The results of an extensive clinical study presented at the 44th ISHLT Annual Meeting and Scientific Sessions comparing conventional ice storage to the Paragonix LUNGguard system. The analysis revealed that advanced lung preservation technology with the Paragonix LUNGguard favorably influences post-transplant outcomes, including reductions in primary graft dysfunction, the use of invasive MCS interventions, and improvement in renal function.

The GUARDIAN-Lung data was collected from August 2018 through January 2024, including 797 patients (389 ice storage patients, 408 LUNGguard patients), of which 259 subjects were identified as statistical matches based on a propensity matching methodology.

Investigators discovered notable statistically significant improvements in the controlled hypothermic preservation group, including:

• 38% reduction of Primary Graft Dysfunction 3 (PGD 3) at 24 hours (12.7% LUNGguard vs. 20.5% Ice, p = 0.024)¹
• 39% reduction of Extracorporeal Membrane Oxygenation (ECMO) post-transplant (11.6% LUNGguard vs. 18.9% Ice, p = 0.027)¹
• 51% reduction in need for dialysis at discharge (5.5% LUNGguard vs. 11.2% Ice, p = 0.025)¹‍

Further, a numerical reduction in primary graft dysfunction at 72 hours, an indication of severe post-transplant complications, was also observed in the LUNGguard group (9.7% LUNGguard vs. 15.4% Ice, p = 0.063).¹
