This open-label, non-randomized study will assess the mass balance, metabolism, routes and rates of elimination as well as efficacy and safety of RO5185426 (RG7204; PLEXXIKON; PLX4032) in previously treated or untreated patients with metastatic melanoma. Patients will receive continuous twice daily oral treatment with RO5185426. On Day 15, a 14C-labeled dose will be administered. Anticipated time on study treatment is until disease progression occurs.

Primary Outcome Measures:
  • Pharmacokinetics: Mass balance, metabolism, routes and rates of elimination of 14C-labeled RO5185426 [ Time Frame: Day 14 to Day 36 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and tolerability: Adverse events, laboratory parameters, ECG [ Time Frame: from baseline to disease progression, withdrawal from study or death of any cause ] [ Designated as safety issue: No ]
  • Efficacy: Best Overall Response Rate (ORR): tumor assessments by CT/MRI/bone scan, according to RECIST criteria [ Time Frame: from baseline to disease progression, withdrawal from study or death of any cause ] [ Designated as safety issue: No ]
  • Overall Survival [ Time Frame: from baseline to death of any cause ] [ Designated as safety issue: No ]
