Arm Intervention/treatment
Experimental: RO5424802 Drug: RO5424802
Single oral doses followed by IV or oral administration of a 14C-labeled tracer

Primary Outcome Measures :
  1. Elimination: Amount of drug excreted in urine/feces over the study period [ Time Frame: Days 11 to 15 ]
  2. Pharmacokinetics: Bioavailability (Area under the plasma concentration-time curve [AUC]) after administration of RO5424802 [ Time Frame: Days 1 to 25 ]

Secondary Outcome Measures :
  1. Safety: Incidence of adverse events [ Time Frame: Days 1 to 25 ]
  2. Pharmacokinetics: Metabolite identification in plasma, urine, and feces. [ Time Frame: Days 11 to 25 ]
