New bladder cancer drug delivered directly into bladder shows early promise
NCT ID NCT05014139
First seen Jun 27, 2026 · Last updated Sep 15, 2026 · Updated 2 times
Summary
This early-phase trial tested enfortumab vedotin, a drug placed directly into the bladder via a catheter, in 37 people with a type of bladder cancer that did not respond to standard BCG therapy. The main goals were to check safety and side effects, and to see if the drug could help control the cancer. The study was terminated early, so full results are not yet available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- enfortumab vedotin (PADCEV)
- What this could lead to
- If it works, this could offer a new treatment option for people with bladder cancer that hasn't responded to standard therapy, potentially avoiding the need for bladder removal.
- What could go wrong
- This is a very early (Phase 1) trial that was terminated early, so results are limited. The drug may cause side effects and may not effectively control the cancer.

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
