Observational Study of Blood Treated With Cytolin

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01048372
Recruitment Status : Completed
First Posted : January 13, 2010
Last Update Posted : May 21, 2013

Brief Summary:
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.

Condition or disease
HIV Infections

Detailed Description:
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.

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.
Healthy adults without HIV infection.

Primary Outcome Measures :
  1. T cell number and effector functions in Cytolin-treated blood harvested from HIV infected individuals. [ Time Frame: Entry, 3 months, 6 months ]

Secondary Outcome Measures :
  1. In-vitro suppression of viral replication following Cytolin treatment of blood harvested from HIV infected individuals. [ Time Frame: Entry, 3 months, 6 months ]
