About this study

Official title: RandomizEd ClinicAL triaL on the Efficacy and saFety of Incremental Hemodialysis

Background: The thrice-weekly hemodialysis (HD) regimen is widely accepted as a standard prescription. The concept of incremental dialysis has been established as a possible alternative for patients with preserved diuresis and end-stage renal failure in need of HD. The main problems related to prescription of incremental HD are an arbitrary use of infrequent regimens and the lack of clear standards for incorporating residual kidney function (RKF) in the assessment of HD dose. Several models have been proposed for prescription of incremental dialysis. The latest, the variable target model (VTM), gives more clinical weight to the RKF and allows less frequent HD treatments at lower RKF. Despite increasing evidence derived from observational studies to support the use of incremental HD, RCTs are lacking and, therefore, urgently needed.

The Department of Nephrology, Dialysis and Transplantation of the Azienda Ospedaliero Universitaria Consorziale Policlinico, Bari, Italy and the EUDIAL Working Group of the European Renal Association - European Dialysis Transplant Association (ERA-EDTA) are starting a randomized clinical trial (RCT) in incident HD patients, whose name is "REAL LIFE", by using the acronym of its whole definition: RandomizEd clinicAL triaL on the effIcacy and saFety of incremental haEmodialysis. REAL LIFE is a pragmatic, prospective, multicentre, open label RCT, investigator-initiated, comparing the intervention arm (incremental HD) with the control arm (standard 3HD/wk). The trial, originally conceived by experts at the Division of Nephrology of the Miulli General Hospital, Acquaviva delle Fonti, Italy, consists in starting the HD treatment adopting the new incremental approach guided by the VTM. The primary outcome is the survival of kidney function, with the event defined as urinary output (UO) ≤ 200 mL/day, confirmed by a further collection after 2 weeks to exclude temporary illness.

Discussion: REAL LIFE will enable the investigators to know with the highest level of scientific evidence the safety and efficacy of an incremental approach to the start of HD treatment.

Read the detailed description

The majority of dialysis patients starting hemodialysis (HD) are currently treated with a fixed dose thrice-weekly HD (3HD/wk). The 3HD/wk regimen has been assumed, until recently, almost as a dogma in the dialysis community. Incremental HD is based on the simple idea of adjusting its dose according to the metrics of RKF. REAL LIFE is a pragmatic, prospective, multicentre, open label RCT, investigator-initiated, comparing the intervention arm (incremental HD) with the control arm (standard 3HD/wk). A Variable Target Model (VTM) has been suggested, which gives more clinical weight to the RKF and allows less frequent HD treatments in patients with lower RKF. The investigators recommend to start and keep on with once-weekly HD, which should be possible until residual renal urea clearance (KRU) falls below 2.5 - 3.0 mL/min/35 L, i.e., glomerular filtration rate (GFR) ≈ 4 mL/min/1.73 m2.

The primary outcome is the survival of kidney function, with the event defined as urinary output (UO) ≤ 200 mL/day, confirmed by a further collection after 2 weeks to exclude temporary illness. Secondary outcomes are: composite primary cardiovascular endpoint (cardiovascular death, non fatal myocardial infarction and/or or non fatal stroke); intima-media thickness of the carotid arteries; specific cardiomyopathy control; RKF preservation; patients survival; hospital admissions; anemia control; mineral and bone disorder control, and middle molecules removal.

The sample size calculation is based on the primary outcome "presence of anuria". The assumptions for calculating the sample size, derived from data of Teruel Briones et al., are the following:

  • Percentage of subjects who developed anuria in the experimental group (incremental HD): 25%
  • Percentage of subjects who developed anuria in the control group (standard 3HD/wk): 51%
  • Power: 0.8
  • Ratio: 1:1
  • Non-compliance: 20%
  • Total expected sample size: 190 (95 participants in each group)

The assessment of the key kinetic parameters as well as the guide to the selection of operative parameters, as required to get the required equilibrated Kt/V (eKt/V = 1.05), will be done by using SPEEDY, a spreadsheet prescription tool that uses essentially the same equations used by Solute Solver, the software based on the double pool UKM recommended by the 2015 KDOQI guidelines. SPEEDY is freely available at the European Nephrology Portal (ENP).

The link is https://enp-era-edta.org/174/page/home. The control arm includes patients put on a thrice-weekly HD schedule, as detailed above. The dialysis dose (eKt/V) should be about 1.05.

PICO question:

Participants with CKD-EPI GFR ≤ 10 ml/min and daily urine output > 600 ml Intervention: one or two weekly hemodialysis (as detailed above) Comparator: three weekly hemodialysis (as per standard practice and as detailed above) Outcome: Residual renal function

Being tested
Incremental hemodialysis, Conventional hemodialysis

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Incremental hemodialysisProcedure or surgery

    95 patients will start renal replacement therapy (RRT) with an incremental hemodialysis (once-weekly or twice-weekly) regimen.

  • Conventional hemodialysisProcedure or surgery

    95 patients will start renal replacement therapy (RRT) with the standard (thrice-weekly) hemodialysis regimen.

Study groups in NCT04360694
Study groupRoleWhat they receive
Incremental hemodialysisExperimentalProcedure: Incremental hemodialysis. It consists in reducing the frequency or number of sessions per week with which patients start the HD treatment. The experimental group will start with one session/week, then the number of weekly sessions will be increased to two and later to three as per criteria for progression
Receives: Procedure: Incremental hemodialysis
Conventional hemodialysisActive comparatorProcedure: Conventional hemodialysis. It is controlled through usual clinical practice, based on starting the HD treatment with three sessions per week (control group).
Receives: Procedure: Conventional hemodialysis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants whose kidney function remains >200 ml

    The survival of kidney function is defined as a time to the event (anuria): the anuria is defined as urinary output (UO) ≤ 200 mL/day, confirmed by a further collection after 2 weeks to exclude temporary illness

    Measured: 24 months

Secondary outcomes (10)
  1. Number of participants who develop cardiovascular death, non fatal myocardial infarction and/or or non fatal stroke (composite outcome)

    Cardiovascular death, non fatal myocardial infarction and/or or non fatal stroke

    Measured: 24 months

  2. Mean value of intima-media thickness of the carotid arteries of participants at end of treatment and change from beginning to end of treatment

    Echographic evaluation of intima-media thickness of the carotid arteries

    Measured: 12 and 24 months

  3. Value of left ventricular ejection fraction established with cardiac ultrasound at end of treatment and change from beginning to end of treatment

  4. Value of residual kidney function (RKF) preservation established by the slope of decline of residual renal urea clearance

    The rate of decline in RKF defined as the slope of decline of residual renal urea clearance

    Measured: 24 months

  5. Number of people who die

    The follow-up time will be determined in days. It will be defined as the difference in days from the date of the end of the follow-up minus the date of the baseline visit. Events will be counted either as deaths (follow-up of less than 24 months) or as end of the follow-up

    Measured: 24 months

  6. Number of people who are hospitalized

    The number of admissions will be registered.

    Measured: 24 months

  7. Value of hemoglobin in participants at end of treatment and change from beginning to end of treatment

    Measured: Every month

  8. Value of serum phosphorus, calcium and parathyroid hormone in participants at end of treatment and change from beginning to end of treatment

    Serum phosphorus and calcium levels (in mg/dl), and intact PTH (in pg/dl) will be measured.

    Measured: Every month and three months

  9. Value of serum beta 2 microglobulin (middle molecule) at end of treatment and change from beginning to end of treatment

    The rate of change in serum beta 2 microglobulin in time will be evaluated
