Protocol summary
Study aim
Investigation of the efficacy and safety of Suprotac® compared with Prograf® in liver transplant patients in Iran
Design
Randomized Clinical Trial; Two arms in parallel; Open-label; Phase 4 with 196 patients
Settings and conduct
Eligible patients are randomized into two groups of Suprotac® or Prograf®. Tacrolimus in both groups is administered at a dose of 0.1–0.15 mg/kg orally on the first day post-transplant. Then, dose will be adjusted if needed to reach the desired trough level.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Patients aged between 18 to 70
Exclusion criteria: Receiving any investigational products within the last 30 days; contraindication for tacrolimus; Glomerular Filtration Rate greater than 30
Intervention groups
Group 1: Suprotac® (Nanoalvand)
Group 2: Prograf® (Astellas)
Tacrolimus in both groups is administered at a dose of 0.1–0.15 mg/kg orally on the first day post-transplant. Then, dose will be adjusted if needed to reach the desired trough level. Treatment is continued for one year.
Main outcome variables
Percentage of rejection-free patients between two groups (until one year after transplantation); Comparing the percentage of patient survival, graft survival, and mean trough concentration/dose of tacrolimus between two groups; Adverse events
General information
Reason for update
In the Exclusion Criteria section, the item “Patients who, at the time of entering the study (the end of the second month after transplantation), have a glomerular filtration rate index greater than 30” was changed, given the course of the study, to the phrase “Patients who, at the time of entering the study, have a glomerular filtration rate index greater than 30.”

Randomization (investigator's opinion)
Randomized
Randomization description
Eligible patients will be assigned to treatment using stratified block randomization with blocks of size 2 or 4. Randomization will be stratified according to living or deceased donors. The patients will be carried out using R-CRAN software version 3.6.3. Blocks will be made using permuted block randomization for a total of 196 patients (1:1 allocation ratio). The random series Excel will be placed in the patient recruitment center and a person will be responsible for assigning a random code by the investigator. This code will be assigned in order of entry and based on the stratification in which the patient's donor is living or deceased.
