LONDON, UK I February 17, 2021 I Silence Therapeutics plc, AIM: SLN and Nasdaq: SLN (“Silence” or “the Company”), a leader in the discovery, development and delivery of novel short interfering ribonucleic acid (siRNA) therapeutics for the treatment of diseases with significant unmet medical need, today announced that it has started dosing subjects in the APOLLO Phase I clinical study of its wholly owned lead product candidate, SLN360, for the treatment of elevated Lipoprotein (a) – or Lp(a) – levels.
This first-in-human study is investigating the safety, tolerability, pharmacokinetic and pharmacodynamic response of SLN360 in people with elevated Lp(a) levels approximately ≥60 mg/dL. The APOLLO trial is a global, randomized, double-blind, placebo controlled, single-ascending and multiple-ascending dose study enrolling approximately 88 subjects total in up to nine cohorts.
Silence intends to report data from the single-ascending dose portion of the study in the second half of this year.
More information on the SLN360 APOLLO trial can be found here.
Silence’s wholly owned lead product candidate, SLN360, is a gene ‘silencing’ therapy – one that is designed to temporarily block a specific gene’s message that would otherwise trigger an unwanted effect. In this case, it aims to ‘silence’ LPA, a gene that tells the body to make a specific protein that is only found in Lp(a). By silencing LPA, the levels of Lp(a) are lowered, which in turn is expected to lower the risk of heart diseases, heart attacks and strokes.
Lipoprotein(a), known as Lp(a) for short, is a particle made by the liver, which consists of cholesterol, fats and proteins. Most people have some Lp(a) in their body, but about 1 in 5 people have high levels of Lp(a), because of a specific gene variation in their DNA. Most people are unaware if they have elevated Lp(a). People living with elevated Lp(a) have a higher risk of developing early heart disease, heart attacks and strokes. Most standard cholesterol tests do not currently include screening for Lp(a). Current medicines that are used to lower other lipid levels in the blood do not have a meaningful effect on Lp(a) and are less effective overall in people with high levels of Lp(a).
About Silence Therapeutics
Silence Therapeutics is developing a new generation of medicines by harnessing the body's natural mechanism of RNA interference, or RNAi, to inhibit the expression of specific target genes thought to play a role in the pathology of diseases with significant unmet medical need. Silence's proprietary messenger RNAi GOLD™ (GalNAc Oligonucleotide Discovery) Platform can be used to create siRNAs that precisely target and silence disease-associated genes in the liver, which represents a substantial opportunity. Silence's wholly owned product candidates include SLN360 designed to address the high and prevalent unmet medical need in reducing cardiovascular risk in people born with high levels of lipoprotein(a) and SLN124 designed to address iron loading anemias. Silence also maintains ongoing research and development collaborations with AstraZeneca, Mallinckrodt Pharmaceuticals, and Takeda, among others.
