LEXINGTON, Mass., Feb. 28, 2013 (GLOBE NEWSWIRE) -- Agenus Inc. (Nasdaq:AGEN), a biotechnology
company working to develop novel immunology based treatments for cancers and infectious diseases,
today announced its financial results and business highlights for the fourth quarter and year
ended December 31, 2012.

The company reported a net loss attributable to common stockholders of $5.6 million, or $0.23 per
share, basic and diluted, for the fourth quarter of 2012, compared with a net loss attributable to
common stockholders in the fourth quarter of 2011 of $6.2 million, or $0.29 per share, basic and

For the year ended December 31, 2012, the company incurred a net loss attributable to common
stockholders of $12.1 million, or $0.51 per share, basic and diluted, compared with a net loss
attributable to common stockholders of $24.1 million, or $1.21 per share, basic and diluted, for
the comparable period in 2011. The decreased net loss for the twelve months ended December 31,
2012, compared to the same period in 2011, is directly related to the revenue generated of $13.4
million during the first quarter of 2012 primarily due to the one-time payments received through
an expanded agreement with GlaxoSmithKline (GSK), and through a license of non-core technologies.

Cash provided by operating activities for the year ended December 31, 2012 was $1.0 million
compared to cash used in operating activities of $16.2 million for the same period in 2011. Cash
and cash equivalents were $21.5 million as of December 31, 2012.

"Last year we saw significant progress in both our core technology areas, which is expected to
lead to the announcement of significant milestones this year. These include GSK's Phase 3 data
readouts of the MAGE-A3 cancer immunotherapeutic vaccine candidates for melanoma and non-small
cell lung cancer and our Phase 2 data readout for HerpV, a therapeutic vaccine candidate to treat
genital herpes," said Garo H. Armen, Ph.D., chairman and CEO of Agenus. "We believe that
successful outcomes, particularly for the Phase 3 programs, could lead to a paradigm shift in the
way patients are treated in the future and make therapeutic vaccines a larger focus for the
pharmaceutical and biotech industries."

Highlights for 2012

* In November, the second complete set of results from the Phase 3 trial of GSK's RTS,S malaria
vaccine candidate (also known as Mosquirix™), which contains Agenus' QS-21 Stimulon adjuvant®1
(QS-21 Stimulon), were published online in the New England Journal of Medicine. In this trial,
infants (aged 6-12 weeks at first vaccination) receiving the RTS,S vaccine candidate experienced
one-third fewer episodes of both clinical and severe malaria and experienced similar reactions to
the injection when compared to those who received the control meningococcal C conjugate vaccine.
Both co-primary endpoints in the large ongoing efficacy trial were met.
* In October, the company began a Phase 2 randomized, double-blind, multicenter study for HerpV, a
recombinant "off-the-shelf" therapeutic vaccine candidate for the treatment of genital herpes in
herpes simplex virus 2 (HSV-2) positive subjects. HerpV contains QS-21 Stimulon. The study
designated as protocol C-400-02 has recently completed enrollment and data results are expected
during the fourth quarter of 2013. The primary aim of the study is to test the biological efficacy
of the HerpV vaccine as measured by effect on genital HSV-2 viral shedding. 
* In August, data from the Phase 1 trial for Prophage Series G-200 (HSPPC-96; vitespen) were
published by Clinical Cancer Research in an article titled, "Individual patient-specific immunity
against high-grade glioma after vaccination with autologous tumor derived peptides bound to the 96
KD chaperone protein." This data showed that a tumor specific immune response to peptides bound to
gp96 can be generated with autologous HSPPC-96 derived from glioblastoma (GBM) patients undergoing
surgical resection and the observations provide evidence for a general mechanism to elicit
individual patient-specific immune responses that appear to correlate with clinical outcome. 
* In July, GSK's herpes zoster vaccine candidate (HZ/su), which contains QS-21 Stimulon as a
component of GSK's adjuvant system, commenced a global, randomized, placebo-controlled Phase 3
clinical trial for the prevention of shingles (herpes zoster) in immunocompromised patients. This
study will include approximately 200 clinical sites and enroll more than 1,400 patients 18 years
of age or older undergoing hematopoietic stem cell transplantation (HCT). The immunocompromised
study represents the continuation of a Phase 3 clinical program that began in August 2010, which
includes over 30,000 adult patients.
* In June, Agenus met the qualifications to join the broad-market Russell 3000®Index, Russell
2000® Index, Russell Global Index, and Russell Microcap® Index.
* In March, GSK and Agenus amended the QS-21 Stimulon license and manufacturing agreement to
include additional rights for the use of Agenus' proprietary QS-21 Stimulon in GSK adjuvant
systems. In addition, Agenus agreed to grant GSK the first right to negotiate for the purchase of
Agenus or certain of its assets. Under the terms of the agreement, GSK paid Agenus a
non-refundable payment of $9 million, of which $2.5 million is creditable against future
manufacturing technology transfer royalty payments. The agreement also included royalty payments
for an undisclosed indication upon commercialization of a vaccine product.

Between Agenus and its partners, a total of 19 vaccine programs are in clinical development of
which 17 contain QS-21 Stimulon. They include, but are not limited to:

* Phase 3: GSK's RTS,S for malaria2
* Phase 3: GSK's MAGE-A3 cancer immunotherapy for selected patients with resected melanoma2
* Phase 3: GSK's MAGE-A3 cancer immunotherapy for selected patients with resected non-small cell
lung cancer2
* Phase 3: GSK's HZ/su for shingles2
* Phase 2: Janssen's  ACC-001 for Alzheimer's disease

Agenus' pipeline programs include:

* Phase 2: HerpV (contains QS-21 Stimulon) for genital herpes
* Phase 2: Prophage Series G-100 for newly diagnosed glioma
* Phase 2: Prophage Series G-200 for recurrent glioma

Saponin Platform: QS-21 Stimulon



Agenus' QS-21 Stimulon adjuvant is one of the most widely tested vaccine adjuvants under
development. QS-21 Stimulon is designed to strengthen the body's immune response to a vaccine's
antigen, thus making it more effective. QS-21 Stimulon is a key component in the development of
investigational preventive vaccine formulations across a wide variety of infectious diseases, and
appears to play an important role for several investigational therapeutic vaccines intended to
treat cancer and degenerative disorders. Licensees of QS-21 Stimulon include GSK and Janssen
Alzheimer Immunotherapy. Agenus is generally entitled to receive milestone payments as QS-21
Stimulon-containing programs advance, as well as royalties for 10 years after commercial launch,
with some exceptions.

Heat Shock Protein Platform (HSP): Recombinant Series HerpV

HerpV is a recombinant therapeutic vaccine candidate for the treatment of genital herpes, which is
caused by the herpes simplex virus-2 (HSV-2).  HerpV is the most clinically advanced HSV-2
therapeutic vaccine and is currently in a Phase 2 randomized, double-blind, multicenter study. 
The vaccine is based on Agenus' HSP platform technology, and contains Agenus' proprietary QS-21
Stimulon adjuvant.  

HerpV consists of recombinant human heat shock protein-70 complexed with 32 distinct 35-mer
synthetic peptides from the HSV-2 proteome. This broad spectrum of herpes antigens is intended to
allow for more accurate immune targeting and surveillance, reducing the likelihood of immune
escape. Further, the diversity of antigens in HerpV increases the chance of providing efficacy for
a wide segment of the patient population.

In a four-arm, Phase 1 study, 35 HSV-2 seropositive patients received HerpV (designated in the
study as AG-707 plus QS-21), AG-707, QS-21 alone, or placebo. Patients received three treatments
at two-week intervals. The vaccine was generally well tolerated, with injection site pain as the
most common reported adverse event. All patients who received HerpV and were evaluable for immune
response showed a statistically significant CD4+ T cell response (100%; 7/7) to HSV-2 antigens as
detected by IFNγ Elispot, and the majority of those patients demonstrated a CD8+ T cell response
(75%; 6/8). This study was published in the scientific journal Vaccine.

Heat Shock Protein Platform( HSP): Prophage Series Cancer Vaccines

Derived from each individual's tumor, Prophage Series vaccines contain the 'antigenic fingerprint'
of the patient's particular cancer and are designed to reprogram the body's immune system to
target only cancer cells bearing this fingerprint. Prophage Series vaccines, based on our HSP
platform technology, are intended to leave healthy tissue unaffected and limit the debilitating
side effects typically associated with traditional cancer treatments such as chemotherapy and
radiation therapy. The Prophage G Series vaccines are currently being studied in two different
settings of glioma: newly diagnosed and recurrent disease. 

The Cancer Therapy Evaluation Program (CTEP) of the National Cancer Institute (NCI) approved a
study of the Prophage Series G-200 vaccine in a large, randomized Phase 2 trial in combination
with Avastin® (bevacizumab; Genentech/Roche) in patients with surgically resectable recurrent GBM.
The study will be sponsored by the Alliance for Clinical Trials in Oncology, an NCI cooperative
group. This trial will investigate the combination of G-200 and Avastin in a three-arm randomized
study of approximately 220 patients with surgically resectable recurrent GBM. The study will
compare efficacy of G-200 given with Avastin either concomitantly or at progression, versus
Avastin alone, in the therapy of surgically resectable recurrent GBM. This study is anticipated to
begin enrolling patients during the first half of 2013.

In addition to the recurrent GBM study with G-200, a Phase 2 trial testing the Prophage Series
G-100 vaccine in patients with newly diagnosed glioma is underway. In this trial, G-100 is being
used with the standard of care, which includes Temodar® (Merck; temozolomide) and radiation. It is
believed that the efficacy of G-100 could potentially be enhanced through this combination
regimen. Preliminary findings from this study will be presented in a plenary session of a major
medical meeting in early May 2013.
