FDA原文：
The U.S. Food and Drug Administration granted accelerated approval to Balversa (erdafitinib), a treatment for adult patients with locally advanced or metastatic bladder cancer that has a type of susceptible genetic alteration known as FGFR3 or FGFR2, and that has progressed during or following prior platinum-containing chemotherapy. Patients should be selected for therapy with Balversa using an FDA-approved companion diagnostic device.
Common side effects reported by patients taking Balversa were increased phosphate level, mouth sores, feeling tired, change in kidney function, diarrhea, dry mouth, nails separating from the bed or poor formation of the nail, change in liver function, low salt (sodium) levels, decreased appetite, change in sense of taste, low red blood cells (anemia), dry skin, dry eyes and hair loss. Other side effects include redness, swelling, peeling or tenderness on the hands or feet (hand foot syndrome), constipation, stomach pain, nausea and muscle pain.
Balversa may cause serious eye problems, including inflamed eyes, inflamed cornea (front part of the eye) and disorders of the retina, an internal part of the eye. Patients are advised to have eye examinations intermittently and to tell their health care professional right away if they develop blurred vision, loss of vision or other visual changes. Health care professionals are advised to check patients’ blood phosphate level between 14 and 21 days after starting treatment and monthly, and to increase the dose Balversa in patients whose serum phosphate is below the target level.
Health care professionals are advised to tell male patients with female partners of reproductive potential to use effective contraception during treatment with Balversa and for one month after the last dose. Pregnancy testing is recommended for females of reproductive potential prior to initiating treatment with Balversa. Women who are pregnant or breastfeeding should not take Balversa because it may cause harm to a developing fetus or newborn baby. Balversa must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.
