This study will be started in subjects with eGFR >30 mL/min*1.73m2. Other important inclusion criteria are: confirmed diagnosis of ADPKD, body mass index of <35 kg/m2, in good health determined by: medical history, physical examination, ECG, serum/urine biochemistry, hematology tests. See protocol page 29.
Following determination of the effects in patients with eGFR >30 mL/min*1.73m2, subjects with eGFR <30 mL/min*1.73m2 will be entered as appropriate. If necessary, subjects withdrawn from the trial will be replaced.
- Subjects with previous exposure to tolvaptan
- Subjects with recent (within last 6 months) renal surgery
- Subjects with evidence of renal cystic disease other than ADPKD (e.g. renal cancer)
- Safety contraindications including: reproductive precautions, unawareness of thirst, severe allergic reactions to compounds with similar chemical structure as tolvaptan, significant risk factors for renal impairment other than ADPKD (e.g. advanced diabetes), a history of significant coagulation defects, critical electrolyte inbalances, low blood volume, clinically significant anemia, history of substance abuse, uncontrolled hypertension.
- Contraindications to or interference with MRI assessments
See protocol page 30 for further details.
