Brief Summary

The purpose of this study is to assess the safety, tolerability and clinical activity of the SHP-141C topical cream formulations in patients with plaque type psoriasis.

Detailed Description

Psoriasis is a chronic, relapsing immunoinflammatory disorder. Chronic plaque psoriasis is the most common (85% - 90%) type. Cutaneous features of individual plaques include circular with centrifugal expansion, induration with sharp demarcation from surrounding skin, erythema and hyperkeratosis. Psoriasis has a negative impact on physical and mental aspects of life that is similar to other major chronic conditions. The modalities of psoriasis treatments can be divided into four main categories: topical, phototherapy, systemic drug therapies and systemic biological treatments. The currently available treatments for psoriasis result in either disease suppression or disease remission.There are many treatment options for the management of psoriasis using topical modalities; however all are lacking with respect to patient satisfaction and durability of treatment. Most current topical treatments, and many treatments in development, are based on modifications of a steroid structure or on Vitamin D. Recent research has identified a broad role for histone deacetylase (HDAC) proteins in numerous signaling pathways critical to cancer cell survival, such as epigenetic inheritance, gene regulation, mitosis,signal transduction and importantly, inflammation. Theoretically modulation of HDAC could lead to clinical benefit in inflammatory diseases.

2. psoriasis of at least one year.

3. Stable disease for at least two weeks prior to the commencement of study treatment.

4. One nominated target lesions must have areas of at least 86 x 57 mm2.

5. BMI of less than 35 kg/m2. -

Exclusion Criteria

1. Dermatological Conditions

• Subjects with erythrodermic, guttate, palmar, plantar or generalised pustular forms of psoriasis.
• Subjects with scalp, palmar or plantar psoriasis only.
• Subjects with any skin condition other than psoriasis, in particular eczema, cutaneous infections, significant sun damage or an inherited skin disorder (other than psoriasis).

• A history of moderate or severe asthma during the last 10 years.
• Major chronic inflammatory disease .
• Congenital immunodeficiency or cancer prone syndrome.
• History of abnormal bleeding tendencies or thrombophlebitis, or a history of Hepatitis B, Hepatitis C or HIV infection.
• History of malignancy (other than adequately treated skin carcinoma or carcinoma-in-situ of the cervix).

3. Laboratory Status

• Any evidence of organ dysfunction, which is confirmed on re-examination to be clinically significant (i.e. in the opinion of the Medical Officer would jeopardise the safety of the subject or impact on the validity of the study results),
• A creatinine clearance of less than 75 mL/min.

• Phototherapy or photochemotherapy.
• High potency topical corticosteroids.
• "Alternative medicine" treatments for psoriasis.
• Prolonged sun exposure or tanning bed use, which may in the opinion of the Investigator, modify disease activity.

• Moderate potency topical corticosteroids.
• Vitamin D analogues and topical retinoids.
• Keratolytics, coal tar and dithranol.
