Hepatitis B
There are 400 million hepatitis B (HBV) patients worldwide. It is estimated that about 100 million of these patients will eventually die from complications directly related to their chronic HBV infection despite available therapies. Current therapies have been associated with several problems including viral resistance, significant toxicities and the lack of a curative response even after many years of therapy.
Our drug is a first-in-class surface antigen release inhibitor. It prevents the release of a viral protein called surface antigen from infected liver cells (hepatocytes). Mounting evidence is now showing that surface antigen acts to suppress the immune response to HBV infection and may allow the infection to be chronically maintained in the liver. The administration of our drug to animals or humans results in a rapid reduction and elimination of surface antigen in the blood. This reduction is associated with a restoration of the immune system’s capability to fight the infection as demonstrated by the development of antibodies against surface antigen. In other words, the removal of surface antigen from the blood gives patients the ability to successfully fight their infection on their own. In addition, because of its mechanism of action, the development of resistance to our drug is very unlikely.
In collaboration with scientists from the University of Adelaide, Australia, REPLICor has tested the antiviral potential of its drug in ducks infected with duck hepatitis B viruses, a recognized animal model that is a good predictor of antiviral activity in human subjects. We have shown that a 4 week daily treatment regimen with our drug was able to result in a curative response in more than half of DHBV-infected ducks treated. This is the first time any such curative response has been achieved in this model and has not been achievable with drugs currently marketed for the treatment of HBV.
Interim clinical data from our phase I/II trial shows that our drug is well tolerated and has substantial antiviral activity in patients suffering from chronic HBV infection. The administration of our drug results in the rapid elimination of surface antigen and the appearance of antibodies in most patients. This is followed by a substantial reduction of viral DNA titers.
Rep9AC 声称他们的临床1期和二期的数据表明此药具有很好的耐受性,这些数据如果不是先前论文中提到的那6个人的话,是不是会有official report?要是有的话并且不是商业机密的话,哪位英文大仙给他们发邮件索要一份吧。 |
