Algeta initiates new oncology research program to evaluate the potential of a 
Targeted Thorium Conjugate (TTC) based on
Immunomedics' anti-CD22 monoclonal antibody 
OSLO, NORWAY -- (Marketwire) -- 01/28/13 --  
CD22 is a well-validated target for hematological cancers 
Algeta  ASA (OSE: ALGETA) has initiated a new research  program  to 
evaluate  a  novel  Targeted Thorium Conjugate (TTC) that
Algeta's proprietary thorium-227 alpha-pharmaceutical  payload with
an anti-CD22  monoclonal  antibody  (epratuzumab)  developed  by
Immunomedics, Inc.
Epratuzumab  is a  humanised monoclonal  antibody (mAb)  that binds 
to the CD22
glycoprotein  on the surface of B cells.  Epratuzumab has
been evaluated for the treatment of a variety of hematological
cancers and for autoimmune diseases such
as systemic lupus
erythematosus (SLE). 
Under  the  terms  of  this  agreement, Immunomedics will provide
clinical-grade antibody to Algeta, which has rights to evaluate the
potential of a TTC, linking thorium-227 to  epratuzumab, for the 
treatment of cancer.  Algeta will fund all preclinical  and clinical
development  costs up to  the end of  phase I testing.
successful completion of phase I testing, the parties shall negotiate
for  a license  at Algeta's  request according  to certain
parameters now agreed
between  the companies. Payments  in the first 
year from Algeta to Immunomedics
include  a signature fee,  an
antibody delivery  milestone and payments for cGMP
manufacture. No further details of the agreement are disclosed. 
Thomas Ramdahl, Executive Vice President and Chief Technology Officer
of Algeta,
said:  "The  broad  utility  of  our  proprietary 
thorium-227 payload  and its
potential  to be more  effective at
killing  cancer cells than other therapeutic
payloads  gives Algeta 
a great  opportunity to  build an  extensive pipeline of targeted
cancer therapies. This collaboration brings together Algeta, the
leader in alpha-pharmaceuticals and Immunomedics, a pioneer in
antibody products
and  technologies. A TTC based on  a well-validated
antibody such as epratuzumab
is  an exciting prospect as we work to
achieve our goal of generating a clinical
candidate from the TTC
platform in 2014". 
Algeta's  TTC strat
egy is  based on gaining  access to carefully
selected tumor-targeting  molecules, via in-licensing, collaboration
or via  third parties, to which it links thorium-227 thereby creating
potential new therapeutics. Algeta's
disclosed  TTC programs include
collaborations  with Sanofi and Ablynx, programs
based  on
HER2-targeting (breast/ovarian cancer) and PDGFR-beta-targeting
(anti-angiogenesis)  molecules in-licensed  from Affibody  and two 
programs targeting hematological cancers, including this newly
announced program. 
About Algeta's TTC Platform 
Algeta is evaluating the potential utility of alpha-particle emitting
in the treatment of cancer. Previous studies[1] have
indicated that such elements may have value in treating cancers by
causing double-strand DNA breaks
that trigger cell death, and have
also shown that the effects of alpha-emission are highly localized as
a result of the very short range of the alpha particle (2-10 cell
diameters). Thorium-227 is one alpha-particle emitting element
(radionuclide) that has been selected by Algeta for further
investigation. By
linking thorium-227 to cancer-targeting molecules
such as monoclonal antibodies,
Algeta believes it may be possible to
develop a pipeline of targeted alpha-pharmaceuticals, termed Targeted
Thorium Conjugates, or TTCs. The TTC platform is at an early research
phase in development. Algeta intends to evaluate TTCs in a broad
range of cancer types to determine whether the TTC platform could
advantages over naked (un-armed) antibodies or antibody-drug
conjugate technologies that use cytotoxic drugs (rather than
alpha-emitting elements) as
payloads. Such advantages may include
increased potency, a more localized tumoricidal effect and the
potential to address drug resistance by virtue of the physical action
of the alpha particles.
