CDH17 (Cadherin-17) Drug Discovery Landscape & Assay Solutions

Market Intelligence, Clinical Progress, and High-Purity Reagents for Gastrointestinal Malignancy Development.

CDH17 (Cadherin-17, UniProt Q12864) is a membrane glycoprotein containing three cadherin domains (Cadherin 1, 2, 3) that mediates calcium-dependent cell adhesion. It is highly expressed in gastrointestinal (GI) malignancies such as gastric and colorectal cancers, with restricted expression in normal tissues, making it an attractive target for antibody-drug conjugates (ADCs), bispecific T-cell engagers, CAR-T therapy, and diagnostic imaging. Key naturally occurring mutations include rs2243518, rs1131829, and rs1051623 (dbSNP), which may influence protein function or immunogenicity.

Global Clinical Landscape & Future Outlook

The race for CDH17 (Cadherin-17) therapeutics is intensifying, with major players shifting focus from traditional mAbs to Antibody-Drug Conjugates (ADCs), bispecific T-cell engagers, and CAR-T cell therapies. As an essential target in gastrointestinal (GI) malignancies, particularly gastric and colorectal cancers, CDH17 offers highly restricted normal tissue expression, minimizing on-target off-tumor toxicity. First-generation therapies are entering preclinical and early clinical stages, while next-wave R&D targets epitope-engineered biologics with improved tumor-to-normal tissue differentiation, optimal affinity tuning for solid tumor penetration, and combination strategies with immune checkpoint inhibitors or other GI targets (CLDN18.2, CEACAM5, GUCY2C). The pipeline is increasingly focused on ADCs (about 40%) and CAR-T (about 50%), with bispecifics and diagnostic imaging also gaining traction.

CDH17 Molecular Features

Based on UniProt Q12864, CDH17 contains three extracellular cadherin domains (Cadherin 1, residues 56-156; Cadherin 2, residues 169-270; Cadherin 3, residues 282-383), a transmembrane region (residues 409-429), and a cytoplasmic tail. Known single-nucleotide polymorphisms include rs2243518 (missense), rs1131829 (missense), and rs1051623 (missense), which may affect protein stability or epitope presentation. These features are critical for designing antibodies with selective domain binding and for understanding potential immunogenicity in clinical development.
