Study summary

The goal of this study is to determine whether Trichuris suis ova, a potential immunomodulator, is safe in adults and children allergic to peanut or tree nuts.

Read the detailed description

Food allergy is a major cause of life-threatening hypersensitivity reactions. Currently avoidance of the allergenic food is the only established method of preventing reactions in allergic patients. This situation impacts significantly the lives of patients, mainly children, and their families. The current increase in the prevalence of allergic diseases, food allergy in particular, in the Western world has been attributed in part to changes in life style. Before the mid 20th century individuals were exposed to numerous bacterial, parasitic and viral agents. Since these times the progress of hygiene has considerably reduced the risk of exposure to these agents. It is thought that this lack of exposure, particularly during childhood, has led to subtle changes in humans' immune system resulting in an increased propensity to develop allergic and autoimmune responses, the so-called hygiene hypothesis. One of the means of reverting this propensity could be exposure to harmless biological agents. One such agent, eggs of the parasite Trichuris suis (Trichuris suis ova, TSO), has been shown to be well tolerated and efficient in patients with inflammatory bowel diseases. This phase I study will assess whether TSO is safe in adults and children with peanut or tree nut allergy.

In context

Nut Hypersensitivity Reclassified

33 studies on the registry are indexed under Nut Hypersensitivity; 9 are open to participants now.

This study's planned enrollment of 18 is below the median of 47 across 20 interventional studies indexed under Nut Hypersensitivity.

Lead sponsor

Beth Israel Deaconess Medical Center is the lead sponsor of 568 studies on the registry; 80 are open to participants now.

Of its 76 completed or terminated interventional studies of FDA-regulated products, 62 (82%) have results posted.

Compared within Nut Hypersensitivity, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Food Hypersensitivity. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Inclusion criteria

  • 18 to 64 years old
  • Positive skin-prick test to peanut or tree nut and a history of significant clinical symptoms within 60 minutes after the ingestion of peanuts or tree nuts.
  • Peanut or tree nut allergy of mild to moderate grade based on the presence of localized or generalized erythema/urticaria/angioedema/oral pruritis, gastrointestinal symptoms, rhinoconjunctivitis, or mild laryngeal edema (voice change/tightening of throat/mild asthma), and the absence of symptoms/signs of severity (marked dyspnea, hypoxia, cyanosis, hypotension, confusion, incontinence, collapse or loss of consciousness)
  • Otherwise in good health
  • Ability to provide written

Exclusion criteria

Exclusion Criteria:

  • History of severe anaphylaxis to peanut as defined by hypoxia, hypotension, or neurological compromise (cyanosis or SpO2 \< 92% at any stage, confusion, collapse, loss of consciousness, or incontinence)
  • Poor control of atopic dermatitis or current flare requiring an increase in atopic dermatitis medication
  • Inability to discontinue antihistaminic for skin testing
  • Severe persistent asthma as defined by the NHLBI criteria
  • Asthma that requires oral
  • Asthma that has been controlled for less than 1 year
  • \<80% at the screening visit or immediately before the 1st administration of TSO
  • Currently being treated with greater than medium daily doses of inhaled corticosteroids, as defined by the NHLBI guidelines
  • Abnormal blood cell count
  • Abnormal renal function (creatinine above twice the )
  • Abnormal hepatic tests (, ALT above twice the upper limit of normal range)
  • Allergy to Trichuris species
  • Currently treated with anti-helminthic medication
  • Previous treatment with therapy, cytotoxic chemotherapy or lymphoid irradiation for any reason
  • Insulin dependent diabetes
  • History of -1, HTLV-1 or Lyme disease
  • Significant physical or mental disease that would preclude successful compliance and participation in the study, or, in the opinion of the investigators, constitute a hazard, such that enrollment in the study would not be in the subject's best interest
  • Presence or history of cancer of any type except successfully treated basal cell or squamous cell carcinoma of the skin
  • History of alcohol or drug abuse in the last 12 months; chronic liver or biliary disease
  • Pregnancy and lactation; women of child bearing potential must have a documented negative pregnancy test at entry and at each visit during the study, and must be willing to practice adequate during the duration of the study
  • History of parasitism or positive stool determination for ova or parasite at screening
  • Unwillingness or inability of patients (or caregivers) to give written consent or to follow the protocol successfully, including coming to the clinic every 2 weeks for about 4 months
  • Currently participating in a study using an new drug
  • Participation in any interventional study for the treatment of food allergy in the past 6 months
  • Presence in the household of an immunodeficient or immunosuppressed individual
Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
