Conditions

Outcome Measures

Primary Outcomes (1)

  • Incidence of referral to surgery

    Treatment failure, as evidenced by continued or worsening pleural sepsis and failure to adequately drain pleural effusion, resulting in referral to surgery

    Post treatment (Day 4/Hospital discharge or at time of treatment failure)

Secondary Outcomes (1)

  • Relative change in pleural opacity

    Post treatment (Day 4 or at time of treatment failure)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female ≥ 18 years of age who provide written informed consent
  • Clinical presentation compatible with complicated parapneumonic pleural effusion (CPE), empyema or other type of pleural infection
  • Has pleural fluid requiring drainage as determined by chest ultrasonography or by chest CT, and which is either:
  • a) purulent; b) gram stain positive; c) culture positive; d) pH \< 7.2; or e) glucose \< 60 mg/dL (3.3 mmol/L)
  • Failure to adequately drain pleural fluid ≥ 3 hours post insertion of patent chest tube within the pleural space, as evidenced by one or more of the following criteria:
  • \> 2 cm depth of fluid by ultrasound or CT
  • \< 80% drainage from chest radiograph obtained prior to chest tube insertion.

You may not qualify if:

  • Current pleural infection already treated with intrapleural fibrinolytic therapy
  • Evidence of ipsilateral fibrothorax (e.g. CT scan with \> 0.5 cm visceral pleural thickening)
  • History of multiple thoracenteses or thoracic surgical procedures within 3 months of screening
  • Previous pneumonectomy on the side of the pleural effusion
  • Current bilateral pleural infections
  • Known non-expandable lung prior to this pleural infection
  • Known or high clinical suspicion of a malignant pleural effusion
  • Existing indwelling or tunneled pleural catheter
  • Current infected hepatic hydrothorax or evidence of another abdominal process (e.g. pancreatic cyst or renal cyst) communicating with the pleural space
  • Active bleeding, or any condition in which bleeding is either a significant risk or would be difficult to manage
  • Fully anticoagulated patients on heparin, warfarin or novel oral anti-coagulants who are not able to temporarily discontinue anti-coagulants while receiving study medication and for 2 days after last dose of study medication Note: patients receiving low-molecular weight heparin for immobilization or anti-platelet agents are not excluded.
  • Presence of severe metabolic derangements that would interfere with study assessments
  • Systolic blood pressure \>185 mmHg or diastolic blood pressure \> 110 mmHg at screening
  • Hemodynamically unstable and/or requires use of intravenous vasopressor therapy
  • Expected survival \< 3 months from a pathology other than the qualifying infected, non-draining pleural effusion (e.g. metastatic lung carcinoma)
