A Study of LY2216684 and Theophylline in Healthy Subjects
This study has been completed.
Information provided by:
Eli Lilly and Company
First received: December 16, 2010
Last updated: March 15, 2011
Last verified: March 2011
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.

||Effect of LY2216684 on the Pharmacokinetics of Theophylline in Healthy Subjects
Primary Outcome Measures:
- Pharmacokinetics, concentration maximum (Cmax) of Theophylline [ Time Frame: Predose 1,2,3,4,6,8,12,24,48,and 72 hours post administration of theophylline on days 1 and 3. ] [ Designated as safety issue: Yes ]
- Pharmacokinetics, time to concentration maximum (tmax) of Theophylline [ Time Frame: Predose 1,2,3,4,6,8,12,24,48,and 72 hours post administration of theophylline on days 1 and 3. ] [ Designated as safety issue: Yes ]
- Pharmacokinetics, area under the curve (AUC) of Theophylline [ Time Frame: Predose 1,2,3,4,6,8,12,24,48,and 72 hours post administration of theophylline on days 1 and 3. ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Change in Heart Rate [ Time Frame: Baseline, day 1 and day 3 ] [ Designated as safety issue: Yes ]
