HER3 is a target that is overexpressed in various cancer types, such as non-small cell lung cancer and breast cancer and is closely associated with tumor metastasis and disease progression. Furthermore, HER3 expression is upregulated after frontline drug therapy, making it an adequate target for cancer treatment. MediLink's ADC candidate has demonstrated encouraging efficacy and safety in various preclinical tumor models through the utilization of MediLink's TMALIN® technology, and preliminary clinical data further supports the conceptual validation of this candidate.
