Impact of Pre-transplant Anti-fibrotic Therapy for IPF Upon Lung Transplant Outcomes

Study Summary

Two oral medications, nintedanib and pirfenidone, were approved simultaneously by the FDA in October 2014 for the treatment of this disease. They are both considered anti-fibrotic agents and they each proved to slow the progression of disease in their respective clinical trials. Because of their anti-fibrotic properties, there have been concerns about the potential of these medications to impair wound healing following surgery. These concerns have led to variable approaches with respect to the management of the medications in patients listed for lung transplantation. It is unknown whether continuing anti-fibrotic medications until the time of transplant increases the risks of intra-operative and post-transplant complications. Conversely, there are concerns that stopping the medications prematurely may promote a more rapid clinical decline in those awaiting transplantation and increase risk of death while on waiting lists. Whether there is a risk or benefit of continuing the medications during the pre-transplant period deserves investigation with the goal of establishing guidelines and best-practices. Once more is known about how best to manage anti-fibrotic therapy in the pre-transplant period, the question of whether these medications should be restarted following transplantation will also ultimately deserve exploration.

Primary Outcome

The proportions of patients in each group who develop (a) intra-operative outcomes and complications (need for ECMO/cardiopulmonary bypass and blood transfusions) and (b) post-transplant outcomes and complications (mechanical ventilation days, number of days with air leak and chest tube, primary graft dysfunction, anastomotic dehiscence, wound dehiscence, sternal breakdown / dehiscence, post-op infection, post-operative return to OR, blood transfusions) will be calculated.

Interventions
