Pharmacodynamics, Efficacy and Safety of Basiliximab 40 or 80 mg in Combination With Ciclosporine Microemulsion or Everolimus, in Adult Low Risk de Novo Renal Transplant Recipients (IDEALE Study)

Phase 2
Completed
Conditions
Renal Transplantation
Interventions
Drug: Certican®
Drug: Corticosteroids
Registration Number
NCT01596062
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

The aims of this study are to extensively study the levels of CD25-Receptors saturation and expression obtained with 2 different doses of Simulect® in combination with Neoral® (i.e to demonstrate that saturation and expression vary according to the dose of Simulect® given), and to study the levels of CD25-Receptors saturation without Neoral® and compare them to the data with Neoral®.

It will be conducted in low risk de novo adult renal transplant recipients until 12 weeks post-transplant, receiving either a cumulative dose of 40 or 80 mg of Simulect® in combination with Neoral®, or a cumulative dose of 80 mg of Simulect® in a calcineurin inhibitor free immunosuppressant therapy.

Primary Outcome Measures
NameTimeMethod
Saturation Rate of CD25 Antigen Saturation by BasiliximabDay 0, Day 1, Day 4, Day 6, Day 14, Day 21, Day 28, Day 42, Day 56 and Day 84 (Week 12) post-transplantation

CD25 saturation is the percentage of T cells expressing CD25

Area Under the Curve (AUC) of CD25 Saturation by Basiliximab From Day 0 to Day 84Day 84 (Week 12) after transplantation

CD25 saturation is the percentage of T cells expressing CD25. Mean AUC of CD25 was calculated only for patients who received two Simulect® injections.

Secondary Outcome Measures
NameTimeMethod
AUC of Basiliximab Binding to CD25 Receptors From Day 0 to Day 84Day 84 (Week 12) post-transplantation

Mean AUC was calculated only for patients who received two Simulect injections.

Percentage of T-cells That Bind Basiliximab to CD25 ReceptorsDay 0, Day 1, Day 4, Day 6, Day 14, Day 21, Day 28, Day 42, Day 56 and Day 84 (Week 12) post-transplantation

This is the percentage of T cells binding basiliximab at all timepoints.

Percentage of Participants With of Treatment FailuresDay 84 (Week 12), Week 24

Treatment failure was defined either as a BPAR, a graft loss, a death or a loss to follow-up. An extended treatment failure was also defined including treated borderline lesions, BPAR, graft loss, death or loss to follow-up. Treated borderline lesions were considered as acute rejection by investigators and DMC experts.

Estimated Glomerular Filtration Rate (eGFR) at Day 8 and Week 24Day 8, Week 24

(MDRDa formula) with imputation by last observation carried forward (LOCF)

Percentage of Participants With of Biopsy Proven Acute Rejection (BPAR)Day 84 (Week 12), Week 24 post-transplantation

BPAR is one of the components of treatment failure. One assessment of efficacy was BPAR. Renal graft biopsies were performed and the renal tissue was examined to determine if there was acute rejection of the renal transplant.

Percentage of Participants With Biopsy Proven Acute Rejection (BPAR) According to Type and SeverityDay 84 (Week 12), Week 24 post-transplantation

Antibody mediated acute rejection: C4d deposition, presence of circulating antidonor antibody, morphologic evidence of acute tissue injury such as acute tubular necrosis-like minimal inflammation or capillary and/or glomerular inflammation and/or thromboses or arterial inflammation. Cellular acute rejection: acute T-cell mediated rejection Type IA: Significant interstitial infiltration (\> 25% of parenchyma) and foci of moderate tubulitis (\> 4 mononuclear cells/tubular cross section or group of 10 tubular cells) Type IB: Significant interstitial infiltration (\> 25% of parenchyma) and foci of severe tubulitis (\> 10 mononuclear cells/tubular cross section or group of 10 tubular cells) Type IIA: Mild to moderate intimal arteritis. Type IIB: Severe intimal arteritis comprising \> 25% of the lumenal area. Type III: Transmural (full vessel wall thickness) arteritis and/or arterial fibrinoid change and necrosis of medial smooth muscle cells (with accompanying lymphocytic inflammation).
