Definitions

  • NPN NICTOTINAMIDE MONONUCLEOTIDE
  • the present invention relates to the use of nicotinamide mononucleotide (NMN), one of its pharmaceutically acceptable derivatives or one of its pharmaceutically acceptable salts, as well as compositions comprising it, for the treatment and / or prevention of polyarthritis rheumatoid.
  • NNN nicotinamide mononucleotide
  • a joint brings together two bone ends covered with cartilage as well as a synovial membrane enveloping the whole.
  • the role of the synovial membrane is to facilitate joint movements, by secreting a lubricant: the synovial fluid.
  • Inflammatory rheumatism mainly consists of inflammation of the synovial membrane. Too much synovial fluid is then secreted and the synovial membrane thickens abnormally. The soft tissues and bony surfaces of the joint are damaged. The joint becomes abnormally swollen and painful, preventing movement.
  • Rheumatoid arthritis is a chronic inflammatory rheumatism that most commonly affects the hands, wrists and knees but can also spread to other joints. Polyarthritis is sometimes associated with the presence of rheumatoid factor in the patient's blood and can lead to irreversible damage to the joints.
  • the treatments for polyarthritis include, on the one hand, symptomatic treatment to relieve inflammatory flare-ups and on the other hand, maintenance therapy.
  • Symptomatic treatments mainly comprise the administration of analgesics to reduce pain, non-steroidal anti-inflammatory drugs (NSAIDs) as well as cortisone or its derivatives to reduce inflammation.
  • NSAIDs non-steroidal anti-inflammatory drugs
  • cortisone or its derivatives to reduce inflammation.
  • chronic administration of these drugs damages the stomach, liver and kidneys, among other things.
  • their effectiveness decreases over time requiring increased doses or the use of more aggressive drugs and often causing more side effects.
  • cortisone derivatives induces in particular bone fragility, neuropsychiatric effects, muscle wasting and a reduction in immunity, leaving the patient vulnerable to infections.
  • DMARDs most often include the administration of methotrexate, an anticancer drug successfully used to prevent and reduce the number of inflammatory flares.
  • methotrexate an anticancer drug successfully used to prevent and reduce the number of inflammatory flares.
  • this drug includes many side effects such as fever, anemia, respiratory problems, teratogenic risks and bone marrow toxicity among other risks. Therefore, it is not well tolerated by all patients.
  • Other medicines, in place of or in conjunction with methotrexate are used such as certain antimalarials and inhibitors of TNF (for "Tumor Necrosis Factor”), a protein involved in inflammatory processes.
  • TNF for "Tumor Necrosis Factor”
  • none of these drugs are free from side effects. In particular, there is a risk of weakening the immune system, as well as high toxicity on the patient's vital organs such as the liver and kidney.
  • rheumatoid arthritis stiffens and deforms the joints.
  • the gestures of daily life are becoming more and more difficult for patients to perform. Patients therefore end up needing to change their daily lives, quit their work and depend on outside help, which among other things implies a considerable cost for the health systems.

  • mice were divided into four groups each comprising ten mice: (i) a control group in which the mice are treated with the vehicle, that is to say a 0.9% NaCl solution (10 mL / kg) noted " Vehicle ”; (ii) a group of mice treated with K / BxN serum (10 mL / kg) denoted “KBxN”; (iii) a group of mice treated with serum K / BxN + dexamethasone (1 mg / kg) denoted “KBxN + dexamethasone”; and (iv) a group of mice treated with K / BxN + NMN serum (185 mg / kg) denoted “KBxN + NMN”.
  • the K / BxN serum is a serum obtained from genetically modified mice used as a model of rheumatoid arthritis. Administration of this serum induces chronic inflammation of the joints in mice to mimic rheumatoid arthritis.
  • Dexamethasone is a derivative of cortisone, a treatment traditionally used to fight against flare-ups of rheumatoid arthritis.
  • NMN is used here in the form of a zwitterion.
  • KBxN serum and NMN are administered to mice intraperitoneally.
  • Dexamethasone is administered subcutaneously.
  • mice are treated for 9 days according to the conditions mentioned above.
  • Mice paws Photos are taken on the 6th day of treatment.
  • the blood of the mice is taken on the 6 th and 10 th days of treatment.
  • Tissues were collected at I0 th day of treatment for histological analysis, the day after stopping treatment.
  • the clinical score and the weight of the mice are measured daily. The clinical score is established by measuring the thickness of each of the animal's front and hind legs, and by adding the associated score according to Table 1 below:
  • mice in the control group did not lose weight during the duration of the experiment.
  • administration of K / BxN serum induced significant weight loss in the three treated groups, indicating treatment-related distress in the animal.
  • the administration of dexamethasone induces an additional and significant weight loss compared to the group treated with KBxN alone as well as to the "KBxN + NMN" group.
  • NMN did not induce significant weight loss compared to the "KBxN" treated group. Therefore, NMN is well tolerated and more specifically, NMN is better tolerated than dexamethasone.
  • FIG. 2 shows the evolution of the clinical score among the different groups of mice.
  • the mean clinical score of the mice in the control group is zero: the vehicle therefore does not induce any inflammation of the joint.
  • Treatment of the mice with dexamethasone brings the clinical score back to values close to those of the control group.
  • the clinical score of mice treated with KBxN increases until the 6 th day after which it reaches a plateau, which indicates distress and severe inflammation in mice.
  • Treatment with NMN makes it possible to reduce the clinical score significantly from the 5 th day. The reduction in the clinical score is increasing from 8 th day of treatment. Therefore, the administration of NMN significantly reduces the inflammation of the joints in this model of rheumatoid arthritis.
  • the paw of the mouse treated with NMN has a volume similar to that of the mouse treated with the vehicle: the NMN is therefore effective in treating the inflammation induced by the injection of K / BxN serum and much better tolerated by mice than conventional dexamethasone treatment.
  • NMN NMN
  • NMN its pharmaceutically acceptable derivatives or its pharmaceutically acceptable salts, as well as the compositions comprising them can therefore be used successfully and safely to treat and prevent rheumatoid arthritis.
  • the present invention therefore makes it possible to find a therapeutic alternative to conventional treatments for rheumatoid arthritis, or at the very least to provide a therapeutic complement to conventional treatments in order to reduce their frequency of use and their dosage. Because of the harmlessness of NMN, of its pharmaceutically acceptable derivatives or of its pharmaceutically acceptable salts, as well as of the compositions comprising it, the present invention makes it possible to treat and / or prevent rheumatoid arthritis without inducing the side effects caused by the treatments. conventional.
