Study With CureVac's RNAdjuvant Technology Published In Cancer Immunology, Immunotherapy, Demonstrates Equal Responsiveness Of Blood Cells From Both Hepatocellular Carcinoma (HCC) Patients And Healthy Subjects To The RNA-Based Adjuvant
TUBINGEN, Germany, Dec. 5, 2016 /PRNewswire/ -- CureVac AG today announced that a study with its RNAdjuvant® technology was published in the peer-reviewed journal Cancer Immunology, Immunotherapy. The study, titled "Immunological effects of a novel RNA-based adjuvant in liver cancer patients," by Circelli et al., demonstrated for the first time ever that the company's RNAdjuvant® to be used in a therapeutic cancer vaccine formulation is equally effective on peripheral blood mononuclear cells (PBMCs) from both healthy and hepatocellular carcinoma (HCC) patients. The data were collected in connection with the HEPAVAC project, which is sponsored by the EU.
The study examined the effects of CureVac's RNAdjuvant® technology on PBMCs obtained from eight healthy volunteers and 17 HCC patients, using a multiparametric approach to analyze network dynamics of early immune responses. Treatment with RNAdjuvant® elicited comparable effects on PBMCs of both HCC and healthy subjects, having demonstrated up-regulation of several genes involved in innate and adaptive immune-related pathways.
Luigi Buonaguro, head of the HEPAVAC project, said, "The comparable immunomodulatory effects of RNAdjuvant® in HCC subjects and healthy subjects are extremely relevant in the field of vaccinology, in general, and for the HEPAVAC project, in specific. They strongly support the use of RNAdjuvant® in the HepaVac-101 vaccine formulation and are promising for a significant enhancement of the immunogenicity of the vaccine peptides in vivo. We are really excited about these results."
Ulrike Gnad-Vogt, M.D., CMO of CureVac, stated, "We are extremely pleased about these results and believe they strongly support the phase I/II trial in hepatocellular cancer patients planned by the HEPAVAC consortium. We have previously shown that RNAdjuvant is able to enhance virus neutralizing antibody responses against a licensed rabies vaccine in healthy adults. We now hope to see an induction of potent T cell responses in combination with the HepaVac-101 vaccine in patients with hepatocellular cancer and to contribute to an improved outcome.

About Cancer Immunology, Immunotherapy
Since its inception in 1976, Cancer Immunology, Immunotherapy (CII) has reported significant advances in the field of tumor immunology. The journal serves as a forum for new concepts and advances in basic, translational and clinical cancer immunology and immunotherapy. CII is keen to publish broad-ranging ideas and reviews, results which extend or challenge established paradigms, as well as negative studies which fail to reproduce experiments that support current paradigms, and papers that do succeed in reproducing others' results in different contexts.
About the HEPAVAC project
HEPAVAC aims to develop a highly innovative, novel cancer vaccine approach to address the high unmet medical need of hepatocellular carcinoma (HCC) patients. HCC is the most common primary liver malignancy accounting for about 6% of all new cancer cases diagnosed worldwide (nearly 750,000 new cases/year), and is the third and the fifth leading cause of death from cancer globally in men and women, respectively. Given the current lack of available effective treatments, the overall prognosis for patients with HCC is poor with a dismal 5-year survival rate of approximately 5-6%, making the disease a highly important and relevant target for the development of innovative and novel therapies. In this framework, immunotherapeutic interventions, including cancer vaccines, may represent a novel and effective therapeutic tool.

About CureVac AG
Founded in 2000 as a spin-off from the University of Tbingen in Germany, CureVac is a technology leader in the development of drugs that are based on the molecule Messenger RNA (mRNA). The company generated over more than 16 years a very advanced product pipeline and IP portfolio.
The basic principle of CureVac's proprietary technology is the use of mRNA as a data carrier to instruct the human body to produce its own proteins capable of fighting a wide range of diseases. CureVac's mRNA programs include novel mRNA-based cancer immunotherapies and prophylactic vaccines against infectious diseases (RNActive®), molecular therapies designed to trigger the body's own production of therapeutic proteins (RNArt®), a technology that enables the prolonged expression of functional antibodies and antibody-like proteins from mRNA (RNAntibody®) and a novel, RNA-based adjuvant therapy designed to enhance the immunogenicity of vaccines and proteins (RNAdjuvant®).
Since its inception, CureVac has received approximately $360 million (325 million) in equity investments. CureVac has entered into various collaborations with multinational corporations and organizations, including agreements with Boehringer Ingelheim, Sanofi Pasteur, the Bill & Melinda Gates Foundation and IAVI.
