“We’re very pleased to have this peer-reviewed article prepared by Alligator’s scientists published. It highlights the promising role of CD40 agonists in immuno-oncology and explains how Alligator’s CD40 agonist, mitazalimab, has best in class potential,” said Søren Bregenholt, CEO of Alligator Bioscience. “We’re now looking forward to initiating the OPTIMIZE-1 Phase II study designed to assess the clinical efficacy of mitazalimab combined with chemotherapy in patients with metastatic pancreatic cancer.”

Mitazalimab is an agonistic – or stimulatory – antibody that targets CD40, a receptor on dendritic cells, which are the cells that instruct T cells to kill cancer cells. Mitazalimab activates CD40 enabling dendritic cells to effectively stimulate the immune system directing T cells to selectively attack the tumor. This addresses one of the key mechanistic needs in immuno-oncology and highlights the potential of CD40 as a target to treat patients with metastatic cancer. Mitazalimab’s favorable efficacy-safety profile demonstrated in previous phase I studies, makes it ideal for combination with standard of care treatments such a chemotherapy, check-point inhibitors or cancer vaccines.
