  • Participant was willing and able to comply with all of the time commitments and procedural requirements of the clinical study protocol, including daily diary recordings by the participant using an electronic handheld device provided for this study.

Exclusion criteria

Exclusion Criteria:

  • Body weight less than \< 30 kg.
  • Chronic pruritus resulting from another active condition other than PN, such as but not limited to scabies, lichen simplex chronicus, psoriasis, atopic dermatitis, contact dermatitis, acne, folliculitis, lichen planus, habitual picking/excoriation disorder, sporotrichosis, bullous disease, end-stage renal disease, or cholestatic liver disease (example [e.g.] primary biliary cirrhosis) or diabetes mellitus or thyroid disease that is not adequately treated, as per standard of care.
  • Unilateral lesions of prurigo (e.g., only one arm affected).

Terms in these criteria, in plain language(8)

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

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.

What researchers measure

Primary outcomes

  1. Number of Participants With an Improvement of Greater Than or Equal to (>=) 4 From Baseline in Weekly Average Peak Pruritus Numeric Rating Scale (PP NRS) at Week 16

    The Peak Pruritus NRS is a scale that was used by the participants to report the intensity of their pruritus (itch) during the last 24 hours. For maximum itch intensity: the scores were provided on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable'. Higher scores indicate worse outcome. Weekly values are calculated as the average of 7 consecutive days of data up to the target study day (excluding) and set to missing if less than 4 days of data are available. Analysis window extension was applied to both timepoints, as described in the SAP. If a participant received any rescue therapy, composite variable strategy is applied, the underlying data at/after receipt of rescue therapy is set as worst possible value, and the response is derived from underlying data value. Participants with missing results are considered as non-responders.

    Time frame: Baseline, Week 16

  2. Number of Participants With an Investigator Global Assessment (IGA) Success at Week 16

    IGA success is defined as clear (0) or almost clear (1), and a reduction from baseline of greater than or equal to 2 points at week 16. Full scale is scored from 0-4, higher score indicates more severe symptoms. If a participant received any rescue therapy, composite variable strategy is applied, the underlying data at/after receipt of rescue therapy is set as worst possible value, and the response is derived from underlying data value. Participants with missing results are considered as non-responders.

    Time frame: Baseline, Week 16

Secondary outcomes

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Adverse Events of Special Interest (AESIs), and Serious Adverse Events (SAEs)

    AE was defined as any untoward medical occurrence in a clinical study participant administered a medicinal product which does not necessarily have a causal relationship with this treatment. TEAEs were defined as AEs occurring after the first administration of the study drug until the last study visit. SAE was any untoward medical occurrence, in the view of either the Investigator or Sponsor, that resulted in death, was life-threatening, resulted in inpatient hospitalisation or prolongation of existing hospitalisation, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was an important medical event. AESI was a noteworthy TEAE for the study drug that was to be monitored closely and reported promptly. Relatedness to study drug was based on Investigator's discretion. Analysis was performed on safety population which included all randomised participants who received at least 1 administration of study drug.

    Time frame: From Baseline up to end of treatment period (24 weeks)

  2. Number of Participants With an Improvement of >= 4 From Baseline in Weekly Average PP NRS at Week 4

For maximum itch intensity: the scores were provided on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable'. Higher scores indicate worse outcome. Weekly values are calculated as average of 7 consecutive days data up to the target study day (excluding) and set to missing, if less than 4 days data are available. Analysis window extension was applied to baseline, as described in the SAP. If a participant received any rescue therapy, composite variable strategy is applied, the underlying data at/after receipt of rescue therapy is set as worst possible value, and the response is derived from underlying data value. Participants with missing results are considered as non-responders.

    Time frame: Baseline, Week 4

  3. Number of Participants With PP NRS < 2 at Week 16

    The Peak Pruritus NRS is a scale that was used by the participants to report the intensity of their pruritus (itch) during the last 24 hours. For maximum itch intensity: the scores were provided on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'worst itch imaginable'. Higher scores indicate worse outcome. Weekly values are calculated as average of 7 consecutive days data up to the target study day (excluding) and set to missing, if less than 4 days data are available. Analysis window extension was applied to week 16, as described in the SAP. If a participant received any rescue therapy, composite variable strategy is applied, the underlying data at/after receipt of rescue therapy is set as worst possible value, and the response is derived from underlying data value. Participants with missing results are considered as non-responders.

    Time frame: Week 16

  4. Number of Participants With an Improvement of >=4 From Baseline in Sleep Disturbance Numeric Rating Scale (SD NRS) at Week 16

    The SD NRS is a scale to report the degree of participant sleep loss related to PN. The baseline SD NRS was determined based on the average of daily SD NRS (score ranging from 0 to 10) during the 7 days up to the treatment start (including until treatment start time). A minimum of 4 daily scores out of the 7 days up to baseline study day is required for this calculation. On a scale of 0 to 10, with 0 being 'no sleep loss related to the symptoms of my skin disease (prurigo nodularis)' and 10 being 'I did not sleep at all due to the symptoms of prurigo nodularis'. Higher scores indicate worse outcome. Analysis window extension was applied to both timepoints, as described in the SAP. If a participant received any rescue therapy, composite variable strategy is applied, the underlying data at/after receipt of rescue therapy is set as worst possible value, and the response is derived from underlying data value. Participants with missing results are considered as non-responders.

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 Jul 10, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
