Antigenics Announces a Negative Vote From the CHMP on Oncophage(R) Marketing Application in Europe

LONDON--(HSMN NewsFeed)--Antigenics Inc. (NASDAQ: AGEN ) today announced that the Committee for Medicinal Products for Human Use (CHMP), of the European Medicines Agency (EMEA), has verbally informed the Company at an oral meeting to anticipate a negative opinion on the marketing authorization application (MAA) for Oncophage (vitespen) in early-stage, localized renal cell carcinoma (kidney cancer).

Antigenics will evaluate its options, including an appeal of this decision, after the CHMP has formally adopted an opinion at the November 2009 plenary meeting. The patient population for which approval is being sought represents a major unmet medical need. There are no approved drugs in Europe or the United States for the post-surgical treatment of adjuvant kidney cancer, a disease characterized by a high risk of recurrence. Antigenics believes clinically relevant benefits were demonstrated with Oncophage in both recurrence-free survival and overall survival endpoints and that this benefit has persisted for nearly five years.

“With the considerable support of the urology and oncology communities, we will continue to evaluate our options for making Oncophage available to kidney cancer patients in the EU,” said Garo Armen, Chairman and CEO of Antigenics.

About Oncophage

Antigenics has treated nearly 800 patients in clinical trials throughout North America and Europe with Oncophage produced in their commercial facility located in Lexington, Massachusetts. Studies with Oncophage have demonstrated efficacy signals in multiple cancers, including melanoma, glioma, colorectal, pancreatic, renal cell carcinoma, gastric cancer and non-hodgkins lymphoma.

In April 2008, Oncophage was approved in Russia for the adjuvant treatment of kidney cancer patients at intermediate-risk for disease recurrence. Pre-commercial launch activities are ongoing.

Derived from each individual’s tumor, Oncophage contains the ‘antigenic fingerprint’ of the patient’s particular cancer and is designed to reprogram the body’s immune system to target only cancer cells bearing this fingerprint. Oncophage is intended to leave healthy tissue unaffected and limit the debilitating side effects typically associated with traditional cancer treatments such as chemotherapy and radiation therapy. Oncophage has been studied in Phase 3 clinical trials for the treatment of kidney cancer and metastatic melanoma and is currently being investigated in Phase 2 trials in recurrent and newly diagnosed glioma.

Oncophage received fast track and orphan drug designations from the US Food and Drug Administration (FDA) for both kidney cancer and metastatic melanoma as well as orphan drug designation from the EMEA for kidney cancer. In 2009, Oncophage also received orphan drug designations from the FDA and EMEA for glioma.

In April 2009, the World Vaccine Congress named Oncophage as the best therapeutic vaccine.

About Renal Cell Carcinoma

Renal cell carcinoma is the most common type of kidney cancer, accounting for almost 90 percent of all kidney tumors. According to a report in the Annals of Oncology, there were more than 63,000 new cases of RCC diagnosed in 2006 along with 26,000 deaths related to the disease.1 Despite earlier detection, patients with locally advanced disease face a poor prognosis, with a 5-year survival rate of approximately 50 percent due to recurrence of disease. Currently, no approved therapies exist in the EU for use in localized disease.
