THE NEXT HORIZON IN DIALYSISIS CLOSER THAN YOU THINKHDx BY THERANOVA EXPANDS YOUR RENAL POSSIBILITIES

The new HDx therapy (expanded HD) is the next evolution in hemodialysis, as it effectively targets the removal of large middle molecules.1 Indeed, many of them are linked to the development of inflammation, cardiovascular disease, and other co-morbidities in dialysis patients.2

Not only can HDx therapy provide HDF performance and beyond in the removal of conventional middle and large middle molecules, it does so using regular HD workflow and infrastructure.3

The HDx therapy is enabled by the THERANOVA* dialyzer featuring an innovative membrane that combines a higher permeability than regular high-flux dialyzers with effective selectivity for large proteins.4,5

This new therapy opens up a new option for dialysis patients who are believed to benefit from effective removal of large uremic toxins, for clinics that want expanded dialysis performance without the added burden of HDF.

CHANGE ONE THINGCHANGE EVERYTHINGEXPLORE THE HDx THERAPY BY THERANOVA

Mortality from cardiovascular and infectious events in HD remains unsatisfactorily high with current dialytic therapies.6 Large middle molecules have been associated with inflammation, cardiovascular events and other dialysis-related comorbidities.2 Current dialytic therapies, though efficient in removing small solutes, have limited capability in removing large middle molecules.7

HDx is a new therapy targetting an efficient removal of large middle molecules, without the need for a more complex setup than in regular HD. The HDx therapy is delivered with an innovative dialyzer featuring a new type of membrane, combining a higher permeability than high-flux dialyzers with effective selectivity to retain essential proteins.4,5

CATEGORIZATION OF UREMIC SOLUTES Non-protein bound uremic solutes accumulating in chronic kidney disease can be divided into three main categories.5

Small molecules < 500 DaEffective removal by diffusion

Conventional middle molecules 500 - 15,000 DaLimited removal by diffusion, compensated by applying convection

Large middle molecules 15,000 - 60,000 DaRequire higher permeability membranes for effective removal

There is growing evidence showing a link between large middle molecules and the development of different outcome-related morbidities:

Complement factor D (24 kDa)

α1-microglobulin (33 kDa)

YKL-40 (40 kDa)

Immunoglobulin Free Light Chains (22.5 and 45 kDa)

More than the specific impact that each and every large middle molecule may have on the health of chronic kidney disease patients, it is critical to understand and address their collective effect. Uremia related to the retention of large middle molecules is indeed associated with inflammation and cardiovascular events.8,9,10

LARGE MIDDLE MOLECULES ARE ASSOCIATED WITH INFLAMMATION AND CARDIOVASCULAR EVENTS

A STEP CLOSER TOTHE NATURAL KIDNEYTURNING INNOVATIVE DESIGN INTO A CLINICAL SOLUTION

The THERANOVA dialyzer enables the HDx therapy by combining 4 therapeutic principles: permeability, selectivity, retention and internal filtration – into a single dialyzer design.

Its innovative medium cut-off (MCO) membrane expands the range of solutes removed during regular dialysis, while retaining essential proteins at a safe and controlled level. This unique cut-off and retention onset profile allows for filtration close to that of the natural kidney.4,5

HIGHER PERMEABILITYWith an increased nominal pore size, the THERANOVA dialyzer has a significantly higher permeability for large middle molecules compared to regular high-flux membranes, before and after blood contact.

EFFECTIVE SELECTIVITY FOR LARGE PROTEINSBy combining a unique asymmetric 3-layer structure with a carefully controlled distribution of the pore size, the THERANOVA dialyzer enables a stable separation profile and selectivity throughout the treatment, keeping albumin removal at a controlled level.

RETENTIONThe adsorption properties of the THERANOVA membrane maintain the same level of bacteria and endotoxin retention as other standard dialysis membranes.11 Despite its higher permeability, the THERANOVA membrane appears to be a safe and effective barrier to potential dialysis fluid contaminants. It is compatible with standard fluid quality (ISO 11663:2014) and does not require any additional fluid quality control measure.12

INTERNAL FILTRATIONThe inner diameter of the THERANOVA membrane has been carefully reduced in order to increase internal filtration along the membrane, conducive to an enhanced removal of large middle molecules.

TREATMENT EFFECTS AND THERAPY IMPLICATIONS (VS. HD)3

HD therapies have been the treatment of choice for many years — both for many patients and many clinics. The design and operating mode of the THERANOVA dialyzer enables the HDx therapy to be easily implemented on any HD monitor.13 This means by simply changing the dialyzer, any clinic can provide markedly greater clearances and intradialytic reduction ratios than regular HD – at ordinary blood flow rates.

TREATMENT EFFECTS AND THERAPY IMPLICATIONS (VS. HDF)3

HDx therapy enabled by the THERANOVA dialyzer provides an equivalent removal of small and conventional middle molecules, with the possibility of greater removal for large middle molecules when compared to high-volume HDF. HDx performance can be achieved in all regular HD environments: this simplicity removes the potential burden of patient eligibility or therapy specific delivery systems.
