TNSS was obtained from 4 individual nasal sym. including nasal congestion, rhinorrhoea, nasal itch and sneezing. Participants rated sym. on a 4-point scale. For nasal blockage and congestion the scores were (0= Breathing through nose freely and easily, 1= Slight difficulty breathing through nose, 2= Moderate difficulty breathing through nose and 3= Severe difficulty breathing through nose). For rhinorrhoea, nasal itching and sneezing (0= None: No sym. whatsoever; Absent, 1= Mild: Sym. is present, noticeable but not bothersome, 2= Moderate: Sym. is bothersome, but tolerable and 3= Severe: Sym. which are bothersome, harder to tolerate). The individual sym. scores were combined to produce a TNSS. TNSS were reported as median (credible interval). The baseline values were the latest pre-dose assessments. Change from baseline was measured as the value recorded at 15 min post-NAC minus Baseline value.

TNSS was obtained from 4 individual nasal sym.: nasal congestion, rhinorrhoea, nasal itch and sneezing. Par rated sym. on a 4-point scale. For nasal blockage and congestion the scores were (0= Breathing through nose freely and easily, 1= Slight difficulty breathing through nose, 2= Moderate difficulty breathing through nose and 3= Severe difficulty breathing through nose). For rhinorrhoea, nasal itching and sneezing (0= None: No sym. whatsoever; Absent, 1= Mild: Sym. is present, noticeable but not bothersome, 2= Moderate: Sym. is bothersome, but tolerable and 3= Severe: Sym. which are bothersome, harder to tolerate). The individual sym. scores were combined to produce a TNSS. TNSS were reported as median (credible interval). BL values were the latest pre-dose assessments. Change from BL was measured as the value recorded at a specified time point minus BL value. The max change from BL from the set of individual PNIF % reduction measurements made over the 0 to 6 h sampling period.
PNIF data recorded at Baseline pre-challenge and at 15, 30 min and 1h. The percent change from Baseline and at specified time point was derived by the formula (PNIF at Baseline minus PNIF at Post-NAC specified time point) divided by PNIF at Baseline) multiplied by 100. The baseline values were the latest pre-dose assessments. The baseline value were the latest pre-dose assessments. Percent change in PNIF were reported as median (credible interval). WM 0-1 h of 15, 30 min and 1 h was reported. WM were derived by first calculating the AUC using the trapezoidal rule, and then dividing by the time interval. If available, actual times were used in the calculation, otherwise planned relative times were used for the calculation.

| Pollen allergen extract | OTHER | Pollen (tree, grass or ragweed) allergen extracts will be provided by the research unit and diluted as required in normal saline. The specific pollen allergen extract that will be used for the nasal allergen challenge will be selected according to each subject's individual allergic sensitivity demonstrated in the previous study, TL7116958. If possible, extracts remaining from this study in 2014 will be used, provided they have not reached their expiry date. |
Inclusion Criteria: * Adult subjects with allergic rhinitis who completed study TL7116958 in 2014. * Healthy as determined by the investigator or medically qualified designee based on a brief physical examination. * Males and non-pregnant females. * Capable of giving signed informed consent which i...
Pollen allergen extract is being studied for use in asthma and rhinitis. It is an investigational therapy in clinical development, and it is not approved for any use. The drug is being evaluated in a respiratory therapeutic area context, with a completed Phase 2 trial involving 16 participants in Canada.
Pollen allergen extract is being developed by GSK plc, a pharmaceutical company traded on the stock exchange under the ticker GSK. The company is conducting clinical research on this investigational drug for respiratory conditions, specifically asthma and rhinitis.
Pollen allergen extract is in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. A Phase 2 trial has been completed, but the drug remains under study and is not yet available as a treatment.
Pollen allergen extract has one completed clinical trial, identified as NCT02446613. This Phase 2 study, titled 'Follow-up Study to Investigate the Effect of GSK2245035 on Nasal Allergic Reactivity in Subjects Completing Treatment in Study TL7116958,' enrolled 16 participants with asthma and rhinitis in Canada.
Yes, Pollen allergen extract is also known as GSK2245035. The clinical trial NCT02446613 references GSK2245035 in its title, indicating that this is the same investigational drug. This alternative name may be used in scientific literature and trial registries.
