Huadong Medicine and Shian Biotech Advance siRNA Obesity Therapy to Preclinical Stage

Huadong Medicine Co., Ltd (SHE: 000963) announced a key milestone in its strategic collaboration with Suzhou Shian Biotechnology Co., Ltd., advancing their jointly developed siRNA therapy for obesity and metabolic diseases into formal preclinical development. The partnership, established in early 2025, has successfully completed preclinical candidate compound (PCC) identification for a novel weight-loss mechanism, positioning the asset for IND-enabling studies and potential global licensing opportunities.

Partnership Structure & Milestone

ElementDetail
CompaniesHuadong Medicine (SHE: 000963) × Suzhou Shian Biotechnology
Partnership InceptionEarly 2025
Therapeutic FocusObesity and non-alcoholic steatohepatitis (MASH)

Technology Platform & Strategic Rationale

FeaturesiRNA ApproachStrategic Value
MechanismNovel weight-loss target via RNA interferenceDifferentiation from GLP-1 receptor agonist saturation
DurationPotential for quarterly or bi-annual dosing vs. weekly injectionsImproved patient compliance, reduced healthcare burden
MASH SynergyDual metabolic/liver benefit pathwayAddresses comorbidity of obesity and fatty liver disease
Next-Generation PositioningPost-GLP-1 era innovationCaptures market seeking alternatives to incretin therapy
  • Collaboration Logic: Huadong Medicine contributes clinical development expertise, regulatory resources, and China commercial infrastructure; Shian Biotech provides proprietary siRNA platform and novel target biology

Market Context & Competitive Landscape

FactorMarket Implication
Global Obesity MarketProjected $100 billion by 2030; GLP-1 drugs (Ozempic, Wegovy) dominate but face adherence and muscle-loss challenges
siRNA Metabolic PipelineEmerging class with Arrowhead, Alnylam, and Ionis advancing candidates; first-mover advantage in specific targets critical
China Obesity Burden>50% of adults overweight/obese; domestic innovation prioritized under Healthy China 2030
MASH Opportunity$35 billion projected market with no approved pharmacotherapies; siRNA offers disease-modifying potential
Licensing PotentialShian’s ex-territory fee structure indicates expectation of global Big Pharma partnership for US/EU markets
