A prospective, randomized, double-blind placebo-controlled multicentre study with mannan-conjugated birch pollen allergoids administered subcutaneously to adolescent and adult patients with birch pollen-induced allergic rhinitis or rhinoconjunctivitis.
This study is investigating a new treatment for birch pollen allergy. If you're 18 or older and suffer from a runny nose, sneezing, or itchy eyes due to birch pollen, this research might be for you. We're comparing a new allergy treatment with a dummy treatment (a placebo) to see how well it works. Participants will receive injections and we’ll track their symptoms and any allergy medicines they use during the 2024 birch pollen season. This is a very important stage of testing to confirm if the treatment is effective and safe before it could potentially be made widely available. The goal is to find better ways to help people manage their birch pollen allergies.
At a glance
What is this study about?
This study is all about finding a better way to treat birch pollen allergies. Many people in the UK suffer from symptoms like sneezing, a runny nose, or itchy, watery eyes when birch trees release their pollen. This can make spring a very uncomfortable time of year.
Researchers are testing a new treatment that aims to make your body less sensitive to birch pollen. Think of it like training your immune system to not react so strongly. To do this fairly, some people will get the new treatment, and others will get a 'dummy' treatment, called a placebo. The placebo looks exactly like the real treatment but doesn't contain the active medicine. Neither you nor your study doctor will know which one you are receiving – this is to make sure the results are as fair and accurate as possible.
We will be looking closely at how participants feel during the birch pollen season in 2024. We'll compare how many allergy symptoms people have and how much extra allergy medicine they need to take. This will help us understand if the new treatment really makes a difference to people's lives. This type of study is a very important step before a new medicine can be approved for general use.
Key takeaways
- Tests a new treatment for birch pollen allergy.
- Compares it to a dummy treatment (placebo) to see if it works.
- Looking for adults aged 18+ with birch pollen allergy.
- You'll get injections and record symptoms during spring 2024.
- Aims to find better ways to manage birch pollen allergies.
- Participation is voluntary, and you can leave at any time.
Who may be eligible?
This study is looking for adult volunteers, aged 18 years or older. You can be any gender to take part.
To be eligible, you must have been diagnosed with an allergy to birch pollen. This means you experience symptoms like a runny nose, sneezing, or itchy, watery eyes specifically when birch pollen is in the air.
The study team will check your full medical history and current health to make sure it's safe for you to take part and that the study is a good fit for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you get a runny nose, sneezing, or itchy eyes because of birch pollen?
- Are you able to attend clinic visits regularly?
- Are you willing to record your symptoms and medication use?
What does participation involve?
If you decide to join this study, you will receive a series of injections over a period before the 2024 birch pollen season. These injections will either contain the active new treatment or a placebo (a dummy treatment). You won't know which one you're getting, and neither will your study doctor, to keep the results fair. During the 2024 birch pollen season, you'll need to regularly record your allergy symptoms, such as sneezing or runny nose, and also keep track of any allergy medications you take. This will likely involve using a diary or an app. You'll also have several visits to the study clinic for assessments and check-ups. The total duration of your participation, from your first visit to your last follow-up, will be several months, covering the treatment period and the critical pollen season observation.

Common questions
What is a 'placebo'?
A placebo is a 'dummy' treatment that looks exactly like the real medicine but contains no active ingredients. It helps researchers check if the new medicine works better than no treatment at all.
Will I know if I'm getting the real treatment or the placebo?
No, neither you nor your study doctor will know whether you are receiving the real treatment or the placebo. This helps ensure fair and accurate results.
What does 'birch pollen season' mean?
Birch pollen season refers to the time of year, usually spring, when birch trees release their pollen into the air, causing allergy symptoms for sensitive individuals.
What will I have to do if I join the study?
You'll receive injections, regularly record your allergy symptoms and any medications you take, and attend several clinic visits for checks and assessments.
How long will the study last for me?
Your participation will last for several months, including the period of treatment and monitoring during the 2024 birch pollen season.
