Comparing two treatments for advanced urothelial carcinoma
A Randomized Phase II Trial to Evaluate 9MW2821 in Combination With Toripalimab Compared With 9MW2821 Monotherapy for the 1st Line Treatment of Locally Advanced or Metastatic Urothelial Carcinoma
This study is testing if a combination of two treatments can help people with advanced bladder cancer do better than using just one of the treatments alone.

What this trial studies
This study evaluates the effectiveness of a combination treatment of 9MW2821 and toripalimab against 9MW2821 alone in patients with locally advanced or metastatic urothelial carcinoma who have not previously received systemic therapy. Participants will be monitored for measurable tumor response according to established criteria. The trial aims to determine if the combination therapy offers improved outcomes compared to monotherapy in this patient population.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18-80 with histologically confirmed inoperable locally advanced or metastatic urothelial carcinoma who have not received prior systemic treatment.
Not a fit: Patients with other concurrent malignancies or those who have received prior systemic treatment for their condition may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a new effective treatment option for patients with advanced urothelial carcinoma.
How similar studies have performed: While this specific combination has not been widely tested, similar approaches in immunotherapy and targeted treatments have shown promise in other studies.

Have received prior treatment with Nectin-4 targeted therapy or ADC with MMAE as payload.
