简要总结

PQGrass309 is aimed at exploring the expected average treatment effect of PQ Grass 27600 SU cumulative dose on symptom and medication score in a field setting. The study will enrol adult subjects with seasonal allergic rhinitis and/or rhinoconjunctivitis (SAR) induced by grass pollen exposure.

详细描述

PQGrass309 is a randomised, double-blind, placebo-controlled exploratory study to explore the efficacy and safety of PQ Grass 27600 SU in subjects with seasonal allergic rhinitis and/or rhinoconjunctivitis (SAR) induced by grass pollen exposure. The study is expected to be conducted in the United States (US) and the European Union (EU). The study will enrol enough subjects to allow treatment of approximately 150 subjects.

The aim of this exploratory field study is to explore amongst others the following:

  • The efficacy and safety (up to 6 months following treatment) of a cumulative dose of 27600 standardised units (SU) of PQ Grass in the treatment of grass pollen allergy.
  • The expected average treatment effect on combined symptom and medication score.

入选标准

  • Informed Consent
  • Capable of giving signed informed consent and demonstrates willingness to comply with the requirements and restrictions listed in the ICF and study protocol and to attend required study visits.
  • Subject who has signed and dated the ICF.
  • 18 to 65 years of age inclusive, at the time of signing the ICF.
  • Sex / Contraceptive requirements:
  • Male or female.
  • Female subjects who are not of childbearing potential (defined as at least 12 months natural spontaneous amenorrhoea, or at least 6 weeks following surgical menopause) or females of childbearing potential who agree to comply with the contraceptive requirements of the study protocol.
  • Subjects and general health characteristics:
  • Good general health, as determined by the investigator, based on a medical evaluation, including medical history, physical examination, and laboratory tests. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the investigator agrees that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Positive history of moderate to severe symptoms of seasonal allergic rhinitis and/or rhinoconjunctivitis ascribed to grass (Pooideae) pollen exposure that required repeated use of antihistamines, nasal corticosteroids, and/or leukotriene modifiers for relief of symptoms during the last 2 consecutive seasons prior to the study, confirmed by subject records.
  • Please note: Subjects with asthma may be included, but the asthma must be well controlled (according to current Global Initiative for Asthma {GINA} guidelines [GINA, 2020]).
  • A positive SPT for grass pollen (wheals [longest diameter] ≥3 mm and histamine ≥3 mm) and a negative SPT to the negative control (wheal diameter =0) at screening.
  • Grass specific IgE class ≥2 as documented by an ImmunoCAP test at screening.
  • FEV1 ≥80% of predicted, with a FEV1/FVC ratio ≥70% and (PEFR) ≥75% predicted at screening.
  • Subjects who have no suspicion or symptoms of SARS-CoV-2 infection (as assessed by the investigator) or who have had no contact with a confirmed case of COVID-19 in the past 2 weeks prior to screening and randomisation.
  • Exclusion Criteria (include amongst others):
  • Medical conditions:
  • Pregnant or lactating subject.
  • Moderate to severe allergy symptoms during the screening and treatment periods, and/or GPS caused by perennial allergens or seasonal allergens (other than grass) as verified by medical history and positive SPT.
  • Exception: screening, treatment and collection of eDiary data can be conducted outside of the pollen season(s) of concern or perennial allergies are irrelevant due to avoidance measures (e.g., cats and dog allergy).
  • Subjects with a positive SPT at US and EU sites in regions with relevant southern grass (Bahia grass, Bermuda grass or Johnson grass) exposure.
  • Moderate to severe symptoms during the 3 years prior to Visit 1 to another seasonal or perennial allergen not tested in the SPT that cannot be avoided during the study and the symptoms of which may interfere with administration of treatment and /or impact the data collected, as determined by the investigator.
  • Presence of any medical condition that may reduce the ability to survive a serious allergic reaction.
  • History of autoimmune disease including Hashimoto's thyroiditis or other immunological disorder or other diseases (including, but not limited to, malignancy, cardiovascular, gastro-intestinal, hepatic, renal, hematological, neurological, endocrine or pulmonary disease) that in the opinion of the investigator may pose a safety risk or compromise the interpretation of efficacy of the study treatment.
  • Presence of severe or uncontrolled or partly controlled asthma as defined in the GINA guidelines (GINA 2020) or asthma that requires more than a daily dose above 400 mcg of inhaled budesonide or equivalent.
  • Emergency room visit or hospitalisation for asthma in the 12 months prior to screening and randomisation or any history of a life-threatening asthma attack.
  • Presence of non-atopic rhinitis and/or rhino-sinusitis (with or without polyps).
  • Presence of nasal polyps and/or chronic sinusitis.
  • Presence of any acute or chronic ocular disorder, other than allergic conjunctivitis, which could interfere with the evaluation of CPT.
  • Eye surgery within the past 6 months.
  • Presence of any skin conditions (e.g. skin abnormalities, tattoos) which might interfere with the interpretation of the SPT results.
  • Clinical history of Type I diabetes. Subjects with well-controlled Type II diabetes will be allowed to participate at the discretion of the investigator.
  • Any acute infection (including upper respiratory tract infections in the 14 days prior to Visit 2), which in the opinion of the investigator may pose a safety risk to the subject.
  • Clinical history of severe or serious systemic reaction in response to AIT treatment in the past.
  • Clinical history of severe or life-threatening anaphylactic reactions to foods, insect venom, exercise, drugs or idiopathic anaphylaxis.
  • Clinical history of allergy, hypersensitivity or intolerance to the excipients of the IMP.
  • Tyrosine metabolism disorders, especially tyrosinemia and alkaptonuria.
  • Prior/concomitant therapy:
  • History of any allergen SIT.
  • Inability to adhere to the washout periods for Prohibited Medications/Therapies with respect to Visit 1/1a and to refrain from using the medications indicated until after Visit
  • Treatment with a preparation containing MPL (e.g., Cervarix, Shingrix, Fendrix) within 2 years prior to Visit 1 and until after completion of Visit 15 (with the exception of the IMP).
  • Unable to receive epinephrine therapy (i.e., use of epinephrine is contraindicated such as in subjects with hyperthyroidism, uncontrolled hypertension, cardiac arrhythmias, closed angle glaucoma or subjects taking other sympathomimetic).
  • Previous history of epinephrine device use.
  • β-blocker medication (including eye drops), for any indication.
  • Monoamine oxidase inhibitors and tricyclic antidepressants. (Tricyclic antidepressants should be avoided at least 2 weeks prior to screening).
  • Any previous therapy (within 12 months prior to screening) or current therapy with anti IgE (e.g., Xolair) or anti-interleukins (e.g., mepolizumab) or any other therapy with a biologic agent.
  • Unable to refrain from any vaccination (including influenza and any potential vaccine for COVID-19) during the study (unless administered more than 30 days prior to randomisation). Please note: Emergency vaccinations (e.g., tetanus due to injury) can be administered at any time.
  • Current or past therapy (within the previous 5 years) with immunosuppressant drugs or immunomodulatory biologics.
  • Other exclusions
  • Clinical history of drug or alcohol abuse which, in the investigator's opinion, could interfere with the subject's ability to participate in the study.
