Tulane starts a prospective trial of XM-ONE® in Kidney Transplantation.

Tulane University Hospital, New Orleans, LA, USA will in May start a prospective
trial in Kidney Transplantation investigating the potential of cross match XM
-ONE® as part of the risk assessment of their patients.
“It is our belief that patients at higher risk for rejection can be identified
using XM-ONE® technology” says Professor Joseph Buell, chief of surgery at
Tulane. “Earlier identification of at risk patients prior to a clinically
relevant rejection will allow us to modify our surveillance program and
immunosuppression. In order to evaluate the potential of this test within our
traditionally challenging population we started a baseline evaluation of XM
-ONE®”, he continues.

The study at Tulane will include 50 contiguous Caucasian and 50 contiguous
African American renal transplant recipients and the patients will be tested
with XM-ONE® both before transplantation and at a follow-up 6 months post
transplantation.

“This is clearly encouraging for us”, says Anders Karlsson, CEO of Allenex. “It
further strengthens our belief that XM-ONE® has a role in the pre transplant
risk assessment. The initiative of Prof. Buell and the transplant team at Tulane
to also include post-transplant evaluation to the repertoire makes this even
more exciting”, he ends.

About Tulane University
Traditionally Tulane University has cared for a challenging end stage renal
failure population. The program currently performs 100 renal transplants a year,
with African American population in excess of 65%. Tulane recipients are often
at increased immunologic risk; namely a high PRA (>30) 20% and re transplants
(about 10%). In their patient population they have identified a significantly
higher incidence of rejection and antibody mediated rejection.
