Anti-IGF1R (Robatumumab)-MC-MMAF ADC (ADC-W-1252)

This ADC product is comprised of an anti-IGF1R monoclonal antibody conjugated via a MC linker to MMAF. The MMAF is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, MMAF binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death.

 ADC Target

  • Name
  • IGF1R
  • Alternative Names
  • IGF1R; insulin-like growth factor 1 receptor; CD221; IGFIR; IGFR; JTK13; MGC18216; IGF-I receptor; soluble IGF1R variant 1; soluble IGF1R variant 2; insulin-like growth factor I receptor; MGC142170; MGC142172;
  • Target Entrez Gene ID
  • 3480
  • Overview
  • This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

  • Host animal
  • Human

 ADC Linker

  • Name
  • MC (maleimidocaproyl)
  • Description
  • Noncleavable linkers, is considered noncleavable-meaning linker cleavage, and payload release does not depend on the differential properties between the plasma and some cytoplasmic compartments. Instead, the release of the cytotoxic drug is postulated to occur after internalization of the ADC via antigen-mediated endocytosis and delivery to lysosomal compartment, where the antibody is degraded to the level of amino acids through intracellular proteolytic degradation.

 ADC payload drug

  • Name
  • MMAF
  • Description
  • Derived from Auristatin,are water-soluble dolastatin analogs of dolastatin 10. Dolastatin 10 belongs to dolastatin family and it can powerfully bind to tubulin, thus inhibiting polymerization mediated through the binding to the vinca alkaloid binding domain, and causes cell to accumulate in metaphase arrest.
