About

This study seeks to show whether there is a benefit of prescribing Enstilar in the treatment of patients with moderate plaque type psoriasis. Subjects will receive study treatment of Enstilar foam.

Full description

Approximately 20 subjects from 3 sites will be enrolled in this open-label study. Subjects will receive Enstilar foam and all adverse events and concomitant medications will be recorded.

Subjects will attend a screening visit/baseline visit and those with plaque-type psoriasis and bilateral symmetric psoriatic plaques will have a target lesion identified on knees or elbows and subjects will receive study treatment as outlined above.

Enstilar will be initiated daily for the entire study period of four weeks. Study visits will occur as follows: screening/baseline, week 2, week 4. Study assessments at each visit will be Body Surface Area (BSA,) Physicians Global Assessment (PGA,) Target lesion size, Total Lesion Severity Score (TLSS) and standard medical assessments. There will be standard medication/treatment and washout periods.

NOTE: The original study protocol dated december 20, 2017, was designed to compare the effect of Enstilar versus vehicle for the treatment of plaque psoriasis at a 1:1 ratio. A protocol amendment on March 20, 2018 eliminated the chance of placebo and made this an open-label study of the effects of Enstilar for the treatment of plaque psoriasis.

Enrollment: 20 patients

Sex: All

Ages: 18+ years old

   Reliable methods of contraception are:

   • hormonal methods or intrauterine device (IUD) in use > 90 days prior to study drug administration, barrier methods plus spermicide in use > 14 days prior, or vasectomized partner.

   [Exception: Female subjects of child bearing potential (CBP) who are not sexually active are not required to practice a reliable method of contraception and may be enrolled at the Investigator's discretion provided they are counselled to remain sexually inactive for the duration of the study and understand the risks involved in getting pregnant during the study.]

2. Moderate plaque type psoriasis eligible for topical therapies.

3. Patients with a minimum of 3% BSA to a maximum of 20% BSA & bilateral symmetric psoriatic plaques of 2 to 4 cm in diameter.

4. Physician Global Assessment (PGA) score of 3.

5. Able to understand study requirements and sign Informed Consent/HIPAA forms.

Exclusion criteria

1. Female subjects who are pregnant, breast-feeding, or who are of childbearing potential and not practicing a reliable method of birth control, or male subjects planning a pregnancy with their spouse or partner while in the study.

3. Patients with guttate, erythrodermic, or pustular psoriasis
4. Serious skin condition (other than psoriasis) or uncontrolled medical condition (in the opinion of the investigator.)
5. Topical steroids, topical immunomodulators, topical vitamin D derivatives, tar, salicylic acid, anthralin or any other topical treatment for psoriasis within 2 weeks of baseline.
6. Use of any biologics within 3 months of baseline.
7. Use of other systemic psoriasis treatments (ie, oral retinoids, methotrexate, cyclosporine, or other immunomodulators) within 4 weeks of baseline.
8. Use of ultraviolet B rays (UVB) or psoralen+ultraviolet a rays (PUVA) within 2 weeks of baseline.
9. Skin conditions (e.g. eczema) other than psoriasis that may interfere with evaluations of psoriasis.
