厄达替尼的副作用与注意事项

Erdafitinib is a targeted therapy drug targeting FGFR gene mutations and has shown significant effects in the treatment of locally advanced or metastatic urothelial cancer. This article will introduce in detail the side effects, usage precautions and treatment effects of this drug. Erdafitinib may cause a variety of adverse reactions, including eye disease and hyperphosphatemia.

Side effects of erdafitinib

Erdafitinib may cause a variety of adverse reactions during treatment, and the incidence and severity of these side effects vary from person to person. Prompt recognition and management of side effects is critical to maintaining treatment effectiveness.

Common adverse reactions

Patients will experience symptoms such as elevated phosphate, nail lesions, and stomatitis. Gastrointestinal reactions such as diarrhea, constipation, and loss of appetite are also common. Laboratory tests often show abnormalities such as elevated creatinine and elevated alkaline phosphatase.

Eye-related side effects

Central serous retinopathy/retinal pigment epithelial detachment (CSR/RPED) is a serious adverse reaction that requires special attention. Patients may experience symptoms such as blurred vision and visual field defects. Dry eye is also a common symptom and requires preventive treatment.

Skin and metabolic abnormalities

Dry skin, palmoplantar erythrodysesthesia syndrome and alopecia are typical skin reactions. Metabolically, the main manifestations are hyperphosphatemia, which can lead to soft tissue mineralization in severe cases.

Understanding these side effects can help patients identify and take countermeasures in time, and seek medical help if necessary.

Precautions for erdafitinib

Using erdafitinib requires following a number of precautions. These measures can effectively reduce treatment risks and improve drug safety.

Eye monitoring requirements

Eye examinations are required monthly for the first 4 months of treatment and every 3 months thereafter. Examination should include visual acuity assessment, slit lamp examination, and optical coherence tomography. If you develop vision symptoms, seek medical attention immediately.

Hyperphosphatemia management

It is recommended to limit daily phosphate intake to 600-800mg. When serum phosphate is higher than 7.0 mg/dL, oral phosphate binders should be considered. Periodic monitoring of serum phosphate levels is critical for dose adjustment.

Drug interactions

Avoid coadministration with strong inducers or inhibitors of CYP3A4, which may affect drug metabolism. Also note that drugs that may alter serum phosphate levels may interfere with dose adjustment.

Strictly adhering to these precautions can minimize the risks of treatment.

The efficacy of erdafitinib

As an FGFR inhibitor, erdafitinib has shown significant therapeutic effects in specific patient groups. Understanding its efficacy characteristics can help patients build confidence in treatment.

Effects of targeted therapy

Erdafitinib selectively inhibits FGFR1-4 and has a significant inhibitory effect on tumors carrying FGFR2/3 mutations or fusions. This targeted mechanism of action makes it effective in specific patients.

Clinical research data

Pivotal clinical trials show that erdafitinib exhibits durable anti-tumor activity in patients with previously treated FGFR-mutated urothelial carcinoma. Both the objective response rate and disease control rate reached clinically meaningful levels.

Advantages of personalized medication

The dose adjustment strategy based on serum phosphate levels enables individualization of treatment. This dynamic adjustment method not only ensures the efficacy but also reduces the risk of adverse reactions as much as possible.

Erdafitinib provides a new treatment option for patients with FGFR mutations, and its targeted and personalized characteristics represent the development direction of precision medicine.
