The serum and cerebrospinal fluid pharmacokinetics of anakinra after intravenous administration to non-human primates.

ABSTRACT: Anakinra improves the central nervous system manifestations of neonatal-onset multisystem inflammatory disease, which is mediated by IL-1beta oversecretion. The cerebrospinal fluid (CSF) penetration of the IL-1 receptor antagonist anakinra was studied in rhesus monkeys after intravenous doses of 3 and 10 mg/kg. Drug exposure (area under concentration-time curve) in CSF was 0.28% of that in serum. The average CSF concentration at 3 mg/kg was 1.8 ng/mL, which is 30-fold higher than endogenous CSF levels of IL-1Ra. The CSF penetration was not dose-dependent, indicating that the CSF penetration was not saturated in the 3 to 10 mg/kg dose range.

Project description:Neurologic manifestations are among the most frequently reported complications of COVID-19. However, given the paucity of tissue samples and highly infectious nature of the etiologic agent of COVID-19, we have limited information to understand the neuropathogenesis of COVID-19. Therefore to better understand the impact of COVID-19 in brain, we employed mass-spectrometry-based proteomics using data-independent acquisition mode (DIA) to investigate cerebrospinal fluid (CSF) proteins collected from two different non-human primates, Rhesus Macaque and African Green Monkeys for the neurologic effects of the infection. These monkeys exhibited minimal to mild pulmonary pathology but moderate to severe CNS pathology. Our results indicate that CSF proteome changes after infection resolution correspond with bronchial virus abundance during early infection and revealed substantial differences between the infected NHPs and their age-matched uninfected controls, suggesting these differences could reflect altered secretion of CNS factors in response to SARS-CoV-2-induced neuropathology. We also observed the infected animals to exhibit much scattered data distributions as compared to the tightly clustered corresponding controls which suggest the heterogeneity of the CSF proteome change and the host response to the viral infection. In addition, dysregulated CSF proteins were preferentially enriched in functional pathways associated with progressive neurodegenerative disorders, hemostasis and innate immune responses that could influence neuroinflammatory responses following COVID-19. Mapping dysregulated proteins to the Human Brain Protein Atlas found that these proteins tended to be enriched in brain regions that exhibit more frequent injury following COVID-19. It therefore appears reasonable to speculate that such CSF protein changes could serve as signatures for neurologic injury, identify important regulatory pathways in this process, and potentially reveal therapeutic targets to prevent or attenuate the development of neurologic injuries following COVID-19.
