Study summary

Post-market clinical study (registry study) to collect post-market safety and clinical utility data in European patients with chronic bronchitis treated with RheOx.

Read the detailed description

RheOx is a device-based, energy delivery system that delivers high frequency short duration energy to the airway epithelium and sub-mucosal tissue layers. The energy is delivered via a proprietary catheter through the bronchoscope.

Two sessions of treatment will be delivered one month apart. The right lung is treated at the first treatment session and the left lung is treated at the second treatment session (approximately one month after the right side is treated). Treatment will be delivered by a respiratory physician (interventional pulmonologist) in a tertiary teaching hospital during a bronchoscopic procedure. The bronchoscopy will be delivered during general anaesthesia. It is anticipated that the bronchoscopic procedure will last less than 60 minutes in total. Treatment will be deemed to have been delivered following the successful treatment during the two bronchoscopies.

Subjects will be required to submit to several tests and questionnaires during the study including respiratory function tests.

What researchers measure

Primary outcomes

  1. Safety: Incidence of SAEs

    Incidence of serious adverse events associated with RheOx treatment through 24 months

    Time frame: Through end of study (24 months post bilateral treatment)

  2. Quality of Life: CAT

    COPD Assessment Test (CAT) questionnaire

    Time frame: Through end of study (24 months post bilateral treatment)

  3. Quality of Life: SGRQ

    St. George Respiratory Questionnaire

    Time frame: Through end of study (24 months post-bilateral treatment)

Secondary outcomes

    Time frame: Through end of study (24 months post-bilateral treatment)

  2. Pulmonary Function: FVC

    Forced Vital Capacity

    Time frame: Through end of study (24 months post-bilateral treatment)

  3. COPD Exacerbations

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2020 (actual). Primary completion is estimated for Dec 2024, 59 months after the start.

Of 24 interventional studies with no phase under Bronchitis, Chronic, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 47. This study's planned 59 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 22, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
