Abstract
BACKGROUND The influence of pre- or postprandial administration on pharmacokinetics of cyclosporine is supposed to be less in gel-based formulations than in microemulsions. This study was designed to investigate the influence of a high-fat meal on the pharmacokinetic profile of the two cyclosporine containing formulations Ciclosporin Pro (gel-based emulsion) and Sandimmun®Optoral (microemulsion) in renal transplant recipients. METHODS A randomized, open-label, repeated-measurement, comparative phase IV trial was conducted with two sequence groups for nutrition condition (fasting→fed, fed→fasting) and two treatment phases (Sandimmun® Optoral → Ciclosporin Pro), each covering both nutrition conditions. Primary pharmacokinetic variable of interest was the reduction of bioavailability due to high-fat food compared to fasting conditions measured by the difference D of ln-transformed bioavailability variables (AUCSS, τ, Css, max, und Css, min). RESULTS A nutrition effect was found for both study medications with respect to the parameters AUCSS, τ and CSS, max, but not to CSS, min. The reduction of bioavailability caused by high-fat food was not significantly different for Sandimmun®Optoral and Ciclosporin Pro. CONCLUSIONS An effect of high-fat breakfast prior to the morning dose on AUCSS, τ and CSS, max was found for Sandimmun® Optoral and for Ciclosporin Pro. Trough level monitoring did not capture ingestion-related variability. Conversion to Ciclosporin Pro seems to be safe with regard to intra-individual pharmacokinetic variability.

Abstract
Using positron emission tomography imaging, we determined the hepatic concentrations and hepatobiliary transport of [11 C]rosuvastatin (RSV; i.v. injection) in the absence (n = 6) and presence (n = 4 of 6) of cyclosporin A (CsA; i.v. infusion) following a therapeutic dose of unlabeled RSV (5 mg, p.o.) in healthy human volunteers. The sinusoidal uptake, sinusoidal efflux, and biliary efflux clearance (CL; mL/minute) of [11 C]RSV, estimated through compartment modeling were 1,205.6 ± 384.8, 16.2 ± 11.2, and 5.1 ± 1.8, respectively (n = 6). CsA (blood concentration: 2.77 ± 0.24 μM), an organic-anion-transporting polypeptide, Na+ -taurocholate cotransporting polypeptide, and breast cancer resistance protein inhibitor increased [11 C]RSV systemic blood exposure (45%; P < 0.05), reduced its biliary efflux CL (52%; P < 0.05) and hepatic uptake (25%; P > 0.05) but did not affect its distribution into the kidneys. CsA increased plasma concentrations of coproporphyrin I and III and total bilirubin by 297 ± 69%, 384 ± 102%, and 81 ± 39%, respectively (P < 0.05). These data can be used in the future to verify predictions of hepatic concentrations and hepatobiliary transport of RSV.

Abstract
PURPOSE To evaluate the efficacy and safety of cyclosporine nanoemulsion 0.05% compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%. METHODS This was a multicenter, randomized, evaluator-masked, active control, parallel, phase IV study. A total of 227 patients were randomly allocated to instill cyclosporine nanoemulsion 0.05% (CN) twice daily, cyclosporine emulsion 0.05% (CE) twice daily, or diquafosol sodium 3% (DQ) six times daily. Non-inferiority of CN was analyzed by primary endpoint (cornea and conjunctival staining scores at week 12). The secondary endpoints were scores of corneal staining, conjunctival staining, tear break-up time, Schirmer test, and Ocular Surface Disease Index at weeks 4 and 12. RESULTS Primary endpoints showed statistically significant improvements in all groups. Primary endpoints were -6.60 for the CN group, -5.28 for the CE group, and -6.63 for the DQ group (National Eye Institute scale from 0 to 33), verifying the non-inferiority of CN compared to CE (95% confidence interval, -0.15 to 2.80, Δ>-2.88). In intergroup comparison between CN and CE groups, the CN group had significantly more decreased conjunctival staining score at week 12. Intergroup comparison between CN and DQ groups showed consistent statistically significant improvements in TBUT and Schirmer test in the CN group. In the DQ group, TBUT showed late statistically significant improvement at week 12 and Schirmer test showed relatively short-term statistically significant improvement at week 4. CONCLUSIONS Cyclosporine nanoemulsion 0.05% was equivalently efficient compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%. In addition, CN showed significant improvements in several parameters for treatment of dry eyes.

Abstract
BACKGROUND This study is aim to compare the clinical effectiveness between the two most prominent dry eye disease (DED)-specific eye drops, 0.05% cyclosporine (CN) and 3% diquafosol (DQ). METHODS This is a multi-centered, randomized, masked, prospective clinical study. A total of 153 DED patients were randomly allocated to use CN twice per day or DQ six times daily. Cornea and conjunctival staining scores (NEI scale), tear break-up time (TBUT), Schirmer test scores, and ocular surface disease index (OSDI) score were measured at baseline, 4 and 12 weeks after treatment. RESULTS At 12 weeks after treatment, NEI scaled scores were significantly reduced from the baseline by - 6.60 for CN and - 6.63 for DQ group (all P < 0.0001, P = 0.9739 between groups). TBUT and Schirmer values for CN were significantly improved from the baseline at 4 and 12 weeks (P = 0.0034, P < 0.0001 for TBUT, P = 0.0418, P = 0.0031 for Schirmer test). However, for DQ, TBUT showed significant improvement at 12 weeks only (P = 0.0281). Mean OSDI score differences from the baseline to 12 weeks were improved by - 13.03 ± 19.63 for CN and - 16.11 ± 20.87 for DQ, respectively (all P < 0.0001, P = 0.854 between groups). Regarding drug compliance, the mean instillation frequency of CN was less than that of DQ (P < 0.001). There were no statistically significant intergroup differences in safety evaluation. CONCLUSIONS The level of improvement regarding NEI, TBUT, and OSDI scores were not significantly different between the two treatment groups. However, with regards to the early improvement of TBUT and patient compliance, patients using CN improved faster and with greater adherence to drug usage than did those treated with DQ.

Abstract
Drug-induced gingival overgrowth is a condition caused by side effects of treatment with one of three types of drugs: phenytoin (used in epilepsy treatment), cyclosporine A (used in transplantology after allogenic organ transplants) and calcium channel blockers (used in the treatment of hypertension). Gingival overgrowth leads to inflammation within the gums and periodontium and can amplify the existing periodontal disease leading to tooth loss. Patients who have undergone kidney transplant are given immunosuppressants to prevent transplant rejection and mostly it is accompanied with calcium channel blockers to treat hypertension associated with kidney transplant. This article reports a case of recent gingival enlargement associated with cyclosporine A and amlodipine given to a kidney transplant patient from the past 11 years.

Lee, SH, Park, JB, Oh, CK, Kim, MS, Kim, SJ, Ha, J
Yonsei medical journal. 2017;(1):217-225
Abstract
PURPOSE The increased tolerability of enteric-coated mycophenolate sodium (EC-MPS), compared to mycophenolate mofetil, among kidney transplant recipients has the potential to facilitate cyclosporine (CsA) minimization. Therefore, a prospective trial to determine the optimum EC-MPS dose in CsA-based immunosuppression regimens is necessary. MATERIALS AND METHODS A comparative, parallel, randomized, open-label study was performed for 140 patients from four centers to compare the efficacy and tolerability of low dose CsA with standard dose EC-MPS (the investigational group) versus standard dose CsA with low dose EC-MPS (the control group) for six months in de novo kidney transplant recipients. Graft function, the incidence of efficacy failure [biopsy-confirmed acute rejection (BCAR), death, graft loss, loss to follow-up], and adverse events were compared. RESULTS The mean estimated glomerular filtration rate (eGFR) of the investigational group at six months post-transplantation was non-inferior to that of the control group (confidence interval between 57.3 mL/min/1.73m² and 67.4 mL/min/1.73 m², p<0.001). One graft loss was reported in the control group, and no patient deaths were reported in either group. The incidence of BCAR of the investigational group was 8.7%, compared to 18.8% in the control group (p=0.137), during the study period. There were no significant differences (p>0.05) in the incidence of discontinuations and serious adverse events (SAE) between the groups. CONCLUSION CsA minimization using a standard dose of EC-MPS kept the incidence of acute rejection and additional risks as low as conventional immunosuppression and provided therapeutic equivalence in terms of renal graft function and safety issues.

Abstract
The European Tacrolimus versus Ciclosporin-A Microemulsion (CsA-ME) Renal Transplantation Study demonstrated that tacrolimus decreased acute rejection rates at 6 months. Primary endpoints of this investigator-initiated, observational 7-year follow-up study were acute rejection rates, patient and graft survival rates, and a composite endpoint (BPAR, graft loss, and patient death). We analyzed data from the original intent-to-treat population (n = 557; 286 tacrolimus, 271 CsA-ME). A total of 237 tacrolimus and 208 CsA-ME patients provided data. At 7 years, Kaplan-Meier estimated rates of patients free from BPAR were 77.1% in the tacrolimus arm and 59.9% in the CsA-ME arm, graft survival rates amounted to 82.6% and 80.6%, and patient survival rates to 89.9% and 88.1%. Estimated combined endpoint-free survival rates were 60.2% in the tacrolimus arm and 47.0% in the CsA-ME arm (P = <0.0001). A higher number of patients from the CsA-ME arm crossed over to tacrolimus during 7 year follow-up: 19.7% vs. 7.9% (P = <0.002). More patients in the tacrolimus group stopped steroids and received immunosuppressive monotherapy. Significantly, more CsA-ME patients received lipid-lowering medication and experienced cosmetic and cardiovascular adverse events. Tacrolimus-treated renal transplant recipients had significantly higher combined endpoint-free survival rates mainly driven by lower acute rejection rates despite less immunosuppressive medication at 7 years.

Abstract
AIM: To report a 10-year follow-up of patients suffering from severe dry eye syndrome (DES) initially treated with topical ciclosporin A (tCSA) for 6 months. METHODS The charts of 26 patients with severe DES related to keratoconjunctivitis sicca (KCS) and followed for a minimum 10-year follow-up were retrospectively reviewed. All of them were treated initially with tCSA for 6 months. The Schirmer I test, fluorescein and lissamine green staining scores and tear film break-up time (TBUT) were recorded to assess clinical symptoms before, during and after treatment. The subjective signs were evaluated with the ocular surface disease index (OSDI) questionnaire. Prolongation and reintroduction of tCSA after the initial treatment and combined treatments were also noted. RESULTS Overall the median (IQR) duration of tCSA treatment was 23 (7-51) months after a prolonged induction treatment lasting 20 (8-41) months during the 10-year follow-up. For symptoms, a statistically significant difference in the OSDI between baseline and the end of the 10-year follow-up was not found (p=0.67). We noted a statistically significant improvement in all clinical signs after the initial treatment period, still present at the end of follow-up. Only 6.5% of the patients needed reintroduction of tCSA after their prolonged induction treatment. CONCLUSIONS The improvement observed after an initial tCSA treatment was sustained after a long-term follow-up with few cases requiring additional tCSA treatment. A prolonged induction treatment to decrease initial inflammatory local signs is a promising option in KCS.

Abstract
BACKGROUND Immunosuppression with calcineurin inhibitors remains the mainstay of treatment after kidney transplantation; however, long-term use of these drugs may be associated with nephrotoxicity. In this regard, the current approach is to optimise available immunosuppressive regimens to reduce the calcineurin inhibitor dose while protecting renal function without affecting the efficacy. The ATHENA study is designed to evaluate renal function in two regimens: an everolimus and reduced calcineurin inhibitor-based regimen versus a standard treatment protocol with mycophenolic acid and tacrolimus in de novo kidney transplant recipients. METHOD/DESIGN ATHENA is a 12-month, multicentre, open-label, prospective, randomised, parallel-group study in de novo kidney transplant recipients (aged 18 years or older) receiving renal allografts from deceased or living donors. Eligible patients are randomised (1:1:1) prior to transplantation to one of the following three treatment arms: everolimus (starting dose 1.5 mg/day; C0 3-8 ng/mL) with cyclosporine or everolimus (starting dose 3 mg/day; C0 3-8 ng/mL) with tacrolimus or mycophenolic acid (enteric-coated mycophenolate sodium at 1.44 g/day or mycophenolate mofetil at 2 g/day) with tacrolimus; in combination with corticosteroids. All patients receive induction therapy with basiliximab. The primary objective is to demonstrate non-inferiority of renal function (eGFR by the Nankivell formula) in one of the everolimus arms compared with the standard group at month 12 post transplantation. The key secondary objective is to assess the incidence of treatment failure, defined as biopsy-proven acute rejection, graft loss, or death, among the treatment groups. Other objectives include assessment of the individual components of treatment failure, incidence and severity of viral infections, incidence and duration of delayed graft function, incidence of indication biopsies, slow graft function and wound healing complications, and overall safety and tolerability. Exploratory objectives include evaluation of left ventricular hypertrophy assessed by the left ventricular mass index, evolution of human leukocyte antigen and non-human leukocyte antigen antibodies, and a cytomegalovirus substudy. DISCUSSION As one of the largest European multicentre kidney transplant studies, ATHENA will determine whether a de novo everolimus-based regimen can preserve renal function versus the standard of care. This study further assesses a number of clinical issues which impact long-term outcomes post transplantation; hence, its results will have a major clinical impact.

Abstract
BACKGROUND Choice of calcineurin inhibitor may influence response to antiviral therapy in liver transplant patients with hepatitis C virus (HCV) infection. MATERIAL AND METHODS In a randomized, multicenter, 80-week trial, liver transplant recipients (>6 months and £10 years post-transplant) with recurrent HCV infection received cyclosporine (n=50) or tacrolimus (n=42) with a 48-week course of pegylated interferon (peg-IFNα2a) and ribavirin. Twenty-three patients in each group completed the trial on study medication. The primary endpoint was sustained virological response (SVR) 24 weeks after the end of antiviral therapy, for which 43 patients were eligible for analysis. RESULTS The rate of SVR was 60.0% (12/20) with cyclosporine and 43.5% (10/23) with tacrolimus (adjusted odds ratio 1.85; 95% CI 0.53-6.43; p=0.331). There were no significant intergroup differences for rapid or early virological response, relapse, HCV RNA viral load, or fibrosis progression. One cyclosporine-treated patient experienced acute rejection. One patient died in each group. Adverse events, treatment-related adverse events, and serious adverse events were similar between groups. CONCLUSIONS Since fewer patients were recruited than planned (92 versus 355), the study was underpowered and robust conclusions cannot be drawn regarding the effect of cyclosporine and tacrolimus on virological responses to antiviral treatment for recurrent HCV after liver transplantation. However, as reported in other trials, SVR was higher in cyclosporine-treated patients.
