Active clinical trials for "Hypersensitivity"

It is believe that ragweed is the primary cause of autumn allergies and 87% of patients with ragweed allergy suffer rhinoconjunctivitis. ToleroMune Ragweed is a novel, synthetic, allergen-derived peptide desensitising vaccine, currently being developed for the treatment of ragweed allergy. This study will look at the efficacy, safety and tolerability of two doses of ToleroMune Ragweed in ragweed allergic subjects following challenge with ragweed in an EEC.

Pralatrexate is a type of antifolate drug which means is restrains the production of folic acid in the body. Folic acids are used by tumors to increase tumor cell growth and division. It is believed that reducing folic acid will hinder the rapid division of tumor cells, their growth and production. Carboplatin is an FDA approved chemotherapy drug for ovarian, fallopian tube and primary peritoneal cancer. Some antifolate drugs are used with other chemotherapy drugs to enhance cancer-fighting characteristics. It is believed that the study drug pralatrexate may improve the anti-tumor effect of carboplatin. In this research study we are looking for the highest dose of pralatrexate that can be given safely in combination with carboplatin.

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 Follow-up Study the Efficacy 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. Patients who previously completed two EEC portions of study Ragweed MATAMPL 204 and who had been treated with either Ragweed MATA MPL or Placebo before the 2005 ragweed season will be enrolled.

This is a randomized, double-blind, double-dummy, placebo-controlled, parallel-group, single center study in subjects with positive histamine skin prick test and a positive RadioAllergoSorbent Test (RAST) (class > 2) to one of the tested standardized allergenic extracts: tree pollen, cat dander, house dust mite, or a mixture of five grass pollens. Subjects will be randomized to desloratadine 5 mg once daily, levocetirizine 5mg once daily, or placebo once daily for 8 days of treatment followed by 11 days of skin testing after discontinuation of the antihistamine treatment phase. The duration of the suppressive effects of desloratadine on cutaneous allergen-induced wheal and flare responses after discontinuation of a one-week treatment will be established.

This is a Phase IIb, multicenter, open-label study available to active (Xolair) and control (placebo) subjects who have completed their final visit (or early termination visit, if applicable) for Study Q2788g, who meet the eligibility criteria of this study, and who provide consent to participate in this study.

The purpose is to find out if Icleen IQAir, HEPA-filter air cleaners with high capacity and pre-set speed functions, have a beneficial effect on patients with asthma and allergy to dogs. Air cleaners will be installed in the bedrooms and living rooms in the homes of children and adolescents aged 8-17 years at the study entry, with allergy to dogs, but not to house dust mites. The investigators will look upon the significance of this study, and of a previous study with a similar design and the same main parameters to find out if this trial supports the results of the first trial by the same project leader, or makes it likely that the seemingly beneficial effects of the first study occurred by chance. Main parameters: hyperventilation cold air challenge test Supportive parameters: serum ECP symptom scores The trial will be a parallel, double blind placebo controlled one.

The trial is performed to assess efficacy and safety of the Allergopharma house dust mite allergoid in bronchial asthma.

The trial is performed to assess efficacy and safety of a purified standardised bee venom preparation in bee venom allergy

The primary objective is to demonstrate the non-inferiority of ciclesonide compared to beclomethasone-HFA in the occurrence of Class 1 lens event for nuclear (NO), cortical (C), or posterior subcapsular (P) lens opacification within 12 months. Secondary objectives are to compare ciclesonide and beclomethasone with respect to class II and class III best corrected visual acuity and intraocular pressure from baseline to 12 months.

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).
