Filter by:GSK2245035 is a highly selective Toll-like Receptor 7(TLR7) agonist capable of preferentially inducing the production of interferon alpha (IFNα) versus tumor necrosis factor alpha (TNFα). The aim of this FTIH study is to collect tolerability, pharmacokinetic (PK) and pharmacodynamic (PD) information to enable the identification of appropriate safe doses of intranasal (i.n) GSK2245035, associated with up-regulation of TLR7-mediated genes in the nasal milieu, for use in subsequent clinical drug development studies. There will be two parts to the study: Healthy Volunteers will be dosed in escalating single doses in Part 1, followed by Allergic Rhinitis (AR) subjects dosed similarly in Part 2.
The purpose of this study is to determine whether specific subcutaneous immunotherapy affects fractions of regulatory T lymphocytes and histamine H2 receptor expression and ZAP70 in regulatory T lymphocytes.
The purpose of this study is to determine the onset of action of two commercially available over-the-counter antihistamines (Loratadine and Fexofenadine) in a model of seasonal allergic rhinitis (SAR). Participants undergo sensitization exposures to Mountain Cedar (juniperus ashei) pollen in a Biogenics Research Chamber; those who demonstrate an adequate allergic response determined by the Major Symptom Complex (MSC) score will then receive drug.
This is a 2-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, efficacy and safety study of ciclesonide nasal aerosol administered once daily to male and premenarchal female subjects 6 to 11 years-old diagnosed with SAR.
More than 70% of birch pollen allergic patients suffer from allergic reactions to certain foods, e.g. stone fruits, hazelnut and some vegetables. However, specific immunotherapy (SIT) with birch pollen extract is not effective for the treatment of associated food allergy in a substantial number of patients. Based on our previous clinical and immunological investigations of birch pollen related food allergy (BPRFA) the investigators hypothesize that for effective SIT of this abundant food allergy the disease-eliciting food allergens should be employed. To prove this concept, the investigators aim to sublingually administer the major apple allergen, Mal d 1, to birch pollen-allergic patients with concomitant apple allergy and evaluate clinical and immunological effects of this treatment. The investigators choose Mal d 1 as model food allergen because (i) its cross-reactivity with Bet v 1 has been well characterized,(ii) apple is the most frequent trigger for BPRFA and (iii) recombinant(r)Mal d 1 was well tolerated after sublingual administration to 20 birch pollen-allergic patients in a previous study. Sublingual administration of a defined concentration of GMP-rMal d 1 will be compared with equal doses of GMP-rBet v 1 as a positive control and placebo-treatment. Clinical parameters will include skin prick tests (SPT) and objective and subjective assessment of apple and birch pollen-induced allergic symptoms. Immunological parameters will comprise the analysis of antibody and T cell responses to Mal d 1 and Bet v 1 as well as the evaluation of basophil activation. The proposed pilot study will be a first investigation of the concept to specifically treat BPRFA with the involved food allergens and thus, represents an important step in the development of an efficient and safe therapy in the future.
The study will evaluate the dose response of immunotherapy against grass pollen allergy using the recombinant grass pollen vaccine BM32. Efficacy will be analyzed by: - skin prick testing - grass pollen inhalation challenge - antibody responses. In addition, the safety of subcutaneous application of BM32 will be evaluated.
This study will compare the nasal congestion symptom relief of phenylephrine extended release tablets and placebo in participants with allergic rhinitis.
The objective of the study was to determine the efficacy and tolerability of 20 mg of Bilastine, compared to Desloratadine and placebo for the treatment of Seasonal Allergic Rhinitis.
The Purpose of this study is to evaluate the safety and efficacy of MP03-36 (0.15% azelastine hydrochloride)at dosages of 2 sprays per nostril once daily and 2 sprays per nostril twice daily in patients with seasonal allergic rhinitis.
The aim of the study is to identify changes in potential biomarkers after peptide immunotherapy for that may subsequently be developed as biomarkers that correlate with clinical efficacy.
