The unblinded data from the study shows that Apta-1 has been well tolerated in the given doses. No serious side effects were seen and all participants fulfilled the study. In the additional analyzes that were performed during the study Apta-1 showed signs of having effect on some markers which are important for understanding its mechanism of action. The significance of these findings will be evaluated in the continued preclinical and future clinical studies.

CEO Mikael Lindstam comments:

"I am pleased to say that the preliminary unblinded results confirm what we previously have communicated. While we wait for the final study report we continue to plan for the next step in the clinical development program for Apta-1 based on these insights."
