Inclusion criteria
. Written informed consent.
. Aged between 12 and 65, both genders
. Positive suggestive clinical history of intermittent or persistent moderate to severe rhinitis /rhinoconjunctivitis according to ARIA classification, with or without moderate intermittent or persistent asthma,according to GEMA 5.0, due to grass and cupressaceae pollen.
. Subjects with a positive skin prick-test (wheal size \>5 mm diameter) to a standardized mixed extract of grass pollen (Phleum pratense, Holcus lanatus, Dactylis glomerata, Poa pratensis, Festuca elatior, Lolium perenne) or to one of the molecular components of the mixture and to a cupressaceae extract. In addition, the largest diameter of the papules must be greater than or equal to that of the histamine.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Women of childbearing age (from menarche) must present a urine pregnancy test with a negative result at the time of joining the trial.
. Women of childbearing potential participating in the trial, should commit to using an appropriate method of contraception. Medically acceptable methods of contraception are intrauterine devices placed at least 3 months in advance, surgical sterilization (for example, tubal ligation), barrier methods, or the use of oral contraceptives.
. Subjects capable of complying with the dosing regimen.
Exclusion criteria
. Subjects with positive prick test to other aeroallergens except for sensitisation to epithelia with occasional exposure and symptoms.
. Subjects with positive prick test to other aeroallergens except for sensitisation to pollen noncoseasonal with cupressus or grasses.
. Subjects who have received prior immunotherapy in the preceding 5 years for any of the allergens tested or a cross-reactive allergen or are currently receiving immunotherapy with any allergen.
. Subjects in which immunotherapy may be subject to an absolute general contraindication according to the criteria of the Immunotherapy Committee of the Spanish Society of Allergy and Clinical Immunology and the European Allergy and Clinical Immunology Immunotherapy Subcommittee.
. Subjects with severe or uncontrolled intermittent or persistent asthma, with an FEV1 \<70% with respect to the reference value despite adequate pharmacological treatment at the time of inclusion in the trial. Likewise, subjects with intermittent or persistent rhinitis / rhinoconjunctivitis with severe symptoms in which the suspension of oral or systemic antihistamine treatment is contraindicated.
. Subjects who have previously had a severe secondary reaction during the prick test diagnostic skin test.
. Subjects treated with beta-blockers.
. Clinically unstable subjects at the time of inclusion in the trial (acute asthmatic exacerbation, respiratory infection, febrile process, acute urticaria, etc.).
