There are no available data on BALVERSA use in pregnant women to inform a drug-associated risk. Oral administration of erdafitinib to pregnant rats during organogenesis caused malformations and embryo-fetal death at maternal exposures that were less than the human exposures at the maximum recommended human dose based on AUC (see Data ) . Advise pregnant women and females of reproductive potential of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Animal Data In an embryo-fetal toxicity study, erdafitinib was orally administered to pregnant rats during the period of organogenesis. Doses ≥4 mg/kg/day (at total maternal exposures <0.1% of total human exposures at the maximum recommended human dose based on AUC) produced embryo-fetal death, major blood vessel malformations and other vascular anomalies, limb malformations (ectrodactyly, absent or misshapen long bones), an increased incidence of skeletal anomalies in multiple bones (vertebrae, sternebrae, ribs), and decreased fetal weight."],"description":["11 DESCRIPTION Erdafitinib, the active ingredient in BALVERSA, is a kinase inhibitor.

Randomization was stratified by region (North America vs. Europe vs. rest of world), Eastern Cooperative Oncology Group (ECOG) performance status (0 or 1 vs. 2) and visceral or bone metastases (yes vs. no). All patients needed to have had disease progression after 1 or 2 prior treatments, at least 1 of which included a PD-1 or PD-L1 inhibitor. FGFR3 genetic alterations were identified from tumor tissue in a central laboratory by the QIAGEN therascreen ® FGFR RGQ RT-Polymerase Chain Reaction (PCR) kit in 75% of patients while the remainder (25%) were identified by local next generation sequencing (NGS) assays. The major efficacy outcome measures were overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) assessed by investigator using RECIST (Response Evaluation Criteria in Solid Tumors) Version 1.1. The median age was 67 years (range: 32 to 86 years) and 71% were male; 54% were White, 29% Asian, 0.4% Black, 0.4% multiple races, 16% not reported; 2% were Hispanic/Latino; and baseline ECOG performance status was 0 (43%), 1 (48%), or 2 (9%). Eighty-one percent of patients had FGFR3 mutations, 17% had fusions, and 2% had both mutations and fusions. Ninety-five percent of patients had pure transitional cell carcinoma (TCC) and 5% had TCC with other histologic variants. The primary tumor location was the upper tract for 33% of subjects and lower tract for 67%; 74% of patients had visceral or bone metastases. Eighty-eight percent of patients received platinum-containing chemotherapy previously. PD-1 or PD-L1 inhibitor therapy was received only in the neoadjuvant or adjuvant setting in 7% of patients. Statistically significant improvements in OS, PFS, and ORR were demonstrated for BALVERSA compared with chemotherapy. Table 9 and Figures 1 and 2 summarize the efficacy results for BLC3001 Cohort 1.

Study BLC2001 Study BLC2001 (NCT02365597) was a multicenter, open-label, single-arm study to evaluate the efficacy and safety of BALVERSA in patients with locally advanced or metastatic urothelial carcinoma (mUC). FGFR mutation status for screening and enrollment of patients was determined by a clinical trial assay (CTA). The efficacy population consists of a cohort of eighty-seven patients who were enrolled in this study with disease that had progressed on or after at least one prior chemotherapy and that had at least 1 of the following genetic alterations: FGFR3 gene mutations ( R248C , S249C , G370C , Y373C ) or FGFR gene fusions ( FGFR3-TACC3 , FGFR3-BAIAP2L1 , FGFR2-BICC1 , FGFR2-CASP7 ), as determined by the CTA performed at a central laboratory. Tumor samples from 69 patients were tested retrospectively by the QIAGEN therascreen ® FGFR RGQ RT-PCR Kit, which is the FDA-approved test for selection of patients with mUC for BALVERSA. Patients received a starting dose of BALVERSA at 8 mg once daily with a dose increase to 9 mg once daily in patients whose serum phosphate levels were below the target of 5.5 mg/dL between days 14 and 17; a dose increase occurred in 41% of patients. BALVERSA was administered until disease progression or unacceptable toxicity. The major efficacy outcome measures were ORR and duration of response (DoR), as determined by blinded independent review committee (BIRC) according to RECIST v1.1. The median age was 67 years (range: 36 to 87 years), 79% were male, and 74% were Caucasian. Most patients (92%) had a baseline Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Sixty-six percent of patients had visceral metastases. Eighty-four (97%) patients received at least one of cisplatin or carboplatin previously. Fifty-six percent of patients only received prior cisplatin-based regimens, 29% received only prior carboplatin-based regimens, and 10% received both cisplatin and carboplatin-based regimens. Three (3%) patients had disease progression following prior platinum-containing neoadjuvant or adjuvant therapy only. Twenty-four percent of patients had been treated with prior anti PD-L1/PD-1 therapy. Efficacy results are summarized in Table 10 and Table 11. ORR was 32.2%.

Following single and repeat once daily dosing of BALVERSA, erdafitinib exposure (C max and AUC) increased proportionally across the dose range of 0.5 to 12 mg (0.06 to 1.3 times the maximum approved recommended dose). Steady state was achieved after 2 weeks with once daily dosing with a mean accumulation ratio was 4-fold. Absorption Median time to achieve peak plasma concentration (t max ) was 2.5 hours (range: 2 to 6 hours). Effect of Food No clinically meaningful differences in erdafitinib exposure was observed following administration of BALVERSA with a high-fat and high-calorie meal (800 calories to 1,000 calories with approximately 50% of total caloric content of the meal from fat). Distribution The mean apparent volume of distribution of erdafitinib was 29 L. Erdafitinib protein binding was 99.7% in patients, primarily to alpha-1-acid glycoprotein. Elimination The mean total apparent clearance (CL/F) of erdafitinib was 0.362 L/h. The mean effective half-life of erdafitinib was 59 hours. Metabolism Erdafitinib is primarily metabolized by CYP2C9 and CYP3A4. The contribution of CYP2C9 and CYP3A4 in the total clearance of erdafitinib is estimated to be 39% and 20%, respectively. Unchanged erdafitinib was the major drug-related moiety in plasma, there were no circulating metabolites. Excretion Following a single oral dose of radiolabeled erdafitinib, approximately 69% of the dose was recovered in feces (19% as unchanged) and 19% in urine (13% as unchanged). Specific Populations No clinically meaningful effects on erdafitinib exposure were observed based on age (21–92 years), sex, race (White, Hispanic or Asian), body weight (36–166 kg), mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment, or mild to moderate renal impairment (eGFR 30 to 89 mL/min/1.73 m²). Limited data are available in patients with severe (Child-Pugh C) hepatic impairment and in patients with severe renal impairment. The pharmacokinetics of erdafitinib in patients with renal impairment requiring dialysis is unknown. Drug Interaction Studies Clinical Studies Effect of Other Drugs on Erdafitinib Moderate CYP2C9 Inhibitors Erdafitinib mean ratios for C max and AUC inf were 121% and 148%, respectively, when BALVERSA was co-administered with fluconazole, a moderate CYP2C9 and CYP3A4 inhibitor, relative to BALVERSA administered alone. Strong CYP3A4 Inhibitors Erdafitinib mean ratios for C max and AUC inf were 105% and 134%, respectively, when BALVERSA was co-administered with itraconazole (a strong CYP3A4 inhibitor and P-gp inhibitor) relative to BALVERSA alone. CYP3A4/2C9 Inducers Erdafitinib mean ratios for C max and AUC inf were 78% and 45%, respectively, when BALVERSA was co-administered with carbamazepine (a strong CYP3A4 and weak CYP2C9 inducer) relative to BALVERSA alone. Effect of Erdafitinib on Other Drugs CYP3A4 Substrates: No clinically meaningful effect on the exposure of midazolam (a CYP3A4 substrate) was observed following coadministration with BALVERSA. OCT2 Substrates : No clinically meaningful effect on the exposure of metformin (an OCT2 substrate) was observed following coadministration with BALVERSA. In Vitro Studies CYP Substrates Erdafitinib is a time dependent inhibitor and inducer of CYP3A4. Erdafitinib is not an inhibitor of other major CYP isozymes at clinically relevant concentrations. Transporters Erdafitinib is a substrate and inhibitor of P-gp. P-gp inhibitors are not expected to affect erdafitinib exposure to a clinically relevant extent. Erdafitinib is an inhibitor of OCT2. Erdafitinib does not inhibit BCRP, OATP1B, OATP1B3, OAT1, OAT3, OCT1, MATE-1, or MATE-2K at clinically relevant concentrations. Acid-Lowering Agents Erdafitinib has adequate solubility across the pH range of 1 to 7.4. Acid-lowering agents (including antacids, H 2 -antagonists and proton pump inhibitors) are not expected to affect the bioavailability of erdafitinib."],"adverse_reactions":["6 ADVERSE REACTIONS The following serious adverse reactions are also described elsewhere in the labeling: Ocular Disorders [see Warnings and Precautions (5.1) ] .

Erdafitinib demonstrated antitumor activity in FGFR-expressing cell lines and xenograft models derived from tumor types, including bladder cancer. 12.2 Pharmacodynamics Cardiac Electrophysiology Based on evaluation of QTc interval in an open-label, dose escalation and dose expansion study in 187 patients with cancer, erdafitinib had no large effect (i.e., > 20 ms) on the QTc interval. Serum Phosphate FGFR inhibition by BALVERSA increases serum phosphate level [see Dosage and Administration (2.3) and Drug Interactions (7.1) ]. 12.3 Pharmacokinetics Following administration of BALVERSA 8 mg once daily, the mean (coefficient of variation [CV%]) erdafitinib steady-state maximum plasma concentration (C max ), area under the curve (AUC tau ), and minimum plasma concentration (C min ) were 1,399 ng/mL (51%), 29,268 ng∙h/mL (60%), and 936 ng/mL (65%), respectively. Following single and repeat once daily dosing of BALVERSA, erdafitinib exposure (C max and AUC) increased proportionally across the dose range of 0.5 to 12 mg (0.06 to 1.3 times the maximum approved recommended dose). Steady state was achieved after 2 weeks with once daily dosing with a mean accumulation ratio was 4-fold. Absorption Median time to achieve peak plasma concentration (t max ) was 2.5 hours (range: 2 to 6 hours). Effect of Food No clinically meaningful differences in erdafitinib exposure was observed following administration of BALVERSA with a high-fat and high-calorie meal (800 calories to 1,000 calories with approximately 50% of total caloric content of the meal from fat). Distribution The mean apparent volume of distribution of erdafitinib was 29 L. Erdafitinib protein binding was 99.7% in patients, primarily to alpha-1-acid glycoprotein. Elimination The mean total apparent clearance (CL/F) of erdafitinib was 0.362 L/h. The mean effective half-life of erdafitinib was 59 hours. Metabolism Erdafitinib is primarily metabolized by CYP2C9 and CYP3A4. The contribution of CYP2C9 and CYP3A4 in the total clearance of erdafitinib is estimated to be 39% and 20%, respectively. Unchanged erdafitinib was the major drug-related moiety in plasma, there were no circulating metabolites. Excretion Following a single oral dose of radiolabeled erdafitinib, approximately 69% of the dose was recovered in feces (19% as unchanged) and 19% in urine (13% as unchanged). Specific Populations No clinically meaningful effects on erdafitinib exposure were observed based on age (21–92 years), sex, race (White, Hispanic or Asian), body weight (36–166 kg), mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment, or mild to moderate renal impairment (eGFR 30 to 89 mL/min/1.73 m²). Limited data are available in patients with severe (Child-Pugh C) hepatic impairment and in patients with severe renal impairment. The pharmacokinetics of erdafitinib in patients with renal impairment requiring dialysis is unknown. Drug Interaction Studies Clinical Studies Effect of Other Drugs on Erdafitinib Moderate CYP2C9 Inhibitors Erdafitinib mean ratios for C max and AUC inf were 121% and 148%, respectively, when BALVERSA was co-administered with fluconazole, a moderate CYP2C9 and CYP3A4 inhibitor, relative to BALVERSA administered alone. Strong CYP3A4 Inhibitors Erdafitinib mean ratios for C max and AUC inf were 105% and 134%, respectively, when BALVERSA was co-administered with itraconazole (a strong CYP3A4 inhibitor and P-gp inhibitor) relative to BALVERSA alone. CYP3A4/2C9 Inducers Erdafitinib mean ratios for C max and AUC inf were 78% and 45%, respectively, when BALVERSA was co-administered with carbamazepine (a strong CYP3A4 and weak CYP2C9 inducer) relative to BALVERSA alone. Effect of Erdafitinib on Other Drugs CYP3A4 Substrates: No clinically meaningful effect on the exposure of midazolam (a CYP3A4 substrate) was observed following coadministration with BALVERSA. OCT2 Substrates : No clinically meaningful effect on the exposure of metformin (an OCT2 substrate) was observed following coadministration with BALVERSA. In Vitro Studies CYP Substrates Erdafitinib is a time dependent inhibitor and inducer of CYP3A4. Erdafitinib is not an inhibitor of other major CYP isozymes at clinically relevant concentrations. Transporters Erdafitinib is a substrate and inhibitor of P-gp. P-gp inhibitors are not expected to affect erdafitinib exposure to a clinically relevant extent. Erdafitinib is an inhibitor of OCT2. Erdafitinib does not inhibit BCRP, OATP1B, OATP1B3, OAT1, OAT3, OCT1, MATE-1, or MATE-2K at clinically relevant concentrations. Acid-Lowering Agents Erdafitinib has adequate solubility across the pH range of 1 to 7.4. Acid-lowering agents (including antacids, H 2 -antagonists and proton pump inhibitors) are not expected to affect the bioavailability of erdafitinib. 12.5 Pharmacogenomics CYP2C9 activity is reduced in individuals with genetic variants, such as the CYP2C9*2 and CYP2C9*3 polymorphisms. Erdafitinib exposure was similar in subjects with CYP2C9*1/*2 and *1/*3 genotypes relative to subjects with CYP2C9*1/*1 genotype (wild type). No data are available in subjects characterized by other genotypes (e.g., *2/*2, *2/*3, *3/*3). Simulation suggested no clinically meaningful differences in erdafitinib exposure in subjects with CYP2C9*2/*2 and *2/*3 genotypes. The exposure of erdafitinib is predicted to be 50% higher in subjects with the CYP2C9*3/*3 genotype, estimated to be present in 0.4% to 3% of the population among various ethnic groups."],"indications_and_usage":["1 INDICATIONS AND USAGE BALVERSA 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.

Perform monthly ophthalmological examinations during the first four months of treatment, every 3 months afterwards, and at any time for visual symptoms. Withhold BALVERSA when CSR/RPED occurs and permanently discontinue if it does not resolve within 4 weeks or if Grade 4 in severity. ( 2.3 , 5.1 ) Hyperphosphatemia: Increases in phosphate levels are a pharmacodynamic effect of BALVERSA. Monitor for hyperphosphatemia and manage with dose modifications when required. ( 2.3 , 5.2 ) Embryo-fetal toxicity: Can cause fetal harm. Advise patients of the potential risk to the fetus and to use effective contraception ( 5.3 , 8.1 , 8.3) 5.1 Ocular Disorders BALVERSA can cause ocular disorders, including central serous retinopathy/retinal pigment epithelial detachment (CSR/RPED) resulting in visual field defect. In the pooled safety population [see Adverse Reactions (6) ] , CSR/RPED occurred in 22% of patients treated with BALVERSA, 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 BALVERSA-treated patients required permanent discontinuation for CSR. Of the 24 patients who restarted BALVERSA 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 BALVERSA-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 BALVERSA based on severity and/or ophthalmology exam findings [see Dosage and Administration (2.3) ] . 5.2 Hyperphosphatemia and Soft Tissue Mineralization BALVERSA 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 BALVERSA [see Pharmacodynamics (12.2) ]. In the pooled safety population [see Adverse Reactions (6) ], increased phosphate occurred in 73% of BALVERSA-treated patients. The median onset time of increased phosphate was 16 days (range: 8–421) after initiating BALVERSA. Twenty-four percent of patients received phosphate binders during treatment with BALVERSA. Vascular calcification was observed in 0.2% of patients treated with BALVERSA. 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. If serum phosphate is above 7.0 mg/dL, consider adding an oral phosphate binder until serum phosphate level returns to <7.0 mg/dL. Withhold, dose reduce, or permanently discontinue BALVERSA based on duration and severity of hyperphosphatemia according to Table 2 [see Dosage and Administration (2.3) ]. 5.3 Embryo-Fetal Toxicity Based on the mechanism of action and findings in animal reproduction studies, BALVERSA can cause fetal harm when administered to a pregnant woman. In an embryo-fetal toxicity study, oral administration of erdafitinib to pregnant rats during the period of organogenesis caused malformations and embryo-fetal death at maternal exposures that were less than the human exposures at the maximum human recommended dose based on area under the curve (AUC). Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception during treatment with BALVERSA and for one month after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with BALVERSA and for one month after the last dose [see Use in Specific Populations (8.1 , 8.3) and Clinical Pharmacology (12.1) ] ."],"clinical_studies_table":["

( 8.2 ) 8.1 Pregnancy Risk Summary Based on the mechanism of action and findings in animal reproduction studies, BALVERSA can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on BALVERSA use in pregnant women to inform a drug-associated risk. Oral administration of erdafitinib to pregnant rats during organogenesis caused malformations and embryo-fetal death at maternal exposures that were less than the human exposures at the maximum recommended human dose based on AUC (see Data ) . Advise pregnant women and females of reproductive potential of the potential risk to the fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Animal Data In an embryo-fetal toxicity study, erdafitinib was orally administered to pregnant rats during the period of organogenesis. Doses ≥4 mg/kg/day (at total maternal exposures <0.1% of total human exposures at the maximum recommended human dose based on AUC) produced embryo-fetal death, major blood vessel malformations and other vascular anomalies, limb malformations (ectrodactyly, absent or misshapen long bones), an increased incidence of skeletal anomalies in multiple bones (vertebrae, sternebrae, ribs), and decreased fetal weight. 8.2 Lactation Risk Summary There are no data on the presence of erdafitinib in human milk, or the effects of erdafitinib on the breastfed child, or on milk production. Because of the potential for serious adverse reactions from erdafitinib in a breastfed child, advise lactating women not to breastfeed during treatment with BALVERSA and for one month following the last dose. 8.3 Females and Males of Reproductive Potential BALVERSA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating treatment with BALVERSA. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with BALVERSA and for one month after the last dose. Males Advise male patients with female partners of reproductive potential to use effective contraception during treatment with BALVERSA and for one month after the last dose. Infertility Females Based on findings from animal studies, BALVERSA may impair fertility in females of reproductive potential [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use Safety and effectiveness of BALVERSA in pediatric patients have not been established. Skeletal adverse reactions have occurred in pediatric patients treated with BALVERSA. In a study of BALVERSA that included pediatric patients ages 6 to <18 years with FGFR-positive advanced solid tumors, epiphysiolysis and bone fractures occurred. In the postmarket setting and in literature reports, cases of slipped capital femoral epiphysis and accelerated linear growth in patients treated with BALVERSA have been reported. Juvenile Animal Toxicity Data In 4 and 13-week repeat-dose toxicology studies in rats and dogs, toxicities in bone and teeth were observed at an exposure less than the human exposure (AUC) at the maximum recommended human dose. Chondroid dysplasia/metaplasia were reported in multiple bones in both species, and tooth abnormalities included abnormal/irregular denting in rats and dogs and discoloration and degeneration of odontoblasts in rats. 8.5 Geriatric Use Of the 479 patients treated with BALVERSA in clinical studies, 40% of patients were less than 65 years old, 40% of patients were 65 years to 74 years old, and 20% were 75 years old and over. Patients 65 years of age and older treated with BALVERSA experienced a higher incidence of adverse reactions requiring treatment discontinuation than younger patients. In clinical trials, the incidence of treatment discontinuations of BALVERSA due to adverse reactions was 10% in patients younger than 65 years, 20% in patients ages 65–74 years, and 35% in patients 75 years or older. No overall difference in efficacy was observed between these patients and younger patients [see Clinical Studies (14.1) ]. 8.6 CYP2C9 Poor Metabolizers CYP2C9*3/*3 Genotype: Erdafitinib plasma concentrations are predicted to be higher in patients with the CYP2C9*3/*3 genotype. Monitor for increased adverse reactions in patients who are known or suspected to have CYP2C9*3/*3 genotype [see Pharmacogenomics (12.5) ] ."],"dosage_and_administration_table":["

carcinoma, positioning it in a niche but critical segment of oncology. Its key strength lies in its mechanism of action, which specifically targets the fibroblast growth factor receptor 1, offering a targeted therapy for patients with this receptor alteration. The primary risk to Balversa is the competitive landscape, with several same-class drugs such as pemigatinib, infigratinib, and futibatinib, all of which are patent-protected and have FDA approvals, potentially limiting market share and revenue growth.","approvals":[{"date":"2019-04-12","orphan":false,"company":"JANSSEN BIOTECH","regulator":"FDA"}],"brandName":"Balversa","ecosystem":[{"indication":"Metastatic urothelial carcinoma","otherDrugs":[{"name":"enfortumab vedotin","slug":"enfortumab-vedotin","company":"Astellas"}],"globalPrevalence":null}],"mechanism":{"target":"Fibroblast growth factor receptor 1","novelty":"Follow-on","targets":[{"gene":"FGFR1","source":"DrugCentral","target":"Fibroblast growth factor receptor 1","protein":"Fibroblast growth factor receptor 1"},{"gene":"FGFR2","source":"DrugCentral","target":"Fibroblast growth factor receptor 2","protein":"Fibroblast growth factor receptor 2"},{"gene":"FGFR3","source":"DrugCentral","target":"Fibroblast growth factor receptor 3","protein":"Fibroblast growth factor receptor 3"},{"gene":"FGFR4","source":"DrugCentral","target":"Fibroblast growth factor receptor 4","protein":"Fibroblast growth factor receptor 4"},{"gene":"KDR","source":"DrugCentral","target":"Vascular endothelial growth factor receptor 2","protein":"Vascular endothelial growth factor receptor 2"}],"moaClass":"Cytochrome P450 3A4 Inducers","modality":"Small Molecule","drugClass":"Kinase Inhibitor [EPC]","explanation":"Erdafitinib is kinase inhibitor that binds to and inhibits enzymatic activity of FGFR1, FGFR2, FGFR3 and FGFR4 based on in vitro data.

Erdafitinib inhibited FGFR phosphorylation and signaling and decreased cell viability in cell lines expressing FGFR genetic alterations, including point mutations, amplifications, and fusions.

The FDA also approved the FGFR RGQ RT-PCR Kit, developed by Qiagen Manchester, Ltd., for use as a companion diagnostic with erdafinitib for this therapeutic indication.\n\nIn January 2024, the FDA approved erdafitinib for adults with locally advanced or metastatic urothelial carcinoma with susceptible FGFR3 genetic alterations, as determined by an FDA-approved companion diagnostic test, whose disease has progressed on or after at least one line of prior systemic therapy. This approval amends the indication previously granted under accelerated approval for people with metastatic urothelial carcinoma with susceptible FGFR3 or FGFR2 alterations after prior platinum-containing chemotherapy. Efficacy was evaluated in Study BLC3001 Cohort 1, a randomized, open-label trial of 266 participants with metastatic urothelial carcinoma harboring selected FGFR3 alterations who had received 1-2 prior systemic treatments, including a PD-1 or PD-L1 inhibitor. Participants were randomized 1:1 to receive erdafitinib or investigator's choice of chemotherapy (docetaxel or vinflunine). Randomization was stratified by region, performance status, and presence of visceral or bone metastases. FGFR3 alterations were identified from tumor tissue in a central laboratory by the FGFR RGQ RT-PCR kit (Qiagen) in 75% of participants, while the remainder were identified by local next generation sequencing assays.","wiki_society_and_culture":"== Society and culture ==\n=== Legal status ===\nIn March 2018, erdafitinib was granted breakthrough therapy designation by the FDA for treatment of urothelial cancer.
