5 November 2021

LONDON, 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 a leading healthcare focused investment firm, Frazier Life Sciences Public Fund, purchased approximately $20 million of existing ordinary shares in Silence and is now a 3% shareholder in the Company.

Albert Cha, M.D., Ph.D., Managing Partner of Frazier Life Sciences, said: “Frazier Life Sciences is excited for the prospects for Silence’s RNA interference platform technology and the potential for the Company’s growth, given its promising pipeline and the noteworthy success other companies have demonstrated with RNA interference programs.”

Mark Rothera, President and Chief Executive Officer of Silence, said: “Frazier has a track record of partnering with science-driven healthcare businesses, and we are very pleased to welcome them as an important new shareholder in Silence. This comes at an exciting time for the Company as we progress two important, wholly owned clinical stage programs and rapidly expand our pre-clinical pipeline leveraging our mRNAi GOLD™ platform.”

Craig Tooman, Chief Financial Officer of Silence, said: “A key objective of our decision to delist from AIM and focus our efforts on Nasdaq was to attract institutional healthcare funds like Frazier. This is exactly what we envisioned, and we look forward to continuing to expand our global shareholder base.”

Silence’s proprietary mRNAi GOLD™ platform can be used to create siRNAs (short interfering RNAs) 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 anemia conditions. Silence also maintains ongoing research and development collaborations with AstraZeneca, Mallinckrodt Pharmaceuticals, and Hansoh Pharma, among others.
