Targeting the Glycan Signature: Oncofetal Chondroitin Sulfate as a Selective Vulnerability in Acute Myeloid Leukemia

MedXY Editorial Team•Mar 18, 2026•Clinical Updates

Oncofetal chondroitin sulfate (ofCS) is highly expressed in AML blasts and patient-derived xenografts (PDXs) but largely absent in healthy adult bone marrow and hematopoietic stem cells.
Anti-ofCS antibodies demonstrate rapid internalization,

a prerequisite for effective delivery of cytotoxic payloads via antibody-drug conjugates (ADCs).
In preclinical PDX models, anti-ofCS ADCs significantly prolonged survival with a favorable safety profile, avoiding the severe hematotoxicity typical of CD33- or CD123-targeted therapies.
This study identifies glycosaminoglycans as a new class of druggable targets in hematologic malignancies, potentially expanding treatment options for older or unfit patients.
