Comparing two methods for treating malignant pleural effusion

The Australasian Malignant PLeural Effusion (AMPLE) Trial - 3: A Randomised Study of the Relative Benefits of Combined Indwelling Pleural Catheter (IPC) and Talc Pleurodesis Therapy or Video-Assisted Thoracoscopic Surgery (VATS) in the Management of Patients With Malignant Pleural Effusion.

NA · The University of Western Australia · NCT04322136

This study is testing whether a long-term catheter or surgery works better for helping people with fluid buildup in the lungs due to cancer feel better and breathe easier.

What this trial studies

This study aims to evaluate the effectiveness of an indwelling pleural catheter versus surgical pleurodesis in managing malignant pleural effusion. Participants will be randomly assigned to one of two treatment arms: one receiving a long-term catheter for home drainage and the other undergoing video-assisted thoracoscopic surgery. The study will monitor participants' quality of life and clinical outcomes over a year, with follow-up assessments at various intervals. The goal is to determine which method provides better symptom relief and lung function restoration.

Who should consider this trial

Good fit: Ideal candidates are adults with symptomatic malignant pleural effusion and a predicted survival of more than six months.

Not a fit: Patients who are under 18 years old, unfit for surgery, or have certain medical conditions like pleural infection or chylothorax may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective and less invasive treatment option for managing malignant pleural effusion.

How similar studies have performed: Other studies have shown promising results with similar approaches, indicating potential for success in this trial.
