Get patients startedZUSDURI delivers prolonged dwell time through its advanced RTGel® technology1
RTGel is a reverse-thermal hydrogel that is instilled as a chilled liquid and transforms into a gel at body temperature, allowing for prolonged drug exposure2
Median dwell time of 5 hours, with reports of up to 24 hours1*
1
Instillation2
RTGel combined with mitomycin is instilled into the bladder as a chilled liquid
2
Gel Forms2
As the liquid reaches body temperature, it becomes a semisolid gel in the bladder
3
Dwell Time1
It dissolves gradually as urine forms and exits naturally via urine
Enhanced Technology for Local Delivery1,3
- No need for urine retention
- No need to rotate positions
- Low systemic exposure: Following instillation of ZUSDURI, mean plasma concentrations were <1% of the expected Cmax after intravenous administration†
Advise Patients1:
- 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
*Based on patient-reported visibility of gel in urine post-treatment. Advise patients for at least 24 hours post-instillation to avoid urine contact with skin.1
†Evaluated pre-instillation and hourly for up to 6 hours post-instillation.1

Indications and Usage
ZUSDURI™ is indicated for the treatment of adult patients with recurrent low-grade intermediate-risk non-muscle invasive bladder cancer (LG-IR-NMIBC).
IMPORTANT SAFETY INFORMATION
Contraindications
ZUSDURI is contraindicated in patients with perforation of the bladder or in patients with prior hypersensitivity reactions to mitomycin or any component of the product.
Warnings and Precautions
Risks in Patients with Perforated Bladder
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.
Embryo-Fetal Toxicity
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.
Adverse Reactions
Common Adverse Reactions
The most common (≥10%) adverse reactions, including laboratory abnormalities, that occurred in patients treated with ZUSDURI 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.
Additional Adverse Reactions Information
Clinically relevant adverse reactions occurring in <10% of patients who received ZUSDURI 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.
Use in Specific Populations
Lactation
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.
