Indwelling Pleural Catheter With Either Doxycycline or Saline at Day 7 for Pleurodesis

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical research study is to compare indwelling pleural catheters (IPC) in combination with saline (the current standard of care) versus IPC in combination with doxycycline as treatment for pleural effusions.

Detailed Description
-----------------
IPC Placement and Placement Follow-Up: Before the IPC is inserted, you will complete 2 questionnaires about your quality of life and any symptoms you may have. It should take no more than 15-20 minutes to complete. You will also have a chest x-ray and you will rate your pain on a scale of 1-10. These tests are all part of your standard of care and can be explained to you in more detail by your doctor. You will be required to sign a separate consent form in order to have the IPC placed. Your doctor will give you detailed instructions about the IPC placement procedure, including its risks. After the IPC is placed, the doctor will give you a prescription for a fentanyl patch to help control pain. The study staff will tell you how and when to wear the fentanyl patch and about any side effects that are associated with fentanyl. About 5 days (+/- 2 days) after the IPC has been placed, you will have a clinic visit where you will be checked up on as part of your standard of care. It is important that you wear your fentanyl patch in the morning before this visit. At this clinic visit, the results of a previously performed chest x-ray will be reviewed, you will be asked to rate your pain on a scale of 1-10, and you will be asked how much fluid has drained from your catheter. Based on the results of the above Day 5 check-up, if you are found to be ineligible to receive the study drug, the fentanyl patch will be taken off and you will be followed as part of your usual care. However, you will still considered to be on study and you will be followed the same as a participant who receives the study drug. If you are found to be eligible to receive the study drug, you will receive fentanyl by vein over a few minutes, if needed to help control your pain. The study staff will then begin to drain your catheter and either doxycycline or saline (described below) will be placed in the catheter. The catheter will be capped for 1 hour and then drained again. To determine if you will receive doxycycline or saline, you will be randomly assigned (as in the flip of a coin) to 1 of 2 study groups. This is done because no one knows if one study group is better, the same, or worse than the other group. If you are in Group 1, you will receive doxycycline. If you are in Group 2, you will receive saline. Neither you nor the study doctor will know if you are receiving doxycycline or saline. However, if needed for your safety, the study staff will be able to find out what you are receiving. Length of Study Participation: You will receive doxycycline or saline 1 time on this study. Your participation on this study will be over if you withdraw consent or the study closes, whichever takes place first. Follow-Up: Between 10-14 days after you have received either doxycycline or saline, you will come to the clinic as part of your usual standard of care so the doctor can check your IPC for possible leaking, infection, to see how much fluid has drained, and to remove any sutures. The catheter may be removed if you have it is leaking or shows signs of infection. You will continue to have this visit 1 time each month as part of your standard of care until the catheter is removed. During each of these visits: You will have a chest x-ray to check the status of your lungs. You will complete the same 2 questionnaires that you completed before your IPC was placed. Long-Term Follow-Up: One (1) time each month after the IPC is removed, you will be called and asked how you are doing, if you are having any side effects, if the disease has come back, and about your overall quality of life. Some of this information may be collected from your medical record. Each phone call should last about 5-10 minutes. This is an investigational study. Doxycycline is FDA approved and commercially available for the treatment of different types of infections and pleural effusions. It is considered investigational to compare doxycycline to saline to treat pleural effusions. Up to 250 participants will take part in this study. All will be enrolled at MD Anderson.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Primary Outcomes of Interest Will be Time to Catheter Removal. | This outcome will be analyzed by cause-specific hazard Cox model with treatment group as a covariate. Whenever a catheter is removed the cause for removal will be documented. For the analysis causes will include removal due to decreased drainage (i.e. as per plan) as well as removal due to complications (e.g. infection, empyema, and refractory pain) or other reasons (e.g. catheter plugged but no complication to the patient, patient preference without a complication). | 1 month |
