Significant events during the third quarter 2022

On July 26, Isofol received approval of a biomarker analysis patent.
On August 3, Isofol presented the top-line results of the global pivotal phase III AGENT study. The study data revealed that the study did not achieve the primary endpoint of objective response rate (ORR) or the key secondary endpoint of progression-free survival (PFS).
On August 31, Isofol announced that based on additional study data, there was no longer reason to continue with the AGENT study. The conclusions regarding primary and secondary endpoints will not be revised. Isofol's Board resolved to assess possible alternatives for the company's future.
On September 7, Isofol reported additional study data that laid the groundwork for the decision to terminate the study early. In parallel with this decision, Isofol's Board will continue to investigate possible alternatives to secure the largest possible value for Isofol's shareholders.

Significant events after the event of the period

• No significant events occurred after the end of the period.

CEO´s comment:

" Given the AGENT study results' low clinical and business value for Isofol, we began work during the quarter to terminate the study. This must be carried out in accordance with applicable ethical aspects and regulatory requirements. This work is extensive and will therefore require both time and resources throughout autumn 2022 and the beginning of 2023. We also took active measures to reduce costs and secure the company's financial position, which has been our utmost priority

along with finding any positive outcomes in the study data and terminating the study", says CEO Ulf Jungnelius.
