Evaluation of Combined Bevacizumab and Intraperitoneal Carboplatin or Paclitaxel Therapy in a Mouse Model of Ovarian Cancer

The purpose of this was to evaluate the pharmacokinetics of bevacizumab following IP and IV administration, and to investigate combined bevacizumab therapy (IP or IV) with IP paclitaxel or carboplatin in a mouse model of ovarian cancer.
Bevacizumab pharmacokinetics were investigated following IV or IP dosing, and mice bearing peritoneal A2780 xenografts were treated with vehicle, IV or IP bevacizumab, IP paclitaxel, IP paclitaxel with co-administration of IV or IP bevacizumab, IP carboplatin, and IP carboplatin with co-administration of IV or IP bevacizumab. Survival time was defined as the time to death or the time to reach 120% of baseline body weight.
