Argos Therapeutics to Present at 36th American Society for Apheresis Annual Meeting

DURHAM, N.C., May 8, 2015 (GLOBE NEWSWIRE) -- Argos Therapeutics Inc. (Nasdaq:ARGS) ("Argos"), a biopharmaceutical company focused on the development and commercialization of fully personalized immunotherapies for the treatment of cancer based on the Arcelis® technology platform, today announced that Christine Fernandez, RN, MSN/Ed, OCN, who currently serves as one of the company's regional oncology medical science liaisons, will present at the 36th American Society for Apheresis (ASFA) Annual Meeting at the Grand Hyatt in San Antonio, Texas held May 6-9, 2015.

Ms. Fernandez will present findings on leukapheresis collection from the ongoing pivotal ADAPT phase 3 clinical trial evaluating AGS-003, Argos's fully personalized immunotherapy for the treatment of metastatic renal cell carcinoma (mRCC). Leukapheresis is a procedure used to collect white blood cells from a patient's blood sample.

"In order to successfully manufacture personalized immunotherapies, such as AGS-003, we require a precise and robust collection of monocytes from patients with mRCC," said Ms. Fernandez. "Based upon our ADAPT trial experience to date, we have generated enough data to create a predictive algorithm and decision pathway to further improve our leukapheresis collection guidelines. Implementation of this algorithm has enabled us to collect a high-quality leukapheresis product in a heterogeneous mRCC population, which consistently delivers multiple years of potential AGS-003 treatment from a single leukapheresis."

The oral presentation will take place during Abstract Session II: Donor and Therapeutic Apheresis from 5-5:15pm CT on Friday, May 8th. The abstract is titled, "Leukapheresis Collection (LC) Insights in Unstimulated Patients with Synchronous Metastatic Renal Cell Carcinoma (mRCC) receiving a Combination of Autologous Immunotherapy (AGS-003) and Sunitinib: From the Ongoing International ADAPT Phase 3 Trial Experience."

About the Arcelis® Technology Platform

Arcelis® is a fully personalized immunotherapy technology that captures mutated and variant antigens that are specific to each patient's disease. It is designed to overcome immunosuppression by producing a durable memory T-cell response without adjuvants that may be associated with toxicity. The technology is potentially applicable to a wide range of different cancers, and is designed to overcome many of the manufacturing and commercialization challenges that have impeded other personalized cancer immunotherapies. The Arcelis® process uses only a small tumor or blood sample and the patient's own dendritic cells, which are collected and optimized following a single leukapheresis procedure. The proprietary process uses RNA isolated from the patient's disease sample to program dendritic cells to target disease specific antigens. The activated, antigen-loaded dendritic cells are then formulated into the patient's plasma and administered via intradermal injection.
