Sunitinib malate is an oral multitargeted tyrosine kinase inhibitor exhibiting antiangiogenic activity. Sunitinib demonstrated improved outcomes in comparison to interferon-α in a large phase III study of treatment naïve patients with metastatic renal cell carcinoma. Maintaining patients on sunitinib treatment is essential for a sustained disease control as higher exposure to sunitinib has been associated with an improved overall response rate, progression-free survival and overall survival. Various studies have compared the outcomes of patients undergoing sunitinib therapy based on modifications from their standard dose and schedule. Several studies have shown that switching to an alternate schedule with more frequent dose interruptions without affecting dose density over a 6-week cycle is associated with improved outcomes and increased tolerability.
苹果酸舒尼替尼是一种口服多靶点酪氨酸激酶抑制剂,具有抗血管生成活性。在一项针对初治转移性肾细胞癌患者的大型III期研究中,舒尼替尼与α干扰素相比显示出更好的疗效。维持患者接受舒尼替尼治疗对于持续控制疾病至关重要,因为更高的舒尼替尼暴露量与改善的总缓解率、无进展生存期和总生存期相关。多项研究根据标准剂量和给药方案的调整比较了接受舒尼替尼治疗患者的疗效。几项研究表明,在6周周期内改为更频繁剂量中断但不影响剂量密度的替代给药方案与改善疗效和提高耐受性相关。
