What are the side effects of lorlatinib/lorlatinib?

Lorlatinib/lorlatinib (Lorlatinib) is a second- or third-line treatment for ALK-positive metastatic non-small cell lung cancer (NSCLC). It has been approved in the United States, Europe, China and other places. It is currently the only ALK inhibitor with significant activity against the ALK G1202R mutation in lung cancer. However, there are some adverse reactions and side effects associated with the use of lorlatinib. According to the results of clinical studies, the most common adverse reactions include edema, peripheral neuropathy, weight gain, cognitive effects, fatigue, dyspnea, joint pain, diarrhea, mood effects, etc.

Some laboratory tests also show elevated cholesterol and triglyceride levels. It should be noted that concomitant use with strong CYP3A inducers (i.e. activators) may increase the risk of hepatotoxicity, so concurrent use should be avoided. In addition, there are other risks and precautions associated with using lorlatinib. These include severe hepatotoxicity, central nervous system effects, hyperlipidemia, atrioventricular block, interstitial lung disease/pneumonitis, hypertension, hyperglycemia, etc. If serious side effects occur, the dose may need to be reduced or lorlatinib discontinued.

According to study data, approximately23% of patients required dose reduction, and 3% of patients ultimately chose to discontinue lorlatinib treatment. This shows that although lorlatinib has shown good efficacy in the treatment of ALK-positive metastatic non-small cell lung cancer, its adverse reactions and side effects also require the attention and vigilance of doctors and patients.

Overall, lorlatinib is a promising drug that can be effective in the treatment of ALK-positive metastatic non-small cell lung cancer. However, it is necessary to closely monitor the patient's reaction and side effects during use, and take appropriate measures in a timely manner to ensure the safety and effectiveness of the treatment. Please consult a professional doctor before using this drug and follow your doctor's recommendations for treatment.
