Lund, Sweden – Alligator Bioscience (Nasdaq Stockholm: ATORX)

"During another busy and productive quarter for Alligator we achieved one more important milestone in the clinical and commercial development of our lead asset with the addition of orphan designation for mitazalimab in pancreatic cancer by the European regulator. This follows our receipt of orphan drug designation in the US from the FDA and means we have now secured greater commercial protection for mitazalimab upon approval in our two key markets, the US and the EU. Over the summer, we showcased mitazalimab's scientific achievements at several prestigious industry conferences, through which we continue to raise mitazalimab's profile among the world's top oncologists, investors and potential partners. On the partnership front, we reported the achievement of Technical Feasibility in one of our collaboration programs with Orion, which triggered a milestone payment to us. Our work with Orion is a great example of the benefits these strategic collaborations can deliver for our company and our shareholders. We have much to look forward to in the coming months, in particular the next major inflection point in our OPTIMIZE-1 study, which is due to report its top-line Phase 2 data at the start of next year and which will mark the start of the next stage of mitazalimab's route to market."

Søren Bregenholt, CEO of Alligator Bioscience
