A Pharmacokinetic Study of the Coadministration of LY2216684 With Sertraline

• Status: Completed
• Trial end date: 2011-01-01
• Target enrollment: 0
• Participant gender: All

Summary

LY2216684 is being studied as adjunctive treatment for major depressive disorder (MDD) in participants who are partial responders to selective serotonin reuptake inhibitors (SSRIs). Sertraline is a medication that is widely used to treat MDD and is a known substrate of cytochrome P450s (CYP450s), including CYP450 2D6 (CYP2D6), CYP450 2C19 (CYP2C19), CYPP450 3A4 (CYP3A4), and a modest inhibitor of CYP2D6. Based on the diversity of hepatic metabolic clearance pathways for LY2216684 and its elimination by the kidney, it is expected that CYP2D6 inhibition by sertraline will not result in a substantial change in the pharmacokinetic (PK) profile of LY2216684. LY2216684 is only known to be a moderate inhibitor of CYP2C19, so it is unlikely that coadministration of sertraline with LY2216684 will result in a clinically meaningful change in the PK of sertraline. This study is being conducted to test these hypotheses.

• Have normal blood pressure and pulse rate (supine position and standing) as determined by the investigator.

• Are reliable and willing to be available for the duration of the study and willing to follow study procedures.

• Provided written informed consent approved by Lilly and the institutional review board (IRB) governing the site.

Exclusion Criteria:

• Are currently enrolled in, or discontinued within the last 30 days from, a clinical trial involving an investigational drug or device, or off-label use of a drug or device other than the study drug used in this study, or are concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study.

• Have known allergies/intolerance to LY2216684, sertraline, or related compounds.

• Are persons who previously completed or discontinued from this study, or any other study investigating LY2216684 within 6 months prior to screening.

• Have a clinically significant abnormality in the 12-lead electrocardiogram (ECG) as determined by the investigator.

• Have significant history of or current cardiovascular (including dysrhythmias), 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.

• Have a history of seizure disorders.

• Have a history or presence of the signs and/or symptoms of hyponatremia.

• Have a history or presence of the signs and/or symptoms of hyperthyroidism as determined by an abnormal thyroid stimulating hormone (TSH) at screening.
