The study demonstrates the potential of combined Hsp90-targeted PDT and PD-1/PD-L1 blockade in breast cancer immunotherapy and abscopal effect i.e. efficacy on distal tumors.   Continue reading →

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for the treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple photosensitizer to a tumor-targeting agent that binds to a specific antigen expressed on the Continue reading →Customer case Research by: Duke University, founded in 1924, is one of the leading and wealthiest private research universities in the USA.

Kim Lyerly   ML7710 was used for in vivo and ML8500 coupled to ML7710 for in vitro studies of HSP90-targeted verteporfin PDT for breast cancer. This strategy has both diagnostic and therapeutic potential across all breast cancer subtypes found up to few cm in depth, and may provide Continue reading →
