08:44 EDTHEBHemispherx reports evidence based clinical potential of IFN-alpha
Hemispherx Biopharma announced publication of an article entitled "Emergence of a novel drug resistant H7N9 influenza virus: Evidence based clinical potential of a natural IFN-alpha for infection control and treatment". H7N9 is a recently identified virus associated with high mortality in humans with the potential to emerge as an agent for a global pandemic. New cases of H7N9 have been very recently reported in China, Hong Kong and Taiwan. In vitro tests reported in the new article demonstrated that both oseltamivir and Alferon N have significant inhibitory effect on a neuraminidase inhibitor sensitive H7N9 influenza virus. In contrast, Alferon N, but not Tamiflu, had an inhibitory effect on the neuraminidase resistant Shanghai/1/H7N9 virus. According to the peer-reviewed article, "The novel avian H7N9 influenza virus has caused more than 130 human infections with 43 deaths in China. Because of the lack of existing immunity against H7 subtype influenza viruses in the human population and the absence of a licensed commercial vaccine, antiviral drugs are critical tools for the treatment of infection with this novel H7N9. Both M2-ion channel blockers and neuraminidase inhibitors are used as antiviral drugs for influenza infections of humans. The emerging H7N9 viruses are resistant to the M2-ion channel blockers because of a S31N mutation in the M2 protein; additionally, some H7N9 isolates have gained neuraminidase R292K substitution resulting in broad resistance to neuraminidase inhibitors. In this study we report that Alferon N can inhibit wild type and 292K H7N9 viruses replication in vitro. Since Alferon N is approved for clinical use, this would allow a rapid regulatory approval process for this drug under pandemic threat."

08:39 EDTHEBHemispherx, Bioclones announce strategic alliance
Hemispherx Biopharma announced a strategic alliance to develop multiple projects with Bioclones. Bioclones and Hemispherx concluded strategic discussions in Johannesburg with three principal goals; initiating studies utilizing Ampligen as a potential adjuvant enhancement of Bioclones' therapeutic cancer vaccine, currently in clinical trials in Cape Town, including pre-clinical studies followed, potentially, by a Phase 1 clinical trial; seeking South African Medicine's Control Council approval to conduct trials using Alferon to eradicate the HIV virus in patients highly responsive to anti-retroviral therapy; and initiating a joint effort to obtain commercial registration of both Ampligen and Alferon in the South African markets. The first clinical program builds on the Bioclones patented therapeutic human dendritic cell, or DC, cancer vaccination approach. This invention provides a method of producing mature DCs in vitro, which comprises the step of culturing the immature DCs, thereafter exposing said cells to tumor antigens before administration to patients. The team has successfully obtained the necessary Ethics approval to use Ampligen as an adjuvant in the Bioclones pre-clinical cancer immunotherapy program utilizing patient derived samples. Pre-clinical studies will be directed towards the potential treatment of breast cancer in particular, followed by prostate cancer. These studies are part of the effort to develop patient-specific DC immunotherapy vaccines against breast cancer and prostate cancer, which elicit an immune response that will target and kill cancer cells. Human DCs matured with Ampligen and transfected with autologous tumor-specific mRNA are designed to elicit a potent and autologous tumoricidal antigen-specific cytotoxic response to the cancer.
