Abstract Background We present the study rationale and design of the JGOG3023 study, an open-label, parallel-arm, randomized, phase II trial that aimed to assess the efficacy and safety of chemotherapy with or without bevacizumab in patients with platinum-resistant recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who were previously treated with bevacizumab for front-line or platinum-sensitive ovarian cancer. We hypothesize that patients treated with a combination of single-agent chemotherapy and bevacizumab will show improved progression-free survival (PFS) compared with those treated with single-agent chemotherapy alone, in the setting beyond disease progression following prior bevacizumab treatment. Methods/design A total of 106 patients who have recurrence or progression of ovarian cancer, while receiving chemotherapy or within 6 months after the final dose of platinum, after completing at least three cycles of bevacizumab plus platinum chemotherapy will be randomized in a 1:1 ratio to treatment with single-agent chemotherapy or single-agent chemotherapy combined with bevacizumab. For chemotherapy, one of the following four drugs will be chosen by an investigator: pegylated liposomal doxorubicin, topotecan, paclitaxel, or gemcitabine. The primary endpoint is investigator-assessed PFS. The secondary endpoints are overall survival, objective response rate, number of paracentesis, and response rate by CA125. Safety will be evaluated by the incidence of adverse events. Discussion This study will assess the efficacy and safety of bevacizumab in combination with single-agent chemotherapy, which could be used continuously after disease progression following standard platinum-based chemotherapy with bevacizumab. Trial registration UMIN000017247 (registered April 22, 2015).
