| Main Objective: To evaluate the efficacy of oral SB-497115-GR at doses of 50, 75, and 100 mg compared with placebo in cycle 2 of carboplatin/paclitaxel chemotherapy, administered to subjects with an advanced solid tumour.;Secondary Objective: •Safety and tolerability of oral SB-497115-GR when administered to subjects receiving multiple cycles of carboplatin/paclitaxel chemotherapy. •Pharmacodynamic effect of SB-497115-GR on platelet count and function when administered to subjects receiving multiple cycles of carboplatin/paclitaxel chemotherapy. •Efficacy of SB-497115-GR at doses of 50, 75, and 100 mg in the first cycle and beyond the second cycle of carboplatin/paclitaxel chemotherapy. •Population PK profile of oral SB-497115. •To assess dose intensity of carboplatin/paclitaxel chemotherapy (percent of intended dose delivered) administered to the subjects who are also treated with oral SB-497115-GR. •Incidence and severity of thrombocytopenia-related adverse events (AEs) in subjects receiving multiple cycles of carboplatin/paclitaxel for the treatment of an advanced solid tumor who are also treated with oral SB-497115-GR. ;Primary end point(s): The primary endpoint is the change in platelet count from day 1 in cycle 2 (baseline) to cycle 2 nadir. | — |
