Erdafitinib, sold under the brand name Balversa, is a medication used to treat urothelial cancer.[2] Specifically it is used for cases which have suitable FGFR-2 or 3 mutations.[2] It is taken by mouth.[2]

Common side effects include high phosphate, mouth inflammation, tiredness, kidney problems, diarrhea, liver problems, change in taste, low magnesium, hair loss, high calcium, and muscle pain.[2] Other side effects may include infertility and vision problems.[2] Use in pregnancy may harm the baby.[2] It is a tyrosine kinase inhibitor, specifically a fibroblast growth factor receptor (FGFR) blocker.[1][2]

Erdafitinib was approved for medical use in the United States in 2019.[2] It is not approved for use in the United Kingdom or Europe as of 2021.[1] In the United States 4 weeks of treatment costs about 21,500 USD as of 2021.[3]

Medical uses

Dosage

Erdafitinib is a tablet taken once a day for a total dose of 8 mg. During treatment, the erdafitinib dose may be increased to 9 mg if needed.[4]

Side effects

Common side effects include 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.[5] Other side effects include redness, swelling, peeling or tenderness on the hands or feet (hand foot syndrome), constipation, stomach pain, nausea and muscle pain.[5]

Erdafitinib 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.[5] 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.[5]

History

The efficacy of erdafitinib was studied in a clinical trial (NCT02365597) that included 87 adults with locally advanced or metastatic bladder cancer, with FGFR3 or FGFR2 genetic alterations, that had progressed following treatment with chemotherapy.[5][4] The overall response rate in these adults was 32.2%, with 2.3% having a complete response and almost 30% having a partial response.[5] The response lasted for an average of approximately five-and-a-half months.[5] The trial was conducted in Asia, Europe, and the United States.[4]

Erdafitinib received an accelerated approval.[5] Further clinical trials are required to confirm erdafitinib's clinical benefit and the sponsor is conducting or plans to conduct these studies.[5] Erdafitinib was also granted breakthrough therapy designation.[5]

The FDA granted the approval of Balversa to Janssen Pharmaceutical.[5] The FDA also approved the therascreen FGFR RGQ RT-PCR Kit, developed by Qiagen Manchester, Ltd., for use as a companion diagnostic with Balversa for this therapeutic indication.[5]

History

Researchers have investigated erdafitinib for safety and efficacy in treatment of bile duct cancer, gastric cancer, non-small cell lung cancer, and esophageal cancer.[6]

In March 2018, erdafitinib was granted breakthrough therapy designation by the U.S. Food and Drug Administration (FDA) for treatment of urothelial cancer.[7]

In April 2019, erdafitinib was granted approval by the FDA for treatment of metastatic or locally advanced bladder cancer with an FGFR3 or FGFR2 alteration that has progressed beyond traditional platinum-based therapies, subject to a confirmatory trial.[5][8] The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.[9]
