Tyrosine kinase inhibitors such as sunitinib and pazopanib are the mainstay of treatment of metastatic renal cell carcinoma (mRCC) in India. However, pembrolizumab and nivolumab have shown significant improvement in the median progression-free survival and overall survival among patients with mRCC. In this study, we aimed to determine the cost-effectiveness of the first-line treatment options for the patients with mRCC in India.
A Markov state-transition model was used to measure the lifetime costs and health outcomes associated with sunitinib, pazopanib, pembrolizumab/lenvatinib, and nivolumab/ipilimumab among patients with first-line mRCC. Incremental cost per quality-adjusted life-year (QALY) gained with a given treatment option was compared against the next best alternative and assessed for cost-effectiveness using a willingness to pay threshold of one-time per capita gross-domestic product of India. The parameter uncertainty was analyzed using the probabilistic sensitivity analysis.
We estimated the total lifetime cost per patient of ₹ 0.27 million ($3,706 US dollars [USD]), ₹ 0.35 million ($4,716 USD), ₹ 9.7 million ($131,858 USD), and ₹ 6.7 million ($90,481 USD) for the sunitinib, pazopanib, pembrolizumab/lenvatinib, and nivolumab/ipilimumab arms, respectively. Similarly, the mean QALYs lived per patient were 1.91, 1.86, 2.75, and 1.97, respectively. Sunitinib incurs an average cost of ₹ 143,269 ($1,939 USD) per QALY lived. Therefore, sunitinib at current reimbursement rates (₹ 10,000 per cycle) has a 94.6% probability of being cost-effective at a willingness to pay threshold of 1-time per capita gross-domestic product (₹ 168,300) in the Indian context.
Our findings support the current inclusion of sunitinib under India's publicly financed health insurance scheme.
舒尼替尼和帕唑帕尼等酪氨酸激酶抑制剂是印度转移性肾细胞癌(mRCC)治疗的主要方法。然而,派姆单抗和纳武单抗已显示出在 mRCC 患者的中位无进展生存期和总生存期方面的显著改善。在这项研究中,我们旨在确定印度 mRCC 患者一线治疗方案的成本效益。
使用马尔可夫状态转移模型来衡量舒尼替尼、帕唑帕尼、派姆单抗/仑伐替尼和纳武单抗/伊匹单抗一线治疗 mRCC 患者的终生成本和健康结果。使用印度人均国内生产总值(GDP)一次的支付意愿阈值,比较给定治疗方案的增量成本每获得一个质量调整生命年(QALY)与下一个最佳替代方案,并评估成本效益。使用概率敏感性分析对参数不确定性进行分析。
我们估计每位患者的总终生成本分别为舒尼替尼组 270 万卢比(3706 美元)、帕唑帕尼组 350 万卢比(4716 美元)、派姆单抗/仑伐替尼组 970 万卢比(131858 美元)和纳武单抗/伊匹单抗组 670 万卢比(90481 美元)。同样,每位患者的平均 QALY 分别为 1.91、1.86、2.75 和 1.97。舒尼替尼每 QALY 成本为 143269 卢比(1939 美元)。因此,按照目前的报销标准(每个周期 10000 卢比),在印度的背景下,在支付意愿阈值为 1 次人均 GDP(168300 卢比)时,舒尼替尼有 94.6%的概率具有成本效益。
我们的研究结果支持印度目前将舒尼替尼纳入公共资助的医疗保险计划。
