Researchers believe they may be a step closer to HIV vaccine

Researchers are hoping they are one step closer to a HIV vaccine – using HIV. At the 6th International AIDS Society Conference on HIV Pathogens, Treatment, and Prevention in Rome, researchers with the Maryland-based VirxSys Corporation announced the findings of their VRX1273 vaccine.

The vaccine is a genetically altered version of SIV, the version of HIV found in non-human primates. Over the course of six months, five infected monkeys were injected with the vaccine three times, while five others were given a placebo vaccine. After 18 months, it was found that 40% of the vaccinated monkeys had very low to undetectable amounts of virus in their bodies.

“We are well on the path to a functional cure, at least in monkeys,” says  Laurent Humeau, VirxSys vice president of  research and development.

“Although this pre-clinical study is modest in terms of size, it is highly unusual to see near non-detectable levels of the virus not only circulating in the blood, but also in the reservoirs where HIV is known to replicate,” said Joep Lange, M.D., Ph.D., professor of medicine at the Academic Medical Center, University of Amsterdam, and head of the Amsterdam Institute of Global Health and Development.

In the monkeys, the vaccine’s effect was sustained two years after the initial vaccination, without the need for any booster shots.

Other researchers have created similar type therapeutic vaccines. In May, Dr. Louis Picker of the Oregon Health and Science University’s Vaccine and Gene Therapy Institute announced a vaccine successful in preventing monkeys from acquiring SIV. Like the VirxSys vaccine, this was a genetically altered virus. In this case, the altered virus was  CMV, from the herpes family.

But making the leap from monkeys to humans is a big step. Therapeutic vaccines "have looked really good in monkeys – but monkeys are not people and SIV is not HIV," said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Disease. "Really good concepts in primates have been duds in people.”

Unlike many antiretroviral drugs on the market,  a therapeutic vaccine such as VRX1273 has the potential to be  a  cost effective way of dealing with HIV. Unlike drugs that are taken for the entire course of a patient's  lifetime, this vaccine has the potential to administered just several times, possibly only once, over the course of a patient's life.

Humeau believes that he and his team are headed in the right direction and hope to start clinical trials in humans as soon as 18 months with approval from the U.S.  Food and Drug Administration.

      Yeah, the world's population would be something like 0.02% higher! The death toll of AIDS is somewhere between traffic accidents and diarrhoeal diseases. I do agree though, we need to do something to slow down the population. Helping infectious individuals greater ability to spread disease throughout the population will end up bad. At the rate we're going, nobody will be able to survive in 100 years without giving a substantial portion of income for medications.

      The over population argument is ultimately a classist and racist one. The reason is the underlying belief that it's the poor (with all their kids) who consume the majority of the resources where the exact opposite is true. Keep thinking though.

      George– that brings up an interesting idea about the entire ethics and impact of medicine. Should we treat diseases thereby increasing ones potential to spread the "bad genetics" to their offspring? Either way you look at it, each generation is genetically weaker and Darwins theory of natural selection becomes twisted.

      the cost of treating an aids patient runs into the hundreds of thousands of dollars. with infection rates int he low single digits in most of the developed world, insurance companies would fall all over themselves if they could protect their clients from ever catching hiv even if the vaccine cost 1000$ a dose. a 1000$ times a billion or so people that could afford it – thats a trillion dollars. what drug company wouldnt want a prodct that could haul in a trillion dollars with a single dose cure for a horrible disease? they wouldnt want to sell a treatment if they could provide a cure.

      I'm going to have to agree with Bob. The OP neglects the fact that the health insurance lobby (when combined with various lobbies of health care providers) is just as influential as the pharmaceutical lobby. Also, remember that the pharmaceutical companies would stand to make massive amounts of money. HIV / AIDS treatment is only expensive for patients with the disease. A vaccine can be marketed and distributed to the population at large. The loss of a few very profitable patients would be counterbalanced by millions, if not billions, of less profitable (but still profitable) masses.

      From what I got from the article, they gave the vaccine to already infected monkeys, not to those not infected with SIV, I would assume that in humans it would work the same way. To me it seems more like a treatment than a vaccine.

      No, 40% showing lower infection rates in a group where only 50% were given the drug means 4 out of 5, not 2 out of 5. The other 5 were given a placebo, which means nothing would have changed for them.

      Victor, It is a myth that the Sun's color is yellow. The Sun's color is actually white, but only when the Sun's ray's pass through the earth's atmosphere do the rays 'appear' to change from white to shades of yellow, therefore we perceive it to be 'yellow' colored.

      Its like a yellow colored paper when seen under blue lighting may 'appear' to become 'green'. But just because that paper 'appears' to be green, does its actual color change from yellow to green? NO. LIkewise, the Sun's original color (white) remains even though we on earth perceive it to be 'yellow'

      There's a good reason for every statement by Dr. Fauci to be pessimistic, because frankly, these are pretty unimpressive results. The ability to get a response what is likely a single strain of SIV in a monkey model is insignificant compared with trying to get a reliable response with people for HIV, of which there are thousand/millions of different circulating strains. Trying to make a good vaccine that will provide protection from all possible HIV strains perhaps simply an exercise in futility. I received my PhD in HIV immunology research, and really, this is no big news. Call me when they've done a clinical trial in people and found good protective benefit, until then, I won't be holding my breath.

    People slam research and say they will stop when it's "not profitable???" Do you have ANY idea how many non-profits and universities working toward curing disease at NO PROFIT? Creating vaccines and medicines for your benefit? What about all the countries with government run healthcare who would give anything to find a cure to lower their cost of treatments by billions of dollars – so the governments of these countries all fun research? They would LOSE billions of dollars by denying treatments. No one is holding cures back. Even at a FOR PROFIT a scientist or biochemist would give up their job and take the cure public to win Nobel prize and a million dollars for finding a cure. You think they'd give that up because their boss said so? And you think even a for profit company would give up the PUBLICITY and stock skyrocketing that would come with finding cures?

    The problem is this is a small biotech company which probably exists from month to month on what little money they can raise. Even though this is amazing data – it is pre-clinical and investors will not want to take a risk, particularly in this financial environment, on pre-clinical data. The NIH needs to support this research. Tony Fauci, head of NIAID, spends millions on trials that show little potential. Remember the Tai vaccine trial? Everyone came out against that huge, very expensive trial on 2 vaccines that had already failed and Dr. Fauci plowed along with no regard wasting tax payers money then tried to spin the data to look like there was benefit until it was realized it was all b.s. Dr. Fauci needs to be replaced with someone who actually wants to end the AIDS pandemic and who will fund research like this, not line his own pockets and revel in the power his position gives him. Why was he not removed when he was found to be a co-owner of the IL-2 patent, a compound he funneled millions into? Then when data such as this is released, instead of providing the funding needed for it to move forward, Fauci ignores it. The AIDS crisis is costing the world billions – it is time to fund and support cure research such as this and put an end to the madness which has become the AIDS crisis.

    Dear conspiracy theorists, with all due respect (it ain't much!) you just don't make sense. Hiding a known AIDS vaccine so people can make more money is a great conspiracy, but not a real idea. Think about it, people must be alive to purchase things. I hate to break it to you, but there's nobody that's buying drugs when they're dead. A much better theory is that there's a cure for a non-fatal disease that's being withheld.

      In any scientific experiment there has to be a control group that has nothing changed. It's how you create a comparison and show how effective a drug is. While it seems highly unlikely, the mere possibility that some other aspect of the monkeys' environment was causing the lowered rates, and not the drug, would negate the evidence. This way, the scientists can say "Look, the control group still has high rates but those that took the drug have low rates," which is a way of proving that the drug is the reason for the lower rates.

      Without a control group it would be too easy for pessimists to say "Maybe they just got better because they have some gene that destroyed the virus coincidentally at the same time that they were given drugs" and dismiss the research. While that seems somewhat ludicrous to the layman, that's how all scientific research is performed. They have to prove 100% that the drug is responsible.

    Conspiracy theory or not, the financial ramifications of a "cure" versus a "treatment" are huge. Curing a disease eliminates the disease and the money making potential of on going treatment for the disease. Make no mistake, pharmaceutical corporations are in the business of making money, not cures. Billions of dollars have been spent on disease research. When was the last time you actually heard of a "cure" for a disease? Forcing people to live longer with their diseases is extremely profitable.

      Smallpox. Look it up. The last case of it was in Africa in I think the 60s or 70s. The vaccine was widely distributed and the disease was exterpated, through the work of Jenner (a white guy, damn those evil white people) and the World Health Organization (damn those white scientists). Smallpox used to be an enormous epidemic, killing millions of Africans every year. It far surpassed hiv in deaths.

      How about antibiotics? Most are cheap, given for a short period of time, and cure infection.

      Or Phenylketonuria, a disease that leads to progressive neurological degradation if untreated (something that would presumably make the health care industry lost of money). Now, simple tests allow it to be cause shortly after birth. It can be treated with simple diet changes (which make the health care industry absolutely no money). The same is true for all of the diseases in this class (aminoacidopathies).

      Or peptic (stomach) ulcers. Treatment used to be very expensive and protracted, but now most can now be cured with simple antibiotic treatment.

    Reading the story, it puts me in mind of the Rabies Vaccine - in that you take it when you suspect infection, not just as a normal course.

    Looking at how Rabies deaths have been all but eliminated, I'd say it's a pretty good course of action.

    Scary thing is that all of the developed (aka "white" and asian) world are experiencing population declines, while Africa is contributing to almost all the world's population growth. They can't even feed themselves, and yet they are popping out children left and right. They don't plan for the future and they don't have any sense– that is why their plight is going to get worse and worse and worse. No doubt, the international (aka "white" and asian) community is going to have to rescue them from their own problems and probably take in millions of those parasites.

    Then, I'll make a religious statement: religious interference with the CDC in the early years allowed HIV to gain a much faster foothold in the US that it would have otherwise managed. If not for the heroic administrators disobeying the White House and secretly diverting funds to what were effective covert public health activities, we'd be even worse off.

    How is this progress for an AIDS vaccine? Humans are not susceptible to SIV so attenuating it doesn't mean anything to us. So they've cured SIV in monkey's...that's great, i guess, but it has nothing to do with HIV in people.

    It is about time we find vaccine that will get rid of HIV. I am so glad that we are a step closer. How many years already? If it wasn't the greed of the pharmaceutical companies, we would probably find one by now. I guess they rather sell anti-viral medicine on a long term basis for more dollars than just one-time vaccine. By the way, for those trying to justify AIDS and over population. You are sick. It is not humane and unacceptable to deprive someone the chance to live as healthy as everyone else. I wonder how you would think about it if you are the one that has the virus or cancer, would you want to given a chance to live? Stop being selfish and ignorant. The fact that you care about earth and the use of its resources, doesn't make you a better being. In fact, we are part of the universe, every living thing, including human and earth are all in it together. The only thing we can control over-population is to educate people to limit their births, not to let people who already live suffer and die. If you truly care about mother Earth and your environment, start by limiting the resources you use yourself and help educating others around you to live responsibly. Get rid of your gas guzzling SUV, don't use plastic bag, stop buying bottled water, eat less, etc.

    Pffft! This sounds oddly like a certain sci-fi movie/novel franchise I know of. Cough cough Planet of the Apes, cough cough. And we all know how that one went.

    The whole world is going down the drain. There will never be a cure because of the money hungry corporations. I bet there is a cure but "big brother" wont give relief. I hate this world. A doctor told me that herpes 1 is common. This whole world sucks!

    yes Bob i do agree with you on the cost of treating HIV. one thing i want to add here is that, i think that may be pharma companies have develop the vaccine but they are not getting it out, all they do is to wait and lunch initial treatments to earn.
    i have also explain this in a post on my blog http://www.surgical-blog.com/ i am not given the link here because webmaster of this blog will consider my comment as spam

    Not everyone can get HIV so I'm not worried about some lesser primate plague.Northern Europeans carry a recessive trait that makes them immune to HIV or have higher resistance with just one copy.

      That is only true for about 1% of "Northern Europeans." 1%.

    This is NOT a cure for HIV. A vaccine is a preventative measure for individuals not currently infected with a viral or bacterial disease. It seems many people not in the scientific fields does not know the difference between vaccines, cures and treatments. A cure is something that completely rids the individual of the disease. A treatment improves the quality of the individuals life by releiving them of the diseases symptoms or slowing the progress of the disease. A vaccine is injecting the individual with a whole or partial protein on the outside of the infectious agent, one which your immune system recognizes already. Your bodies immune system has a memory system that allows it to remember that antigen (foreign protein) that has entered the body. So the next time that infectious agent comes in contact with your bodies immune system it already has the system in place to immediately destroy it. At any rate this is a very difficult vaccine to produce because the way HIV works as a virus and the way vaccines work conflict as well as HIV being a retrovirus mutates at higher rates.

    Aren't placebos so that the subject doesn't know if they received the actual vaccine or not–to see what part of the treatment was influenced by wishful thinking? It's no surprise that 40% had 'very low undetectable amounts of the virus in their body'. I'd be shocked by the monkeys' intelligence if that number was anything more than 50%.
