Safety, Pharmacodynamics (PD), Pharmacokinetics (PK) Study of SHP141 in 1A, 1B, or 2A Cutaneous T-Cell Lymphoma (CTCL)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to investigate the safety and tolerability of topical SHP141 applied directly to skin lesions in patients with Stage IA, IB, or IIA Cutaneous T-cell Lymphoma. This study will also investigate the effect of SHP141 on skin lesions in patients with Stage IA, IB, or IIA CTCL.

Eligibility Criteria
-----------------
Inclusion Criteria: Histopathologically confirmed CTCL; a documented verifiable biopsy report is required. Documented clinical Stage IA, IB, or IIA CTCL. Skin lesion involvement of at least 3% of BSA accessible for topical application of study drug and biopsy. ECOG performance status of 0-2. Exclusion Criteria: CTCL with histologic evidence of folliculotropic variant or large cell transformed CTCL. Severe pruritus requiring systemic or topical treatment. Palpable lymph node ≥1.5 cm in diameter (unless the lymph node has been biopsied and has been designated as Stage IA-IIA disease).

Any prior history of a hematologic malignancy (other than CTCL). History of or current major renal, hepatic, gastrointestinal, pulmonary, cardiovascular, genito-urinary or hematological disease, CNS disorders, infectious disease or coagulation disorders as determined by the Investigator. Evidence of active Hepatitis B or C or HIV. Circulating atypical cells >5%

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients With Complete or Partial Response as Measured by Change in Lesion Severity Using CAILS (Composite Assessment of Index Lesion Severity) | Response assessed by change in lesion severity using Composite Assessment of Index Lesion Severity (CAILS) Assessment Tool which measures clinical signs of CTCL by erythema; scaling; plaque elevation; hypo- or hyperpigmentation, each on a scale of 0-8; and lesion size (cm2), on a scale of 0 (no lesion; 0 cm2) to 18 (300 cm2). Up to five index lesions are each scored, and a subtotal CAILS score is provided for each index lesion. A total score is calculated by summing these subtotals. Response criteria measure the change in CAILS score from baseline to follow-up as follows: Complete Response (CR): 100% decrease in CAILS score; Partial Response (PR): 50% - 99% decrease in CAILS score; Stable Disease (SD): < 25% increase to < 50% decrease in CAILS score; Progressive Disease (PD) ≥ 25% increase in CAILS score. | Weekly through day 28 (days 1, 7, 14, 21, 28) and again day 42 |
