Study summary

Background:

The disease leukocyte adhesion deficiency type 1 (LAD1) affects white blood cells. Those are immune system cells. In people with LAD1, white blood cells do not properly communicate with the rest of the body. This causes uncontrolled inflammation, particularly in the gums. People with LAD1 can get frequent infections and tend to lose their teeth before adulthood. Researchers want to see if a drug called ustekinumab helps people with LAD1.

Objective:

To study the safety and tolerability of ustekinumab in treating gum inflammation in people with LAD1.

Eligibility:

People ages 12 65 with LAD1

Design:

Participants will be screened with:

  • Medical history
  • Physical exam
  • Oral exam
  • A scan of the chest, abdomen, and pelvis for possible infection
  • Blood and urine tests

The baseline visit will take 2 days. Participants will:

  • Repeat most screening tests
  • Have a skin exam
  • Have small pieces of their gums removed (biopsy)
  • Have mouth fluids collected
  • Get the study drug injected under the skin of the abdomen, thigh, or elsewhere on the body. They will be watched for at least 2 hours.

Participants will be instructed on tracking how they are feeling and any side effects.

Participants will have 4 more visits over 40 weeks. They will get the study drug and repeat the baseline tests.

Participants may have up to 5 more tissue biopsies.

Participants will be called between visits to discuss how they are feeling and side effects.

Participants will have a final visit 52 weeks after the baseline. They will repeat most of the baseline tests.

Participants will answer questions about their oral ulcers.

Read the detailed description

Lymphocyte adhesion deficiency type 1 (LAD1) is an autosomal recessive disorder of leukocyte function. Decreased expression of the \<=2 subunit of leukocyte integrins results in abnormal cell-cell and cell extracellular matrix adhesion. This disease is characterized by recurrent bacterial infections, impaired wound formation, and other aberrations of adhesion-dependent functions. The severe phenotype can be fatal, but patients with even moderate phenotypes are prone to infection and lose their teeth despite treatment.

Ustekinumab is a monoclonal antibody directed against the p40 subunit of human interleukins IL-12 and IL-23. It is approved for treatment of moderate-to-severe plaque psoriasis, active psoriatic arthritis, and moderate-to-severe Crohn s disease. By binding the shared p40 subunit of IL-12 and IL-23, ustekinumab exerts clinical effects through interruption of the TH1 and TH17 cytokine pathways. Previous work at the NIH suggests that blockade of IL-17, which is highly expressed in the gingiva of people with LAD1, can reduce bacterial load and resolve inflammatory gingival disease. We have treated one patient with ustekinumab for 1 year; during this time, he had no serious infections and there was a dramatic resolution of his inflammatory lesions. Our goal is to explore the potential of ustekinumab as treatment for LAD1 inflammatory disease.

The objective of this open-label, proof-of-concept study is to evaluate the safety and tolerability of ustekinumab in 10 patients with LAD1. Participants will receive 5 doses of ustekinumab via subcutaneous injection over the course of 1 year. They will be evaluated for adverse events, as well as the effect of the drug on inflammatory lesions and biomarker expression.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 12-65 years.
  • Molecularly and cellularly confirmed LAD1 with inflammatory lesions.
  • Willing to allow storage of biological samples for future research.
  • Willing to allow genetic testing of blood samples.
  • Able to provide .
  • Participants who can get pregnant or impregnate a partner must agree to use adequate when engaging in sexual activities that can result in pregnancy. Adequate contraception must be used consistently starting at screening and lasting through the final study visit. Appropriate forms of contraception include the following:

    1. Intrauterine device or equivalent.
    2. Hormonal contraceptive (eg, consistent, timely, and continuous use of contraceptive pill, patch, ring, implant, or injection) that has reached full efficacy before dosing.
    3. A double barrier method (eg, male/female condom, cap, or diaphragm plus spermicide).
    4. Be in a stable, long-term monogamous relationship, per assessment of the principal investigator (PI), with a partner who does not pose any potential pregnancy risk, eg, has undergone a vasectomy at least 6 months before the first dose of study agent or is of the same sex as the participant.
    5. Have had a hysterectomy and/or a bilateral tubal ligation or both ovaries removed.

Exclusion criteria

EXCLUSION CRITERIA:

  • History of (except for basal cell carcinoma) within the previous 5 years.
  • Infected with .
  • Active uncontrolled bacterial, viral, or fungal infection.
  • Active or chronic viral hepatitis.
  • Active or latent untreated tuberculosis.
  • Received Bacillus Calmette-Guerin vaccine within the last year.
  • Received within 15 weeks before the first dose.
  • Allergy to any component of the ustekinumab formulation.
  • Pregnant or breastfeeding.
  • Any condition that, in the opinion of the investigator, contraindicates participation in this study.
Terms in these criteria, in plain language(5)

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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
