About this study

Official title: 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change From Baseline in the Total Nasal Sym. Score (TNSS) at Post-NAC 15 Minutes (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). 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.

    Measured: Day 1 (Baseline [pre-NAC] and post-NAC 15 min)

  2. Mean Change From Baseline in the TNSS Over Post-NAC 1 h

    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 a specified time point minus Baseline value. Weighted mean (WM) 0-1h of 15, 30 min and 1 h was reported.

    Measured: Day 1 (Baseline [pre-NAC], 15 to post-NAC 1h)

  3. Mean Change From Baseline in the TNSS Over Post-NAC 6 h

    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 value recorded at a specified time point minus Baseline value. WM 0-6 h of 15, 30 min, 1, 2, 3, 4, 5, 6h was reported.

    Measured: Day 1 (Baseline [pre-NAC] to post-NAC 6 h)

  4. Maximum (Max) Mean Change From Baseline (BL) in the TNSS Over Post-NAC 6 h

    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.

    Measured: Day 1 (Baseline [pre-NAC] to post-NAC 6 h)

  5. Percent Change From Baseline in the Peak Nasal Inspiratory Flow (PNIF) at Post-NAC 15 Min

    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.

    Measured: Day 1 (Baseline [pre-NAC] and post-NAC 15 min)

  6. Percent Change From Baseline in the PNIF Over Post-NAC 1 h

    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. 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.

    Measured: Day 1 (Baseline [pre-NAC] to post-NAC 1 h)

  7. Percent Change From Baseline in the PNIF up to Post-NAC 6 h

    PNIF data recorded at Baseline pre-challenge and at 15, 30 min, 1, 2, 3, 4, 5, 6h. 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. Percent change in PNIF were reported as median (credible interval). WM 0-6h of 15, 30 min, 1, 2, 3, 4, 5, 6h 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.

    Measured: Day 1 (Baseline [pre-NAC] to post-NAC 6 h)

  8. Maximum Percent Change From Baseline in PINF Over Post-NAC 6 h

    PNIF data recorded at Baseline pre-challenge and at 15, 30 min, 1, 2, 3, 4, 5, 6h.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2018.
