Официальное название
A Clinical Study on the Safety and Efficacy of 9MW2821 in Patients With High-risk Non-muscle-invasive Bladder Cancer (NMIBC) That Have Previously Failed to Intravesical Therapy
Обзор
Assess the safety and efficacy of 9MW2821 in patients with high-risk non-muscle-invasive bladder cancer (NMIBC) who have previously failed to intravesical therapy. Provide a new treatment option for patients with NMIBC recurrence, reduce the risk of tumor recurrence, decrease the rate of radical bladder surgery, and enhance the quality of life for patients.
