This study will evaluate the anti-pruritic effect of apremilast in patients with known PN.
Prurigo nodularis(PN) is a chronic skin disease, characterized by severe pruritus, multiple hyperkeratotic nodules and papules often located on the extensor part of the upper and lower extremities with a symmetrical distribution. The disease often appears between 20-60 years of age affecting men and women equally.
The pathogenesis of PN is poorly understood and it is unknown whether PN is a primary dermatological disease or if it arises secondary to intense pruritus and scratching of the skin with other diseases being the cause of the itching.
A number of studies have investigated if certain biochemical parameters are involved in mediating PN e.g. studies have indicated that the small nerve fibres in dermis in lesioned skin have an increased density of Substance P (neuropeptide and a well-known mediator of pruritus. when compared to non-lesioned skin.Other studies have suggested that patients with PN have a high presence of nerve growth factor (NGF) in dermis leading to modulation of the small nerve fibres, as well as an increased number of eosinophilic granulocytes, mast- and Merkel cells. Additionally, studies have found increased levels of IL-6 and IL-31 in blood in patient with PN. However the pathogenesis of PN remains unknown.
Among patients with atopic dermatitis there is a higher frequency of patients with PN as well as PN seem to be associated with certain liver- and kidney diseases. Anxiety and depression are also more common in patients with PN.
Patients with PN suffer from impaired quality of life due to ongoing pruritus and skin lesions(5). PN is mainly treated with topical steroids, UVB, PUVA or thalidomide, although none of these treatments seem to be able to control the disease and furthermore a number of these treatments are associated with several side effects.
As the phosphodiesterase 4 (PDE4)-inhibitor (apremilast) have shown a , it is speculated that apremilast may have an effect in patients with PN. Lack of effective treatments for PN supports further development for treatment options.
This study will evaluate the anti-pruritic effect of apremilast in patients with known PN. This interventional study, will be performed at the Department of Dermatology and Allergy at Herlev and Gentofte Hospital (Gentofte site), University of Copenhagen, Hellerup, Denmark.

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.
Exclusion Criteria:
Women of must use effective which includes IUD, oral, injected or implanted hormonal device, hormone patch, vaginal hormonal ring og sterilization.
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.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
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.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
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.
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.
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).
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.
Corticosteroids (steroids)
