InnoCare Pharma Limited (SHA: 688428, HKG: 9969) announced that its self-developed VAV1-targeting molecular glue degrader, ICP-538, has received clinical trial approval from the Center for Drug Evaluation (CDE) of China’s NMPA. The oral, highly potent degrader targets refractory autoimmune diseases including inflammatory bowel disease (IBD), systemic lupus erythematosus (SLE), and multiple sclerosis (MS), marking a first-in-class entry into China’s autoimmune pipeline.

Company
InnoCare Pharma (SHA: 688428, HKG: 9969)
Agency
CDE/NMPA (China)
Asset
ICP-538 – VAV1-targeting molecular glue degrader
Approval
Phase I clinical trial authorization
Global Status
Second VAV1 degrader worldwide to enter trials; first in China
Current Market
No approved VAV1-targeted drugs globally
Technology Platform & Mechanism of Action
Drug Class:Molecular glue degrader – Next‑generation protein degradation technology
Target:VAV1 (Vav guanine nucleotide exchange factor 1) – Critical signaling node downstream of T-cell and B-cell receptors
Mechanism:
Forms ternary complex between CRBN E3 ubiquitin ligase and VAV1 protein
Induces rapid, potent, dose-dependent VAV1 degradation via proteasome pathway
Delivery:Oral administration – Potential convenience advantage over injectable biologics
Selectivity: Highly specific for VAV1 vs. other VAV family members
Target Indications & Autoimmune Focus
Disease
Unmet Need
Strategic Rationale
Inflammatory Bowel Disease (IBD)
Limited oral options; biologic fatigue common
T/B-cell modulation via VAV1 degradation
Systemic Lupus Erythematosus (SLE)
High disease burden; steroid dependence
Potential for disease-modifying therapy
Multiple Sclerosis (MS)
Progressive forms underserved
Neuroinflammation targeting through immune cell modulation
Competitive Landscape & Strategic Positioning
First-Mover Advantage: As the second VAV1 degrader globally and first in China, ICP-538 secures regulatory and clinical data leadership in the world’s second-largest pharmaceutical market.
Molecular Glue Differentiation: Unlike traditional kinase inhibitors or biologics, protein degraders offer catalytic mechanism (sub‑stoichiometric target elimination) and potential for improved efficacy in resistant populations.
InnoCare Platform Validation: ICP-538 advances InnoCare’s protein degradation pipeline beyond oncology (BTK inhibitor orelabrutinib) into immunology, demonstrating platform versatility and expanding addressable market.
Autoimmune Market Scale: China’s autoimmune disease therapeutics market is projected to exceed $15 billion by 2030, with significant unmet need in IBD and SLE where oral small molecules are limited.

Forward‑Looking Statements This brief contains forward‑looking statements regarding ICP-538 clinical development in autoimmune diseases, VAV1 target validation, and InnoCare Pharma’s protein degradation platform expansion. Actual results may differ due to early‑stage clinical risks, competitive dynamics in the molecular glue space, and regulatory requirements for novel degrader mechanisms.-Fineline Info & Tech
