Drug Profile & Mechanism of Action
- Mechanism: CD3‑targeted mAb that modulates T‑cell activation and preserves pancreatic beta‑cell function, delaying autoimmune destruction
- Clinical Significance: Addresses Stage 2 T1D (presymptomatic phase with autoantibodies and dysglycemia), offering a 14‑day intravenous infusion course that can delay insulin dependence by 32.5 months vs. placebo (median)
- Unmet Need: No approved therapies previously existed in EU to modify T1D progression; patients progress inevitably to insulin dependence
