Condition(s) targeted: Major Depressive Disorder

Intervention: LY2216684 (Drug); Theophylline (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Eli Lilly and Company

Official(s) and/or principal investigator(s):
Call 1-877-CTLILLY (1-877-285-4559) or 1-317-615-4559 Mon - Fri 9 AM - 5 PM Eastern time (UTC/GMT - 5 hours, EST), Study Director, Affiliation: Eli Lilly and Company


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.

Clinical Details

Official title: Effect of LY2216684 on the Pharmacokinetics of Theophylline in Healthy Subjects

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Pharmacokinetics, concentration maximum (Cmax) of Theophylline

Pharmacokinetics, time to concentration maximum (tmax) of Theophylline

Pharmacokinetics, area under the curve (AUC) of Theophylline

Secondary outcome: Change in Heart Rate
