Conditions: Uterine Cervical Neoplasms

Summary: bvac-c is an immunotherapeutic vaccine using b-cell and monocytes as antigen-presenting cells. this study is consists of 2 parts. phase i is for safety evaluation, and phase iia is for efficacy assessment.

bvac-c is an immunotherapeutic vaccine using b-cell and monocytes as antigen-presenting cells. this study is consists of 2 parts(phase i, phase ii). phase i study is open-label, dose-escalation, multiple dosing study to evaluate the safety, tolerability, immune response and preliminary efficacy of bvac-c in patients with multiple metastatic progressive or recurrent hpv type 16 or 18 positive cervical cancer after failure to standard care. 9\~18 patients will be enrolled in phase iia study, which open-label, sequential assignment multiple dosing study, efficacy, immune response and safety will be evaluated. total 21 patients will be enrolled in 3 groups.
