Trial Outcomes & Findings for Efficacy and Safety of Activase (Ateplase) vs Placebo in Complicated Pleural Effusions (CPE)/Empyemas (NCT NCT00468104)

NCT ID: NCT00468104

Last Updated: 2012-04-30

Results Overview

CT scans of the chest and Chest X rays (CXR) were used to determine resolution of Pleural effusions/empyema/ pneumonia after 3 days of Alteplase/ Placebo therapy. If no response was noted with the first intervention patients were offered surgery --Decortiation/ Video Assisted Thoracic Surgery (VATS) or to receive the second intervention. Patients that failed the second intervention were offered surgery.

Recruitment status

Participant Flow

Patients with loculated pleural effusions that failed to respond to chest tube placement and standard medical treatment and were considered for surgery were given the option to enter into a double blind cross over trial

108 patients were evaluated but only 100 entered the trial. 2 patients refused, 2 patients admitting physicians opted out of the trial, 3 patients chest tube removed inadvertently, 1 patient for coagulopathy

Measure
Alteplase Then Placebo
25 mg of Alteplase in 100 cc of normal saline was instilled intrapleurally daily for three days. Chest CT scans were performed on the fourth day . If less than a 50% reduction in the pleural effusion was determined, the patient was given the option to go to surgery or to the second intervention of the trial (with Placebo)
Placebo Then Alteplase
Placebo in 100 cc of normal saline was instilled intrapleurally daily for three days. Chest CT scans were performed on the fourth day . If less than a 50% reduction in the pleural effusion was determined, the patient was given the option to go to surgery or to the second intervention of the trial (with Alteplase)

PRIMARY outcome

Timeframe: patients were followed six weeks per protocol. Most patients treated with Alteplase were also followed for up to six months

Population: intention to treat

If no response was noted with the first intervention patients were offered surgery --Decortiation/ Video Assisted Thoracic Surgery (VATS) or to receive the second intervention.
