Follow-up Study to Investigate the Effect of GSK2245035 on Nasal Allergic Reactivity in Subjects Completing Treatment in Study TL7116958
March 8, 2018 updated by: GlaxoSmithKline
A Single-centre, Follow-up Study to Investigate the Effect of GSK2245035 on Nasal Allergic Reactivity in Subjects Who Completed Treatment in Study TL7116958 in 2014
This study will evaluate the duration of effect of GSK2245035 on allergic reactivity by repeating a nasal allergen challenge (NAC) approximately one year after treatment in subjects from TL7116958.
This is a single centre, single period study in subjects with respiratory allergy/allergies who completed the study TL7116958 in 2014 to investigate the long term effect of previous treatment with GSK2245035 compared with placebo on total nasal symptoms elicited by nasal allergen challenge.
Subjects and staff will remain blinded to the treatment received in the TL7116958 study (GSK2245035 or placebo).
The study will consist of a screening visit to assess eligibility criteria, a study period consisting of a single visit when the nasal allergen challenge will be performed, and follow up by phone or a clinic visit at the discretion of the investigator 4-7 days following the allergen challenge.
Eligible subjects will participate in this study for approximately70 days total from screening to follow up.

Other: Nasal allergen challenge
Subjects do not receive study medication in this study 204509.
Subjects who carried from study TL7116958 treatment group GSK2245035 will undergo NAC with pollen allergen extract.
|
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.

Measure Description |
Time Frame |
---|---|---|
Mean Change From Baseline in the Total Nasal Sym. Score (TNSS) at Post-NAC 15 Minutes (Min)
Time Frame: Day 1 (Baseline [pre-NAC] and post-NAC 15 min)
|
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).
