A First-in-Human Study of LY3009385 in Healthy Participants

Eli Lilly and Company40 enrolled

Overview

The main purpose of this study is to determine the safety of LY3009385 in healthy participants. The study drug is given as a single dose, by injections under the skin. Side effects will be documented. This study is approximately 28 days not including screening. Screening is required within 28 days prior to the start of the study.

This is a single ascending dose study that examines the safety and tolerability, pharmacokinetics (PK), and pharmacodynamic (PD) effects of single doses of LY3009385 administered subcutaneously to healthy participants. The planned dose levels are 0.3, 1, 3, 9, 27, and 54 milligrams (mg). Within each dose level, participants are randomized to receive either LY3009385 or Placebo. Adjustments to the dose levels were permitted after review of emerging safety, PK, and glycemic data. The actual LY3009385 dose levels tested during this study were 0.3, 1, 3, 9, 22, and 54 mg.

Outcomes

Primary Outcomes

Number of Participants With One or More Drug-related Adverse Events (AEs) or Any Serious AEs

The number of participants with 1 or more AEs assessed as related to the study drug and is summarized cumulatively. In addition, the number of participants with 1 or more 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 adverse events regardless of causality is located in the Reported Adverse Events module.

Time frame: Baseline through Day 28

Secondary Outcomes

Pharmacokinetics: Area Under the Concentration Curve (AUC) of LY3009385

LY3009385 exposure in terms of AUC from time 0 extrapolated to infinity (AUC\[0-inf\]) is summarized.

Time frame: Predose through Day 28

Pharmacokinetics: Maximum Concentration (Cmax)

The maximum observed plasma concentration (Cmax) of LY3009385 is summarized.

Time frame: Predose through Day 28

Change in Level of Blood Glucose Before and After a Standard Meal

The effect of LY3009385 on postprandial blood glucose was evaluated. Change from baseline area under the glucose concentration-time curve from time 0 to 6 hours after participants started eating a standardized breakfast (mixed-meal tolerance test) was calculated and summarized by treatment arm.

Time frame: Baseline, Day 5, and Day 14

Change in Level of C-peptide Before and After a Standard Meal

The effect of LY3009385 on postprandial c-peptide was assessed. Change from baseline area under the c-peptide concentration-time curve from time 0 to 4 hours after participants started eating a standardized breakfast (mixed-meal tolerance test) was calculated and summarized by treatment arm.
