Feb 19th 2020 TAGCyx and GC Pharma has entered into collaborative research and development for conducting various pre-clinical studies of TAGX-0004

February 19 2020: TAGCyx and GC Pharma (formerly known as Green Cross Corporation) has entered into collaborative research and development for conducting various pre-clinical studies of TAGX-0004.

TAGCyx has signed Joint Research and Development Agreement with GC Pharma (KRX: 006280) in relation to pursuing various pre-clinical studies of TAGX-0004, an anti-human vWF DNA aptamer containing proprietary artificial nucleotide.

TAGCyx has invented artificial nucleic acid base pair technology that enables to produce high affinity and selective DNA aptamers “Xenoligo®”, that is regarded to be an alternative to antibody therapeutics.

 

GC Pharma is a biopharmaceutical company that delivers life-saving and life-sustaining protein therapeutics and vaccines. Headquartered in South Korea, GC Pharma is the largest plasma protein product manufacturer in Asia and has been dedicated to quality healthcare solutions more than half a century.

 

TAGX-0004 is an innovative DNA aptamer therapeutics developed by TAGCyx aiming to treat thrombotic disorders such as brain and cardiac infarction, and currently under development for rare disease called acquired thrombotic thrombocytopenic purpura (aTTP).  TAGCyx has accumulated many pharmacological data to date in collaboration with a Japanese leading scientist in the field, Professor Masanori Matsumoto, Nara Medical University.

 

Dr. Chizuko Koseki, Chief Executive Officer of TAGCyx added “Together with GC Pharma, we believe our aptamer will be a key therapeutic option for the patient of aTTP, and eventually for other thrombotic diseases. GC Pharma’s deep insight will realize TAGCyx’ mission to provide an effective treatment to various challenging diseases”.

 

Under the agreement, GC Pharma will fund the development cost for pre-agreed pre-clinical studies, and TAGCyx will conduct the studies with CROs. Under the confidentiality of the agreement, further detail of the research is not disclosed.

 

December 25th 2019 TAGCyx receives milestone payment for collaborative research with HEALIOS K.K.

TAGCyx is pursuing collaborative research with HEALIOS K.K. (CEO: Hardy TS Kagimoto, MD, Head office: Tokyo, listed on Tokyo Stock Exchange Mothers Index: 4593) to generate innovative DNA aptamers for use in regenerative medicine using TAGCyx’ proprietary Xenoligo® platform. We are pleased to disclose that we have reached a milestone in the collaboration and received the relevant milestone payment.

Due to confidentiality obligations in our agreement with Healios, further details are not disclosed.

October 10th 2019: TAGCyx enters into a collaborative aptamer glycosylation research agreement with GlyTech, Inc.

TAGCyx has signed a collaborative research agreement with GlyTech, Inc. (CEO: Hiroaki Asai, Head office: Kyoto) in relation to glycosylation techniques for aptamer therapeutics.
TAGCyx possesses a leading, proprietary, artificial nucleic acid base pair technology, used to produce high affinity and selective “Xenoligo®” DNA aptamers, while GlyTech possesses a unique platform for the production of an extensive variety of highly purified human N-glycans, and the technology to attach them to a specific site on target molecules such as synthetic peptides.
Modifying Xenoligo® with GlyTech’s glycosylation technology is expected to increase the functionality of aptamers and add high value to them.

Dr Chizuko Koseki, Chief Executive Officer of TAGCyx added “We are pleased to enter into a collaboration with GlyTech, bringing together two leading technologies to potentially enhance therapeutics research”.

October 9th 2019 TAGCyx has executed a collaborative antibody-aptamer conjugate research agreement with Chiome Bioscience Inc.

TAGCyx has signed collaborative research agreement with Chiome Bioscience Inc. (CEO: Shigeru Kobayashi, Head office: Tokyo, listed on Tokyo Stock Exchange Mothers Index: 4583) in relation to innovative aptamer therapeutics.
TAGCyx possesses a leading, proprietary, artificial nucleic acid base pair technology (Xenoligo), producing high affinity and selective DNA aptamers “Xenoligo®”, whereas Chiome is pursuing development of unique therapeutic monoclonal antibody(ies).
Conjugating Xenoligo with Chiome’s monoclonal antibodies will generate bispecific molecules that have the potential to further enhance the functionality of potential therapeutic agents.

Dr Chizuko Koseki, Chief Executive Officer of TAGCyx added “we are pleased to enter into a collaboration with Chiome, bringing together 2 leading technologies to potentially enhance therapeutic research”
