LOW CYCLO: Study Evaluating the Benefit of Two Doses of Ciclosporine in de Novo Cardiac Transplant

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified April 2007 by Hospices Civils de Lyon.
Recruitment status was:  Active, not recruiting

Hospices Civils de Lyon Identifier:
First received: September 8, 2005
Last updated: April 26, 2007
Last verified: April 2007

Primary Objective:

  • Evaluation of the benefit on renal function of one year of a low dose of ciclosporine versus the usual dose

Secondary Objective:

  • To evaluate the immunosuppressive efficacy and tolerance of the treatment

Study Duration:

Twelve months for each patient

Study Treatment: Ciclosporine

Group A: low dose >= 130 µg/l < T0 ciclosporinemia < 200 µg/l; Group B: standard dose >= 200 µg/l < T0 ciclosporinemia < 300 µg/l.

Study Visits:

One visit every 15 days, for the first three months; then 1 visit every month, for 6 months; and 1 visit at 9 and 12 months.

Associated Treatments:

  • Mycophenolate (Cellcept®), 3g a day
  • Corticoids, as used for transplanted patients

Randomization: Randomization will occur when it is decided that ciclosporine will be introduced.

Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: LOW CYCLO: A Multicenter, Prospective, Randomized Study Evaluating the Benefit, on Renal Function, of Two Doses of Ciclosporine: Low Dose Versus Usual Dose, in Association With Mycophenolate and Corticoïds, in de Novo Cardiac Transplant

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Evolution of renal function, as assessed by the evolution between the two treatment groups at 12 months versus baseline serum creatinine level

Secondary Outcome Measures:
  • Area under curve of creatinine at 12 months
  • Cystatin C level at 1, 2, 3, 6 and 12 months
  • Creatinine clearance at 6 and 12 months
  • Proteinuria and microalbuminuria at 6 and 12 months
  • Secondary outcomes include those linked to the immunosuppressive efficacy and tolerance of the treatment: Difference in appearance incidence of acute graft reject and adverse events
  • Myocardial biopsy (International Society of Heart and Lung Transplantation [ISHLT] grades)
  • Difference in the evolution of left ventricular function and cardiovascular risk factors between the two groups at 6 and 12 months versus baseline: left ventricular ejection fraction and shortening fraction (echocardiogram)
  • systolic and diastolic blood pressure
  • fasting glycemia, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides
