KARO BIO RECEIVES FUNDING FROM THE NATIONAL MS SOCIETY TO DEVELOP ERBETA AGONISTS FOR TREATMENT OF PROGRESSIVE MULTIPLE SCLEROSIS

STOCKHOLM, 12 September 2013 - Karo Bio AB has been awarded $0,5 million from
the National Multiple Sclerosis Society through Fast Forward to develop a novel
treatment – ERbeta agonists -- for progressive forms of Multiple Sclerosis (MS).
The funds will finance the further preclinical development of Karo Bio’s
advanced compounds.
Karo Bio’s ERbeta agonist has the potential to slow disease progression in
multiple sclerosis as preclinical models show that it protects neurons and
restores myelin. Damaged myelin leads to symptoms of illness and disability in
MS patients. This intended profile differs dramatically from currently approved
MS therapies, which are used for the treatment of relapsing MS and reduce
inflammation, but do not restore myelin or directly protect neurons.

“We are very pleased to have received this funding from the National MS Society
to support our efforts to address important unmet medical needs among MS
patients” says Per Bengtsson, CEO of Karo Bio. “Our aim is to achieve a
significant breakthrough in the treatment of MS.”

This investment by the National MS Society is a continuation of a strategic
research focus on gender differences in MS. That effort helped drive basic
research into the role of sex hormones, and estrogen in particular. Karo Bio’s
development of ERbeta agonists reflects the potential of this approach, and fits
the Society’s comprehensive strategy to stop the progression of disability in MS
and to restore function.
