, but the price is relatively high, about 10,000 to 20,000 yuan. Please consult the local hospital pharmacy for details. There are original lorlatinib drugs and cheaper generic drugs abroad. The cheaper ones are the original drug from Turkey, which costs more than 1,000 yuan, and the original drug from Hong Kong, China, which costs about 30,000 yuan. Generic drugs are mainly generic drugs from Laos and Bangladesh. The price is about several thousand yuan, and the ingredients of the original drugs and generic drugs are basically the same.
