Cell Therapeutics Spin-off to Use Genetic Technology to Develop Biopharmaceuticals
News Feb 13, 2007
Cell Therapeutics, Inc. (CTI) has announced that it plans to form a new spin-off company, Aequus BioPharma, Inc. to develop a Genetic Polymer™ technology that was created at CTI to speed the manufacture, development and commercialization of biopharmaceuticals including follow-on biologics or so-called biosimilars.
"Pharmaceutical companies and regulatory agencies need to bring the cutting-edge benefits of biotech drugs to patients as quickly, safely and at the lowest cost possible," said CTI's President and CEO, James A. Bianco, M.D.
"A key pitfall of protein therapeutics has been the relatively short plasma life of these types of drugs, which leads to the need for frequent injections and higher associated costs for therapies.
Aequus BioPharma will utilize the Genetic Polymer technology, discovered at CTI, which we expect to extend the plasma half-life of therapeutic proteins and provide a potentially less expensive, streamlined development pathway for next generation biologics like Neulasta® or Aranesp®."
"In addition to its application in producing lower cost follow-on biologics, we believe this recombinant technology might be utilized to develop novel biologics and also deliver small inhibitors of RNA (siRNA), to their cellular targets in a wide array of malignant, inflammatory, or infectious diseases.” noted Bianco.
“We have begun recruiting a scientific and management team, including former members of the Immunex-Enbrel management team, that will have the requisite experience in protein therapeutic development and will take the lead on this new venture to speed follow-on biologics to market and patients," Bianco continued.
The Genetic Polymer technology can be used with multiple molecules, which may eliminate the need to develop individualized technology for extending the plasma half-life of each biopharmaceutical.
The Genetic Polymer technology is a recombinant DNA process that ligates a secretion sequence with a biologically active protein sequence and a poly-amino acid sequence resulting in a patentable gene.
CTI believes that expression in traditional mammalian cell systems will allow for the production of a biologic protein with prolonged plasma half-life, but without the requirement for further chemical modifications subsequent to protein expression, thus potentially speeding the manufacturing process and lowering the cost of goods.
The Company believes this proprietary recombinant Genetic Polymer technology creates compositions of matter and will allow for the manufacture and sale of protein biologics like G-CSF or EPO without infringing on the patents of other companies with competing technologies as well as allowing for more convenient dosing.
CTI believes it has demonstrated a preliminary proof of principle of the Genetic Polymer technology and Aequus BioPharma is anticipated to generate additional experimental data to validate the technology. The first biologics the Company plans to move into preclinical study include a long-acting G-CSF and EPO biosimilar.
