Orexo's partner Gesynta Pharma granted Orphan Drug Designation by the FDA for OX-MPI (GS-248) for the treatment of systemic sclerosis

UPPSALA, Sweden, April 27, 2022 /PRNewswire/ -- Orexo AB (publ.), (STO:ORX) (OTCQX:ORXOY), announces today that the company´s partner Gesynta Pharma AB which owns all the rights to OX-MPI (GS248), a drug candidate for the treatment of systemic sclerosis, has been granted Orphan Drug Designation in the US by the Food and Drug Administration (FDA).

Systemic sclerosis (also known as scleroderma) is a chronic, autoimmune disease that affects, among other things, the body's smallest vessels, the microvasculature, and is associated with great medical needs due to the current lack of safe and effective medicines. OX-MPI (GS-248) has a unique and promising mechanism of action with the potential to help both patients with systemic sclerosis and patients with other chronic inflammatory diseases. The drug candidate is currently being evaluated in a clinical phase 2 trial and data is expected in late 2022.

Orphan Drug Designation is intended to encourage the development of drugs for the treatment of rare diseases. This exclusive classification provides up to seven years of market exclusivity and also gives some financial benefits during the development phase.

Nikolaj Sørensen, CEO & President of Orexo, commented: "We are very pleased with the progress Gesynta Pharma has made with our former OX-MPI (GS-248) project. Obtaining orphan drug status in the US, is a true milestone to ensure the pharmaceutical reaches the patients suffering from systemic sclerosis as soon as possible. We are looking forward to see the result of the ongoing phase 2 trial later this year. With a successful outcome we are confident Gesynta Pharma, with their experienced and competent management team, are well positioned to develop OX-MPI (GS-248) to a commercial success."

"The orphan drug designation granted to our drug candidate GS-248 for the treatment of systemic sclerosis provides an opportunity for extended market exclusivity, which is a valuable complement to its strong patent protection. Strengthened by this positive news and our constructive dialogue with the FDA, we continue working towards the goal of being able to offer an effective and safe treatment for patients with systemic sclerosis," says Patric Stenberg, CEO of Gesynta Pharma.

According to the agreement, signed in 2017, Orexo will receive a tiered double digit share of future revenues that Gesynta Pharma generates from the OX-MPI (GS248) project.
