About this study

Official title: 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.

Read more

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 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.

What is being measured

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

  1. 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)

    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.

    Measured: Up to Month 6 (end of pollen season)

Secondary outcomes (1)
  1. Quality of Life During the Whole Period of Observation

    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.

    Measured: QoL scores were assessed daily for up to 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 2LALERG in people with Seasonal Allergy, run by Labo'Life at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 Dec 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?

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)). 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 30 Sep 2020.
