Scientific titleA phase I clinical trial of the vaccination of healthy human volunteers against the minor histocompatibility antigen (mHAg) HA-1 using a DNA and MVA 'prime/boost' regimen
Study acronymHA-1
Study hypothesisThe purpose of this vaccine study is to produce immune cells (called T-cells) which can prevent and treat leukaemias.

HA-1 is a cell surface protein expressed only selectively by blood forming cells. It is one of the best targets for the immune system to attack after blood and marrow transplant (HSCT). HSCT treats leukaemias by replacing the patient's diseased blood cells with those from a healthy matched donor. 70% of the general population have the HA-1 protein on their blood cells, the remaining 30% do not and are termed HA-1 negative. HA-1 negative individuals can be immunised against the HA-1 protein by vaccination. Following this, HA-1 specific immune cells, produced by vaccinees, can be used to kill patient cells expressing the HA-1 protein on their surface. During this study we will assess the safety and effectiveness of the HA-1 vaccine. This vaccine has two components – a primer (called pDOM-HA-1) consisting of the DNA for the HA-1 and a booster vaccine (called MVA-HA-1) consisting of the HA-1 DNA attached to a different carrier.
