Combination Tissue Plasminogen Activator (Tpa) and Dornase Alfa (Dnase) Administration Through Intrapleural Catheters for the Treatment of Loculated or Non-Draining Malignant Pleural Effusions

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and safety of intrapleural dornase alfa and tPA administered to patients with clinical failure of small-bore chest tube with persistent pleural effusions or malignancy-related loculated effusion to improve pleural drainage.

Conditions
-----------------
Loculated or Non-draining Malignant Pleural Effusions

Intervention / Treatment
-----------------
* Drug: Combination TISSUE PLASMINOGEN ACTIVATOR (TPA) AND DORNASE ALFA (DNASE)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Clinical failure of small-bore chest tube with persistent pleural effusion 18 years of age or older Eastern Cooperative Oncology Group (ECOG) performance status score 0-2. Life expectancy ≥ 6 weeks Absolute neutrophil count > 1500 mm3, platelet count ≥ 100×109 L, hemoglobin ≥ 8.0 g/dL Serum creatinine ≤2.0 times the upper limit of the normal range, total bilirubin ≤ 2.5 mg/dL, AST/ALT ≤ 5 times the upper limit of normal range At least 2 days from administration of chemotherapy At least 7 days from prior major surgery Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must be willing to use an acceptable contraceptive method (abstinence, oral contraceptive or double barrier method) for the duration of the study and for 30 days following the last dose of study drug, and must have a negative urine or serum pregnancy test within 2 weeks prior to beginning treatment on this trial. Patient judged to be 'medically stable' by primary investigator. Exclusion Criteria: Prior treatment with intrapleural fibrinolytic agents Presence of any intracranial mass Traumatic hemorrhagic pleural effusion Major hemorrhage, coincidental stroke, or major trauma High-risk for systemic bleeding Allergy or intolerance to dornase alfa Active clinically serious infection > CTCAE (version 4.03) Grade 2. Serious non-healing wound, ulcer, or bone fracture. Major surgery, open biopsy or significant traumatic injury within seven (7) days of first study drug--including neurosurgery. Inability to complete informed consent process and adhere to the protocol treatment plan and follow-up requirements. Concurrent severe illness such as active infection, or psychiatric illness/social situations that would limit safety and compliance with study requirements. Patients who are pregnant or lactating (females of childbearing potential must have a negative pregnancy test prior to participation in this study) Expected survival less than six weeks
