What to feed child with peanut allergy
Food contains additives for numerous reasons, such as to preserve it, to help make it safe to eat for longer, and to give colour or texture.
All food additives go through strict safety testing before they can be used. Food labelling must clearly show additives in the list of ingredients, including their name or «E» number and their function, such as «colour» or «preservative».
A few people own adverse reactions to some food additives, love sulphites, but reactions to ordinary foods, such as milk or soya, are much more common.

Four ways to take control of peanut allergies
Bjelac recommends these four steps to protect your kid from the unthinkable — while avoiding a police state in the process:
Prevent peanut allergy
Eat the peanut. Wait, what? Take a lesson from the Israelis. Unlike American children, who were often told to wait till age 3 to eat peanuts, Israeli children are exposed as babies. And they own far less peanut allergies than Americans.
“One of their first finger foods is called Bamba — a puffed peanut butter snack. I call them the Cheerios of Israel,” says Dr.
Bjelac. “We now understand that the earlier you eat a food, the more likely your immune system will recognize that its safe.”
Still a little skittish? Dr. Bjelac says to take it slow. “Peanuts shouldnt be your child’s first food. Talk to your pediatrician about how to introduce them.” Some tips for safely introducing your baby to peanut include:
- Mix it up: Start with a little quantity of a peanut product mixed in with fruit puree, or another food that your kid is eating regularly.
- Start small: Feed your baby a little quantity of peanut powder or peanut butter mixed with pureed food and wait 15 minutes.
If your kid has no symptoms, attempt a normal serving size.
- Try other foods first: Make certain your kid is doing well with swallowing purees and other foods before trying a peanut product. That way spitting out the food or gagging will be less likely to happen, which can sometimes be alarming.
- Don’t wait if there’s a problem: If your kid tries a new food and then develops a rash, vomits, has trouble breathing or has any other concerning symptoms, seek immediate medical care.

But here’s some excellent news: “Food allergy reactions remain beautiful rare. We honor every food allergies, but we dont desire parents to be afraid,” notes allergist and immunologist Jaclyn Bjelac, MD.
Dr. Bjelac offers four science-backed tips on how to assist hold your kid allergy-free — or living their best life in spite of a severe peanut allergy.
Team up with an allergy doctor
If your kid has had an allergic reaction to any food, an allergist can assist you figure out what it was and how to manage it. “Parents should be empowered after a visit to an allergy specialist,” notes Dr. Bjelac. Armed with a food allergy action plan, you’ll know about:
- Meds: What medicines your kid should take for certain symptoms.
- Symptoms: What peanut allergy symptoms glance like.
- Labels: How to avoid peanuts by reading food labels.
- EpiPen®: When your kid should use a self-injectable epinephrine device such as EpiPen or Auvi Q.
- Advocate: How to advocate for your kid at school or restaurants.
An allergy doctor can also tell you if your kid is a excellent candidate for immunotherapy to treat their allergy.
Immunotherapy introduces tiny doses of an allergen to desensitize the immune system to it. There are three main types of peanut allergy treatment:
- Oral immunotherapy “OIT”: When the kid eats a little quantity of a food allergen such as peanut, and continues that dose every day to assist them be “bite-proof.” Some patients who pursue this treatment are capable to consume normal serving sizes of the food.
- Epicutaneous immunotherapy, or the “peanut patch”: Sends little amounts of peanut protein through the skin. Currently being studied.
- Sublingual immunotherapy “SLIT”: When extremely little doses of a food allergen is istered under the tongue and absorbed through the mouth.
This “low and slow” process has been shown to confer protection to accidental peanut ingestion in a recent study.
The lowdown on peanut allergies
A peanut allergy is the ultimate irony: Your child’s immune system mistakenly thinks peanuts are dangerous. It then overreacts to the point where eating peanuts becomes, well, dangerous.
“Peanut proteins are extremely allergenic,” explains Dr. Bjelac. “We also believe that the cooking method affects their allergenicity.
Most peanut products consumed in the U.S. are roasted, which increases how allergenic they are.”
And unfortunately, peanut allergies are on the rise, tripling between and Dr. Bjelac estimates that peanut allergies now affect around 3% of U.S. children, or million children and teens.
“While most food allergy is found in childhood, peanut allergies tend to persist into adulthood. Less than 20% of kids will outgrow a peanut allergy,” relates Dr. Bjelac. “But if you empower yourself with the correct information, you and your kid can still own a grand quality of life.”

Peanut Allergy: Early Exposure Is Key to Prevention
Posted on by Dr.

With peanut allergy on the rise in the United States, you’ve probably heard parents strategizing about ways to hold their kids from developing this potentially dangerous condition. But is it actually possible to prevent peanut allergy, and, if so, how do you go about doing it?
There’s an entirely new strategy emerging now! A group representing 26 professional organizations, advocacy groups, and federal agencies, including the National Institutes of Health (NIH), has just issued new clinical guidelines aimed at preventing peanut allergy .
The guidelines propose that parents should introduce most babies to peanut-containing foods around the time they start eating other solid foods, typically 4 to 6 months of age. While early introduction is especially significant for kids at specific risk for developing allergies, it is also recommended that high-risk infants—those with a history of severe eczema and/or egg allergy—undergo a blood or skin-prick test before being given foods containing peanuts. The test results can assist to determine how, or even if, peanuts should be introduced in the youngsters’ diets.
This recommendation is turning older guidelines on their head.
In the past, pediatricians often advised parents to delay introducing peanuts and other common causes of food allergies into their kids’ diets. But in , the thinking began shifting when a panel of food allergy experts concluded insufficient evidence existed to show that delaying the introduction of potentially problematic foods actually protected kids . Still, there wasn’t a strategy waiting to assist prevent peanut or other food allergies.
As highlighted in a previous blog entry, the breakthrough came in with evidence from the NIH-funded Learning Early about Peanut Allergy (LEAP) trial .
That trial, involving hundreds of babies under a year ancient at high risk for developing peanut allergy, established that kids could be protected by regularly eating a favorite peanut butter-flavored Israeli snack called Bamba. A follow-up study later showed those kids remained allergy-free even after avoiding peanuts for a year .
Under the new recommendations, published simultaneously in six journals including the Journal of Allergy and Clinical Immunology, every infants who don’t already test positive for a peanut allergy are encouraged to eat peanut-enriched foods soon after they’ve tried a few other solid foods.
The guidelines are the first to offer specific recommendations for allergy prevention based on a child’s risk for peanut allergy:
- Infants at high risk for peanut allergy—based on severe eczema and/or egg allergy—are suggested to start consuming peanut-enriched foods between 4 to 6 months of age, but only after parents check with their health care providers. Infants already showing signs of peanut sensitivity in blood and/or skin-prick tests should attempt peanuts for the first time under the supervision of their doctor or allergist.
In some cases, test results indicating a strong reaction to peanut protein might lead a specialist to recommend that a specific kid avoid peanuts.
- Infants with mild to moderate eczema should incorporate peanut-containing foods into their diets by about 6 months of age. It’s generally OK for them to own those first bites of peanut at home and without prior testing.
- Infants without eczema or any other food allergy aren’t likely to develop an allergy to peanuts.
To be on the safe side, it’s still a excellent thought for them to start eating peanuts from an early age.
Once peanut-containing foods own been consumed safely, regular exposure is key to allergy prevention. The guidelines recommend that infants—and particularly those at the greatest risk of allergies—eat about 2 grams of peanut protein (the quantity in 2 teaspoons of peanut butter) 3 times a week.
Of course, it’s never a excellent thought to give infants whole peanuts, which are a choking hazard. Infants should instead get their peanuts in prepared peanut-containing foods or by stirring peanut powder into other familiar foods. They might also attempt peanut butter spread on bread or crackers.
In recent years, peanut allergy in the U.S.
has almost quadrupled, making it the leading cause of death due to severe, food-related allergic reactions. The hope is that, with widespread implementation of these new guidelines, numerous new cases of peanut allergy can now be prevented.

Don’t leave home without it (your child’s epinephrine injector)
“I hope you never own to use it, but the epinephrine needs to go wherever your kid goes,” cautions Dr.
Bjelac. “If you ever need it, I dont desire you to wish you had it.
While schools are doing their part with peanut-free tables and snacks, these precautions can make children feel on the outs with their peers. “Parents know their kid better than anyone else. If you know your kid will make brilliant food choices, won’t share food and will enquire for visible peanut residue to be wiped away before sitting below, then your kid can sit with their peers,” relates Dr.
Add to that a surprising silver lining: Most food allergy reactions require mucosal exposure. The peanut has to come in contact with the mouth, inside of the nose or eyes. It’s rare for a kid to react to airborne exposure.
“Peanut proteins dont cause reactions love that. Typically, incidental contact, such as touching surfaces without visible peanut product on them, wouldnt be enough to cause a whole body reaction.”
But her recommendation goes both ways.
“If parents are worried their kid is a risk-taker and likes to share food, the peanut-free table is probably a better choice. But these decisions are not always black and white and need to be made based on the individual kid. And we need to give kids some credit for taking care of themselves, too.”
Imagine not being capable to enjoy a peanut butter and jelly sandwich (or even be around people who are eating one). That is one of numerous concerns that the estimated million American children and teens with a peanut allergy own daily.
Peanut allergy is the most common food allergy in children and that number has been rising – peanut allergy incidence increased 21 percent from to Almost percent of children in the US are thought to own a peanut allergy, according to the American College of Allergy, Asthma, and Immunology (ACAAI).
Despite it being a relatively common problem, there is no cure for peanut allergy.
So, what is being done to develop treatments? First, let’s review what we know about peanut allergy and how we currently manage it.
Peanut allergy overview
Allergies happen when your body’s immune system overreacts to an otherwise innocuous substance, in this case, peanut protein. Although some children may grow out of their peanut allergy, most do not. Therefore, peanut allergy is likely a lifelong affliction that can cause severe allergic reactions upon accidental exposure to peanuts.
Peanut allergy has become infamous for being the leading cause of food allergy-linked death due to anaphylaxis, a extremely severe, sudden-onset side effect of allergies that requires immediate medical attention and can be fatal.
Anaphylaxis symptoms include impaired breathing, throat swelling, sudden blood pressure drop, pale skin, blue lips, dizziness, and fainting. However, an allergic reaction to peanuts may include various other non-fatal (but still unpleasant) symptoms, including indigestion, stomach cramps, vomiting, diarrhea, wheezing, shortness of breath, cough, hives, tongue/lip swelling, or confusion.
Peanut allergy is diagnosed both by empirical data, such as keeping a food diary of any reactions and trying an elimination diet, and lab testing, such as a skin test or blood test.
There are three types of allergy skin tests: the skin prick test, where the skin is pricked so the allergen goes under the skin’s surface; the intradermal skin test, where the allergen is injected correct under the skin’s surface; and patch testing, where a patch containing the allergen is taped to the skin for 48 hours. The blood test measures the levels of peanut-specific immunoglobulin E (IgE), with increasing levels corresponding to the increasing likelihood of peanut allergy. However, a positive skin test doesn’t always mean the patient has a peanut allergy and a negative blood IgE test doesn’t law out a peanut allergy.
To confirm a peanut allergy diagnosis, an oral food challenge, where one ingests little and increasing amounts of peanut under the shut watch of medical professionals, can be used.
Although they run the risk of inducing severe allergic reactions or anaphylaxis, oral food challenges are generally safe because they are performed under medical supervision with save medication, such as epinephrine, readily available. These tests can also provide peace of mind, either way, to confirm or law out a peanut allergy diagnosis.
Historically, peanut avoidance was considered the first line of treatment for anyone at risk of developing a peanut allergy.
However, the National Institute of Allergy and Infectious Diseases (NIAID) completely reversed their recommendations for children at risk of peanut allergy in after the Learning Early About Peanut allergy (LEAP) trial showed that children at high risk for having peanut allergy were less likely to develop an allergy if they were exposed to peanuts within their first 12 months of life. Of the infants at high risk of developing a peanut allergy, only percent who were introduced to peanuts early on developed a peanut allergy by age 5 compared to percent who avoided peanuts.
This provided hope that peanut allergies may actually be prevented by exposing children to peanuts early enough if they haven’t yet developed a peanut allergy.
The updated guidelines outlined when children should be introduced to peanuts based on their allergy risk: high-risk children (with severe eczema, egg allergy, or both) around months, moderate-risk children (with mild-to-moderate eczema or other food allergies) around 6 months, and low-risk children (without eczema or food allergies) at their parent’s discretion.
High-risk children should be tested for peanut allergy by an allergist before introducing them to peanuts to ensure they aren’t already allergic.
For people who already own a peanut allergy, avoidance is still advised. Patients should also carry a save medication, such as an epinephrine injector (the EpiPen, among other brands), at every times in case of accidental exposure. Antihistamines, such as diphenhydramine (Benadryl), may also be used to treat milder allergic reaction symptoms after peanut exposure.
There is no cure for peanut allergy, but there are drugs in development to reduce the severity of symptoms upon exposure to peanuts, allowing patients to potentially avoid severe reactions and anaphylaxis after accidental peanut exposure.
The allergy drug pipeline got a boost in funding during the past few years, especially for drugs that alter the course of allergies and prevent allergic reactions from starting, not just controlling symptoms once they start.
This boost has helped bring drug candidates through clinical trials: as of October 30, , a non-exhaustive search using the keywords “peanut allergy” on gave clinical trial results.
There are no FDA-approved drugs currently, but the top drug candidates are vying for FDA approval in early Here’s an overview of the major drugs in the pipeline for peanut allergy.
Note: This is not meant to be an exhaustive list of drugs in development, but a summary of later-stage and some exciting early-stage drugs in the pipeline.
Palforzia (AR) [Aimmune Therapeutics] – oral immunotherapy (OIT)
Palforzia, formerly called AR, is a biologic oral immunotherapy that trains the patient’s immune system to become desensitized to peanuts over time.
This isn’t a traditional drug – it’s essentially carefully measured defatted protein flour in specific doses that patients can add to their food. The powder is portioned to deliver exact amounts of peanut protein, building up to a maintenance dose of mg (corresponding to about one peanut kernel).
Patients first undergo a dose escalation period where they add Palforzia to food and gradually increase the dose they ingest over about a 6-month period. Patients then enter the maintenance period where they continue taking a therapeutic dose of Palforzia daily.
Aimmune’s Phase 3 trial, Peanut Allergy Oral Immunotherapy Study of AR for Desensitization in Children and Adults (PALISADE), studied how effectively Palforzia improved peanut tolerance in peanut-allergic people ages The largest effect was seen in children and teens ages 67 percent of participants ( of ) who received Palforzia could ingest mg or more of protein powder (about 2 peanut kernels) without moderate to severe symptoms, compared to only 4 percent of participants (5 of ) who received placebo.
Only 10 percent of participants ages who received Palforzia needed to use save epinephrine for their symptoms during the food challenge at the finish of the maintenance period, compared to 53 percent who received a placebo. The lack of efficacy seen in adults ages could be due to little sample sizes (only 41 participants received Palforzia and 14 received placebo).
The major downside to oral immunotherapy is its ability to increasethe risk of anaphylaxis. This shouldn’t be surprising – if you’re ingesting the food you’re allergic too, even in little and controlled doses, you would expect to own some side effects, especially when you start scaling up the doses to induce desensitization to the allergen.
Palforzia doesn’t seem to be an exception: more than 95 percent of participants ages who received either Palforzia or placebo had an adverse event during the intervention period.
This increased risk of side effects largely accounts for the noticeably high number of patients that withdrew during the study: 22 percent of participants ages (80 of ) and 54 percent of participants ages (22 of 41) who received Palforzia withdrew from the study, compared to 8 percent of participants ages (10 of ) and 7 percent of participants ages (1 of 14) who received placebo.
An open-label roll-over study from PALISADE (ARC) showed that an additional 28 weeks of daily Palforzia maintenance dosing increased the patients’ ability to tolerate higher concentrations of peanut.
Eighty percent of patients could tolerate 1, mg of peanut protein (about peanut kernels) and 49 percent could tolerate the highest dose of 2, mg (about peanut kernels). This shows the sustained efficacy of Palforzia and that there were less adverse events as dosing continues, likely due to the increased desensitization.
Aimmune has additional Phase 3 trials, including the Real-World AR Market Supporting Experience Study in Peanut-Allergic Children (RAMSES) to assess the safety and efficacy of Palforzia in children ages without requiring an initial food challenge, and AR Trial in Europe Measuring Oral Immunotherapy Success (ARTEMIS) to study the safety and efficacy of Palforzia in children ages at various trial sites in Europe.
Despite the risk of side effects, Palforzia is still highly effective at desensitizing people with peanut allergy, ultimately allowing them to prevent major allergic reactions in case of accidental peanut ingestion.
Palforzia received FDA Quick Track Designation in and Breakthrough Designation in In March , the FDA accepted Palforzia’s Biologics License Application (BLA) and aims to review it by tardy January Most recently in September , the FDA’s Allergenic Products Advisory Committee (APAC) voted to support Palforzia’s use in children and teens with peanut allergy. The FDA’s decision is expected in early
Rose Joachim, PhD, a Senior Healthcare Analyst at GlobalData, told BioSpace, “The FDA advisory committee’s strong support for Aimmune’s Palforzia suggests that despite the drug not being a perfect fit for every patient with a peanut allergy, the therapy still has grand potential to address key unmet needs in the US.”
Viaskin Peanut [DBV Technologies] – epicutaneous immunotherapy (EPIT)
Viaskin Peanut is a patch worn on the skin that delivers extremely little amounts of peanut allergen (usually microgram amounts versus milligram quantities used in oral immunotherapy) into the top few layers of skin, allowing the immune system to interact with the antigen (in this case peanut protein).
Epicutaneous immunotherapy offers benefits over oral immunotherapy, such as using much lower doses of antigen, avoiding allergen ingestion, and having less systemic side effects.
Viaskin Peanut received Quick Track Designation in followed by Breakthrough Designation in However, DBV hit a mild bump in the road in October when their Phase 3 trial, Peanut Epicutaneous Immunotherapy (EPIT) Efficacy and Safety (PEPITES), failed to meet the primary endpoint- a «15 percent lower bound of the confidence interval» between response rates in the patch and placebo groups. Despite missing the preset mark, the Viaskin Peanut patch significantly improved desensitization: 35 percent of participants ages who wore the Viaskin patch containing μg peanut protein were desensitized at the food challenge at the finish of the study versus 14 percent of participants who wore a placebo patch.Viaskin Peanut was also well-toleratedand the withdrawal percentage was low in each group: only percent of the Viaskin-wearing participants and percent of the placebo-wearing participants dropped out.
Another Phase 3 study, Genuine Life Use and Safety of Epicutaneous Immunotherapy (REALISE), studied the safety of Viaskin Peanut ( μg) in participants ages in a routine clinical setting.
The results agreed with other studies and showed that it was well-tolerated with serious adverse events occurring in only 3 participants (1 percent) who wore the Viaskin patch and 2 participants (2 percent) who wore the placebo patch. The most commonly reported side effect was mild to moderate local application site reactions.
DBV has various other ongoing trials, including the Phase 3 Epicutaneous Immunotherapy in Toddlers with Peanut Allergy (EPITOPE) study looking at the safety and efficacy of Viaskin Peanut ( μg and μg) in participants ages
Despite the desensitization difference not being statistically significant between Viaskin Peanut and the placebo patch, DBV continued testing and still pursued FDA approval by filing a BLA in October It was poised to be the first peanut allergy drug to enter the market with an FDA decision expected in August , but DBV Technologies withdrew its BLA in December This decision was made after consulting with the FDA, based on questions raised by the agency and the need for more manufacturing data, not due to any safety concerns.
DBV submitted a new BLA in August , which was accepted by the FDA in early October The FDA aims to review the BLA by August 5,
“Although Viaskin Peanut’s epicutaneous therapy has failed to protest the same degree of efficacy in comparison to Palforzia, Viaskin Peanut’s safety profile may afford it a unique niche in the market,” Joachim added. “This includes the treatment of patients with extreme peanut sensitivity, who otherwise might not qualify for treatment with oral immunotherapy, as well as little children.”
CA [Camallergy] – oral immunotherapy (OIT)
CA is a peanut protein-based biological drug for oral immunotherapy, much love Palforzia.
The initial dosing stage is set up slightly differently (a single dose at the initial appointment and a 7-stage dose escalation period completed in 4 months or less), but the overall thought of increasing the dose of peanut protein and then maintaining a steady dose indefinitely is the same.
Their proof-of-concept Phase 1 trial, Study of Tolerance to oral Peanut (STOP), studied the safety and efficacy of CA in 22 UK children ages with peanut allergy. Every 22 children gradually increased dosing every 2 weeks, then the mg maintenance dose was maintained for 30 weeks.
Eighty-six percent of participants (19 of 22) tolerated the dose increases and maintenance doses at mg, while 9 percent (2 participants) tolerated dose increases and maintenance doses up to mg. Only 1 participant (5 percent) withdrew from the study. Reactions occurred in 86 percent of participants with most being mild and none being serious adverse events. At the finish of the week maintenance period, 64 percent of participants (14 of 22) could tolerate 6, mg of peanut protein, which is a fold increase from the median initial tolerated quantity (6 mg).
The Phase 2 STOP2 trial showed the safety and efficacy of CA compared to standard of care (peanut avoidance) in UK children ages In the first phase of the study, 62 percent of participants (24 of 39) who received CA could tolerate mg of peanut protein compared to none of the 46 participants who received standard of care.
Eighty-four percent of participants who received CA could tolerate an mg daily dose of peanut protein. In the second phase, the standard of care participants received CA Fifty-four percent and 91 percent could tolerate mg and mg, respectively, of peanut protein. Mild side effects occurred in most patients, with gastrointestinal symptoms being the most common (31 participants had nausea and 31 had vomiting).
The STOP3 Phase 3 trial is not yet enrolling but will glance at the safety and efficacy of CA in participants ages 4 and older with peanut allergy.
“Although it has shown promise in early phase clinical studies, at this point it is unclear how CA will be capable to differentiate from Palforzia, which is already so much further ahead in development,” Joachim commented.
PRT [ProTA Therapeutics] – oral immunotherapy (OIT) and probiotic combination
PRT is a unique combination of peanut protein oral immunotherapy and a probiotic (the bacteria Lactobacillus rhamnosus).
This combination therapy specifically leverages the immune-altering actions of probiotic bacteria to shift a patient’s immune response away from peanut allergy towards tolerance and sustained unresponsiveness (remission) – essentially a cure.
“Aimmune’s Palforzia and DBV’s Viaskin Peanut might be the biggest names in the news, but other later-stage products could prove to be significant additions to the market because they address some of the pioneering products’ weaker points, especially the requirement for ongoing maintenance therapy to ensure protective desensitization against peanuts,” Joachim said. “One of the most exciting products in this regard is PRT”
The effects of probiotics on allergies own been studied previously.
Lactobacillus rhamnosus, specifically, has been shown to prevent pollen-induced asthma in mice and even reduce airway allergies in mice whose mothers were exposed to the bacteria while they were pregnant. These results make Lactobacillus rhamnosus an exciting agent for allergy treatment.
There are four possible outcomes to treating food allergies. Desensitization is the increased reaction threshold to an allergen, which requires continues therapy to maintain its effects. Sustained unresponsiveness, also called remission, is thought to be a “reprogramming of the immune response to the allergen” where one can tolerate the allergen weeks or months after treatment is stopped.
Long-term sustained responsiveness is the ability to tolerate the antigen years after the treatment stopped and may propose possible tolerance but non-responsiveness to allergen can’t be guaranteed.
Finally, tolerance is the finish and “permanent” lack of response to an allergen after treatment is stopped (although “permanent” is generally a subjective quantity of time).
The Phase 2a proof-of-concept trial in 62 Australian children ages evaluated how numerous children showed sustained unresponsiveness (remission) up to weeks after stopping PRT treatment. The participants either received PRT (31 children) or placebo (31 children) for 18 months following an 8-month dose escalation and month maintenance phase oral immunotherapy schedule.
Ninety percent of participants (26 of 29) who received PRT were desensitized to 4 g of protein powder on the final day of maintenance treatment compared to 7 percent of participants (2 of 28) who received a placebo. Those patients were examined weeks after stopping treatment for sustained unresponsiveness, which was seen in 82 percent of participants (23 of 28) who received PRT compared to 3 percent of participants (1 of 28) who received a placebo.
Every but 1 patient who achieved sustained unresponsiveness was still consuming anywhere from 5 peanuts to 3 tablespoons per week without allergic reaction 3 months after treatment ended. Not surprisingly, more PRTtreated participants reported adverse events than those taking a placebo (34 taking PRT and 15 taking placebo).
Forty-eight children from this proof-of-concept study were enrolled in a 4-year follow-up study to track their sustained unresponsiveness.
Of the participants who achieved sustained unresponsiveness at the finish of the proof-of-concept trial, 70 percent had long-lasting tolerance 4 years after stopping treatment. Numerous more participants who received PRT continued to eat peanuts (16 of 24 participants, 67 percent) compared to participants who received placebo (1 of 24 participants, 4 percent).
A Phase 2b trial in Australian children ages is evaluating the sustained unresponsiveness (remission) rate in a larger population. This trial is not only comparing PRT to a placebo but also to regular peanut oral immunotherapy (without probiotics).
Every participants were enrolled as of May and the study is currently ongoing.
“With top-line results from this trial expected in Q1 , the field will soon study whether PRT’s success in early phase trials can be replicated in a larger population of patients,” Joachim added. “If successful, it could own huge implications for the field.”
Dupixent (Dupilumab) [Regeneron] – anti-IL-4R antibody
Dupixent is an injectable anti-interleukin-4 receptor (IL-4R) antibody currently approved for atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis (CRSwNP). IL-4R is a protein involved in immune response, specifically IL-4 and IL signaling, which regulates IgE production and, ultimately, allergic responses.
Dupixent is also being developed for peanut and grass pollen allergy (among other indications) in collaboration with Sanofi.
A currently recruiting Phase 2 trial is studying whether Dupixent can increase peanut protein tolerability compared to placebo in an estimated 48 children ages
Interestingly, Regeneron, Sanofi, and Aimmune announced a partnership in October to study Dupixent with Palforzia as a combination therapy. A currently recruiting Phase 2 trial is expected to enroll children years ancient to study whether Palforzia with Dupixent improves desensitization to mg of peanut protein compared to Palforzia with placebo.
Whether the Dupixent-Palforzia combination induces sustained unresponsiveness will also be explored.
“Several monoclonal antibodies are in development for peanut allergy, including Sanofi/Regeneron’s Dupixent,” Joachim said. “Although these types of agents could be useful tools in limiting the side effects of peanut immunotherapy, it is unclear how practical the use of expensive biologics will be in the long-term treatment of peanut allergy.”
Etokimab (ANB) [AnaptysBio] – anti-IL antibody — no longer being pursued for peanut allergy
Etokimab, previously called ANB, is also not specific to peanut allergy – it is an anti-interleukin 33 (IL) antibody.
IL is an immune system protein (called a proinflammatory cytokine) that plays a role in numerous allergic diseases, such as atopic dermatitis, food allergies, and asthma. Etokimab was previously shown to be well-tolerated and safe in 96 healthy volunteers istered either subcutaneously or intravenously.
A proof-of-concept Phase 2a study in 20 participants with moderate to severe peanut allergy showed debatably positive results.
Forty-seven percent of participants (7 of 15) who received one dose of Etokimab could tolerate mg of peanut protein 14 days after istration compared to 40 percent of participants (2 of 5) who received a placebo. After removing four patients, two patients from each group, because they “exhibited mild symptoms at baseline,” the data looked much more impressive: 46 percent of participants (6 of 13 who received Etokimab could tolerate mg of peanut protein compared to none of the 3 participants who received a placebo.
Although AnaptysBio was reported to be planning a Phase 2b study, the company decided against pursuing Etokimab for peanut allergy in mid Peanut allergy is also not listed as an indication for Etokimab on the company’s website.
However, Markets Insider said AnaptysBio “may pursue potential investigator-sponsored trials of Etokimab” for peanut allergy.
Early-stage drug highlights
As for drugs in earlier-stage development, there are a few innovative options, including Introimmune Therapeutics’ peanut-containing toothpaste as oral mucosal immunotherapy and Vendanta Biosciences’ human microbiota-derived bacteria drug VE A Phase 1b/2 trial studying VE alone and in combination with peanut oral immunotherapy is currently ongoing and is expected to enroll 40 participants ages The trial began enrolling in July
“There are a number of products in early clinical development with the potential to shape the peanut allergy market going forward,” Joachim said.
“This includes a variety of injectable allergen immunotherapy products, which glance more similar to the allergy shots patients typically get for seasonal allergies. While original attempts at injectable immunotherapy for peanut allergy led to dangerous side effects, the current products in development seek to avoid and abate the allergic response.”
Aravax’s PVX, an intradermal immunotherapy vaccine for peanut allergy, is one such drug. It contains peptides that mimic portions of major peanut allergens that can train the immune system specifically, which largely reduces the risk of allergic side effects.
The company announced that a Phase 1 trial showed that PVX was safe and well-tolerated.
With the high unmet need in the peanut allergy field and multiple late-stage drugs knocking on the FDA’s door for approval, it may not be surprising that the market for peanut allergy drugs seems extremely bright. GlobalData is forecasting the peanut allergy market to grow an astounding 1,fold from – expanding from a $ million industry in to a $ billion industry by
However, the price tag of these drugs must be considered, as they will likely be a lifelong drug.
The Institute for Clinical and Economic Review (ICER) published a report in April discussing the potential pricing of AR and Viaskin Peanut. The ICER estimated AR would cost $8, for the first year and $4, for each year of maintenance, in comparison to Viaskin Peanut’s estimated cost of $6, per year.
Oral immunotherapy is not a new thought – about of the 5, board-certified allergists in the US already use oral immunotherapy to treat food allergies, including peanut allergy, by using products sold from retail stores, such as peanut flour. Although buying a bag of peanut flour from the grocery store is much cheaper, some allergists emphasize the importance of a standard product and protocol that should give more predictable results and be safer for patients.
Despite celebration about the potential new therapies coming to market, some families and doctors are debating how useful these drugs, especially oral immunotherapy-based ones, will be for patients.
It is significant to remember that these drugs do not offer a cure, they own side effects, and may not work for everyone. However, they may provide more protection against severe allergic reactions from accidental peanut exposure and, therefore, some peace of mind for patients.

To prevent a reaction, it is extremely significant that you avoid peanut and peanut products. Always read food labels to identify peanut ingredients.
If you are allergic to peanuts, you own a 25 to 40 percent higher chance of also being allergic to tree nuts.1 Also, peanuts and tree nuts often touch one another during manufacturing and serving processes.
Discuss with your allergist whether you need to also avoid tree nuts.
Peanuts are one of the eight major allergens that must be listed on packaged foods sold in the U.S., as required by federal law.
Avoid foods that contain peanuts or any of these ingredients:
- Mandelonas (peanuts soaked in almond flavoring)
- Mixed nuts
- Beer nuts
- Monkey nuts
- Ground nuts
- Arachis oil (another name for peanut oil)
- Nut pieces
- Lupin (or lupine)—which is becoming a common flour substitute in gluten-free food.
A study showed a strong possibility of cross-reaction between peanuts and this legume, unlike other legumes.
- Artificial nuts
- Peanut flour
- Peanut butter
- Cold-pressed, expelled or extruded peanut oil*
- Nut meat
- Peanut protein hydrolysate
*Highly refined peanut oil is not required to be labeled as an allergen. Studies show that most people with peanut allergy can safely eat this helpful of peanut oil. If you are allergic to peanuts, enquire your doctor whether you should avoid peanut oil.
But avoid cold-pressed, expelled or extruded peanut oil—sometimes called gourmet oils.
These ingredients are diverse and are not safe to eat if you own a peanut allergy.
Other Possible Sources of Peanut
Peanuts can be found in surprising places.
While allergens are not always present in these food and products, you can’t be too careful.
Remember to read food labels and enquire questions about ingredients before eating a food that you own not prepared yourself.
- Candy (including chocolate candy)
- Glazes and marinades
- African, Asian (especially Chinese, Indian, Indonesian, Thai and Vietnamese), and Mexican restaurant food—even if you order a peanut-free dish, there is high risk of cross-contact
- Specialty pizzas
- Ice creams
- Sunflower seeds (which are often produced on equipment shared with peanuts)
- Sweets such as pudding, cookies, baked goods, pies and boiling chocolate
- Alternative nut butters, such as soy nut butter or sunflower seed butter, are sometimes produced on equipment shared with other tree nuts and, in some cases, peanuts.
Contact the manufacturer before eating these products.
- Egg rolls
- Sauces such as chili sauce, boiling sauce, pesto, gravy, mole sauce and salad dressing
- Pet food
- Enchilada sauce
- Vegetarian food products, especially those advertised as meat substitutes
Also, peanut hulls (shells) can sometimes be found in compost, which can be used as lawn fertilizer. Before you hire a contractor, enquire whether they use peanut hulls in their compost so you can make an informed decision.

How will I know if my kid has a food allergy?
An allergic reaction can consist of 1 or more of the following:
- runny or blocked nose
- a cough
- wheezing and shortness of breath
- swollen lips and throat
- itchy skin or rash
- diarrhoea or vomiting
- itchy throat and tongue
- sore, red and itchy eyes
In a few cases, foods can cause a severe allergic reaction (anaphylaxis) that can be life-threatening.
Get medical advice if you ponder your kid is having an allergic reaction to a specific food.
Don’t be tempted to experiment by cutting out a major food, such as milk, because this could lead to your kid not getting the nutrients they need. Talk to your health visitor or GP, who may refer you to a registered dietitian.
Introducing foods that could trigger allergy
When you start introducing solid foods to your baby from around 6 months ancient, introduce the foods that can trigger allergic reactions one at a time and in extremely little amounts so that you can spot any reaction.
These foods are:
- shellfish (don’t serve raw or lightly cooked)
- eggs (eggs without a red lion stamp should not be eaten raw or lightly cooked)
- foods that contain gluten, including wheat, barley and rye
- seeds (serve them crushed or ground)
- cows’ milk
- nuts and peanuts (serve them crushed or ground)
See more about foods to avoid giving babies and young children.
These foods can be introduced from around 6 months as part of your baby’s diet, just love any other foods.
Once introduced and if tolerated, these foods should become part of your baby’s usual diet to minimise the risk of allergy.
Evidence has shown that delaying the introduction of peanut and hen’s eggs beyond 6 to 12 months may increase the risk of developing an allergy to these foods.
Lots of children outgrow their allergies to milk or eggs, but a peanut allergy is generally lifelong.
If your kid has a food allergy, read food labels carefully.
Avoid foods if you are not certain whether they contain the food your kid is allergic to.
