Lund, Sweden, November 12, 2021 – Alligator Bioscience AB (“Alligator” or the “Company”) today announced that the design and scientific rationale of OPTIMIZE-1, Alligator´s phase 2 study (NCT02829099) in 1st line metastatic pancreatic cancer in combination with mFOLFIRINOX, will be presented at the Society for Immunotherapy Cancer’s (SITC) 36th Annual Meeting & Pre-Conference Programs virtually on November 10th – 14th, 2021.

"Mitazalimab, a best-in-class second generation CD40 agonist, reported positive clinical data from Phase I studies, displaying a manageable safety profile, proof-of-mechanism as well as early signs of efficacy. OPTIMIZE-1 reinforces our commitment to developing mitazalimab in combination with standard of care therapies," stated Yago Pico de Coaña, PhD., Medical Science Director at Alligator Bioscience. “Targeting CD40 with mitazalimab in pancreatic ductal adenocarcinoma (PDAC), has the potential to augment responses to chemotherapy, initiating an effective anti-tumor immune response and potentially better tumor control.”
