Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have severe or unstable asthma, or are on certain asthma treatments, you may not be eligible to participate.

What safety data exists for PVX-108 or similar treatments for peanut allergy?

The research does not provide specific safety data for PVX-108, but a similar treatment, TNX-901, was well tolerated in a study with patients who have peanut allergies.12345

What is the purpose of this trial?

The overall aims of this study are to demonstrate that treatment with PVX108 immunotherapy has an acceptable safety profile and is effective for reducing clinical reactivity to peanut protein in children and adolescents with peanut allergy.

Eligibility Criteria

This trial is for children and adolescents with a doctor-confirmed peanut allergy, demonstrated by specific blood tests and skin prick tests. They must have had a reaction to a small amount of peanut protein in a controlled test. Kids with moderate or severe asthma are excluded, as well as those who've tried desensitizing treatments before.

Inclusion Criteria

Peanut specific serum IgE measured by ImmunoCAP® ≥ 0.7 kilounit allergy specific antibody per litre (kUA/L) at screening
Positive skin prick test to peanut with mean wheal diameter ≥5 mm greater than negative control at screening
Physician-diagnosed immunoglobulin E (IgE) mediated peanut allergy

Exclusion Criteria

Severe or life-threatening reaction during the screening food challenge, at investigator discretion
My asthma is severe or not well-controlled according to GINA standards.
History of or current clinically significant medical conditions or laboratory abnormalities which in the opinion of the investigator would jeopardise the safety of the participant or the validity of the study results

Findings from Research

ASP0892, a peanut DNA vaccine, was found to be well tolerated in both adults and adolescents with peanut allergy, with the most common side effect being mild injection site itching, and no serious adverse events reported.
While ASP0892 did lead to modest increases in specific immune responses (IgG and IgG4), it did not result in significant clinical improvements in peanut allergy symptoms during food challenges.
