LANI completes Phase I in Japan and to commence Phase I in UK
Melbourne, Australia — 19 April 2007- Biota Holdings
Limited (ASX:BTA) today announced that its long acting
neuraminidase inhibitor (LANI), CS8958, an anti-influenza
treatment, has:
1. demonstrated effectiveness against the avian flu virus
H5N1;
2. completed Phase I studies in Japan; and
3. received ethics approval to commence comparable studies in the
UK.
Biota’s partner for LANI, Daiichi-Sankyo, overnight announced
that laboratory
studies had confirmed CS8958’s effectiveness against the
avian flu virus H5N1 in
addition to its effectiveness against influenza A and B type
non-avian viruses.
Daiichi-Sankyo also announced that it has completed a Phase I
clinical trial in Japan
on CS8958 and expects to start Phase II studies in October.
The UK studies will extend the safety and pharmacokinetics studies
of CS8958 in
man. The double-blinded study will involve up to 40 healthy
volunteers using a
single dose, and will trial up to four separate, single dose
levels. The study is being
funded as part of a US$5.6 million grant provided by the US
National Institutes of
Health. The studies will utilise a newly licensed inhaler designed
by Hovione and
complement the studies completed by Daiichi-Sankyo in Japan. The UK
studies will
generate data in western subjects and lay the basis for further
clinical development
outside Japan.
CS8958 is a long acting neuraminidase inhibitor and offers higher
potency, lower
dose and the potential for once only treatment and once weekly
prophylactic
protection from influenza. These properties are known consumer
advantages over
existing inhaled and oral therapies.
CS8958 and a range of other LANI type compounds are co-owned by
Biota and
Daiichi-Sankyo.
Biota CEO, Peter Cook said “These are important milestones in
the development of
second generation anti-influenza products. We have every confidence
in the
product’s profile as it offers the potential for a very real
improvement in therapy for
both the prescriber and ultimate user of the product”.

Completion of Phase I Trial on the Anti-influenza Drug
CS-8958
Tokyo, April 18, 2007 – DAIICHI SANKYO COMPANY, LIMITED
announced today that it
has completed a Phase I clinical trial in Japan on the DAIICHI
SANKYO-originated antiinfluenza
drug CS-8958 and expects to start Phase II trials this fall.
CS-8958 is a long-acting neuraminidase inhibitor that is expected
to show a therapeutic effect
only by one administration and a protective effect by one
administration a week. The
compound is under development as an inhalant that will act directly
on the pulmonary and
tracheal sites of infection. Non-clinical studies have confirmed
its effectiveness against the
H5N1 avian flu virus in addition to its effectiveness against both
A and B type non-avian flu
viruses.
CS-8958 was designated as a priority item for face-to-face
consultation and advice by the
Pharmaceuticals and Medical Devices Agency (PMDA) in August 2006,
which will give it
priority for consultations on clinical trial planning and other
issues. DAIICHI SANKYO aims
to file an NDA at end-2009 and is pursuing development in full
consultation with the
regulatory authorities and specialists. As measures are stepped up
to deal with new strains of
influenza virus, CS-8958 may make an important contribution by
increasing the range of
options available for treating and preventing flu infections.
In Europe and the US, Australia-based Biota Holdings Ltd., a joint
development company, is
conducting Phase I trials for CS-8958.
