Adjuvant sorafenib for hepatocellular carcinoma after resection or ablation (STORM): a phase 3, randomised, double-blind, placebo-controlled trial.

BACKGROUND: There is no standard of care for adjuvant therapy for patients with hepatocellular carcinoma. This trial was designed to assess the efficacy and safety of sorafenib versus placebo as adjuvant therapy in patients with hepatocellular carcinoma after surgical resection or local ablation. METHODS: We undertook this phase 3, double-blind, placebo-controlled study of patients with hepatocellular carcinoma with a complete radiological response after surgical resection (n=900) or local ablation (n=214) in 202 sites (hospitals and research centres) in 28 countries. Patients were randomly assigned (1:1) to receive 400 mg oral sorafenib or placebo twice a day, for a maximum of 4 years, according to a block randomisation scheme (block size of four) using an interactive voice-response system. Patients were stratified by curative treatment, geography, Child-Pugh status, and recurrence risk. The primary outcome was recurrence-free survival assessed after database cut-off on Nov 29, 2013. We analysed efficacy in the intention-to-treat population and safety in randomly assigned patients receiving at least one study dose. The final analysis is reported. This study is registered with ClinicalTrials.gov, number NCT00692770. FINDINGS: We screened 1602 patients between Aug 15, 2008, and Nov 17, 2010, and randomly assigned 1114 patients. Of 556 patients in the sorafenib group, 553 (>99%) received the study treatment and 471 (85%) terminated treatment. Of 558 patients in the placebo group, 554 (99%) received the study treatment and 447 (80%) terminated treatment. Median duration of treatment and mean daily dose were 12·5 months (IQR 2·6-35·8) and 577 mg per day (SD 212·8) for sorafenib, compared with 22·2 months (8·1-38·8) and 778·0 mg per day (79·8) for placebo. Dose modification was reported for 497 (89%) of 559 patients in the sorafenib group and 206 (38%) of 548 patients in the placebo group. At final analysis, 464 recurrence-free survival events had occurred (270 in the placebo group and 194 in the sorafenib group). Median follow-up for recurrence-free survival was 8·5 months (IQR 2·9-19·5) in the sorafenib group and 8·4 months (2·9-19·8) in the placebo group. We noted no difference in median recurrence-free survival between the two groups (33·3 months in the sorafenib group vs 33·7 months in the placebo group; hazard ratio [HR] 0·940; 95% CI 0·780-1·134; one-sided p=0·26). The most common grade 3 or 4 adverse events were hand-foot skin reaction (154 [28%] of 559 patients in the sorafenib group vs four [<1%] of 548 patients in the placebo group) and diarrhoea (36 [6%] vs five [<1%] in the placebo group). Sorafenib-related serious adverse events included hand-foot skin reaction (ten [2%]), abnormal hepatic function (four [<1%]), and fatigue (three [<1%]). There were four (<1%) drug-related deaths in the sorafenib group and two (<1%) in the placebo group. INTERPRETATION: Our data indicate that sorafenib is not an effective intervention in the adjuvant setting for hepatocellular carcinoma following resection or ablation.

Eficácia e Segurança de Regorafenibe em Pacientes com Características de Bom Prognóstico no Tratamento do Câncer Colorretal Metastático: Análise de Subgrupo do Estudo CORRECT / Efficacy and Safety of Regorafenib in Patients with Characteristics of Good Prognosis in the Treatment of Metastatic Colorectal Cancer: Subgroup Analysis of CORRECT Study / Eficacia y Seguridad de Regorafenib en Pacientes con Características de Buen Pronóstico en Tratamiento del Cáncer Colorrectal Metastásico: Análisis de Subgrupo del Estudio CORRECT

Introdução: O câncer colorretal (CCR) é o segundo mais incidente e, quando metastático, apresenta taxa de sobrevida de 14% em cinco anos. Regorafenibe é um inibidor de tirosina-quinase (ITQ) aprovado para CCR metastático (CCRm) com aumento comprovado de sobrevida global (SG). Objetivo: Explorar resultados de eficácia e segurança de regorafenibe em pacientes com CCRm e características de bom prognóstico (CBP). Método: Análise de subgrupo do estudo CORRECT, com participantes divididos de acordo com CBP, seguindo os critérios: Eastern Cooperative Oncology Group (ECOG) 0, tempo de doença metastática maior que 18 meses, até três sítios metastáticos e ausência de metástase hepática. Eficácia comparada com teste de log-rank estratificado e hazad ratios (HR) calculados com o modelo de Cox. Resultados: Dos 760 participantes randomizados, 292 (34,5%) apresentavam CBP; 185 (63,4%) receberam regorafenibe; 107 (35,6%), placebo. Para o grupo CBP, a mediana SG foi 10,9 meses (IC95%:8,8-12,3) para regorafenibe e 7,3 meses (IC95%:5,6-9,1) para placebo, com 39% de redução no risco de morte (HR 0,61; IC95%:0,43-0,88; p=0,0069). A mediana de sobrevida livre de progressão (SLP) foi de 3,5 meses (IC95%:3,0-3,9) versus 1,8 mês (IC95%:1,7-1,8) respectivamente, com 61% de redução no risco de progressão da doença ou morte (HR 0,39; IC95%:0,30-0,52; p<0,0001). Os eventos adversos graus 3 e 4 foram mais frequentes para regorafenibe. Após definição de valor basal para escores de qualidade de vida (EQ-5D), estes decaíram menos para regorafenibe comparados com placebo (0,687 versus 0,592) com diferença significativa de 0,09. Conclusão: Pacientes com CBP que receberam regorafenibe melhoraram SG e SLP com menor deterioração da qualidade de vida comparado com placebo

Introduction: Colorectal cancer (CRC) is the second most common and when metastatic, it has a five-year survival rate of 14%. Regorafenib is an approved TKI for metastatic colorectal cancer (mCRC) with a proven increase in overall survival (OS). Objective: To investigate the efficacy and safety results of regorafenib in patients with mCRC and good prognostic characteristics (GPC). Method: Subgroup analysis of the CORRECT study, with participants divided according to GPC, following the criteria: Eastern Cooperative Oncology Group (ECOG) 0, duration of metastatic disease greater than 18 months, up to three metastatic sites and absence of liver metastasis. Efficacy compared with stratified log-rank test and hazard ratios (HR) calculated with the Cox model. Results: Of the 760 participants randomized, 292 (34.5%) had GPC; 185 (63.4%) received regorafenib; and 107 (35.6%) received placebo. For the GPC group, the median OS was 10.9 months (95%CI:8.8-12.3) for regorafenib and 7.3 months (95%CI:5.6-9.1) for placebo, with 39% of reduction of the risk of death (HR 0.61; 95% CI:0.43-0.88; p=0.0069). The median progression-free survival (PFS) was 3.5 months (95%CI:3.0-3.9) versus 1.8 months (95%CI:1.7-1.8) respectively, with 61% of reduced risk of disease progression or death (HR 0.39; 95%CI:0.30-0.52; p<0.0001). Grade 3 and 4 adverse events were more frequent for regorafenib. After setting baseline for quality of life scores (EQ-5D), these declined less for regorafenib compared to placebo (0.687 versus 0.592) with a significant difference of 0.09. Conclusion:GPC patients who received regorafenib improved OS and PFS with less deterioration of quality-of-life compared to placebo

Eficacia comparada con la prueba de log-rank estratificada y hazad ratios (HR) calculados con el modelo de Cox.Resultados: De los 760 participantes aleatorios, 292 (34,5%) tenían CBP; 185 (63,4%) recibieron regorafenib; 107 (35,6%) recibieron placebo. Para el grupo de CBP, la mediana de SG fue de 10,9 meses (IC95%:8,8-12,3) para regorafenib y de 7,3 meses (IC95%:5,6-9,1) para placebo, con una reducción del riesgo de muerte del 39% (HR 0,61; IC95%:0,43-0,88; p=0,0069). La mediana de supervivencia libre de progresión (PFS) fue de 3,5 meses (IC95%:3,0-3,9) frente a 1,8 meses (IC95%:1,7-1,8) respectivamente, con un 61% de riesgo reducido de progresión de la enfermedad o muerte (HR 0,39; IC95%:0,30-0,52; p<0,0001). Los eventos adversos de grado 3 y 4 fueron más frecuentes con regorafenib. Después de establecer la línea de base para las puntuaciones de calidad de vida (EQ-5D), estas disminuyeron menos con regorafenib en comparación con placebo (0,687 frente a 0,592) con una diferencia significativa de 0,09.
