The Japanese Patent Office (JPO) has granted a new drug substance patent for Swedish biopharma company BioArctic’s monoclonal antibody (mAb), BAN0805, to treat Parkinson’s disease.
The patent for the antibody will expire in 2041, with the potential for extension until 2046.
BAN0805 selectively attaches to and removes oligomers, which are pathological aggregated forms, as well as protofibrils. It does not impact the alpha-synuclein’s physiological monomer form.
The company plans to advance the mAb as a treatment that stops or decelerates Parkinson’s disease progression.
Findings from a Phase I clinical trial of BAN0805 supported the continued development of BAN0805 in a Phase II study, dosing once a month.
BioArctic CEO Gunilla Osswald stated: “I am delighted to announce that the Japanese Patent Office is granting a new drug substance patent for BAN0805, securing a valuable and extensive period of patent protection.
