ClinicalTrials.gov Identifier:
NCT01263106
First received: December 16, 2010
Last updated: March 15, 2011
Last verified: March 2011
  Purpose

The primary aim of this study is to confirm that LY2216684 is not an inhibitor of CYP1A2 in vivo using theophylline as a probe substrate for the enzyme. Since LY2216684 has been observed to increase heart rate in some healthy subjects, this study will also assess heart rate when co-administered with theophylline.

  • Are persons who have previously completed or withdrawn from this study or any other study investigating LY2216684 within 6 months prior to screening.
  • Have an abnormality in the 12-lead ECG that, in the opinion of the investigator, increases the risks associated with participating in the study.
  • Have a history of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study medication; or of interfering with the interpretation of data.
