Imaging & Therapy
Photodynamic Therapy (PDT)
Photodynamic therapy (PDT) is an innovative cancer treatment currently used for skin, lung, head-and-neck and esophageal cancers, as well as other non-oncological medical conditions.
In PDT therapy, a photosensitive compound is applied directly to the skin or injected intravenously. While healthy cells shed the drugs, the agents remain heavily concentrated in cancer cells. The tumor is then exposed to an appropriate wavelength of a laser light, which produces a cytotoxic agent within the tumor, causing selective destruction of the cancer cells.
The compounds being developed by Photolitec are considered the next generation of PDT agents with imaging capability. They are associated with only limited skin phototoxicity, a major limitation of most PDT compounds. PDT is not currently used for treating large or deep-seated tumors of the body; however, Photolitec’s new long-wavelength-absorbing compounds will help to image and treat deeply-seated tumors.
