NCT06184321

Brief Summary

This study investigates whether alteplase can help to improve pleural fluid drainage and dyspnea (breathlessness) in patients with non-draining malignant pleural effusion. Alteplase helps dissolve blood clots and is used to treat heart attacks, strokes, and clots in the lungs. Alteplase may help to control symptoms of breathlessness.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events

    through study completion; an average of 1 year

Study Arms (2)

Arm I (alteplase)

EXPERIMENTAL

Patients receive alteplase instilled into the IPC which is capped for 1-2 hours before the catheter is drained.

Biological: Alteplase

Arm II (placebo)

PLACEBO COMPARATOR

Patients receive placebo instilled into the IPC which is capped for 1-2 hours before the catheter is drained. Beginning 1 week later, patients may receive alteplase as in arm I.

Drug: Placebo Administration

Interventions

Instilled into IPC

Eligibility Criteria

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

You may qualify if:

  • Referral to pulmonary services for inability to drain fully via IPC
  • Presence of a symptomatic septated pleural effusion
  • A pleural effusion of significant moderate to large volume based on:
  • Chest radiograph: effusion filling \>= 1/3 of the hemithorax, or
  • Computed tomography (CT)-scan: AP depth of the effusion \>= 1/3 of the AP dimension on the axial image superior to the hemidiaphragm, including atelectatic lung surrounded by effusion, or
  • Ultrasound: effusion spanning at least three intercostal spaces, with a \>= 3 cm in at least one intercostal space, while the patient sits upright
  • Age \> 18
  • Borg score \>= 3
  • Absence of a blocked IPC as demonstrated by a flush with 20 cc of saline x1 without resistance
  • Presence of septated effusion based on ultrasound (US) and chest CT

You may not qualify if:

  • Inability to provide informed consent
  • Study subject has any disease or condition that interferes with safe completion of the study including:
  • Uncorrectable coagulopathy based on criteria followed by cardiopulmonary center for procedures.
  • Active bleeding
  • Known allergic reaction to thrombolytics
  • Pleural effusion is smaller than expected on bedside pre-procedure ultrasound
  • No septations and/or no loculations on bedside pre-procedure ultrasound
  • Patient is asymptomatic
  • Blocked IPC as determined by saline flush
