Unmet Needs with PD Solutions • There do remain some residual unmet needs with traditional PD solutions. ➢ Conventional older PD solutions use o Glucose at concentrations (13.6-42.5 g/L) as the osmotic agent, o Be bioincompatible, which may result in structural changes to the peritoneal membrane with long-term therapy and functional alterations o Other undesirable characteristics, including - acidic pH (5.2-5.5) and - hyperosmolarity (360-511 mOsm/kg) These changes may result in a decline in UF rate and a decrease in dialysis efficiency, leading to poor outcomes Baxter Confidential — Do not distribute without prior approval | 4

Icodextrin: UF Mechanism Osmosis refers to the movement of water across barrier that is permeable to water but restricts the transport of solutes Osmotic Colloid osmotic crystalloid pressure (glucose) pressure (icodextrin) Small molecular weight molecules High molecular weight molecules Fast and important osmotic pressure at Small osmotic pressure at start – slow start, gradual absorption and decrease of absorption – late UF osmotic gradient over time Molecular size is osmotic driving force Peritoneum Interstitium Peritoneum Interstitium GG G G Ico Ico GG G Ico Osmotic flow Osmotic flow G Peritoneal UF = water movement associated to permeable solutes through the peritoneal membrane Osmotic pressure = depends on the number of osmotic active molecules in the solution Reflection coefficient (RC) = Reflection coefficient of Icodextrin is 0.76 as compared to 0.03 of glucose 15
How Icodextrin Works: Colloid Osmosis 16 • Icodextrin - Slow absorption from the peritoneum - Resulting in an almost linear increase in UF during the long-dwell • Glucose-based solutions - Peak UF after a much shorter dwell time - Fast glucose diffusion across the peritoneum and absorption of fluid - Decrease in UF after the net peak UF Mujais et al.

Water moves through the peritoneal membrane through 3 pores, but one type of pore, the aquaporin (AQP), is too small for sodium to move through along with the water. Glucose exchange Icodextrin exchange A Glucose B Icodextrin Crystalloid osmosis (colloid) osmosis The movement of salt and Half of the movement of fluid is water is almost all through through the aquaporins. small pores (SP). Therefore, Therefore, the movement of Na there is no Na sieving with is low, especially at the start of Icodextrin! a dwell (typically the length of an APD dwell). This phenomenon is called Na sieving. 18

Improving PD patient outcomes with APD & RPM 32
Improving PD patients outcome APD: Automated Peritoneal Dialysis Automated Peritoneal dialysis “The better social functioning of APD patients might be related to the fact that daytime for these patients is free • Designed to from treatment, thus facilitating a normal social life.” minimize the burden of frequent de Wit GA, et al. PDI 2001;21:p311. exchanges of dialysate bags • Allow individualized prescription of PD Residual renal function High glucose exposure Fluid overload Solute clearance FOR INTERNAL USE ONLY | Not to be distributed to HCPs
Based on these results, we conclude that; ✓RM-APD has an important role in home dialysis care over time ✓RM permits a tailoring of dialysis treatments and a saving time and costs both for PD patients and PD team
Introduction • PD offers greater patient independence and autonomy compared to in-center HD, with improved quality of life. • However, patient’s adherence to physician’s prescription at home is fundamental for the success of PD • In the home environment, patients may experience a sense of freedom sense of freedom and safety, but they must actively monitor their therapy with daily recording of weight, blood pressure, and fluid removal Milan Manani S, Rosner M, Maria Virzi G, et al.

Definition of Remote Monitoring There are multiple definitions of remote monitoring. • Falls under the umbrella term of “telehealth” or “telemedicine” Telehealth Telemedicine Telecare Patient Remote Teleconsultations Other Monitoring (PRM) (through video conferencing) • Tele-laboratory Telemonitoring • Tele-diagnostics • Clinician to patient • Tele-education Remote Monitoring • Clinician to clinician (RM) Remote monitoring (RM) : technology/ software in the home setting that collects a patient’s clinical data and transmits it to a hospital, physician’s office, clinic, telehealth vendor, or another party who monitors and analyzes the data received. • The RM data may enable clinician to intervene early in the disease management
• Telemedicine (TM) is an innovative tool to provide remote transmission, interpretation, and storage of clinical parameters and useful diagnostic images • Remote monitoring (RM) is a subset of TM where physiological variables or images can be sent to a central monitoring center for review and intervention of the care team. • TM and RM may have important reflections on prognosis, outcomes, and QoL Heart failure, diabetes, and hypertension
RM of patients on APD with this platform offers; • the potential benefits of accurate monitoring of the therapy, • improved patient safety through surveillance of critical stages of the treatment, • early detection of problems, or limited compliance to prescription + the 2-way communication system with interactive interface allows; • a fast trouble shooting: the physicians can change the prescription using the remote connection, • reducing the need for frequent in person visits to the PD center
APD & RPM Platform Upgrade Connectivity Platform ▪ Display : Larger display with 2 lines text, OLED ▪ An innovative, secure, cloud based connectivity platform ▪ Compliant : comply with RoHS, medical device Class II ▪ A two-way, web-based connection between the Homechoice Claria ▪ Memory : keep 90 treatment records in the machine ▪ Language : Add Thai language cycler and the clinic. ▪ Collects and transmits treatment data from the home dialysis device to the clinic ▪ Location AWS secure data servers : Frankfurt For Healthcare Professionals only | 39
• Connectivity platform – no installation required • Treatment data from Homechoice Claria is sent automatically to Sharesource, after the dialysis session • Clinicians can view treatment data and be alerted of problems through programmable flags • Clinicians can change device settings to adjust parameters of next dialysis session • Technical service support (backend) • Provide confidence through complete therapy AWS Secure Data Storage Clinical Portal: visibility by their clinician • More confidence placing and • Conversations with clinician more fruitful, as patient treatment data is accessible through keeping patients on home Clinical portal therapies • Intuitive dashboard with flagged alarms highlighting issues • Potential earlier detection of clinical issues • Access to patient’s historical treatment files • Remote change of device dialysis settings for next therapy sessions For Healthcare Professionals only | 40
Connectivity platform: External Infrastructure Requirements Setting Infrastructure Required Reason/Explanation Clinic/Hospital • Access to the internet Sharesource is a cloud-based Patient’s Home platform, so no additional servers are required at the clinic/hospital. There is no software to install on computers. • Cellular signal/connection Sharesource sends data via a • Cellular modem (provided as a cellular signal (like your mobile phone) so access to the internet/wi- component of the device) fi is NOT required. The modem is also only enabled to send data between Sharesource and the device (i.e. the patient is restricted from using this modem to connect to the internet, etc.)
Summary Remote monitoring Non-compliance Communication Cognitive Anxiety Barriers • Even though optimizing outcomes and adherence from RPM in home dialysis has yet to be proven, evolving the data and case demonstrations support the possibilities that uptake and outcomes of home dialysis can be improved with these technologies • Remote patient management has exciting potential to improve home dialysis patient care and home modalities uptake, to improve quality of life, and to reduce cost Krishna, EL, et al.
