Prostate-specific Membrane Antigen-targeted Photosensitizers for Photodynamic Therapy

Case ID:
C12525

Invention novelty: This invention is a novel drug composition that can target prostate tumors in vivo for use in photodynamic therapy (PDT).




Value Proposition:


Currently, prostate cancer treatment often requires invasive surgery or treatment with drugs that may cause adverse side-effects. This current technology is advantageous as it is;


•   Minimally invasive


•   Unlike other PDT cancer therapeutic drugs it targets the tumor, resulting in fewer side-effects.


•   Can compete with immune-based drug treatments as a targeted treatment, with potentially fewer side-effects.




Technical Details:


Johns Hopkins researchers have developed a pharmacological agent for use in prostate cancer and solid-tumor


photodynamic therapy). To increase PDT efficiency, tissue-specific or tumor-specific targeting molecules are used. This technology is a molecule that specifically targets prostate cancer and potentially many-solid tumor cancer types. The synthesized molecular compound utilizes a photosensitize and a prostate targeting molecule. To date, the inventors have made and tested 2 separate molecules, which effectively and specifically target prostate tumors.




Looking for Partners: To develop and commercialize the technology as a therapeutic for prostate cancer and potentially some solid-tumor cancers.




Stage of Development: Pre-Clinical




Data Availability: Animal data available.
