Pembrolizumab plus axitinib and nivolumab plus ipilimumab as first-line treatments of advanced intermediate- or poor-risk renal-cell carcinoma: a number needed to treat analysis from the Brazilian private perspective.

BACKGROUND: Considering clinical benefits of new combination therapies for metastatic renal-cell carcinoma (mRCC), this study aims to calculate the number needed to treat (NTT) and the cost of preventing an event (COPE) for pembrolizumab plus axitinib (P + A), and nivolumab plus ipilimumab (N + I) as first-line treatments, from the Brazilian private perspective. METHODS: Overall survival (OS) and progression-free survival (PFS) data for intermediate- and poor-risk groups were obtained from KEYNOTE-426 and CHECKMATE-214 trials for P + A and N + I, respectively, versus sunitinib as mRCC first-line treatment. RESULTS: Considering a 12-month time horizon, 6 patients should be treated with P + A to prevent one death with sunitinib use, resulting in a COPE of 3,773,865 BRL. Using N + I, NNT for 12-month OS rate was 13 compared to sunitinib, with a COPE of 6,357,965 BRL. Regarding PFS data, NNT was also 6 when comparing P + A versus sunitinib, with an estimated COPE of 3,773,865 BRL. Estimated NNT was 20 comparing N + I and sunitinib, resulting in a COPE of 10,172,744 BRL. Cost differences between two treatment options, reached more than 6 million BRL for PFS, and 2 million BRL for OS. CONCLUSION: At the 12-month landmark, P + A suggests better economic scenario versus N + I as first-line mRCC treatment option for intermediate- and poor-risk groups, through an indirect comparison using sunitinib as a common comparator.

Renal cancer is the 13th most frequent neoplasm in the world. From 2010 to 2014, renal cancer accounted for 1.43% of cancer deaths in Brazil. The treatment of choice for metastatic renal cancer is tyrosine kinase inhibitors (TKI) sunitinib and pazopanib. This article assesses cost-effectiveness between pazopanib and sunitinib in the treatment of metastatic renal cancer. A cost-effectiveness study was performed from the perspective of a federal hospital under the Brazilian Unified National Health System (SUS). TKI effectiveness and safety outcomes were applied to the decision tree model. Clinical data were extracted from patient charts, and direct costs were consulted from official Ministry of Health sources. The cost of 10 months of treatment, including the costs of the TKI, procedures and management of adverse events, was BRL 98,677.19 for pazopanib and BRL 155,227.11 for sunitinib. The drugs displayed statistically equivalent effectiveness and statistically different safety outcomes, with pazopanib displaying better results. In this setting, pazopanib is the dominant technology when the treatment costs are analyzed together with the costs of managing adverse events.

O câncer renal é a 13ª neoplasia mais frequente no mundo. Entre 2012 e 2016, representou 1,48% das mortes por câncer no Brasil. A terapia de escolha para o tratamento de câncer renal metastático são os inibidores de tirosina quinase (ITK), sunitinibe e pazopanibe. Este artigo avalia o custo-efetividade do pazopanibe comparado ao sunitinibe no tratamento de câncer renal metastático. Foi realizada uma análise de custo-efetividade sob a perspectiva de um hospital federal do Sistema Único de Saúde. No modelo de árvore de decisão foram aplicados os desfechos de efetividade e segurança dos ITK. Os dados clínicos foram extraídos de prontuários e os custos diretos consultados em fontes oficiais do Ministério da Saúde. O custo de 10 meses de tratamento, englobando o valor dos ITK, procedimentos e manejo de eventos adversos, foi de R$ 98.677,19 para o pazopanibe e R$ 155.227,11 para o sunitinibe. Os medicamentos apresentaram efetividade estatisticamente equivalente e diferença estatisticamente significativa para o desfecho de segurança, no qual o pazopanibe obteve o melhor resultado. O pazopanibe, nesse contexto, é a tecnologia dominante quando os custos de tratamento são associados aos de manejo de eventos adversos.

Economic evaluation of sunitinib versus pazopanib and best supportive care for the treatment of metastatic renal cell carcinoma in Chile: cost-effectiveness analysis and a mixed treatment comparison.

Background: Sunitinib and Pazopanib are two metastatic renal cell carcinoma (MRCC) treatment alternatives, however the health system in Chile does not consider coverage for any. The cost-effectiveness versus relevant comparator was assessed to support evidence-based decision making. Methods: A four health states Markov model was built: first, second line treatments, BSC and death. Benefits were measured in QALYs, and efficacy estimates were obtained from an indirect treatment comparison. A 10-year time horizon and a 3% undifferentiated discount rate were considered. Deterministic and probabilistic sensitivity analyses were performed. Results: The costs of treating MRCC with Sunitinib were higher than Pazopanib and BSC. When comparing Sunitinib versus Pazopanib, the incremental benefit is small favoring Sunitinib (0.03 QALYs). The base case scenario shows an average ICER of PA versus BSC of US$62,327.11/QALY and of US$85,885/QALY for Sunitinib versus Pazopanib. The ICER was most sensitive to the OS relative to BSC, where evidence was associated to important bias. Conclusions: Sunitinib or Pazopanib can be considered cost-effective if a 3 GDP per-capita threshold is assumed. The decision between SU or PA is highly sensitive to the price of the drugs, rather than the outcomes. Therefore, the decision might be made based on cost-minimization exercise.
