InterAx Biotech, MS Center Amsterdam and the Vrije Universiteit Amsterdam join forces to unlock a novel target to promote remyelination in Multiple Sclerosis

Villigen – Switzerland, Amsterdam – The Netherlands, July 15th 2022

InterAx Biotech, the MS center of Amsterdam UMC and the Vrije Universiteit Amsterdam announce that they will combine complementary technologies to design and validate the efficacy of bioactive molecules to promote neuroprotection and remyelination. The efforts will open novel avenues to treat progressive multiple sclerosis.

Multiple sclerosis (MS) is one of the most common diseases of the central nervous system (brain and spinal cord). Today, more than 2.8 million people around the world suffer from MS. In Europe, the incidence it about 1 in every 450 people, of which more than 70% are women [1]. The chronic disease disrupts the ability of the nerves to conduct electrical impulses to and from the brain causing various symptoms including fatigue and cognitive and movement problems, resulting in progressive lifelong disabilities.
The goal of the program is to design and validate the efficacy of new compounds to promote remyelination and neuronal function in patients with MS to slow down disease progression. This will be a breakthrough compared to the current standard of care based on reduction of disease activity and management of symptoms.

In the collaboration, partners will optimize hit molecules steered by the InterAx’s artificial intelligence driven discovery platform. Optimization and synthesis approaches, as well as pharmacology and toxicology efforts will be led by Rob Leurs (Medicinal Chemistry) at the Vrije Universiteit Amsterdam. At the MS Center Amsterdam, selected molecules will first be tested by Elga de Vries and Merel Rijnsburger (Molecular Cell Biology and Immunology, UMC) for their effect on remyelination in experimental models. Compounds that show promising effects based on multi-parameter optimization will be chosen for further in vivo studies. An innovative cortical animal model of MS that reflects both neurodegeneration and demyelination, as seen in MS patients, will be used to test the most promising compounds.

With this project, InterAx Biotech, MS Center Amsterdam and the Vrije Universiteit Amsterdam are further strengthening their successful long-term relationship. The partnership already led to the discovery of first in class drug molecules with high affinity and potency on a novel target that are under further investigation as anti-cancer therapy in animals. Initial promising results in vitro show that the drug molecules block proliferation and migration of breast cancer cells, and also blocks in vivo the receptor target function – thus promising to stop tumor growth and metastasis.

The project is supported by Consortium Knowledge and Innovation (TKI) for high quality and highly promising industry-academia collaborations, a program from Health Holland – Top Sector Life Sciences & Health.
