Inclusion Criteria: * A clinical diagnosis of cutaneous T-cell lymphoma (CTCL, mycosis fungoides), Stage IB or Stage IIA * CTCL lesions covering ≥ 10% of their body surface area Exclusion Criteria: * History of allergy or hypersensitivity to any of the components of HyBryte * Pregnancy or mothers who are breast-feeding * Males and females not willing to use effective contraception * Subjects with history of sun hypersensitivity or photosensitive dermatoses (e.g., porphyria, systemic lupus erythematosus (SLE), Sjogren's syndrome, etc.) * Subjects whose condition is spontaneously improving * Subjects receiving topical steroids or other topical treatments (e.g., nitrogen mustard) on index lesions for CTCL within 2 weeks of enrollment * Subjects receiving systemic steroids, psoralen ultraviolet A (UVA) radiation therapy (PUVA), narrow band ultraviolet B (UVB) light therapy (NB-UVB) or carmustine (BCNU) or other systemic therapies for CTCL within 3 weeks of enrollment * Subjects who have received electron beam irradiation within 3 months of enrollment * Subjects with a history of significant systemic immunosuppression * Subjects taking other investigational drugs or drugs of abuse within 30 days of enrollment * Subjects receiving drugs known to cause photosensitization within 2 weeks of starting HyBryte therapy unless they have not had evidence of photosensitization after receiving a stable dose of the medication for a minimum of 4 weeks

Outcomes

Primary Outcomes

Electrocardiograms (ECG)

Assess any ECG QT interval changes (defined as any occurrences of QT interval \>500 ms or changes in QT interval \>60 ms) during standard HyBryte photodynamic therapy.

Time frame: 10 weeks

Systemic Blood Levels

Assess the systemic blood levels of hypericin during standard HyBryte photodynamic therapy.

Time frame: 10 weeks

Secondary Outcomes

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.

A treatment response was defined as a ≥50% improvement in CAILS score at Week 10 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.

Time frame: 10 weeks

Number of Index Lesions With a Treatment Response as Defined as a ≥50% Improvement in the Composite Assessment of Index Lesion Disease Severity (CAILS) Score.

A treatment response was defined as a ≥50% improvement in CAILS score at Week 10 when compared to the CAILS score at baseline in each of the individual Index Lesions. 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.
