Feasibility of Home Instillation of UGN-102 for Treatment of Low-Grade (LG) Non-Muscle Invasive Bladder Cancer (NMIBC)

The primary objective of this study was to evaluate the feasibility of home instillation of UGN-102 as an alternative to instillation in a clinical setting. Feasibility was assessed by evaluation of safety and tolerability, rate of discontinuation from at home study treatment, and feedback from patients, home health professionals (HHPs), and investigators via standardized questionnaires. The secondary objective of this study was to evaluate the efficacy of UGN-102 for treatment of LG-IR-NMIBC following home instillation. Efficacy was assessed at the 3-month Visit (3 months after the first instillation of UGN-102) by the complete response rate (CRR), defined as the proportion of patients who achieved a complete response (CR) as determined by cystoscopy, for cause biopsy, and urine cytology. Patients who provided informed consent underwent a Screening Visit to determine eligibility. Screening procedures were to provide evidence of LG-NMIBC and to rule out evidence of high-grade (HG) disease. Eligible patients were to receive 6 once-weekly intravesical instillations of UGN-102. The first instillation was performed at the investigative site and subsequent instillations were performed at the patient's home by a trained HHP. The HHP was to call the patient 1 to 2 days after each home instillation of UGN-102 to monitor for safety. At each home instillation visit, the patient and HHP were to complete a feasibility questionnaire. In addition, the patient and investigator were to complete a feasibility questionnaire at the 3-month Visit (end of study) or Early Termination Visit. Patients were to return to the clinic for the 3-month Visit for determination of response to treatment. Response was determined based on visual evaluation by cystoscopy (white light) (appearance, number, and size of any remaining lesions), interpretation of urine cytology, and for cause biopsy and histopathology of any remaining lesions. Any lesions or suspect tissue were to be biopsied to evaluate for persistence of disease. Safety was evaluated based on review of adverse events (AEs), laboratory assessments, vital signs, and physical examination. A patient was considered to have completed the study if the patient completed the 3-month Visit. Following the 3-month Visit, all patients exited the study and continued with standard of care according to their treating physician.
