Provided are conjugates, e.g., dual conjugates, compositions and methods for use in photoimmunotherapy, such as photoimmunotherapy induced by activation of a phthalocyanine dye in the dual conjugate. In some embodiments, the dual conjugate contains a targeting molecule and a therapeutic agent. In some embodiments, the phthalocyanine-dye in the conjugate, e.g., dual conjugate, can be activated by irradiation with near-infrared light. Also provided are therapeutic methods using the conjugates, e.g., dual conjugates, and compositions for treatment of a lesion associated with diseases and conditions, including tumors or cancers. Features of the conjugates, e.g., dual conjugates, compositions, combinations and methods, including the dose of the conjugate, provide various advantages, such as efficient delivery and targeting of the therapeutic agent to the site of the lesion. |
