a study of abt-165 in subjects with solid tumors

Conditions: Advanced Solid Tumors

Summary: this is a phase 1/1b open-label study evaluating the safety, pharmacokinetics (pk), and preliminary efficacy of abt-165 when administered as monotherapy and in combination with paclitaxel or 5-fluoruracil, folinic acid and irinotecan (folfiri) or abbv-181 with/without paclitaxel in subjects with advanced solid tumors. enrollment to cohorts a, b were completed and for cohorts c and d are recruiting.
