Study summary

The aim of this study is to evaluate the efficacy, the safety and the main predictors of success of bronchoscopic Argon Plasma Coagulation in patients with hemoptysis caused by endobronchial malignancies.

Read the detailed description

Hemoptysis is a challenging symptom which may be frequently related to endobronchial malignancies. Patients with central neoplasms and hemoptysis show a lower median survival than patients with no bleeding and endobronchial neoplasms and/or patients with hemoptysis and peripheral malignant lesions.

Hemoptysis control without recurrence at 48 hours after bronchoscopic interventions may improve survival in patients with mild bleeding and endobronchial malignancies.

Argon Plasma Coagulation is considered one of the most effective techniques for endobronchial management of hemoptysis in this subset of patients. Nevertheless, few data are available in literature on its efficacy and safety, and the main predictors of success are still unclear.

In this prospective, observational study, investigators aim to evaluate the efficacy (i.e. immediate bleeding cessation without recurrence during the following 48 hours) of endoscopic Argon Plasma Coagulation in patients with hemoptysis caused by endobronchial neoplasms.

Investigators will also evaluate the safety of the procedure, the main variables associated to a successful intervention, the presence of hemoptysis relapses and patients overall survival to 3,5 months after the bronchoscopic intervention.

Study population

Patients with hemoptysis caused by endobronchial malignancies who need an endoscopic intervention (i.e Argon Plasma Coagulation) to stop the bleeding

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult patients with hemoptysis caused by endobronchial (i.e. identifiable with flexible bronchoscopy) , without coagulopathy or other medically correctable causes of bleeding, who need endoscopic intervention with Argon Plasma Coagulation to stop bleeding
  • Adult patients who are able to tolerate bronchoscopy
  • Adult patients who are able to sign the written for the study participation

Exclusion criteria

Exclusion Criteria:

  • Patients with hemoptysis caused by endobronchial with coagulopathy or other medically correctable causes of bleeding.
  • Patients who are not able to tolerate bronchoscopy
  • Patients with hemoptysis without identifiable endobronchial malignancies during flexible bronchoscopy
  • Patients with Pace-Maker and/or Automated Implantable Cardioverter- Defibrillator(AICD)
  • Patients who refuse/are not able to sign the for the study participation
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Hemoptysis patients

    Hemoptysis patients caused by endobronchial malignancies

    Other: Argon Plasma Coagulation

Interventions

  • OtherArgon Plasma Coagulation

    Patients will be treated with Argon Plasma Coagulation. Argon plasma coagulation (APC) is a form of non contact electrocoagulation. APC utilizes electrically conductive argon plasma as a medium to deliver high-frequency current via a flexible probe. The argon plasma flow transfers electricity between the probe and the target tissue. Tracheobronchial access is obtained by passing the probe through the working channel of the bronchoscope. On arrival to the tissue, the application of energy causes uniform zones of desiccation, coagulation and devitalization in the areas receiving treatment, thus inducing hemostasis.

    Time frame: 48 hours

Secondary outcomes

  1. Incidence of adverse events

    Incidence of adverse events following bronchoscopic Argon Plasma Coagulation in the treatment of patients with hemoptysis and endobronchial malignancies

    Time frame: 48 hours

  2. Incidence of hemoptysis recurrences

    Incidence of hemoptysis recurrences (number of relapses)

    Time frame: 3,5 months

  3. Number of patients with hemoptysis and endobronchial malignancies who are still alive at the end of the follow-up

    Number of patients with hemoptysis and endobronchial malignancies who are still alive after 3,5 months after the endoscopic intervention

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 Aug 1, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
