NCT00683124

Brief Summary

The major clinical problems in patients with Marfan Syndrome (MFS) are aortic root dilation (ARD), dissection and rupture. Although the available treatments (beta-blockers, BBs) improve the evolution of the disease, they do not protect MFS patients from progression of ARD and dissection. A key molecule that negatively influences cell growth, differentiation, survival and death in MFS is TGFb which is antagonised by existing drugs employed in the clinical practice, the Angiotensin II receptor blockers (ARB).

Study Arms (3)

Losartan

EXPERIMENTAL

Losartan administered as maximal tolerated dosage, not to exceed the maximal theorical dosage of 100 mg/day for adults and 1,6 mg/kg/die for children minor than 16 years.

Drug: Losartan

Nebivolol

EXPERIMENTAL

Nebivolol administered as maximal tolerated dosage, not to exceed the maximal theorical dosage of 10 mg/day for adults and 0,16 mg/kg/die for children minor than 16 years.

Drug: Nebivolol

Losartan+Nebivolol

EXPERIMENTAL

Losartan administered as maximal tolerated dosage, not to exceed the maximal theorical dosage of 100 mg/day for adults and 1,6 mg/kg/die for children minor than 16 years.

Drug: Losartan and nebivolol

Interventions

Nebivolol is administered orally as pills. It is given preferentially once a day in the morning or, if not well tolerated because of hypotension, the total daily dosage is given in two administrations. Losartan is administered orally as pills. It is given preferentially once a day or, if not well tolerated because of hypotension, the total daily dosage is given in two administrations

Losartan+Nebivolol

Losartan is administered orally as pills. It is given preferentially once a day or, if not well tolerated because of hypotension, the total daily dosage is given in two administrations

You may not qualify if:

  • Prior aortic surgery and/or dissection
  • Aortic root diameter at the level of the sinuses of Valsalva 5 cm
  • Planned aortic surgery within 6 months of enrollment for a rate of ARD progression\>5 mm/year even in pts with ARD less than 5 cm
  • Clinical or molecular diagnosis of non-MFS connective tissue diseases sharing some features with MFS (Shprintzen-Goldberg syndrome or Loeys-Dietz syndromes)
  • Un-renounceable therapeutic (systemic hypertension, arrhythmia, ventricular dysfunction, valve regurgitation) use of drugs such as ACE inhibitors, BBs, or calcium-channel blockers
  • Known side-effects while taking an ARB or a BB
  • Intolerance to ARB that resulted in termination of therapy
  • Intolerance to BB that resulted in termination of therapy
  • Renal dysfunction (creatinine level more than upper limit of age-related normal values)
  • Diabetes mellitus
  • Pregnancy or planned pregnancy within 48 months of enrollment
  • Technical limitations for the imaging studies including poor acoustic windows with limits the accurate measurement of aortic root
