Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
