Brief Summary:
This is an early phase research study looking at whether an experimental gene transfer LVsh5C46 also known as Cal-1 is safe and if it can protect the immune system from the effects of HIV without the use of antiretroviral drugs
Cal-1 is an experimental gene transfer agent designed to inhibit HIV infection through 2 active parts
1 Removing a protein named CCR5 from bone marrow and white blood cells
2 Producing a protein named C46 on bone marrow and white blood cells

Detailed Description:
It is estimated that 33 million individuals are currently infected with HIV HIVAIDS is a disease that impairs immune function primarily by decreasing CD4 T lymphocytes The progression can be contained by daily dosing with antiretroviral therapy ART but there are side effects that can be treatment limiting and the development of HIV drug resistance can force the physician to modify the ART regimen There are no effective vaccines currently available for HIV
LVsh5C46 also known as Cal-1 is a dual therapeutic self-inactivating lentiviral vector that encodes for both a short hairpin RNA against the HIV-1 co-receptor CCR5 sh5 and a HIV-1 fusion inhibitor C46 and inhibits two processes required for HIV-1 infection
1 Binding of the virus to the cellular CCR5 co-receptor and
2 Fusion of the virus with the host cell
The rationale is that Cal-1 introduced into hematopoietic progenitorstem cells HSPC and mature CD4 T lymphocytes will protect these cells and their progeny cells from HIV-1 infection and its pathogenic sequelae This may provide a continuous means of controlling HIV-1 after a single or infrequent doses thereby decreasing or delaying partially or completely the need for antiretroviral drug therapy
