ARTES in partnership to develop novel hepatitis C vaccine
Langenfeld, Germany: – ARTES Biotechnology technology provider for recombinant protein production has joined forces with Australia’s Burnet Institute to develop a novel, effective vaccine to prevent transmission of hepatitis C virus (HCV).
More than 130 million people globally are carriers of HCV, a blood-borne virus. An HCV vaccine is urgently needed to prevent re-infection in people treated through antiviral therapies and reverse the high global mortality rate from HCV-related liver cirrhosis or liver cancer, estimated by the World Health Organization (WHO) at more than 500,000 people annually.
Combining proprietary technologies
The joint project aims to develop a VLP based vaccine that efficiently presents HCV antigens to prevent hepatitis C infection. It combines Burnet’s proprietary HepSeeVaxDelta3™ technology, developed by Associate Professor Heidi Drummer and colleagues, with ARTES’ proprietary METAVAX® technology for the development of chimeric virus-like particle (VLP) based vaccines. The VLPs will present the novel, modified envelope protein (E2) on its surface, thereby targeting the vaccine to dendritic cells to prime and prepare the immune system to fight against hepatitis C infection.
ARTES’ vaccine development platform METAVAX® in combination with the expression host Hansenula polymorpha (recommended by the WHO for hepatitis B vaccine production) is the preferred tool for the development of affordable vaccines. ARTES’ development platform provides a unique approach to low-cost mass production of safe and effective vaccines.
Safe and low cost vaccine
Managing Director of ARTES, Dr Michael Piontek said his company was excited to join forces with Burnet Institute to develop a much-needed vaccine against hepatitis C.
“HCV poses a significant burden on healthcare systems,” noted Dr. Piontek.
“Access to diagnosis and treatment is limited, especially in endemic countries in Africa and Asia, so there is a strong demand for a safe and low-cost vaccine to prevent hepatitis C infection. This is in line with the aim of the WHO to realize their hepatitis C elimination targets,” Dr. Piontek commented.
“After out-licensing processes for hepatitis B vaccine production worldwide, ARTES is proud to take the next step together with Burnet Institute in fighting another life-threatening hepatitis infection,” he added.
Overcoming critical limitation
Burnet Institute has re-engineered the major HCV viral surface protein E2 to produce the novel HepSeeVaxDelta3™ vaccine. HepSeeVaxDelta3™ can generate high levels of antibodies to block replication of all seven genotypes of HCV in laboratory tests. This major advance offers a potential universal vaccine to prevent HCV infection worldwide.
HepSeeVaxDelta3™ technology overcomes a critical limitation to HCV vaccine development, according to Deputy Head of Burnet’s Centre for Biomedical Research and HCV vaccine team leader, Associate Professor Heidi Drummer.
“The virus that causes HCV has evolved to avoid the immune system so that in natural infection, key immune responses are delayed or distracted by irrelevant targets on the virus. The same is true for conventional vaccine platforms tested previously. The HepSeeVaxDelta3™ component of the vaccine redirects the immune response to make antibodies on the most important targets that prevent infection against the seven circulating HCV genotypes,” Heidi Drummer explained.
