Takeda Cambridge in Second Deal to Expand Use of Dimerix’s GPCR-HIT Platform

PERTH, Australia, 13 April, 2011 – Dimerix Bioscience Pty Ltd today announced that it has entered into a second research program with Takeda Cambridge Limited, a UK based subsidiary of Takeda Pharmaceutical Company Limited, Japan’s largest pharmaceutical company. This new program is in addition to the continuing research program announced on 15 April 2010.

Dimerix is a pre-clinical stage product company developing a pipeline of ’best in class’ lead products with highly specific activity and with reduced risk of off-target effects. Under the new agreement, Dimerix will continue to use its GPCR-HIT platform and leading insights into the ability of G Protein-Coupled Receptors (GPCRs) to form complexes, called heteromers, to work with additional undisclosed GPCRs of interest to Takeda. The outcomes of the new and current programs will feed into Takeda Cambridge’s drug discovery capabilities.

Mark Carlton, President of Takeda Cambridge Limited said: “We are impressed by Dimerix’s achievements over the last 12 months and with the depth of information we have obtained by accessing the power of their GPCR-HIT platform. We have seen that the insights generated using GPCR-HIT provide us with an important extension to our GPCR drug discovery efforts. We are very pleased to be able to expand our efforts with Dimerix.”

Tim Grogan, CEO of Dimerix, said: “We are very pleased with this further expansion of our relationship with Takeda Cambridge. The relevance of our GPCR-HIT platform to the drug discovery and development process and our insights into the formation of complexes between G Protein-Coupled Receptors have been recognized again through this partnership with Takeda Cambridge.”

About GPCRs and Dimerix’ GPCR-HIT Platform:
Dimerix’ proprietary G Protein-Coupled Receptor Heteromer Identification Technology (GPCR-HIT) platform is used to identify complexes formed by GPCRs known as GPCR heteromers. The platform is also used to screen for and to profile compounds that interact with GPCR heteromers resulting in heteromer-selective or biased pharmacology. Use of GPCR-HIT significantly expands the scope of GPCR-based drug discovery and development through the identification of compounds having biased intracellular signaling that is mediated through the GPCR heteromers.

The technology can be applied at various stages of drug development including screening for leads and profiling of compounds, including profiling for potential toxicity or other side effects of compounds that are believed to act through monomeric GPCRs. It also has utility in drug re-positioning and new indication discovery.

Dimerix’s CSO, A/Prof. Kevin Pfleger, Recognized in NHMRC ‘10 of the Best Research Projects 2010’

Dimerix is pleased to announce that on 9 February 2011 The Hon. Mark Butler MP, Minister for Mental Health and Ageing, announced that Dimerix’s CSO, A/Prof. Kevin Pfleger, has been recognized in the ‘10 of the Best’ Research Projects 2010’ published by Australia’s National Health and Medical Research Council.

This publication recognizes A/Prof. Pfleger’s work on improving our understanding of how G protein coupled receptors (GPCRs) operate, with the benefit of enabling the development of better drugs with fewer side effects.

A new method to investigate interactions between GPCRs, known as the ‘GPCR-HIT’ technology, was invented by A/Prof. Pfleger and co-workers at the Western Australian Institute for Medical Research and the University of Western Australia. This technology, being commercialized by Dimerix, and the group’s deep knowledge of the complexes formed by many GPCRs, known as ‘GPCR heteromers’ lies at the heart of this capability.

Details of the NHMRC ‘10 of the Best Research Projects in 2010’ are available here.



GPCR-HIT Technology on the Cover of ASSAY and Drug Development Technologies Journal – February 2011

Dimerix is pleased to announce that its GPCR-HIT technology is featured on the front cover of the February 2011 issue of the journal ASSAY and Drug Development Technologies.

The article ‘Application of G Protein-Coupled Receptor-Heteromer Identification Technology to Monitor β-Arrestin Recruitment to G Protein-Coupled Receptor Heteromers, See HB, Seeber RM, Kocan M, Eidne KA, Pfleger KD. Assay Drug Dev Technol. 2011 Feb;9(1):21-30’ can be accessed free of charge from here.



New Publication: Application of G Protein-Coupled Receptor-Heteromer Identification Technology to Monitor β-Arrestin Recruitment to G Protein-Coupled Receptor Heteromers

This publication details use of the G Protein-Coupled Receptor Heteromer Identification technology (GPCR-HIT) to profile three previously characterized GPCR heteromers, the chemokine receptor heteromers CCR2-CCR5 and CCR2-CXCR4, as well as the angiotensin II receptor type 1-bradykinin receptor type 2 heteromer.

This work illustrates the profiling capability and specificity of GPCR-HIT and is now available free online here.

This publication is by Heng See, Ruth Seeber, Martina Kocan, Karin Eidne and Kevin Pfleger of the Western Australian Institute for Medical Research, University of Western Australia Centre for Medical Research.
