Sun Pharmaceutical Industries Limited announced today that the U.S. Food and Drug Administration (FDA) has granted premarket approval for its next-generation BLU-U® Blue Light Photodynamic Therapy (PDT) Illuminator. The new device features light-emitting diode (LED) panels, replacing the fluorescent tubes used in previous models, while maintaining the same therapeutic indications.
The LED BLU-U, used in combination with LEVULAN® KERASTICK® (aminolevulinic acid HCl) Topical Solution, 20%, is indicated for treating minimally to moderately thick actinic keratoses (AK) on the face, scalp, or upper extremities. The approval was granted under the FDA's Real-Time Review Program, reflecting the robustness of Sun Pharma's submission.
Enhanced Design and Functionality
The next-generation device maintains the proven efficacy and safety profile of the original BLU-U system while introducing several significant improvements. The new model features:
- A more flexible five-panel configuration
- Reduced footprint in dermatology offices
- Optimized LED arrangement for consistent light distribution
- Lighter weight for improved mobility
- Updated functions designed to enhance patient comfort
"We are pleased to receive the FDA's approval of LED BLU-U and look forward to seeing the positive impact this next generation device will have for those living with actinic keratosis," said Abhay Gandhi, Sun Pharma North America CEO. "As a company committed to innovation, we are confident that this new LED BLU-U model will provide improved efficiency and reliability while maintaining the safety and efficacy that healthcare professionals and people with AKs have come to trust from Sun Pharma."
Clinical Significance of Photodynamic Therapy for AK
Actinic keratosis is a chronic condition characterized by rough, dry, and scaly patches on the skin resulting from extended sun exposure. These lesions, which can vary in size from tiny pinheads to quarters, are commonly found on sun-exposed areas such as the face, scalp, arms, and hands. While initially benign, AK lesions have the potential to progress to squamous cell carcinoma if left untreated.
The LEVULAN KERASTICK + BLU-U system works through a selective photodynamic mechanism. The topical solution is preferentially absorbed by AK lesions, and when activated by the blue light, generates reactive oxygen species that produce localized cytotoxic effects, resulting in lesion clearance. This targeted approach minimizes damage to surrounding healthy tissue.
The LED technology in the new device is expected to provide more consistent light distribution, potentially enhancing treatment precision and overall outcomes compared to the previous fluorescent tube model.
Treatment Advantages and Market Position
LEVULAN KERASTICK + BLU-U blue light therapy has been a trusted treatment option for dermatologists for over 20 years. The system offers several advantages:
- Effective clearance of AK lesions in one or two in-office visits
- Non-invasive treatment modality
- Selective targeting of abnormal keratinocytes
- Established safety profile
The photodynamic therapy approach represents an important alternative to other AK management strategies such as cryotherapy and topical chemotherapeutics. The reduced size and weight of the new LED BLU-U device make it more feasible for integration into a wider range of dermatology practice settings.
Availability and Implementation
Sun Pharma has indicated that the LED BLU-U will be available for delivery in the near future. Healthcare professionals interested in details regarding availability, ordering, or implementation are encouraged to contact their Sun Pharma Specialty Dermatology representative or visit www.levulanhcp.com for more information.
The approval of this next-generation device reinforces Sun Pharma's position in the dermatology space and highlights the company's commitment to advancing treatment options for patients with actinic keratosis. As the world's leading specialty generics company with a significant presence in dermatology, Sun Pharma continues to focus on delivering high-quality medicines trusted by physicians and consumers in over 100 countries.
