A Single Dose Study of LY3023703 in Healthy Participants

A Single-Dose, Dose-Escalation Study to Evaluate the Safety and Tolerability of LY3023703 in Healthy Subjects

This is a phase I study of LY3023703 in healthy participants. The purposes of this study are to look at safety, how well the study drug is tolerated, how much of the study drug gets into the blood stream, and how long it takes the body to get rid of it when given to humans. Information about any side effects that may occur will also be collected. Participants will remain in the study for approximately 3 months. This study is for research purposes only and is not intended to treat any medical condition.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With One or More Drug Related Adverse Events (AEs) or Any Serious AE	AEs that were considered possibly related to study drug, in the opinion of the investigator, were reported. A summary of serious and all other non-serious AEs, regardless of possible study drug relatedness, is located in the Reported Adverse Events module.	Baseline up to Day 7 post-dose

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics: Maximum Concentration (Cmax) of LY3023703		Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 8 and 12 hours, post-dose
Pharmacokinetics: Area Under the Concentration Curve (AUC) of LY3023703	Area under the concentration time curve from the time of dosing to the time of the last observation.	Day 1: pre-dose, 0.25, 0.5, 1, 2, 4, 8 and 12 hours, post-dose
Pharmacodynamics: Percent Change From Baseline of ex Vivo Whole Blood Prostaglandin E (PGE) Synthesis After Lipopolysaccharide (LPS) Stimulation	Percent change from baseline of PGE synthesis=(postdose PGE synthesis-baseline PGE synthesis)/baseline PGE synthesis*100, where the unit of measure for PGE synthesis is nanograms per milliliter (ng/ml).	Baseline, 0.5 hours (h), 1 h, 2 h, 8 h, 24 h, and 144 h post-dose
Pharmacodynamics: Percent Change From Baseline of Urinary Excretion of Prostaglandin E(2) Metabolite (PGEM)	Urinary excretion of PGEM, after correcting for urinary creatinine. PGEM was corrected for urinary creatinine by dividing the picograms per milliliter (pg/mL) of metabolite excreted in urine by the concentration of creatinine [milligrams per milliliter (mg/mL)] in urine. Percent change from baseline of urinary excretion of PGEM=(mg creatinine per pg of metabolite excreted in urine postdose-mg of creatinine per pg of metabolite excreted at baseline)/mg of creatinine per pg of metabolite excreted at baseline*100.	Baseline, 0 to 2 hours (h), 2 to 4 h, 4 to 6 h, 6 to 12 h, and 12 to 24 hours post-dose
Pharmacodynamics: Percent Change From Baseline of Urinary Excretion of Prostacyclin Metabolite (PGIM)	Urinary excretion of PGIM, after correcting for urinary creatinine. PGIM was corrected for urinary creatinine by dividing the picograms per milliliter (pg/mL) of metabolite excreted in urine by the concentration of creatinine [milligrams per milliliter (mg/mL)] in urine. Percent change from baseline of urinary excretion of PGIM=(mg creatinine per pg of metabolite excreted in urine postdose-mg of creatinine per pg of metabolite excreted at baseline)/mg of creatinine per pg of metabolite excreted at baseline*100.	Baseline, 0 to 2 hours (h), 2 to 4 h, 4 to 6 h, and 6 to 12 h post-dose
Pharmacodynamics: Percent Change From Baseline of Urinary Excretion of Thromboxane A Metabolite (TXAM)	Urinary excretion of TXAM, after correcting for urinary creatinine. TXAM was corrected for urinary creatinine by dividing the picograms per milliliter (pg/mL) of metabolite excreted in urine by the concentration of creatinine [milligrams per milliliter (mg/mL)] in urine. Percent change from baseline of urinary excretion of TXAM=(mg creatinine per pg of metabolite excreted in urine postdose-mg of creatinine per pg of metabolite excreted at baseline)/mg of creatinine per pg of metabolite excreted at baseline*100.	Baseline, 0 to 2 hours (h), 2 to 4 h, 4 to 6 h, and 6 to 12 h post-dose
