The first patient with chronic hepatit C infection has started its treatment with Tripeps ChronVac-C® - vaccin.
This is the first time in the world someone vaccineras with one DNA- vaccin against one infektionssjukdom through s.k in-vivo- elektroporering.
The study covers totally twelve patients and three dose groups. Each patient comes that few four ChronVac-C®-vaccinationer obvious with a month's intervals. After last vaccinationen is followed the patients additional during six months
Today's treatments of hepatit C has meagre effect, is expensive and afflicted with significant problem and secondary effects. ChronVac-C® is a treating vaccin against chronic hepatit C infection that, about the now the initiated study shows good results, with considerable fewer btreatments, fewer secondary effects and to substantially lower costs should have good conditions to become first choice, says Tripeps CEO Jan Nilsson.
The study is carried out on Infektionskliniken and Gastrocentrum, bode at Karolinska Universitetssjukhuset in Huddinge, respective Solna in Sweden. The study's central aim is to show that the treatment is safe, but also to evaluate about the treatment can to activate the body's immunsvar and impact on virusproduktionen in the liver.
ChronVac-C® is what man calls a treating vaccin, i.e. one vaccin that is given to persons that already are hostile with HCV, in aim to improve theirs immunsvar against the infection. ChronVac-C® is moreover what man calls a genetic vaccin. That one vaccin is genetic mean that one does not fulfil vaccinsprutan with vaccinet without with the genetic code, dna, for vaccinet. When vaccinet been spurted in in the muscle will dna be taken up of muscle cells that since can convert dna to protein and to produce vaccinet alone so that the body's immunförsvar is activated.
A big problem with this so-called DNA-vaccination, if one only uses a common needle, is that vaccin-DNA usually stays outside the muscle cells and is broken down. DNA-vaccin has however many advantages; they are easy and cheap to produce, they can be stored during long time, and same produktionsanläggning can produce a big number different vaccin. In order to can to use these advantages must one the the loose primary problem, i.e. that muscle cells do not take up DNA-vaccin.
One HCV-infektion in the liver does not activate immunsvaret particularly effective, what can contribute to explaining why so majority becomes chronic wearers. In other word can the last of big value to activate one immunförsvar against some non changeable part of HCV on other place in the body than in the liver. A good place is in the body's muscles there vaccinationer usually happens.
Tripep has getupto a solution these problems through a cooperation with the American company Inovio that is world-leading on so-called in- vivo-elektroporering. This technology, that is carried out with Inovios Medpulser® dna Delivery systems (DDS), mean that one sets cells for short electrical pulser what causes lightly temporary holes (porer) in the cell diaphragm, i.e. the cell's shells. When these holes arise can dna effective to take itself in in the cell. After a short while, the holes are sealed again.
Inovio has now developed the technology so that it can be used in people. The treating doctor gives firstly one injektion of ChronVac-C® in a muscle. Immediate then takes the doctor Medpulser® DDS and for in its four electrode styluses in same area there vaccin-DNA was injected. With Medpulser® DDS on-the-spot is given some short el- pulser and then is the treatment clear. A complete behandlingsomgång will cover four alike treatments with a month's intervals. The hope is that this comes evil to that the body activates one immunsvar that helps to healing out the infection.
The development of ChronVac-C® has been taking place since 1999. The company has can take forward models that show what vaccinet can do. ChronVac-C® can activate B-celler and T-celler. T-celler is they as man today considers to last of biggest importance in order to heal out a chronic infection. Mouse studies have shown that one ChronVac-C®- vaccination activates T-celler that makeacommitmentto in the liver and hits out liver cells that produce HCV-protein, a basic requirement in order to a treating vaccin will function. The combination of ChronVac- C® and Medpulser® DDS was noticed in connection with 2nd Hepatitis C conference in Dublin June 23, 2006, there professor Matti Sällberg presented good results from mouse studies. This was followed during the year of more good results. The company could show that the combination gave origins to T-cellssvar that can makeacommitmentto in the liver and to hit out HCV protein producing liver cells. This is actually one proof-of-concept for the combination of
ChronVac-C® and Medpulser® DDS and precise it that one wants to achieve with a treating vaccination.
2006, one breakthrough sows for ChronVac-C® 2006 has so far meant several breakthroughs for ChronVac-C® and several important objectives within the project has been achieved. In January, the company could announce that one a been included cooperation agreement with it San Diego-baserade the company Inovio for a common clinical development of Chron-Vac-C®. The agreement gives Inovio a may verge electricity in ChronVac-C® and in return gets the company access to Inovios technology for DNA-vaccination on people. During February was delivered GMP-framställt ChronVac-C® from Vecura Ltd and two of Inovios Medpulser® DDS-utrustningar for in-vivo- elektroporering to the company. This meant that it toxikologiska the evaluation of ChronVac-C® immediate could be started. In March 2006 received the company the so far the most important patent for ChronVac- C®. This patent protects it strongly modified and improved hepatit C- virusgenen that is in ChronVac-C®. With this has Tripep itself läkemedelskandidat ChronVac-C® safe in smallest 17 years. Three toxikologiska studies has now been implemented, one for cinema distribution and farmakokinetik, an urgent toxikologisk study and one in order to see effects of repeated administration. These studies were completed during the third and fourth quarter 2006. Analog was put together all necessary documentation for application to ethics committee respective Medical Products Agency in order to a phase I- studie on fresh voluntary will can to be started as soon as possible. In December, the company could submit all documents to Medical Products Agency.

exclusion list in trials include: No cirrohsis, no HIV co-infection

This looks interesting, if only from the technical aspects. The viability is the question, of course, and it's a bit hard for me to fathom why the introduction of a substance that looks like a viral fragment would result in a heightened immune system, when the chronic HCV patient is already inundated with trillions of the actual virus to begin with...
Cheers

Whoa - I just read this one. The exclusion list is daunting, to say the least. Along with the two points you listed, and many other exclusions, two biggies are: treatment naive and low viral load.
Some serious cherry-picking...

I know - you'd think one of these outfits would go for the gusto and take on some of the harder-hit folks, but start-ups are all pretty much wimps ;-)
We just have to hope that one of these new regimens has some really surprising results that can be broadly applied.
Hang in there, kiddo :-)
Love and kissies!

I've got that down to a science. I asked my new BCLD about clinical trials and he knocked that idea down right away because of my high AFP. But he also said I'm "stable" (in body, not mind) and he intends to keep me going until one of these new miracle drugs sweeps the disease away.
Love and kisses back, dude. And thanks. :-)
