Teitur develops novel therapeutics for treating or preventing neurodegenerative diseases. The company’s ambition and commitment is to create new treatments for patients suffering from neurodegenerative diseases to help them live a longer, better and happier life.

From the Sortilins family of receptors, Teitur has developed cyclic peptides with a unique potential for addressing key pathologies across several neurodegenerative disorders.

More than 200 million patients suffer from neurodegenerative disorders world-wide. Today, no treatments are available to prevent the relentless progression of neurodegeneration, affecting memory, movement, and quality of life for them and their loved ones.

Teitur is dedicated to developing novel compounds that can address this unmet medical need and provide true disease modifying opportunities to improve the lives of patients. P53 Invest participated in a series A round lead by Sunstone Life Science Ventures and Sound Bioventures, together with Industrifonden and Innovestor’s Life Science Fund

Arxx Therapeutics develops a first-in-class monoclonal antibody with a unique mechanism of action targeting non-resolving tissue fibrosis.

The company leverages more than 30 years of research by its scientific co-founders uncovering the pathobiology of S100A4; a Damage Associated Molecular Pattern protein upregulated upon stress or injury allowing cells to sense and react to danger. In chronically diseased tissue, S100A4 is inappropriately activated which leads to persistent inflammation and non-resolving tissue fibrosis.

Arxx’s lead candidate AX-202 is a high-affinity monoclonal antibody neutralizing the bioactivity of S100A4. AX-202 confers targeted, upstream and disease-specific modulation of the self-sustaining feedback loop driving persistent fibrogenesis.
