This placebo-controlled, randomized and double-blinded pilot study aims to confirm the previous study performed by Stuard et al. (2010) by proving clinically efficacy and local tolerability of topically applied heparin (Heparin 2,400 IU /ml Cutaneous Spray) in comparison to placebo on suitability of newly constructed primary arteriovenous fistulas in haemodialysed patients AVF at 7 weeks (±1 week) after first study drug administration.

| Main Objective: The primary aims of the study are to evaluate the effect of topically applied heparin in comparison to placebo on suitability of newly constructed primary arteriovenous fistulas in patients planned for haemodialysis at 7th week (± 1 week) after first study drug administration.;Secondary Objective: • The suitability of the AVF (dialysis with a blood flow rate = 350mL/min) at 12th and 24th week after first study drug administration • The functional (unassisted) patency of AVF at 7th, 12th and 24th weeks after first study drug administration. • Time to puncture of mature of fistula first time after AVF creation • Flow volume in the AVF by time (ml/min) assessed by ultrasound at 7th week (± 1 week) after first study drug administration. • Time to first intervention (thrombectomy) • Time from AVF creation to abandonment of access (time to failure) • Adequacy of Dialysis: Fistula is considered as adequate for dialysis if it was cannulatedsuccessfully within 6 month post creation with 2 needles over a period of at least 1 month. • Local safety and tolerability profile of IMP by patients and investigator (Global assessment of tolerability). ;Primary end point(s): The suitability of the AVF (dialysis with a blood flow rate = 300 ml/min ) at 7th week (± 1 week) after first study drug administration;Timepoint(s) of evaluation of this end point: week 7 | — |
