OXSORALEN-ULTRA, a potent photosensitizing agent containing methoxsalen, has been a cornerstone in the treatment of severe, recalcitrant psoriasis for decades. This article delves into the latest clinical trials, market trends, and future projections for this unique pharmaceutical product.
Understanding OXSORALEN-ULTRA
OXSORALEN-ULTRA is a specialized formulation of methoxsalen, a psoralen compound used in conjunction with ultraviolet A (UVA) light therapy for the treatment of severe psoriasis. This combination therapy, known as PUVA (Psoralen + UVA), has been a mainstay in dermatological treatments for patients who haven't responded adequately to other therapies[4].
Mechanism of Action
Methoxsalen works by increasing the skin's sensitivity to UVA light. When combined with controlled UVA exposure, it effectively treats psoriatic lesions by slowing down the rapid cell division characteristic of the condition[6].
Unique Formulation
OXSORALEN-ULTRA is distinct from regular Oxsoralen or 8-MOP capsules. Its soft gelatin capsule formulation provides:
- Greater bioavailability
- Earlier photosensitization onset
- Peak drug levels reached between 0.5 and 4 hours (mean 1.8 hours)[4]
In a well-controlled bioavailability study, Oxsoralen-Ultra Capsules reached peak drug levels in the blood of test subjects between 0.5 and 4 hours (Mean = 1.8 hours) as compared to between 1.5 and 6 hours (Mean = 3.0 hours) for regular Oxsoralen when administered with 8 ounces of milk[4].
Recent Clinical Trials and Research
While OXSORALEN-ULTRA has been in use for many years, ongoing research continues to refine its application and explore potential new indications.
Psoriasis Treatment Efficacy
Recent studies have reaffirmed the efficacy of PUVA therapy using OXSORALEN-ULTRA for severe psoriasis. A retrospective analysis of 200 patients treated with PUVA over five years showed that 84% of patients achieved significant clearance or improvement of their psoriasis[1].
Cutaneous T-cell Lymphoma
Emerging research has explored the use of OXSORALEN-ULTRA in combination with photopheresis for treating cutaneous T-cell lymphoma. A Phase II trial involving 50 patients with advanced-stage mycosis fungoides or Sézary syndrome reported a 70% overall response rate[6].
Vitiligo Treatment
OXSORALEN-ULTRA has shown promise in treating vitiligo when used with controlled UVA exposure. A randomized controlled trial of 100 patients with generalized vitiligo reported repigmentation in 60% of treated areas after 6 months of twice-weekly therapy[6].
Market Analysis
The global psoriasis treatment market, in which OXSORALEN-ULTRA plays a significant role, is experiencing steady growth.
Current Market Size
As of 2024, the global psoriasis treatment market is valued at approximately $21 billion, with phototherapy treatments like PUVA accounting for about 15% of this market[2].

Challenges and Opportunities
While the outlook for OXSORALEN-ULTRA is generally positive, there are both challenges and opportunities on the horizon.
Challenges
-
Safety Concerns: The potential for increased skin cancer risk with long-term use requires careful patient monitoring and may limit extended treatment courses[4].
-
Competition from Biologics: The rise of biological therapies for psoriasis presents a significant competitive challenge.
-
Generic Competition: As patents expire, generic versions of methoxsalen may enter the market, potentially impacting pricing and market share.
Opportunities
-
Combination Therapies: Research into combining OXSORALEN-ULTRA with other treatments could lead to enhanced efficacy and expanded use.
-
Personalized Medicine: Advances in genetic testing may allow for more targeted use of PUVA therapy, optimizing outcomes for suitable patients.
-
Telemedicine Integration: The development of at-home UVA devices could make PUVA therapy more accessible, expanding the potential patient base.
Regulatory Landscape
OXSORALEN-ULTRA's regulatory status remains stable in most markets, but ongoing vigilance is required.
FDA Status
The FDA maintains its approval for OXSORALEN-ULTRA in the treatment of severe, recalcitrant psoriasis. However, the agency continues to monitor long-term safety data[4].
European Regulatory Environment
The European Medicines Agency (EMA) has similar approval status for methoxsalen-based PUVA therapy, with ongoing post-marketing surveillance.
Patient Perspectives
