Agenus genital herpes vaccine succeeds in mid-stage trial

Yangshengtang set up a subsidiary company called Innovax to take potential vaccines through clinical trials to manufacturing. (A) GFP expression showing the extent of HSV-2 MS-GFP spread in representative corneas of mice at 30 and 54 h post-challenge. Consequently, most malaria deaths are mostly in children under five years and in pregnant women. The institute aims to bring together academia and industry in developing and commercializing new vaccines. Though more physiologically relevant to humans, the guinea pig model suffers from a paucity of reagents making it more difficult to conduct in depth immunological analyses. The vaccine trains the immune system to actively and specifically search for and destroy tumor cells. The National Institute of… February 10, 2016.

A preventive HIV vaccine based on a genetically modified whole virus (SAV001-H) has successfully completed Phase 1. It is estimated between 80-90% of all domestic cats possess the virus though many do not ever show the symptoms of herpes. I show the effect of using a 10%, 15% and 20% discount rate in the following table. Median overall survival (OS) of Prophage patients was ~24 mo, and 33% of patients were alive at two years and continue to be followed for survival. Agenus’ HerpV Phase 2 Study to Treat Genital Herpes Completes Enrollment. “There are currently 16 QS-21 containing vaccines in clinical development and we look forward to significant news flow from our partners with pivotal data readouts expected from at least four key clinical programs that incorporate QS-21,” said Garo H. Several guidelines related to treatment and prevention of herpes zoster are available, including the following:.

Tasmanian abalone contain protein being developed for new herpes treatment. Unless you are 100% confident that your partner is risk-free, it is advisable that you use irritant-free protections when you have scrapes, sores, tears or cuts. Treatment – extensive use of Dermovate. This program enables Agenus the technology to rapidly discover and optimize fully-human antibodies against a wide array of molecular targets. Interestingly, unlike antibiotics the bugs (staphylococcus, streptococcus, chicken pox virus, etc.) that were treated with the matching frequencies would not develop resistance. It also infects nearby neurons where the virus sets up latent infections, oscillating between dormancy and outbreaks in genital tissue every few weeks or months. HerpV, a genital herpes vaccine candidate manufactured by the company Agenus, announced Phase II clinical trial results in June 2014.

While they are available in pill form, in some cases, intravenous administration of these drugs may be given. More than half of those vaccinated developed a robust anti-HSV cytotoxic T-cell immune response, and in those patients there was a statistically significant 75 reduction in viral load (P0. The immunocompromised study represents the continuation of a Phase 3 clinical program that began in August 2010, which includes over 30,000 adult patients. Patients received three treatments at two-week intervals. In the Phase 1 study, all patients who were evaluable for immune response and received HerpV 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). QS-21 Stimulon is a saponin extracted from the bark of the Quillaja saponaria tree, an evergreen also known as the soap bark tree. The World Health Organization estimated in 1995 that approximately 21 million people worldwide are infected each year.

Success for either vaccine candidate could end the need for daily antiviral doses. These studies will provide additional information on the candidate vaccine’s safety and ability to stimulate immune responses in populations at high risk of shingles because of the weakening of their immune system. If this didn’t, I rather question it would still be attracting a lot attention — and so many fans, both in the human and animal globe. on 9/30/2016 reported its EPS as $-0.33 with the analysts projecting the EPS of the stock as $-0.34. What Genocea is targeting, CEO Chip Clark told FierceVaccines, is the genital lesion rate and the viral shedding rate, or the rate at which the virus, which lives in nerve cells, makes its way to the skin and physically sheds. Agenus may be a potential takeover target due to its intellectual property and relatively small market capitalization. The securities were offered only by means of a written prospectus and prospectus supplement that form a part of the registration statement.

Herpes genitalis When symptomatic, the typical manifestation of a primary HSV-1 or HSV-2 genital infection is clusters of inflamed papules and vesicles on the outer surface of the genitals resembling cold sores. When it all comes down to it at the end of the day, you have a virus that will never go away completely until a true cure is found for herpes simplex. These medicines block the release of histamine, a substance in the body that is released when an allergic reaction occurs.

The vaccine trains the immune system to actively and specifically search for and destroy tumor cells. (B) Mean ± sem total HSV-2-specific IgG levels in pre-challenge serum, as determined by a flow cytometry-based ABVIC (antibody-binding to virus-infected cell) assay comparing the mean fluorescent intensity of IgG antibody bound to uninfected versus HSV-2-infected test cells (n = 16 per group). It is also conservative in not estimating any booster doses. Survivin-specific T-cells have been shown to target and kill survivin-expressing cancer cells while sparing normal cells. In addition to adaptive immune responses, recent evidence implicates the innate immune system in protection from severe HSV infection. Patients receiving a higher dose of the DPX-Survivac in combination with cyclophosphamide produced immune responses after only one vaccination and generally exhibited higher antigen-specific immunity than those receiving the combination with a lower vaccine dose, suggesting dose-related activity. January 15, 2016.

“Just over a third of the cases could have been prevented had they been vaccinated on time,” lead study author Dr Jason Glanz told Reuters. A late-stage clinical trial for Type 1 diabetes recently failed, according to results published this month in the New England Journal of Medicine. More than 500 million people worldwide have genital herpes, a lifelong, incurable infection that can lead to ugly, painful flare-ups. Cold sores are almost always caused by herpes simplex virus type 1 or HSV-1; genital herpes on the other hand can be caused by HSV-1 or HSV-2. Agenus has full rights to Prophage in these indications. E.B. In these cases the air around the fork is very cold and I have surmised that the mind is attempting to pull the energy out of the local air to bend the fork.

Guberski said. Hemorrhagic fever, the severe form of dengue, was reduced by 88.5%. If you want to use your insurance, please be sure to bring in your insurance information at the time of your visit. At least three million people control the symptoms of herpes depend on what kind of ingredients in Viralprin. Age group analysis of the trial results were published in the New England Journal of Medicine on April 28. Approximately 1500 newborns acquire herpes simplex virus (HSV) infections annually. Oxitec’s plan involves the production of mosquitoes with modified genetic code containing DNA from the herpes simplex virus, E.

I suspect that there is a single motivation for this press release………the only logical reason for putting lipstick on this pig is if Agenus hopes to ask (1) NIH reviewers and/or (2) biomedical investors to support the continued folly of testing the HerpV vaccine in human clinical trials. In this study, the vaccine candidate was generally well tolerated. (‘Multum’) is accurate, up-to-date, and complete, but no guarantee is made to that effect. got a boost Thursday morning after the biotech announced good results in a mid-stage study of a vaccine to treat herpes, the second positive announcement in a month of a vaccine involving a key ingredient made by Agenus. Being able to biochemically target only those cells that are affected by a virus would be epochal to state the least. However, Glaxo announced in early 2012 that women who received the vaccine were actually slightly more likely to eventually become infected than women who received a placebo. If you have not gotten educated about STDs, you are playing with fire.

In January, Incyte Corp inked a deal with Agenus to develop new therapeutics targeting immune system checkpoints. These programs are supported by three separate technology platforms. There are actually 5 vaccines in clinical trials right now (all with therapeutic potential) : The two that were mentioned1. Cash and cash equivalents were $21.5 million as of December 31, 2012. This program includes a global, randomized, placebo-controlled Phase 3 clinical study with the HZ/su vaccine, which contains QS-21, for the prevention of shingles and post-herpetic neuralgia in over 30,000 adult patients. Agenus Inc. The data show that GSK’s HZ/su reduced the risk of shingles (herpes zoster) by 97.2% in adults aged 50 and older, compared to placebo.

In theory, this monovalent vaccine would only address approximately 40 percent of the patient population due to variances in patients’ genetic makeup. In this four-arm Phase 1 study, 35 herpes simplex virus type 2 seropositive patients received the vaccine plus QS-21 (HerpV), vaccine without QS-21, QS-21 alone, or placebo. According to the Centers for Disease Control, genital herpes affects more than 60 million Americans—or 1 in 6 people between ages 14 and 49—with an additional 1.5 million new cases each year.1 This disease normally results in 6 outbreaks per year, but in severe cases more episodes may result.2 The psychosocial consequences of genital herpes are quite significant, as 57 percent of those infected indicated that herpes had interfered with their sexual relationships, 50 percent felt it was difficult to live with genital herpes, and 37 percent felt that herpes had ruined their lives.3 Additionally, ongoing research indicates an increasing resistance to currently available genital herpes treatments.
