Active clinical trials for "Rhinitis"

Allergy is a public health problem as more than 20% of western society is affected by it. Symptomatic treatment of allergy suffices with less severe allergy. Patients with more severe allergy should be treated with allergen immunotherapy (AIT). Present options of AIT are efficient but of long duration, associated with side effects and require much time from the patient. With Intralymphatic immunotherapy (ILIT), allergen is injected into the lymph node under ultrasound guidance. ILIT is complete after 3 treatment visits, may be more effective than and may have markedly fewer side effects than presently available methods of AIT. The investigators plan a randomized, parallel group, open-label, prospective case-control study to assess immunological changes in lymph node and peripheral blood after intralymphatic (ILIT) or subcutaneous (SCIT) immunotherapy with POLVAC. The intervention consists of one ultrasound-guided injection of allergen into inguinal lymph node or subcutaneous injection 1 cm next to the lymph node. Intervention quality (accuracy of injection) will be assessed by the administering physician during treatment and via video recording on the ultrasound device. Side effects associated with treatment will be recorded by the patients for 3 days after the injection. The effect of intralymphatic or subcutaneous injection on lymph node tissue and immunoglobulins E and G4 in serum as well as cellular analyses of lymph node tissue and peripheral blood will be determined in samples taken during the trial. The primary effect parameter is the effect of a single intralymphatic allergen injection on immunological parameters as well as allergen delivery to the lymph node as compared with a single subcutaneous injection.

The primary objective of this 5-year study is to demonstrate non-inferiority of children compared to adults by exploring long-term effectiveness after treatment with TA Bäume (trees) and TA Gräser (grass) following a perennial posology.

Most asthma is allergic in origin. The purpose of this study is to better understand the airway immune response to inhaled allergens in order to identify factors that promote asthma.

Birch pollen allergic patients are currently treated by subcutaneous injections of pollen extracts either by standard allergen specific immunotherapy (SIT) or ultra-rush immunotherapy. Such treatment is prone to side effects and has to be performed in a hospital environment due to the risk of potential anaphylactic reactions. The aim of this study is to test the new product AllerT expected to show widely reduced side effects. AllerT will be injected via two different routes, subcutaneous versus intradermal. The primary endpoint of the study is the local and systemic safety of repeated injections of the product. Since AllerT should provide patients with a pre-seasonal treatment to decrease seasonal allergic symptoms, we will also evaluate the potential efficacy of the approach using a nasal provocation test (NPT) with birch pollen

Empty Nose Syndrome patients suffer from disabling physical symptoms and considerable distress. To date there is no definitive cure for these symptoms. Established treatment modalities include saline irrigation, surgical implantation of materials or simply use of cotton wads/ silicon cones to simulate the resistive action to airflow of the resected turbinates. This study will research the effectiveness of a new treatment modality in the treatment of Empty Nose Syndrome. This novel treatment method involves the use of botulinum toxin type A (Botox).

This study will test the effectiveness of an investigational treatment for patients with ragweed-induced asthma, sometimes called fall seasonal asthma. The treatment being tested is a series of anti-ragweed shots. The purpose of the study is to determine whether a short series of injections with Amb a 1-immunostimulatory oligodeoxyribonucleotide conjugate (AIC) can cause a long-lasting reduction in the symptoms of asthma that are caused by fall hay fever allergies.

Tree MATAMPL has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to Tree (birch, alder, hazel) 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 Efficacy will be assessed by exposing allergic subjects to birch pollen in an environmental exposure chamber EEC. Patient symptomatic response to birch pollen and patient quality of life in the EEC will be determined.

Some people with nasal allergy symptoms continue to have symptoms even after treatment with a nasal steroid spray. The purpose of this study is to see if these patients are helped by adding another medication (montelukast) to their treatment compared to placebo (a substance that looks like the active medication but does not contain the drug).

The primary objective of the study is to determine the efficacy of REGN1908-1909, as compared to placebo, to reduce allergic rhinitis/conjunctivitis symptoms and allergy rescue medication use during natural cat exposure. The Secondary Objectives are: To assess the reduction of allergic symptoms and use of allergy rescue medications after treatment with REGN1908-1909 versus placebo, as measured by the individual components of the CSMS To assess health-related quality of life (HRQoL) as measured by the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ[S]) To determine the efficacy of REGN1908-1909, as compared to placebo, to inhibit a wheal-and-flare response to a skin prick test with cat allergen To assess the durability of effect in allergic rhinitis and conjunctivitis symptom and medication scores after multiple doses of REGN1908-1909 compared to placebo given every 12 weeks (Q12W) To determine the efficacy following multiple doses of REGN1908-1909 compared to placebo at inhibiting a wheal-and-flare response to a skin prick test with cat allergen To estimate the effect of REGN1908-1909 on lung function, as compared to placebo, in patients with asthma To determine the efficacy of REGN1908-1909 as compared to placebo to reduce asthma symptoms in patients with asthma To assess whether there is a difference in asthma rescue medication use in patients with asthma who are treated with REGN1908-1909 compared to placebo To assess whether there is a difference in nighttime awakenings in patients with asthma treated with REGN1908-1909 compared to placebo To evaluate the short-term and long-term safety and tolerability of REGN1908-1909, including the incidence of hypersensitivity reactions, local injection site reactions, and asthma exacerbations To determine systemic exposure of total (free and antigen-bound) antibodies as measured by concentration of REGN1908 and REGN1909 To assess the immunogenicity of REGN1908 and REGN1909

A safety study conducted on subjects ≥16 years old evaluating the safety of 4 intralymphatic injections of 2 different dose levels of the investigational short and tall ragweed product. Biomarkers will be assessed at baseline and at multiple time points post-treatment.
