Icon Genetics successfully completes Phase I clinical study with personalized vaccines for treatment of non-Hodgkin's lymphoma
The study was carried out in close cooperation with the group of Professor Maurizio Bendandi (University of Navarra, Spain). Dr. Bendandi's team had previously succeeded in a groundbreaking study with hybridoma-produced vaccines that triggered an immune response to each patient's tumor-specific idiotypic antibody (surface immunoglobulin) in subjects who had previously achieved complete remission with chemotherapy. ICON's study was based on Dr. Bendandi's work and that of other lymphoma researchers, but used plant-based technology to custom-manufacture the vaccines more rapidly and efficiently than is possible by other approaches.
Being the owner of the lymphoma vaccines program upon completion of the study, ICON plans to further develop the product in order to bring this promising new treatment to market.
"Our study followed the original concept of personalized cancer vaccination developed by Professor Ronald Levy at Stanford University. Its successful completion brings the powerful concept of individualized cancer medicines closer to patients," said Yuri Gleba, CEO of ICON. "Completion of this program required resolution of multiple technical and logistical challenges, including manufacture, release and administration of 27 different recombinant proteins in a single clinical trial. It was the first clinical test of the company's magnICON® technology, which required the coordinated efforts of several organizations. Success would not have been possible without the contributions of the many ICON professionals who participated in this project, the leadership and support provided by Dr. John Butler of Bayer Innovation, planning and analytical support from University of Navarra (www.unav.edu), clinical coordination by DAVA Oncology (www.davaonc.com), and the excellent product development and regulatory support provided by DT/Consulting Group (www.dt-cg.com), Bayer HealthCare Pharmaceuticals (http://biotech.bayerhealthcare.com/locations/berkeley.asp) and CBR International (www.cbrintl.com)," Dr. Gleba added.
Dr. Victor Klimyuk, ICON's COO, elaborated: "This study was pivotal for ICON because not only did we confirm the safety and immunogenicity of plant-produced vaccines, we also established a completely scalable manufacturing process. The technoeconomic advantages of our approach to producing individualized products are strikingly superior to conventional methods used to produce biopharmaceuticals. We have found that the magnICON® manufacturing platform is very well-suited for high-throughput processing of multiple small batches containing different molecular compositions, as exemplified by the idiotypic lymphoma vaccines employed in this study."
About idiotype vaccination
Idiotype vaccination is a new type of therapy that has not yet been given regulatory approval. It is referred to as active immunotherapy and, unlike most other biological therapies, is specific to the individual patient. This means that each patient is treated with a product tailored to his or her specific needs. The vaccine consists of an antibody - an immunoglobulin - which is present only on the diseased lymphocytes and not on healthy lymphocytes or other cells in the body. This protein is known as an "idiotype." The goal is to produce an individual drug product for each patient and administer it as a vaccine. The objective of the new therapy is to activate the patient's immune system, enabling the malignant cells to be targeted and destroyed by the body's own defense system with minimal side effects.
About non-Hodgkin's lymphoma
Non-Hodgkin's lymphoma is a type of malignant disease that occurs within the lymphatic system, and it is the fifth most common cause of death due to cancer after breast, prostate, lung, and colon cancer. It originates from lymphocytes, a type of white blood cells. There are two main types of lymphocytes: B lymphocytes and T lymphocytes (also called B-cells and T-cells). Non-Hodgkin's lymphoma can be divided into two general clinical categories: indolent lymphomas, the most common forms of which include follicular lymphomas which tend to grow relatively slowly; and aggressive lymphomas, which include diffuse large B-cell lymphomas (DLBCL), which grow more rapidly. The overall prevalence of NHL in the European Union is approximately 230,000, with an annual incidence of about 70,000 new cases. Follicular lymphoma is one of the most common types of indolent NHL, accounting for 25-30 percent of all NHL lymphomas. It is a type of cancer that can be treated in the short-term but is persistent and ultimately difficult to cure.
