FLASH [Fluorescent Light Activated Synthetic Hypericin] Clinical Study: Topical SGX301 (Synthetic Hypericin) for the Treatment of Cutaneous T-Cell Lymphoma (Mycosis Fungoides)
To evaluate the use of SGX301, a topical photosensitizing agent, to treat patients with patch/plaque phase cutaneous T-cell lymphoma (mycosis fungoides).

- Primary Purpose
- Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
|Three treatment cycles, each six (6) weeks followed by a two (2) week rest period. Treatment uses 0.25% SGX301 in USP Hydrophilic Ointment (or placebo) applied twice per week followed by fluorescent light therapy. Cycle 1: Patients randomized 2:1 to active/placebo will have three (3) index lesions treated and evaluated. Cycle 2: All patients will have three (3) index lesions treated and evaluated with active SGX301 ointment. Cycle 3: All patients will be given the opportunity to enter an open-label cycle of active SGX301 ointment treatment for all lesions (index and non-index).||
|Placebo ointment is indistinguishable from ointment containing active SGX301 and is only used in Cycle 1. Treatment paradigm (ointment application and fluorescent light therapy) is identical.||
