Arm Intervention/treatment
Experimental: Arm 1
Pazopanib monotherapy or in combination with lapatinib
Drug: pazopanib
Pazopanib oral tablet

Drug: Lapatinib
Lapatinib oral tablet

Primary Outcome Measures :
  1. Safety and tolerability [ Time Frame: before and after taking the study medications ]
    The safety and tolerability endpoints will consist of the evaluation of adverse events (AEs), and changes in vital signs and laboratory values.

Secondary Outcome Measures :
  1. Pharmacokinetics [ Time Frame: over a 24 hour period ]
    The pharmacokinetic parameters AUC0-24, AUC0-inf (Day 1 only), Cmax, tmax, and t1/2 of pazopanib and its four metabolites. To determine if target trough plasma concentration of pazopanib of 20,000 ng/ml is achieved.

  2. Tumor response [ Time Frame: 9 weeks ]
    Assessments of tumor response will be obtained every 9 weeks and will be recorded as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD).
