Silence Therapeutics plc (AIM:SLN and Nasdaq: SLN), 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, and Hansoh Pharmaceutical Group Company Limited ("Hansoh Pharma", 3692.HK), one of the leading biopharmaceutical companies in China, today announced a collaboration to develop siRNAs for three undisclosed targets leveraging Silence's proprietary mRNAi GOLD™ platform.

Under the terms of the agreement, Hansoh will have the exclusive option to license rights to the first two targets in Greater China, Hong Kong, Macau and Taiwan following the completion of phase 1 studies. Silence will retain exclusive rights for those two targets in all other territories. Silence will be responsible for all activities up to option exercise and will retain responsibility for development outside the China region post phase 1 studies.

Hansoh will also have the exclusive option to license global rights to a third target at the point of IND filing. Hansoh will be responsible for all development activities post option exercise for the third target.

Hansoh will make a $16 million upfront payment and Silence is eligible to receive up to $1.3 billion in additional development, regulatory and commercial milestones. Silence will also receive royalties tiered from low double-digit to mid-teens on Hansoh net product sales.

Mark Rothera, President and Chief Executive Officer of Silence Therapeutics, said: "We believe Hansoh's extensive clinical development and commercialization experience in China make them an ideal partner. This collaboration is a good example of our hybrid model in action, balancing proprietary and partnered programs to maximize the substantial opportunity of our mRNAi GOLD™ platform for targeting disease associated genes in the liver. The Hansoh partnership enables us to move two new proprietary programs forward subsidized by non-dilutive capital while also gaining access to the second largest pharmaceutical market globally. We look forward to discussing this deal and our broader pipeline in more detail at our upcoming R&D Day on October 21st in New York City."

Eliza Sun, Executive Director of the Board of Hansoh Pharma, said: "We are excited to partner with Silence, a pioneer in siRNA therapeutic development with decades of scientific and technical experience. As one of the largest biopharma in China, Hansoh strives to partner with innovative companies globally to build out and advance our robust pipeline spanning across multiple therapeutic areas. We see substantial opportunity in Silence's mRNAi GOLD™ platform to develop and bring better precision-based medicines to patients across China and worldwide."

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 need. 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 Takeda, among others.
