 Algeta ASA : Algeta to evaluate novel Targeted Thorium Conjugate (TTC) based
                         on Avipep's Avibody platform

Oslo, Norway, 11 June 2013 - Algeta ASA (OSE: ALGETA) announces a
collaboration with Australian biotechnology company Avipep Pty Ltd to evaluate
a novel Targeted Thorium Conjugate (TTC) based on combining Algeta's
proprietary thorium-227 alpha-pharmaceutical payload with an Avibody^TM from
Avipep that targets a number of different solid tumor types.
Under the terms of the agreement, Avipep will provide access to a proprietary
Avibody, a next-generation antibody fragment, and Algeta will provide access
to chelation and conjugation technologies, as well as to its alpha
particle-emitting payload thorium-227. Both companies will contribute
financially to the collaboration, which is expected to last for up to one year
initially with the option for further cooperation thereafter. No further terms
have been disclosed.

Thomas Ramdahl,  Executive  Vice President  and  Chief Technology  Officer  at 
Algeta, said: "This  TTC evaluation agreement  is a further  step towards  our 
goal   of   building   an   attractive   pipeline   of   thorium-based   alpha 
pharmaceuticals.  Avivep's  Avibody  has  shown  excellent  tumor   localizing 
properties in model systems and we hope that when armed with our highly potent
thorium-227 payload this novel TTC will offer maximum therapeutic benefit."

About the Algeta TTC Platform

Algeta is evaluating the potential utility of alpha-particle emitting elements
in the  treatment of  cancer. Previous  studies^[i] 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),  potentially  minimizing  off-target 
effects. 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.  Algeta 
intends to evaluate TTCs in a broad range of cancer types to determine whether
the TTC platform could  offer 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.

About Avipep Pty Ltd

Avipep is  a privately  owned biotechnology  company developing  ADCs for  the 
treatment of cancer. Avipep's  proprietary Avibody^TM products are  engineered 
antibody related  proteins that  can deliver  either cancer-killing  drugs  or 
cancer-imaging agents  directly and  specifically to  tumours. Antibodies  are 
natural proteins in the body's immune  system that can target cancer cells  by 
binding to specific molecules on the cancer-cell surface. Avibody^TM  products 
leverage the  targeting  capacity of  natural  antibodies but  are  tuned  for 
improved tumour targeting  and in-vivo  performance. To date  the Company  has 
generated pre-clinical animal results that suggest the exciting potential  for 
the approach.  For further  information  about Avipep,  visit its  website  at
