Tolvaptan use in ADPKD – ERBP Recommendations

In a recent NDT paper, the ERA-EDTA Working Groups of Inherited Kidney Disorders and European Renal Best Practice provides guidance for making the decision as to which ADPKD patients to treat with tolvaptan, and presents a hierarchical decision algorithm according to risk-factor assessments in a descending order of reliability.

The key recommendations on tolvaptan use the group makes are:

  • We suggest that tolvaptan can be prescribed to adult ADPKD patients aged <50 years with CKD stages 1–3a (eGFR >45 mL/min/1.73 m2) who have demonstrated or who are likely to have rapidly progressing disease.  CKD stage must be interpreted in conjunction with age.
  • We recommend not starting tolvaptan in patients aged 30–40 years with CKD stage 1.
  • We recommend not starting tolvaptan in patients aged 40–50 years with CKD stages 1 or 2 (eGFR >60 mL/min/1.732).

How to define rapid progression:

  • A confirmed annual eGFR decline ≥5 mL/min/1.73 m2 in 1 year, and/or ≥2.5 mL/min/1.73 m2 per year over a period of 5 years
  • A TKV increase of >5% per year by repeated measurements (preferably three or more, each at least 6 months apart and by MRI).

Dosing guidelines:

  • Start tolvaptan treatment with a dose of 45 mg in the morning and 15 mg in the evening.
  • Uptitrate the dose of tolvaptan to 60/30 and 90/30 mg when tolerated.
  • Tolvaptan should be discontinued when patients approach ESRD.

    There is no contradiction – recommendation 1 reinforces that the disease should be progressive whereas and 2, and 3 point out where it is recommended to hold on.
