Abstract
Background:Sjogren’s syndrome (SS) is an autoimmune disease affecting excretory glands and characterised by B-cell hyperactivity. Ianalumab (VAY736) is a human monoclonal antibody to B-cell activating factor receptor, engineered for direct ADCC-mediated B-cell depletion. A Phase 2b study evaluated the dose-response of VAY736 vs placebo (PBO) in EULAR SS Disease Activity Index (ESSDAI) change from baseline (CHB) and other secondary endpoints.Objectives:Primary results at Week (Wk) 24 were reported previously1. Here we report 52 Wk safety and efficacy from extended blinded treatment period 2 (TP2).Methods:190 patients (pts) were randomised equally to receive s.c. doses of VAY736 (5, 50, 300 mg) or PBO every 4 Wks (q4w). Eligible pts fulfilled American European Consensus Group (AECG) criteria, were anti-Ro/SSA+, had ESSDAI ≥6 and EULAR SS Patient Reported Index (ESSPRI) ≥5. At Wk 24, after completion of the first blinded TP (TP1), PBO-treated pts were switched to VAY736 150 mg, and pts on 300 mg were re-randomised to continue 300 mg or PBO for 28 Wks in TP2. Pts were followed post-treatment for ≥20 Wks. Safety was assessed for all periods. Due to lack of PBO-control in TP2, descriptive efficacy analysis was performed for ESSDAI, ESSPRI, Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F), Physician’s (PhGA) and Patient’s Global Assessments (PaGA), SF-36, and SS symptom diary (SSSD).Results:Overall, there was no dose dependency of treatment emergent adverse events (TEAEs) except for injection site reactions, which were mostly mild to moderate in severity. Lymphopenia and neutropenia were mostly grade (G)1 and G2, no G4. Most common TEAEs were infections and infestations in exposure-adjusted analysis of incidence rates. Nasopharyngitis and upper respiratory tract infections were the most common TEAEs, with no dose response (Table 1). Tracheobronchitis and pneumonia, were mild to moderate severity, not associated with absolute neutrophil count G3, and none led to treatment withdrawal.At Wk 52, efficacy was sustained for pts who continued 300 mg in TP2 (ESSDAI, ESSPRI, PaGA, PhGA CHB: –9.06, –1.91, –22.03, –35.80, respectively). Efficacy was partially lost for pts switched to PBO at Wk 24 (Figure 1). Improvement was noted for PBO pts switched to 150 mg. Stimulated whole salivary flow at Wk 24 was improved for 300 mg (PBO-adjusted CHB 0.20 ml/min; P=0·037); last measurement at Wk 48 was 0.45 and 0.22 ml/min CHB in pts who continued 300 mg or PBO in TP2, respectively.Conclusion:Ianalumab 300 mg was well tolerated up to 52 Wks. Exploratory efficacy showed that continuous dosing of 300 mg s.c. q4w provided sustained clinical benefit. PaGA was the outcome that showed the most prominent change following switch to PBO or VAY736.References:[1]Dörner T, et al. [OP0302].

Abstract
Background:Primary Sjogren’s syndrome (pSS) is a multi-organ autoimmune disease mainly affecting excretory glands and characterised by B-cell hyperactivity. No approved systemic treatment is available. Ianalumab (VAY736) is an anti-B-cell activating factor (BAFF) receptor fully human monoclonal antibody, engineered for direct ADCC-mediated B-cell depletion.Objectives:This phase 2b study aimed at establishing a dose-response relationship over a range of VAY736 doses, using change from baseline (BL) in EULAR Sjogren’s Syndrome Disease Activity index (ESSDAI) over 24 Weeks (Wks) as primary endpoint. The study is ongoing with a second blinded treatment period up to Wk52. Here we report efficacy and safety Wk24.Methods:190 patients (pts) were randomised 1:1:1:1 to receive monthly s.c. doses of VAY736 (5, 50, 300mg) or placebo (PBO). Prior to 1st-dose of study treatment, pts received methylprednisolone i.v. 250mg. Eligible pts fulfilled American European Consensus Group (AECG) criteria, were anti-Ro/SSA+, had ESSDAI ≥6 and EULAR Sjogren’s Syndrome Patient Reported Index (ESSPRI) ≥5. Statistical methods included MCP-Mod to assess dose-response on change of ESSDAI from BL and responder rate analysis to calculate the proportion of pts with ≥3 points improvement on ESSDAI. Secondary endpoints included ESSPRI, Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F), Physician’s (PhGA) and Patient’s Global Assessments (PaGA), SF-36, stimulated salivary flow (sSF), Schirmer’s test.Results:Primary endpoint was met with statistically significant dose-response for ESSDAI (Figure). The largest ESSDAI reduction was 1.92 points over PBO for VAY736 300mg at Wk24. Responder rate analysis on ESSDAI revealed for 300mg vs PBO responder rates of 42/47 (89.4%) vs 30/49 (61.2%), a difference of 28.1% (p=0.0019). No differences were seen for 5mg and 50mg vs PBO. PhGA change from BL was significantly different between 300mg and PBO (p=0.022). A numerical trend for sSF improvement for VAY736 300mg compared to PBO was notable at Wk24 (p=0.092). For secondary endpoints ESSPRI and FACIT-F, VAY736 treatment showed no benefits over PBO. PBO responses were generally high. Incidence of treatment emergent AEs was comparable across all studied groups, whereby site injection reactions were most frequent, mostly mild and showed a dose-response.Conclusion:Primary endpoint assessing ESSDAI was met, showing statistically significant dose-response for ianalumab with clinically important improvement for 300mg vs PBO. Preliminary safety profile of ianalumab was good.Figure.ESSDAI Change from Baseline over Time up to Week 24 Reveals a Statistically Significant Dose Response RelationshipDisclosure of Interests:Thomas Dörner Grant/research support from: Janssen, Novartis, Roche, UCB, Consultant of: Abbvie, Celgene, Eli Lilly, Roche, Janssen, EMD, Speakers bureau: Eli Lilly, Roche, Samsung, Janssen, Simon J.

Estimating the contribution of everolimus to immunosuppressive efficacy when combined with tacrolimus in liver transplantation: a model-based approach. Clin Pharmacol Ther 2015; 97:411-8.

Abstract
Determining the efficacy contribution of an investigational drug as part of a novel combination regimen that also includes a previously untested dose of a standard treatment is challenging, particularly when "placebo control" data (combination regimen minus the investigational drug) is not available for comparison. This situation was encountered in a phase III trial that tested the combination of the investigational drug everolimus with a dose of tacrolimus lower than used in standard liver transplantation therapy. The challenge was addressed by predicting the efficacy of the placebo control from the study data using a pharmacometric-based exposure-response analysis, selected to account for features specific to the transplant setting: systematic change in drug exposure over time and sparse pharmacokinetic sampling. The efficacy contribution of everolimus was then demonstrated by comparing this prediction to the efficacy of the combination regimen. This pharmacometrics-based approach may contribute to characterization of therapeutic agents in real-world settings.

Abstract
Everolimus (EVR) is a semi-synthetic mammalian target of rapamycin inhibitor currently under development for liver transplantation (LTx) in combination with reduced exposure tacrolimus (rTAC). The relative potency of EVR was assessed in order to generate evidence for concomitant EVR+rTAC exposure in LTx recipients (LTxR). Twelve month data from study H2304 (NCT00622869), a 24-month, randomized, multicenter study in 719 de novo LTxR comparing EVR+rTAC to standard TAC demonstrated superior renal function and comparable efficacy, including fewer and less severe biopsy proven acute rejections with EVR+rTAC. Relative potency (p) of EVR was defined as factor by which the effect of 1 ng/mL of EVR must be multiplied to get comparable immunosuppression as with TAC: p = (TACcon - TACred)/EVRred. Relative efficacy of EVR in 4 different subpopulatlons was consistently 0.64, 0.60, 0.69, and 0.62, respectively. This assessment determined the relative potency of EVR as 0.64 compared to TAC in LTx indicating that EVR and TAC are not equipotent per ng/mL exposure. Knowledge about relative potency will help to rationalize co-exposure of EVR and TAC.

Abstract
BACKGROUND Surgeons have only limited options from case-specific contacts to generate a comprehensive picture about family medicine as a discipline and the family practitioner with its specific issues and characteristics. Thus, the typical function of the family practitioner is often not sufficiently taken into account while aiming for a better cooperation: the primary care of "unselected reasons for encounter" with integration of bio-psycho-social aspects, long-term care, close distance contacts and low-threshold access. In addition, family practitioners and surgeons have different expectations regarding their cooperation, which are important to know and handle. METHODS A selective literature search was undertaken on the self-conception and professional functioning of family medicine as well as on mutual expectations to improve cooperation at the outpatient-inpatient interface. RESULTS/CONCLUSION Surgeons benefit from the knowledge on self-conception and functioning of family practitioners by using options and potentials for the reduction of problems at the outpatient-inpatient interface and for an optimised network.

Abstract
BACKGROUND Surgical diseases are often primarily seen and initially treated as well as further patient care is organised in clinical practice by a general practitioner (GP). During postoperative time periods, GPs do have to i) ensure the surgical treatment success, ii) support reintegration of surgically pretreated patients within their daily and professional life as well as iii) coordinate follow-up care. Therefore, it is indicated for residents in general practice/family medicine to spend a certain time period of approximately 6 months at a surgical department of an outpatient clinic and/or hospital. METHODS A selective literature search was undertaken on the required surgical knowledge, abilities, skills and expertise that need to be achieved by residents of general practice/family medicine or, respectively, future GPs and that are listed within national regulations on further education, recommendations of professional groups as well as documents and data for preparation of exams. RESULTS AND CONCLUSIONS Surgical contents during residency in general practice/family medicine comprise far more than "small surgery" only. Requirements of regulations on specialised medical training for a temporary surgical mentor/supervisor and "trainees" provide orientation for the development of an "ideal" surgical rotation for future GPs.

Renal function at two years in liver transplant patients receiving everolimus: results of a randomized, multicenter study. Am J Transplant 2013; 13:1734-45. [PMID: 23714399 DOI: 10.1111/ajt.12280] [Citation(s) in RCA: 128] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2012] [Revised: 02/06/2013] [Accepted: 02/11/2013] [Indexed: 01/25/2023]
Abstract
In a 24-month prospective, randomized, multicenter, open-label study, de novo liver transplant patients were randomized at 30 days to everolimus (EVR) + Reduced tacrolimus (TAC; n = 245), TAC Control (n = 243) or TAC Elimination (n = 231). Randomization to TAC Elimination was stopped prematurely due to a significantly higher rate of treated biopsy-proven acute rejection (tBPAR). The incidence of the primary efficacy endpoint, composite efficacy failure rate of tBPAR, graft loss or death postrandomization was similar with EVR + Reduced TAC (10.3%) or TAC Control (12.5%) at month 24 (difference -2.2%, 97.5% confidence interval [CI] -8.8%, 4.4%). BPAR was less frequent in the EVR + Reduced TAC group (6.1% vs. 13.3% in TAC Control, p = 0.010). Adjusted change in estimated glomerular filtration rate (eGFR) from randomization to month 24 was superior with EVR + Reduced TAC versus TAC Control: difference 6.7 mL/min/1.73 m(2) (97.5% CI 1.9, 11.4 mL/min/1.73 m(2), p = 0.002). Among patients who remained on treatment, mean (SD) eGFR at month 24 was 77.6 (26.5) mL/min/1.73 m(2) in the EVR + Reduced TAC group and 66.1 (19.3) mL/min/1.73 m(2) in the TAC Control group (p < 0.001). Study medication was discontinued due to adverse events in 28.6% of EVR + Reduced TAC and 18.2% of TAC Control patients. Early introduction of everolimus with reduced-exposure tacrolimus at 1 month after liver transplantation provided a significant and clinically relevant benefit for renal function at 2 years posttransplant.

Abstract
In a prospective, multicenter, open-label study, de novo liver transplant patients were randomized at day 30±5 to (i) everolimus initiation with tacrolimus elimination (TAC Elimination) (ii) everolimus initiation with reduced-exposure tacrolimus (EVR+Reduced TAC) or (iii) standard-exposure tacrolimus (TAC Control). Randomization to TAC Elimination was terminated prematurely due to a higher rate of treated biopsy-proven acute rejection (tBPAR). EVR+Reduced TAC was noninferior to TAC Control for the primary efficacy endpoint (tBPAR, graft loss or death at 12 months posttransplantation): 6.7% versus 9.7% (-3.0%; 95% CI -8.7, 2.6%; p<0.001 for noninferiority [12% margin]). tBPAR occurred in 2.9% of EVR+Reduced TAC patients versus 7.0% of TAC Controls (p = 0.035). The change in adjusted estimated GFR from randomization to month 12 was superior with EVR+Reduced TAC versus TAC Control (difference 8.50 mL/min/1.73 m(2) , 97.5% CI 3.74, 13.27 mL/min/1.73 m(2) , p<0.001 for superiority). Drug discontinuation for adverse events occurred in 25.7% of EVR+Reduced TAC and 14.1% of TAC Controls (relative risk 1.82, 95% CI 1.25, 2.66). Relative risk of serious infections between the EVR+Reduced TAC group versus TAC Controls was 1.76 (95% CI 1.03, 3.00). Everolimus facilitates early tacrolimus minimization with comparable efficacy and superior renal function, compared to a standard tacrolimus exposure regimen 12 months after liver transplantation.

Everolimus is associated with a reduced incidence of cytomegalovirus infection following de novo cardiac transplantation. Transpl Infect Dis 2012; 15:150-62. [PMID: 23013440 DOI: 10.1111/tid.12007] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2011] [Revised: 04/05/2012] [Accepted: 05/27/2012] [Indexed: 01/01/2023]
Abstract
BACKGROUND Cytomegalovirus (CMV) causes several complications following cardiac transplantation including cardiac allograft vasculopathy. Previous studies suggested that immunosuppressive treatment based on everolimus might reduce CMV infection. Aiming to better characterize the action of everolimus on CMV and its interplay with patient/recipient serology and anti-CMV prophylaxis, we analyzed data from 3 large randomized studies comparing various everolimus regimens with azathioprine (AZA)- and mycophenolate mofetil (MMF)-based regimens. METHODS CMV data were analyzed from 1009 patients in 3 trials of de novo cardiac transplant recipients who were randomized to everolimus 1.5 mg/day, everolimus 3 mg/day, or AZA 1-3 mg/kg/day, plus standard-dose (SD) cyclosporine (CsA; study B253, n = 634); everolimus 1.5 mg/day plus SD- or reduced-dose (RD)-CsA (study A2403, n = 199); and everolimus 1.5 mg/day plus RD-CsA or MMF plus SD-CsA (study A2411, n = 176). RESULTS In study B253, patients allocated to everolimus experienced almost a 70% reduction in odds of experiencing CMV infection compared with AZA (P < 0.001). In study A2403, CMV infection was low in both everolimus arms, irrespective of CsA dosing, and in study A2411, patients allocated to everolimus experienced an 80% reduction in odds of experiencing CMV infection, compared with MMF (P < 0.001). CMV syndrome/disease was rare and less frequent in everolimus-treated patients. Subgroup analyses showed that the benefit everolimus provides, in terms of CMV events, is retained in CMV-naïve recipients and is independent of anti-CMV prophylaxis or preemptive approaches. CONCLUSIONS Everolimus is associated with a lower incidence of CMV infection compared with AZA and MMF, which combined with its immunosuppressive efficacy and antiproliferative effects may positively impact long-term outcomes.

Abstract
Acute renal failure (ARF) was a frequent complication after orthotopic liver transplantation (OLT) when ARF was defined by a calculated glomerular filtration rate decrease of >50% or by a doubled serum creatinine above 2.5 mg/dL within the first week after OLT. We analyzed 1352 liver transplant recipients in retrospective fashion with regard to the incidence, etiology, therapy, and outcome of ARF; 162 patients developed ARF within the first week after OLT (12%), among whom 157 patients (97%) were recompensated by postoperative day 28. Altogether 52 patients (32%) received an average of 6 hemodialysis treatments, excluding the 5 patients (3%) who developed end-stage renal failure. Risk factors for this complication included hepatorenal syndrome type II, a glomerular filtration rate of <50 mL/min, and a diagnosis of hepatitis C.

Abstract
Acute cellular rejection represents the most important single risk factor for the occurrence of chronic rejection after organ transplantation. We correlated late acute rejections with the occurrence of chronic graft failure after liver transplantation. We followed 1426 liver transplants for late acute rejection episodes defined as occurring >3 months after OLT. The overall incidence of chronic rejection in our patient population was 3.7%. In summary, we observed a predictive increase of transaminase levels prior to routine biopsies among patients with histologic evidence of late acute rejections. In contrast to other organ systems, late acute rejection episodes were not associated with the occurrence of chronic graft deterioration in liver grafts.

Abstract
The aim of this study was to evaluate the success of steroid (PRED) withdrawal due to replacement by mycophenolate mofetil (MMF) in orthotopic liver transplant (OLT) recipients with autoimmune hepatitis (AIH). Thirty patients with AIH > 12 months after OLT randomized to receive either PRED and tacrolimus (TAC) or MMF and TAC were followed for 24 months. Withdrawal of steroids showed no difference regarding graft and patient survival. Also we demonstrated significantly lower glucose levels with lower HbA1c and a reduced need for insulin as well as a significantly lower serum cholesterol in the MMF group. Patients without steroids showed a lower incidence of osteopenia. Maintenance therapy in OLT patients with AIH may be performed safely using MMF instead of prednisone.

Abstract
The early safety and efficacy of tacrolimus after liver transplantation has been shown in two multicenter trials. Herein, we report our single-center long-term follow-up of a randomized controlled trial. As part of a European multicenter trial, 121 patients entered the study at our institution and were randomly assigned to receive either tacrolimus and steroids (n=61) or a quadruple protocol (n=60) using ciclosporin A, steroids, azathioprine, and antithymocyte globulin (ATG). Twelve-year figures of patient survival were 74% in the tacrolimus group and 66% in the cyclosporine-based group. Graft survival after 12 years was 69% in the tacrolimus group compared to 56% in the cyclosporin-based group (not significant, p=0.15). The total rate of graft loss and retransplantation decreased significantly in the tacrolimus arm (p<0.05). De novo malignancies increased significantly in the ciclosporin-based group and dominated as single cause of death beyond 5 years posttransplant. The use of tacrolimus after liver transplantation resulted in a decreased rate of graft loss over the long-term. An increased number of de novo malignancies in the ciclosporin-based group may be attributable to the use of ATG as induction therapy.

Abstract
BACKGROUND AND OBJECTIVE Intestinal transplantation (ITx) is the only causal therapy of short bowel syndrome (SBS). Long-term survival after ITx has been improved significantly during the last years. The experience with ITx at the Charite, Campus Virchow Klinikum, are described and discussed. PATIENTS AND METHODS Twelve isolated ITx and one multivisceral transplantation (including stomach, pancreatodudenal complex, small intestine, liver, ascending colon, right kidney, and adrenal gland) were performed. Mean recipient age was 37.7+/-10.6 yrs (median: 35 yrs; range: 27 - 58 yrs; M:F = 8:5). All patients had irreversible SBS (0 - 30 cm residual bowel length; mean: 11.8+/-11.4 cm; median: 13 cm). RESULTS 6-months and 1-year patient and graft survival were 85 % (11/13) and 77 % (10/13), respectively. Reasons for graft loss and patient death were necrotizing enterocolitis, severe, muromonab-resistent, acute rejection, and graft ischemia due to complex coagulopathy. All other patients had good long-term outcome. They received enteral nutrition at six hours after operation and were persistently off total parenteral nutrition (TPN) by week two after ITx. CONCLUSION ITx as established in our centre, with 1-year-patient and graft survival rates of 77 %, reflects current international standard. ITx is complementary to conservative and other operative methods of treating SBS. Referral and indication criteria need wider dissemination to prevent life-threatening complications of TPN.

Abstract
INTRODUCTION Due to increasing availability, easier access, and rapid growth of information, the Internet has become an important source of medical information. We analyzed the value of Internet sites and the content of their medical information for physicians and patients using the example "soft tissue sarcoma." METHODS Sixteen German and English Internet search engines were used to evaluate the retrieved internet sites regarding their target group, publisher, contents, and topicality. RESULTS The majority of retrieved websites were in English compared to significantly fewer in German. The content of information was more valuable for patients and physicians on the English websites compared to the German ones. Even if many of the evaluated websites originated from medical organizations or universities, the amount of information was limited and often not up to date. CONCLUSION Information on the web is widespread, but for special queries too limited and difficult to identify. An improvement of available websites is needed, especially those maintained by universities and nonprofit medical organizations. The retrieval software should be optimized to ease identification of information, which should be validated by a recognized standard.
