BioArctic Moves Forward with Exidavnemab Phase 2a Study Safety Review

BioArctic Advances Exidavnemab in Phase 2a Study Following Positive Review

BioArctic AB (publ) (NASDAQ Stockholm: BIOA B) has recently reported that the interim safety review of its clinical Phase 2a study, EXIST, concluded that exidavnemab is safe and well-tolerated. This evaluation has paved the way for the initiation of the next dose cohorts. The EXIST study aims to assess exidavnemab, which is being developed as a potential treatment for Parkinson's disease and Multiple System Atrophy (MSA).

Cohorts and Study Design

The initial cohort in the Phase 2a study examined a lower dose of exidavnemab relative to placebo, focusing on patients diagnosed with Parkinson's disease. Following a favorable safety review, the study will now proceed to evaluate two additional cohorts that will investigate a higher dose of exidavnemab in comparison with placebo, enrolling patients who have Parkinson's disease and MSA.

Insights from the CEO

Gunilla Osswald, the CEO of BioArctic, expressed enthusiasm about the results of the interim safety review, stating, "Exidavnemab is our second disease-modifying treatment targeting severe brain disorders and shares a similar scientific foundation with Leqembi®. Both therapies originate from our robust antibody platform which selects for the targeting of misfolded proteins that can be toxic. The positive safety profile observed supports the progression into higher doses for both Parkinson's disease and MSA."

Study Specifics

The EXIST study, named the EXIdavnemab Synucleinopathy Trial, is a randomized, double-blinded, placebo-controlled trial that not only evaluates the safety and tolerability of exidavnemab, but also its pharmacokinetic properties. A broad array of biomarkers are being assessed in various biological samples including plasma, cerebrospinal fluid (CSF), and through advanced digital monitors.

Understanding Exidavnemab's Mechanism

Exidavnemab targets pathological alpha-synuclein aggregates while leaving the healthy forms of this protein intact. By binding to and removing these harmful aggregates, exidavnemab aspires to halt the degeneration of nerve cells associated with diseases like Parkinson's and MSA. The need for treatments that can mitigate disease progression in these conditions is pressing.

Regulatory Recognition

Recently, exidavnemab received orphan drug designation (ODD) in the United States and a favorable opinion for orphan medicinal product designation (OD) in the European Union regarding its application in treating MSA. This recognition highlights the potential significance of the drug for those affected by rare neurological disorders.
