Original Abstract of the Article

Main Research Findings

Teriflunomide is an oral immunomodulatory agent approved in the United States for the treatment of relapsing multiple sclerosis (RMS). A study investigating the effects of teriflunomide on neurophysiological deficits in descending spinal cord motor tracts during experimental autoimmune encephalomyelitis (EAE; a model of multiple sclerosis) found that both prophylactic and therapeutic teriflunomide treatment significantly reduced maximum EAE disease scores compared with vehicle-treated rats. 5 Additionally, electrophysiological recordings demonstrated that both teriflunomide treatment regimens prevented a delay in wave-form latency and a decrease in wave-form amplitude compared with that observed in vehicle-treated animals. Both treatment regimens also significantly reduced axonal loss. This suggests that teriflunomide can prevent the deficits observed in this animal model in descending spinal cord motor tracts.

Another study investigating the effects of teriflunomide on lymphocyte subpopulations in human peripheral blood mononuclear cells in vitro found that teriflunomide had little to no impact on lymphocyte activation but exerted significant dose-dependent inhibition of T- and B-cell proliferation. 4 This inhibition was uridine-reversible (DHODH-dependent). Furthermore, teriflunomide significantly decreased the release of several pro-inflammatory cytokines from activated monocytes in a DHODH-independent fashion. The results of this study suggest that teriflunomide acts on multiple immune cell types and processes via DHODH-dependent and independent mechanisms.

Teriflunomide is a disease-modifying therapy (DMT) for relapsing-remitting multiple sclerosis (RRMS). 16 While its mechanism of action is thought to be related to the inhibition of dihydroorotate dehydrogenase (DHODH), a key mitochondrial enzyme in the de novo pyrimidine synthesis pathway required by rapidly dividing lymphocytes, more research is needed to understand how the adaptive and innate immune cell subsets are affected by the treatment in patients with MS.

Benefits and Risks

Benefit Summary

Research suggests that teriflunomide may offer several benefits in the treatment of multiple sclerosis. 5 , 3 , 16

  • May reduce the maximum EAE disease score.
  • May prevent neurophysiological deficits in descending spinal cord motor tracts.
  • May reduce axonal loss.
  • May inhibit the proliferation of stimulated lymphocytes.
  • May inhibit the proliferation of T cells and B cells.
  • May decrease the release of pro-inflammatory cytokines.
  • May preferentially inhibit the proliferation of high-affinity autoreactive T cell clones.
  • May correct metabolic disturbances in T cells.

Risk Summary

Teriflunomide may be associated with some risks in the treatment of multiple sclerosis. 4 , 18

  • May cause cytotoxicity.
  • May cause side effects such as subacute cutaneous lupus erythematosus (SCLE).

Comparison of Studies

Commonalities of Studies

Multiple studies have investigated the effectiveness and safety of teriflunomide in the treatment of multiple sclerosis, suggesting that teriflunomide may be an effective treatment option for patients with relapsing-remitting multiple sclerosis.

Differences of Studies

The studies on teriflunomide have explored different aspects of its mechanism of action, effectiveness, and safety. For example, 5 focused on the effects of teriflunomide on descending spinal cord motor tracts in animal models, while 4 investigated the effects of teriflunomide on lymphocyte subpopulations in vitro. 3 explored the effect of teriflunomide on T cell mitochondrial respiration.

Consistency and Contradictions in Results

While numerous studies suggest that teriflunomide may be an effective and safe treatment for multiple sclerosis, the precise mechanism of action, effectiveness, and safety profile still require further investigation. More research is needed to address these remaining questions.

Practical Implications

Teriflunomide appears to be a clinically effective treatment option for multiple sclerosis. However, as with any medication, it is crucial to follow your doctor's instructions carefully and discuss your medical history and any other medications you may be taking before starting treatment with teriflunomide.

Limitations of Current Research

Research on teriflunomide is ongoing, and further investigation is needed to solidify its effectiveness and safety. Teriflunomide is a relatively new medication for treating multiple sclerosis, and long-term effects remain to be fully understood. More research is needed to address these limitations.

Future Research Directions

Future research on teriflunomide should consider the following areas:

  • Elucidating the specific mechanism of action of teriflunomide.
  • Investigating the long-term effects of teriflunomide.
  • Establishing the optimal dosage and administration method for teriflunomide.
  • Exploring ways to mitigate the side effects of teriflunomide.

Conclusion

Teriflunomide shows promise as a potentially effective and safe treatment for multiple sclerosis. However, it's important to remember that every individual responds differently to medication, and it's essential to discuss your medical history and any concerns with your doctor before starting any new treatment. Further research will continue to provide a deeper understanding of the effectiveness, safety, and mechanism of action of teriflunomide.
