• Cyxone announced Rabeximod in Covid-19 Phase 2 trial closed
• Cyxone to leverage IND and use FDA pre-review for Covid-19 phase 2 trial

• No significant events

As Scandinavia emerged from pandemic-related lockdowns, we continued to ramp up our activities toward the initiation of a Phase 2b study of Rabeximod in a well-defined subgroup of rheumatoid arthritis patients. As we strive to reach our goal to enrol patients in the study in early 2022, the company has allocated more resources to study preparations. An important part of these activities has been the expansion of our development team. I am happy that we recently could announce the recruitment of a Chief Medical Officer as well as of two new clinical trial managers. Together they command vast knowledge in clinical development including experience in clinical rheumatoid arthritis trials. Further, having held key positions in global clinical trial management, all three bring important insights and experience into running global multisite clinical trials, giving us the best possible starting position to conduct a successful clinical study with Rabeximod in rheumatoid arthritis.

Due to recent warnings from the FDA that limit the prescription of JAK inhibitors to rheumatoid arthritis patients, the need for new safe and effective long-term disease-modifying therapies has become more acute. Since Rabeximod has been proven safe and well-tolerated in a previous clinical Phase 2a study, we see an increased market void for our lead drug candidate, which we hope to be a potential treatment option with high impact.

While the world is slowly but steadily coming to enjoy the benefits of the newly developed vaccines toward Covid-19, the need for effective therapies limiting the severe effects from an infection remain a defined need in many parts of the world, including Europe and the U.S. Cyxone recently concluded a clinical Phase 2 study of Rabeximod in Covid-19 patients. The study included around 90 patients who were enrolled into three treatment arms; two where the patients received either a low dose or a high dose of Rabeximod, and one placebo arm.

Provided positive results from the recently concluded Phase 2 study, we will engage with the relevant regulatory authorities in order to outline the most effective pathway toward a potential market approval. In order to fund the continued development for Rabeximod in Covid-19, Cyxone intends to seek a commercial partnership, or external funding via development grants.

In July, a collaboration with the Medical University of Vienna was initiated. The aim of the partnership is to explore the drug candidate’s mode of action, as well as to expand the potential medical use of T20K in multiple sclerosis. T20K has previously shown positive properties in preclinical studies, pointing toward decreased levels of inflammatory cytokines and ameliorating effects on disease onset and severity. Based on these important insights we are now honing in on a more optimal drug formulation and administrative route for T20K – a challenging feat where drug efficacy, patient convenience, and manufacturing optimization, among other parameters, are balanced. The results from these formulation studies will serve as foundation for the next step ahead, which include non-clinical and clinical studies.

All in all, we are facing an eventful time period in the near future, with each step taking us closer to reaching our goal of providing millions of patients suffering from debilitating diseases with better therapies.
