Erdanat 4 Tablet

Erdafitinib is indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma (mUC) with susceptible FGFR3 genetic alterations whose disease has progressed on or after at least one line of prior systemic therapy. Select patients for therapy based on an FDA-approved companion diagnostic for Erdafitinib. Erdafitinib is a kinase inhibitor indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma (mUC) with susceptible FGFR3 genetic alterations whose disease has progressed on or after at least one line of prior systemic therapy. Limitations of Use Erdafitinib is not recommended for the treatment of patients who are eligible for and have not received prior PD-1 or PD-L1 inhibitor therapy.

Ocular disorders: Erdafitinib can cause central serous retinopathy/retinal pigment epithelial detachment (CSR/RPED). Perform monthly ophthalmological examinations during the first four months of treatment, every 3 months afterwards, and at any time for visual symptoms. Withhold Erdafitinib when CSR/RPED occurs and permanently discontinue if it does not resolve within 4 weeks or if Grade 4 in severity. Hyperphosphatemia: Increases in phosphate levels are a pharmacodynamic effect of Erdafitinib. Monitor for hyperphosphatemia and manage with dose modifications when required. Embryo-fetal toxicity: Can cause fetal harm. Advise patients of the potential risk to the fetus and to use effective contraception Ocular Disorders Erdafitinib can cause ocular disorders, including central serous retinopathy/retinal pigment epithelial detachment (CSR/RPED) resulting in visual field defect. In the pooled safety population, CSR/RPED occurred in 22% of patients treated with Erdafitinib, with a median time to first onset of 46 days. In 104 patients with CSR, 40% required dose interruptions and 56% required dose reductions; 2.9% of Erdafitinib-treated patients required permanent discontinuation for CSR. Of the 24 patients who restarted Erdafitinib after dose interruption with or without dose reduction, 67% had recurrence and/or worsening of CSR after restarting. CSR was ongoing in 41% of the 104 patients at the time of last evaluation. Dry eye symptoms occurred in 26% of Erdafitinib-treated patients. All patients should receive dry eye prophylaxis with ocular demulcents as needed. Perform monthly ophthalmological examinations during the first 4 months of treatment and every 3 months afterwards, and urgently at any time for visual symptoms. Ophthalmological examination should include assessment of visual acuity, slit lamp examination, fundoscopy, and optical coherence tomography. Withhold or permanently discontinue Erdafitinib based on severity and/or ophthalmology exam findings. Hyperphosphatemia and Soft Tissue Mineralization Erdafitinib can cause hyperphosphatemia leading to soft tissue mineralization, cutaneous calcinosis, non-uremic calciphylaxis and vascular calcification. Increases in phosphate levels are a pharmacodynamic effect of Erdafitinib. In the pooled safety population, increased phosphate occurred in 73% of Erdafitinib-treated patients. The median onset time of increased phosphate was 16 days (range: 8–421) after initiating Erdafitinib. Twenty-four percent of patients received phosphate binders during treatment with Erdafitinib. Vascular calcification was observed in 0.2% of patients treated with Erdafitinib. Monitor for hyperphosphatemia throughout treatment. Restrict dietary phosphate intake (600–800 mg daily) and avoid concomitant use of agents that may increase serum phosphate levels. Abridged from the full prescribing information.

The following serious adverse reactions are also described elsewhere in the labeling: Ocular Disorders. Hyperphosphatemia. The most common (>20%) adverse reactions, including laboratory abnormalities, were increased phosphate, nail disorders, stomatitis, diarrhea, increased creatinine, increased alkaline phosphatase, increased alanine aminotransferase, decreased hemoglobin, decreased sodium, increased aspartate aminotransferase, fatigue, dry mouth, dry skin, decreased phosphate, decreased appetite, dysgeusia, constipation, increased calcium, dry eye, palmar-plantar erythrodysesthesia syndrome, increased potassium, alopecia, and central serous retinopathy. at ( and www.Erdafitinib.com) or FDA Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The pooled safety population described in the WARNINGS AND PRECAUTIONS reflects exposure to Erdafitinib as a single agent at the recommended dose (8 to 9 mg orally daily) in 479 patients with advanced urothelial cancer and FGFR alterations in 42756493BLC3001 (NCT03390504), 42756493BLC2001 (NCT02365597), 42756493BLC2002 (NCT 03473743), and 42756493EDI1001 (NCT01703481). Among 479 patients who received Erdafitinib, the median duration of treatment was 4.8 months (range: 0.1 to 43 months). In this pooled safety population, the most common (>20%) adverse reactions, including laboratory abnormalities, were increased phosphate, nail disorders, stomatitis, diarrhea, increased creatinine, increased alkaline phosphatase, increased alanine aminotransferase, decreased hemoglobin, decreased sodium, increased aspartate aminotransferase, fatigue, dry mouth, dry skin, decreased phosphate, decreased appetite, dysgeusia, constipation, increased calcium, dry eye, palmar-plantar erythrodysesthesia syndrome, increased potassium, alopecia, and central serous retinopathy. BLC3001 The safety of Erdafitinib was evaluated in Cohort 1 of the BLC3001 study that included patients with locally advanced unresectable or metastatic urothelial carcinoma which had susceptible FGFR3 genetic alterations and were previously treated with a PD-1 or PD-L1 inhibitor. Patients received either Erdafitinib (8 mg orally once daily with individualized up-titration to 9 mg) (n=135) or chemotherapy (docetaxel 75 mg/m 2 once every 3 weeks or vinflunine 320 mg/m 2 once every 3 weeks) (n=112).
