LUND, Sweden, April 17, 2018 /PRNewswire/ --
Alligator Bioscience (Nasdaq Stockholm: ATORX), a biotechnology company developing antibody-based pharmaceuticals for tumor-directed immunotherapy, today presents preclinical data on the immune activating antibody ATOR-1015 at the American Association of Cancer Research (AACR) Annual Meeting 2018 taking place in Chicago, Illinois. ATOR-1015 is a first-in-class bispecific tumor-directed antibody, targeting CTLA-4 and OX40, designed to selectively activate the immune system in the tumor, without increasing systemic toxicity.
The preclinical data demonstrate that ATOR-1015 physically localizes to the tumor and selectively activates the immune system in the tumor area, confirming the intended ATOR-1015 mechanism of action.
ATOR-1015 is primarily designed for combination therapy with a PD-1 blocking antibody, and the potential of this approach is supported with preclinical data reporting enhanced anti-tumor effect of ATOR-1015 in combination with an anti-PD-1 antibody, as compared to anti-PD-1 monotherapy. In addition, ATOR-1015 demonstrated superior efficacy compared to mono-targeting CTLA-4 and OX40 antibodies.
"The results presented in Chicago confirm that our CTLA-4 bispecific antibody ATOR-1015 selectively activates the immune system in the tumor area. This offers great potential for an improved benefit/risk profile for cancer patients. We are more and more excited about the significant prospects for this unique compound, particularly in combination with PD-1 blockers, and are looking forward to initiate clinical development later in the year", said Per Norlén CEO of Alligator Bioscience.
Alligator is planning to initiate an ATOR-1015 Phase I study during the second half of 2018.
A poster with the title "CTLA-4 x OX40 bispecific antibody ATOR-1015 induces anti-tumor effects through tumor-directed immune activation" is showcased today at 8-12 a.m. EDT and is also available on the company web page www.alligatorbioscience.com.
