Human epidermal growth factor receptor 2, or HER2, is a gene that encodes a protein that promotes cell growth and differentiation. HER2 protein overexpression and gene amplification have been documented across multiple cancers. Previous targeting of HER2 has had a major impact on the subset of patients with HER2-expressing breast and gastric cancer, but there remains a significant amount of work to be done highlighted by a significant individual and global patient need.

Our lead product candidate, BDC-1001, currently advancing into a Phase 2 clinical trial, seeks to improve therapeutic outcomes for patients with HER2-positive colorectal, endometrial, gastroesophageal and metastatic breast cancer.

Range of Solid Tumors

Preclinical

IND-enabling activities

Our Myeloid Modulator Platform reawakens myeloid cells to attack tumor cells. We identified monoclonal antibodies that are capable of binding to and agonizing a novel cell surface protein (referred to as Dectin-2) on tumor-supportive macrophages. The activation of these macrophages results in the production of pro-inflammatory cytokines, consistent with the characteristics of tumor-destructive macrophages. Dectin-2 may have the potential to reprogram tumor-supportive macrophages into tumor-destructive macrophages to elicit a productive anti-tumor immune response.
