What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Description

Uvadex (methoxsalen) is a photoactive psoralen derivative used in conjunction with extracorporeal photopheresis (ECP) for the palliative treatment of the skin manifestations of cutaneous T-cell lymphoma (CTCL) in patients who are unresponsive to other forms of treatment. Methoxsalen intercalates into DNA and, upon activation with ultraviolet A (UVA) light, forms covalent cross-links that inhibit DNA synthesis and cell division, inducing apoptosis in pathogenic T lymphocytes. Uvadex is administered ex vivo as part of a leukapheresis and UVA irradiation procedure, not as a systemic or topical agent.

Routes of administration

Extracorporeal (via photopheresis), oral (other formulations)

Directions

Uvadex is used only in specialized ECP systems (e.g., Therakos CELLEX):

  • Each treatment involves extracorporeal exposure of leukocytes to UVA light in the presence of methoxsalen.
  • Recommended dose: 0.017 mg of methoxsalen per mL of collected buffy coat cells, typically up to a maximum of 200 mcg per treatment.
  • Treatments are often administered on 2 consecutive days every 4 weeks, with frequency adjusted based on clinical response.

Do not inject Uvadex directly into the patient. It is for ex vivo use only under direct supervision by trained clinicians in photopheresis units.

Ingredients

Each 10 mL vial of Uvadex contains:

  • Methoxsalen 10 mcg/mL (total 100 mcg per vial)

Inactive ingredients:

  • Sodium chloride, polysorbate 80, hydrochloric acid or sodium hydroxide (pH adjustment), and water for injection

Contraindications

Uvadex is contraindicated in patients with:

  • Photosensitivity disorders (e.g., lupus erythematosus, porphyria)
  • Aphakia (due to high risk of retinal damage)
  • Known hypersensitivity to methoxsalen
  • Active skin cancers or invasive squamous cell carcinoma
  • Severe hepatic impairment

Cautions

Uvadex is not for oral or direct IV administration. Patients undergoing treatment must wear UVA-blocking eye protection during daylight hours for 24 hours post-treatment to prevent ocular damage. Long-term use is associated with increased risk of skin aging and skin cancers, particularly squamous cell carcinoma. Monitor for photosensitivity reactions, skin changes, and cataract formation. Use with caution in patients with cardiovascular disease or those who have had prior extensive PUVA exposure. Avoid use during pregnancy unless clearly indicated.

Side Effects

Potential side effects may include:

  • Erythema or mild skin redness
  • Nausea or headache
  • Hypotension during ECP
  • Photosensitivity reactions
  • Long-term: skin aging, increased risk of skin cancers, cataracts (if protective eyewear is not used)
  • Rare: allergic reactions or severe burns with inappropriate UVA exposure
