  • New HIV vaccine?

    I saw this on Che's Facebook feed and thought I'd share it since he doesn't post here any more. If this does pan out, and it looks promising given the results of the first round of human testing, then it would be a major step forward for human health. I'm sure the anti-vaccine people will continue to come up with retarded reasons to not apply medical science though as they always do.

    New HIV Vaccine Proves Successful In Phase 1 Human Trial

    A vaccine for human immunodeficiency virus (HIV) has proved successful in a Phase 1 clinical trial with no adverse effects in human patients, Sumagen Canada Inc. and Western University of Ontario announced today. The vaccine, which was developed by Dr. Chil-Yong Kang and his team, is the first genetically modified, whole-killed vaccine to be approved for testing in humans.
    “We are now prepared to take the next steps towards Phase 2 and Phase 3 clinical trials,” stated Jung-Gee Cho, the CEO of Sumagen Co. Ltd., in a press release. “We are opening the gate to pharmaceutical companies, government, and charity organization for collaboration to be one step closer to the first commercialized HIV vaccine."
    Human Testing

    The clinical trial, which evaluated safety, tolerability, and immune responses, was initiated in March 2012 and completed in August 2013. The study of the vaccine, known as SAV001-H, followed intramuscular administration in HIV-infected, asymptomatic men and women, 18 to 50 years of age. The trial studied the vaccine’s effects on volunteers as compared to a placebo group.
    After receiving the vaccination, volunteers visited test sites on weeks four, six, 12, 18, 26, and 52 for a general physical examination as well as analysis of clinical chemistry, hematology, and urinalysis. Researchers observed no serious adverse events and also found a surprising boost in antibody production, which may forecast success in Phase 2 trials measuring immune response.
    The antibody against p24 capsid antigen increased as much as 64-fold in some vaccinees while the antibody against gp120 surface antigen increased up to eight-fold. P24 is a structural protein that makes up most of the HIV viral core also known as the ‘capsid.’ High levels of p24 are present in the blood serum of newly infected individuals during the short period between infection and seroconversion, making p24 antigen assays useful in diagnosing primary HIV infection. A glycoprotein, gp120, is necessary for attachment to cell surface receptors and also allows for the HIV virus to enter cells.

    Production

    SAV001-H, which was produced at a manufacturing facility in the U.S., is the only HIV vaccine developed in Canada and one of only a few in the world. Sumagen anticipates having the first HIV vaccine approved for market. HIV currently affects more than 34 million people who live with the virus worldwide, according to the World Health Organization. Over the past three decades, HIV has claimed more than 25 million lives.
    Since the virus was characterized in 1983, pharmaceutical companies and academic institutions around the world have attempted, yet consistently failed, to develop a vaccine. What is unique about Kang’s vaccine is its use of a killed-whole HIV-1, which is similar to the vaccines developed for polio, influenza, and rabies. HIV-1 is also genetically engineered; this raises its safety profile and the possibility of it being produced in large quantities.
    Sumagen is a member of Curo Group, a Seoul-based company with subsidiaries or affiliates in financial services, information technology, and other business areas. Sumagen has secured patents for the SAV001 vaccine in more than 70 countries, including the U.S., the European Union, China, India, and South Korea.
    Development of Sumagen’s HIV vaccine has been supported by the government of Canada as well as the Bill and Melinda Gates Foundation.
    Canadian researchers have developed the first genetically modified, whole-killed HIV vaccine, which has successfully passed Phase 1 human trials.


    Way to go Canada and Bill Gates!

      Yeah, phase 1 trials are a dime a dozen. Write back when they pass Phase 2.

              It can't. The universe will not allow it. It has received some form of tacit authentication from Oerdin, and therefore is doomed.

                    was this done on people without hiv?

                    if so, would it help boost the immune systems of people for all sorts of diseases, like cancer?

                      I believe it was.

                        Quick answer: no, antibodies are sort of like puzzle pieces - many, many different ones, only some relevant to any one disease and almost certainly irrelevant to all others.

                        Longer answer: Antibodies are specific to proteins (or other cell elements, but generally proteins). Each cell has some things that can identify it, whether it be a structure on the outside of the cell or something it spits out into the blood/other systems. Some of those actually identify the organism the cell belonged to (and are somewhat consistent across different kinds of cells - this is why organ transplants are hard), some of those are more specific to the kind of cell (a skin cell and a red blood cell would have some different elements, for example). Antibodies are things that stick to these like a puzzle piece on one end, and on the other end have some purpose - whether it's for certain immune system cells to stick to (like a flag, "Hi, please eat this"), or to encourage some activity in the body (say, produce more immune cells!), or sometimes to cause something to happen inside the target cell (say, die!). Point is, the puzzle piece end is different for each antibody.

                        We wouldn't really want to boost the entire immune system, honestly, in 99% of people. Boosting the immune system in a general fashion is (sort of) possible - but it tends to lead to autoimmune diseases, which is what most of the limits on the immune system prevent. Autoimmune diseases are really, really, really nasty because it's your own body fighting them - and the main way to fix them is (surprise) to suppress the immune system generally, which of course means you're more vulnerable to infection. Sigh.

                          Phase I is for safety. Phase II has to show some efficacy. Phase III has to show efficacy and that it is as good as or better than alternatives. Then, comes approval.
