Trial Outcomes & Findings for Study of Total Skin Electron Beam Therapy (TSEBT) in Stage IB-IIIA Mycosis Fungoides (NCT NCT01073267)

NCT ID: NCT01073267

Last Updated: 2015-12-31

Results Overview

Objective response rate defined as the proportion of participants achieving complete clinical response (CCR) and partial response (PR) (i.e. overall response (OR)) as assessed by the modified Severity-Weighted Assessment Tool (mSWAT). Clinical response (according to mSWAT) are documented as stable disease (SD), partial response (PR), complete clinical response (CCR), or progressive disease (PD) as defined: Complete clinical response (CCR): no evidence of cutaneous disease on exam, confirmed at 4 week time point; Partial response (PR): ≥ 50% decrease of modified SWAT score compared to baseline score, confirmed at 4 week time point; Stable disease (SD): Neither CR, PR, or PD, i.e. change from baseline is less than 50% decrease, but also less than 25% increase in mSWAT score compared to nadir score; Progressive disease (PD): ≥ 25% increase in modified SWAT score compared with nadir score.
