Basilea's novel oncology drug candidate BAL101553: data

Basilea's novel oncology drug candidate BAL101553: data presented at
international conference demonstrate dual mode of action 
BASEL, SWITZERLAND -- (Marketwire) -- 11/06/12 --  Basilea
Pharmaceutica AG / Basilea's novel oncology drug candidate BAL101553:
data presented at international conference demonstrate dual mode of
action. Processed and transmitted by Thomson Reuters ONE. The issuer

Basilea Pharmaceutica Ltd. (SIX: BSLN) reported today that new
research data on its innovative anti-cancer drug BAL101553 are being
presented at the 24(th) Symposium on "Molecular Targets and
Cancer
Therapeutics" taking place in Dublin, Ireland, from November 6 to 9,
2012, hosted by the European Organisation for Research and Treatment
of Cancer (EORTC), the U.S. National Cancer Institute (NCI) and the
American Association for Cancer Research (AACR). 
BAL101553, a highly soluble prodrug of Basilea's BAL27862, is a novel
small molecule agent targeting microtubules, the intracellular
structural network essential for cell division. BAL27862 has
demonstrated broad anti-cancer activity in preclinical models of
human cancer resistant to conventional microtubule-targeting drugs
such as taxanes or vinca alkaloids. BAL101553 has
potential for both
intravenous and oral administration. The injectable form is
currently
being tested in a phase I study in patients with advanced solid
tumors. 
BAL101553 has a dual mechanism of action (poster/abstract #421) with
direct activity against drug-resistant cancer cells and a pronounced
effect on eliminating tumor blood supply. In animal models,
short-term treatment of tumors
led to a dramatic reduction in tumor
cell growth and viability, associated with
almost complete
eradication of functional tumor blood vessels. Importantly, blood
vessel function in normal tissue was not affected. Vascular
disruption
activity was also shown in an in vitro model that mimics
capillary formation. 
Further data supporting the unique anti-cancer profile and mode of
action of
this novel agent were generated in collaboration with the
group of Diane Braguer
of the Aix-Marseille University, France.
Details of distinct effects on microtubule biology are presented
(poster/abstract #422). These show that 
BAL27862 blocks tumor cell
division by altering microtubule dynamics in a unique
way as compared
to conventional microtubule-targeting agents. 
Dr. Laurenz Kellenberger, Basilea's Chief Scientific Officer,
commented: "Resistance against established drugs is a major challenge
in cancer therapy and necessitates the development of new oncology
drugs with novel mechanisms of action to overcome such resistance.
The dual mode of action of BAL101553, attacking tumor cells that are
resistant to other agents as well as disrupting
blood vessels of the
tumor underlines its promising profile as a potential new
agent for
the treatment of refractory human cancers."
