Argos Therapeutics Announces Initiation of Personalized Melanoma Vaccine Trial
Company Expands its Clinical Trial Activities into New Therapeutic Area
Durham, NC- April 6, 2005 - Immunotherapy pioneer Argos Therapeutics has announced the start of a clinical trial using a novel personalized
melanoma vaccine based on the company’s proprietary technology. The product is made from the patient’s own tumor RNA and immune cells and is the first of its kind to
be developed for melanoma. This investigator-sponsored trial marks an expansion by the company into a second form of cancer. Studies will test Argos’ RNA-loaded autologous
dendritic cell vaccine among patients with Stage IV melanoma. The trial will be conducted at the University Hospital of Erlangen in Erlangen, Germany.
“Our expertise in dendritic cell biology is enabling the development of new therapies to treat cancer, infectious diseases, autoimmune disorders, and transplantation rejection.
Our personalized vaccines have the ability to trigger an individual’s immune system to fight the invading disease,” said Clint G. Dederick, chairman and CEO of Argos Therapeutics.
“The melanoma trial extends Argos’ vaccine technology to treat yet another type of cancer. Our goal as a company is to make more effective and tolerable treatment options
available to patients.”
Argos’ RNA-loaded dendritic cell vaccine is currently in a Phase I/II corporate-sponsored clinical trial for renal (kidney) cell cancer at five sites across the United
States and Canada. According to Lothar Finke, M.D., chief medical officer and vice president, regulatory affairs for Argos, the company is applying the same technology
and process to the melanoma trial.
“By using all of the patient’s tumor antigens to create a personalized therapeutic treatment, we are able to harness the ability of that patient’s immune system to fight
the disease,” said Dr. Finke. “This approach differs fundamentally from other cancer vaccines in that it targets tumor antigens unique to each patient,
bypassing the requirement to know the identity of and characterize those antigens. This technology is applicable to all types of cancer and allows expansion into new
indications without reinventing the manufacturing process each time.”
To create the personalized vaccine, Argos scientists’ pair dendritic cells from the patient’s body with RNA amplified from the patient’s tumor,
thereby making it specific to each person’s cancer. The vaccine is then put back into the patient’s body and stimulates the immune system to recognize and fight the
cancer — in this case — melanoma. With this approach, a large number of vaccine doses can be prepared from a single manufacturing run and only a small tumor specimen
“World-wide prevalence of melanoma continues to rise, and new late-stage melanoma treatment options are scarce,” said Gerold Schuler, M.D., principle investigator
and Professor of Dermatology and Chairman of the Department of Dermatology, University Hospital of Erlangen. “We look forward to making progress with this personalized
vaccine treatment because there have not been significant advances in medical therapies — or survival — for patients with advanced melanoma in over three decades.”
Cutaneous malignant melanoma, a tumor of the pigment producing cells, is considered to be one of the most aggressive solid tumors. There is no evidence to date that any
available treatment improves survival of melanoma patients with distant metastases. Malignant melanoma shows the highest growth rate of all malignant tumors. During the
last 40 years, incidence has doubled every 10 to 15 years. According to the American Cancer Society, over 59,500 new cases will be reported in 2005 in the United States,
and approximately 7,770 persons are expected to die from melanoma. In Europe, melanoma is the 17th most commonly diagnosed cancer in males and eigth most common in females.
In the year 2000, approximately 26,100 males and 33,300 females were diagnosed with melanomas in Europe, and around 8,300 males and 7,600 females died of cutaneous
malignant melanoma in Europe.
Argos Therapeutics, Inc., formerly Merix Bioscience, is dedicated to becoming a market leader in the field of immunotherapy. By using proprietary technology and proven
therapeutic methods and expertise in dendritic cell biology, Argos is developing the next generation of therapies in the areas of oncology, infectious diseases,
autoimmune disorders and transplantation. Our focus is bringing to market therapeutic options that not only offer new promise for treatment of intractable diseases,
but also an improved safety profile and better patient quality of life during treatment. Please visit us at www.argostherapeutics.com
