What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial focuses on inflammatory cardiovascular involvement that occurs after COVID-19 infection. The study aims to evaluate the effectiveness of a combined treatment approach using two medications: prednisolone (a steroid that reduces inflammation) and losartan (a medication that helps protect the heart) compared to placebo in patients who have heart inflammation following COVID-19 infection.

The condition being studied is detected through special heart imaging called Cardiovascular Magnetic Resonance imaging, which can show inflammation in the heart tissue. The treatment involves taking tablets of prednisolone and losartan by mouth for 16 weeks. Some participants will receive the actual medications, while others will receive placebo tablets that look the same but contain no active medication.

The study will measure how well the heart functions before and after treatment using detailed heart imaging. This will help determine if the combination of medications can reduce heart inflammation and improve heart function in people who have developed heart problems after COVID-19 infection. The treatment's safety will also be monitored throughout the study period.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial assessment

    A cardiovascular magnetic resonance (CMR) scan will be performed to confirm heart inflammation related to COVID-19

    The scan will measure your heart function and look for signs of inflammation in the heart tissue

  2. Step 2

    Treatment start

    You will receive either:

    - Active treatment: prednisolone tablets (starting with 10 mg, then 5 mg) and losartan tablets (starting with 12.5 mg, increasing to 25 mg), or

    - Placebo tablets (containing inactive ingredients)

    Neither you nor your doctor will know which treatment you are receiving

  3. Step 3

    Treatment duration

    The treatment will continue for 16 weeks

    You will need to take the medication as prescribed and keep a diary of your medication use

  4. Step 4

    Follow-up assessment

    After 16 weeks, another CMR scan will be performed to measure changes in your heart

    Additional tests will include:

    - Exercise capacity test

    - Heart muscle measurements

    - Assessment of your symptoms

  5. Step 5

    Long-term follow-up

    Your health status will be monitored for up to one year after treatment completion

    The doctors will track any heart-related events or complications during this period

Investigated drugs

Based on the provided trial data, I cannot extract specific medications as there are no medications clearly listed in the source data. While the trial title (MYOFLAME-19) and objective mention "immunosuppressive and antiremodelling therapy," the specific medications are not detailed in the provided information. Without explicit medication names, I cannot provide accurate descriptions of the treatments involved in this clinical trial. The trial appears to be comparing some form of combined therapy against placebo for treating COVID-19-related cardiac inflammation, but the specific medications used are not included in the source data.

What is already known about the treatment

Based on the provided clinical trial data, the trial involves a combined immunosuppressive and antiremodeling therapy, but specific medications are not listed in the source data. Without explicit medication names from the trial data, I cannot create medication descriptions in the requested format. The trial appears to be studying treatment for COVID-19-related cardiovascular inflammation, but the specific therapeutic agents are not disclosed in the provided information. If you could provide the specific medications being tested in this MYOFLAME-19 trial, I would be happy to create descriptions following the requested format.

Investigated diseases

COVID-19 Related Inflammatory Cardiovascular Disease - A condition that develops as a complication of COVID-19 infection, affecting the heart and blood vessels. The disease involves inflammation of the heart muscle and surrounding tissues, which can be detected through cardiovascular magnetic resonance imaging. This condition can affect the heart's ability to pump blood effectively and may cause changes in heart muscle tissue. The inflammation can impact both the left and right ventricles of the heart, potentially leading to changes in heart function. The condition may also affect the blood vessels, including the aorta, and can cause various cardiovascular symptoms.
