Summary description of the study

Leflunomide has been used for many years to treat rheumatoid arthritis. Several studies in tumor cells and mice have shown that leflunomide has growth-inhibitory effects on various tumors. In a recent study, leflunomide specifically destroyed MEN1-deficient cells, prevented the onset of pancreatic tumors in mice, and led to tumor regression/stabilization in three MEN1 patients with advanced aggressive pancreatic tumors. Accordingly, leflunomide could be used as a new treatment option for patients with known MEN1 mutation. The aim of this study is therefore to investigate the antitumor effect of leflunomide treatment on MEN1-associated tumors in patients with known MEN1 syndrome.

Intervention under investigation

Treatment with leflunomide 20 mg once daily for 6 months

(BASEC)

Disease under investigation

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited disorder caused by mutations in the tumor suppressor gene MEN1 with the corresponding gene product Menin. MEN1 is characterized by the occurrence of parathyroid, pancreatic, and pituitary tumors that can release excessive amounts of hormones. To date, there is no prophylactic treatment to prevent tumor development in this hereditary disease.

Criteria for participation in trial
Adults (≥ 18 years) with MEN1 mutation and at least 1 associated tumor lesion OR hormonal syndrome (BASEC)

Exclusion criteria
- uncontrolled arterial hypertension - impaired kidney or liver function - active hepatitis B or C or severe immunosuppression, e.g. AIDS (BASEC)
