Dose Finding Study Of PF-05212384 With Paclitaxel And Carboplatin In Patients With Advanced Solid Tumor

This is a phase Ib single arm, open-label, multiple dose, dose escalating, safety, pharmacokinetic and pharmacodynamic study of the combination of PF-05212384 with paclitaxel and carboplatin. The study will be conducted in adult patients with advanced breast, NSCLC, ovarian or endometrial, small cell lung cancer (SCLC) and Head and Neck (HNSCC) cancer for whom there is an indication to the use of paclitaxel and carboplatin. Successive cohorts of patients will receive escalating doses of PF-05212384 in combination with paclitaxel and carboplatin, starting at a dose level determined to be the 60% of single agent MTD. The study will consist of two parts: the dose finding part (Part 1) and the expansion part (Part 2). During Part 1 patients with breast, NSCLC, ovary and endometrial, small cell lung cancer (SCLC) and Head and Neck (HNSCC) cancer will be enrolled. During Part 2, only patients with ovarian cancer will be enrolled. In Part 1, a 3+3 design is employed. Once the MTD of the combination is defined in Part 1, Part 2 is performed for a better definition of the safety profile, of the potential antitumor activity and of the pharmacodynamic effects of the combination; it will be conducted in at least 12 patients with ovarian cancer. Approximately 40 patients are expected to be enrolled in the study overall.
