Plain-language summary
The Second Investigation of the Management of Pericarditis (IMPI-2) Trial will compare the effectiveness and safety of complete percutaneous pericardial drainage facilitated by intrapericardial alteplase (recombinant human tissue-type plasminogen activator) to conventional pericardiocentesis when indicated in 2176 patients with large pericardial effusion due to tuberculous and non-tuberculous pericarditis. An internal pilot study of 218 patients will initially confirm the feasibility of conducting a large-scale multi-centre clinical trial of intrapericardial fibrinolysis in patients with large pericardial effusion, and also provide preliminary safety data, following a dose finding study of intrapericardial alteplase.

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Composite outcome of cardiac tamponade requiring pericardiocentesis or constrictive pericarditis.
. Thrombocytopenia (i.e., \< 100,000 platelets per µl);
. Presence of a contra-indication to the administration of a fibrinolytic agent (i.e., major haemorrhage or major trauma; coincidental stroke; major surgery in the previous 5 days; blood pressure \>200/100 mmHg).
