Observational Study of Blood Treated With Cytolin
An Observational Study to Determine the In-vitro Immunologic and Virology Activity of Cytolin
Primary Objective: To determine the mechanism of Cytolin's effect on HIV replication from blood drawn from HIV-positive and HIV-negative individuals after exposure to Cytolin.
The initial phase of this in vitro study regarding the potential mechanisms of action of Cytolin was completed in January 2011. Given the data set to date, a decision has been made to extend the study. The extension will allow the Company to further confirm and extend the initial findings regarding the potential mechanism of action of Cytolin.

HIV Infections
Not Provided
  • Early HIV infection
    HIV infected adults with early evidence of suppressed cell-mediated immunity but whose disease has not progressed far enough to indicate antiretroviral therapy.
  • Control
