ZUSDURI™ is indicated for the treatment of adult patients with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC).
ZUSDURI is an alkylating drug indicated for the treatment of adult patients with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC). (1)
Administer ZUSDURI by intravesical instillation only. Do not administer by pyelocalyceal instillation or by any other route.
The recommended dose of ZUSDURI is 75 mg (56 mL) instilled once weekly for six weeks into the bladder via a urinary catheter. [see Dosage and Administration (2.4)]
See the Instructions for Pharmacy enclosed in the carton for complete information on preparation.
ZUSDURI must be reconstituted with sterile hydrogel under chilled conditions. Reconstituted ZUSDURI has reverse thermal properties with a gelation point of approximately 19°C (66°F) and will appear as a viscous liquid under chilled conditions and a semisolid gel at room temperature.
Storage Instructions for Reconstituted ZUSDURI:
ZUSDURI is a hazardous drug. Follow applicable special handling and disposal procedures.1
See the Instructions for Administration enclosed in the carton for complete information on bladder instillation.
ZUSDURI must be chilled at -3°C to 5°C (27°F to 41°F) to convert to a viscous liquid prior to instillation. When instilling ZUSDURI, each syringe must be emptied within thirty (30) seconds to avoid gelation.
Instillation of ZUSDURI requires syringes and a urinary catheter with fixed Luer Lock connectors.
Advise patients that ZUSDURI may discolor urine to a violet to blue color following the instillation procedure. Advise patients for at least 24 hours post-instillation to avoid urine contact with skin, to void urine sitting on a toilet, to wash hands and genital area with water and soap after each urination, and to flush the toilet several times after use.
For intravesical solution: A kit containing the following:
ZUSDURI is contraindicated in patients with:
ZUSDURI may lead to systemic exposure to mitomycin and severe adverse reactions if administered to patients with a perforated bladder or to those in whom the integrity of the bladder mucosa has been compromised.
Evaluate the bladder before the intravesical instillation of ZUSDURI and do not administer to patients with a perforated bladder or mucosal compromise until bladder integrity has been restored [see Contraindications (4)].
Based on findings in animals and mechanism of action, ZUSDURI can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of mitomycin resulted in teratogenicity. Advise females of reproductive potential to use effective contraception during treatment with ZUSDURI and for 6 months following the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ZUSDURI and for 3 months following the last dose [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].
The most common (≥ 10%) adverse reactions, including laboratory abnormalities, that occurred in patients were increased creatinine, increased potassium, dysuria, decreased hemoglobin, increased aspartate aminotransferase, increased alanine aminotransferase, increased eosinophils, decreased lymphocytes, urinary tract infection, decreased neutrophils, and hematuria. (6.1)
To report SUSPECTED ADVERSE REACTIONS, contact UroGen Pharma at 1-855-987-6436 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect rates observed in practice.
The safety of ZUSDURI was evaluated in ENVISION, a single-arm, multicenter study in 240 patients with recurrent LG-IR-NMIBC [see Clinical Studies (14)]. Patients received 75 mg ZUSDURI instilled once a week for 6 consecutive weeks. The median number of doses of ZUSDURI administered to patients was 6 (range 1-6) doses and 228 patients (95%) received all six scheduled doses.
Serious adverse reactions occurred in 12% of patients who received ZUSDURI, including urinary retention (0.8%) and urethral stenosis (0.4%). A fatal adverse reaction of cardiac failure occurred in 1 patient (0.4%) receiving ZUSDURI.
Permanent discontinuation of ZUSDURI due to an adverse reaction occurred in 2.9% of patients, including 1.7% who discontinued due to a renal or urinary disorder.
Dosage interruption of ZUSDURI due to adverse reactions occurred in 10% of patients. Adverse reactions (≥ 2%) which required dosage interruption were urinary tract infection (2.5%) and dysuria (2.5%).
The most common (≥ 10%) adverse reactions, including laboratory abnormalities, that occurred in patients were increased creatinine, increased potassium, dysuria, decreased hemoglobin, increased aspartate aminotransferase, increased alanine aminotransferase, increased eosinophils, decreased lymphocytes, urinary tract infection, decreased neutrophils, and hematuria.
Table 1 summarizes the adverse reactions in ENVISION.
Clinically relevant adverse reactions occurring in < 10% of patients receiving ZUSDURI in ENVISION included increased urinary frequency, fatigue, urinary incontinence, urinary retention, urethral stenosis, genital pain, urinary urgency, genital edema, genital pruritus, genital rash, urethritis, acute kidney injury, balanoposthitis, and nocturia.
Table 2 summarizes laboratory abnormalities in ENVISION.
Lactation: Advise not to breastfeed. (8.2)
Risk Summary
Based on findings in animals and mechanism of action, ZUSDURI can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on ZUSDURI use in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of mitomycin resulted in teratogenicity (see Data). Advise pregnant women of the potential risk to a fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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
Teratological changes have been noted with mitomycin in animal studies.
Risk Summary
There are no data on the presence of mitomycin in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ZUSDURI and for 1 week following the last dose.
ZUSDURI can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating ZUSDURI.
Contraception
Females
Advise females of reproductive potential to use effective contraception during treatment with ZUSDURI and for 6 months following the last dose.
Males
Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ZUSDURI and for 3 months following the last dose.
Safety and efficacy in pediatric patients have not been established.
Of the 240 patients receiving ZUSDURI in the ENVISION study, 162 (68%) were 65 years of age and older and 89 (37%) were 75 years of age and older. No significant overall differences in safety or efficacy were observed in patients 65 years of age and older, and in patients 75 years of age and older, compared to younger patients.
Avoid use of ZUSDURI in patients with severe renal impairment (estimated glomerular filtration rate [eGFR] < 30 mL/min). A higher incidence of hematuria and urinary tract infections was observed in patients with moderate renal impairment (eGFR 30 to <60 mL/min). Monitor patients with moderate renal impairment for increased adverse reactions. No dosage adjustments are recommended in patients with mild (eGFR 60 to <90 mL/min) or moderate renal impairment.
Mitomycin (also known as mitomycin-C) is an alkylating drug isolated from the broth of Streptomyces. Mitomycin is a blue-violet crystalline powder with a molecular formula of C15H18N4O5, and a molecular weight of 334.33. Its chemical name is 7-amino-9α-methoxymitosane, and it has the following structural formula:
Mitomycin is heat stable, has a high melting point, and is freely soluble in organic solvents.
ZUSDURI is supplied in a kit containing two vials of sterile lyophilized mitomycin for intravesical solution, 40 mg each, and one vial of 60 mL of sterile hydrogel, to be used as a vehicle for reconstitution.
Mitomycin for intravesical solution is a sterile, lyophilized, grey to greyish-purple, cake or powder that contains mitomycin 40 mg and mannitol 80 mg in each vial.
Hydrogel is a sterile, clear, colorless gel with or without bubbles at room temperature or clear, colorless liquid at 2°C to 8°C (36°F to 46°F), which contains 0.11 g hydroxypropyl methylcellulose, 17.12 g poloxamer, 0.63 g polyethylene glycol, and water for injection in each vial.
Once reconstituted, ZUSDURI is a clear, purple, viscous liquid at 2°C to 8°C (36°F to 46°F) or semisolid gel at room temperature, which may contain a few visible particles and have a pH between 6.0 and 8.0.
Mitomycin inhibits the synthesis of deoxyribonucleic acid (DNA). The guanine and cytosine content correlates with the degree of mitomycin-induced cross-linking. At high concentrations of the drug, cellular RNA and protein synthesis are also suppressed.
Mitomycin exposure-response relationships and time course of pharmacodynamic response are unknown.
The systemic exposure of mitomycin following instillation of 75 mg of mitomycin as ZUSDURI into the bladder was evaluated pre-instillation and hourly for up to six hours post-instillation in six patients. Mitomycin mean (range) maximum concentration (Cmax) is 2.3 ng/mL (0.2 to 8.9 ng/mL), which is less than 1% of the expected Cmax after intravenous administration.
Metabolism
Mitomycin is metabolized primarily in the liver, but metabolism occurs in other tissues as well. It is believed that the rate of clearance is inversely proportional to the maximal serum concentration because of saturation of the degradative pathways.
Excretion
Following instillation into the bladder, ZUSDURI forms a semisolid gel which dissolves in the urine. Patients reported visible gel in urine for up to 24 hours (median 5 hours) after instillation. Mitomycin is excreted unchanged in the urine. Systemically absorbed mitomycin is rapidly cleared from the serum and approximately 10% is excreted unchanged in the urine.
Adequate long-term studies in animals to evaluate carcinogenic potential from instillation of mitomycin into the bladder have not been conducted. Mitomycin has been found to be carcinogenic in rats and mice. At doses approximating the recommended intravenous clinical dose in humans, mitomycin produced a greater than 100% increase in tumor incidence in male Sprague-Dawley rats, and a greater than 50% increase in tumor incidence in female Swiss mice.
The effect of ZUSDURI on fertility is unknown.
ENVISION Study
The efficacy of ZUSDURI was evaluated in ENVISION (NCT05243550), a single-arm, multicenter trial in 240 adults with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC), of whom 223 were evaluable for response.
LG-IR-NMIBC was defined as Ta disease, histologically confirmed by biopsy, having one or two of the following: the presence of multiple tumors, a solitary tumor > 3 cm, and/or early or frequent recurrence (≥ 1 occurrence of LG-NMIBC within 1 year of the current diagnosis). Patients were required to have a previous occurrence of LG-NMIBC (Ta) treated by TURBT. The trial excluded patients with T1 tumors, or history of high-grade NMIBC within the previous two years, and/or those with prior intravesical chemotherapy within the prior two years (except for a single dose of intravesical chemotherapy immediately after any previous TURBT) and/or Bacillus Calmette-Guerin treatment within the previous year.
Patients received 75 mg ZUSDURI via urinary catheter once a week for 6 weeks.
Assessment of tumor status was performed every 3 months by cystoscopy, for-cause biopsy, and urine cytology. The major efficacy outcome measures were complete response rate (CR) at 3 months (defined as no detectable disease in the bladder by cystoscopy, biopsy [if indicated], and urine cytology) and duration of response.
The median age of patients was 70 years (range, 30-92 years); 62% were male; race was White (97.8%), Black (0.9%), Asian (0.9%), or not reported (0.4%); 1.3% were Hispanic/Latino. Multiple tumors were present in 84% of patients, 6% had a tumor > 3 cm, 55% had a previous LG-NMIBC occurrence within 1 year of the current diagnosis, and all patients had a prior TURBT for LG-NMIBC.
Efficacy results are summarized in Table 3.
