Filter by:As many as 85 % of renal transplant patients may suffer from viral warts with a high degree of treatment resistance. Promising results of hLAC (human lactalbumin complex with lipid) point to a beneficial effect without noticeable side effects of bLAC (bovine lactalbumin complex with lipid). The aim of first clinical trial with bLAC is to show proof of concept in treatment of cutaneous wart lesions on hands and/or feet after local administration of bLAC in two dose groups to immune suppressed, kidney transplanted patients.
Photodynamic therapy (PDT) has been developed as a promising new cancer treatment modality, which involves the uptakes of a photosensitizer by tumor cells, followed by the activation of photosensitizer with approximate wavelength of light. The mechanisms of the PDT-induced cytotoxic effect relate to singlet oxygen and other reactive oxygen intermediates generated by PDT, which give rise to cellular stress and cause cell death. Previously, using the homemade LED light source, we have shown that ALA-PDT is effective for the treatment of premalignant lesions such as mucosal dysplasia and carcinoma in situ of oral cavity. Due to the advantages of low cost, high reliability, and portability, LED light source provides an alternative approach for the light irradiation of PDT. Verruca vulgaris are benign skin papillomas caused by the human papilloma virus (HPV). They are very common and can affect many different sites including the face, hands, feet and genitalia. Although the present therapeutic approaches are more or less effective in eradicating the lesions, relapses are very common. Furthermore, at times the anatomical location and depth of lesions often make the treatment difficult, time-consuming and painful. Therefore, it is necessary to develop new modalities for wart treatment. The purpose of this clinical trial is to develop topical ALA-PDT as an alternative treatment of wart but without the unwanted side effects of pain and burning. To fulfill this goal, the following works will be performed. First, topical ALA formulation and LED array will be specifically designed and developed for the skin lesions. Second, the efficacy of the ALA formulation designed for wart treatment will be evaluated with in vivo fluorescence imaging system. Third, the therapeutic efficacy of ALA-PDT will be evaluated by using a LED array designed for skin irradiation. Forth, the unwanted side effects of pain and burning will be further compared between red and green LED array.
