Abstract:
This invention relates to semi-solid compositions and semi-solid pharmaceutical products for use in the photodynamic treatment (PDT) of cancer, pre-cancerous conditions and non-cancerous conditions in the female reproductive system, the anus and the penis, preferably for use in PDT of endometrial, cervical, vulvar, vaginal, anal and penile dysplasia and HPV infections of the uterus, cervix, the vulva, the vagina, the anus and the penis. The semi-solid compositions and pharmaceutical products comprise an active ingredient which is 5-aminolevulinic acid (5-ALA) or a precursor or derivative of 5-ALA or pharmaceutically acceptable salts thereof. The invention relates further to methods of PDT of cancer, pre-cancerous conditions and non-cancerous conditions in the female reproductive system, the anus and the penis, wherein said semi-solid compositions and pharmaceutical products are used.

Abstract:
The present invention relates to the use of a photosensitiser which is 5-ALA or a precursor or derivative thereof (e.g. an ALA ester), in the manufacture of a pharmaceutical product for use in the photodynamic treatment or diagnosis of cancer, an infection associated with cancer, or in the treatment or diagnosis of a non-cancerous condition, wherein said pharmaceutical product is in the form of a solid. The invention also relates to solid pharmaceutical products for use in such methods, e.g. suppositories, pessaries, tablets, pellets and capsules which comprise 5-ALA or a precursor or derivative thereof (e.g. an ALA ester) and at least one pharmaceutically acceptable carrier or excipient. Such products are particularly suitable for use in the photodynamic treatment or diagnosis of cancerous or non-cancerous conditions in the lower part of the gastrointestinal system or in the female reproductive system, e.g. in the treatment or diagnosis of colorectal cancer or cervical cancer.
