What You Need to Know Before You Apply

What is the purpose of this trial?

This trial investigates the safety and feasibility of using nebulized revefenacin, a medication inhaled through a nebulizer, to assist people with COPD who experience severe breathing problems and require mechanical ventilation. The study compares revefenacin with another nebulized treatment, ipratropium bromide, to determine which is more effective for these patients. Individuals with a long history of COPD, over 10 years of smoking, and current use of a ventilator may be suitable candidates for this trial. As a Phase 2 trial, the research focuses on evaluating the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

If you are taking short- or long-acting muscarinic antagonists, you will need to stop them for a washout period (time without taking certain medications) of 6 hours for short-acting and 24 hours for long-acting before starting the study drug. Other medications are not specified, so it's best to discuss with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that revefenacin is generally safe for people with COPD and is well-tolerated when used daily. In trials, most participants did not experience serious side effects. Some reported mild issues like a cough or headache, but these were uncommon. The FDA has already approved revefenacin for COPD, indicating thorough safety testing.

Ipratropium has long been used to help with breathing problems in COPD. It is usually well-tolerated, though some individuals might experience a dry mouth or dizziness. These side effects are typically mild and manageable.

Overall, past research and approvals have demonstrated that both treatments are safe for people with COPD. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for COPD?

Unlike the standard treatments for COPD, such as inhaled bronchodilators like albuterol and ipratropium bromide, Revefenacin offers a unique approach. It is a long-acting muscarinic antagonist (LAMA) that is delivered once daily via nebulizer, which can be more convenient for patients who struggle with handheld inhalers. Researchers are excited about Revefenacin because its once-daily dosing could improve adherence and provide consistent symptom control throughout the day. Additionally, its targeted action might reduce the risk of systemic side effects commonly associated with other COPD medications.

What evidence suggests that this trial's treatments could be effective for COPD-related respiratory insufficiency?

Studies have shown that revefenacin, which participants in this trial may receive, improves lung function in people with COPD. Research indicates it can increase lung capacity by at least 100 mL, with effects lasting over four hours. Importantly, revefenacin provides consistent symptom control with just one daily dose, enhancing breathing throughout the day. These findings suggest it may help manage breathing problems in people with COPD. Another treatment option in this trial is ipratropium, delivered via nebulizer every six hours. ^{4 6 7 8 9}

Trial Overview

The trial is testing revefenacin inhalation solution against ipratropium bromide in patients with COPD who are receiving invasive mechanical ventilation. The goal is to see which treatment is safer and works better under these conditions.

How Is the Trial Designed?

Group I: Revefenacin Experimental Treatment 1 Intervention

Revefenacin will be delivered once daily via nebulizer. In order to allow for full blinding and steady Q6 hours regimen in control arm, at hours 6, 12 and 18 after the Revefenacin dose, nebulized normal saline will be delivered.

Group II: Ipratropium Active Control 1 Intervention

Nebulized ipratropium will be delivered via nebulizer Q6 hours.

Ipratropium Bromide is already approved in European Union, United States, Canada, Japan for the following indications:

Approved in European Union as Atrovent for:

• Chronic obstructive pulmonary disease (COPD)
• Bronchospasm

Approved in United States as Atrovent for:

• Chronic obstructive pulmonary disease (COPD)
• Bronchospasm

Approved in Canada as Combivent for:

• Chronic obstructive pulmonary disease (COPD)
• Bronchospasm

Approved in Japan as Ipravent for:

Published Research Related to This Trial

In a study involving 780 patients with COPD, both doses of inhaled formoterol (12 or 24 microg) were found to be significantly more effective than ipratropium bromide in improving lung function, as measured by forced expiratory volume in 1 second (FEV1) over 12 weeks.

Formoterol also led to significant improvements in patient symptoms and quality of life compared to placebo, while ipratropium did not show meaningful clinical benefits despite improving airflow obstruction.

In a study of 20 patients with mild to moderate persistent asthma, nebulized Ipraterol demonstrated a rapid bronchodilation effect similar to Berodual, significantly increasing FEV1 within 5 minutes and maintaining this effect for up to 6 hours.

Ipraterol provided comparable improvements in pulmonary function to Berodual without significant systemic absorption leading to hypokalemia, indicating it is a safe and effective alternative for asthma treatment.

Revefenacin (YUPELRI™) is the first and only once-daily nebulized bronchodilator approved in the USA for treating chronic obstructive pulmonary disease (COPD), highlighting its unique position in COPD management.

The approval by the US Food and Drug Administration in November 2018 was based on positive results from three phase III trials, demonstrating its efficacy for maintenance treatment in COPD patients.

The ipratropium bromide/albuterol Respimat inhaler (CVT-R) demonstrated significantly higher patient satisfaction compared to both the metered-dose inhaler (CVT-MDI) and the dual monotherapy inhalers (I + A) over a 48-week study involving 470 COPD patients.

While the time to first COPD exacerbation was slightly longer for CVT-R, it did not reach statistical significance, and the rates of adverse events were similar across all treatment groups, indicating that CVT-R is a safe and effective alternative with potential clinical benefits.

In a 1-year study involving 456 patients with moderate-to-severe COPD, the new ipratropium bromide metered-dose inhaler (IB HFA) demonstrated similar efficacy and safety compared to the traditional chlorofluorocarbon (IB CFC) inhaler, with no significant differences in adverse events.

Both inhalers achieved therapeutic bronchodilatory responses in a high percentage of patients (76-81% for IB HFA and 72-84% for IB CFC), indicating that IB HFA is a viable alternative for long-term COPD management.

In a study of 110 patients with COPD and respiratory failure, the combination of ipratropium bromide and non-invasive ventilation significantly improved blood gas indexes and pulmonary function compared to non-invasive ventilation alone.

Patients receiving the combination treatment also experienced better overall efficacy, improved quality of life, and fewer adverse reactions, highlighting the safety and effectiveness of this approach.

In a post hoc analysis of two 12-week phase 3 trials involving 812 patients with moderate to very severe COPD, once-daily nebulized revefenacin significantly improved patient-reported outcomes, including the St. George's Respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT), compared to placebo.

The improvements in health status were more pronounced in women, with a greater proportion achieving clinically meaningful responses in SGRQ scores, indicating that revefenacin is an effective maintenance treatment for COPD, particularly in female patients.

In a 12-week study involving 1209 patients with moderate to severe COPD, the ipratropium bromide/albuterol Respimat inhaler showed comparable efficacy to the CFC-metered dose inhaler (MDI) for improving lung function, measured by forced expiratory volume in 1 second (FEV1).

The Respimat inhaler demonstrated superior efficacy compared to the mono-component ipratropium Respimat inhaler, while all treatments were well tolerated, indicating that the combination inhaler is both effective and safe for COPD management.

The combination therapy of albuterol and ipratropium bromide improves airflow in COPD patients more effectively than either medication alone, simplifying treatment and enhancing patient compliance.

However, newer and more potent medications have emerged that offer greater benefits than the albuterol-ipratropium combination, indicating a shift in preferred treatment options for stable COPD.
