By Fineline Cube Changchun High & New Technology Industries (Group) Inc. (SHE: 000661) announced it has received approval from China’s National Medical Products Administration (NMPA) to initiate clinical studies for GenSci161, a novel fully human bispecific antibody targeting interleukin-1 (IL-1) for the treatment of endometriosis and moderate-to-severe hidradenitis suppurativa.
Drug Profile & Innovation
| Parameter | Detail |
|---|---|
| Molecule Type | Fully human bispecific antibody |
| Targets | IL-1α and IL-1β (dual inhibition) |
| Mechanism | Neutralizes IL-1α/β without binding to endogenous IL-1RA |
| Platform | OmniMab ultra-long-acting multispecific antibody platform |
| Dosing Interval | Subcutaneous administration every 8-12 weeks |
| Key Advantage | Preserves body’s intrinsic regulatory mechanisms |
Mechanism of Action
Dual IL-1 Targeting
- Primary Targets: Simultaneously inhibits IL-1α and IL-1β subtypes
- Downstream Effect: Blocks activation of inflammatory signaling pathways
- Selectivity: Does not interfere with endogenous IL-1 receptor antagonist (IL-1RA)
- Physiological Preservation: Maintains natural anti-inflammatory regulatory mechanisms
Extended Half-Life Technology
- Platform: Proprietary OmniMab Fc engineering technology
- Dosing Convenience: 8-12 week subcutaneous dosing intervals
- Patient Benefit: Reduced treatment burden compared to frequent dosing regimens
- Compliance Advantage: Long-acting profile supports chronic disease management
Target Indications
Endometriosis
- Prevalence: Affects approximately 10% of reproductive-age women globally
- Current Treatment: Limited options with significant side effects
- Unmet Need: Chronic inflammatory condition requiring long-term systemic therapy
- Market Opportunity: Large underserved patient population with high disease burden
Moderate-to-Severe Hidradenitis Suppurativa
- Prevalence: Chronic inflammatory skin disease affecting 1-4% of population
- Current Standard: Biologics like adalimumab approved but with limitations
- Treatment Gap: Need for more effective and convenient long-term options
- Commercial Potential: Premium pricing opportunity in dermatology biologics market
