简要总结
This randomized placebo-controlled clinical trial will evaluate the effect of sacubitril/valsartan (compared with placebo) on echocardiographic measures of hypervolemia, preservation of residual renal function, and key safety parameters in incident hemodialysis patients.

Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing of investigational drug and for 7 days off of study drug.
研究组 & 干预措施
sacubitril/valsartan
Experimental
Participants will take sacubitril/valsartan, beginning dose of 24/26mg twice daily, with titration to target dose of 97/103 mg twice daily over the first four weeks. Patients will remain on the maximally tolerated dose for the remaining 12 weeks (total on-drug period of 16 weeks) before stopping drug and being followed for a further two weeks (total study time of 18 weeks).
干预措施: Sacubitril-valsartan (Drug)
placebo
Placebo Comparator
Participants will take equivalent placebo, beginning equivalent dose of 24/26mg twice daily, with titration to target equivalent dose of 97/103 mg twice daily over the first four weeks. Patients will remain on the maximally tolerated dose for the remaining 12 weeks (total on-drug period of 16 weeks) before stopping drug/placebo and being followed for a further two weeks (total study time of 18 weeks).
