摘要:
This invention relates to a novel crystalline polymorph of hexyl-5-aminolevulinate hydrochloride, referred to hereinafter as Form C, which is useful as precursor of a photo sensitizer in the photodynamic diagnosis and treatment of metabolically active cells related to diseases such as cancer of the uterus, cervix, vagina, rectum, colon, lower gastrointestinal tract; infection associated with cancer caused by human papilloma virus; non-cancerous lower gastrointestinal tract a human; inflammatory bowel disease; ulcerative colitis; Crohn's disease; inflammatory bowel syndrome; dysplasia of the female reproductive system; anus; penis; rosacea; and acne and which is suitable for use as the active ingredient of a commercial pharmaceutical product. The invention relates further to methods of preparing Form C and using it in the described pharmaceutical compositions.
摘要:
This invention relates to the treatment and diagnosis of abnormalities of the epithelial-lined surface of the esophagus and, in particular, to esophageal stents having a surface coating comprising a photosensitizing agent or a precursor thereof for use in methods of photodynamic treatment (PDT) or photodynamic diagnosis (PDD) of the esophagus. The stents find particular use in methods of diagnosing and/or treating Barrett's esophagus and in diagnostic methods for monitoring the progression of the disease.
摘要:
Provided is a therapeutic agent capable of treating allergic rhinitis in a safe, simple, and noninvasive manner substantially without side effects and physical distress to patients. Provided is a therapeutic agent for allergic rhinitis for 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) comprising 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt of the 5-aminolevulinic acid or the derivative as an active ingredient, and used in ALA-PDT in which light having a wavelength of 400 nm to 700 nm is irradiated; and particularly provided is a therapeutic agent for allergic rhinitis in a locally applied solution form, a water-soluble ointment-dissolved form, a jelly-dissolved form, or the like. The therapeutic agent does not require the conduct of 5-aminolevulinic acid-based photodynamic diagnosis (ALA-PDD) for detecting a site of protoporphyrin IX (PpIX) accumulation radiating light having a wavelength of 610 nm to 650 nm under irradiation of excitation light having a wavelength of 380 nm to 420 nm before ALA-PDT.
摘要:
It is intended to provide a therapeutic and/or diagnostic agent that can be used in photodynamic therapy (PDT) or photodynamic diagnosis (PDD) capable of utilizing infrared-spectrum light such as near-infrared light (NIR), infrared light, or far-infrared light, which attains a deep body penetration. The present invention provides a photodynamic therapeutic or diagnostic agent or a photodynamic therapeutic or diagnostic kit for cancer or infectious disease, comprising: a particle (e.g., a lanthanide particle) that emits upconversion luminescence by infrared-spectrum light such as near-infrared light having a wavelength of 0.7 μm to 2.5 μm; and a photosensitizer (e.g., porphyrin) or a 5-aminolevulinic acid group.
摘要:
The invention provides use of a photosensitiser, which is a derivative (e.g., an ester) of 5-aminolevulinic acid (5-ALA) or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for use in the prevention or treatment of acne.
摘要:
The invention relates to a dermal application system for aminolevulinic acid-derivatives, i.e. a pressure-sensitive matrix system containing a crystalline aminolevulinic acid derivative.
摘要:
The invention provides use of a photosensitiser, which is a derivative (e.g., an ester) of 5-aminolevulinic acid (5-ALA) or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for use in the prevention or treatment of acne.
摘要:
This invention relates to solid compositions and solid pharmaceutical products for use in methods of photodynamic diagnosis of cancer, pre-cancerous and non-cancerous conditions in the lower part of the gastrointestinal system. The solid pharmaceutical compositions and pharmaceutical products comprise an active ingredient which is 5-aminolevulinic acid (5-ALA) or a precursor or derivative of 5-ALA or pharmaceutically acceptable salts thereof. The invention relates further to methods of photodynamic diagnosis of cancer, pre-cancerous and non-cancerous conditions of the lower gastrointestinal tract, wherein the solid pharmaceutical compositions and pharmaceutical products are used.
摘要:
A low concentration formulation for hydrophobic photosensitizers (PS) and method for photodynamic therapy (“PDT”) using the disclosed low concentration formulations provide for more accurate, more efficient and more convenient dosing. The inventive formulation (1) reduces the time for a therapeutically effective level of photosensitizer to accumulate in diseased tissue and (2) reduces the time for achieving a sufficient ratio of photosensitizer in diseased tissue vs. healthy tissue. The inventive formulation reduces the time interval between PS application/administration and irradiation (the drug-light interval or “DLI”) and can provide for a “same day” PDT treatment option. 0.08 mg/ml to 1.3 mg/ml meta Tetra-Hydroxy-Phenyl Chlorin (m-THPC) as the photosensitizer in a mixture of pure propylene glycol and ethanol (3:2 volume ratio) accumulates in diseased tissue and differentiates between diseased tissue and normal tissue sufficiently quickly for ‘one day’ or overnight administration and activation treatment procedures to be possible.
