17 Clinical Trials for Various Conditions
The PQGrass306 (G306) clinical trial is the pivotal Phase III efficacy clinical trial of PQ Grass. The aim of the G306 pivotal clinical trial is to confirm the efficacy and safety of the optimal effective dose of PQ Grass 27600 SU. This will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak grass pollen season (GPS).
The objective of this study is to evaluate ocular and nasal signs and symptoms in patients with seasonal allergic rhinoconjunctivitis following allergen exposure in the Allergen BioCube.
The purpose of the study is to assess the efficacy and safety of 300 IR sublingual tablet of grass pollen allergen extract compared to placebo in adult patient with allergic rhinoconjunctivitis.
The purpose of this study is to compare the treatment effect of three treatment regimens of HDM-SPIRE vs placebo and to evaluates the treatment effect of HDM-SPIRE on symptoms, rescue medication usage, Quality of Life and Sleep Quality
The purpose of this study is to compare the treatment effect of two treatment regimens of Cat-PAD vs placebo and to evaluates the treatment effect of Cat-PAD on symptoms, rescue medication usage and Quality of Life.
This is a continuing research study of a vaccine for allergy to Japanese Red Cedar. The vaccine is called CryJ2-DNA-LAMP Plasmid vaccine. This research study will determine how the vaccine is tolerated and how previous Phase IA research participants respond to the vaccine in a booster dose. CryJ2-DNA-LAMP Plasmid vaccine is investigational, which means it is not approved for use by the United States Food and Drug Administration (FDA) but is available in research studies like this one. The study is a Phase IB, prospective, three cohort, open label study conducted on one cohorts of non-atopic subjects and two cohorts of subjects with a history of allergic rhinitis symptoms to Japanese red cedar CryJ 2 pollen allergen that participated in the previous Phase IA study (all the subjects participated in the previous study). The study will be conducted at 1 study center. Subjects are enrolled in the trial for a period of 80 days. The objectives of the statistical analyses are to establish the safety and to explore the immunogenicity of the LAMP-vax vaccine. All statistical analyses conducted on the data from this trial will be exploratory in nature. The primary objective of this Phase IB Study is to evaluate the safety and immunological responses of an additional dose of CryJ2-DNA-LAMP plasmid vaccine delivered intramuscularly (IM) to subjects who previously received 4 doses of CryJ2-DNA-LAMP vaccine delivered IM every 2 weeks in the previous Phase IA study.
This is a research study of a vaccine for allergy to Japanese Red Cedar. The vaccine is called CryJ2-DNA-LAMP Plasmid vaccine. This research study will determine how the vaccine is tolerated and how research participants respond to the vaccine in various doses. CryJ2-DNA-LAMP Plasmid vaccine is investigational, which means it is not approved for use by the United States Food and Drug Administration (FDA) but is available in research studies like this one. This is the first time that CryJ2-DNA-LAMP Plasmid vaccine is being given to humans. The purpose of this study is to evaluate the safety of an investigational vaccine intended to treat allergy to Japanese red cedar. The vaccine is composed of DNA, which is the material that cells use to provide instructions to make proteins. The DNA carries the information necessary to make a special protein which is a combination of a protein found in all cells, LAMP (lysosomal associated membrane protein), and the protein from Japanese red cedar that causes the allergy known as Cry J2. This vaccine is intended to help re-educate the immune system with respect to how it will respond to naturally occurring red cedar allergen and eliminate the allergic symptoms. Another purpose of this study will be to document the immune response to the vaccine Subjects that are eligible to participate in this study will be assigned by whether they are sensitive or non sensitive to CryJ2 or Mountain Cedar and chance (like flipping a coin) to one of 3 study vaccine groups: Group 1: will receive four (4) 4-milligram doses of the study vaccine. Group 2: will receive four (4) 2-milligram doses of the study vaccine. Group 3: will receive four (4) 4-milligram doses of the study vaccine. The study vaccine is administered as an intramuscular injection. Enrolled subjects will receive the study vaccine every 14 days (at day 0, 14, 28 and 42). Subjects will know their study vaccine assignment. Participants who are not allergic to Japanese red cedar will be assigned to Group 1. Participants who do have an allergy to Japanese red cedar or Mountain Cedar will have an equal chance of being assigned to Group 2 or 3. There will be between 18 to 30 men and women participating in the study at one location. Your participation in this study will last approximately 72 days.
To evaluate the effect of Conjunctival Allergen Challenge (CAC) with Dust Mites on nasal and ocular allergic symptoms following allergen exposure in the Allergen BioCube (ABC).
Grass pollen allergens are universally recognised as a major cause of allergic diseases in humans, including asthma, allergic rhinitis, conjunctivitis and dermatitis. The purpose of the current study is to evaluate allergy symptoms and allergy medication in subjects with grass-related rhinoconjunctivitis.
To study the impact of alcaftadine in patients treated with other opthalmic ocular agents (or specific topical opthalmic treatment) in an allergy subspecialist outpatient setting.
This is a Phase 2a study to evaluate the efficacy and safety of Norketotifen (NKT) in subjects with allergic rhinitis.
TX-SMILE is an investigator-initiated, multi-center, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy, safety, and tolerability of intra-lymphatic administration of an approved allergenic extract for the immunotherapy treatment of allergic rhinitis and conjunctivitis due to pollen from the conifer Mountain Cedar.
An objective of this study is to standardize temperature values derived from thermograms of the facial region. It is anticipated that the mean temperature of a defined region of interest, such as the eyes, nose, or sinuses, might be useful for future applications. The investigators will attempt to determine normal temperature ranges based on participants' age and gender.
Evaluate the relative efficacy of four dosing regimens of bilastine tablets (given either once or twice per day) versus placebo in patients with Seasonal Allergic Rhinitis (SAR) in the Mountain Cedar season in south Texas and Oklahoma based on the mean change from baseline in Reflective Total Nasal Symptom Scores (TNSS) assessed over 14 days of treatment.
PQGrass309 is aimed at exploring the expected average treatment effect of PQ Grass 27600 SU cumulative dose on symptom and medication score in a field setting. The study will enrol adult subjects with seasonal allergic rhinitis and/or rhinoconjunctivitis (SAR) induced by grass pollen exposure.
To compare the clinical efficacy of olopatadine and fluticasone in a 3-week single center, double-masked, randomized, placebo controlled parallel treatment conjunctival allergen challenge (CAC) study in patients with allergic conjunctivitis
The purpose of this study is to see whether rEV131 when given as a nasal spray in a single dose to each nostril is safe and can reduce the signs and symptoms of allergic rhinitis (hay fever) caused by an allergen challenge. All patients enrolled will be known to be allergic to ragweed pollen and will be given ragweed pollen extract in both nostrils 30 minutes after either rEV131 or innactive vehicle (placebo). The signs and symptoms (sneezing, itching, stuffiness and runny nose) will each be given a score from 0 to 3 by the patient and these will be added together and the combined scores from patients treated with rEV131 will be compared with those who received placebo.
