LUND, Sweden I April 18, 2023 I
Alligator Bioscience (Nasdaq Stockholm: ATORX) today announces the company presented a poster on ATOR-4066, a Neo-X-Prime™ bispecific antibody (bsAb), at the American Association for Cancer Research (AACR) Annual Meeting, taking place April 14-19, 2023, in Orlando, Florida.
The presentation, entitled
"ATOR-4066, a Neo-X-Prime™ bispecific antibody targeting CD40 and CEA, activates myeloid cells in primary human tumors in vitro and induces anti-tumor immunity in vivo"
, highlights how ATOR-4066 has the potential to induce strong anti-tumor responses in patients with carcinoembryonic antigen 5 (CEACAM5)-expressing tumors.
CEACAM5, a well described clinical target for cancer therapy, is a glycoprotein that is overexpressed on the cell surface of many cancers including colorectal, gastric, pancreatic, and non-small cell lung cancer, with limited expression in normal adult tissue. Thus, it is an ideal target for a tumor-directed bispecific conditional CD40 agonist like ATOR-4066.
The data demonstrate CEACAM5 expression in relevant indications and how ATOR-4066 induces:
"We are excited to be presenting new data from our novel Neo-X-Prime approach at this year's AACR meeting,"
said
Søren Bregenholt, CEO of Alligator Bioscience.
"We have already shown that simultaneously targeting CD40 and tumor associated antigens leads to superior anti-tumor immunity. These new data further demonstrate the ability of ATOR-4066 to remodel the immune microenvironment and, as it continues to show great potential in inducing strong anti-tumor responses in CEACAM5-expressing tumors, we remain committed to advancing ATOR-4066 towards the clinic."
