Nivolumab plus Ipilimumab in Advanced Melanomadoi: 10.1056/NEJMc2501311pmid: 40138567
To the Editor: In the final, 10-year outcomes of the CheckMate 067 trial reported by Wolchok et al. (Jan. 2 issue),1 the combination of nivolumab and ipilimumab resulted in an unprecedented increase in overall and melanoma-specific survival, as compared with ipilimumab alone. We should be wary of the fact that this combination was not designed to be compared with nivolumab alone, and the difference in survival between the two trial groups was not significant. This finding is noteworthy, given that nivolumab alone had an incidence of adverse events of only 25% (as compared with 63% in the combination group). Among . . .
Asundexian versus Apixaban in Patients with Atrial Fibrillationdoi: 10.1056/NEJMc2501201pmid: 40138570
To the Editor: Inhibition of factor XI or activated factor XI (XIa) should provide protection against stroke with a low risk of bleeding, given that the incidence of bleeding or adverse cardiovascular events is low among persons with intrinsic factor XI deficiency. In the OCEANIC-AF trial reported by Piccini et al. (Jan. 2 issue),1 patients who received asundexian at a once-daily dose of 50 mg had a lower risk of bleeding than those who received apixaban; however, asundexian was associated with a higher risk of stroke or systemic thromboembolism than apixaban (hazard ratio, 3.79; 95% confidence interval, 2.46 to 5.83), . . .
