研究组 & 干预措施
pazopanib
For subjects > 18 years of age and subjects 16-17 years of age with a BSA ≥ 1.6 Pazopanib 800mg once daily will be started on Cycle 1 Day 1 and will be administered continuously for each 28-day cycle. Subjects may continue study treatment until they develop disease progression or unacceptable toxicity.
For subjects 16-17 years of age with a BSA < 1.6 m2, Pazopanib 600mg once daily will be started on Cycle 1 Day 1 and will be administered continuously for each 28-day cycle. Subjects may continue study treatment until they develop disease progression or unacceptable toxicity.

结局指标
主要结局
4-month Progression Free Survival (PFS) per RECIST version 1.1 guidelines
时间窗: 4 months from the beginning of study treatment
The primary objective of the study is to evaluate the 4-month PFS (with demonstrated increase in tumor doubling time) of eligible subjects treated with pazopanib according to RECIST version 1.1 guidelines. Tumor growth rate will be calculated by measuring growth at the specified intervals for the single, longest dimension of the tumor(s) (RECIST) and by calculating the area of the tumor(s), which will be the product of the longest dimension of the tumor(s) multiplied by its longest, perpendicular dimension (WHO). Progressive disease (PD) for target lesions is defined as at least a 20% increase in the sum of diameters of the target lesions taking as reference the smallest sum on study, and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression. PD for non-target lesions is defined as unequivocal appearance of one or more new malignant lesions. Unequivocal progression of existing non-target lesions.
次要结局
- 4-month PFS per WHO criteria(4 months from the beginning of study treatment)
- Pharmacokinetics evaluation(Day 1 of Cycles 2 and 3 (Approximately 5 and 7 weeks from the start of study treatment))
- Overall Survival (OS)(Cycle 1 Day 1 (start of study treatment) up to death or 60 months after the end of study treatment, whichever occurs first)
- PFS(Assessed at Week -4 and 3 to 5 days prior to study treatment, approximately 4 weeks from the start of study treatment and every 6 weeks thereafter until the patient progresses or 60 months from the end of treatment, whichever occurs first)
- Response rate per WHO criteria(Assessed at Week -4 and 3 to 5 days prior to study treatment, approximately 4 weeks from the start of study treatment and every 6 weeks thereafter until the patient progresses or 60 months from the end of treatment, whichever occurs first)
- Tumor growth kinetics(Assessed at Week -4 and 3 to 5 days prior to study treatment, approximately 4 weeks from the start of study treatment and every 6 weeks thereafter until the patient progresses or 60 months from the end of treatment, whichever occurs first)
- Response rate per RECIST version 1.1(Assessed at Week -4 and 3 to 5 days prior to study treatment, approximately 4 weeks from the start of study treatment and every 6 weeks thereafter until the patient progresses or 60 months from the end of treatment, whichever occurs first)
