Treat-to-target Trial of Basal Insulin in Post-transplant Hyperglycemia (TIP): Efficacy and Safety of a Novel Protocol in Renal Transplant Recipients Receiving a Tacrolimus-based Immunosuppression
In Brief
A Phase 2 clinical trial evaluating Insulatard (long-acting insulin) and Conventional for Hyperglycemia. Completed, enrolled 50 participants across 1 site.
Detailed Summary
Treat-to-target trial of basal Insulin in Post-transplant hyperglycemia (TIP): efficacy and safety of a novel protocol in renal transplant recipients receiving a tacrolimus-based immunosuppression DESCRIPTION: A prospective, randomized safety and efficacy study of long-acting insulin (Insulatard®) as therapy against post-transplant hyperglycemia in renal transplant recipients OBJECTIVES: Primary Objective: To demonstrate superiority of long-acting insulin (Insulatard®) against post-transplant hyperglycemia, in comparison to conventional treatment, and as evaluated by HbA1c Secondary Objectives: * To assess the average post-transplant glucose levels in renal transplant patients under conventional blood-glucose lowering therapy during a period of at least 14 days after transplantation by measuring the capillary blood glucose levels four times daily in both groups of patients (fasting, before lunch, before supper, after supper) * To detect the number of post-transplant patients who - without any history of pre-transplant diabetes - develop at least one episode of post-transplant hyperglycemia (\> 140 mg/dl before supper) * To detect the average number of hyperglycemic episodes in post-transplant patients with at least one episode of post-transplant hyperglycemia and without any history of diabetes * To assess the amount of (long-acting) insulin (in IU) needed in order to obtain a target capillary blood glucose level in the range of 110 mg/dl to 120 mg/dl before supper in post-transplant patients with incidence of hyperglycemia * To assess the safety of long-acting insulin in controlling post-transplant hyperglycemia (especially with regards to episodes of hypoglycemia (glucose-level \< 60 mg/dl) * To assess the prevalence of post-transplant diabetes, as diagnosed by an abnormal oral glucose tolerance on days 90, 180 and 360 after transplantation, in the group of patients which has been treated with long-acting insulin, in comparison to patients who received conventional treatment * To assess the morbidity (hospitalization, infections, subsequent episodes of surgery, requirement of non-immunosuppressive, non- blood glucose lowering medication) in the group of patients with long-acting insulin for hyperglycemia, in comparison to patients randomized into the group receiving conventional treatment * To assess the renal outcome (creatinine levels, rejections) in the group of patients which is foreseen to be treated with long-acting insulin for hyperglycemia, in comparison to patients randomized into the group receiving conventional treatment
Study Details
Timeline
Interventions
In group No.1 (study arm 1 (=A)), patients will be treated with long-acting insulin (Insulatard) as soon as the glucose-level before supper surpasses 140 mg/dl. The normoglycemic goal in this group will be from 110 to 120 mg/dl.
In group No.2 (study arm 2 (=B)), patients will be treated conventionally according to the decisions taken by the physicians on the ward. The following suggestions will be brought to the attention of the ward in order to standardize the treatment of the patients in study arm B: 1. Treatment in this group should be initiated if the fasting glucose level surpasses the renal glucose threshold, i.e. 180 mg/dl. 2. As the proposed life-style modifications for the treatment of NODAT1 are not feasible during this very early post-transplant phase, the basis of the conventional therapy will be proposed to be sulfonyl urea drugs (i.e. Gliclazide - Diamicron®, 30 mg, not more than twice daily). 3. Short-acting insulin will be strongly recommended to be used for corrections of capillary blood glucose levels above 250 mg/dl.
