Performance Evaluation of the AMIA APD Solution Generation System in Patients End Stage Renal Disease (ESRD)

Not Applicable

Terminated

Conditions: End Stage Renal Disease (ESRD)

Interventions: Device: AMIA APD Solution Generation System

Registration Number: NCT03812679

Lead Sponsor: Vantive Health LLC

Brief Summary: Peritoneal dialysis (PD) is a well-established treatment for renal failure including long-term management of end stage renal disease (ESRD) by continuous ambulatory peritoneal dialysis or automated peritoneal dialysis (APD).

Complementary therapies offer longer term survival for patients with ESRD. However, none of them are devoid of side effects and today their limitations are better understood by the nephrologist.

The AMIA APD Solution Generation System combines an updated AMIA APD Cycler with Sharesource Platform (previously cleared) with an in-home water system technology and leverages newly developed AMIA APD Concentrates.

The AMIA APD Concentrates, after dilution by the AMIA APD Solution Generation System, are indicated for adult patients in acute or chronic renal failure when non-dialytic medical therapy is judged to be inadequate.

Women of childbearing potential (not menopausal or surgically sterile) must not be pregnant. Serum qualitative and quantitative pregnancy test will be done within 14 days prior to initiation of study product.
- If qualitative serum β-hCG results are positive, repeat quantitative serum pregnancy test in 48 hours.
- If quantitative serum β-hCG levels show clinically significant rise within 48 hours, serum progesterone level should be taken. Serum progesterone > 5 ng/mL will exclude a patient from the study.
Sexually active males and females agree to use a reliable means of contraception during the study and for 30 days afterwards (e.g., oral contraceptive and condom, intrauterine device and condom, or diaphragm with spermicide and condom).

Patient who has a severe primary immune deficiency or other condition that may mask clinical signs of peritonitis, as evaluated by the Investigator.
Patient with a history of repeated non-compliance with PD, therapy (e.g., a substantial number of missed clinic visits, missed treatments or a history of mismanagement of diet or medications), as evaluated by the Investigator.
Patient who has acute renal failure with the chance for recovery.
Patient who is pre-scheduled for a living donor kidney transplant within the next 6 months.
Patient who is not expected to live at least 6 months while maintaining PD treatment.
Patient who had major abdominal surgery within 6 months prior to study enrollment.
Patient with current abdominal hernia, as evaluated by the Investigator.
Patient with advanced liver or pulmonary disease, as evaluated by the Investigator.
Positive serology test for Hepatitis B Virus or Hepatitis C Virus infection, or aspartate transaminase or alanine aminotransferase > 3 x upper limit of normal at Screening.
Patient with diagnosed stage III or IV New York Heart Association (NYHA) heart failure.
Patient who has an active malignancy.
History of a clinically significant illness and/or clinically significant surgery within the past 14 days preceding the Screening Visit as determined by the Investigator.
Patient who is enrolled in another interventional clinical study.

Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
AMIA APD Solution Generation System	AMIA APD Solution Generation System	A simulated treatment will take place before the patient receives study treatment, during week 1 and after 4, 8 and 12 weeks of study treatment period. The dialysis solution generated by the simulated treatment will be collected from the system in the heater bag and used to evaluate the chemical composition of the final dialysis solution produced by patients using the AMIA APD Solution Generation System. Also, product water from the Water Device (pre-sterilizing filters) will be collected and tested at each visit.

Primary Outcome Measures

Name	Time	Method
Percentage of Tests Meeting Specifications for the Chemical Composition of Final Dialysis Solution by Visit	Week 1, 4, 8 and 12	The dialysis solution generated by the simulated treatment will be sampled from the heater bag, compared to the specifications of Baxter's approved low calcium Dianeal PD solution. The following 9 test methods will be analyzed: pH at 25 C, Color, 5- (hydroxymethyl)furfural (5HMF), Dextrose hydrous Assay (1.5%, 2.5% or 4.25%), Sodium Lactate Assay, Sodium Assay, Chloride Assay, Magnesium Chloride Hexahydrate (MgCl2.6H2O) Assay, and Calcium Chloride Dihydrate (CaCl2.2H2O) Assay. Measurements were collected using instruments such as meters, chromatography, etc. Data will be reported showing percentage of participants meeting specifications versus percentage of participants not meeting specification. If any one of the values falls outside the limits, then the particular test is considered NOT meeting specifications.
Percentage of Tests Meeting Specifications for the Microbiological and Chemical Testing of Product Water From Water Device (Pre-sterilizing Filters) by Visit	Week 1, 4, 8 and 12	Microbiological testing within \<=0 CFU/mL limit for total aerobic microbial count (TAMC) and total yeast/mold count (TYMC) and \<0.03 EU/mL limit for Endotoxins, and chemical parameters. Product water from the WD (pre-sterilizing filters) was collected and tested for microbiological (including endotoxin) contamination per USP \<61\> and USP \<85\> and chemical contaminants according to ISO 13959. Chemical parameters include aluminum, copper, fluoride, lead, nitrate, sulphate, zinc, calcium, magnesium, potassium, sodium, antimony, arsenic, barium, beryllium, cadmium, chromium, mercury, selenium, silver, thallium, nickel, cobalt, total chlorine. Chemical measurements were collected using instruments such as meters, chromatography, etc. Data will be reported showing percentage of participants meeting specifications versus percentage of participants not meeting specification. If any one of the values falls outside the limits, then the particular test is considered NOT meeting specifications.
Percentage of Tests Meeting Specifications for the Microbiological Testing of Product Water From Holding Bag (Post-sterilizing Filters) by Visit	Week 1, 4, 8 and 12	Microbiological testing within \<=0 CFU/mL limit for TAMC and TYMC and \<0.03 EU/mL limit for Endotoxins. Data will be reported showing percentage of participants meeting specifications versus percentage of participants not meeting specification. If any one of the values falls outside the limits, then the particular test is considered NOT meeting specifications. A test was considered as meeting specifications if all of the following parameters fell within the specified limits: tryptic soy broth growth, fluid thioglycolate growth, and endotoxins. Water in the holding bag was collected and tested for microbiological contamination and endotoxin levels per USP \<71\> and USP \<85\>.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Total Kt/Vurea at Week 5, 6, 7, or 8	Baseline, Week 5 or Week 6 or Week 7 or Week 8	Peritoneal dialysis adequacy will be measured by sample collection and calculation of Total Kt/Vurea. Weekly peritoneal Kt/Vurea was calculated from blood and 24-hour PD effluent samples and renal Kt/Vurea was calculated from 24-hour collection of urine samples (if applicable) and blood samples after the patient had been dialyzing with the AMIA APD Solution Generation System for at least 4 weeks. Total Kt/Vurea is the sum of peritoneal Kt/Vurea and renal Kt/Vurea. Note: This secondary efficacy endpoint was measured by sample collection and calculation of total Kt/Vurea, occurring one time during Week 5, 6, 7, or 8 of the Study Treatment Period.
