Mallinckrodt Initiates Proof-of-Concept Study of Nitric Oxide Gas in Ex-Vivo System of Human Lung Transplants

STAINES-UPON-THAMES, United Kingdom, Aug. 1, 2018 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today announced it has initiated a company-sponsored, experimental, proof-of-concept study of nitric oxide gas with ex-vivo lung perfusion compared to lung perfusion alone in human lung transplants. The study has enrolled its first set of lungs, and the actual lungs to be evaluated are being assigned for research use, not for human lung transplantation.

The study's primary objectives are to assess the effects of nitric oxide in perfused ex-vivo lungs using a proprietary grading system and to evaluate the total ex-vivo perfusion time of the lungs through periodic assessments during Ex-Vivo Lung Perfusion (EVLP).

EVLP describes a process of evaluating and preparing donor lungs outside the body; nutrients are perfused, or circulated, through the organ, and the organ is ventilated to mimic physiologic function prior to transplant surgery. EVLP has the potential to increase the available donor pool through restoring and repairing donor lungs.¹

"Mallinckrodt is focused on providing treatment options for the unmet needs of and to improve outcomes for patients with severe and critical conditions. The company has more than 20 years of experience with and investment in nitric oxide as a signaling molecule," said Steven Romano, MD, Executive Vice President and Chief Scientific Officer at Mallinckrodt. "We are pleased to begin and learn from this important research evaluating nitric oxide gas for potential use in lung transplantation as the company seeks to establish and grow its presence in this therapeutic area."  

About the Study
This proof-of-concept randomized, multicenter, blinded study will assess the effects of nitric oxide in modified criteria human lung transplants via EVLP. It is planned to be conducted at four major U.S. lung transplant centers through the fourth quarter of 2018. The study will evaluate extended criteria bilateral donor lungs, not suitable for lung transplantation. Upon a successful proof-of-concept study, the company expects to initiate a safety study to assess use of nitric oxide in human lung transplantation in 2019.

About Lung Transplantation in Humans
In the U.S. each year, about 2,000 people receive a lung transplant² – the surgical replacement of either a single or two (double) badly diseased lungs with healthy lungs from a human organ donor. A variety of diseases and conditions can damage a person's lungs and hinder their ability to function effectively, such as chronic obstructive pulmonary disease (COPD) including emphysema; scarring of the lungs; pulmonary fibrosis; cystic fibrosis; sarcoidosis; and pulmonary hypertension.³ A major limiting factor to the number of transplants performed is donor lung shortage.⁴ According to Organ Procurement Transplant Network data, approximately 1,400 patients with severe lung disease are on the waiting list for a transplant.⁵
