Zongatinib (Zongatinib) dosage and clinical medication regimens for different patients

Zongertinib (zongertinib) is an oral, small-molecule tyrosine kinase inhibitor targeted for patients with non-small cell lung cancer (NSCLC) and other solid tumors harboring specific RET mutations or fusions. Its mechanism of action is by selectively inhibiting RET kinase activity and blocking downstream signaling pathways, thereby inhibiting tumor cell proliferation and promoting apoptosis. In clinical application, the medication regimen needs to be individually adjusted based on the patient's mutation type, weight, liver and kidney function, and previous treatment.

For adult treatment-naive patients or patients who have previously received standard treatment but have not tolerated chemotherapy, the conventionally recommended dose is once daily, with the specific dose usually ranging from 80 mg to 160 mg, depending on the patient's weight and tolerance. The medication should be taken at a fixed time to avoid missing doses. At the same time, attention should be paid to the simultaneous use of drugs that may affect drug metabolism, such as CYP3A4 inhibitors or inducers, to prevent abnormal increases or decreases in blood drug concentration, thereby affecting efficacy and safety.

Zongatinib dose adjustments vary across patient populations. For patients with impaired hepatic function or mild to moderate abnormalities in renal function, dose reduction or dosing intervals may need to be extended to reduce the risk of adverse events. For older or weaker patients, it is also clinically recommended to start with a low dose and gradually increase to the standard dose, while closely monitoring hematological indicators, liver function and electrocardiogram changes to ensure tolerance.
During long-term treatment, doctors usually make dynamic adjustments to the medication regimen based on imaging evaluation, symptom changes, and laboratory indicators. For example, if a patient experiences significant liver enzyme elevations, abnormal blood pressure, or other controllable side effects, the drug can be temporarily discontinued or the dose can be reduced before returning to the standard dose. In addition, for patients with obvious efficacy and good tolerance, the standard dose can be continued until disease progression or intolerable side effects occur. Overall, zongatinib's medication regimen emphasizes individualization, precision, and continuous monitoring to achieve optimal efficacy and safety.
