Products
RB-601 (c-MET / EGFR bispecific nanobody ADC)
Bispecific nanobody-based ADC targeting c-MET and EGFR using site-specific conjugation to deliver a homogeneous DAR and an MMAE payload; cleared for IND in China and subject to first-in-human studies.
RB-164 (ROR-1 targeted ADC)
Fc-silenced ADC targeting ROR-1 with site-specific conjugation and a novel linker to deliver homogeneous DAR and enhanced stability; progressed into Phase I dose-escalation trials with IND clearances reported.
RB-201 (HER2 / TROP-2 bispecific ADC)
Bispecific ADC targeting HER2 and TROP-2 for tumors co-expressing these antigens; demonstrated superior efficacy versus monospecific ADCs in preclinical models and planned first-in-human Phase Ia/b clinical trial.
RB-203 (membrane Hsp70 monoclonal antibody and companion diagnostic)
Monoclonal antibody recognizing membrane Hsp70 that selectively accumulates in tumors expressing this biomarker; paired with a patented blood ELISA test to detect exosomal Hsp70 for tumor detection and response monitoring.
