A case report and review of rheumatoid arthritis co-occurring with tuberous sclerosis complex, a rare occurrence.

Rheumatoid arthritis (RA) is a common autoimmune disease. Tuberous sclerosis complex(TSC) is a rare autosomal dominant disorder. We report a case of RA with TSC. The patient was a 46-year-old woman with polyarthritis and cough symptoms, rheumatoid arthritis associated interstitial lung disease (RA-ILD) was initially considered, and after more than 3 months of anti-rheumatic treatment, the patient still had cough, and further examination revealed that the patient had lymphangioleiomyomatosis in the lungs, hepatic and renal angiomyolipomas, multiple subependymal nodules, Vertebral osteosclerotic nodules, as well as facial angiofibromas and periungual fibroma, RA was finally diagnosed with TSC, and everolimus 10mg qd was added to anti-rheumatic therapy for 1 month, and the patient's cough symptoms were relieved.

Physical activity levels are positively related to progression-free survival and reduced adverse events in advanced ER+ breast cancer.

BACKGROUND: Increased levels of physical activity are associated with a reduction of breast cancer mortality, especially in postmenopausal women with positive hormone receptor status. So far, previous observational case-control and cohort studies have focused on associations between overall leisure time physical activity and survival of women with breast cancer in general. METHODS: In this multicenter prospective cohort study, conducted in Germany between 30th August 2012 to 29th December 2017, we investigated general physical activity in a homogenous sample of n = 1440 postmenopausal women with advanced (inoperable locally advanced or metastatic), hormone receptor-positive breast cancer receiving the same therapy (everolimus and exemestane). Self-reported physical activity was assessed using the Godin Leisure Time Exercise Questionnaire (GLTEQ) before and every 3 months during treatment. Participants were then classified into "active" and "insufficiently active" to screen their activity behavior the week prior to medical treatment. In addition, changes in physical activity patterns were assessed. Adjusted Cox regression analyses were performed for the activity categories to determine hazard ratios (HR). Besides progression-free survival (PFS), adverse events (AEs), QoL, and fatigue were assessed every 3 months until study termination. RESULTS: Compared to "insufficiently active" patients, "active" individuals indicated a significantly longer PFS (HR: 0.84 [0.74; 0.984], p = .0295). No significant differences were observed for changes of physical activity behavior. Patients who reported to be "active" at baseline revealed significantly fewer AEs compared to "insufficiently" active patients. In detail, both severe and non-severe AEs occurred less frequently in the "active" patients group. In line with that, QoL and fatigue were better in physical "active" patients compared to their insufficient active counterparts at the last post-baseline assessment. Participants who remained or become active indicated less AEs, a higher QoL, and reduced fatigue levels. CONCLUSIONS: Physical activity behavior prior to medical treatment might have prognostic value in patients with advanced breast cancer in terms of extending the PFS. Moreover, physical activity before and during treatment may reduce treatment-related side effects and improve patients' QoL and fatigue. TRIAL REGISTRATION: EUPAS9462.

Neoadjuvant everolimus in renal angiomyolipoma with or without tuberous sclerosis complex: Results from a multicenter, retrospective study.

OBJECTIVES: To assess the efficacy and safety of preoperative neoadjuvant everolimus in renal angiomyolipomas (AML) patients with or without Tuberous Sclerosis Complex (TSC). MATERIALS AND METHODS: This multi-institutional retrospective study enrolled renal AML patients who underwent partial nephrectomy (PN) or total nephrectomy after receiving at least 1 month of pre-operative everolimus. Imaging evaluations were collected before and after treatment, along with demographic, surgical, and follow-up information. The primary outcome was tumor volume reduction of ≥25%, with additional outcomes including recurrence, perioperative outcomes, renal function, and safety. RESULTS: From January 2015 to July 2022, 68 renal AML patients were studied-41 with TSC and 27 without. During everolimus treatment, 61.0% (25/41) of TSC patients and 44.4% (12/27) of non-TSC patients achieved tumor reduction of ≥25%. Additionally, 41.5% (17/41) of TSC patients and 18.5% (5/27) of non-TSC patients achieved a ≥ 50% reduction. Three TSC patients and 1 non-TSC patient discontinued treatment due to side-effects. Most patients (92.7% TSC, 85.2% non-TSC) underwent PN. After everolimus treatment, the necessary total nephrectomy decreased to 41.2% (7/17) from baseline. Postoperatively, 1 grade 3 and 3 grade 2 complications occurred, with no grade 4 or 5 complications. After a median follow-up of 24 months, only 1 TSC patient recurred with a diameter >3 cm. Retrospective nature is the major limitation of this study. CONCLUSION: Everolimus was effective and well-tolerated in neoadjuvant treatment for renal AML, especially in TSC patients. This neoadjuvant combination strategy of everolimus and PN could effectively controls recurrence and preserves renal function.

Peptide Receptor Radionuclide Therapy or Everolimus in Metastatic Neuroendocrine Tumors: The SeqEveRIV Study, a National Study from the French Group of Endocrine Tumors and Endocan-RENATEN Network.

Everolimus and peptide receptor radionuclide therapy (PRRT, 177Lu-DOTATATE) are 2 treatments recommended in guidelines for gastroenteropancreatic metastatic neuroendocrine tumors. However, the best treatment sequence remains unknown. Methods: We designed a retrospective multicenter study that included patients from the national prospective database of the Groupe d'Étude des Tumeurs Endocrines who had been treated using everolimus and PRRT between April 2004 and October 2022. The primary aim was to compare the 2 treatments (everolimus and PRRT) in terms of efficacy and safety, and the secondary aim was to evaluate the sequences (PRRT followed by everolimus or everolimus followed by PRRT) based on overall progression-free survival (PFS) (PFS during first treatment + PFS during second treatment) in patients with metastatic neuroendocrine tumors. Results: Both treatments were used for 84 patients. The objective response rate and median PFS were 5 (6.0%) and 16.1 mo (95% CI, 11.5-20.7 mo), respectively, under everolimus and 19 (22.6%) and 24.5 mo (95% CI, 17.7-31.3 mo), respectively, for PRRT. The safety profile was also better for PRRT. Median overall PFS was 43.2 mo (95% CI, 33.7-52.7 mo) for the everolimus-PRRT sequence and 30.6 mo (95% CI, 17.8-43.4 mo) for the PRRT-everolimus sequence (hazard ratio, 0.69; 95% CI, 0.39-1.24; P = 0.22). Conclusion: PRRT was more effective and less toxic than everolimus. Overall PFS was similar between the 2 sequences, suggesting case-by-case discussion if the patient is eligible for both treatments, but PRRT should be used first when an objective response is needed or in frail populations.

Adjuvant Everolimus in Non-Clear Cell Renal Cell Carcinoma: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Clinical trial data on adjuvant therapy in patients with non-clear cell renal cell carcinoma (RCC) are scant. Objective: To evaluate the effect of adjuvant everolimus after nephrectomy on recurrence-free survival (RFS) and overall survival (OS) in patients with localized papillary and chromophobe RCC. Design, Setting, and Participants: This prespecified subgroup analysis of a phase 3 randomized clinical trial, EVEREST, included patients enrolled between April 1, 2011, and September 15, 2016. Eligible patients had fully resected RCC at intermediate-high risk (pT1 grade 3-4, N0 to pT3a grade 1-2, N0) or very-high risk (pT3a grade 3-4 to pT4 any grade or N+) for recurrence who had received radical or partial nephrectomy. Final analyses was completed in March 2022. Intervention: The intervention group received 54 weeks of everolimus (10 mg orally daily); the control group received a matching placebo. Main Outcomes and Measures: The main outcomes were RFS, OS, and rates of adverse events. For testing the hazard ratio (HR) for treatment effect, a Cox regression model was used for both OS and RFS. Results: Of 1545 adult patients with treatment-naive, nonmetastatic, fully resected RCC in EVEREST, 109 had papillary RCC (median [range] age, 60 [19-81] years; 82 [75%] male; 50 patients [46%] with very high-risk disease) and 99 had chromophobe RCC (median [range] age 51 [18-71] years; 53 [54%] male; 34 patients [34%] with very high-risk disease). Among 57 patients with papillary RCC in the intervention group, 26 (46%) completed 54 weeks of treatment, and among 53 patients with chromophobe RCC in the intervention group, 26 (49%) completed 54 weeks of treatment. With a median (IQR) follow-up of 76 (61-96) months, adjuvant everolimus did not improve RFS compared with placebo in either papillary RCC (5-year RFS: 62% vs 70%; HR, 1.19; 95% CI, 0.61-2.33; P = .61) or chromophobe RCC (5-year RFS: 79% vs 77%; HR, 0.89; 95% CI, 0.37-2.13; P = .79). In the combined non-clear RCC cohort, grade 3 or higher adverse events occurred in 48% of patients who received everolimus and 9% of patients who received placebo. Conclusions and Relevance: In this clinical trial assessing the use of adjuvant everolimus, postoperative everolimus did not show evidence of improved RFS among patients with papillary or chromophobe RCC, and results from the study do not support adjuvant everolimus for this cohort. However, since the lower bounds of the 95% CIs were 0.61 and 0.89, respectively, potential treatment benefit in these subgroups cannot be ruled out.

First-in-Human Evaluation of a Polymer-Free Everolimus-Eluting Stent Using a Titanium Dioxide Film.

BACKGROUND: In patients with coronary artery disease treated with permanent polymer-coated drug-eluting stents (DES), the persistent presence of a less biocompatible polymer might delay arterial healing. Thin strut polymer-free DES have the potential to improve clinical outcomes and reduce the duration of dual antiplatelet therapy (DAPT). The purpose of this first-in-human study was to assess the safety and effectiveness of a novel polymer-free DES in patients with de novo coronary lesions. The TIGERevolutioN® stent (CG Bio Co., Ltd., Seoul, Korea) consists of a cobalt chromium platform with a strut thickness of 70 µm and a surface treated with titanium dioxide onto which everolimus-eluting stent (EES) is applied abluminally (6 µg/mm of stent length) without utilization of a polymer. METHODS: A total of 20 patients were enrolled, with de novo coronary lesions (stable or unstable angina) and > 50% diameter stenosis in a vessel 2.25 to 4.00 mm in diameter and ≤ 40 mm in length for angiographic, optical coherence tomography (OCT), and clinical assessment at 8 months. All patients received DAPT after stent implantation. The primary endpoint was angiographic in-stent late lumen loss (LLL) at 8 months. RESULTS: Twenty patients with 20 lesions were treated with TIGERevolutioN®. At 8 months, in-stent LLL was 0.7 ± 0.4 mm. On OCT, percent area stenosis was 29.2 ± 9.4% and stent strut coverage was complete in all lesions. No adverse cardiovascular event occurred at 8 months. CONCLUSION: The new polymer-free EES was safe and effective with low LLL and excellent strut coverage at 8 months of follow-up.

[A Case of Successful Treatment of Severe Hyperlipidemia After Heart Transplantation With Inclisiran].

The prognosis after heart transplantation continues to improve. Therefore, the prevention of chronic post-transplant sequelae, such as chronic kidney disease, allograft vasculopathy, and malignancies is becoming increasingly important. Everolimus, an inhibitor of the mammalian target of rapamycin (mTOR), is increasingly used for immunosuppression after heart transplantation. However, everolimus may cause a characteristic complex of adverse effects, including dyslipidemia. Currently there are no guidelines for the long-term screening and treatment of dyslipidemia in heart transplant recipients treated with everolimus. This article presents a clinical case of hypercholesterolemia that developed after the start of the everolimus treatment in a heart recipient. The patient was a 39-year-old man who underwent orthotopic heart transplantation for ischemic cardiomyopathy in 2012 (at the age of 27). In 2019, the patient's immunosuppressive therapy was converted from mycophenolate mofetil to everolimus due to the development of cardiac allograft vasculopathy. The change in the immunosuppressive therapy was associated with increases in total cholesterol and low-density lipoprotein cholesterol, which were not reversed with a combined lipid-lowering therapy (maximum doses of rosuvastatin, ezetimibe, fenofibrate). A decrease in lipid levels was achieved with a blocker of hepatic proprotein convertase subtilisin/kexin type 9 synthesis at the level of microribonucleic acid (inclisiran). This case demonstrates the difficulties in correcting dyslipidemia in patients with cardiac allograft, since the treatment with the immunosuppressant everolimus worsens existing dyslipidemia. However, the combination lipid-lowering therapy, that affects various elements of the pathogenesis (specifically, the combined inhibition of hydroxymethylglutaryl-CoA reductase with a statin, cholesterol absorption from the small intestine with ezetimibe, and PCSK9 messenger RNA with inclisiran), provides an effective control of blood lipids and minimizing the adverse effects of immunosuppressive therapy, such as cardiac allograft vasculopathy.

Pharmacokinetic variability of everolimus and impact of concomitant antiseizure medications in patients with tuberous sclerosis complex: A retrospective study of therapeutic drug monitoring data in Denmark and Norway.

The mTOR-inhibitor everolimus is a precision drug with antiepileptogenic properties approved for treatment of epilepsy in persons with tuberous sclerosis complex (TSC) in combination with other antiseizure medications (ASMs). However, the pharmacokinetic variability of everolimus is scarcely described, and the available information on pharmacokinetic interactions is scarce. The purpose of this study was to investigate pharmacokinetic variability of everolimus in patients with TSC, and the impact of age, sex and comedication. In this retrospective observational study we used anonymized data from medical records of patients with TSC using everolimus in Norway and Denmark, 2012 to 2020. Long-term therapeutic drug monitoring (TDM) identified inter-patient and intra-patient variability. The study included 59 patients, (36 females (61%)), median age 22 (range 3-59 years). Polytherapy was used in 50 patients (85%). The most frequently used ASMs were lamotrigine (n = 21), valproate (n = 17), and levetiracetam (n = 13). Blood concentrations of everolimus were measured in all patients. Pharmacokinetic variability of everolimus between patients was extensive, as demonstrated by a 24-fold variability from minimum-maximum concentration/dose (C/D)-ratios. The coefficient of variation (CV) for intra-patient (n = 59) and inter-patient variability (n = 47, ≥3 measurements) was 40% and 43%, respectively. The C/D-ratio of everolimus was 50% lower in 13 patients (22%) using enzyme-inducing ASMs compared to the 30 patients who did not (0.7 vs 1.4 ng/mL mg, P < .05). Age and sex were not significantly associated with changes in C/D-ratios of everolimus. Long-term TDM identified extensive variability in concentrations over time for everolimus both within and between patients, where comedication with enzyme-inducing ASMs was an important contributing factor. The findings suggest a need for TDM in patients with TSC treated with everolimus.

[Systemic treatment of patients with metastatic neuroendocrine Neoplasia]. / Systemtherapie von neuroendokrinen Neoplasien.

Due to the complexity and heterogeneity of metastatic NEN an interdisciplinary expert team should be involved in an individualized treatment strategy. SSA is the mainstay of antisecretory treatment in most functioning tumors. In antiproliferative intention SSA are first line treatment in receptor positive low proliferative NET. In intestinal metastatic disease PRRT is best established second line treatment. Further options are Everolimus (labeled) and tyrosine kinase inhibitors (off-label). Everolimus is the only approved drug for antiproliferative treatment in patients with metastatic lung NET, whereas in pancreatic NET more therapeutic options are available (SSA, chemotherapy, PRRT, Sunitinib, Everolimus) without a standard of best sequence. In patients with metastatic NEC standard first line treatment (platinum + etoposide) has not changed for decades and new treatment options for this fatal disease are urgently needed. Benefit of immunotherapy is limited to a small subset of patients - new combinations are under investigation. This review summarizes the standard of care, criteria of treatment selection and new developments for systemic therapy in patients with metastatic NEN.

Early Conversion to Everolimus Within 180 Days of Living Donor Liver Transplantation.

BACKGROUND: Early conversion to Everolimus (EVR) post deceased donor liver transplant has been associated with improved renal function but increased rejection. Early EVR conversion has not been evaluated after living donor liver transplant (LDLT). A retrospective cohort study was conducted to compare the rate of rejection and renal function in patients converted to EVR early post-LDLT to patients on calcineurin inhibitors (CNIs). METHODS: This was a single center retrospective cohort study of adult LDLT recipients between January 2012 and July 2019. Patients converted to EVR within 180 days of transplant were compared to patients on CNIs. The primary endpoint was biopsy proven acute rejection (BPAR) at 24 months posttransplant. Key secondary endpoints included eGFR at 24 months, change in eGFR, adverse events, and all-cause mortality. RESULTS: From a total of 173 patients involved in the study: 58 were included in the EVR group and 115 in the CNI group. Median conversion to EVR was 26 days post-LDLT. At 24 months, there was no difference in BPAR (22.7% EVR vs. 19.1% CNI, p = 0.63). Median eGFR at 24 months posttransplant was not significantly different (68.6 [24.8 to 112.4] mL/min EVR vs. 75.9 [35.6-116.2] mL/min CNI, p = 0.103). Change in eGFR from baseline was worse in the EVR group (-13.0 [-39.9 to 13.9] mL/min EVR vs. -5.0 [-31.2 to 21.2] mL/min CNI, p = 0.047). Median change from conversion to 24 months posttransplant (EVR group only) was -3.43 mL/min/1.73 m2 (-21.0 to 9.6). CONCLUSIONS: Early EVR conversion was not associated with increased risk of rejection among LDLT recipients. Renal function was not impacted. EVR may be considered as an alternative after LDLT in patients intolerant of CNIs.

Radiotherapy for subependymal giant cell astrocytoma: time to challenge a historical ban? A case report and review of the literature.

BACKGROUND: Subependymal giant cell astrocytoma is a benign brain tumor that occurs in patients with tuberous sclerosis complex. Surgical removal is the traditional treatment, and expert opinion is strongly against the use of radiotherapy. Recently, success has been reported with the mTor inhibitor everolimus in reducing tumor volume, but regrowth has been observed after dose reduction or cessation. CASE REPORT: We present the case of a 40-year-old Asian female patient treated successfully for growing bilateral subependymal giant cell astrocytoma with fractionated stereotactic radiotherapy before everolimus became available. After a follow-up of 8 years, everolimus was administered for renal angiomyolipoma and the patient was followed up until 13 years after radiotherapy. Successive magnetic resonance imaging demonstrated an 80% volume reduction after radiotherapy that increased to 90% with everolimus. A review of the literature was done leveraging Medline via PubMed, and we assembled a database of 1298 article references and 780 full-text articles in search of evidence for contraindicating radiotherapy in subependymal giant cell astrocytoma. Varying results of single-fraction radiosurgery were described in a total of 13 cases. Only in two published cases was the radiation dose of fractionated radiotherapy mentioned. One single publication mentions an induced secondary brain tumor 8 years after whole-brain radiotherapy. CONCLUSION: There is no evidence of contraindication and exclusion of fractionated radiotherapy in treating subependymal giant cell astrocytoma. Our experience demonstrates that subependymal giant cell astrocytoma, as other benign intracranial tumors, responds slowly but progressively to radiotherapy and suggests that fractionated stereotactic radiotherapy holds promise to consolidate responses obtained with mTor inhibitors avoiding regrowth after cessation.

Quantitative SSTR-PET/CT: a potential tool for predicting everolimus response in neuroendoctine tumour patients.

BACKGROUND: This study aimed to assess 68Ga-DOTA-TATE (-TOC) PET/CT quantitative parameters in monitoring and predicting everolimus response in neuroendocrine tumor (NET) patients with hepatic metastases (NELM). PATIENTS AND METHODS: This retrospective analysis included 29 patients with 62 target lesions undergoing everolimus treatment and pre-therapy, and follow-up 68Ga-DOTA-TATE (-TOC) PET/CT scans. Response evaluation utilized progression-free survival (PFS) categorized as responders (R; PFS > 6 months) and non-responders (NR; PFS ≤ 6 months). Lesion size and density, along with maximum and median standardize uptake value (SUV) in target lesions, liver, and spleen were assessed. Tumor-to-spleen (T/S) and tumor-to-liver (T/L) ratios were calculated, including the tumor-to-spleen (T/S) ratio and tumor-to-liver (T/L) ratio (using SUVmax/SUVmax, SUVmax/SUVmean, and SUVmean/SUVmean). RESULTS: PET/CT scans were acquired 19 days (interquartile range [IQR] 69 days) pre-treatment and 127 days (IQR 74 days) post-starting everolimus. The overall median PFS was 264 days (95% CI: 134-394 days). R exhibited significant decreases in Tmax/Lmax and Tmean/Lmax ratios compared to NR (p = 0.01). In univariate Cox regression, Tmean/Lmax ratio was the sole prognostic parameter associated with PFS (HR 0.5, 95% CI 0.28-0.92, p = 0.03). Percentage changes in T/L and T/S ratios were significant predictors of PFS, with the highest area under curve (AUC) for the percentage change of Tmean/Lmax (AUC = 0.73). An optimal threshold of < 2.5% identified patients with longer PFS (p = 0.003). No other imaging or clinical parameters were predictive of PFS. CONCLUSIONS: This study highlights the potential of quantitative SSTR-PET/CT in predicting and monitoring everolimus response in NET patients. Liver metastasis-to-liver parenchyma ratios outperformed size-based criteria, and Tmean/Lmax ratio may serve as a prognostic marker for PFS, warranting larger cohort investigation.

Phase III Randomized, Placebo-Controlled Trial of Endocrine Therapy ± 1 Year of Everolimus in Patients With High-Risk, Hormone Receptor-Positive, Early-Stage Breast Cancer.

PURPOSE: Phosphatidylinositol 3-kinase/AKT-serine threonine kinase/mammalian target of rapamycin (mTOR) pathway abnormalities contribute to endocrine resistance. Everolimus, an mTOR inhibitor, improved progression-free survival in hormone receptor-positive metastatic breast cancer (BC) when combined with endocrine therapy (ET). In this phase III randomized, placebo-controlled trial, we assessed the efficacy of everolimus + ET as adjuvant therapy in high-risk, hormone receptor-positive, human epidermal growth factor receptor 2-negative BC after adjuvant/neoadjuvant chemotherapy. METHODS: Patients were randomly assigned 1:1 to physician's choice ET and 1 year of everolimus (10 mg orally once daily) or placebo stratified by risk group. The primary end point was invasive disease-free survival (IDFS) evaluated by a stratified log-rank test with the hazard ratio (HR) estimated by Cox regression. Subset analyses included preplanned evaluation by risk group and exploratory analyses by menopausal status and age. Secondary end points included overall survival (OS) and safety. Everolimus did not improve IDFS/OS when added to ET in patients with early-stage high-risk, hormone receptor-positive BC. RESULTS: One thousand and nine hundred thirty-nine patients were randomly assigned with 1,792 eligible for analysis. Overall, no benefit of everolimus was seen for IDFS (HR, 0.94 [95% CI, 0.77 to 1.14]) or OS (HR, 0.97 [95% CI, 0.75 to 1.26]). The assumption of proportional hazards was not met suggesting significant variability in the HR over time since the start of treatment. In an unplanned subgroup analysis among postmenopausal patients (N = 1,221), no difference in IDFS (HR, 1.08 [95% CI, 0.86 to 1.36]) or OS (HR, 1.19 [95% CI, 0.89 to 1.60]) was seen. In premenopausal patients (N = 571), everolimus improved both IDFS (HR, 0.64 [95% CI, 0.44 to 0.94]) and OS (HR, 0.49 [95% CI, 0.28 to 0.86]). Treatment completion rates were lower in the everolimus arm compared with placebo (48% v 73%) with higher grade 3 and 4 adverse events (35% v 7%). CONCLUSION: One year of adjuvant everolimus + ET did not improve overall outcomes. Subset analysis suggests mTOR inhibition as a possible target for patients who remain premenopausal after chemotherapy.

Adjuvant Everolimus in Patients with Completely Resected, Very High-risk Renal Cell Carcinoma of Clear Cell Histology: Results from the Phase 3 Placebo-controlled SWOG S0931 (EVEREST) Trial.

BACKGROUND AND OBJECTIVE: EVEREST is a phase 3 trial in patients with renal cell cancer (RCC) at intermediate-high or very high risk of recurrence after nephrectomy who were randomized to receive adjuvant everolimus or placebo. Longer recurrence-free survival (RFS) was observed with everolimus (hazard ratio [HR] 0.85, 95% confidence interval [CI] 0.72-1.00; p = 0.051), but the nominal significance level (p = 0.044) was not reached. To contextualize these results with positive phase 3 trials of adjuvant sunitinib and pembrolizumab, we conducted a secondary analysis in a similar population of EVEREST patients with very high-risk disease and clear cell histology. METHODS: Postnephrectomy patients with any clear cell component and very high-risk disease, defined as pT3a (grade 3-4), pT3b-c (any grade), T4 (any grade), or node-positive status (N+), were identified. A Cox regression model stratified by performance status was used to compare RFS and overall survival (OS) between the treatment arms. KEY FINDINGS AND LIMITATIONS: Of 1499 patients, 717 had clear cell histology and very high-risk disease; 699 met the eligibility criteria, of whom 348 were randomized to everolimus arm, and 351 to the placebo arm. Patient characteristics were similar between the arms. Only 163/348 (47%) patients in the everolimus arm completed all treatment as planned, versus 225/351 (64%) in the placebo arm. Adjuvant everolimus resulted in a statistically significant improvement in RFS (HR 0.80; 95%CI 0.65-0.99, p = 0.041). Evidence of a survival benefit was not seen (HR 0.85; 95%CI 0.64-1.14, p = 0.3) CONCLUSIONS AND CLINICAL IMPLICATIONS: In patients with clear cell RCC at very high-risk for recurrence, adjuvant everolimus resulted in significantly improved RFS compared to placebo but resulted in a high discontinuation rate due to adverse events. Although the treatment HR for OS was consistent with RFS findings, it did not reach statistical significance. With a focus on risk stratification tools and/or biomarkers to minimize toxicity risk in those not likely to benefit, this information can help inform the design of future adjuvant trials in high-risk RCC.

Treatment of newly diagnosed moderate or severe chronic graft-versus-host disease with prednisone and everolimus (PredEver first): a prospective multicenter phase IIA study.

Although most patients with chronic graft-versus-host disease (cGVHD) show initial response to first-line therapy, long-term clinically meaningful success of first-line treatment remains rare. In a prospective multicentre phase II trial in 6 German centers, patients with newly diagnosed moderate or severe cGVHD received prednisone and everolimus for 12 months followed by a 1-year follow-up period. Primary endpoint was treatment success (TS) at 6 months defined as patient being alive, achieving PR or CR of cGVHD, having no relapse of underlying disease and requiring no secondary treatment for cGVHD. Of the 34 patients evaluable for efficacy, 19 (56%) had TS at 6 months with 22 and 52% of the patients in a CR and PR respectively. Overall 30 patients (88%) had a CR or PR as best response, nearly all responses (29/30) occurring within the first 6 weeks of treatment. The cumulative incidence of treatment failure at 1 year was 63%, corresponding to 37% TS. Predefined safety endpoint (thrombotic microangiopathy, pneumonitis, and avascular necrosis) were not observed in any patient. Addition of everolimus to prednisolone is well tolerated and may improve long-term treatment success. Larger studies are necessary to ascertain the possible role of everolimus in first-line treatment of cGVHD.

Platinum chromium everolimus-eluting stents for the treatment of (complex) coronary artery disease; from SYNERGY™ to the MEGATRON™.

INTRODUCTION: The introduction of drug-eluting coronary stents (DES) into clinical practice in 2002 represented a major milestone in the treatment of obstructive coronary artery disease. Over the years, significant advances in polymer coating and in antiproliferative agent technology have further improved the safety and clinical performance of newer-generation DES. AREAS COVERED: Development of platinum chromium (PtCr) alloys with high radial strength and high radiopacity have enabled the design of new, thin-strut, flexible, and highly trackable stent platforms, while simultaneously improving stent visibility. These advances have facilitated complex percutaneous treatment of a diverse population of patients in clinical practice. This review will provide an overview of the evolution in PtCr everolimus-eluting stents from PROMUS Element™ to SYNERGY™ to the recently introduced SYNERGY MEGATRON™. The clinical data will be summarized and put into perspective, especially focusing on the role of the SYNERGY™ and MEGATRON™ platforms in the treatment of complex coronary artery disease and high-risk patients. EXPERT OPINION: The SYNERGY™ stent demonstrates favorable clinical efficacy and safety outcome data, and whilst the clinical data on MEGATRON™ are sparse, early experience is promising. The specific overexpansion capabilities, visibility, and radial strength of the MEGATRON™ are attractive features for complex coronary interventions.

Prognostic value of EndoPredict test in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative primary breast cancer screened for the randomized, double-blind, phase III UNIRAD trial.

BACKGROUND: The purpose of this study was to evaluate the prognostic value of the multigene EndoPredict test in prospectively collected data of patients screened for the randomized, double-blind, phase III UNIRAD trial, which evaluated the addition of everolimus to adjuvant endocrine therapy in high-risk, hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. PATIENTS AND METHODS: Patients were classified into low or high risk according to the EPclin score, consisting of a 12-gene molecular score combined with tumor size and nodal status. Association of the EPclin score with disease-free survival (DFS) and distant metastasis-free survival (DMFS) was evaluated using Kaplan-Meier estimates. The independent prognostic added value of EPclin score was tested in a multivariate Cox model after adjusting on tumor characteristics. RESULTS: EndoPredict test results were available for 768 patients: 663 patients classified as EPclin high risk (EPCH) and 105 patients as EPclin low risk (EPCL). Median follow-up was 70 months (range 1-172 months). For the 429 EPCH randomized patients, there was no significant difference in DFS between treatment arms. The 60-month relapse rate for patients in the EPCL and EPCH groups was 0% and 7%, respectively. Hazard ratio (HR) supposing continuous EPclin score was 1.87 [95% confidence interval (CI) 1.4-2.5, P < 0.0001]. This prognostic effect remained significant when assessed in a Cox model adjusting on tumor size, number of positive nodes and tumor grade (HR 1.52, 95% CI 1.09-2.13, P = 0.0141). The 60-month DMFS for patients in the EPCL and EPCH groups was 100% and 94%, respectively (adjusted HR 8.10, 95% CI 1.1-59.1, P < 0.0001). CONCLUSIONS: The results confirm the value of EPclin score as an independent prognostic parameter in node-positive, hormone receptor-positive, HER2-negative early breast cancer patients receiving standard adjuvant treatment. EPclin score can be used to identify patients at higher risk of recurrence who may warrant additional systemic treatments.

Primary prophylaxis with mTOR inhibitor enhances T cell effector function and prevents heart transplant rejection during talimogene laherparepvec therapy of squamous cell carcinoma.

The application of mammalian target of rapamycin inhibition (mTORi) as primary prophylactic therapy to optimize T cell effector function while preserving allograft tolerance remains challenging. Here, we present a comprehensive two-step therapeutic approach in a male patient with metastatic cutaneous squamous cell carcinoma and heart transplantation followed with concomitant longitudinal analysis of systemic immunologic changes. In the first step, calcineurin inhibitor/ mycophenolic acid is replaced by the mTORi everolimus to achieve an improved effector T cell status with increased cytotoxic activity (perforin, granzyme), enhanced proliferation (Ki67) and upregulated activation markers (CD38, CD69). In the second step, talimogene laherparepvec (T-VEC) injection further enhances effector function by switching CD4 and CD8 cells from central memory to effector memory profiles, enhancing Th1 responses, and boosting cytotoxic and proliferative activities. In addition, cytokine release (IL-6, IL-18, sCD25, CCL-2, CCL-4) is enhanced and the frequency of circulating regulatory T cells is increased. Notably, no histologic signs of allograft rejection are observed in consecutive end-myocardial biopsies. These findings provide valuable insights into the dynamics of T cell activation and differentiation and suggest that timely initiation of mTORi-based primary prophylaxis may provide a dual benefit of revitalizing T cell function while maintaining allograft tolerance.

Topical everolimus therapy for epidermal nevi associated with woolly hair nevus in a patient with a mosaic HRAS mutation.

A patient with woolly hair nevus syndrome, presented with epidermal facial nevi by the age of 12 years. Despite transient improvement with topical 1% sirolimus cream, the facial nevus grew larger. The patient was then treated with topical 1% everolimus cream resulting in a reduction in the size of the nevus. This case highlights a novel use of topical 1% everolimus cream, which previously has not been used to treat epidermal nevi.
