Teriflunomide Concentrations in Cerebrospinal Fluid and Plasma in Patients with Multiple Sclerosis: A Pharmacokinetic Study.
Trial report in CNS drugs, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTeriflunomide is a disease modifying treatment (DMT) approved for relapsing-remitting multiple sclerosis (RRMS) in adults and children. It reduces lymphocyte proliferation by inhibiting the mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) and thereby the pyrimidine synthesis. Although most DMTs in multiple sclerosis (MS) modulate or inhibit the immune system in the periphery, the efficacy may improve if the agent also targets immune activity within the central nervous system (CNS), acts as a neuro-protective and enhances neuro-regeneration. The objective of this study was to determine the passage of teriflunomide over the blood-cerebrospinal fluid barrier (BCSFB).
methodsPlasma and cerebrospinal fluid (CSF) teriflunomide concentrations were determined at steady state in 12 patients with RRMS, treated with oral teriflunomide 14 mg once daily. Included patients were all clinically stable without relapse or disability worsening within 6 months prior from baseline and were on no other immune modulating or immunosuppressive drugs.
resultsThe mean teriflunomide concentrations in plasma and CSF were 38775 (SEM ± 7256) ng/mL and 68 (SEM ± 15) ng/mL, respectively. The passage over the BCSFB was 0.17 % (SEM ± 0.01). While no correlation was found between the function of the BCSFB assessed with the albumin ratio and the CSF teriflunomide concentration, the CSF and plasma teriflunomide concentrations were highly correlated (r
conclusionsFurther studies are warranted to determine if the obtained CSF teriflunomide concentration reflects that in the CNS and is able to influence inflammatory and degenerative processes within the CNS.
