- Primary Outcome Measures
Name Time Method Maximum Tolerated Dose (MTD) as Determined by the Number of Participants With Dose Limiting Toxicities Day 1 to day 28 Number of patients with Dose Limiting Toxicities (DLT). A DLT is an adverse event that determined the treatment dose level was not tolerable for that patient in Cycle 1.
- Secondary Outcome Measures
Name Time Method Number of Participants Who Responded to Treatment Every 28 days for up to 6 Months of Treatment Disease burden as assessed by the pre-specified Severity Weighted Assessment Tool (SWAT) measurement. A Response is defined as equal to or greater than 50% improvement in SWAT score.
SWAT Score is determined by the Lesions classified as patch, plaque, or tumor. The sum of percent of total body surface area (%TBSA) by lesion type is derived and multiplied by a factor of 1 (for patch), 2 (for plaque), or 4 (for tumor). The skin score total is derived by summing the skin score subtotals for patches, plaques and tumors. The skin score total is dimensionless and can range from 0 to 400
