The study will also evaluate efficacy and safety of RO5185426. On day 1, patients will receive the drug cocktail. On days 6 to 19, patients will receive RO5185426 twice daily. On day 20, patients will receive RO5185426 and the drug cocktail and on days 21 to 25, patients will receive RO5185426. Assessments will be made at regular intervals during the dosing periods and at follow-up. Patients may continue on study treatment (RO5185426) until the development of progressive disease or unacceptable toxicity. Target sample size \<50.
