About this study

Official title: Safety and Efficacy of Angiotensin Receptor-neprilysin Inhibitor After Left Ventricular Assist Device ImplanT (SEAL-IT) Study

The purpose of the study is to evaluate how well tolerated and effective an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) is in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to usual care oral vasodilator therapy.

Read the detailed description

The aim of this pilot study is to prospectively determine the short-term (at 3 months) and long-term (at 6 and 12 months) safety and efficacy of an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to standard-of-care (usual care) oral vasodilator therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sacubitril-ValsartanDrug

    Also called Entresto

    Sacubitril-valsartan at low or equivalent dose to be initiated or added to patients randomized to this arm, and titrated up every 2-4 weeks, per standard practice guidelines and label recommendations per physician's discretion.

  • Usual care (standard-of-care) armDrug

    Also called Oral Vasodilator

    Other oral vasodilator therapy to be continued or initiated to patients randomized to this arm, and titrated up every 2-4 weeks, per standard practice guidelines and label recommendations per physician's discretion.

Study groups in NCT04191681
Study groupRoleWhat they receive
Sacubitril-valsartan study armExperimental1. Start medication-naïve patients on low-dose sacubitril-valsartan (24/26 mg PO BID) without a washout period per guideline and label recommendations. 2. 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). 3. 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. 4. Sacubitril-valsartan can be up-titrated every 2-4 weeks per standard practice guidelines per physician's discretion as above.
Receives: Drug: Sacubitril-Valsartan
Usual care (standard-of-care) armActive comparator1. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sacubitril-Valsartan in people with Stage D Heart Failure, run by The Cleveland Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 7 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jerry D Estep, MD (216-444-7646, estepj@ccf.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of drug discontinuation from drug-related adverse events due to sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 3 months (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04191681, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jun 2021.
