Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Responders and Non-Responders With a Treatment Response in 3 Treated Lesions as Defined as a =50% Improvement in the Composite Assessment of Index Lesion Disease Severity (CAILS) Score When Compared to Patients Receiving Placebo	The percentage of patients achieving a treatment response in each of the 2 treatment groups. A treatment response was defined as a =50% improvement in CAILS score at Week 8 when compared to the CAILS score at baseline.; The Composite Assessment of Index Lesion Disease Severity (CAILS) score measures: Erythema (or redness) on a scale of 0 (no redness) to 8 (very red), Scaling on a scale of 0 (no scaling) to 8 (all of the lesion is covered by a very rough surface), Plaque Elevation on a scale of 0 (no evidence of plaque above normal skin level) to 3 (plaque shows marked elevation above normal skin level) and Surface Area on a scale of 0 (no lesion/surface area is 0 cm^2) to 18 (the lesion is larger than 300 cm^2). A lower score means a better outcome.; The overall CAILS score was calculated by adding the total score as described above for each of the 3 lesions. The overall CAILS score has a range of 0 to 111. A lower score means a better outcome.	8 weeks
Secondary	Number of Responders and Non-Responders With a Treatment Response in 3 Treated Lesions as Measured by the Composite Assessment of Index Lesion Disease Severity (CAILS) Score (Cycle 1 and 2 SGX301 vs Cycle 1 Placebo)	The percentage of patients achieving a treatment response at Week 16 that received SGX301 for both Cycle 1 and 2 compared to the response rate in patients that received Placebo in Cycle 1.; The Composite Assessment of Index Lesion Disease Severity (CAILS) score was measured as previously described.	16 weeks
Secondary	Number of Responders and Non-Responders With a Treatment Response of 3 Treated Lesions as Measured by the Composite Assessment of Index Lesion Disease Severity (CAILS) Score in Patients Who Received 3 Cycles of SGX301	The percentage of patients achieving a treatment response at Week 24 compared at Week 16 in SGX301 treatment group. A treatment response was defined as a =50% improvement in CAILS score when compared to the CAILS score at baseline.; The Composite Assessment of Index Lesion Disease Severity (CAILS) score was measured as previously described.	24 weeks
Secondary	Patch Lesion Response Rates With Extended Treatment (Cycle 1 & 2 SGX301 vs Cycle 1 Placebo)	The proportion of patch lesions achieving a treatment response at Week 16 in the SGX301 treatment group compared to Week 8 in the Placebo treatment group. A treatment response was defined as a =50% improvement in CAILS score when compared to the CAILS score at baseline for individual lesions.; The Composite Assessment of Index Lesion Disease Severity (CAILS) score was measured as previously described.	16 weeks
Secondary	Plaque Lesion Response Rates With Extended Treatment (Cycle 1 & 2 SGX301 vs Cycle 1 Placebo)	The proportion of plaque lesions achieving a treatment response at Week 16 in the SGX301 treatment group compared to Week 8 in the Placebo treatment group. A treatment response was defined as a =50% improvement in CAILS score when compared to the CAILS score at baseline for individual lesions.; The Composite Assessment of Index Lesion Disease Severity (CAILS) score was measured as previously described.	16 weeks
