Immunotech Laboratories, Inc. (IMMB)
Pursuant to significantly positive results with its patient population targeting full blown AIDS patients, the company has completed numerous clinical contracts with Mexican hospitals to initiate a full blown effort of clinical trial protocol preparation for its HIV/AIDS Vaccine drug candidate. The successful outcome of these efforts will eventually provide the necessary regulatory means for its product’s registration approval in the Republic of Mexico and eventually open a venue to most of the central and South American markets.
Resistance to all commercially available antiretroviral (ARV) agents within all classes has been reported. The occurrence of multi-class resistance remains high, with 20% of infected individuals developing resistance to two or more classes within six years of initiating treatment, and 10% of newly diagnosed infections already resistant to at least one class in the U.S. Multi-class resistance is even more prevalent in disenfranchised patient populations, whose rates of successful adherence to even the most simplified regimens available remains prohibitively low. Inactivated Pepsin Fraction (IPF), like other natural autoantibody based fractionated proteins, has an affinity to pathogenic binding and simultaneously produces effects of immune homeostasis. IPF has shown significant antiretroviral activity via immune stimulatory pathways in vitro, notably helper T1 cells elaborate cytokines INFy, IL-2. These cells selectively promote cell-mediated immune responses that are disadvantageous to viral replication.
IPF appears to modulate helper T1 cells’ expression of elaborate cytokines INFy, IL-2, which selectively promote cell-mediated immune response and subsequently stimulate cytotoxic lymphocytes. These lymphocytes have a prominent role in the host’s immunologic response to HIV infection. Proteins encoded by these pathogens enter the endogenous pathway for antigen presentation and are expressed on the surface of the infected cell as a complex with class l MHC- proteins. IPF appears to present a novel mechanism to reduce viral burden and stimulate immune responses to the virus for patients with significant antiretroviral resistance. Furthermore, the use of IPF with antiretroviral therapy reduces the viral load between two and five log reduction.
