Collaborator:
Genentech
Information provided by (Responsible Party):
AbbVie ( AbbVie (prior sponsor, Abbott) )
ClinicalTrials.gov Identifier:
NCT00481091
First received: May 30, 2007
Last updated: May 19, 2014
Last verified: May 2014
  Purpose

The Phase 1 portion of the study will evaluate the pharmacokinetic profile and safety of ABT-263 under two different dosing schedules with the objective of defining the dose limiting toxicity and maximum tolerated dose. The Phase 2a portion of the study will evaluate ABT-263 at the defined recommended Phase 2 dose to obtain additional safety information and a preliminary assessment of efficacy. The Extension Study portion will allow active subjects to continue to receive ABT-263 for up to three years after the last subject transitions with less frequent study evaluations.
