Study summary

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 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.

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.

  • Age ≥18 years, male and female
  • Woman of childbearing age using effective means
  • Patient having the faculties to understand and respect the constraints of the study
  • Symptomatic since at least two seasons and 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 positive if at least class 3 (≥ 3.5 kU / L); these tests must have been performed at the latest at the first screening visit

Exclusion criteria

Exclusion Criteria:

  • Pregnant woman or woman wishing to become pregnant
  • Breastfeeding woman
  • Patient with an acute exacerbation of allergic rhinitis
  • Patient with uncontrolled asthma
  • Immunotherapy received within the last two years
  • Patient with a known lactose intolerance

  • Patient taking nasal or bronchial inhaled on a long term basis (intermittent consumption during the season is permitted provided it is mentioned in the patient's records)
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  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.

    Time frame: Up to Month 6 (end of pollen season)

Secondary outcomes

  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.

    Time frame: QoL scores were assessed daily for up to 6 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 30, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
