CEO Kjell Stenberg comments

"Several important advances have recently been made for both T20K and rabeximod, laying a solid foundation for future studies and activities. I am enthusiastic and optimistic as I return to the Company and look forward to the future with great confidence. I will prioritize and continue the development of rabeximod and its new formulation. In parallel, we will also develop a clear plan to optimize the value of our exciting T20K project.

To continue our development, we intend to raise capital to advance our efforts with both T20K and rabeximod in preclinical and clinical studies and to find strategic partners. Strategic collaborations in these clinical stages - especially in indications such as rheumatoid arthritis, where further clinical development would involve significant costs for a small company like Cyxone - are common. We are confident that with a well-executed preclinical and early clinical study data package for rabeximod, we will be in an excellent position to reach strategic agreements and create increased value for the compound."

Background and motive

Despite advances in the treatment of rheumatoid arthritis ("RA") and multiple sclerosis ("MS"), there is still a need for safer and more effective treatments for both indications.

Cyxone's product portfolio currently consists of two candidates - rabeximod and T20K. Rabeximod, a drug candidate for the treatment of moderately to severely active RA, has a favorable safety profile and is in clinical phase II. T20K is in preclinical development, ready for clinical development, for MS. Both candidates have mechanisms for growth in other indications; rabeximod can treat other autoimmune diseases and T20K can treat central nervous system ("CNS") diseases.

The Company's goal is to offer new, effective, safe and easy-to-use medicines for autoimmune inflammatory conditions to improve patients' quality of life. Cyxone also aims to collaborate with established pharmaceutical companies in clinical phases to finance, develop and launch rabeximod globally.

For the next 12 months, the Company is in need of additional working capital. In order to continue development with rabeximod and T20K, the board has decided to carry out the Rights Issue. The primary purpose of the Rights Issue is to finance development programs with exploratory studies with the drug candidate rabeximod for patients who do not respond well to TNFa inhibitors, as well as to finance development of T20K and the overall operational activities.

Provided that the Rights Issue is fully subscribed, the Company has the resources to finance the operations and development plans for the Q3 2025. If the Company through the Rights Issue does not obtain the necessary capital to finance the operations for a period of at least 12 months ahead, the Company intends to evaluate alternative financing solutions.

Objectives

• Initiation of collaboration with world-leading clinical experts for the treatment of RA in patients unresponsive to anti-TNK alpha therapy.
• Preclinical studies to explore details of rabeximod's mechanism of action to guide prioritization of future clinical studies.
• Preclinical studies to investigate T20K's ability to halt the progression of MS symptoms in early, middle and late stages of development.
• Explore combinations of T20K and a kappa opioid receptor agonist ("KOR agonist") to optimize efficacy versus safety in the EAE model.
• Preclinical studies to explore the potential use of rabeximod in other diseases where the pathophysiological processes are likely to be inhibited by rabeximod.
• Initiate partnership discussions in mid-late 2025 for rabeximod and/or T20K, depending on the results of the preclinical studies.
• Obtain advice from regulatory authorities and conduct a pre-IND program with a combination of T20K and a KOR agonist results from preclinical studies of T20K. Investigate the potential of T20K alone or in combination with KOR agonist in disease.
• Identify pharmaceutical partners that can fund clinical trials for T20K and/or rabeximod.
