The recently reported study tested the two different herpes vaccine candidates RVx201 and RVx202 by administering them to guinea pigs either vaginally or intradermally. After a 28-day observation period, the researchers found that neither herpes vaccine candidate established latency in the guinea pigs. They also found that all of the guinea pigs survived to the end of the study without developing any HSV-2 related disease or adverse reactions. The study concludes that the two novel herpes vaccine candidates are safe in guinea pigs and hence should be tested for efficacy as a preventative and/or therapeutic herpes vaccine against genital herpes.
The lead author of the group, Jonathan Joyce, said that the results are encouraging and validate the need for continued testing and development of live-attenuated herpes vaccine candidates, which according to him, are historically underdeveloped herpes vaccine types for the treatment and prevention of genital herpes.

If Glycoprotein D Is Needed For Viral Cell Entry How Does A Gd
HSV-2 contains a protein on its surface known as glycoprotein D which it needs to enter host cells. It is also essential for cell-to-cell spread of the virus. If the gD gene is deleted from HSV-2 and the virus is grown using a cell line that provides the HSV-1 gD protein to complement the missing surface protein, a hybrid virus is produced that is restricted to a single cycle of growth. When vaccinated, the gD-1 complemented HSV-2 virus replicates once, however the non-infectious progeny cannot spread from cell to cell as it lacks the gene that codes for glycoprotein D.

Herpes Vaccine Clinical Trials
There are currently both preventive and therapeutic vaccines under development. While the primary focus is on HSV-2, the primary cause of genital infection, HSV-2 vaccines may also have benefits in preventing or treating HSV-1 infection. In addition to work being done in the preclinical stage, there are several vaccines in clinical trials. More information on those listed below and other clinical trials can be found at ClinicalTrials.gov, a resource of the National Library of Medicine.
Phase I
- HSV529: Clinical trials for this HSV-2 vaccine candidate are studying both preventive and therapeutic applications. HSV529 uses a replication-defective mutant virus, which is genetically altered to prevent the virus from replicating. In the first phase, researchers are studying the safety of HSV529 vaccine and the ability of the vaccine to elicit immune responses to HSV-2 including virus-specific antibodies and T cell responses to the virus.
Phase II
For more on the current status of herpes vaccine development, including vaccine candidates in the preclinical phase, see this article prepared for the WHO Product Development Vaccine Advisory Committee.

How Is Herpes Diagnosed
A sample will be taken from a sore and tested to determine whether HSV is present in the lesion, thus confirming the diagnosis. However, a negative result does not rule out herpes. Samples should be taken from new ulcers, where it is more likely to find the virus.
Blood tests are also carried out to determine the presence of antibodies against HSV. This test can determine if the infection is new or a repeat outbreak. It is usually very difficult, if not impossible, to point to the exact moment a person was infected with the virus. If herpes is diagnosed, tests should be carried out to discard other STDs, since they can exist as comorbidities.

Concerns About Potential Toxicities
The Hutch scientists note, however, that the good news is tempered by recent concerns within the gene therapy field about the potential for therapies using AAVs to cause liver and nerve damage.
The toxicity issue has been raised by other gene therapy researchers based on their own experiments. It does not appear to involve the gene-cutting enzymes used in the Hutch herpes studies, where those molecular scissors are performing as expected. Instead, it focuses on the AAVs used to package and transport them.
âAAV vectors in general have been considered quite safe. ⦠However, emerging work has suggested that AAV vectors may not be as fully innocuous as previously assumed,â the Hutch authors wrote in the bioRxiv paper.
They observed liver toxicity in some of their mice, but said it seems to be the result of very high concentrations of AAV, well above what is now known to be needed.
âWe know what the toxic dose is, and we get good results below that,â Jerome said.
The neurotoxicity is potentially more concerning. The Hutch team reported âsubtle evidence of neuronal injuryâ in mice when tissue samples were examined under a powerful microscope. However, they also saw no evidence in those animals of changes in behavior or mobility â such as gait or balance disturbances â after the gene therapy.
A priority in the next round of research will be to solve that mystery and, if necessary, find a way around it. The researchers remain confident the problem is solvable.

How Is The Mode Of Action Of Gd
We think that gD-2 is more promising than other previous vaccine candidates because it provokes a different type of immune response against HSV-1 and HSV-2 that is more effective in preclinical models at clearing virus and preventing reactivation. Vaccination with gD-2 elicits ADCC antibodies that facilitate the killing of infected cells and thereby block viral spread. Other vaccine candidates have induced a response that elicits primarily neutralizing antibodies that attach to free floating virus. However, the herpes virus can still move and spread cell to cell, thereby evading neutralizing antibodies and allowing persistence of the virus and viral reactivation.

The process of introducing a new treatment to the public can be a long one. Before the FDA approves a drug, it must go through rigorous clinical trials, which are divided into three phases. In phase I, researchers try to find out if the drug is safe for people to take. If the drug is deemed safe, it may go on to phase II, when researchers aim to determine if the drug works as it should. They also collect more safety data. In phase III trials, they expand their research to include more patients in more places.
To conduct a clinical trial, scientists need people to participate voluntarily. Clinical trials often involve thousands of patients who volunteer to take the experimental drug. The FDA and an independent review board carefully monitor every aspect of the trial. There are rules the researchers must follow to ensure that their work is scientifically correct and ethically sound. The study volunteers have clearly defined rights, such as the right to drop out of the trial at any time.

Who And Partners Launch A New Online Resource To Advance Sti Vaccine Development
The first online portal on vaccine development for sexually transmitted infections was launched today at the 23rd IUSTI World Congress. The portal, STI Watch contains technically sound and updated information on the most common STIs and the vaccine development status for each.
Despite decades of global efforts to control STIs, which have a major impact on sexual and reproductive health, by promoting healthier sexual behaviours, including increasing condom use, treating people with STI symptoms, and improving access to testingand treatment, global STI rates remain stubbornly high. Innovations are needed in the fight against STIs. The development of safe and effective STI vaccines has the potential to revolutionize the approach to STI prevention.
STI Watch is a collaborative effort between WHO, US National Institute of Allergy and Infectious Diseases and AIDS Vaccine Advocacy Coalition . WHO and NIAID along with other key stakeholders have developed a roadmap for STI vaccine developmentand introduction. The roadmap lays out next steps for accelerating STI vaccine development, including: assessing the public health need and value of new vaccines defining their preferred product characteristics and outlining the pathway to developing,evaluating and licensing the vaccines.
This collaboration was extended to AVAC to create a web-based clearinghouse for STI vaccines in order to raise their profile globally.
What Are Clinical Trials For Hsv 2
Herpes simplex virus is the cause of herpes. There are two types of HSV virus:
- HSV 1cause of cold sores around the mouth
- HSV 2cause of genital herpes
According to WHO, around 417 million people across the globe have an HSV 2 infection, while 140 million have an HSV 1 infection. HSV 2 can cause infections in newborns and also attack people with weak immune systems. A person who has this virus also has a higher chance of getting an HIV infection and spreading it to another person. Due to these great numbers and alarming factors, researchers are looking for a vaccine that could help stop the spread of the virus. This is where clinical trials come in.
HSV 2 clinical trials are medical observations and experiments conducted on volunteers in order to find the best cure for herpes. They are as common as any other clinical trial, and you need to check certain criteria to be able to volunteer in them. The goal of HSV 2 clinical trials is to find a better treatment for herpes and help people who live with it lead better lives. You would be included in experiments and observations specifically made for finding a cure for HSV 2. These can differ depending on the way the facility and researchers find it best to test the treatments.

Why Did Previous Attempts To Develop A Herpes Vaccine Focus On Neutralizing Antibodies
Decades of research in herpes vaccine development have focused primarily on subunit vaccines designed to elicit neutralizing antibodies against one or two viral proteins.6 When incubated with viral particles in vitro, neutralizing antibodies can prevent viral entry into cells. This strategy was effective as a vaccine for agents such as hepatitis B, however it had limited success with other pathogens such as herpes simplex viruses. The rationale for a subunit neutralizing antibody approach to HSV vaccine development emanated from observations that neutralizing antibodies that target viral glycoprotein D are elicited in response to natural human infection. While these antibodies do not prevent establishment of latency or prevent viral reactivation in pre-clinical models, they have been thought to limit the frequency and/or severity of clinical recurrences. Subunit vaccines comprised of recombinant gD alone or in combination with other viral proteins and with various adjuvants elicited high titer neutralizing antibodies and provided variable protection in pre-clinical models but the clinical trial outcomes have been uniformly disappointing.

Assuring Safety Before Human Trials Can Begin
The researchers are performing additional preclinical studies of the therapy in guinea pigs, which, unlike mice, have naturally recurring outbreaks from latent herpes infections. As with the mice, the initial focus of this research is in HSV-1, which is primarily associated with cold sores. However, Fred Hutch researcher Dr. Anna Wald points out that recent studies, including one she published with colleagues at the University of Washington, are hinting at a shift.
HSV-1 is becoming â particularly in first infections for adults under 30 â the leading cause of genital herpes, the more feared condition that has been traditionally associated with HSV-2. Regardless, if the experimental therapy works for HSV-1, the researchers are confident it can be relatively easily adapted to target HSV-2.
Wald, who also heads the Division of Allergy and Infectious Diseases at UW, has been researching vaccines to prevent or treat HSV infection since 1991. She said that Jerome and Aubertâs work is a paradigm shift in the field, because the assumption has been that once a person is infected with a herpesvirus â and there are eight members of that family â it is impossible to get rid of that particular strain.
âIt is a completely novel approach, in which you can take a member of the herpesvirus group and eradicate it from the host. As a proof of principle, the fact that it could be done on even one of them is kind of mind-boggling,â she said.
