A Study of LY2484595 on Pharmacokinetics in Healthy Participants
A Phase 1 Study to Evaluate the Safety and Tolerability of LY2484595 SDSD-PG Tablets and the Effect of CYP3A Inhibition by Ketoconazole on the Pharmacokinetics of LY2484595 in Healthy Subjects
This is a 2-part study. Part 1 is to determine the safety and tolerability in healthy participants of increasing daily doses of LY2484595 for 14 days to achieve a blood level of LY2484595 much higher than what is needed for therapy. The amount of study drug that reaches the bloodstream and the time it takes for the body to get rid of it will be determined. The effect of the study drug on factors in the blood related to cholesterol will be measured.
Part 2 is to determine how ketoconazole affects how much of the study drug, LY2484595, gets into the bloodstream and how long it takes to get rid of it. Information about any side effects that may occur will also be collected.
研究概览
详细说明
This study is a 2-part, multiple ascending dose (MAD) and drug drug interaction (DDI) study to evaluate the safety and tolerability and the effect of cytochrome P450 (CYP) 3A inhibition by ketoconazole on the pharmacokinetics of LY2484595 in healthy participants.
In the MAD portion (Part 1) of this study, participants in 4 cohorts (Cohorts A through D) will be randomized to receive either LY2484595 (5 ascending dose levels [100 to 1800 mg]) or placebo. Cohorts will have staggered starts ≥7 days from the previous cohort to allow for review of safety and tolerability. The total duration of Part 1 is approximately 13 weeks including screening.
Participants in Cohort A will participate in 2 periods separated by a washout period lasting ≥14 days. During Period 1, participants will receive the starting dose of LY2484595 (100 mg) or placebo once daily (QD) for 14 consecutive days. During Period 2, participants will receive the highest dose of LY2484595 (1800 mg) or placebo QD for 14 consecutive days. Participants will complete a follow-up visit ≥14 days after the last dose of study drug.
Participants in Cohorts B, C, and D will receive LY2484595 (300, 600, and 1200 mg LY2484595, respectively) or placebo QD for 14 consecutive days followed by a follow-up visit ≥14 days after last dose of study drug.
The DDI portion of this study (Part 2) will be open label and consist of 2 periods. The total duration of Part 2 is approximately 10 weeks. LY2484595 (100 mg) will be administered on Day 1 of Period 1 and on Day 5 of Period 2. In Period 2, ketoconazole (400 mg) will be administered QD for 14 consecutive days (13 days alone [Days 1 through 4 and 6 through 14] + 1 day with LY2484595 [Day 5]). There will be a ≥14-day washout period between dosing during Period 1 and Period 2. Participants will return for a follow-up visit ≥14 days after last dose of study drug.

Part 1: Number of Participants With 1 or More Adverse Events (AEs) or Any Serious AEs
大体时间:Part 1: Baseline through ≥14 days after last dose of study drug (≥Day 28)
|
The number of participants with 1 or more AEs is summarized cumulatively.
In addition, the number of participants with any serious AEs is summarized cumulatively.
A serious AE is defined as an event that results in death, initial or prolonged hospitalization, is life-threatening, leads to persistent or significant disability/incapacity, is associated with congenital anomaly/birth defect, or is considered significant by the investigator for any other reason.
A summary of serious and other non-serious AEs regardless of causality is located in the Reported Adverse Events module.

Pharmacokinetics: Maximum Observed Plasma Concentration (Cmax) of LY2484595

|
The geometric least squares (LS) means for the maximum observed plasma concentration (Cmax) of LY2484595 following administration of LY2484595 alone and with ketoconazole are reported.
Least squares means were calculated from an analysis of variance (ANOVA) model with a fixed effect for treatment and a random effect for participant.
The LS means for each treatment and the 90% confidence intervals (CI) for the difference in means were back transformed from the log scale to provide estimates of the geometric means and 90% CIs for the ratio of the geometric means (LY2484595 coadministered with ketoconazole and LY2484595 alone).
