Topline results from the phase 1 APOLLO study of SLN360, a short interfering ribonucleic acid (siRNA) targeting lipoprotein(a), showed it significantly reduced Lp(a) in a dose-dependent manner from 46% to up to 98%.
Reductions of up to 81% were maintained out to 150 days, according to a release from the developer of the drug, Silence Therapeutics.
High Lp(a) affects about one in five people worldwide and is a genetic risk factor for cardiovascular disease. There are no approved medications that selectively lower Lp(a), and levels cannot be significantly modified through lifestyle changes or any approved medications.
SLN360 is a siRNA that is designed to lower Lp(a) production by using the body’s natural process of RNA interference to target and silence messenger RNA transcribed from the LPA gene in liver cells.
The first-in-human APOLLO trial evaluated 32 patients with serum Lp(a) concentrations of at least 150 nmol/L and no cardiovascular disease who received a single subcutaneous dose of SLN360 (30 mg, 100 mg, less than or equal to 300 mg, or less than or equal to 600 mg) or placebo and were followed for up to 150 days.
No clinically important safety concerns were identified, although low-grade adverse events at the injection site occurred, most prominently at the highest dose, according to the company.
Study follow-up has been extended to 1 year. Patient enrollment continues in the multiple-ascending dose portion of the phase 1 study in patients with high Lp(a) and a confirmed history of stable atherosclerotic cardiovascular disease, the company statement notes.
Detailed results from APOLLO will be presented in a late-breaking clinical trials session at the American College of Cardiology Annual Scientific Session on April 3 by principal investigator Steven E. Nissen, MD, Cleveland Clinic.
