Trial summary

Patients with cancer may experience problems with their breathing due to a fluid accumulation around their lungs called malignant pleural effusion (MPE). This fluid can be drained but draining may not stop the fluid from accumulating again. Read more about this study

About this study

Official title: Outpatient Pleurodesis Using Sclerosants(OPUS):Comparing Doxycycline Pleurodesis to Continued Drainage With the Pleurx Catheter System in the Treatment of Malignant Pleural Effusions in the Outpatient Setting

Patients with cancer may experience problems with their breathing due to a fluid accumulation around their lungs called malignant pleural effusion (MPE). This fluid can be drained but draining may not stop the fluid from accumulating again. MPE can cause shortness of breath during activity and at rest leaving patients feeling as though they cannot catch their breath enough to be comfortable. Other symptoms can include pain, cough and weight loss.

One way to stop the fluid from accumulating is to create scar tissue between the lung and chest wall so there is no more room for fluid accumulation. This procedure is called pleurodesis. Pleurodesis is the standard of care at most centres across Canada. This procedure is done by injecting a drug into the space between the lung and chest wall through a catheter, Doxycycline is one of the drugs currently used for this purpose. Traditionally, patients are admitted for pleurodesis, mostly because the size of the catheter used to inject the medication is very large but also because of the potential complications that can happen with these larger chest tubes.

At our centre, most patients with MPE are managed at home with a smaller sized catheter known as a Pleurx catheter. The Pleurx catheter allows patients to remain at home for treatment and trained staff come into the home to both drain the MPE and monitor the patient. Sometimes, patients experience pleurodesis through use of the Pleurx catheter alone.

Pleurodesis with doxycycline can happen faster than with the Pleurx catheter alone. It has been our experience with a limited number of patients that it is safe to perform pleurodesis using the Pleurx catheter for doxycycline injection in an outpatient setting.

Read the detailed description

Malignant pleural effusions (MPE) occur in 25 - 50% of malignancies, represent advanced disease and carry with it significant morbidity. It is estimated that 75% of malignant effusions are symptomatic at the time of presentation, with dyspnea being the most common complaint. Cough, weight loss and chest pain may also be presenting symptoms. The diagnosis of MPE often carries with it a poor prognosis with an average survival of 3-9 months. Thus, management of MPE is generally palliative, aimed at alleviating the associated symptoms, while incurring minimal discomfort and disruption of patients activities of daily living. Limiting the number of days spent hospitalized ia also a consideration. Currently, the most common treatment for MPE involves tube thoracostomy and pleurodesis using a sclerosing agent. Use of Doxycycline as a sclerosing agent has been shown to be both safe and efficacious with only minor complications. Traditionally, pleurodesis with Doxycycline has been performed in the inpatient setting.

The Pleurx catheter (Cardinal Biomedical) is the only small bore catheter commercially available that has been specifically designed for long term indwelling drainage of MPE. In order to reduce the chance of dislodgement and minimize infection rates, it is tunnelled under the skin for approximately 5 cm before entering the pleural space. These indwelling catheters can provide excellent symptom control and have also been associated with spontaneous pleurodesis rates comparable to many chemical pleurodesis rates.

Pleurx has been compared to inpatient doxycycline pleurodesis via chest tube with no difference in survival, safety or efficacy noted. However, hospital stay was significantly shorter in the Pleurx group, 1 day versus 6.5 days.

The aim of this study is to determine the effectiveness of outpatient pleurodesis, using doxycycline administered via Pleurx catheter. This will be a randomized clinical trial comparing the time to pleurodesis in patients with malignant pleural effusion receiving doxycycline + Pleurx catheter versus Pleurx catheter alone.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to pleurodesis

    measured in days after Pleurx catheter insertion up to 90 days

    Measured: up to 90 days post PleurX insertion

Secondary outcomes (3)
  1. Pleurodesis rates at 90 days post Pleurx insertion

    defined by the BTS guidelines, where complete pleurodesis is defined as lack of fluid re-accumulation, allowing for removal of the pleural catheter. Failed pleurodesis is defined as re-accumulation of fluid and symptoms requiring repeated pleural procedures

    Measured: 90 days post Pleurx insertion

  2. Number of participants with adverse events

    Most common complications include: pleural infection / cellulitis, pain, catheter obstruction and symptomatic loculated effusion. Other adverse events will also be collected.

    Measured: 90 days post Pleurx insertion

  3. Effects on pulmonary function

    Pulmonary Function testing will be performed prior to and post PleurX catheter insertion and prior to each follow up visit

    Measured: 90 days post Pleurx insertion

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Doxycycline and normal saline in people with Malignant Pleural Effusion, run by Ottawa Hospital Research Institute at 2 sites in Canada.

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 25 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Rosalie Labelle, MSc (613-737-8899 ext. 75256, rolabelle@toh.on.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to pleurodesis (time frame: up to 90 days post PleurX insertion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Sep 2020.
