Investment summary

Silence Therapeutics is a developer of RNA-based therapeutics with some of the foundational intellectual property in the space. The value of its platform has been highlighted with recent licensing deals with Mallinckrodt to develop a complement inhibitor, with Takeda to research undisclosed targets, and recently with AstraZeneca to research cardiovascular, renal, metabolic and respiratory targets. This is in addition to the company’s internal pipeline; SLN124 and SLN360 both recently began enrolling patients into Phase I studies.
