1 INDICATIONS AND USAGE
BALVERSA is indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma (mUC) with susceptible FGFR3genetic 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 BALVERSA [see Dosage and Administration (2.1)and Clinical Studies (14.1)] .
Limitations of Use
BALVERSA is not recommended for the treatment of patients who are eligible for and have not received prior PD-1 or PD-L1 inhibitor therapy [see Clinical Studies (14.1)] .
-
2 DOSAGE AND ADMINISTRATION
2.1 Patient Selection
Select patients for the treatment of locally advanced or metastatic urothelial carcinoma with BALVERSA based on the presence of susceptible FGFR3genetic alterations in tumor specimens as detected by an FDA-approved companion diagnostic [see Clinical Studies (14.1)] .
Information on FDA-approved tests for the detection of FGFR3genetic alterations in urothelial cancer is available at: http://www.fda.gov/CompanionDiagnostics.
2.2 Recommended Dosage and Schedule
The recommended starting dose of BALVERSA is 8 mg (two 4 mg tablets) orally once daily, with a dose increase to 9 mg (three 3 mg tablets) once daily based on tolerability, including hyperphosphatemia, at 14 to 21 days [see Dosage and Administration (2.3)].
Swallow tablets whole with or without food. If vomiting occurs any time after taking BALVERSA, the next dose should be taken the next day. Treatment should continue until disease progression or unacceptable toxicity occurs.
If a dose of BALVERSA is missed, it can be taken as soon as possible on the same day. Resume the regular daily dose schedule for BALVERSA the next day. Extra tablets should not be taken to make up for the missed dose.
Dose Increase based on Serum Phosphate Levels
Assess serum phosphate levels 14 to 21 days after initiating treatment. Increase the dose of BALVERSA to 9 mg once daily if serum phosphate level is < 9.0 mg/dL and there are no ocular disorders or Grade 2 or greater adverse reactions. If the phosphate level is 9.0 mg/dL or higher follow the relevant dose modifications in Table 2. Monitor phosphate levels monthly for hyperphosphatemia [see Pharmacodynamics (12.2)] .
2.3 Dose Modifications for Adverse Reactions

5 WARNINGS AND PRECAUTIONS
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)] .

6 ADVERSE REACTIONS
The following serious adverse reactions are also described elsewhere in the labeling:
- Ocular Disorders [see Warnings and Precautions (5.1)] .
- Hyperphosphatemia [see Warnings and Precautions (5.2)] .
6.1 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 BALVERSA as a single agent at the recommended dose (8 to 9 mg orally daily) in 479 patients with advanced urothelial cancer and FGFRalterations in 42756493BLC3001 (NCT03390504), 42756493BLC2001 (NCT02365597), 42756493BLC2002 (NCT 03473743), and 42756493EDI1001 (NCT01703481). Among 479 patients who received BALVERSA, 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 BALVERSA was evaluated in Cohort 1 of the BLC3001 study that included patients with locally advanced unresectable or metastatic urothelial carcinoma which had susceptible FGFR3genetic alterations and were previously treated with a PD-1 or PD-L1 inhibitor [see Clinical Studies (14.1)] . Patients received either BALVERSA (8 mg orally once daily with individualized up-titration to 9 mg) (n=135) or chemotherapy (docetaxel 75 mg/m 2once every 3 weeks or vinflunine 320 mg/m 2once every 3 weeks) (n=112). Among patients who received BALVERSA, median duration of treatment was 4.8 months (range: 0.2 to 38 months).
Serious adverse reactions occurred in 41% of patients who received BALVERSA. Serious reactions in >2% of patients included urinary tract infection (4.4%), hematuria (3.7%), hyponatremia (2.2%), and acute kidney injury (2.2%). Fatal adverse reactions occurred in 4.4% of patients who received BALVERSA, including sudden death (1.5%), pneumonia (1.5%), renal failure (0.7%), and cardiorespiratory arrest (0.7%).
Permanent discontinuation of BALVERSA due to an adverse reaction occurred in 14% of patients. Adverse reactions which resulted in permanent discontinuation of BALVERSA in >2% of patients included nail disorders (3%) and eye disorders (2.2%).
Dosage interruptions of BALVERSA due to an adverse reaction occurred in 72% of patients. Adverse reactions which required dosage interruption in >4% of patients included nail disorders (22%), stomatitis (19%), eye disorders (16%), palmar-plantar erythrodysesthesia syndrome (15%), diarrhea (10%), hyperphosphatemia (7%), increased aspartate aminotransferase (6%), and increased alanine aminotransferase (5%).
Dose reductions of BALVERSA due to an adverse reaction occurred in 69% of patients. Adverse reactions which required dose reductions in >4% of patients included nail disorders (27%), stomatitis (19%), eye disorders (17%), palmar-plantar erythrodysesthesia syndrome (12%), diarrhea (7%), dry mouth (4.4%), and hyperphosphatemia (4.4%).

7 DRUG INTERACTIONS
7.1 Effect of Other Drugs on BALVERSA
Table 7 summarizes drug interactions that affect the exposure of BALVERSA or serum phosphate level and their clinical management.
Table 7: Drug Interactions that Affect BALVERSA Moderate CYP2C9 or Strong CYP3A4 Inhibitors Clinical Impact - Co-administration of BALVERSA with moderate CYP2C9 or strong CYP3A4 inhibitors increased erdafitinib plasma concentrations [see Clinical Pharmacology (12.3)].
- Increased erdafitinib plasma concentrations may lead to increased drug-related toxicity [see Warnings and Precautions (5)].
Clinical Management - Consider alternative therapies that are not moderate CYP2C9 or strong CYP3A4 inhibitors during treatment with BALVERSA.
- If co-administration of a moderate CYP2C9 or strong CYP3A4 inhibitor is unavoidable, monitor closely for adverse reactions and consider dose modifications accordingly [see Dosage and Administration (2.3)]. If the moderate CYP2C9 or strong CYP3A4 inhibitor is discontinued, resume the BALVERSA dose before dose modifications in the absence of drug-related toxicity.
Strong CYP3A4 Inducers Clinical Impact - Co-administration of BALVERSA with strong CYP3A4 inducers decreased erdafitinib plasma concentrations [see Clinical Pharmacology (12.3)].
- Decreased erdafitinib plasma concentrations may lead to decreased activity.
Clinical Management - Avoid co-administration of strong CYP3A4 inducers with BALVERSA.
Moderate CYP3A4 Inducers Clinical Impact - Co-administration of BALVERSA with moderate CYP3A4 inducers may decrease erdafitinib plasma concentrations [see Clinical Pharmacology (12.3)].
- Decreased erdafitinib plasma concentrations may lead to decreased activity.
Clinical Management - If a moderate CYP3A4 inducer must be co-administered at the start of BALVERSA treatment, administer BALVERSA at a dose of 9 mg daily.
- When a moderate CYP3A4 inducer is discontinued, continue BALVERSA at the same dose, in the absence of drug-related toxicity.
Serum Phosphate Level-Altering Agents Clinical Impact - Co-administration of BALVERSA with other serum phosphate level-altering agents may increase or decrease serum phosphate levels [see Pharmacodynamics (12.2)].
- Changes in serum phosphate levels due to serum phosphate level-altering agents (other than erdafitinib) may interfere with serum phosphate levels needed for the determination of initial dose increased based on serum phosphate levels [see Dosage and Administration (2.3)].
Clinical Management - Avoid co-administration of serum phosphate level-altering agents with BALVERSA before initial dose increase period based on serum phosphate levels (Days 14 to 21) [see Dosage and Administration (2.3)].
7.2 Effect of BALVERSA on Other Drugs
Table 8 summarizes the effect of BALVERSA on other drugs and their clinical management.
Table 8: BALVERSA Drug Interactions that Affect Other Drugs P-glycoprotein (P-gp) Substrates Clinical Impact - Co-administration of BALVERSA with P-gp substrates may increase the plasma concentrations of P-gp substrates [see Clinical Pharmacology (12.3)].
- Increased plasma concentrations of P-gp substrates may lead to increased toxicity of the P-gp substrates.
Clinical Management - If co-administration of BALVERSA with P-gp substrates is unavoidable, separate BALVERSA administration by at least 6 hours before or after administration of P-gp substrates with narrow therapeutic index.

8 USE IN SPECIFIC POPULATIONS
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
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.
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)] .

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Erdafitinib is a kinase inhibitor that binds to and inhibits enzymatic activity of FGFR1, FGFR2, FGFR3 and FGFR4 based on in vitrodata. Erdafitinib inhibited FGFR phosphorylation and signaling and decreased cell viability in cell lines expressing FGFRgenetic alterations, including point mutations, amplifications, and fusions. 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 maxand 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).
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 maxand AUC infwere 121% and 148%, respectively, when BALVERSA was co-administered with fluconazole, a moderate CYP2C9 and CYP3A4 inhibitor, relative to BALVERSA administered alone.
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.
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.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility
Carcinogenicity studies have not been conducted with erdafitinib.
Erdafitinib was not mutagenic in a bacterial reverse mutation (Ames) assay and was not clastogenic in an in vitromicronucleus or an in vivorat bone marrow micronucleus assay.
Fertility studies in animals have not been conducted with erdafitinib. In the 3-month repeat-dose toxicity study, erdafitinib showed effects on female reproductive organs (necrosis of the ovarian corpora lutea) in rats at an exposure less than the human exposure (AUC) at maximum recommended human dose.

14 CLINICAL STUDIES
14.1 Urothelial Carcinoma with Susceptible FGFR3Genetic Alterations
The efficacy of BALVERSA was evaluated in Study BLC3001 (NCT03390504) Cohort 1, a randomized, open-label, multicenter study in which 266 patients with advanced urothelial cancer harboring selected FGFR3alterations were randomized 1:1 to receive BALVERSA (8 mg with titration up to 9 mg) versus chemotherapy (docetaxel 75 mg/m 2once every 3 weeks or vinflunine 320 mg/m 2once every 3 weeks) until unacceptable toxicity or progression. 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. FGFR3genetic alterations were identified from tumor tissue in a central laboratory by the QIAGEN therascreen®FGFRRGQ 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 FGFR3mutations, 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 BLC3001 Cohort 2
Study BLC3001 (NCT03390504) Cohort 2 was a multicenter, open-label, randomized study in 351 patients with locally advanced or metastatic urothelial carcinoma with selected FGFR3alterations who received 1 prior line of systemic therapy and no prior PD-1 or PD-L1 inhibitor. Patients were randomized 1:1 to receive BALVERSA (8 mg with titration up to 9 mg) or pembrolizumab 200 mg every 3 weeks. The study did not meet its major efficacy outcome measure for superiority of OS at the pre-specified final analysis. The OS hazard ratio (HR) was 1.18 (95% CI: 0.92, 1.51; p=0.18), median 10.9 (95% CI: 9.2, 12.6) months for BALVERSA versus 11.1 (95% CI: 9.7, 13.6) months for pembrolizumab [see Indications and Usage (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). FGFRmutation 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: FGFR3gene mutations ( R248C, S249C, G370C, Y373C) or FGFRgene 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®FGFRRGQ 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%. Responders included patients who had previously not responded to anti PD-L1/PD-1 therapy.
