Within the 2-year study period,as compared with placebo, everolimus slowed the increase in total kidney volume of patients with ADPKD but did not slow the progression of renal impairment [corrected]. (Funded by Novartis; EudraCT number, 2006-001485-16; ClinicalTrials.gov number, NCT00414440.)
The eLEcTRA trial compared efficacy and safety of letrozole combined with trastuzumab to letrozole alone in patients with HER2 and hormone receptor (HR) positive metastatic breast cancer (MBC). Patients were randomized to either letrozole alone (arm A, n = 31) or letrozole plus trastuzumab (arm B, n = 26) as first-line treatment. Additional 35 patients with HER2 negative and HR positive tumors received letrozole alone (arm C). Median time to progression in arm A was 3.3 months compared to 14.1 months in arm B (hazard ratio 0.67; p = 0.23) and 15.2 months in arm C (hazard ratio 0.71; p = 0.03). Clinical benefit rate was 39% for arm A compared to 65% in arm B (odds ratio 2.99, 95% CI 1.01-8.84) and 77% in arm C (odds ratio 5.34, 95% CI 1.83-15.58). The eLEcTRA trial showed that the combination of letrozole and trastuzumab is a safe and effective treatment option for patients with HER2 positive and HR positive MBC.
BackgroundPolyomavirus BK nephropathy (PyVAN) remains an important cause of early graft dysfunction and graft loss in kidney transplantation.MethodsIn this retrospective, single centre cohort study we studied the incidence and outcome of BK viral infection in 352 patients transplanted in 2008–2011.ResultsDuring follow-up viral replication was detected in 48 patients (13.6%); 22 patients (6.2%) had biopsy proven PyVAN.In multivariate logistic regression analyses risk factors for BK-viremia were lack of enrolment into randomized controlled trials (RCTs), biopsy proven acute rejections, cytomegaly virus (CMV) serostatus of both donor and recipient and previous transplantation.In patients without PyVAN reduction or switch of immunosuppression was associated with rapid viral clearance and stable graft function. In contrast, in most patients with PyVAN graft function deteriorated and 5 patients prematurely lost their allograft. Switch of immunosuppression to a low dose cyclosporine plus mTOR inhibitor based regimen in patients with PyVAN was safe, well tolerated and tended to be associated with a better short-term outcome in terms of graft function compared to reduction of existing immunosuppression alone.ConclusionsWith the lack of licensed anti-polyoma viral drugs reduction or conversion of immunosuppression remains the mainstay of therapy in patients with PyVAN. The combination of low dose cyclosporine plus mTOR inhibition appears to be safe and warrants further investigation.
†Members listed in the Appendix.The long-term effect of conversion from calcineurin inhibitor (CNI) therapy to an mTOR inhibitor requires clarification. Following completion of the 12-month, open-label, multicenter ZEUS study, in which 300 kidney transplant recipients were randomized to continue cyclosporine (CsA) or convert to everolimus at 4.5 months posttransplant, outcomes were assessed at month 36 (n = 284; 94.7%). CNI therapy was reintroduced in 28.4% of everolimus patients by month 36. The primary efficacy endpoint, estimated glomerular filtration rate (Nankivell, ANCOVA) was significantly higher with everolimus versus the CsA group at month 24 (7.6 mL/min/1.73 m 2 , 95%CI 4.3, 11.0 mL/min/ 1.73 m 2 ; p < 0.001) and month 36 (7.5 mL/min/1.73 m 2 , 95%CI 3.6, 11.4 mL/min/1.73 m 2 ; p < 0.001). The incidence of biopsy-proven acute rejection from randomization to month 36 was 13.0% in the everolimus arm and 4.8% in the CsA arm (p = 0.015). Patient and graft survival, as well as incidences of malignancy, severe infections and hospitalization, were similar between groups. Kidney transplant patients who are converted from CsA to everolimus at month 4.5 and who remain on everolimus thereafter may achieve a significant improvement in renal function that is maintained to 3 years. There was a significantly higher rate of rejection in the everolimus arm but this did not exert a deleterious effect by 3 years posttransplant.
Everolimus initiation with CNI withdrawal at Month 3 after kidney transplantation achieves a significant improvement in renal function at 12 months, with a similar rate of acute rejection.
