  • Research summary

    The study drug, LY3473329 is a small molecule that interacts with low density lipoproteins (LDLs) responsible for producing the lipoprotein complex known as Lipoprotein A [Lp(a)]. High levels of Lp(a) have been linked with worsening cardiovascular disease outcomes. It is thought that LY3473329 will disrupt the formation of Lp(a), thus reducing the rate of heart disease in patients at risk.
    This trial is a phase 1, open-label, single dose study in healthy male participants. The study will consist of two parts.
    Part 1 of this study aims to determine how much of the study drug and its breakdown products get into the bloodstream, urine, faeces and/or expired breath following a single oral solution dose of LY3473329 (Dose 1), containing a small radio-labelled component (Dose 1R).
    Part 1 will have about 8 participants. Following a screening visit, participants who qualify for the study may continue with 1 in-clinic visit lasting a minimum of 15 days or a maximum of 30 days, as well as 1 follow-up telephone call about 7 days after discharge from the clinic.

    Part 2 will aim to compare the amount of Study Drug that gets into the bloodstream, urine and faeces when given by mouth and when given directly into the vein (intravenously). As such the study will involve a dose of oral non-radiolabelled LY3473329 (Dose 2), followed by administration of a radiolabelled IV dose of [14C]-LY3473329 (Dose 2R).

    Part 2 will have approximately 8 participants. Following screening, participants will have 1 in-clinic visit lasting 10 days, as well as 1 follow-up telephone call about 7 days after discharge from the clinic.
