Study summary

The aim of this study was to assess the efficacy of the modified regimen short duration intrapleural 16mg alteplase (Actilyse, Boehringer Ingelheim) with 5mg DNase (Pulmozyme Hoffmann-La Roche Ltd) in patients with pleural infection.

Read the detailed description

The regimen 10 mg alteplase and 5 mg DNase twice daily that was used in MIST-2 trial is still an empiric choice. The rationale of using 3 doses of 16 mg alteplase dose (with supplementary 5 mg DNase) in our study was governed by the formulation of alteplase in our country (50 mg per ampoule); hence, it is best used within 24 hours following reconstitution as its biochemical stability up to 24 hours as assessed by in vitro clot lysis assays.

Inclusion criteria

  • adult patient with age more than 17 year old
  • evidence of complex parapneumonic effusion or empyema; with poor pleural fluid drainage of ≤150 mL after 24 hours of insertion of chest drain
  • clinical evidence of infection such as fever and or elevated C-reactive protein (CRP) or white-cell count
  • complex pleural effusion proven by ultrasound
  • pleural fluid analysis that fulfilled at least one of the characteristics: frank pus, exudative nature (according to light's criteria), gram stain or culture positive, lactate dehydrogenase (LDH) > 1000 U/L, pH \< 7.2 and/or glucose level \< 3.3mmol/L

Exclusion criteria

Exclusion Criteria:

  • known allergy to pulmozyme or alteplase
  • acute stroke, active bleeding diathesis
  • major surgery in past 5 days
  • previous pneumonectomy on the infected side
  • bronchopleural fistula
  • pregnancy
  • coagulopathy ( > 2, APTT >100, count \< 50,000 cells)
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.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

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 Jun 7, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
