Indwelling Pleural Catheters With or Without Doxycycline in Treating Patients With Malignant Pleural Effusions

About the study

This study is designed to obtain preliminary data comparing indwelling pleural catheters (IPCs) versus IPCs plus doxycycline for pleurodesis as treatments for malignant pleural effusion (MPE). Indwelling pleural catheters (IPCs) are commonly used to treat pleural effusions (build-up of fluid in the lungs). Doxycycline is an antibiotic that is also used to treat pleural effusions. The goal of this clinical research study is to learn if adding doxycycline to the use of an IPC can lead to shorter treatment times with IPCs.
