Alligator Bioscience presents the CD40 antibody mitazalimab at the World Immunotherapy Congress 2020

- Strong benchmark to competitor CD40 antibodies

LUND, Sweden, Nov. 5, 2020 /PRNewswire/ -- Alligator Bioscience (Nasdaq Stockholm: ATORX) today announced that its CD40 targeting antibody mitazalimab will be presented at the World Immunotherapy Congress, November 2-6, 2020. The presentation will include new benchmark data demonstrating that mitazalimab has the potential to be best-in-class in the CD40 field.

The new preclinical data include analyses of mitazalimab compared with analogues of the CD40 antibodies of key competitors. The comparison demonstrates the potent immune-activating properties and anti-tumor effects of mitazalimab.

Mitazalimab's mode of action is clearly dependent on Fc-gamma-receptor engagement, resulting in a more tumor-selective immune-activation. This differentiation may translate into a superior risk-benefit profile in patients.

The presentation will also summarize previously released clinical data from the Phase I study performed by Janssen Biotech Inc. Mitazalimab shows a manageable safety profile both with and without corticosteroid premedication. A partial response was observed in one patient with renal cell cancer and 10 patients with different advanced cancers showed stable disease lasting ≥ 6 months. In addition, clinical biomarker data confirm proof of mechanism in patients.

"The solid clinical package from Phase I and the new favorable benchmark data to our key competitors further strengthen our belief in mitazalimab as a potent immunotherapy agent. Mitazalimab has demonstrated strong activity and superior tolerability, which probably reflects the fact that the antibody has been optimized for more tumor-selective effects", said Per Norlén, CEO at Alligator Bioscience. "We are now completing the clinical file for the submission of the CTA for the upcoming Phase Ib/II efficacy study in pancreatic cancer," he added.

Dr Peter Ellmark, VP Discovery, Alligator Bioscience will give an oral presentation with the title "Mitazalimab - a CD40 agonist to unleash CD40 in immuno-oncology" on November 5, 2020, at 12:50 p.m CET.
