A Study of Intravesical Enfortumab Vedotin For Treatment of Patients With Non-muscle Invasive Bladder Cancer (NMIBC)
Trial Status: administratively complete
This study will test a drug called enfortumab vedotin in participants with a type of
bladder cancer called non-muscle invasive bladder cancer (NMIBC).
This study will also evaluate what the side effects are and if the drug works to treat
NMIBC. A side effect is anything a drug does to your body besides treating your disease.
In this study enfortumab vedotin will be put into the bladder using a catheter. A
catheter is a thin tube that can be put into your bladder.
Inclusion Criteria
Histologically confirmed, non-muscle invasive urothelial carcinoma with carcinoma in situ (CIS) (with or without papillary disease)
Predominant histologic component (>50 percent) must be urothelial (transitional cell) carcinoma
Participants must have high-risk Bacillus Calmette-Guerin (BCG) - unresponsive disease, defined as (where adequate BCG therapy is defined as one of the following: 5 of 6 doses of an initial induction course + at least 2 of 3 doses maintenance therapy or 5 of 6 doses of an initial induction course + at least 2 of 6 doses of a second induction course):
Persistent or recurrent CIS alone or with recurrent Ta/T1 (noninvasive papillary disease/tumor invades the subepithelial connective tissue) disease within 12 months of completion of adequate BCG therapy.
Recurrent high-grade Ta/T1 disease within 6 months of completion of adequate BCG therapy, or
T1 high-grade disease at the first evaluation following an induction BCG course (at least 5 or 6 doses)
Participant must be ineligible for or refusing a radical cystectomy
All visible papillary Ta/T1 tumors must be completely resected within 60 days prior to enrollment.
Eastern Cooperative Oncology Group Performance Status score of 0, 1, or 2.
Exclusion Criteria
Current or prior history of muscle-invasive urothelial carcinoma or metastatic disease.
Nodal or metastatic disease as noted on computed tomography (CT) or magnetic resonance imaging (MRI) within 3 months prior to study treatment
Concomitant upper tract urothelial carcinoma as noted on CT or MRI urogram performed within 3 months prior to study treatment
Prior or concomitant urothelial carcinoma of the prostatic urethra within 6 months prior to study treatment
Participants with tumor-related hydronephrosis
Participant has received other systemic anticancer therapy including chemotherapy, biologic therapy, immunotherapy, targeted therapy, endocrine therapy, and/or investigational agent within 4 weeks or intravesical therapy within 6 weeks of first dose of study treatment
Participant has had any prior radiation to the bladder for urothelial cancer
