  "id": "MLC-T-ONC-015049",
  "term": "mecbotamab vedotin",
  "field": "Oncology and biomedicine",
  "definition": "An antibody-drug conjugate (ADC) composed of a conditionally active biologic (CAB) antibody against AXL receptor tyrosine kinase (AXL; UFO) conjugated to an as of yet undisclosed cytotoxic agent, with potential antineoplastic activity. Upon administration of mecbotamab vedotin, the anti-AXL antibody becomes activated through an as of yet not fully elucidated process only under the unique microphysical conditions that are present in the tumor microenvironment (TME) as a result of the glycolytic metabolism of cancer cells, and not in the microenvironment of normal, healthy tissues. Upon selective binding to AXL-expressing tumor cells and internalization, the cytotoxic agent kills the tumor cells through an as of yet undisclosed mechanism of action (MoA). AXL, a member of the TAM (TYRO3, AXL and MER) family of receptor tyrosine kinases normally expressed on many normal, healthy cells and overexpressed by many tumor cell types, plays a key role in tumor cell proliferation, survival, invasion and metastasis; its expression is associated with drug resistance and poor prognosis. The CAB antibody allows for efficient and reversible binding to AXL-expressing tumor cells under conditions that are present only in the TME, thereby maximizing efficacy while minimizing toxicity by avoiding activation and thus binding of the antibody to normal, healthy AXL-expressing cells under normal conditions.",
