What is the trial about?

The TRACE Peanut Study aims to find out exactly how much peanut is safe for the population, so food labelling can be improved.

Food manufacturers generally use ‘may contain nuts’ warnings because they can’t be sure whether products may, by accident, contain peanut. The TRACE Peanut Study aims to find out exactly how much peanut will cause an allergic reaction in those with a peanut allergy by conducting ‘challenges’ on around 100 people. The focus area of the study is on two ‘extrinsic’ factors known to influence allergic thresholds (exercise and tiredness).

The Food Standards Agency, who commissioned the trial, will be able to use this information to improve the clarity of food labelling for peanut-allergic consumers in the UK. 

Am I eligible?

The trial is open to both men and women. To be eligible, you must:

  • Be aged 18 – 45 years
  • Had a peanut allergy diagnosed by a doctor
  • Be prepared to complete a fitness running test (approx 20 mins)

Please note that certain serious illnesses and other conditions may preclude certain individuals from participating, some of these are detailed on the registration page. Women who are pregnant, planning to be pregnant during the study or who are breastfeeding during the study are not eligible for the trial.

If you believe you may be eligible to participate, please click through to the Registration page and complete the form shown.

What’s involved?

You will be invited to attend a screening visit (2hrs) at the research ward in Royal Brompton Hospital, London or Addenbooke’s Hospital, Cambridge – which ever is most convenient for you. At this visit, we will provide you with written information, answer your questions and ask for your informed consent to proceed.

The aim of this visit will be to run some quick tests and decide if you are eligible to continue into the rest of the study, if so we will invite you return for a ‘peanut challenge’. 

A summary of the study is as follows:

Recruitment and Screening (March 2012 – March 2014)

Challenges (May 2013 – April 2016)

Publish final results (May 2016)

*Approximate participation time is 12 months.

Participants will be reimbursed a maximum of £800 for their time. If you attend a screening visit and are found not to be eligible, we will reimburse any reasonable travel expenses you have incurred.

What if I change my mind once the study has begun?

You are free to withdraw from the study at any time, in the event of this we shall ask for your permission to use any data and samples collected up until that time.
