SEAL-IT Trial Summary

This trial is testing a new heart medication in patients with a left ventricular assist device (LVAD). The goal is to see if the new drug is better tolerated and more effective than the current standard of care.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.

Primary outcome measures

Incidence of drug discontinuation from drug-related adverse events due to sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 3 months

Time-averaged proportional change in NT-proBNP concentration (pg/mL) with sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 3 months

Secondary outcome measures

Absolute change in cardiac index (L/min/m2) with sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 6 weeks and/or 3, 6 and/or 12 months

Absolute change in indexed left atrial volume (mL/m2) on echocardiogram with sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 6 weeks and/or 3, 6 and/or 12 months

Absolute change in indexed right atrial volume (mL/m2) on echocardiogram with sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 6 weeks and/or 3, 6 and/or 12 months

Experimental Treatment

Active Control

Group I: Sacubitril-valsartan study armExperimental Treatment1 Intervention

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.

Group II: Usual care (standard-of-care) armActive Control1 Intervention

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.
