SBT LeadTherapeutic sdAb: SBT-100

SBT-100 is a bi-specific KRAS/STAT3 inhibitor

  • Nanomolar affinity to KRAS/STAT3 (the most common mutations)
  • Internalizes into cancer cells
  • Crosses cell membrane & BBB (Blood Brain Barrier)
  • In vivo & In vitro efficacy data against KRAS & STAT3 cancers
  • Short serum half-life but long biological half-life
  • No toxicity observed for 28 days
  • Pre-IND stage (2Q20)
  • Potential therapeutic for a large range of cancers
    • In various malignancies (pancreatic cancer and glioblastomas) KRAS & STAT3 work together to produce malignant transformation.
    • KRAS can promote IL-6 production in the tumor microenvironment resulting in STAT3 activation in cancer cells.
    • In some clinical situations KRAS via its downstream target can phosphorylate the serine residue of STAT3 to further potentiate its activation.
    • Targeting both KRAS & STAT3 minimizes the potential for drug resistant cancer cells from developing.
    • STAT3 plays a critical role in KRAS-induced pancreatic tumorigenesis.
