Lisinopril

Clinical trials investigating Lisinopril are studying its use in heart failure and heart failure in remission. These studies look at how treatment changes may affect outcomes such as survival, readmission, quality of life, and heart structure. The trials include adults in a phase 3 setting.

Trial overview

Two authorised interventional studies are investigating Lisinopril as part of heart failure research.[1][2] Both studies are in Phase 3, which means they are later-stage trials with patient outcomes as the main focus.[1][2]

The first study looks at how guideline-directed medical therapy, or GDMT (the recommended treatment plan for heart failure), is used and whether there are sex-related differences in care.[1] The second study looks at whether partial withdrawal of heart failure therapy is safe and feasible in patients whose heart failure is in remission.[2]

Heart failure sex-gap study

The study titled “Pharmacological optimization in prevention in Heart Failure: A Sex-gap?” is a Phase 3 interventional trial with 368 planned participants and an authorised status.[1] It focuses on people with heart failure and uses registry data to describe the current pattern of GDMT use across the country.[1]

This study also examines inequality related to sex, meaning it wants to see whether women and men receive similar heart failure treatment in real life.[1] The brief summary says the prospective part is a pragmatic multicentre trial, which means it is designed to fit routine care in several hospitals and to study results in a practical setting.[1]

The treatment list in this trial includes many heart failure medicines, and Lisinopril is one of them.[1] Other listed medicines include several other blood pressure and heart failure drugs, but the trial focus is not the drug alone; it is the wider treatment strategy and outcomes in heart failure care.[1]

Heart failure remission study

The second study is titled “A trial investigating partial withdrawal of heart failure therapy in patients with heart failure in remission.”[2] It is also authorised, Phase 3, and planned for 100 participants.[2]

This trial studies whether reducing heart failure therapy, instead of continuing it, is safe and workable in patients whose heart failure is in remission.[2] In this study, Lisinopril appears in the treatment list together with other heart failure medicines such as Jardiance, bisoprolol, and spironolactone.[2]

The main idea is not to test Lisinopril alone, but to understand what happens when heart failure treatment is partly withdrawn compared with continuing treatment.[2]

Endpoints and measures

An endpoint is the main result a trial measures to see whether the strategy works.[1][2] In the first study, the retrospective part measures the current status of GDMT prescription and sex-related inequality using national registry data and a database called Mecki.[1]

The prospective part of the first study measures all-cause mortality within 1 year, heart failure readmission, and worsening heart failure.[1] It also looks at quality of life, adherence to drugs, meaning whether patients stay on treatment as planned, and side effects.[1]

In the second study, the primary outcomes are left ventricular remodeling, NT-proBNP increase to more than 500 pg/mL, and all-cause mortality.[2] Left ventricular remodeling means changes in the heart’s main pumping chamber, and the study measures this in a core echocardiography laboratory.[2]

The remodeling endpoint is defined as an increase in left ventricular end-systolic volume index of more than 20% from baseline, which is the first measurement taken before treatment changes.[2] NT-proBNP is a blood marker that can rise when heart failure becomes worse.[2]

Who the trials are for

These studies are for adults with heart failure or heart failure in remission.[1][2] The first study specifically aims to understand treatment gaps in women with heart failure during follow-up, so women are an important target group in that trial.[1]

The second study includes patients whose heart failure is in remission, meaning their condition is currently controlled enough for the research team to study partial withdrawal of therapy.[2] Both trials are meant to reflect real clinical care and to answer practical questions about treatment strategy rather than to test Lisinopril as a single stand-alone treatment.[1][2]

What Phase 3 means

Phase 3 trials usually study a treatment in larger groups of people to learn how well it works and how safe it is in the target population.[1][2] In these two studies, Phase 3 supports the idea that the researchers are looking for meaningful patient outcomes such as survival, hospital use, heart function, and quality of life.[1][2]

Because both studies are interventional, the researchers are not only observing patients; they are also testing different treatment approaches and comparing outcomes over time.[1][2]

Glossary

  • Heart failure: A condition where the heart does not pump blood as well as it should.
  • Heart failure in remission: A state where heart failure symptoms are improved or controlled, but the condition is still being watched closely.
  • Phase 3: A later stage of research that studies a treatment in larger groups of people to learn more about how well it works and how safe it is.
  • Interventional study: A trial where researchers assign a treatment or change in care and then measure the results.
  • Randomisation: A process where participants are placed into study groups by chance.
  • Up-titration: A planned increase in treatment dose over time.
  • Down-titration: A planned decrease in treatment dose over time.
  • Morbidity: Illness or health problems caused by a condition.
  • Mortality: Death.
  • Echocardiography: An ultrasound test of the heart that shows how the heart looks and moves.
  • Left ventricular end-systolic volume index: A measure of how much blood remains in the left side of the heart after it contracts, adjusted for body size.
  • NT-proBNP: A blood marker that can rise when heart failure gets worse.
