What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pruritus by VAS (Visual Analogue Scale)

    At end of treatment (Day 28) participants assessed the intensity of present pruritus of each treated area on a visual analogue scale (VAS) with a score of "0" (no itch at all) to "10" (worst imaginable itch) at the two extremes on a 100 mm line.

    Measured: At end of treatment (Day 28)

Secondary outcomes (15)
  1. Pruritus by VAS (Visual Analogue Scale)

    At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42, participants assessed the intensity of present pruritus of each treated area on a visual analogue scale (VAS) with a score of "0" (no itch at all) to "10" (worst imaginable itch) at the two extremes on a 100 mm line.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28), and Day 42

  2. Change From Baseline in Participants' Global Assessment on Treatment Areas

    At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42, participants assessed their prurigo on each treated area using the following score: 0 = no symptoms, 1 = mild, 2 = moderate, 3 = severe. The change was calculated as the value at the later time point minus the value at baseline. The change at Day 1 was therefore 0 and negative values represent a decrease in score.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  3. Clinical Score Assessment of Crusting

    The (sub)investigator assessed the clinical picture at each treated area at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 using the following score:

    Criteria:

    Crusts

    Evaluation:

    0 = not existing

    1. = mild
    2. = moderate
    3. = severe

    The score will be an integer on the scale 0-3.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  4. Clinical Score Assessment of Erythema

    The (sub)investigator will assess the clinical picture at each treated area at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 using the following score:

    Criteria:

    Erythema

    Evaluation:

    0 = not existing

    1. = mild
    2. = moderate
    3. = severe

    The score will be an integer on the scale 0-3.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  5. Clinical Score Assessment of Scratch Artefacts

    The (sub)investigator will assess the clinical picture at each treated area at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 using the following score:

    Criteria:

    Scratch artefacts: Superficial damage to the skin caused by severe scratching.

    Evaluation:

    0 = not existing

    1. = mild
    2. = moderate
    3. = severe

    The score will be an integer on the scale 0-3.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  6. Clinical Score Assessment of Infiltration

    The (sub)investigator will assess the clinical picture at each treated area at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 using the following score:

    Criteria:

    Infiltration

    Evaluation:

    0 = not existing

    1. = mild
    2. = moderate
    3. = severe

    The score will be an integer on the scale 0-3.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  7. Transepidermal Water Loss (TEWL)

    The (sub)investigator will made the following clinical assessment:

    Transepidermal water loss was defined as amount of released water from skin surface in g/cm^2 per hour. The TEWL is increased in case of damage of skin barrier.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  8. Lesional Erythema by Mexameter

    The skin colour of the participants was evaluated by use of a Mexameter spectrophotometer. The instrument computed an erythema index (with a range between 0 and 999, where higher values indicate more erythema or redness) which may be used as an indication of skin properties.

    Mexameter measurements were performed at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 to assess stimulation of microcirculation, irritating effects, and occurring erythema.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  9. Non-lesional Erythema by Mexameter

    The skin colour of the participants was evaluated by use of a Mexameter spectrophotometer. The instrument computed an erythema index (with a range between 0 and 999, where higher values indicate more erythema or redness) which may be used as an indication of skin properties.

    Mexameter measurements were performed at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 to assess stimulation of microcirculation, irritating effects, and occurring erythema.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  10. Melanin by Mexameter

    The skin colour of the participants was evaluated by use of a Mexameter spectrophotometer. The instrument computed a melanin index (with a range between 0 and 999, where higher values indicate more melanin) which may be used as an indication of skin properties.

    Mexameter measurements were performed at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 to assess stimulation of microcirculation, irritating effects, and occurring erythema.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  11. Non-lesional Melanin by Mexameter

    The skin colour of the participants was evaluated by use of a Mexameter spectrophotometer. The instrument computed a melanin index (with a range between 0 and 999, where higher values indicate more melanin) which may be used as an indication of skin properties.

    Mexameter measurements were performed at baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42 to assess stimulation of microcirculation, irritating effects, and occurring erythema.

    Measured: At baseline (Day 1), Day 14, end of treatment (Day 28) and Day 42

  12. Daily Assessments of Duration of Pruritus (Preceding 12 Hours)

    During the trial participants completed a diary twice daily, in the morning and in the evening, each covering the preceding 12 hours, which collected the number of hours with pruritus within the last 12 hours on both areas by use of a 7-point scale (<0.5 hours, 0.5-1 hours, 1-2 hours, 3-4 hours, 5-6 hours, 7-8 hours, 9-12 hours).

    Duration of pruritus was categorized as follows: 1 if <0.5 hours, 2 if 0.5-1 hours, 3 if 1-2 hours, 4 if 3-4 hours, 5 if 5-6 hours, 6 if 7-8 hours and 7 if 9-12 hours.

    The evening baseline measure was taken on the evening of Day -1 and the morning baseline measure was taken on the morning of Day 1 before cream was applied.

    Measured: From baseline to Day 31

  13. Daily Assessments of Average Pruritus by Use of a VAS

    During the trial participants completed a diary twice daily, in the morning and in the evening, each covering the preceding 12 hours, which collected the average intensity of pruritus since last evaluation by use of a VAS (ranging from 0 to 100). The participants assessed the intensity of present pruritus of each treated area on a visual analogue scale (VAS) with a score of "0" (no itch at all) to "10" (worst imaginable itch) at the two extremes on a 100 mm line.

    The evening baseline measure was taken on the evening of Day -1 and the morning baseline measure was taken on the morning of Day 1, before cream was applied.

    Measured: From baseline to Day 31

  14. Daily Assessments of Maximum Intensity of Pruritus by Use of a VAS

    During the trial participants completed a diary twice daily, in the morning and in the evening, each covering the preceding 12 hours, which collected the maximum intensity of pruritus since last evaluation by use of a VAS (ranging from 0 to 100). The participants assessed the intensity of present pruritus of each treated area on a visual analogue scale (VAS) with a score of "0" (no itch at all) to "10" (worst imaginable itch) at the two extremes on a 100 mm line.

    The evening baseline measure was taken on the evening of Day -1 and the morning baseline measure was taken on the morning of Day 1 before cream was applied.

    Measured: From baseline to Day 31

  15. Percent Change From Baseline in Pruritis Assessed by VAS at End of Treatment

    On the last day of treatment, participants assessed the change of pruritus compared to baseline in percentage by use of a VAS (ranging from 0 to 100). The participants assessed the intensity of present pruritus of each treated area on a visual analogue scale (VAS) with a score of "0" (no itch at all) to "10" (worst imaginable itch) at the two extremes on a 100 mm line.

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Aprepitant in people with Pruritus, run by LEO Pharma at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Jul 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pruritus by VAS (Visual Analogue Scale) (time frame: At end of treatment (Day 28)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2025.
