Researchers are hard at work on new treatments to fight genital herpes. Everyone wants a vaccine but experimental products have had mixed and somewhat discouraging results.
Microbicides are one option scientists are exploring in the search for new genital herpes treatments. Microbicides are chemicals that protect against infection by killing microbes (small organisms such as bacteria and viruses) before they enter the body. Two products that have made some progress tenofovir gel and siRNA nanoparticles, which would be applied to the vagina. Studies show these may be able to kill herpes, as well as some other sexually transmitted viruses, and even reduce the spread of the herpes virus from person to person.
Genital herpes raises lots of questions, whether you've just found out you have it, are trying to manage outbreaks, or have a partner who has it. To help get the answers you need, here are the most important questions you'll want to ask your doctor.
Scientists also are working on new drugs that keep the herpes virus from replicating. To replicate (make copies of itself), a virus has to duplicate its DNA exactly. Scientists hope these new drugs will prevent the virus from doing that.
Clinical Trials: Key to Genital Herpes Research
Although these new genital herpes treatments are just on the horizon, it may be years before any are available to consumers.
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 not only scientifically correct, but also ethically sound. The study volunteers have clearly defined rights, such as the right to drop out of the trial at any time.
While there are risks involved in joining a clinical trial, there may be benefits, too. You might get a new "wonder drug" long before it hits the market. If you're interested, ask your doctor if you could benefit by joining one. Your doctor may know of a trial that is seeking volunteers in your area. The National Institutes of Health also has an online database that you can search. This web site provides detailed information on what's involved in joining a clinical trial.
