Sacubitril/Valsartan Shows No Superiority Over Enalapril in Pediatric HF, Study Finds

• 375 children (mean age: 8.1±5.6 years, 52% female) were randomized to receive either sacubitril/valsartan (n=187) or enalapril (n=188) in the trial.

• No statistically significant difference was established between the groups in the 52-week endpoint defined as the global rank, with a probability value of 0.52 (95% CI: 0.47-0.58) and odds at the Mann-Whitney test of 0.91 (95% CI: 0.72-1.14), evidencing no statistical superiority of sacubitril/valsartan over enalapril.

• Both treatment groups showed marked reductions in NYHA/Ross classification, PGIS, Patient Global Impression of Change, and NT-proBNP levels at 52 weeks with no between-group differences.

• Safety of both agents seems to be equivalent with adverse event rates reached by 88.8% in the sacubitril/valsartan and 87.8% in the enalapril; hence, sacubitril/valsartan seems very well tolerated in children.

The researchers concluded that both drugs are associated with clinically significant improvements over a period of 52 weeks, with similarities between their safety profiles; thus, safer alternatives for pediatric patients exist. Further research is needed to confirm potential benefits in specific pediatric populations with HF or with other drugs in addition to sacubitril/valsartan.
