NCT03619564

Brief Summary

The purpose of this study is to determine the effect of a ketoanalogue supplemented very low protein diet on eGFR decline in chronic kidney disease compared to a low protein diet (0.6 g/kg, LPD) or no protein restriction.

Outcome Measures

Primary Outcomes (1)

  • Primary composite endpoint: 50 % eGFR decline or renal replacement therapy [Time Frame: From inclusion to 2 years follow up]

    Primary composite endpoint \[Time Frame: From inclusion/Patient enrolment to 2 years follow up\]. Need for renal replacement therapy or an at least 50% reduction in the estimated glomerular filtration rate (eGFR) compared to time of patient inclusion into the study and after 2 years

    2 years

Secondary Outcomes (2)

  • Prescribed diet

    2 years

  • Impact of compliance to prescribed protein diet on the eGRF decline

    2 years

Study Arms (3)

No protein restriction

No protein restriction

Low protein diet (LPD)

LPD: \< 0.8 g/kg bodyweight

Ketoanalogue suppl. very LPD

Primary nephrologic care

You may qualify if:

  • Age \>=20 years
  • Diagnosis of chronic kidney disease stage 3b to 5 (non-dialysis) according to KDIGO1, i.e. GFR \< 45 ml/min/1.73 m².
  • Regular dietetic consultancy (at least once a year) for patients with stages 4 and 5 (GFR \< 30 ml/min/1.73m²) who are following a LPD or sVLPD.
  • Written informed consent according to local regulations

You may not qualify if:

  • Disturbed amino acid metabolism, e.g. phenylketonuria
  • A kidney transplant
  • Sustained high blood pressure (inadequately controlled (\>160 mmHg systolic or \>110 mmHg diastolic) despite ≥3 antihypertensive medications)
  • Independent life-threatening disease(s), i.e. terminal cancer, AIDS, stage IV heart failure, end stage liver cirrhosis
  • Renal insufficiency caused by
  • Renal cancer
  • Genetic renal diseases, e.g. polycystic kidney disease, congenital nephrotic syndrome
  • Hypersensitivity to the active substances or to any of the excipients of the ketoanalogue supplement
  • Furthermore, pregnant and breast-feeding patients
