Idogen has previously received approval from both the Swedish and the Norwegian Medicines Agency to start the study, and in Norway, patients who are suitable for inclusion have now been identified. Professor Pål Andre Holme, senior physician at Oslo University Hospital and clinical investigator in Idogen's study, says in an interview with BioStock that he expects to soon       be able to start the study and hopes to start after the summer. What remains in Norway is an approval from the local ethics committee.

"Idogen's cell therapy is a completely new type of treatment that we hope will enable many hemophilia A patients to once again benefit from FVIII treatment, which would have very positive consequences. I look forward to seeing the results of the phase 1/2a study," he says and continues:

"In Norway, we will primarily initiate the treatment on one patient, which is expected to be carried out shortly, hopefully shortly after the summer".

"The strong interest we are seeing for our phase 1/2a study with IDO 8 is incredibly motivating for me and the entire Idogen development team. We have succeeded in recruiting leading centers - both in the Nordics and in other parts of Europe. With these centers on board, we gather broad expertise in the treatment of severe hemophilia A with antibodies against FVIII. It is very gratifying to meet their commitment to our study with IDO 8 and their hopes for this new and unique treatment method", says Anders Karlsson, CEO of Idogen.

The approvals the company received to start the study in Sweden and Norway are now being used to obtain a combined approval that includes all countries in the EU. For the UK, the approval process is based on the work done previously in Sweden and Norway.

Idogen (Nasdaq First Growth Market: IDOGEN) develops tolerogenic cell therapies to prevent the patient's immune system from attacking biological agents, transplanted organs or the body's own cells or tissue. The company's most advanced project, IDO 8, is designed to restore the efficacy of hemophilia drugs in patients who have developed neutralizing antibodies. The company's second project, IDO T, is being developed to prevent kidney transplant rejection. In a third programme, IDO AID, Idogen is focused on the treatment of autoimmune diseases. The treatment for all indications is based on the patient's own

cells and is expected to have a favorable safety profile and long-lasting effect. The potential for a short-term treatment intervention to yield a long-term effect is a major advantage in health economics for both patients and divisions providing care.
