STOCKHOLM, Nov. 6, 2024
/PRNewswire/ -- BioArctic AB (publ) (NASDAQ: BIOA B) (STOCKHOLM: BIOA B) has presented the design of
its proprietary BrainTransporter (BT) platform at the
16th annual Protein & Antibody Engineering
Summit (PEGS) conference in Barcelona,
Spain. The BT platform uses active Transferrin Receptor
(TfR)-mediated transport, enabling up to 70-fold higher penetration
of antibodies over the blood brain barrier, without negative
effects on hematological safety parameters.
During the 16th annual Protein & Antibody
Engineering Summit (PEGS) Europe
conference, Dr. Per-Ola Freskgård, VP Science & Technology at
BioArctic, presented for the first time the design of the
proprietary BT platform as well as validation in preclinical
models.
Brain uptake of biotherapeutics such as antibodies and
enzymes is severely limited by the blood brain barrier (BBB)
primarily due to their size. Active transport across the BBB, using
one of the body's own delivery mechanisms, aims to enable better
drug uptake into the brain. The BT technology utilizes the
Transferrin Receptor (TfR), a protein facilitating transport
across the BBB, to optimize brain delivery.
The PEGS summit presentation included results in
preclinical models demonstrating up to 70-fold increase of
amyloid-beta antibody brain exposure using the BT technology, with
a rapid, broad and deep distribution of amyloid-beta antibodies
across the brain. The results provide preclinical validation of a
BT-linked amyloid-beta monoclonal antibody, without negative
effects on hematological parameters including reticulocytes.
"I am excited that we now can present our excellent preclinical
data with the BrainTransporter technology. This technology has huge
potential to improve many therapies by helping more drug reach its
target in the brain, and could thereby in the future offer patients
with different brain disorders new treatment opportunities," said
Gunilla Osswald, CEO at BioArctic.
"The technology has the potential to create faster and improved
efficacy of treatments targeted to the brain with less side effects
and lower doses for the benefit of both patients and society."
The BT technology could be used in a number of different
therapy areas, giving BioArctic many potential future partnering
opportunities. A first agreement with the BT-technology was signed
in April 2024, when BioArctic AB and
Eisai Co., Ltd., entered into a research evaluation agreement
regarding BAN2802, a potential new treatment combining BioArctic's
proprietary BrainTransporter technology with an undisclosed
Alzheimer drug candidate.
This release discusses investigational uses of an agent in
development and is not intended to convey conclusions about
efficacy or safety. There is no guarantee that such investigational
agents will successfully complete clinical development or gain
health authority approval.
The information was released for public disclosure, through
the agency of the contact person above, at 3.00 p.m. CET on November
6, 2024.

About the BrainTransporter technology
BioArctic's BrainTransporter technology is a technology for
facilitating the passage of biological drugs as for example
antibodies into the brain using the transferrin receptor (TfR).
Active transport of biotherapeutics across the blood brain barrier
can result in broader brain distribution enabling better efficacy,
improved safety profile and dosing convenience. The technology is
being applied to several in-house drug projects and could become
part of future collaborations with other pharma companies.
About BioArctic
BioArctic AB (publ) is a Swedish research-based biopharma company
focusing on treatments that can delay or stop the progression of
neurodegenerative diseases. The company invented Leqembi®
(lecanemab) - the world's first drug proven to slow the progression
of the disease and reduce cognitive impairment in early Alzheimer's
disease. Leqembi has been developed together with BioArctic's
partner Eisai, who are responsible for regulatory interactions and
commercialization globally. In addition to Leqembi, BioArctic has a
broad research portfolio with antibodies against Parkinson's
disease and ALS as well as additional projects against Alzheimer's
disease. Several of the projects utilize the company's proprietary
BrainTransporter™ technology, which has the potential to actively
transport antibodies across the blood-brain barrier to enhance the
efficacy of the treatment. BioArctic's B share (BIOA B) is listed
on Nasdaq Stockholm Large Cap. For further information, please
