New drug combo aims to keep bladder cancer from coming back
NCT ID NCT07207824
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study tests whether adding the drug disitamab vedotin to standard BCG therapy can help keep high-risk, early-stage bladder cancer from returning. It includes 182 adults whose cancer has been surgically removed but is at high risk of coming back. Participants will receive either the drug combo or BCG alone, and researchers will track how long they stay cancer-free.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria 1. Age ≥ 18 years. 2. Histologically confirmed high-risk, non-muscle-invasive urothelial carcinoma of the bladder (UCC) (with \>50% urothelial carcinoma as the predominant histological component), defined by the presence of any of the following: a. T1 tumor; b. High-grade Ta tumor; c. Carcinoma in situ (CIS). 3. Complete resection of all Ta/T1 papillary lesions (including patients with concomitant CIS). The most recent Transurethral Resection of Bladder Tumor (TURBT) must have been performed within 12 weeks prior to randomization. A second TURBT was required if indicated per current local applicable guidelines. 4. HER2 expression (IHC 1+/2+/3+) as confirmed by immunohistochemistry (IHC) testing at the local institution's pathology department. 5. Unwillingness or ineligibility to undergo radical cystectomy. 6. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of ≤ 2. 7. Signed informed consent form (ICF). Exclusion Criteria 1. Histologically confirmed evidence of muscle-invasive (T2 or higher), locally advanced, or metastatic urothelial carcinoma, or the presence of concurrent extravesical non-muscle-invasive urothelial carcinoma. 2. Histopathological findings of pure small cell carcinoma, pure adenocarcinoma, pure squamous cell carcinoma, or pure squamous CIS of the bladder. 3. History of upper tract urothelial carcinoma (except for cases with no recurrence within 2 years following radical treatment for UTUC). 4. Prior therapy with any other type of HER2-targeted inhibitor. 5. Major surgery within 2 weeks prior to randomization. 6. Any other condition that, in the investigator's judgment, would make the patient unsuitable for participation in this study.
