Description

Clarification of Nomenclature

The term "LCR47" does not align with established naming conventions for antibodies. Antibodies are typically designated by:

  • Target antigen (e.g., CD47)

  • Clone number (e.g., Hu5F9-G4, B6H12)

  • Developmental code (e.g., AK117, CC-90002)

Potential misinterpretations include:

  • Typographical errors (e.g., "LCR47" vs. "CD47")

  • Misreporting of clone names (e.g., CC2C6, M054)

Hu5F9-G4Yes (AML/NHL)HighYes (rituximab, cetuximab)
AK117Yes (solid tumors)NoneYes (AK112 anti-PD-1/VEGF)
CC-90002Moderate (AML/MDS)ModerateLimited

Efficacy

  • Hu5F9-G4: Achieved complete remission in 50% of NHL xenograft models when combined with rituximab .

  • AK117: Reduced tumor volume by 80% in triple-negative breast cancer models (vs. 40% for monotherapy) .

Future Directions

  • Bispecific antibodies: Combining CD47 blockade with PD-1/PD-L1 or VEGF inhibition (e.g., AK117 + AK112) .

  • Gene silencing: siRNA strategies to downregulate CD47 expression .
