Here is the design of a clinical trial:

Official Title: Effects of Cyclosporine a Pretreatment of Deceased Donor on Kidney Graft Function: a Randomized Controlled Trial

Included conditions:
- Brain Death
- Kidney Transplantation

Study Armgroups:
- {'label': 'control group', 'type': 'PLACEBO_COMPARATOR', 'description': 'control group receives a placebo', 'interventionNames': ['Drug: Placebo']}
- {'label': 'intervention group', 'type': 'EXPERIMENTAL', 'description': 'the intervention group receives 2.5 mg/kg of cyclosporine', 'interventionNames': ['Drug: cyclosporine A']}

Interventions:
- {'type': 'DRUG', 'name': 'cyclosporine A', 'description': 'the intervention group receives 2.5 mg/kg of cyclosporine', 'armGroupLabels': ['intervention group']}
- {'type': 'DRUG', 'name': 'Placebo', 'description': 'control group receives a placebo', 'armGroupLabels': ['control group']}

Primary Outcomes:
- {'measure': 'Percentage of delayed graft function defined by a need of at least one hemodialysis session', 'timeFrame': 'within the 7 days following renal transplantation.'}

Please estimate the sample size based on the assumption: 
80% power, significance level of 0.05 (two-sided alpha), and a 10% dropout rate.
Sample size
          The sample size was determined to obtain 80% power to detect a 10% difference for rate of DGF (as defined in the primary endpoint section) at day 7 between the two groups, as this difference is considered to be clinically significant. In accordance with previous studies [7, 8], we hypothesized that 30% of the patients in the placebo group and 20% of the patients in the intervention group will develop DGF. With the threshold for statistical significance set at a p value of 0.05 (two-sided alpha), these calculations showed that 588 participants (recipients) are needed (294 per group). Assuming that a potential 10% of participants will be lost to follow-up (for the primary or the secondary endpoints), a total of 648 recipients needs to be included. Secondary outcomes will be compared between the two groups: using the chi2 test or Fisherâs exact test for categorical variables and Studentâs t test for continuous variables.
