Selenium in the Treatment of Complicated Lymphatic Malformations

A Phase 1 interventional study of Selenium in Lymphatic Malformations, sponsored by Medical College of Wisconsin. Terminated at 1 site in United States. Open to participants aged 14 Years to 30 Years. Per ClinicalTrials.gov, last updated 2013-04-23.

Sponsored by Medical College of Wisconsin · Phase 1, Interventional, and Treatment

Why this study was terminated
The investigators chose to terminate the study due to participant attrition. Of the limited data evaluable, none of the patients experienced adverse events.

Study summary

The investigators propose a pilot trial to obtain preliminary information regarding the safety and response rate of patients with symptomatic lymphatic malformations treated with oral Selenium. Information obtained in this pilot trial will be used to plan future phase 2 clinical trials.

Hypotheses:

  • Selenium will be safe and efficacious in the treatment of adolescents and young adults with symptomatic lymphatic malformations
  • Disease response will correlate with serum levels of selenium and blood levels of antioxidants essential to selenium metabolism.

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

  • Patients must have clinical and radiographic features consistent with a lymphatic malformation (LM). Patients with combined venous lymphatic malformations (CVLM) will be included if the predominant componet is lymphatic based on MRI. Both macrocystic and microcystic LM will be eligible. Tissue is required to confirm the presence of an abnormal lymphatic malformation.
  • All patients diagnosed with lymphatic malformations between 14 and 30 years of age will be eligible.
  • Patients must have lymphatic malformations with potential to cause morbidity including one or more of the following: Lymphedema, Coagulopathy, Chronic Pain, Recurrent Cellulitis (> 1 episodes/year), Ulceration and/or bleeding, Impairment of organ function, Visceral and/or bone involvement, or Disfigurement.
  • Patients receiving previous systemic therapy, surgical, debulking, or sclerotherapy will be eligible eight weeks following completion of therapy if they meet all inclusion criteria.
  • All patients and/or their parents or legal guardians must sign a written . All institutional FDA requirements for human studies must be met.

Exclusion criteria

Exclusion Criteria:

  • Younger than 14 years of age or older than 30 years of age
  • Life-threatening complications related to LM
  • Patients with preexisting renal, hepatic, or thyroid disorders
  • Patients receiving a daily multivitamin supplement or other natural products that include selenium
  • Patients that have received previous selenium therapy will not be eligible
  • Women who are pregnant or breastfeeding
Terms in these criteria, in plain language(2)

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

What researchers measure

Primary outcomes

  1. Determine a preliminary rate to oral selenium in adolescents and young adults with symptomatic lymphatic malformations

    Disease will be assessed by volumetric MRI and patient quality of life assessments at 6 months of therapy and compared to pretreatment values.

    Time frame: pretreatment and at 6 months

  2. Determine the safety of oral selenium in adolescents and young adults with symptomatic lymphatic malformations

    Time frame: throughout duration of study

Secondary outcomes

  1. Correlate selenium drug levels, expression of selenoproteins and IL-20with outcome

    Whole blood will be drawn prior to therapy and at specific time intervals after initiating selenium. Serum concentrations of selenium, selenium-dependent tripeptide glutathione and IL-20 will be measured and correlated with outcome

    Time frame: throughout duration of study

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 Apr 23, 2013, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
