Frequently asked questions about Leflunomide

What is leflunomide used for?

Leflunomide is a small molecule immunology drug studied for rheumatoid arthritis and systemic lupus erythematosus. It has been evaluated in a Phase 3 trial in early rheumatoid arthritis and a Phase 2 trial in SLE. It is developed by Sanofi.

What does leflunomide target?

Leflunomide targets DHODH, dihydroorotate dehydrogenase, and acts as an inhibitor of this enzyme. DHODH is involved in pyrimidine synthesis, and inhibiting it is the drug's mechanism of action in immunology indications such as rheumatoid arthritis and SLE.

Who makes leflunomide?

Leflunomide is developed by Sanofi, which trades under the ticker SNY. Sanofi is the company associated with the clinical development of leflunomide in rheumatoid arthritis and systemic lupus erythematosus.

What phase is leflunomide in?

Leflunomide has been studied in Phase 3 for rheumatoid arthritis and Phase 2 for systemic lupus erythematosus. The Phase 3 rheumatoid arthritis trial is completed, and the Phase 2 SLE trial is also completed. It remains an investigational agent in these clinical programs.

What clinical trials is leflunomide in?

Leflunomide has been evaluated in NCT00596206, a completed Phase 3 trial in early rheumatoid arthritis with 124 participants across Czechia, Italy, Portugal, Romania, and South Korea, and NCT00637819, a completed Phase 2 trial in systemic lupus erythematosus with 27 participants in Hong Kong.

Is leflunomide FDA approved?

Leflunomide is an investigational small molecule in clinical development for rheumatoid arthritis and systemic lupus erythematosus, with completed Phase 3 and Phase 2 trials. The available information does not indicate FDA approval for these indications.
