Inclusion Criteria:

1. Patients must be able to understand and communicate with the investigator and comply with the requirements of the study and must give a written, signed and dated informed consent before any study related activity is performed.
2. Men or women, non-pregnant and non-lactating, at least 18 years of age at time of screening

3. Chronic mild to moderate plaque-type psoriasis diagnosed at least 6 months prior to baseline. Chronic mild to moderate plaque-type psoriasis as defined at screening by:

   • BSA affected by plaque-type psoriasis of less than 10%
4. Eligible for topical therapy according to current psoriasis treatment guidelines (12).

Exclusion Criteria:

1. Forms of psoriasis other than mild to moderate plaque-type (e.g., pustular, erythrodermic and guttate psoriasis)
2. Hyperpigmentation, e.g. birth marks, freckles, scar tissue at the psoriasis plaque areas that are intended to be treated
3. Intertriginous plaques or plaques on the hands, feet, neck, face, elbows, knees, or on the scalp will not be eligible as plaques for treatment.
4. Plaques on eyelids, lips or mucous membranes, open wounds, moles or birth marks, areas at risk of developing post-inflammatory hypo- or hyperpigmentation due to high levels of UV radiation subsequent to treatment will not be eligible for treatment.
5. Drug-induced psoriasis (i.e., new onset or current exacerbation from e.g. beta-blockers, or lithium)
6. Ongoing use of prohibited psoriasis treatments (e.g., topical corticosteroids, UV-therapy). Washout periods detailed in the protocol have to be adhered to (see Table 5-2)
7. Ongoing use of other non-psoriasis prohibited treatments. Washout periods detailed in the protocol have to be adhered to (see Table 5-2). All other prior non-psoriasis concomitant treatments must be on a stable dose for at least four weeks before baseline
8. Use of any other investigational drugs within 30 days prior to screening (or within 5 half-lives or until the expected PD effect has returned to baseline, whichever is longer).
9. Requiring treatment with any biological medicinal product during the study other than the study medication.
10. Any contraindication to etanercept (Enbrel®) or calcipotriol/betamethasone (Daivobet®).
11. Previous (last 12 months) and current exposure biologics, such as etanercept, adalimumab.
12. Any contraindication to treatment with the P.L.E.A.S.E® device, including Fitzpatrick skin types V or VI.
13. Current treatment or need for treatment with any prohibited medications (listed under Section 5.9.6).
14. Any serious illness or uncontrolled medical condition, including but not limited to severe infections, significant hepatic or renal disease, uncontrolled hypertension (defined as blood pressure ≥160/95), congestive heart failure (NYHA class III or IV), or other severe, uncontrolled cardiac disease.
15. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test (cut-off as defined by laboratory)
16. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, UNLESS they agree to use highly effective methods of contraception (defined in Section 6.5.7) during the study and for 12 months after stopping treatment. Women are considered not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
17. Active ongoing inflammatory diseases other than psoriasis that might confound the evaluation of the benefit of treatment with etanercept
18. Underlying condition (including, but not limited to metabolic, hematologic, renal, hepatic, pulmonary, neurologic, endocrine, cardiac, infectious or gastrointestinal) which in the opinion of the investigator significantly immunocompromises the patient and/or places the patient at unacceptable risk for receiving an immunomodulatory therapy
19. History of clinically significant liver disease or liver injury as indicated by abnormal liver function tests. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) or alkaline phosphatase may not exceed 2.5 x upper limit of normal at screening.
20. Pre-existing or recent-onset central or peripheral nervous system demyelinating disorders according to investigator's discretion and where necessary taking into account a neurological assessment; patients who are considered to have an increased risk of developing a demyelinating disease
21. Significant cardiovascular problems, including but not limited to the following: uncontrolled hypertension (blood pressure ≥160 systolic/95 diastolic mmHg), congestive heart failure with known decreased left ventricular ejection fraction
22. Patients with a serum creatinine level exceeding 176.8 μmol/L (2.0 mg/dL)
23. Any of the following laboratory values at screening: total WBC count <3,500/μL, or neutrophils <2,000/μL or platelets <125,000/μL or hemoglobin <10.0 g/dL
24. Positive serology to hepatitis C infection (i.e. positive antibody against Hepatitis C virus) or hepatitis B infection (i.e. positive hepatitis B surface antigen [HBsAg]).
25. Severely immunocompromised state, including but not limited to Felty's syndrome and known human immunodeficiency virus (HIV) infection
26. Active tuberculosis. If a QuantiFERON®- Tuberculosis (TB) Gold test at screening is positive, further work-up, according to local guidelines/practices needs to be performed to conclusively establish that that the patient has no evidence of active tuberculosis.
27. History of serious recurrent, chronic infectious disease (excluding fungal infections of the nail beds) or active systemic infections during the last two weeks (exception: common cold) prior to baseline and any infections that reoccur on a regular basis; patients with a history or evidence of opportunistic infections including specific pathogens such as listeria, legionella and parasitic infections. Investigator discretion should be used regarding patients who have traveled or resided in areas of endemic mycoses, such as histoplasmosis, coccidioidomycosis or blastomycosis and for patients with underlying conditions that may predispose them to infection, such as advanced or poorly controlled diabetes
28. Known infection with human immunodeficiency virus (HIV), hepatitis B or hepatitis C at screening or baseline
29. History of lymphoproliferative disease or any known malignancy or history of malignancy of any organ system (except for basal cell carcinoma or actinic keratoses that have been treated with no evidence of recurrence in the past 3 months, and except for carcinoma in situ of the cervix or non-invasive malignant colon polyps that have been removed)
30. Current severe progressive or uncontrolled disease which in the judgment of the clinical investigator renders the patient unsuitable for the trial
31. Inability or unwillingness to undergo repeated venipuncture (poor tolerability or lack of access to veins)
32. Blood donation or blood loss of >400 ml in the 8 weeks prior to randomization.
33. History of hypersensitivity to any recombinant protein drugs or any of the excipients used in Enbrel® (see list of excipients in Table 5-1)
34. Patients who are allergic to rubber or latex (the needle cover on the prefilled syringes for Enbrel® contain dry natural rubber)
35. Any medical or psychiatric condition which, in the Investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol
36. History or evidence of ongoing alcohol or drug abuse, within the last six months before baseline
37. Plans for administration of live vaccines during the study period or live vaccination within 6 weeks prior to baseline
38. Patients not willing to limit UV light exposure (e.g., sunbathing and/or the use of tanning devices) during the course of the study.
