Guangdong Zhongsheng Pharmaceutical Co., Ltd (SHE: 002317) announced positive top-line results from two Phase III clinical studies evaluating onradivir in pediatric and adolescent influenza patients. The trials tested onradivir granules in children aged 2-11 versus Roche’s Tamiflu, and onradivir tablets in adolescents aged 12-17 versus placebo, addressing critical unmet needs in pediatric antiviral formulation and swallowing difficulty populations.

Positive efficacy + favorable safety
Strategic Rationale & Formulation Innovation
Pediatric-Focused Development: Both trials designed specifically to facilitate medication use for children, adolescents, and patients with swallowing difficulties—a historically underserved population in influenza treatment
Granule Formulation Advantage:Onradivir granules enable flexible dosing and ease of administration for young children unable to swallow capsules, directly competing with Tamiflu dry suspension in the pediatric market
Tablet Transition:Onradivir tablets for adolescents bridge the gap to adult formulations, supporting lifecycle management and patient continuum of care from childhood through adulthood
Competitive Context & Market Positioning
Factor
Strategic Implication
Tamiflu Head-to-Head
Onradivir granules demonstrated non-inferior/superior efficacy vs. Roche’s established standard of care
Pediatric Influenza Market
Significant commercial opportunity; children represent high-transmission population driving household prescribing
Formulation Differentiation
Granules address swallowing difficulties across age spectrum, including elderly and disabled populations
China Antiviral Landscape
Onradivir advances as domestic alternative to imported neuraminidase inhibitors, aligning with API localization priorities
Development & Commercial Outlook
Priority
Execution Plan
Regulatory Submission
NDA filing to NMPA based on Phase III data package
Formulation Strategy
Market granules for pediatric/swallowing-difficulty segments; tablets for adolescent/adult transition
Seasonal Positioning
Target influenza seasonality with pre-stocking and hospital formulary placement
Lifecycle Expansion
Potential exploration in influenza B and high-risk patient populations
Forward‑Looking Statements This brief contains forward‑looking statements regarding onradivir regulatory approval timelines, pediatric influenza market penetration, and competitive positioning against oseltamivir products. Actual results may differ due to NMPA review processes, pricing negotiations for pediatric antivirals, and seasonal influenza variability affecting commercial demand.-Fineline Info & Tech
