A Phase 1 interventional study of Levetiracetam and Keppra® in Healthy, sponsored by Teva Pharmaceuticals USA. Completed at 1 site in Canada. Open to participants aged 18 Years to 55 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2009-09-11.
Sponsored by Teva Pharmaceuticals USA (part of Teva Pharmaceutical Industries, Ltd.) · Phase 1 and Interventional
The objective of this study is to compare the rate and extent of absorption of a test formulation of Levetiracetam tablets versus the reference Keppra® administered as a 1 x 750 mg tablet under fed conditions.
Criteria for Evaluation: FDA Bioequivalence Criteria
Statistical Methods: FDA bioequivalence statistical methods

The record gives a start of Nov 2005, a primary completion of Nov 2005 and a completion of Nov 2005. It does not say whether these dates are actual or estimated.
Results were first posted in Aug 2009, 3 years 9 months after primary completion.
