Randomized Controlled Trial Comparative Study
Efficacy of Nivolumab plus Ipilimumab According to Number of IMDC Risk Factors in CheckMate 214.
In the randomized, open-label, phase 3 CheckMate 214 trial, nivolumab plus ipilimumab (nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 wk for four doses, then nivolumab 3 mg/kg every 2 wk) had superior efficacy over sunitinib (50 mg once daily, 4 wk on, 2 wk off) in patients with untreated International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) intermediate- or poor-risk advanced renal cell carcinoma; the benefits were sustained through extended follow-up. To better characterize the association between outcomes and IMDC risk in CheckMate 214, we completed a post hoc analysis (n = 1051) of efficacy by the number of IMDC risk factors. The investigator-assessed objective response rate (ORR), overall survival (OS), and investigator-assessed progression-free survival (PFS) according to Response Evaluation Criteria in Solid Tumors v1.1 were evaluated. ⋯ These results demonstrate the benefit of first-line nivolumab plus ipilimumab over sunitinib across all intermediate-risk and poor-risk groups, regardless of the number of IMDC risk factors. PATIENT This report from the CheckMate 214 study describes a consistent efficacy benefit with first-line nivolumab plus ipilimumab over first-line sunitinib in all groups of patients with intermediate-risk or poor-risk advanced renal cell carcinoma, regardless of the number of risk factors they had before starting treatment. We conclude that there is a benefit of first-line treatment with nivolumab plus ipilimumab for all intermediate-risk patients, including those with one or two risk factors, and for all poor-risk patients, independent of the number of risk factors.

Conflicts of interest (COIs) can potentially introduce a risk of bias into the assessment of evidence and the formulation of recommendations for guidelines. It is essential that a systematic process for the disclosure and management of COIs is adopted to minimise potential bias in the guideline development process.

Randomized Controlled Trial Comparative Study
Correlation of Prostate-specific Antigen Kinetics with Overall Survival and Radiological Progression-free Survival in Metastatic Castration-sensitive Prostate Cancer Treated with Abiraterone Acetate plus Prednisone or Placebos Added to Androgen Deprivation Therapy: Post Hoc Analysis of Phase 3 LATITUDE Study.
LATITUDE, a randomized, double-blind trial, compared abiraterone acetate and prednisone (AAP) + androgen deprivation therapy (ADT) versus placebo (PBO) + ADT in high-risk metastatic castration-sensitive prostate cancer (mCSPC). ⋯ We found that low prostate-specific antigen levels (≤0.1 ng/ml) after 6 mo may indicate a good long-term response to treatment. Our results need confirmation.
