A Confirmatory Phase 3 Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of the Efficacy of Topical HyBryte™ (Hypericin Sodium) and Visible-Light Activation for the Treatment of Cutaneous T-Cell Lymphoma (CTCL)


Description

To evaluate the use of HyBryte, a topical photosensitizing agent, to treat patients with patch/plaque phase cutaneous T-cell lymphoma (mycosis fungoides).The primary objective of this Phase 3 study is to evaluate the ability of an 18-week course of HyBryte and visible light to induce a Treatment Response in patients with patch/plaque phase CTCL compared to patients receiving placebo and visible light.The study will evaluate the efficacy and safety of HyBryte (0.25% hypericin) gel or placebo gel applied twice weekly for 18 weeks. Treated lesions will be covered with opaque material (such as opaque clothing), followed 21 (±3) hours later by the administration of visible light. All of the participant's lesions that are readily available for exposure to the visible light source will be treated and 3 to 5 index lesions in each patient will be prospectively identified and documented for modified Composite Assessment of Index Lesion Severity (mCAILS) evaluation. Participants will be followed

Trial Eligibility

Inclusion Criteria: * Patients must have a clinical diagnosis of cutaneous T-cell lymphoma (CTCL), Stage IA, Stage IB, or Stage IIA. * Patients with a minimum of three (3) evaluable, discrete lesions. * Patients willing to follow the clinical protocol and voluntarily give their written informed consent. * Female patients not pregnant or nursing and willing to undergo a pregnancy test within 30 days prior to treatment initiation. Exclusion Criteria: * History of sun hypersensitivity and photosensitive dermatoses including porphyria, systemic lupus erythematosus, Sjögren's syndrome, xeroderma pigmentosum, polymorphous light eruptions, or radiation therapy within 30 days of enrolling. * History of allergy or hypersensitivity to any of the components of HyBryte. * A Screening ECG with a QT interval \>470 ms (corrected for heart rate using the Fridericia's formula). * All women of childbearing potential (WOCBP) and males with female partners who are WOCBP not willing to use effective contraception. * Patients receiving topical steroids or other topical treatments (eg, nitrogen mustard) on treated lesions for CTCL within 2 weeks of enrollment. * Patients receiving systemic steroids, psoralen UVA radiation therapy (PUVA), narrow band UVB light therapy (NB-UVB) or carmustine (BCNU) or other systemic therapies for CTCL within 4 weeks of enrollment. * Patients who have received electron beam irradiation within 3 months of enrollment. * Patients with a history of significant systemic immunosuppression. * Patients taking other investigational drugs or drugs of abuse within 30 days of entry into this study. * Patients whose condition is spontaneously improving. * Patients with tumor stage or erythrodermic CTCL (stages IIB-IV). * Patients with extensive skin disease (\>30% body surface area) who would be, in the judgement of the Principal Investigator, candidates for systemic treatment. * Patient has any condition that, in the judgment of the PI, is likely to interfere with participation in the study. * Prior participation in the current study.
