For Intravesical Use Only. ( 2.1 ) VALSTAR is recommended at a dose of 800 mg administered intravesically once a week for six weeks. ( 2.1 ) Delay administration at least two weeks after transurethral resection and/or fulguration. ( 2.1 ) Warm VALSTAR slowly to room temperature, but do not heat. ( 2.1 ) Use caution when handling and preparing the solution of VALSTAR. ( 2.2 ) 2.1 Recommended Dosing For Intravesical Use Only. Do NOT administer by intravenous or intramuscular routes. VALSTAR is recommended at a dose of 800 mg administered intravesically once a week for six weeks. Delay administration at least two weeks after transurethral resection and/or fulguration [ see Warnings and Precautions ( 5.2 , 5.3 )]. 2.2 Preparation, Handling, and Administration Handle and dispose of VALSTAR in a manner consistent with other cytotoxic drugs. 1 The use of goggles, gloves, and protective gowns is recommended during preparation and administration of the drug. VALSTAR contains polyoxyl castor oil, which has been known to cause leaching of di(2-ethylhexyl) phthalate (DEHP) a hepatotoxic plasticizer, from polyvinyl chloride (PVC) bags and intravenous tubing. VALSTAR should be prepared and stored in glass, polypropylene, or polyolefin containers and tubing. It is recommended that non-DEHP containing administration sets, such as those that are polyethylene-lined, be used. VALSTAR is a…

The most frequently reported adverse reactions ( > 5%) after administration of VALSTAR are urinary frequency, dysuria, urinary urgency, bladder spasm, hematuria, bladder pain, urinary incontinence, cystitis, urinary tract infection, nocturia, local burning symptoms, abdominal pain, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Endo at 1-800-462-3636 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial 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 safety of VALSTAR was assessed in 230 patients with transitional cell carcinoma of the bladder, including 205 patients who received multiple weekly doses. One hundred seventy-nine of the 205 patients received the approved dose and schedule of 800 mg weekly for multiple weeks. Approximately 84% of patients who received intravesical VALSTAR in clinical studies experienced local adverse reactions. The local adverse reactions associated with VALSTAR usually occur during or shortly after instillation and resolve within 1 to 7 days after the instillate is removed from the bladder. Seven out of 143 patients (5%) who were scheduled to receive six doses of VALSTAR failed to…

VALSTAR is contraindicated in patients with: Perforated bladder [ see Warnings and Precautions ( 5.2 )] Known hypersensitivity to anthracyclines or polyoxyl castor oil Active urinary tract infection Small bladder capacity and unable to tolerate a 75 mL instillation Perforated bladder or compromised bladder mucosa ( 4 , 5.2 ) Hypersensitivity to anthracyclines or polyoxyl castor oil. ( 4 ) Concurrent urinary tract infections. ( 4 ) Patients with a small bladder capacity unable to tolerate a 75 mL instillation. ( 4 )

There is no known antidote for overdoses of VALSTAR. The primary anticipated complications of overdosage associated with intravesical administration would be consistent with irritable bladder symptoms. Myelosuppression is possible if VALSTAR is inadvertently administered systemically or if significant systemic exposure occurs following intravesical administration (e.g., in patients with bladder rupture/perforation). Under such inadvertent exposures in the peritoneal cavity, the expected toxicities include leukopenia and neutropenia, beginning within 1 week of dose administration, with nadirs by the second week, and recovery generally by the third week. If VALSTAR is administered when bladder rupture or perforation is suspected, weekly monitoring of complete blood counts should be performed for 3 weeks.
