Trial Outcomes & Findings for Phase II HDM-SPIRE Safety and Efficacy Study (NCT NCT02150343)

NCT ID: NCT02150343

Last Updated: 2018-06-15

Results Overview

The primary endpoint was mean Combined Score (CS) over a 3 week period (50-52 weeks after randomisation) in the HDM-SPIRE treatment groups compared with the mean CS in the placebo group. A higher score indicated more severe symptoms or greater use of allergy rescue medication and thus a low score indicated a better outcome. CS = Total Rhinoconjunctivitis Symptom Score (TRSS) + Rescue Medication Score (RMS). Eight symptoms are defined in the TRSS, 4 nasal symptoms: runny nose, sneezing, blocked nose and itchy nose and 4 non-nasal symptoms: itchy eyes; watery eyes; red eyes, and sore eyes. Each symptom was rated in severity on a score of 0-3 (0=absent, 3=severe); TRSS was divided by the number of symptoms (8) to provide an average score per symptom of 0-3. The RMS score ranged from 0 (no allergy rescue medication use per day) to 3 (at least one dose of systemic corticosteroid per day). The RMS score was not additive, and therefore the maximum RMS was 3 and the maximum CS was 6.

Participant Flow

715 participants were randomised on to the study through the IRT. However, one participant was inadvertently randomised before eligibility had been confirmed by the PI, and was withdrawn due to a finding of inspiration/expiration wheeze before receiving any study medication. Therefore results refer to 714 participants throughout.

Timeframe: Weeks 50 to 52 after randomisation

The RQLQ (Rhinoconjunctivitis Quality of Life Questionnaire) was completed by subjects at the end of the study (50-52 weeks after randomisation). RQLQ is a validated method of assessing quality of life and has 28 questions in seven domains (activity limitation, sleep problems, nasal symptoms, eye symptoms, non-nasal/eye symptoms, practical problems and emotional function). Subjects recalled how their rhinoconjunctivitis had been during the last week and responded to each question on a seven-point scale (0 = no impairment, 6 = maximum impairment). Questions were equally weighted, and the RQLQ score was the mean of the 28 questions and could range from zero to six. A higher score indicated greater impact on quality of life and thus a low score indicated a better outcome.

Timeframe: Weeks 50 to 52 after randomisation

Population: The overall number of participants analysed represents the number of subjects that completed the assessment, not all subjects that completed the study (651) completed the Clinical Global Impression of Change (633).

A Global Impression of Change in Rhinoconjunctivitis Symptoms assessment was completed by subjects at the final follow-up visit. Subjects rated their overall allergy symptoms at the end of the study relative to baseline on a seven-point scale as follows:0. very much better; 1. moderately better; 2. a little better; 3. unchanged; 4. a little worse; 5. moderately worse; 6. very much worse. For reporting the individual categories were grouped as follows: moderately or very much better; any improvement; no change and any worsening. Subjects could therefore be reported in more than group and the total number reported does not match the overall number of participants analysed.

SECONDARY outcome

Timeframe: Weeks 50 to 52 after randomisation

Mean Total Rhinoconjunctivitis Symptom Score (TRSS) in HDM-SPIRE treatment groups compared with placebo. Eight symptoms are defined in the TRSS, 4 nasal symptoms: runny nose, sneezing; blocked nose, and itchy nose and 4 non-nasal symptoms: itchy eyes; watery eyes; red eyes, and sore eyes. Each symptom was rated in severity on a score of 0-3 (0. absent; 1. mild, barely noticeable; 2. moderate, annoying/troublesome; 3. severe, very annoying/very troublesome), therefore TRSS could range from 0 to 24. Higher TRSS reflected more severe symptom scores. Symptoms were scored daily for a period of approximately 3 weeks, 50-52 weeks after randomisation.

Mean daily Total Non-nasal Symptom Score (TNNSS) in HDM-SPIRE treatment groups compared to placebo. TNNSS was the sum of all the non-nasal symptom scores (itchy eyes; watery eyes; red eyes; sore eyes) and could range from 0 to 12. Higher TNNSS reflected more severe symptoms. Subjects rated the severity of each symptom over the last 24 hours as follows: 0. absent; 1. mild, barely noticeable; 2. moderate, annoying/troublesome; 3. severe, very annoying/very troublesome. Symptoms were scored daily for a period of approximately 3 weeks, 50-52 weeks after randomisation.

Mean RMS (Rescue medication score) in HDM-SPIRE treatment groups compared with placebo groups. The use of rhinoconjunctivitis rescue medications was recorded by the subject on a daily basis just before bedtime for approximately 21 days, 50-52 weeks after randomisation and was scored based on a previously published system as follows: 0 = no allergy rescue medication used per day; 0.5 = at least one dose of antihistamine eye drops used per day; 1 = at least one dose of oral antihistamine used per day; 2 = at least one dose of intranasal corticosteroid used per day; 3 = at least one dose of systemic corticosteroid used per day. The score was according to the highest level of rescue medication used and was not additive.
