Alligator Announces Poster Presentation on ATOR-1017 at SITC Virtual Annual Meeting 2021
Poster presentation to highlight the ability of ATOR-1017 to activate and rescue tumor infiltrating exhausted T cells in synergy with PD-1
Lund, Sweden, November 12, 2021 – Alligator Bioscience AB (“Alligator” or the “Company”) today announced new preclinical data highlighting the 4-1BB (CD137) antibody ATOR-1017 including an update on the ongoing phase 1 study. ATOR-1017, a promising candidate for immunotherapy with enormous potential for combination with other immunomodulatory antibodies, will be presented at the Society for Immunotherapy Cancer’s (SITC) 36th Annual Meeting & Pre-Conference Programs virtually on November 10th – 14th, 2021.
"By combining ATOR-1017 with antibodies blocking PD-1, tumor infiltrating T cells, in particular exhausted tumor specific T cells, can be more effectively activated and potentially increase the response rate in multiple types of cancer," stated Karin Enell Smith, PhD, MS, Principal Scientist at Alligator Bioscience. “The functional activation profile of ATOR-1017 is expected to minimize the risk of systemic immune activation and toxicity, by directing a potent immune response to immune cells in tumor tissue and tumor draining lymph nodes. This is supported by early data from the ongoing first-in human phase I study where ATOR-1017 has been shown to be safe and tolerable. These results support further clinical development of ATOR-1017 in combination with PD-1 blocking antibodies”
In addition, the poster includes data from the 360 mg cohort of the ongoing ATOR-1017 phase 1 study.
