简要总结
This is a phase II trial to evaluate the tolerability, efficacy, and immune outcomes of AGEN1884 plus AGEN2034 concurrent with cisplatin and gemcitabine in the neoadjuvant treatment of muscle-invasive, non-metastatic bladder cancer prior to radical cystectomy.
详细描述
We will begin with an initial safety run-in to establish the safety of the combination prior to expansion to the full planned phase II. The overall phase II will be an open-label, single arm study in two stages to evaluate the efficacy of the combination in pathologic downstaging of MIBC. Patients will receive four 21-day cycles of neoadjuvant therapy consisting of cisplatin and gemcitabine plus AGEN2034 in all 4 cycles and AGEN1884 in cycles 1 and 3. Patients will proceed to radical cystectomy within 10 weeks after the final dose of this therapy. The primary endpoint of pathologic tumor downstaging will be assessed at the time of cystectomy.

研究组 & 干预措施
Cisplatin, Gemcitabine plus human monoclonal antibodies
The safety run-in of the study will first enroll three patients who will begin treatment with cisplatin and gemcitabine plus AGEN2034 and AGEN1884 as outlined in the treatment plan. These first 3 patients will be assessed for DLTs and there will be a pause in enrollment until all three complete the DLT period. If there are no DLTs in the first 3 patients, we will proceed to further accrual to stage I of phase II. If there is 1 DLT in the initial 3 patients, we will enroll 3 additional patients to the safety run-in. If > 2 DLTs are experienced in the initial 3 patients, the study will be terminated, otherwise additional subjects will be enrolled into the phase ll first stage and reassessed after 2 cycles of therapy and proceed to planned surgery. If criteria are met to continue to the second stage of the Phase II portion of the study, additional patients will be enrolled for an anticipated total of 36 evaluable patients. Patients will be treated and endpoints evaluated.

结局指标
主要结局
Pathologic Tumor Downstaging of >T2 to pT0
时间窗: Completion of four 21 day cycles (approximately 10 weeks)
pT0 or pCR (defined as no residual tumor in bladder and lymph nodes on resected specimen). Surgery should be performed within 6 weeks after completing up to 4 cycles (last dose) of neoadjuvant therapy, but can be done up to 10 weeks after treatment ends to be evaluable. Otherwise this patient must be replaced for response evaluation.
次要结局
- Completion of Surgery(90 days)
- Evaluation of Safety and Tolerability of AGEN1884 Plus AGEN2034 Plus Cisplatin and Gemcitabine(Baseline to 90 days)
- Pathologic Downstaging to <T2 Rate(Baseline to Completion of four 21 day cycles (approximately 10 weeks))
- Progression-free Survival at 1 Year(1 year)
