Treatment of Renal Angiomyolipomas in Tuberous Sclerosis by Beta-blockers

Phase 2
Completed
Conditions
Renal Angiomyolipomas
Tuberous Sclerosis

Registration Number
NCT02104011
Lead Sponsor
University Hospital, Bordeaux
Brief Summary

Treatment of angiomyolipomas is based on invasive techniques such as surgery or embolization. Development of anti-angiogenic therapies is a major and growing field of research in hypervascularized tumors. Angiomyolipomas have been shown to regress after prolonged treatment with mTOR inhibitors (Sirolimus), but with a large proportion of secondary effects. We showed recently that beta-blockers were able to induce regression of infantile hemagiomas. Consequently, we looked for and found, histologically, in a few cases of angiomyolipomas the presence of beta2 receptors.

The aim of the study is to estimate if beta-blockers could induce regression or stabilization of renal angiomyolipomas in tuberous sclerosis in a pilot study.

Primary Outcome Measures
NameTimeMethod
Evolution of angiomyolipomas volume6 months and 1 year after inclusion

Stabilization or even regression of angiomyolipomas volume after 6 months and 1 year of treatment with a quantification of the vascular component.

Secondary Outcome Measures
NameTimeMethod
Renal function evolution6 months and 1 year after inclusion

Improvement of renal function after 6 months and 1 year of treatment

Effect on the potential haemorraghic transformation6 months and 1 year after inclusion

Haemorraghic transformation of angiomyolipomas is diagnosed by Scanner or MRI.
