Hepatobiliary (HB) safety of eltrombopag administered after carboplatin+paclitaxel (Carb+Pac) in patients (pts) with solid tumors

e20667 Background: Eltrombopag is an oral, small molecule, non-peptide, TPO-receptor agonist studied for the treatment of thrombocytopenia (TCP) due to various causes, including chemotherapy (CT)-induced TCP and is approved for the treatment of chronic ITP in the US. Since eltrombopag is excreted primarily through the liver and liver function is an important safety parameter, HB lab values and AEs were analyzed in a double-blind, placebo (pbo)-controlled, multicenter ph II study. Methods: The safety of eltrombopag was evaluated in adults with advanced solid tumors (mainly NSCLC and ovarian). Pts received up to 8 cycles of Carb (AUC 5–6 IV) + Pac (175–225 mg/m2 IV), both administered on day 1 q 21 days. 183 pts were randomized to eltrombopag 50, 75, 100mg, or pbo (1:1:1:1). Eltrombopag or pbo were taken from Day 2 - 11 in each cycle of CT. Results: Baseline characteristics, prior medical conditions and number of CT cycles during the study were similar between the treatment groups. At baseline, one pt repor...
