Background:

Pazopanib HCl is a receptor tyrosine kinase inhibitor that targets multiple kinases, including VEGFR1, VEGFR2, VEGFR3, PDGFR, FGFR, c-Kit, and c-Fms, with IC50s 10nM, 30nM, 47nM, 84nM, 74nM, 140nM, and 146nM respectively [1-3]. Pazopanib inhibits both tumor growth and angiogenesis through suppressing these targets. In preclinical studies, it has shown anti-tumor activity against several human tumor xenografts, including renal, prostate, colon, lung, melanoma, head and neck, and breast cancer [4]. It also showed desirable pharmacokinetics and oral bioavailability in animal models [4].

Pazopanib has been approved for advanced/metastatic renal cell carcinoma and advanced soft tissue sarcomas by multiple regulatory administrations worldwide, including FDA, EMA, MHRA and TGA. In the clinical trial for soft tissue sarcomas, Pazopanib improved median progression-free survival (PFS) to 4.6 months compared to 1.6 months for patients receiving placebo [5]. In the trial for renal cell carcinoma, Pazopanib increased the median PFS from 4.2 monthe (placebo) to 9.2 months [5]. The most common adverse effect of Pazopanib were diarrhea, hypertension, hair color change, nausea, fatigue, anorexia, and vomiting [6].
