Frequently asked questions about LY3473329

What is LY3473329?

LY3473329 is an investigational small molecule developed by Eli Lilly and Company for lipoprotein disorders and renal insufficiency. It is a metabolic therapy being studied in adults with elevated lipoprotein(a) who are at high risk for cardiovascular events, and separately in people with impaired and normal renal function.

What is LY3473329 used for?

LY3473329 is being studied for lipoprotein disorder, specifically elevated lipoprotein(a) in adults at high risk for cardiovascular events, and for renal insufficiency. It is an investigational therapy and is not approved for any use. The Phase 2 study enrolled adults aged 40 years and older.

Who makes LY3473329?

LY3473329 is developed by Eli Lilly and Company, which trades on the New York Stock Exchange under the ticker LLY. Lilly is the sponsor of the clinical program evaluating the small molecule in lipoprotein disorder and renal insufficiency.

What phase is LY3473329 in?

LY3473329 is in Phase 2 development. The Phase 2 trial in adults with elevated lipoprotein(a) at high risk for cardiovascular events has completed, and a Phase 1 study in participants with impaired and normal renal function has also completed. The drug remains investigational.

What clinical trials is LY3473329 in?

LY3473329 has been studied in two completed trials. NCT05563246 was a Phase 2 study in adults with elevated lipoprotein(a) at high risk for cardiovascular events, enrolling 233 participants across the United States, Australia, Brazil, China, Germany, Hungary, Japan and the Netherlands. NCT05778864 was a Phase 1 study in participants with impaired and normal renal function, enrolling 47 people in the United States.

Is LY3473329 the same as [14C]-LY3473329?

Yes, [14C]-LY3473329 is an alternative designation for LY3473329. The bracketed carbon-14 label refers to a radiolabeled form used in study work, while LY3473329 is the compound itself, an investigational small molecule developed by Eli Lilly and Company for lipoprotein disorder and renal insufficiency.
