FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Participants were exposed to bronchial allergen challenge (BAC) at the one-week follow-up visit (one week after the eighth dose of the study treatment). Minimum FEV1 over 4-10 hours post-allergen challenge (minimum LAR) is the minimum value of all of the post-saline time points between 4 and 10 hours post-allergen challenge, inclusive of the 4 and 10 hours timepoints. Absolute change from saline in minimum FEV1 was calculated as the minimum FEV1 minus the saline FEV1 value. Per-Protocol Population comprises of all randomized participants who received at least one dose of study treatment and commence a BAC at follow-up and comply with the protocol.
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Participants were exposed to BAC at the one-week follow-up visit (one week after the eighth dose of the study treatment). Weighted mean FEV1 over 4-10 hours post-allergen challenge includes all post-saline time points between 4 and 10 hours post-allergen challenge, inclusive of the 4 and 10 hours timepoints. The weighted mean FEV1 was derived by calculating the area under the curve, and dividing the value by the relevant time interval. Absolute change from saline at each time point was calculated as the highest allergen challenge FEV1 value minus the highest saline FEV1 value.
The measurement of body temperature with an automatic thermometer placed in the subject's mouth will be performed by the research unit staff when a subject is in the unit and by the individual when a subject is not in the unit
Spirometry will be performed at screening and Peak Expiratory Flow will be measured at all other planned time points
Hematology, clinical chemistry, urinalysis and additional parameters to be tested
Visual examination of the nose will be done to assess the color of mucosa, degree of turbinate swelling, presence/description of any secretion, presence/absence of infection, post-nasal drip, crusting, signs of bleeding and any other signs of irritancy
Nasal tolerability will be assessed using a Visual analogue scale scoring system. Subjects will be asked to respond to various statements of a questionnaire by placing a small vertical mark on a horizontal line, 10 centimeters in length, with a statement placed at each end of the line. Nasal symptoms of rhinorrhea, blockage, itchiness, soreness or dryness and modification of the sense of taste/smell will be assessed
Blood samples will be collected to measure levels of TLR7-induced soluble biomarkers and/or allergic blood biomarkers, including but not limited to immunoglobulins
During allergen challenge visits, nasal lavage samples will be collected from one nostril only; nasal filters will be inserted in the other nostril and will remain there for 5 minutes
An AE is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
The hematology parameters included are platelet count, red blood cell (RBC) count, white blood cell (WBC) count, reticulocyte count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), neutrophils, lymphocytes, monocytes, eosinophils, basophils.
Clinical chemistry parameters included are blood urea nitrogen (BUN), creatinine, glucose, potassium, C-Reactive protein (CRP) potassium, chloride, total carbon dioxide, calcium, total and direct bilirubin, Aspartate transaminase (AST), Alanine transaminase (ALT), alkaline phosphatase, uric acid, protein and albumin
Urinalysis parameters included are specific gravity, potential of hydrogen (pH), glucose, protein, blood and ketones by dipstick, microscopic examination (if blood or protein is abnormal)
A 12 lead electrocardiogram (ECG) will be measured using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals.
Visual nasal examination will be conducted by a trained physician
Nasal tolerability symptoms itching, discomfort, post-nasal drip, rhinorrhoea, obstruction will be assessed using a Visual analogue score system

GSK2245035 is an investigational small molecule being developed for respiratory conditions including mild asthma, allergic rhinitis, and asthma with rhinitis. It is administered intranasally and is being studied for its effects on allergic reactivity and allergen-induced asthmatic responses.
GSK2245035 is a Toll-like receptor 7 (TLR7) agonist. It targets TLR7, a receptor involved in immune responses, and is being investigated for its potential to modulate allergic airway responses in conditions like asthma and allergic rhinitis.
GSK2245035 is developed by GSK plc, a global pharmaceutical company traded on the London Stock Exchange under the ticker GSK. The company is conducting clinical trials to evaluate the drug's safety and efficacy in respiratory allergy and asthma indications.
GSK2245035 is in Phase 2 clinical development. It is an investigational drug, not yet approved by regulatory authorities. All three completed trials were Phase 2 studies, and the drug remains under investigation for respiratory allergic conditions.
GSK2245035 has completed three Phase 2 trials: NCT01607372, NCT01788813, and NCT02833974. These studies evaluated the drug in subjects with respiratory allergies, mild asthma with allergic rhinitis, and asthma, across Canada, Germany, and the United Kingdom.
Yes, GSK2245035 is a TLR7 agonist, meaning it activates Toll-like receptor 7. This mechanism is central to its investigational use in modulating immune responses in allergic airway diseases like asthma and rhinitis.
