Full Title of Study: “A Randomized, Double-Blind, Vehicle-Controlled, Multicenter, Parallel Group Study of the Efficacy and Safety of DFD-06 Cream in the Treatment of Moderate to Severe Plaque Psoriasis for 14 Days”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment

- Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
- Study Primary Completion Date: July 2016
This study will be a multicenter (approximately 30 sites), randomized, vehicle-controlled, double-blind, and parallel group design. Approximately 264 subjects with moderate to severe plaque psoriasis will be randomized to treatment with DFD-06 Cream or Vehicle Cream. Subjects will use study product twice daily for 14 days. Subject visits are scheduled at Screening, Baseline (Day 1) and Days 4, 8, and 15. Clinical determinations of disease severity will be performed using the total sign score (TSS) for the target lesion and Investigator Global Assessment (IGA) for overall severity.
- Drug: DFD06-Cream
- Twice daily topical application for 14 days.
- Drug: Vehicle Cream
- Twice daily topical application for 14 days.
Arms, Groups and Cohorts
- Experimental: DFD-06 cream
- DFD-06 Cream will be applied to subjects with moderate plaque psoriasis twice daily for 14 days.
- Placebo Comparator: Vehicle Cream
- Vehicle Cream will be applied to subjects with moderate plaque psoriasis twice daily for 14 days.
Clinical Trial Outcome Measures
- Efficacy (Percentage of Subjects With Treatment Success)
- Time Frame: Day 15 Visit
- The primary efficacy endpoint is the percentage of subjects with treatment success (defined as IGA = 0 or 1 and at least a 2 grade reduction from Baseline) at the Day 15 visit. The primary analysis was done with multiple imputations. Results are combined analyses from 5 imputed data sets.
- The Percent Change in Body Surface Area of Psoriasis
- Time Frame: From Baseline to Day 15
- The percent change from baseline in Body Surface Area at Day 15. The analysis was done with multiple imputations. Results are combined analyses from 5 imputed data sets.
- The Percentage of Subjects With Treatment Success at the Day 8 Visit.
- Time Frame: At Day 8 Visit
- The percentage of subjects with treatment success (defined as IGA = 0 or 1 and at least a 2 grade reduction from Baseline) at Day 8. The analysis was done with multiple imputations. Results are combined analyses from 5 imputed data sets.
Participating in This Clinical Trial
1. Subject understands the study procedures and agrees to participate by giving written informed consent. Subjects must be willing to authorize use and disclosure of protected health information collected for the study. 2. Subject must be at least 18 years of age. 3. Subject must present with a clinical diagnosis of stable (at least 3 months) plaque-type psoriasis. 4. Subject with psoriasis involving 3% or greater BSA, not including the face, scalp, groin, axillae and other intertriginous areas. 5. Subject must have an IGA grade of 3 or 4 (moderate to severe) at the Baseline Visit. 6. Female subjects of childbearing potential must agree to use contraception during the study which can include abstinence with an adequate secondary option should the subject become sexually active. All women of childbearing potential must complete a urine pregnancy test (test must have a sensitivity of at least 25mIU/ml for human chorionic gonadotropin) at the Baseline Visit (Visit 2) and the test result must be negative to be eligible for enrollment. 7. Subject must be in good general health as determined by the investigator and supported by the medical history and normal or not clinically significant abnormal vital signs (blood pressure and pulse). Exclusion Criteria:
1. Current diagnosis of unstable forms of psoriasis including guttate, erythrodermic, exfoliative or pustular psoriasis. 2. Other inflammatory skin disease that may confound the evaluation of the plaque psoriasis (e.g., atopic dermatitis, contact dermatitis, tinea corporis). 3. Presence of pigmentation, extensive scarring, or pigmented lesions or sunburn which could interfere with the rating of efficacy parameters. 4. History of psoriasis unresponsive to biological or topical treatments. 5. History of organ transplant requiring immunosuppression, HIV, or other immunocompromised state. 6. Use within 180 days prior to Baseline Visit of biologic treatment for psoriasis (e.g., infliximab, adalimumab, etanercept, ustekinumab, secukinumab, or alefacept). 7. Have received treatment for any type of cancer within 5 years of the Baseline Visit except skin cancer and cervical cancer (in situ) are allowed if at least 1 year before the Baseline Visit. 8. Use within 60 days prior to the Baseline Visit of: 1) systemic or topical immunosuppressive drugs (e.g., tacrolimus, pimecrolimus), 2) systemic antipsoriatic treatment (e.g., methotrexate, cyclosporine, hydroxyurea) or 3) oral retinoids (e.g., acitretin, isotretinoin). 9. Use within 30 days prior to the Baseline Visit of: 1) systemic steroids, 2) PUVA therapy, 3) systemic anti-inflammatory agents (e.g., mycophenolate mofetil, sulfasalazine, 6-thioguanine), or 4) UVB therapy. Inhaled, intraocular, and intranasal steroids are allowed. 10. Use within 14 days prior to the Baseline Visit of: 1) topical antipsoriatic drugs (e.g., salicylic acid, anthralin, coal tar, calcipotriene), 2) topical retinoids (e.g., tazarotene, tretinoin) or 3) topical corticosteroids. 11. Subjects who have participated in a study of an investigational drug 60 days prior to the Baseline Visit.
