In two separate phase 1 clinical studies conducted in collaboration with AbbVie, exidavnemab was tested on healthy volunteers to assess the safety, tolerability and pharmacokinetics of the candidate drug. The studies included 98 participants from different ethnic backgrounds, of which 85 received exidavnemab, either as an intravenous dose ranging from 100 to 6000 mg or a subcutaneous dose of 300 mg.

The results showed that exidavnemab was generally well-tolerated. with an excellent half-life of approximately 30 days. This together with the high affinity and selectivity toward the pathological aggregated forms of α-synuclein is key to maintain a high target binding in the brain.

"Data from these two studies support the continued clinical development of exidavnemab, and we are looking forward to starting the phase 2a study later this year," said Gunilla Osswald, CEO of BioArctic, in a comment.

About Exidavnemab
Exidavnemab is a monoclonal antibody drug candidate that is designed to selectively bind and eliminate aggregated forms of alpha-synuclein such as oligomers and protofibrils and fibrillar forms, which participates in neurodegenerative disorders including Parkinson's disease. The goal is to develop a disease modifying treatment that stops or slow down the progression of Parkinson's disease.
