Identifying Potential Patients

Presenting with skin manifestations of CTCL unresponsive to other forms of treatment1

The most common forms of CTCL are mycosis fungoides, which accounts for ~60% of cases, and Sézary syndrome, which accounts for 5% of cases.2

Mycosis fungoides is characterized by patches or plaques on the skin, which can mimic benign skin conditions (eg, eczema, dermatitis, or psoriasis).3 Early stages of mycosis fungoides are often managed with skin-directed treatments, whereas unresolved skin manifestations may require systemic treatments.4

Sézary syndrome is a leukemic variant with a generally poor prognosis. These patients typically have exfoliating skin, edema, and lichenification, with potentially severe fissuring, scaling, and itching. Patients with Sézary syndrome may also present with erythroderma (red man syndrome) and/or enlarged lymph nodes.5,6

Most patients with skin manifestations of CTCL experience slower progression of their underlying disease than patients with other forms of non-Hodgkin’s lymphoma (NHL) and should be treated accordingly.5,8

Given the chronic nature of CTCL, tolerability is an important consideration when choosing treatments.9

Real Patient Profiles

Kris, a patient treated with THERAKOS® Photopheresis

Actual photopheresis patient who has been compensated for sharing her story.

About Kris

Kris, a single mother, is working to fight the skin manifestations of CTCL.

Diagnostic history

An erythematous patch on Kris’s abdomen failed to respond to topical medications. Despite a nonspecific biopsy, her dermatologist suspected CTCL and prescribed a topical steroid. Lesions appeared intermittently for several years and then worsened to plaques with severe pruritus. A biopsy then confirmed the CTCL diagnosis.

Impact of CTCL skin manifestations

"Unbearable" pruritus reduced Kris’s quality of life. A topical cream calmed her skin symptoms during the day, allowing her to concentrate at work, but in the evenings, she scratched her skin until she bled.

About Lou

Lou, a retired Navy veteran, uses his courage to help him mentally fight the challenges of living with CTCL skin symptoms.

Diagnostic history

Onboard a US warship, 19-year-old Lou gave little thought to his "psoriasis" except to apply creams supplied by the ship’s infirmary. Twenty-five years later, with significant rash, scaling, and alopecia, the hospital biopsied him and diagnosed mycosis fungoides.

Impact of CTCL skin manifestations

Despite many treatments, Lou’s skin manifestations persisted. There were many times when Lou wanted to curl up and be a "hermit." For example, he was embarrassed by his skin flaking on friends’ furniture.

Start Patients With 2 Consecutive Days of THERAKOS® Photopheresis Every 4 Weeks1

Dosing can be adjusted based on patient response1

Initial/Standard Treatment Schedule

2 consecutive days
every 4 weeks

For a minimum of
7 cycles

If assessment during the fourth treatment cycle reveals a skin score that has worsened from baseline, the accelerated treatment schedule can be used.

Accelerated Treatment Schedule

2 consecutive days
every 2 weeks

For a maximum of
20 cycles

Patients should remain on continuous treatment for a minimum of 6 months before results can be fully assessed.

  • If a 25% improvement in the skin score is attained after 4 consecutive weeks on an accelerated treatment schedule, the standard treatment schedule may resume1

  • Patients who are maintained in the accelerated treatment schedule may receive a maximum of 20 cycles1

  • Treatment frequency exceeding labeling recommendations may result in anemia

  • There is no clinical evidence of additional benefit from treatment with UVADEX (methoxsalen) Sterile Solution beyond 6 months or on a different schedule1

Prepare Your Patients by Setting Expectations

Help them know before they go

Patient adherence to medical recommendations may be impacted through the use of a patient-centered communication style to help build rapport and establish goals. Presenting patients with factual and clear recommendations can increase a patient’s affinity for adherence.10 Here are some potential points that may help your patients receiving THERAKOS Photopheresis.

Photopheresis is not an immediate-response treatment

Clinical responses to immunotherapy may take longer to assess than with conventional agents because immunotherapy works by triggering an immune response.11*

An assessment is appropriate after the fourth treatment cycle, which is approximately 3 months after initiation. The approved course of treatment is a minimum of 7 cycles.1

*The exact mechanism of UVADEX is not known.

Set expectations that results may come, but it could take at least 3 to 6 months12

These minor lifestyle adjustments may help patients get ready

  • Hydrating prior to the procedure in anticipation of fluid shifts.13 Drinking enough water and juice while reducing alcohol and caffeine intake starting 2 days prior to a procedure is preferred

  • Avoiding high-fat foods the night before and on the day of the procedure.13 Low-fat, healthy meals are preferred

Set expectations that small changes may help prepare the patient for the procedure

UVADEX® (methoxsalen) Sterile Solution is indicated for extracorporeal administration with the THERAKOS® CELLEX® Photopheresis System in the palliative treatment of the skin manifestations of Cutaneous T-Cell Lymphoma (CTCL) that is unresponsive to other forms of treatment.


UVADEX (methoxsalen) Sterile Solution should be used only by physicians who have special competence in the diagnosis and treatment of cutaneous T-cell lymphoma and who have special training and experience in the THERAKOS CELLEX Photopheresis System. Please consult the CELLEX Operator's Manual before using this product.


UVADEX is contraindicated in

  • Patients exhibiting idiosyncratic or hypersensitivity reactions to methoxsalen, other psoralen compounds, or any of the excipients

  • Patients possessing a specific history of a light-sensitive disease state, including lupus erythematosus, porphyria cutanea tarda, erythropoietic protoporphyria, variegate porphyria, xeroderma pigmentosum, and albinism

  • Patients with aphakia because of significantly increased risk of retinal damage

  • Patients that have contraindications to the photopheresis procedure


  • Patients who are receiving concomitant therapy (either topically or systemically) with known photosensitizing agents such as anthralin, coal tar or coal tar derivatives, griseofulvin, phenothiazines, nalidixic acid, halogenated salicylanilides (bacteriostatic soaps), sulfonamides, tetracyclines, thiazides, and certain organic staining dyes such as methylene blue, toluidine blue, rose bengal, and methyl orange may be at greater risk for photosensitivity reactions with UVADEX

  • Oral administration of methoxsalen followed by cutaneous UVA exposure (PUVA therapy) is carcinogenic. Methoxsalen also causes DNA damage, interstrand cross-links and errors in DNA repair

  • Methoxsalen may cause fetal harm when given to a pregnant woman. Women of childbearing potential should be advised to avoid becoming pregnant.  If UVADEX is used during pregnancy, or if the patient becomes pregnant while receiving UVADEX, the patient should be apprised of the potential hazard to the fetus. 

  • Severe photosensitivity can occur in patients treated with UVADEX. Advise patients to wear UVA absorbing, wrap-around sunglasses and cover exposed skin or use a sunblock (SPF 15 or higher), and avoid all exposure to sunlight for twenty-four (24) hours following photopheresis treatment

  • After methoxsalen administration, exposure to sunlight and/or ultraviolet radiation may result in "premature aging" of the skin

  • Since oral psoralens may increase the risk of skin cancers, monitor closely those patients who exhibit multiple basal cell carcinomas or who have a history of basal cell carcinomas

  • Serious burns from either UVA or sunlight (even through window glass) can result if the recommended dosage of methoxsalen is exceeded or precautions are not followed

  • Exposure to large doses of UVA light causes cataracts in animals. Oral methoxsalen exacerbates this toxicity

  • Safety in children has not been established

  • Thromboembolic events, such as pulmonary embolism and deep vein thrombosis, have been reported with UVADEX administration through photopheresis systems for treatment of patients with graft-versus-host disease, a disease for which UVADEX is not approved


Side effects of photopheresis (UVADEX used with the THERAKOS Photopheresis Systems) were primarily related to hypotension secondary to changes in extracorporeal volume (>1%)
For the THERAKOS® CELLEX® Photopheresis Procedure:


The THERAKOS CELLEX Photopheresis System is indicated for use in the ultraviolet-A (UVA) irradiation, in the presence of the photoactive drug 8-methoxypsoralen (8-MOP®), of extracorporeally circulating leukocyte-enriched blood, in the palliative treatment of the skin manifestations of cutaneous T-cell lymphoma (CTCL), in persons who have not been responsive to other forms of treatment.



The THERAKOS CELLEX Photopheresis System is not designated, sold, or intended for use except as indicated.

Certain underlying medical conditions contraindicate THERAKOS Photopheresis, including patients:

  • who cannot tolerate extracorporeal volume loss during the leukocyte-enrichment phase

  • exhibiting idiosyncratic or hypersensitivity reactions to 8-methoxypsoralen/psoralen compounds

  • with coagulation disorders

  • who have had previous splenectomy


  • THERAKOS Photopheresis treatments should always be performed in locations where standard medical emergency equipment is available. Volume replacement fluids and/or volume expanders should be readily available throughout the procedure

  • Patients who may not be able to tolerate the fluid changes associated with extracorporeal photopheresis should be monitored carefully

  • Procedures, such as renal dialysis, which might cause significant fluid changes (and expose the patient to additional anticoagulation) should not be performed on the same day as extracorporeal photopheresis

  • Individual patients may require a heparin dosage that varies from the recommended dose to prevent post-treatment bleeding or clotting during a treatment


  • Hypotension may occur during any treatment involving extracorporeal circulation. Closely monitor the patient during the entire treatment for hypotension

  • Transient pyretic reactions, 37.7-38.9°C (100-102°F), have been observed in some patients within six to eight hours of reinfusion of the photoactivated leukocyte-enriched blood. A temporary increase in erythroderma may accompany the pyretic reaction

  • Treatment frequency exceeding labeling recommendations may result in anemia

  • Venous access carries a small risk of infection and pain
