Herpes zoster, also known as zoster and shingles, is caused by the reactivation of the varicella-zoster virus (VZV), the same virus that causes varicella (chickenpox).Primary infection with VZV causes varicella. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), announced the launch of phase 1 clinical trials into an investigational genital herpes vaccine, according to an agency press release Friday.
Currently, there is no preventive vaccine for genital herpes, Approximately three-quarters of a million people are infected with herpes simplex virus type 2 (HSV-2) and herpes simplex virus type 1 (HSV-1) annually. The investigational vaccine candidate, called HSV529, will be tested in the trials for safety and the its ability to illicit an immune response.
The clinical trial is expected to enroll 60 adults ages 18 to 40, who will be divided into three groups of 20 participants each. Within each of the three groups, researchers will randomly assign participants to receive three doses (0.5 milliliters each) of the investigational HSV529 vaccine (15 participants) or a saline-based placebo vaccine (five participants). Early in 2012, Glaxo SmithKline pulled the plug on the trials on their vaccine, Simplirix, after it failed clinical trials. HSV-2 is generally transmitted through sexual contact and can spread even when the infected individual shows no symptoms.

A clinical trial in Denmark to fight HIV is the latest attempt to find an elusive cure for the virus.
Danish scientists claim theya€™re on the brink of a a€?promisinga€? breakthrough to cure HIV.
Researchers at the Aarhus University Hospital in Denmark said they're now conducting clinical trials on humans using a a€?novel strategya€? that has worked in lab tests, Londona€™s The Telegraph reported.
The Danish trial uses a treatment that forces the HIV virus from so-called reservoirs it forms in DNA cells, bringing the virus to the surface, according to The Telegraph. Once the virus is exposed, the bodya€™s natural immune system can destroy it with the help of a vaccine. While the procedure appeared to work using human cells in a lab, whether it will prove successful in a human body remains to be seen, said Dr. Fifteen people have been signed up for the trial, which was awarded a new round of funding from the Danish Research Council worth about $2.1 million.
Similar research is being conducted in Britain through a collaboration of five universities focusing on people who only recently were diagnosed with HIV.
Sogaard said that the research in Denmark would be a cure for those already infected, but wouldna€™t prevent HIV or AIDS. Finding a cure a€” one that is also widely accessible and affordable to the public a€” took a hit in the United States when experimental shots failed to reduce the amount of the AIDS virus in the blood, the National Institutes of Health said. Ita€™s a strategy known as a€?prime-boost.a€? A DNA-based vaccine made with genetically engineered HIV material is given to prime the immune system to attack the AIDS virus. The idea: Train immune cells known as T cells to spot and attack the very earliest HIV-infected cells in someonea€™s body. A safety review last week found that slightly more study participants who had received the vaccine later became infected with HIV.
When researchers examined only participants diagnosed after being in the study for at least 28 weeks a€” long enough for the shots to have done their job a€” there were 27 HIV infections among the vaccinated and 21 among the placebo recipients.
The NIH said Thursday that it is stopping vaccinations in the study, known as HVTN 505, but that researchers will continue to study the volunteersa€™ health. Both approaches need continued research funding, said Mitchell Warren of the international AIDS Vaccine Advocacy Coalition. Initial, positive results have been reported for a therapeutic vaccine candidate for treating patients with genital herpes. T cells, a type of white blood cells, generate immune responses to pathogens and are important in controlling infections. Wald and her team presented the initial findings of the first-in-human clinical trial of the novel GEN-003 T cell vaccine Sept. Genocea plans to move into Phase 2 of this trial in 2014 to further evaluate GEN 003’s safety and effectiveness in a larger group of patients. At unpredictable times in those carrying the infection, the herpes virus will come out of hiding and  surface on the genitals, sometimes producing blisters and discomfort, and sometimes arising without any noticeable symptoms.  This surfacing is called viral shedding.
The results also demonstrated that immunization with GEN-003 is associated with activation of T cell immunity. The first-in-human clinical trial was not designed to test whether GEN-003 lessens symptoms or lowers how often a breakout occurs. Genocea developed the proprietary platform ATLAS, which can identify protective T cell antigens in people exposed to a pathogen. The vaccine contains, among other components, a proprietary adjuvant, trademarked Matrix-M. While a herpes cure may be a long way off, a herpes treatment may be getting closer.  A little over 2 years ago, we wrote about Genocea's GEN-003 therapeutic vaccination.


Genocea’s GEN-003 is not a herpes cure but rather a “Therapeutic Vaccination” for the moment. We update the blog every couple of weeks with news, events and other things that may be of interest.

A once-promising vaccine against herpes viruses has failed in a large clinical trial, researchers reported. In prior studies, this herpes simplex vaccine markedly reduced the risk of genital herpes disease in women in so-called serodiscordant couples, in which one partner had the virus and other did not.However, in this study of women who were seronegative for HSV-1 and HSV-2 and representative of the general population, the vaccine had some efficacy in preventing HSV-1 genital disease and infection but not in preventing HSV-2 disease or infection. The vaccine had markedly reduced the risk of genital herpes disease in women in so-called serodiscordant couples, in which one partner had the virus and other did not, according to Robert Belshe, MD, of St.
But in a large study intended to mimic the general population of uninfected women, vaccine efficacy against disease was only 20%, the researchers reported in the Jan. The vaccine showed some efficacy against herpes simplex-1 (HSV-1), but not against herpes simplex-2 (HSV-2), the researchers reported. Since both viruses are common and clinically indistinguishable, Leone said, the vaccine probably would have a limited public health benefit and won't be pursued. He said researchers probably will need to take a "different type of vaccine approach" in order to find something that works against both viruses. In general, HSV-2 is regarded as more worrisome since it tends to recur more than HSV-1 and also is associated with an increased risk of acquiring HIV. In the two earlier clinical trials, among discordant couples, the vaccine showed efficacy of 73% and 74% against genital disease (caused by either virus) among women who did not have antibodies against HSV-1 or HSV-2.
For this study, the researchers enrolled 8,323 women, ages 18 to 30, who did not have antibodies to either virus.
The primary endpoint was occurrence of genital herpes disease due to either HSV-1 or HSV-2. Analysis showed: Overall, the vaccine was just 20% efficacious in preventing genital herpes disease It was 58% efficacious against disease caused by HSV-1 but had no effect against HSV-2 disease Overall, the vaccine protected against infection with an efficacy of 22%, but that was driven by a 35% efficacy against HSV-1 infection. The researchers noted that the findings are "puzzling in view of the previous two studies involving discordant couples" -- both of which showed efficacy against HSV-2. Leone said the difference might be a function of exposure among women in those trials, since by definition their male partners were infected with one of the two viruses.
Such exposure might have led to a cellular immune response even though it was not enough to cause the women to develop antibodies, he said. Interestingly, there were only two cases of HSV-1 disease in those two studies (one in each), the researchers noted, so that it was impossible to evaluate efficacy against that virus. The study was supported by the National Institute of Allergy and Infectious Diseases and by GlaxoSmithKline.

The three vaccinations will occur at study enrollment and again one month and six months later. This depends on the strength and sensitivity of individual immune systems,a€? Sogaard told The Telegraph.
Half received dummy shots, and half received a two-part experimental vaccine developed by the NIH. Then a different vaccine, encasing the same material inside a shell made of a disabled cold virus, acts as a booster shot to strengthen that response. The hope was that the vaccine could either prevent HIV infection, or help those infected anyway to fight it. A 2009 study in Thailand is the only one ever to show a modest success, using a somewhat different prime-boost approach.

This first-in-class, investigational, protein subunit vaccine, GEN-003, is under development by Genocea Biosciences Inc. Anna Wald, University of Washington professor of medicine and laboratory medicine in the School of Medicine and professor of epidemiology in the School of Public Health, is among those leading clinical studies of GEN-003. David Koelle’s lab in the Division of Allergy and Infectious Diseases, Department of Medicine. T cell vaccine research is trying to find safe, effective ways to spur this protective reaction. 12 at a session of the Interscience Conference on Antimicrobials Agents and Chemotherapy in Denver. The infection can provoke recurring episodes of painful genital sores.  An estimated 50 million to 60 million Americans are affected.
In those receiving the vaccine candidate, T cell immune responses increased more than 20 times to one vaccine antigen and more than 10 times to another antigen.  The vaccine candidate also increased neutralizing antibodies to the herpes simplex 2 by five times greater than baseline amounts. However, an exploratory analysis suggested that the interval between the first immunization with GEN-003 and the next recurrence of genital herpes might be longer in those receiving the actual candidate vaccine, rather than the placebo injection. Wald is enrolling women infected with herpes simplex virus 2 in a study to see whether the drug tenofovir, given orally or as a vaginal gel, reduces genital shedding of the virus. The good news is the study is still going on and Genocea has updated their website with some promising information. Or you can return to the last page visited prior to registration and complete your profile later.
The investigational vaccine is being tested among study participants who have previously been infected with HSV to determine if it may pose any safety issues.


Participant safety will be monitored throughout the course of the trial, and researchers will follow participants for six months after they have received their last dose of vaccine. Once in the body, HSV migrates to nerve cells and remains there permanently, where it can reactivate to cause painful sores and blisters.
In addition, Robert is the Editor-in-Chief of the infectious disease news magazine Outbreak News Today. Newer research suggests another approach a€” to try creating powerful antibodies that could work a step earlier than the T-cell attack, before HIV gets inside the first cell. Genocea, located near Boston, is a clinical-stage biopharmaceutical company for the discovery and development of T cell vaccines to prevent and treat infectious diseases. Viral shedding is a marker both of the risk of recurrence and the transmission of infection. The adjuvant has a product that, in previous clinical studies, has been shown to stimulate B and T cell immune responses. Reducing the frequency of viral shedding is the first step to showing that a drug can reduce outbreaks or, potentially, sexual transmission to partners. Research and clinical trials are going on to develop a vaccine or at least try to lessen the symptoms. In an effort to find a cure for herpes, Genocea has received a lot of attention with its GEN-003 vaccine and clinical trials. Leone reported financial links with GlaxoSmithKline, Novartis, Abbott Diagnostics, and Genocea. Blood samples will be used to evaluate the candidate vaccine’s ability to stimulate immune system responses to HSV-2, including production of virus-specific antibodies and T-cell responses. Overall, there were 41 HIV infections in the vaccinated group and 30 among placebo recipients. Tenofovir has been shown in some studies to reduce the risk of acquiring HIV, and in some studies there was also a reduction in the frequency of HSV-2 acquisition, but this is the first time that it is being tested as a drug specifically for HSV-2.

However, second and even third episodes are possible.Clinical FeaturesPeople with herpes zoster most commonly have a rash in one or two adjacent dermatomes (localized zoster).
Disseminated zoster can be difficult to distinguish from varicella.The rash is usually painful, itchy or tingly. Some people may also have headache, photophobia (sensitivity to bright light), and malaise in the prodromal phase.The rash develops into clusters of clear vesicles.
New vesicles continue to form over three to five days and progressively dry and crust over.
Some define PHN as any duration of pain after the rash resolves; others define it as duration of pain for more than 30 days, or for more than 90 days after rash onset.
Approximately 13% (and possibly more) of people 60 years of age and older with herpes zoster will get PHN. Even people who have had herpes zoster should receive the vaccine to help prevent future occurrences of the disease.Herpes zoster vaccine is approved by FDA for people aged 50 years and older.
However, CDC does not recommend routine use of herpes zoster vaccine in people aged 50 through 59 years old. Health care providers considering the herpes zoster vaccine for certain persons aged 50 through 59 years should discuss the risks and benefits of vaccination with their patients. Although the vaccine has short-term efficacy, there have been no long-term studies of vaccine protection in this age group. People who have not had varicella and never received chickenpox vaccine can get infected with VZV from someone with herpes zoster.
If this happens, they are at risk of developing varicella not herpes zoster.The virus spreads when a person has direct contact with the active herpes zoster lesions.
Children who get the varicella vaccine appear to have a lower risk of herpes zoster compared with people who were infected with wild-type VZV.
As a result, all older adults in the United States are at risk for herpes zoster.The reasons why VZV reactivates and causes herpes zoster are not well understood.
However, a person's risk for herpes zoster may increase as their VZV-specific cell-mediated immunity declines.
Almost 1 out of 3 people in the United States will develop herpes zoster during their lifetime.
Almost all the deaths occurred in elderly people or those with compromised or suppressed immune systems. Thus, they are concerned that routine childhood varicella vaccination, recommended in the United States in 1996, could lead to an increase in herpes zoster in adults due to reduced opportunities for being exposed to varicella.
