PRESS RELEASE

October 26, 2017

Saniona, a leading biotech company in the field of ion channels, today announces that nine out of a planned ten adult patients with Prader-Willi syndrome have completed or discontinued from the Phase 2 clinical study. Some patients showed indication of weight loss and reduced craving for food, the key efficacy endpoints. Some patients discontinued the study due to adverse effects, which might be drug related. This interim analysis will last about 2-3 months and based on the results Saniona will decide on the next steps for Tesomet in Prader-Willi syndrome.

"Prader-Willy syndrome is a complex disease with a high occurrence of concomitant co-morbidities. Many patients have major behavioural and psychiatric abnormalities at the time they reach adulthood and communication represents a challenge when performing clinical studies. Based on our observations, we see a need to un-blind the study and analyse data on individual patient's drug exposure in relation to observed efficacy and safety signals before we decide on next steps", says Jørgen Drejer, CEO of Saniona.

The actual assignment of patients to respective treatment arms is currently unknown since the placebo controlled study is still blinded. The indications of a reduction in weight and craving for food are encouraging whereas the discontinuation of five patients due adverse effects, potentially drug related, may indicate that we have used a too high dose in this study.

"We highly appreciate the dedicated and professional efforts from the primary investigators Dr. Torok in Hungary and Dr. Kolouskova in the Czech Republic and their staff to find and manage these demanding patients", says Jørgen Drejer, CEO of Saniona.
