Disclosed is a method for accelerating wound healing in a mammal. The method includes identifying an unhealed wound site or partially-healed wound site in a mammal; administering a photosensitizer to the mammal; waiting for a time period wherein the photosensitizer reaches an effective tissue concentration at the wound site; and photoactivating the photosensitizer at the wound site. The dose of photodynamic therapy is selected to stimulate the production of one or more growth factor by cells at the wound site, without causing tissue destruction.

Acceleration of wound healing by photodynamic therapy

A method of treating a patient who has osteoarthritic disease by administering a therapeutic composition containing a photoactivatable compound, or a precursor thereof, and administering light of a photoactivating wavelength that activates the compound.

Photodynamic therapy for the treatment of osteoarthritis

Disclosed is a method for modulating wound healing in a mammal. The method includes the steps of: (a) administering a photosensitizer to a mammal that has an unhealed or partially-healed wound; (b) waiting for the photosensitizer to reach an effective tissue concentration at the wound site; (c) photoactivating the photosensitizer by delivering specifically to the wound site light of a effective wavelength and intensity, for an effective length of time. The modulation of wound healing can include hastening healing by administering a low dose of photodynamic therapy. Alternatively, the modulation can include inhibiting fibrosis by administering a high dose of photodynamic therapy. The photosensitizer can be targeted, for example, to macrophages or myofibroblasts. Targeting can be by conjugation to a targeting moiety such as a protein, peptide or microparticle.

Inhibition of fibrosis by photodynamic therapy

A method of treating proliferative diseases of the synovial joint using photodynamic therapy. In particular the method of the invention may be used to destroy synovial tissue in inflammatory joint conditions associated with diseases such as rheumatoid arthritis, lupus erythematosus and other rheumatoid variants. A number of methods of delivery are provided, some of which are non invasive.
