Анакинра: Қолданылуы мен емдеу мүмкіндіктері

Pharmaceutical drug

Anakinra, sold under the brand name Kineret, is a biopharmaceutical medication used to treat rheumatoid arthritis, cryopyrin associated periodic syndromes, familial Mediterranean fever, and Still's disease. Anakinra is administered by subcutaneous injection. It is administered subcutaneously to patients diagnosed with a cryopyrin associated periodic syndrome, including neonatal onset multisystem inflammatory disease. Its response rate is such that it has been suggested that "Treatment failures should lead to reconsider the diagnosis." Off label, it is used to treat systemic juvenile idiopathic arthritis (SJIA), gout, calcium pyrophosphate deposition (CPPD), Behçet's disease, ankylosing spondylitis, uveitis, and other auto inflammatory syndromes. In December 2021, the European Medicines Agency authorized the use of anakinra "to treat COVID 19 in adults with pneumonia requiring supplemental oxygen (low or high flow oxygen) and who are at risk of developing severe respiratory failure, as determined by blood levels of a protein called suPAR (soluble urokinase plasminogen activator receptor) of at least 6 ng per ml." In November 2022, the United States FDA approved its use under an emergency use authorization "for the treatment of COVID 19 in hospitalized adults with pneumonia requiring supplemental oxygen (low or high flow oxygen) who are at risk of progressing to severe respiratory failure and likely to have an elevated plasma soluble urokinase plasminogen activator receptor (suPAR)."

It was not tested in pregnant women, but appeared to be safe in animal studies. and a Clinical Commissioning Policy: Anakinra/tocilizumab for the treatment of Adult Onset Still's Disease refractory to second line therapy (adults), allowing Anakinra to be commissioned for adult onset Still's disease "as a third line treatment where patients are refractory to steroid sparing effect DMARDs". In December 2020, Anakinra was approved by the US Food and Drug Administration for the treatment of deficiency of the interleukin 1–receptor antagonist (DIRA), a rare autoinflammatory disease of infancy. In 2021, it was announced that the Ministry of Health of the Russian Federation had approved the use of Anakinra for the treatment of CAPS. In October 2021, NHS England published Clinical Commissioning Policy: Anakinra for Haemophagocytic Lymphohistiocytosis (HLH) for adults and children in all ages, allowing Anakinra to be used in the treatment of HLH.

Anakinra effectively treated meningitis caused by a rare genetic mutation in the gene NALP3 in a 67 year old man enrolled in the Undiagnosed Diseases Network. Researchers at Johns Hopkins University announced in 2019 that anakinra given to pregnant mice with Zika virus had reduced fetal deaths and birth defects. In November 2019, researchers at the University of Manchester reported that Anakinra might have a use in preventing breast cancer from spreading to the bones. In 2021, it was reported that Anakinra appeared to reduce the neuropathic pain experienced by patients undergoing chemotherapy with vincristine, saying that "repurposing anakinra may be an effective co treatment strategy to prevent vincristine induced peripheral neuropathy". A review published in 2022 found that "Anakinra appears to show efficacy for numerous dermatologic conditions, with the strongest evidence for hidradenitis suppurativa, Behçet's disease, Muckle–Wells syndrome, and SAPHO syndrome." and concluded that "Overall, anakinra appears to be a promising option in the treatment of numerous dermatologic inflammatory conditions refractory to first line therapies, but further and higher quality data is needed to clarify its therapeutic role." In 2023, researchers at Columbia University explored the effect of Anakinra on the ageing of Hematopoietic stem cells in mice. They concluded "that targeting IL 1 as a key mediator of niche inflammation is a tractable strategy to improve blood production during ageing" and were reported to have said "that their findings could pave the way for science to delay aging and even lengthen the lifespan of humans". A 2023 preliminary study on the use of Anakinra in the treatment of endometriosis concluded that "there is justification for a larger study" and that "Anakinra may be a particularly impactful option for women desiring fertility."

Anakinra is undergoing multiple clinical trials to treat COVID 19 patients, by targeting mechanisms in patients with hyperinflammation. In 2021 a review and meta analysis of 9 studies involving 1,119 cases concluded that "Available evidence shows that treatment with anakinra reduces both the need for invasive mechanical ventilation and mortality risk of hospitalized non intubated patients with COVID 19 without increasing the risk of adverse events." as of 2021, the European Medicines Agency (EMA) is evaluating an application to extend the use of anakinra to include treatment of COVID 19 in adults with pneumonia who are at risk of developing severe respiratory failure (inability of the lungs to work properly). According to study results published in September 2021 in Nature Medicine, hospitalized COVID 19 patients at increased risk for respiratory failure showed significant improvement after treatment with Anakinra.
