Core Technology Platforms
Simcere Zaiming’s pipeline originates from three self‑developed platforms:

|---|---|---|---|
| T‑Cell Engager (TCE) | Multi‑specific antibodies | Highly tumor‑specific T‑cell activation, extremely low non‑tumor binding → broader therapeutic window | Solid tumors, hematologic malignancies |
| ADC | Antibody‑drug conjugates | More specific tumor targets, improved linkers/payloads; novel payloads to overcome resistance | Oncology (multiple targets) |
| Degrader | Molecular glue + antibody‑degrader hybrids | Oral molecular glue degraders for “undruggable” targets; antibody‑enhanced degradation for tumor specificity | Protein degradation |
Global Competitiveness: These platforms commanded the highest licensing deal values in 2025, validating their first‑in‑class potential and industrial scalability.
