Active Comparator
Sacubitril-valsartan study arm
Usual care (standard-of-care) arm
Start medication-naïve patients on low-dose sacubitril-valsartan (24/26 mg PO BID) without a washout period per guideline and label recommendations. Switch patients to equivalent dose sacubitril-valsartan if on prior ACE inhibitor (after a 36 hour washout period) or ARB therapy (after discontinuing one day prior). If therapeutic range MAP (65 to 85 mm Hg), discontinue other oral vasodilator (e.g., hydralazine, isordil) or non-rate limiting dihydropyridine calcium channel blocker (non-DHP CCB, e.g., amlodipine) therapy on the day prior to sacubitril-valsartan initiation. If MAP > 85 mm Hg, low-dose sacubitril-valsartan will be added with or without discontinuation of other oral vasodilator or non-DHP CCB per physician's discretion based on drug tolerability and maintenance of therapeutic range MAP. Sacubitril-valsartan can be up-titrated every 2-4 weeks per standard practice guidelines per physician's discretion as above.
1. Continue current regimen of patients on oral vasodilator therapy (e.g., ACE inhibitor, ARB, hydralazine, isordil), allowing for up-titration of the drug every 2-4 weeks per standard practice guidelines in keeping with physician's discretion as above. 2. Start medication-naïve patients de novo on one of the oral vasodilators as below per guideline and label recommendations, allowing for up-titration of the drug every 2-4 weeks per standard practice guidelines in keeping with physician's discretion as above: i. ACE inhibitor: Enalapril 2.5 mg PO BID or Lisinopril 5 mg PO daily; ii. ARB: Valsartan 20 mg PO BID or Losartan 25 mg PO daily; iii. Other: Hydralazine 10 mg PO TID or Isordil 5 mg PO TID.
