Agenus to Present at Windhover's Therapeutic Area Partnerships Conference
- Agenus' HerpV Named One of the "2012 Top Programs to Watch" by Windhover
LEXINGTON, Mass., Nov. 26, 2012 (GLOBE NEWSWIRE) -- Agenus Inc. (Nasdaq:AGEN), a developer of therapeutic vaccines for cancer and infectious diseases, today announced that Cristina Musselli, MD, Ph.D, Senior Director of Preclinical Development and Translational Medicine at Agenus, will be presenting at Windhover's Therapeutic Area Partnerships Conference on Thursday, November 29, 2012. The conference will be held at the Westin Copley Place in Boston, MA.
Dr. Musselli will present an overview of HerpV, a recombinant "off-the-shelf" therapeutic vaccine candidate in Phase 2 clinical development for the treatment of genital herpes in Herpes Simplex Virus 2 (HSV-2) positive subjects. HerpV contains Agenus' QS-21 Stimulon®* adjuvant, which is currently being studied in 17 clinical programs.
About Recombinant Series HerpV
The HerpV Phase 2 study (designated as protocol C-400-02) plans to enroll 75 HSV-2 positive subjects who have a history of frequent disease recurrences. The study, which was initiated in late October 2012, has already screened over 25% of the needed subjects. The primary aim of the trial is to test the efficacy of the HerpV vaccine as measured by effect on genital viral shedding after three injections. A booster injection of HerpV will also be given at six months after the initial treatment to evaluate the durability of efficacy. The HerpV Phase 2 study design has been defined by key opinion leaders in the field. Experts in HSV-2 clinical research believe that a reduction in viral shedding, the driving force behind the spread of genital herpes, is an important surrogate for clinical benefit in potentially reducing recurrent outbreaks.
HerpV is a recombinant therapeutic vaccine for the treatment of genital herpes, which is caused by the herpes simplex virus-2 (HSV-2). The vaccine is based on Agenus' Heat Shock Protein platform technology, and is administered with Agenus' proprietary adjuvant 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 is designed to increase 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.
