Name Time Method Main Objective: Evaluate the safety and tolerability of oral cladribine (cladribine tablets)when added on to Rebif. Evaluate the efficacy of oral cladribine (cladribine tablets) when added on to Rebif compared to placebo when added on to Rebif in MS subjects with active disease;Secondary Objective: Assess the efficacy in MS subjects with active disease of 2 cladribine tablet dose levels as an add-on to a fixed dose of Rebif (44 mcg tiw) compared to placebo as an add-on to a fixed dose of Rebif on: - lesion activity (as measured by MRI) - qualifying relapse rate - progression of disability;Primary end point(s): The primary safety endpoints will consist of safety and tolerability parameters measured over a period of 96 weeks
