About this study
Official title: Impact of a Continuous Dialysis Technique Associated With Adsorption Capacity Membranes in Patients With Sepsis Associated - Acute Kidney Injury.
Septic patients with acute kidney injury (SA-AKI) requiring continuous renal replacement therapies (CRRT) present high mortality due to systemic inflammatory response, cytokine liberation, and finally multiorgan dysfunction. Cytokine plasmatic elimination with continuous venovenous hemofiltration (CVVH) presents frequent complications, known as "dialytrauma", and a high resource cost both technical and human. The study primary end-point is to demonstrate a longer filter life with the use of continuous venovenous hemodialysis (CVVHD) respect to CVVH, both modalities employing the same adsorption capacity membrane. As secondary end-points investigators will try to demonstrate less dialytrauma events of CVVHD respect to CVVH. In order to achieve these objectives investigators have designed a proof of concept exploratory trial that will include those patients whom present SA-AKI meeting CRRT initiation criteria. During the first 72 hours investigators will measure plasmatic elimination capacity of main cytokines, and other clinical and prognostic relevant molecules. Investigators will also measure hemodynamic, respiratory, and metabolic parameters. Adverse effects related to CRRT ("dialytrauma") will also be registrated. Finally, investigators will analyze 90 days survival. Demonstration of a minor complication rate (longer filter patency with less dialytrauma events) with a similar immunomodulating capacity and with its consequent lower cost, should settle the based evidence principles that recommend the use of CVVHD asociated to an adsorption capacity membrane in patients with SA-AKI whom need CRRT.
Read the detailed description
Investigators will warrant a correct protocol application. Study data will be reviewed by an external monitoring committee from the clinical assay research central unit (UCICEC - IDIBELL). Monitors will contrast registered data from the collection data form (CDF) with data from patient´s medical record. All patient´s medical records will be indefinitely saved in electronical format to be reviewed if necessary.
Patients who meet inclusion criteria will be randomized for one of both arms with aleatory assignation using a randomisation sequential (RndSeq) program for Statistical Package for the Social Sciences (SPSS). Adverse events will be reported (in less than 24 hours if severe) to the sponsor center to be properly evaluated. If the severe adverse event (SAE) is finally evaluated by the study board as related to the intervention arm, urgent notification to health authorities must proceed and study should be interrupted until further decision.
As a pilot study of at least 50 cases is advisable in many circumstances (Sim and Lewis, 2012), and we wanted to compare two treatment options, we aimed to recruit at least 100 patients.
Missing data will try to be avoided by an exhaustive patient´s follow up by study investigators. Intention to treat analysis (ITT) will be the main strategy and statistical substitution techniques for missing data will be applied when necessary. Per protocol analysis will also be done to avoid possible bias. Out-of-range results will be identified and processed with adequate statistical techniques.
Data registry has been created to include all variables with written individual data collection forms (DCF). Data will be bedside registered by the study members but final software database registration will be done by the statistics outside investigator who has no contact with patients situation. Cytokines levels will be introduced in DCF when measured (every six months).
Statistical analysis will be done by the statistics investigator who wont have any role in patient´s selection, randomization, or follow up. SPSS v. 18.0 for statistical analysis will be used. Variable distribution will be studied and logarithmic transformation will be used on those variables that don't present normal distribution, presumably cytokine levels. Univariate analysis comparing clinical, demographic, biochemical, metabolic, hemodynamic and respiratory baseline variables between both arms (CVVHD-ST150 and CVVH-ST150), will be done with two-tailed t test for continuous variables and chi-square test for categorical variables. Variables determined several times (T0, T24, T48, T72) will be analysed using a one-way repeated measures ANOVA test in order to demonstrate differences between both arms. Multivariate analysis will be completed to control those clinically relevant confounding variables as well as to discover baseline differences. According to hypothesis and to the dependent variable on study investigators will use a survival analysis (to study mortality) with a cox regression model, or a hierarchic multiple linear regression model when the dependent variable is continuous (for example dialytrauma score). Arm intervention (CVVHD, CVVH) will be considered as the main independent variable adding other control independent variables.
As the study is measuring cytokine levels in five different moments (T0, T24, T48, T72), in order to maximize statistical power and reduce control variables number, the area under the curve (AUC) we´ll be determined for every cytokine and LPS during the first 72 hours. Due to this statistical maneuver investigators will obtain a continuous variable that represents each cytokine level during the biochemical study period (72 hours). To evaluate if the arm intervention improvement in terms of efficacy and safety could be related to cytokine levels during the first 72 hours, a mediation complementary analysis will be done considering cytokine (represented by AUC) as a mediator between the independent variable (intervention arm) and the effect we study.

CVVHDOther
Also called Continuous venovenous hemodialysis
CVVHD will be used during 72 hours with a prescribed dose of 30 ml/Kg/h Prismasol® 4 as dialysate fluid. Blood flow of 200-250 ml/min, to achieve 12 - 15 L/h will be prescribed. Isovolemic CRRT will be encouraged during this 72 hours if volume overload status is not present. After 72 hours, CVVHD will be continued and dialysate dose (ml/kg/h) will be adjusted to achieve creatinine levels between 80-120 umol/L until patient recovers urine output and / or tolerates intermittent hemodialysis.
CVVHOther
Also called Continuous venovenous hemofiltration
CVVH will be used during 72 hours with a prescribed dose of 30 ml/Kg/h Prismasol® 4 as reposition fluid. Blood flow of 200-250 ml/min, to achieve 12 - 15 L/h will be prescribed adjusting the adequate percentage of prefilter reinfusion to maintain a theorical filtration fraction between 18-22%. Isovolemic CRRT will be encouraged if volume overload status is not present. After 72 hours, CVVH will be continued and filtration dose (ml/kg/h) will be adjusted to achieve creatinine levels between 80-120 umol/L until patient recovers urine output and / or tolerates intermittent hemodialysis.

What is being measured
The primary outcome is the main question the study is designed to answer.
Technical CRRT efficiency
Number of times set was changed.
Measured: 72 hours
Secondary outcomes (6)
Safety technical superiority.
Less adverse events related to CRRT known as "dialytrauma". Red blood cells transfusions related with filter clotting, thrombocytopenia (less than 100.000), hypophosphatemia (less than 0.7 mmol/L), hypokaliemia (less than 3.3 mmol/L), and hypothermia (less than 35.5ºC rectal temperature).
Measured: 72 hours
Survival at 90 days after randomization
Kaplan Meyer survival analysis and cox proportional hazard ratio for death will be both done at 90 days after CRRT initiation.
Measured: 90 days.
Immunomodulating capacity
Cytokine removal: interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), interleukin-4 (IL-4), and interleukin-10 (IL-10) levels will be determined in plasma (pre and postfilter) and in ultrafiltrate.
Determinations will be measured baseline (0hours), and at times 24hours, 48hours, and 72hours. 24h, 48h, and 72h determinations should only be done when ST150 set has been working for at least 6 continuous hours. This means that determinations can be advanced or delayed +/- 4 hours to scheduled time (for example 20 - 28 hours for T24).
Measured: 72 hours
Renal depuration capacity.
Sieving coefficients for plasma solutes (creatinine, urea, potassium, albumine, magnesium, phosphate, and others) will be determined after measuring blood (pre and postfilter) and ultrafiltrate levels at 24hours, 48 hours, and 72 hours. 24h, 48h, and 72h determinations should only be done when ST150 set has been working for at least 6 continuous hours. This means that determinations can be advanced or delayed +/- 4 hours to scheduled time (for example 20 - 28 hours for T24).
Measured: 72 hours.
Hemodynamics and respiratory variations.
Hemodynamic and respiratory parameters will be registered every hour. Arterial and venous gasometries with arterial lactate will be determined every 6 hours during the first 72 hours.
Measured: 72 hours.
Clinical efficiency
Days on CRRT. Days on Dialysis. Days of ICU. Days of hospital. Renal recovery at hospital discharge (free from dialysis).
Measured: 90 days

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Septic patients with acute kidney injury (SA-AKI) requiring continuous renal replacement therapies (CRRT) present high mortality due to systemic inflammatory response, cytokine liberation, and finally multiorgan dysfunction.

Blood flow of 200-250 ml/min, to achieve 12 - 15 L/h will be prescribed adjusting the adequate percentage of prefilter reinfusion to maintain a theorical filtration fraction between 18-22%. Isovolemic CRRT will be encouraged if volume overload status is not present. After 72 hours, CVVH will be continued and filtration dose (ml/kg/h) will be adjusted to achieve creatinine levels between 80-120 umol/L until patient recovers urine output and / or tolerates intermittent hemodialysis. | Other | CVVH-ST150 |

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Technical CRRT efficiency (time frame: 72 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01790620, which also lists 19 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2019.
