BACKGROUND Peptide therapy targets T cells directly with short peptides containing multiple T-cell receptor epitopes. Murine studies suggest T-cell anergy as the mechanism of action; however, changes in T-cell cytokine profiles may be more relevant in human beings. OBJECTIVE We sought to study the effects of peptide therapy on ex vivo antigen-specific(More)
We induced in allergic humans the counterpart of murine experimental T-cell tolerance. T-cell lines from cat-allergic humans were used to map T-cell epitopes for the principal allergen of cat dander, Fel d 1. Two peptides of 27 amino acids each were synthesized to contain the dominant epitopes (ALLERVAX CAT). After a safety trial, we carried out a blinded(More)
BACKGROUND Cells producing a T(H2)-cytokine profile play an important role in the onset and maintenance of atopic diseases, and therefore specific immunotherapy is aimed to induce a switch to cells producing a T(H1)- or T(H0)-cytokine profile. Recently, a novel form of immunotherapy making use of synthetic peptides from the major cat allergen Fel d 1 has(More)
OBJECTIVE This study explored the safety and efficacy of cetirizine for treatment of allergic rhinitis and asthma. METHODS Daily treatment for 6 weeks with cetirizine 10 mg (93 patients) was compared with placebo treatment (93 patients) in a randomized, double-blind parallel study of patients with allergic rhinitis and asthma. This multicenter study was(More)
BACKGROUND Many potential users of the H1 antihistamine cetirizine are asthmatic and may be using inhaled albuterol. This study was conducted to assess the possible bronchodilatory effect of cetirizine in patients with mild-to-moderate asthma and to determine whether cetirizine interacts with albuterol. METHODS In a randomized, double-blind,(More)
Peptides have been designed to be T cell tolerogenic for the principal allergens of the cat. These have been administered in several dosage programs to cat-sensitive patients in multicenter blinded studies. In contrast to proteins in standard extracts, IgE sensitization to peptides is an uncommon event. Pretreatment prick tests with peptides will identify(More)
More than 2,000 patients have been dosed in the clinical development programs for Allervax Cat and Ragweed products in North America, Europe and Japan. Two peptides derived from Fel d 1 and three peptides derived from Amb a 1 were selected for clinical development following T cell epitope mapping of these major allergens. Clinical activity has been(More)
The purpose of this study was to compare the efficacy and safety of cetirizine, 10 mg, once daily in the morning to terfenadine, 60 mg, BID in the treatment of seasonal allergic rhinitis. The multicenter, single-blind, parallel study involved 160 patients, who were all included in the safety and efficacy analysis. The results of the study showed that both(More)
