Definitions

  • the present invention relates inter alia to compositions comprising at least . one electroluminescent compound which can be used for the treatment and/or prophylaxis of therapeutic diseases and/or cosmetic conditions.
  • the present invention also relates to devices comprising said compositions and their applications in therapeutic and cosmetic applications.
  • Phototherapy also called light therapy
  • the therapy using light is already being used to treat wounds, injuries, neck pain, osteoarthritis, the side effects of chemotherapy and radiotherapy, for instance.
  • the borders between therapeutic and cosmetic applications are vague and depend on individual circumstances and the assessment of a physician.
  • therapeutic conditions are associated with cosmetic consideration.
  • the treatment or prophylaxis of acne may have both therapeutic and cosmetic components, depending on the degree of the condition.
  • the same accounts for psoriasis, atopic dermatitis and other diseases and/or conditions.
  • Many diseases and conditions are associated with apparent implications which are often represented by a change in the visibility of a subject's skin, for instance. These cosmetic or aesthetic changes can lead to psychological modifications resulting, at least in part, in serious diseases.
  • Some conditions or diseases may have an emphasis on cosmetic components, even if therapeutic elements may also play a role. Some of these are selected from anti-ageing, anti-wrinkle, the prevention and/or therapy of acne and vitiligo.
  • Many diagnostic tools or devices may also require light sources, e.g., in order to determine blood characteristics such as bilirubin, oxygen, or CO.
  • the skin is the main target to be radiated, but other targets of the human or animal body can also be accessed by phototherapy. These targets include, but are not limited to, the eye, wounds, nails, and internal parts of the body.
  • Light can also be used in order to facilitate or support sterilization and/or disinfection of wounds, beverages, nutrition, for example.
  • One of the primary effects of phototherapy is the stimulation of metabolism in the mitochondria. Certain wavelengths of light stimulate cytochrome c oxidase, an enzyme which is responsible for the production of the essential cellular energy in the form of adenosine triphosphate (ATP).
  • cytochrome c oxidase an enzyme which is responsible for the production of the essential cellular energy in the form of adenosine triphosphate (ATP).
  • ATP is required for cellular energy transfer in order to drive thermo- dynamically unfavoured biochemical reactions and as cellular energy storage. ATP can also act as signal molecule in order to modulate other biochemical molecules (e.g. reactive oxygen species and nitric oxide) that lead to ageing and cell death (oxidative stress). After phototherapy, the cells show an increased metabolism, they communicate better and they survive stressful conditions in a better way.
  • biochemical molecules e.g. reactive oxygen species and nitric oxide
  • Such principle can be applied for medicinal therapeutic and cosmetic applications, such as wound healing, connective tissue repair, tissue repair, prevention of tissue death, relief of inflammation, pain, acute injuries, chronic diseases, metabolic disorders, neurogenic pain and seasonal effect disorders.
  • PDT photodynamic therapy
  • a light-sensitive therapeutic agent known as a photo- pharmaceutical is supplied externally or internally to an area of the body which is to be treated. That area is then exposed to light of a suitable frequency and intensity to activate the photopharmaceutical.
  • photopharmaceutical agents are currently available. For example there are topical agents such as 5-aminolevulinic acid hydrochloride (Crawford Pharmaceuticals), methylaminolevulinic acid (Metfix®, Photocure).
  • injectable drugs used primarily for internal malignancies, including Photofin® (from Axcan) and Foscan® (from Biolitech Ltd). Often, the drug is applied in a non-active form that is metabolised to a light-sensitive photopharmaceutical.
  • the primary technique for supplying light to the photopharmaceutical is to project light of a suitable wavelength from standalone light sources such as lasers or filtered arc lamps. These sources are cumbersome and expensive, and are therefore only suitable for use in hospitals. This leads to inconvenience for the patient, and high cost for the treatment. High light irradiances are needed in order to treat an acceptable number of patients per day (for the treatment to be cost effective) and to avoid unduly inconveniencing the patient.
  • WO 98/46130 and US 6096066 disclose arrays of LEDs for use in photo- dynamic therapy.
  • the small LED sources taught therein result in uneven light incident on the patient. Fabrication of arrays is complicated, because of the large number of connections required.
  • the devices shown therein are designed for hospital treatment.
  • GB 2360461 discloses a flexible garment which uses a conventional photodynamic therapy light source to produce light which is then transmitted through optical fibres. As such light sources are heavy, the device is not ambulatory and is limited to hospital use.
  • US 5698866 discloses a light source using over-driven inorganic LEDs. The resulting light output is not even. A heat-sinking mechanism is required, and the device is suitable only for hospital treatment.
  • WO 93/21842 disclose light sources using inorganic LEDs. Although transportable, the device is not suitable for ambulatory use by a patient at home and clinical treatment is envisaged.
  • a further problem with existing approaches is that it can be difficult to achieve uniform illumination with such sources, especially on curved body parts.
  • An essential prerequisite for the application of light in the fields mentioned above is the device.
  • the commercial available systems nowadays are mostly based on lasers.
  • theses systems are hospital based, i.e. stationary devices.
  • a portable home-use technology is required.
  • some research has been devoted in this direction.

  • EP 1444008 discloses the Devices for the treatment of photodynamic therapy comprising OLEDs.
  • Organic light emitting diodes have many advantages over their inorganic counterpart (light emitting diodes - LEDs) in that they are intrinsically flexible, and can be coated on large area by, for example, printing technologies, such as ink jet printing and screen printing.
  • printing technologies such as ink jet printing and screen printing.
  • active metals such as Ba and Ca
  • cathode active metals, such as Ba and Ca
  • Oxygen and humidity can inhibit or destroy the function of OLEDs. There is, therefore, a need for the development of novel thin light sources without the drawbacks as described above.
  • organic light emitting electrochemical cells can be used as light sources for the treatment and prophylaxis of medical and/or cosmetic diseases and conditions.
  • OLECs are very simple in their structure and therefore easily prepared.
  • the preparation of devices with curved or three dimensional surfaces is in the case of OLECs less complex as compared to the preparation of such surfaces in OLEDs. This is due to the fact that the requirements relating to homogeneity of the layer is less stringent.
  • the production costs in particular for mass production are much lower as compared to the ones of OLEDs.
  • OLECs do not rely on air-sensitive charge-injection layers or metals such as Ba or Cs for electron injection, which further simplifies their preparation and makes them more cost efficient, as compared to
  • OLEDs and LEDs are diodes with forward bias and reverse bias.
  • l-V (current-voltage) curves of both OLEDs and LEDs are asymmetric. They represent semiconductor technologies whereas an OLEC is basically an electrochemical or more precisely an electrolytic cell.
  • Charge transport in OLEDs occurs via the movement of holes and electrons from molecule to molecule until holes and electrons form so called excitons, i.e. electron-hole-pairs. Light is emitted when electrons and holes recombine.
  • the electrolyte upon applying a voltage, the electrolyte is oxidized at the anode and reduced at the cathode.
  • Another possible type of light emitting device comprising ionic materials is a device with an ionic p-n junction as reported by Daniel A. Bernards, et al., Science 2008, 313, 1416, wherein two layers are laminated together. One of the layers has a mobile anion and the other one has a mobile cation; by ion exchange an ionic p-n junction is formed in the interface between two layers. Here the ionic p-n junction is formed before the voltage is applied. The emission of light can then occur in the p-n junction.

  • the combination therapy can have a synergistic effect and can reduce the side effects of traditional treatment strategies (e.g. the side effects of tetracyclines). This is due to the fact, that smaller doses of the drugs may be required when following the combined approach as outlined herein.

  • Acne vulgaris (commonly called acne) is a common skin condition, caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, via androgen stimulation. It is characterized by noninflammatory follicular papules or comedones and by inflammatory papules, pustules, and nodules in its more severe forms.
  • Acne vulgaris affects the areas of skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms. Acne lesions are commonly referred to as pimples, blemishes, spots, zits, or simply acne.
  • acne is usually caused by an increase in male sex hormones, which people of both genders accrue during puberty. For most people, acne diminishes over time and tends to disappear - or at the very least decrease - after one reaches one's early twenties. There is, however, no way to predict how long it will take to disappear entirely, and some individuals will carry this condition well into their thirties, forties and beyond.

  • the upper arms can also have acne, but lesions found there are often keratosis pilaris. Typical acne lesions are comedones, inflammatory papules, pustules and nodules. Some of the large nodules are also called cysts and the term nodulocystic has been used to describe severe cases of inflammatory acne.
  • the treatment apparently works even better if used with a mixture of the violet/blue light and red visible light (e.g. 660 nm) resulting in a 76% reduction of lesions after three months of daily treatment for 80% of the patients; and overall clearance was similar or better than benzoyl peroxide. Unlike most of the other treatments few if any negative side effects are typically experienced, and the development of bacterial resistance to the treatment seems very unlikely. After treatment, clearance can be longer lived than is typical with topical or oral antibiotic treatments; several months is not uncommon. In addition, basic science and clinical work by dermatologists has produced evidence that intense blue/violet light (405 to 425 nm) can decrease the number of inflammatory acne lesion by 60 to 70% in four weeks of therapy, particularly when the P. acnes is pre-treated with delta-aminolevulinic acid (ALA), which increases the production of porphyrins.

  • Jaundice which is also known as icterus, is a yellowish discoloration of the skin, the conjunctival membranes over the sclerae (whites of the eyes), and other mucous membranes. The discoloration is caused by hyperbilirubinemia (increased levels of bilirubin in the blood). This hyperbilirubinemia subsequently causes increased levels of bilirubin in the extracellular fluids. Jaundice is classified in three groups, pre-hepatic (hemolytic) jaundice, hepatic (hepatocellular) jaundice, and post-hepatic (obstructive) jaundice.
  • Pre-hepatic jaundice is caused by anything which causes an increased rate of hemolysis, i.e. breakdown of red blood cells. In tropical countries, malaria can cause jaundice in this manner. Certain genetic diseases, such as sickle cell anemia, spherocytosis and glucose 6-phosphate dehydrogenase deficiency can lead to increased red cell lysis and therefore hemolytic jaundice. Commonly, diseases of the kidney, such as hemolytic uremic syndrome, can also lead to coloration. Defects in bilirubin metabolism also present as jaundice. Jaundice usually comes with high fevers. Rat fever (leptospirosis) can also cause jaundice.
  • Hepatic jaundice causes include acute hepatitis, hepatotoxicity and alcoholic liver disease, whereby cell necrosis reduces the liver's ability to metabolise and excrete bilirubin leading to a buildup in the blood. Less common causes include primary biliary cirrhosis, Gilbert's syndrome (a genetic disorder of bilirubin metabolism which can result in mild jaundice, which is found in about 5% of the population), Crigler-Najjar syndrome, metastatic carcinoma and Niemann-Pick disease, type C. Jaundice seen in the newborn, known as neonatal jaundice, is common, occurring in almost every newborn as hepatic machinery for the conjugation and excretion of bilirubin does not fully mature until approximately two weeks of age.
  • Post-hepatic jaundice also called obstructive jaundice
  • Post-hepatic jaundice is caused by an interruption to the drainage of bile in the biliary system.
  • the most common causes are gallstones in the common bile duct, and pancreatic cancer in the head of the pancreas.
