Provided are methods and uses for treating a cancer or a tumor. In some aspects, the provided methods and uses involve contacting a sample, e.g., containing tumor cells, with a phthalocyanine dye conjugated to a targeting molecule that binds a protein on tumor cell, and illuminating the sample with a wavelength of light suitable for the activation of the phthalocyanine dye. In some aspects, the methods and uses also involve administering the illuminated sample to a subject, such as a subject having a cancer or a tumor. The methods and uses described herein provide for stimulation of the anti-cancer immune response in the subject and the reduction of growth and/or elimination of cancers, tumors and tumor cells in the subject. Also provided are compositions and combinations for use in the provided methods.

A photodynamic therapy (PDT) apparatus and method are disclosed. The PDT apparatus can include a flexible optical applicator that includes a plurality of light emitting devices for producing an irradiance pattern of therapy light to a target area of a patient. The PDT system includes an optical light controller that includes a computer processor. The method disclosed includes determining a treatment plan based on a plurality of therapy light parameters, photosensitizing drug selection, patient specific parameters, optimized light interval and other relevant parameters. The method further includes monitoring the application of the therapy light against the treatment plan and determining an updated treat plan in the event of a deviation from an initial treatment plan.

A fatty acid-biocompatible polymer-photosensitizer conjugate is provided. The conjugate can kill GIP-secreting cells by generating active oxygen upon irradiation with light, and has the effect of increasing insulin, and thus can be effectively used for ameliorating and treating metabolic diseases such as obesity and diabetes.

The present invention relates to a nanoformulated self-assembled pharmaceutical composition for photodynamic therapy. More particularly, the present invention is directed to a self-assembled pharmaceutical composition for photodynamic therapy comprising a photosensitizer, a ligand A which is separated at a specific pH range, and a ligand B of which surface charge changes at a specific pH range and a method for manufacturing the same.

A photodynamic therapy technique for preventing damage to the fovea of the eye or another body portion of a patient is disclosed herein. In one embodiment, a treatment laser is applied to a body portion of a patient using a painting technique, the treatment laser being configured to provide paint brush-type photodynamic therapy (PPDT) using the painting technique to the body portion of the patient by emitting light of a predetermined wavelength that is absorbed by tissue of the body portion of the patient to which a photosensitizer has been applied, the body portion of the patient being afflicted by a medical condition. The application of the treatment laser to the body portion of a patient using the painting technique treats the medical condition, reduces the symptoms associated with the medical condition, and/or alleviates the medical condition.

Methods for treatment of wAMD with an active CNV lesion of less than 50% of the total lesion size and pharmaceutical compositions for the use therein are disclosed.

The present disclosure relates to a chlorin derivative or a pharmaceutically acceptable salt thereof, a preparation method thereof, an anti-tumor composition including the chlorin derivative or the pharmaceutically acceptable salt thereof, use of the chlorin derivative or the pharmaceutically acceptable salt thereof in the treatment of a tumor, and a combination of the chlorin derivative or the pharmaceutically acceptable salt thereof and an ultrasound medical system. The chlorin derivative or the pharmaceutically acceptable salt thereof has a structure represented by formula (I), and the ultrasonic medical system comprises a transducer ultrasonic bed and a contact agent. The chlorin derivative of the present disclosure can be used in photodynamic therapy and sonodynamic therapy, thereby effectively inhibiting and treating cancer.

Provided are a nanoparticle complex for oral administration, a pharmaceutical composition for oral administration for treating brain tumors, including the same, a pharmaceutical composition for oral administration for photothermal therapy (PTT) or photodynamic therapy (PDT), and a method of treating brain tumors using the pharmaceutical composition, and the nanoparticle complex for oral administration has not only excellent metal-enhanced fluorescence (MEF) but also excellent metal-enhanced reactive oxygen generation (MERos) due to a surface plasma resonance effect through a bond with the photosensitizer while having excellent oral absorption rate through a bond with lactoferrin, and when a pharmaceutical composition including the nanoparticle complex is administered, the pharmaceutical composition can effectively permeate the small intestinal epithelium and the blood-brain barrier without toxicity and can be effectively accumulated in brain tumor tissue to have an excellent photothermal therapy (PTT) or photodynamic therapy (PDT) effect in brain tumor tissue. In addition, there is an advantage in that brain tumors can be effectively treated by adjusting the order of photothermal therapy (PTT) and photodynamic therapy (PDT), and the like after administering a pharmaceutical composition including a nanoparticle complex for oral administration.

Plasmonics-active metal nanostars are provided that can be used for treating and detecting cells in a subject. The modes of treatment include a photo-activated drug, which is activated by the photo-response of the nanostar to electromagnetic stimulation; a thermally-activated drug, which is activated by a thermal response of the nanostar to electromagnetic stimulation; and the thermal response of the nanostar itself to electromagnetic stimulation, which may directly or indirectly cause the death of an undesirable cell. Uptake of nanostars by undesirable cells may also aid in detection, by enhancing contrast or otherwise transforming electromagnetic stimulation during imaging.

Disclosed are a cyanine dye compound and a preparation method therefor, and a dual-function agent for photodynamic therapy and a preparation method therefor. The provided cyanine dye compound is connected to multiple markers, which improves the accuracy of combination of dye and tumor cells, effectively reduces the background value, and avoids excessive residues in the liver. The provided cyanine dye compound is conjugated with the photosensitizer at 2′″ position, so that tumor highly absorbs the conjugates.
