Study summary

In this study it will be investigated if patients with atopic dermatitis responding to EPOGAM treatment, show a significant increase of dihomo-gamma-linolic acid in the blood.

Read the detailed description

Patients with atopic dermatitis will receive EPOGAM 1000 for 12 weeks. Clinical symptoms of the disease will be assessed using the SCORAD score. Dihomo-gamma-linolic acid levels in the blood will be measured with GC-MS.

Terms in these criteria, in plain language(4)

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.

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.

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Interventions

  • One capsule of EPOGAM 1000 contains 932-1073 mg Oenothera seminis oleum, equivalent to 80 mg gamma-linolic acid. Children (2-12 years) take 2 capsules in the morning and evening, whereas persons over 12 years take 3 capsules in the morning and evening. The duration of the treatment is 12 weeks.

    Also known as: Oenothera seminis oleum, Evening Primrose Oil, EPOGAM

What researchers measure

Primary outcomes

  1. Levels of dihomo-gamma linolic acid in the blood

    Time frame: 0, 4 and 12 weeks after start of treatment

  2. Efficacy of EPOGAM 1000 treatment on the symptoms of atopic dermatitis

    Time frame: 0, 4 and 12 weeks after start of treatment

Secondary outcomes

  1. Assessment of the efficacy of EPOGAM 1000 treatment by the patient on a visual analog scale

    Time frame: 4 and 12 weeks after start of treatment

  2. Assessment of the symptoms itching, sleep disorder, skin sensation, skin condition by the patient on a visual analog scale

    Time frame: 4 and 12 weeks after start of treatment

  3. Willingness of the patient to further take the medication and assessment of problems related to the intake of the study drug.

    Time frame: 12 weeks after start of treatment

  4. Assessment of the efficacy of EPOGAM treatment by the investigator

    Time frame: 4 and 12 weeks after start of treatment

  5. Assessment of adverse events (AE)

    Time frame: During treatment (12 weeks)

  6. Physical examination

    Time frame: 0, 4 and 12 weeks after start of treatment

  7. Laboratory values (blood examination)

    Time frame: 0, 4 and 12 weeks after start of the treatment

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 Jan 26, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
