Safer liver resection: Perioperative assessment of liver function with the LiMAx® test shortens hospital stay and reduces complications after liver surgery

Clinical phase III trial at 6 specialized liver centers demonstrates impressive benefits of the LiMAx® test

Berlin, Germany, July 25, 2018 – Humedics GmbH, a specialist in real-time measurement of liver function capacity, announced results of a multicenter randomized controlled clinical trial that clearly shows the benefits of the LiMAx® test in liver surgery. Perioperative use of the LiMAx® test shortens hospital stay by 3 days and significantly reduces the incidence of severe complications after liver surgery.

 

Liver resection is a common treatment for patients with liver tumors. However, liver surgery bears a high risk of postoperative liver failure and death. Due to the lack of accurate diagnostic tests to predict the individual patient outcome, the current conservative standard of care proposes a postoperative transfer of patients to the intensive care unit (ICU). With the LiMAx® test, Humedics provides a solution that bridges the existing diagnostic gap as the test allows for real-time quantification of the liver function and thus for optimized surgery planning and patient management.

 

Humedics executed a randomized controlled phase III clinical trial to evaluate the clinical impact of perioperative liver function assessment with the LiMAx® test on early postoperative patient outcome and patient management after liver resection. Study results clearly demonstrate that the LiMAx® test shortens the length of stay in the ICU and the hospital overall, and it reduces the incidence of severe complications after liver surgery. In contrast to the currently common and cost-intensive practice of a mandatory stay in the ICU, 62 percent of the patients in the LiMAx® group (58 patients in total) did not require a stay in the ICU after surgery because postoperative LiMAx® indicated the presence of sufficient functional liver capacity to enable rapid recovery without complications. 10 percent of the LiMAx® group were transferred to an intensive care unit due to critically low LiMAx® values (150 μg per kg per h or less) and another 28 percent due to non-liver related complications. In the control group, only one out of 60 patients (2 percent) was immediately referred to a general ward. Postoperative severe complications were significantly lower in the LiMAx® group as well, with 14 percent, versus 28 percent in the control group. Both, the length of ICU stay and the length of the overall hospital stay, were significantly shorter in the LiMAx® group compared to the control group.

 

Karsten Damgaard-Iversen, CEO of Humedics GmbH, stated: “Following a retrospective analysis of our early experience with the LiMAx® test in liver surgery, which already showed a striking decrease in postoperative liver failure when the LiMAx® test was used, we initiated this clinical trial to further evaluate and document the impact of the LiMAx® test on postoperative patient outcome, as well as on safe and cost-effective patient management. The results of this clinical trial have clearly demonstrated the unique benefits of the LiMAx® liver function capacity test in this setting, but in addition, we are also confident that these results will help us convince clinicians and hospital administrators to adopt a broader utilization of our test. Not only in the context of liver surgery, but across the space of liver disease management and diagnosis in oncology and hepatology.”

 

Erwin de Buijzer, COO of Humedics, further commented: “The unparalleled results show the impact of the LiMAx® test in clinical routine. Whenever the LiMAx® system is implemented, the liver surgeons and hepatologists realize the unprecedented value of the test for their clinical decision making. It is evident that the health economic benefits of using the test as a result of the complication reduction and shorter length of stay contribute significantly to cost containment in the healthcare environment.”

 

Study details

The primary endpoint of the study was the direct transfer of patients from the recovery room to a general ward (instead of transfer to intensive care unit and regular discharge from hospital maximally 30 days after surgery). Secondary study endpoints included the development of postoperative liver failure and severe complications.

A total of 148 patients with liver tumors scheduled for open liver resection were recruited at six German academic centers specialized in complex liver surgery. Patients were randomized equally in two study arms, either to the intervention arm (LiMAx® group) or to the standard-care arm (control group). In the intervention group, two LiMAx® test assessments were performed in patients: The first one the day before surgery – for individual surgical planning. The second one was done within 6 h after surgery – to determine the individual patient’s postoperative management. In the control group, perioperative management followed standard clinical care without performing a LiMAx® test. A total of 118 patients, 58 in the LiMAx® group and 60 in the control group, were eligible for analysis.

About Humedics

Based in Berlin, Germany, Humedics GmbH is specialised in rapid and accurate liver function measurement using LiMAx®, an innovative technology for analysing exhaled air. The LiMAx® test provides physicians with a method for quantitatively assessing an individual patient’s liver function capacity within minutes. This enables physicians to select treatment strategies and follow disease progression based on up-to-date knowledge of the functional health of the liver. Current applications, which have already been published in prestigious medical journals, include liver function diagnosis before and after liver transplantation, surgical planning for liver surgery (such as assessing how much liver tissue can be removed without increasing the risk of acute liver failure), and assessment of liver diseases such as fibrosis and cirrhosis.  At present, more than 20 studies regarding new indications are being conducted. These include diagnosing and staging of chronic liver diseases such as non-alcoholic steatohepatitis (NASH), as well as selecting, monitoring and managing different oncology treatment options. These studies, initiated by researchers, have already provided evidence of further potential for the LiMAx® tests. The LiMAx® test is in routine clinical use at more than 30 leading university hospitals in Europe. So far, more than 20,000 LiMAx® tests have been performed. The LiMAx® test is commercially available in Germany, Austria and the UK.
