LUND, Sweden, Oct. 30, 2018 /PRNewswire/ --
Alligator Bioscience AB (Nasdaq Stockholm: ATORX), a biotechnology company developing antibody-based pharmaceuticals for tumor-directed immunotherapy, today announces that a new bispecific drug candidate, ATOR-1144, has entered preclinical development. ATOR-1144 is a first-in-class bispecific tumor-localized antibody targeting the checkpoint inhibitor CTLA-4 and the co-stimulatory receptor GITR.
The bispecific antibody ATOR-1144 is a dual immune activator targeting CTLA-4 and GITR. It works through several pathways, including activation of T cells, depletion of regulatory T cells (Tregs) and activation of NK (natural killer) cells, for enhanced tumor cell killing. Based on its mode of action, ATOR-1144 may be suitable for the treatment of solid tumors as well as hematological cancers.
"We are very excited about the new drug candidate ATOR-1144, which is a novel tumor-localizing CTLA-4 bispecific antibody with the potential for enhanced Treg depletion. This latest progress further demonstrates Alligator's capabilities in generating innovative bispecific immunotherapies", said Per Norlén, CEO of Alligator Bioscience.
