Abstract

A method of reducing the serum Lp(a) concentration in a subject is disclosed. A suspension of small, unilamellar vesicles composed primarily of phospholipids, similar in nature to those of egg phosphatidylcholine, is administered parenterally to a subject having or at risk for developing a disease condition associated with an elevated serum Lp(a) concentration. In the method, liposomes are infused over an extended period of time of at least several weeks, until a significant drop in serum Lp(a) concentration is observed.
