After analyzing the results from the performed Phase 1a study, including the additional studies, and having discussions with leading Key Opinion Leaders within relevant areas, the company has taken the decision to change the strategy for the clinical development program for Apta-1. The next step will be to perform a Phase 2 study in patients unlike the previously communicated plan which was to perform a study in healthy volunteers (a Phase 1b study).

CEO Mikael Lindstam comments:

"We have, after careful consideration, decided that the best and fastest way forward in the development of our lead candidate Apta-1 is to perform a Phase 2 PoC study in patients. The decision is based on all the results we have seen in the phase 1a study together with the discussions we have had with a number of experts. I am convinced that this is the best way forward considering Apta-1's potential and to strengthen the potential to attract collaboration partners."
