All patients included in the NOVEL trial in the USA with STEEN Solution™

In June all the patients were included in the clinical study with STEEN
SolutionÔ according to plan. Interim results confirms previous single center
experience, that initially rejected lungs evaluated with Ex Vivo Lung Perfusion
(EVLP) perform similarly to standard criteria lungs after transplantation and
that the use of EVLP to screen the marginal donor pool is safe. The patients
will be followed up for one year after transplantation.
The NOVEL trial is a multicenter study performed at 6 sites in USA and was
designed to safely increase the percentage of usable lungs from the donor pool.
In the study, clinical outcomes associated with ex-vivo lung perfusion (EVLP) of
initially rejected or marginal lungs were compared with contemporary matched
controls. A total of 42 patients received transplants using the STEEN Solution™
method and was matched with 42 control patients. The initial results indicate
that initially rejected lungs that were perfused with Steen Solution™ perform as
well as lungs that initially were deemed good for use. This is in line with
experiences from centers in Europe and Canada where EVLP with STEEN Solution™ is
in clinical practice.

At the International Society of Heart and Lung Transplantation (ISHLT)
conference in Montréal, the interim results were presented and confirmed
previous single center experiences that initially rejected lungs evaluated with
Ex Vivo Lung Perfusion (EVLP) perform similarly to standard criteria lungs after
transplantation. The results also indicate that the use of EVLP to screen the
marginal donor pool is safe. At the same conference, the combined outcome data
from Toronto (Canada), Vienna (Austria) and Paris (France) were presented with
140 assessed and 114 transplanted lungs. More than 240 patients have now
received lungs evaluated with STEEN Solution™ method which would have otherwise
remained unused without this technology.

“The clinical results from the study are very encouraging and demonstrates that
STEEN Solution™ safely makes many more organs available for this life-saving
treatment of patients with end-stage lung deceases” says Dr Magnus Nilsson, CEO
of XVIVO Perfusion.
