Efficacy of 2LALERG (Homeopathic Drug) in Allergic Rhinitis Related to Grass Pollen (LLB-2016-01)
Randomized, Double-blind, Placebo-controlled Study to Measure 2L®ALERG (Homeopathic Drug) Efficacy on Symptoms of Allergic Rhinitis and Allergic Rhinoconjunctivitis in Patients With a Seasonal Allergy to Grass Pollen
The primary objective of this study is to demonstrate the superiority of 2L®ALERG over placebo in terms of efficacy on the symptoms of allergic rhinitis and allergic rhinoconjunctivitis in patients with seasonal allergy to grass pollen, corrected according to rescue medication intake. The secondary objectives are to compare the allergy symptoms, the rescue medication intake, the quality of life and the safety in patients treated with 2L®ALERG or with a placebo.
This is a multicentre, randomized, double-blind, two-parallel group, interventional placebo-controlled study with a notified homeopathic medication, marketed since 2002.
Fifty patients will be recruited per group to achieve 40 cases completed per group, i.e., a total of 100 patients included for 80 cases completed.
Screening will be done before the peak of pollination and the treatment will be set up two months before traditional pollen peak, then visits at 3 months and 6 months, or end of the peak.
The treatment will consist of 1 capsule daily, fasting morning, following the numerical order of 1 to 10 capsules for 6 months.
The placebo will have the same form, colour, taste and aspect. The allowed concomitant treatments are the already established treatments for associated pathologies not liable to have an impact on the proper conduct of the study and the rescue medications allowed in the first-line adjuvant treatment (oral or topical antihistamines [nasal or eye] and eye cromoglycate, topical nasal corticosteroids [in case of failure or insufficiency of those above]).
The prohibited treatments are the oral or injectable corticosteroids and the anti-leukotrienes.
Study Overview
Detailed Description
The primary objective of this study is to demonstrate the superiority of 2L®ALERG over placebo in terms of efficacy on the symptoms of allergic rhinitis and allergic rhinoconjunctivitis in patients with seasonal allergy to grass pollen, corrected according to rescue medication intake. The secondary objectives are to compare the allergy symptoms, the rescue medication intake, the quality of life and the safety in patients treated with 2L®ALERG or with a placebo.
This is a multicentre, randomized, double-blind, two-parallel group, interventional placebo-controlled study with a notified homeopathic medication, marketed since 2002.
Fifty patients will be recruited per group to achieve 40 cases completed per group, i.e., a total of 100 patients included for 80 cases completed.
Screening will be done before the peak of pollination and the treatment will be set up two months before traditional pollen peak, then visits at 3 months and 6 months, or end of the peak.
The treatment will consist of 1 capsule daily, fasting morning, following the numerical order of 1 to 10 capsules for 6 months.
The placebo will have the same form, colour, taste and aspect. The allowed concomitant treatments are the already established treatments for associated pathologies not liable to have an impact on the proper conduct of the study and the rescue medications allowed in the first-line adjuvant treatment (oral or topical antihistamines [nasal or eye] and eye cromoglycate, topical nasal corticosteroids [in case of failure or insufficiency of those above]).
The prohibited treatments are the oral or injectable corticosteroids and the anti-leukotrienes.
The following demographic data will be collected during the first visit: date of birth, gender, ethnic group, weight, height, smoking habits and alcohol use status.
Medical history, treatment history, concomitant treatments and patient's physical examination will also be documented during V0.
The allergy must be confirmed by positive skin test and/or the presence of IgE for grasses (prick test defined as positive if higher than or equal to half the negative control; IgE are positive if at least class 3 (≥ 3.5 kU / L); these tests must have been made at the latest during the first visit.
A patient diary will be given to each patient:
- For evaluation of the total 5 symptoms score T5SS and rescue medication RS, it is essential that patients note every day the symptoms (sneezing, rhinorrhoea, nasal pruritus, itching and/or eye tearing and nasal obstruction) intensity, and the rescue medications, in their patient diary.
- It is also essential that the patient takes note every day of his/her QoL by filling in three questions included in his/her diary card: Did you sleep well? - Can you work normally? - How do you feel?
- It is also imperative that patients note the date of the start of treatment and the date of onset of symptoms.
This patient diary will be given to the patient at each visit, and will be brought back at the next visit, it will be reviewed and validated by the investigator and will be part of the Case Report Form.
All relevant (related to allergy) concomitant medications taken by the patient during the study period will be recorded at each visit in the CRF.
The AEs and SAEs will be recorded at V1 and V2 in order to assess safety.

Measure Description |
Time Frame |
---|---|---|
Area Under the Curve [AUC](Total Score of Symptoms Taking Into Account the Total 5 Symptom Score (T5SS) and Consumption of Rescue Medications (RM) on the Y-axis, and Time on X Axis)
Time Frame: Up to Month 6 (end of pollen season)
|
Area under the curve [AUC] (total score of symptoms taking into account the Total 5 Symptom Score (T5SS) and consumption of rescue medications (RM) on the Y-axis versus time on X axis).
T5SS was the sum of the 5 individual scores (min-max=0-15).
It was corrected each day as a function of consumption of rescue medications (RM): oral antihistamine (+2 points), local treatment (nasal or eye; +1 point), ocular cromoglycate (+1 point) and nasal topical corticosteroids (+1 point).
An increase in the total corrected score was considered as a worsening of the allergic symptoms.

Up to Month 6 (end of pollen season)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Quality of Life During the Whole Period of Observation
Time Frame: QoL scores were assessed daily for up to 6 months
|
This is the mean of the score to 3 daily quality of life questions: 1) Did you sleep well (0 to 3), 2) Are you able to work (0 to 3), 3) How do you feel today (0 to 3).
The minimum daily score is 0 (good quality of life) and the maximum is 9 (bad quality of life).
The mean of the daily scores was calculated over the whole period of observation (up to 6 months) for each patient.

QoL scores were assessed daily for up to 6 months
