Filter by:The purpose of this study is to evaluate the residual allergenicity of the modified ragweed pollen in Ragweed MATA MPL (modified pollen allergen tyrosine adsorbate + Monophosphoryl Lipid A) by skin prick testing. This is done by a comparison of the wheal response after skin prick testing with different concentrations of aqueous native allergen, modified allergen, modified tyrosine adsorbed allergen, and Ragweed MATA MPL.
Tree MATA (modified pollen allergen tyrosine adsorbate) has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to tree (birch, alder, and hazel) pollen. Different doses of Tree MATA will be administered and immunological changes following this treatment will be assessed.
Ragweed MATAMPL has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to ragweed pollen (hay fever). This novel formulation is designed to provide a vaccine that will be efficacious with only four escalating dose injections administered before the start of the pollen season. In this study, the safety and efficacy of Ragweed MATAMPL will be assessed by exposing allergic subjects to Ragweed pollen in an environmental exposure chamber (EEC). Patient symptomatic response to pollen and patient quality of life in the EEC will be determined.
The safety and tolerability of tyrosine adsorbed ragweed pollen allergoid with monophosphoryl lipid A (MPL) was planned to be evaluated. For this purpose, a total of 4 injections of either increasing doses of the study drug or placebo (tyrosine) was planned to be administered in 7-day intervals to healthy volunteers.
The purpose of this study is to evaluate the residual allergenicity of Tree MATA (modified pollen allergen tyrosine adsorbate) by skin prick testing. This is done by a comparison of the wheal response after skin prick testing with aqueous native and modified allergen, modified tyrosine adsorbed allergen and Tree MATA MPL (modified tyrosine adsorbed + MPL [Monophosphoryl Lipid A]).
The purpose of this study is to evaluate the residual allergenicity of Grass MATA (modified pollen allergen tyrosine adsorbate) by skin prick testing. This is done by a comparison of the wheal response after skin prick testing with aqueous native and modified allergen, modified tyrosine adsorbed allergen and Grass MATA MPL (modified tyrosine adsorbed + MPL).
Grass MATA (modified pollen allergen tyrosine adsorbate) has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to grass and rye pollen. Different doses of Grass MATA will be administered and immunological changes following this treatment will be assessed.
