Silence Therapeutics Reports Second Quarter 2026 Financial and Business Results
10 August 2026
LONDON, Silence Therapeutics plc, (Nasdaq: SLN), a global clinical-stage company developing novel siRNA (short interfering RNA) therapies, today reported its financial and business results for the second quarter ended June 30, 2026.
Business Highlights
Divesiran: First-in-class siRNA silencing TMPRSS6 for polycythemia vera (PV) and other blood disorders
| • | Presented follow-up data from the Phase 1 SANRECO trial at the European Hematology Association (EHA) 2026 Annual Congress in June 2026 demonstrating durable efficacy results and potential best-in-class profile for divesiran in PV. The EHA 2026 poster is available here. |
| • | Completed patient dosing in the Phase 2 SANRECO double-blind, placebo-controlled trial evaluating divesiran 6 mg/kg (Q6W and Q12W dosing intervals) in 48 phlebotomy-dependent PV patients in June 2026. |
| • | American Journal of Hematology published a preclinical study authored by Silence scientists exploring the potential of TMPRSS6 silencing as a therapeutic approach for myelodysplastic syndrome (MDS) in June 2026. You can read the publication here. |
SLN312 (AZD1705): Phase 1 siRNA silencing ANGPTL3 with a competitive profile for dyslipidemia
| • | Phase 1 results generated under the Company’s AstraZeneca collaboration were presented by AstraZeneca during a late-breaking oral presentation at the European Atherosclerosis Society (EAS) Congress in May. Results demonstrated a favorable safety profile and dose-dependent, durable reductions in ANGPTL3 protein levels as well as in atherogenic lipoproteins including LDL-C, Apo-B and non-HDL-C. The EAS 2026 presentation is available here. |
Pre-clinical pipeline updates:
| • | Generated additional preclinical data demonstrating the effect of SLN365 (GPR146) on lipids was reproduced and not altered by co-treatment with statin or ezetimibe. The program is well positioned for a potential IND filing in 2027. |
| • | Generated additional preclinical data for SLN098 (INHBE) in a diet induced obesity mouse model demonstrating reduced visceral fat and preservation of lean body mass. The program is well positioned for a potential IND filing in 2027. |
Second Quarter 2026 Financial Results
| • | Cash Position: Cash and cash equivalents were $72.1 million as of June 30, 2026. |
| • | R&D Expenses: Research and development (R&D) expenses were $9.1 million for the three months ended June 30, 2026, compared to $17.6 million for the three months ended June 30, 2025. The $8.4 million decrease is mainly due to the zerlasiran Phase 3 readiness being completed in 2025 as well as reduced personnel costs. |
| • | G&A Expenses: General and administrative (G&A) expenses were $4.7 million for the three months ended June 30, 2026, compared to $5.1 million for the three months ended June 30, 2025. |
| • | Net Loss: Net loss was $12.3 million, or $0.09 basic and diluted net loss per share for the three months ended June 30, 2026, compared to a net loss of $27.4 million, or $0.19 basic and diluted net loss per share for the three months ended June 30, 2025. |
| • | Total outstanding shares were 141,739,180 ordinary shares (including shares in the form of American Depositary Shares) as of June 30, 2026. |
