CEO Tara Heitner comments

Cyxone was pleased to start the quarter with a rights issue which provided the company with funding to support preparation and initiation of the Phase 2b trial of our lead asset Rabeximod in Rheumatoid Arthritis (RA).

Cyxone in a strong position to drive rheumatoid arthritis program forward with define focus and clear streamlined strategy

During the quarter Cyxone made good progress in preparations for Rabeximod in RA phase 2b trial: The instability in Europe required adjustment to our plans, and we managed to quickly make changes to ensure we have secured sites to enable the study to run smoothly.

Within this new climate, the management team and board have worked closely together to revise and agree a new forward-looking strategy. The strategy prioritizes and focuses resources on our lead asset Rabeximod and the upcoming trial in RA and will guide us through the coming year to ensure implementation of the Rabeximod trial.

Our second asset T20K has also been advanced in the first quarter with CMC activities initiated in collaboration with one of Europe’s leading peptide manufacturers. Furthermore, the academic collaboration with Medical University of Vienna has continued to deliver promising results demonstrating the enhanced therapeutic benefit of combining T20K and kappa opioid receptor agonist (KORa) therapy for the treatment of more advanced cases of multiple sclerosis. While we are prioritizing Rabeximod phase 2b trial, the ongoing activities for T20K will continue to completion and allow us to move this program forward.

Further confirmation of major market need for lead asset Rabeximod

It has become clearer than ever that Rabeximod meets a major unmet need among rheumatologists for real alternatives to current therapies. Over 40% of patients do not respond to the first line oral treatment methotrexate while 25% of diagnosed patients do not tolerate it. Second-line biologics such as TNF alpha inhibitors can provide great efficacy, but only 30% of patients respond well. Finally, the safety of oral JAK-inhibitors, a drug class that raised expectations within the specialist community when being launched about a decade ago have caused concern among both American and European authorities.  The US Food and Drug Administration (FDA) had already voiced concerns, while the European Medicines Agency’s (EMA) safety committee, PRAC, started a safety review of these drug therapies in February.

We have therefore been positioning Rabeximod with its favorable safety and tolerability profile as a second line oral therapeutic following methotrexate failure to delay the need for patients to move to more invasive and complex biologics and other injectables. Patients would be able to keep disease in remission with an effective, oral, easy to take and tolerate once a day tablet for many years. Feedback to date confirms there is a large market interest from rheumatologists, patients and strategic partners for such an approach.

Trial plans successfully adjusted

During the first quarter of 2022, we took the opportunity to optimize the trial design, increase trial efficiency and robustness, while reducing the overall cost. We are preparing for regulatory submissions in the upcoming quarter as the next important step toward patient enrolment.

T20K in Multiple Sclerosis moved to lower priority

The T20K program has delivered exceptional preclinical efficacy results in 2021-2022 and remains a key interest for the company despite a lower focus for the upcoming period. We have been testing a new subcutaneous administration form and strong synergistic effects have been shown by the T20K/KORa combination. Thus, preclinical studies have shown that T20K is effective as both an oral and subcutaneous administered drug expanding possibilities for therapy. The preclinical studies also support our new T20K/KORa combination therapy patent application and have thus expanded the potential therapeutic use of T20K to a wider MS patient population. And very importantly we have progressed the program to the non-clinical CMC phase of development with initiation of a manufacturing feasibility study for T20K. Therefore, we have further expanded our pipeline and put in place key drivers for accelerating the program when the situation allows.

Covid-19 project

Cyxone embarked upon the Covid-19 trial during the height of the pandemic in 2020 due to the extreme unmet need and our desire to make a difference. There is a potential for Rabeximod to address the cytokine storm leading to death in Covid-19 patients. After careful consideration the company has decided not to work further on Covid-19 for the following reasons:

• The focus on the RA indication which offers at least a 10-fold greater commercial opportunity.
• The market and business attractiveness are less urgent with more options available for Covid-19 patients today.

Uplisting postponed to a more advantageous time

Cyxone’s goal to uplist the company´s shares to Nasdaq main market, Stockholm remains a strategic focus, which was preliminary announced for the first quarter of this year. The uplisting is an important goal for Cyxone, however we will wait for a time when it will most benefit the company and our shareholders. We have already made extensive preparations and will be able to move swiftly when the opportunity arises.

Overall strong position

Our conviction in the need for a therapeutic like Rabeximod in the RA market for the large segment of nonresponding patients remains strong having received additional feedback from independent Key Opinion Leaders (KOL) during the quarter, which has shaped our streamlined trial design. We were also fortunate to secure additional funding early in the year to support this goal.

In conclusion, I am positive and excited for the upcoming year and the current strategy which will allow us to push our lead program forward. Implementing the optimized strategy that the company settled on, will help us deliver a successful clinical study. With a strong and focused development team, efficient organization, and additional financial resources secured in January 2022, we are well positioned to execute our drug development strategy to deliver on important upcoming clinical milestones.
