Detailed Description:

Based on an interim analysis from the phase II, 1160.113 and 1160.138 trials which suggested that the investigated dosing regimen did not achieve the desired results in this patient population, it was decided that from this point forward, patients will discontinue study medication and be followed up for a further six months.
