Summary

International multicenter open-label single-arm confidence-interval-estimation based Phase II clinical trial, aiming to estimate a plausible range of the proportion of patients experiencing efficacy failure in the population, to provide evidence for efficacy and safety of the induction regimen with rATG and infliximab and a go/no go rule for further clinical development.

Detailed description

A total of 75 patients will receive the proposed induction regimen, with expected 68 completers accounting for drop-outs and non-compliances with the protocol. If up to 27 out of the 68 completers experience efficacy failure, a progression into a larger trial will be considered justifiable. If the number of patients experiencing efficacy failure is between 28 and 34 out of 68, the merits of a larger non-inferiority design will be considered depending on the risk/benefit assessment. If more than 34 out of the 68 completers experience efficacy failure, a progression into a larger trial would be considered unjustifiable. 1st kidney transplant recipients (low risk: PRA/cPRA \< 20%, no DSA) will receive short rATG induction (2x1.5 mg/kg) given perioperatively and on first postoperative day. All patients will receive one shot Infliximab mAb at day 2. Since POD1, maintenance IS consists of Tac and tapered steroids therapy. All patients will be followed up for one year. At the POD 0 the first rATG dose (1.5mg/kg) will be given according to the local practice and Methyprednisolon 500mg will be given before reperfusion. At the POD 1 patients will receive methylprednisolon 500mg i.v. followed by second rATG dose (1.5mg/kg). Infliximab 5mg/kg b.w. will be given in slow infusion on POD2. Tacrolimus will be given the first dose before surgery at dose 0.1 mg/kg and next from POD1 at 0.2mg/kg/day and doses adjusted according to blood trough levels (10-15 ng/mL, POD1-POD13, 5-8ng/mL POD 14-90, 4-6ng/mL POD \>90. Prednison (or appropriate dose of methylprednisolone) will be initiated POD 2 at a dose of 20mg/day and slowly tapered down to 5 mg at the POD 7 (POD2: 20mg, POD3: 15mg, POD4-5: 10mg, POD6-7: 7,5mg, \> POD7: 5mg).
