RESUMEN

BACKGROUND: Sirolimus is increasingly utilized in treating diseases associated with mTOR pathway overactivation. Despite its potential, the lack of evidence regarding its long-term safety across all age groups, particularly in pediatric patients, has limited its further application. This study aims to assess the long-term safety of sirolimus, with a specific focus on its impact on growth patterns in pediatric patients. METHODS: This pooled analysis inlcudes two prospective cohort studies spanning 10 years, including 1,738 participants (aged 5 days to 69 years) diagnosed with tuberous sclerosis and/or lymphangioleiomyomatosis. All participants were mTOR inhibitor-naive and received 1 mg/m²/day of sirolimus, with dose adjustments during a two-week titration period to maintain trough blood concentrations between 5 and 10 ng/ml (maximum dose 2 mg). Indicators of physical growth, hematopoietic, liver, renal function, and blood lipid levels were all primary outcomes and were analyzed. The adverse events and related management were also recorded. RESULTS: Sirolimus administration did not lead to deviations from normal growth ranges, but higher doses exhibited a positive association with Z-scores exceeding 2 SD in height, weight, and BMI. Transient elevations in red blood cell and white blood cell counts, along with hyperlipidemia, were primarily observed within the first year of treatment. Other measured parameters remained largely unchanged, displaying only weak correlations with drug use. Stomatitis is the most common adverse event (920/1738, 52.9%). In adult females, menstrual disorders were observed in 48.5% (112/217). CONCLUSIONS: Sirolimus's long-term administration is not associated with adverse effects on children's physical growth pattern, nor significant alterations in hematopoietic, liver, renal function, or lipid levels. A potential dose-dependent influence on growth merits further exploration. TRIAL REGISTRATION: Pediatric patients: Chinese clinical trial registry, No. ChiCTR-OOB-15,006,535. Adult patients: ClinicalTrials, No. NCT03193892.

RESUMEN

BACKGROUND: Evidence suggests that drug-coated balloons may benefit in-stent restenosis (ISR) treatment. However, the efficacy of new-generation sirolimus-coated balloon (SCB) compared with the latest generation drug-eluting stents (DESs) has not been studied in this setting. METHODS: All patients in the EASTBORNE (The All-Comers Sirolimus-Coated Balloon European Registry) and DEB-DRAGON (DEB vs Thin-DES in DES-ISR: Long Term Outcomes) registries undergoing percutaneous coronary intervention for DES-ISR were included in the study. The primary study end point was target lesion revascularization at 24 months. Secondary end points were major adverse cardiovascular events, all-cause death, myocardial infarction, and target vessel revascularization at 24 months. Our goal was to evaluate the efficacy and safety of SCB versus thin-struts DES in ISR at long-term follow-up. RESULTS: A total of 1545 patients with 1679 ISR lesions were included in the pooled analysis, of whom 621 (40.2%) patients with 621 lesions were treated with thin-strut DES and 924 (59.8%) patients with 1045 lesions were treated with SCB. The unmatched cohort showed no differences in the incidence of target lesion revascularization (10.8% versus 11.8%; P=0.568); however, there was a trend toward lower rates of myocardial infarction (7.4% versus 5.0%; P=0.062) and major adverse cardiovascular events (20.8% versus 17.1%; P=0.072) in the SCB group. After propensity score matching (n=335 patients per group), there were no significant differences in the rates of target lesion revascularization (11.6% versus 11.8%; P=0.329), target vessel revascularization (14.0% versus 13.1%; P=0.822), myocardial infarction (7.2% versus 4.5%; P=0.186), all-cause death (5.7% versus 4.2%; P=0.476), and major adverse cardiovascular event (21.5% versus 17.6%; P=0.242) between DES and SCB treatment. CONCLUSIONS: In patients with ISR, angioplasty with SCB compared with thin-struts DES is associated with comparable rates of target lesion revascularization, target vessel revascularization, myocardial infarction, all-cause death, and major adverse cardiovascular events at 2 years.

RESUMEN

BACKGROUND: Sirolimus-coated balloons (SCB) for the treatment of femoropopliteal (FP) lesions have not been systematically studied, but initial outcomes from early studies are promising. OBJECTIVES: The authors sought to evaluate the safety and efficacy of the SELUTION SLR SCB, composed of proprietary microreservoir technology combining sirolimus and biodegradable polymer, when used to treat mild-to-moderate FP disease in a Japanese population. METHODS: This multicenter, prospective, single-arm study (SELUTION SFA JAPAN) enrolled 134 patients with FP disease. It was independently adjudicated by an imaging core laboratory and clinical events committee. The primary endpoint was 12-month primary patency, defined as peak systolic velocity ratio ≥2.5 by duplex ultrasound and compared against a prespecified performance goal of 60% based on established angioplasty data. RESULTS: The mean age was 73.8 ± 6.9 years, and 60.3% of patients had diabetes mellitus. The mean lesion length was 127.4 ± 59.7 mm, 17.2% were chronic total occlusions, and 47.8% involved the popliteal artery. Data on 12-month restenosis were available in 127 patients (94.8%). The 12-month primary patency rate was 87.9%, and the freedom from clinically driven target lesion revascularization (CD-TLR) was 97.0% per Kaplan-Meier estimate. The major adverse event rate was 6.7%, driven by 4 CD-TLRs and 5 deaths, none of which were related to the device or procedure. Ankle-brachial index data improved significantly from 0.73 ± 0.16 at baseline to 0.96 ± 0.14 at 30 days postprocedure and was sustained through 12 months (0.94 ± 0.13). CONCLUSIONS: The SELUTION SFA JAPAN trial demonstrated that a novel SELUTION SCB is a safe and effective treatment option for FP disease in symptomatic patients.

RESUMEN

BACKGROUND: Rapamycin has been extensively utilized for coating coronary artery stents to reduce the occurrence of restenosis, yet there has been limited research on the potential harms of rapamycin-eluting stents. Herein, We report a case of eosinophilia and interstitial pneumonia caused by a cobalt-based alloy stent eluted with rapamycin. CASE PRESENTATION: The patient was admitted due to fever, cough, and expectoration symptoms. Previously, the patient had undergone a procedure of percutaneous coronary stent implantation in our hospital's cardiology department, which led to a gradual rise in blood eosinophil count. This time, the eosinophil count was higher than the previous admission. A chest CT scan revealed multiple flocculent density increases in both lungs and bronchiectasis. The rapamycin-eluting stents may have caused eosinophilia and interstitial pneumonia, which improved after administering corticosteroids. A systematic review of relevant literature was conducted to summarize the characteristics of interstitial pneumonia caused by drug-eluting stents. CONCLUSION: Paclitaxel, everolimus, zotarolimus, and rapamycin are the types of drugs that can lead to drug-eluting stents, and because of the rarity of their onset, clinical doctors must be precise and prompt in diagnosing suspected cases to avoid misdiagnosis and delayed treatment.

RESUMEN

Introduction: Autoimmune cytopenias (AICs) are a group of disorders characterized by immune-mediated destruction of blood cells. In children, they are often secondary to immune dysregulation that may require long-lasting immunosuppression. Mycophenolate mofetil and sirolimus represent two well-tolerated options to treat these disorders, often as a steroid-sparing option. However, no data are available on the infection risk for patients undergoing long-lasting treatments. Patients and methods: The rate of severe infective events was calculated in episodes per 100 persons/months at risk (p/m/r) documented by the analysis of hospitalization charts between January 2015 and July 2023 of patients treated with mycophenolate mofetil or sirolimus given for isolated AIC or AICs associated with autoimmune lymphoproliferative syndrome (ALPS)/ALPS-like syndromes in two large Italian pediatric hematology units. Results: From January 2015 to July 2023, 13 out of 96 patients treated with mycophenolate mofetil or sirolimus developed 16 severe infectious events requiring hospitalization. No patients died. Overall infection rate was 0.24 person/*100 months/risk (95% CI 0.09-0.3). Serious infectious events incidence was higher in patients with ALPS-like compared to others (0.42 versus 0.09; p = 0.006) and lower in patients who underwent mycophenolate treatment alone compared to those who started sirolimus after mycophenolate failure (0.04 versus 0.29, p = 0.03). Considering only patients who started treatment at the beginning of study period, overall cumulative hazard was 18.6% at 60 months (95% CI 3.4-31.4) with higher risk of infectious events after 5 years in ALPS-like patients (26.1%; 95% CI 3.2-43.5) compared to other AICs (4%; 95% CI 0-11.4; p = 0.041). Discussion: To the best of our knowledge, this is the first study to describe the infectious risk related to mycophenolate and sirolimus chronic treatment in patients with AICs and immune dysregulation. Our data highlight that infection rate is very low and mainly related to the underlying hematological condition. Conclusions: Mycophenolate and sirolimus represent a safe immunosuppressive therapy in AICs and immune dysregulation syndromes.

RESUMEN

BACKGROUND: The efficacy and safety of each third-generation drug-eluting stent with ultrathin struts and advanced polymer technology remain unclear. We investigated the clinical outcomes of percutaneous coronary intervention using the Coroflex ISAR polymer-free sirolimus-eluting stent (SES) or Orsiro biodegradable polymer SES. METHODS: The HOST-IDEA trial (Harmonizing Optimal Strategy for Treatment of Coronary Artery Stenosis-Coronary Intervention With Next-Generation Drug-Eluting Stent Platforms and Abbreviated Dual Antiplatelet Therapy), initially designed with a 2×2 factorial approach, sought to randomize patients undergoing percutaneous coronary intervention based on dual antiplatelet therapy duration (3 versus 12 months) and stent type (Coroflex ISAR versus Orsiro). Despite randomizing 2013 patients for dual antiplatelet therapy duration, the stent arm transitioned to a registry format during the trial. Among these, 328 individuals (16.3%) were randomized for Coroflex ISAR or Orsiro SES, while 1685 (83.7%) underwent percutaneous coronary intervention without stent-type randomization. In this study, the Coroflex ISAR (n=559) and Orsiro groups (n=1449) were matched using a propensity score. The prespecified primary end point was target lesion failure, a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization at 12 months. RESULTS: The baseline patient and procedural characteristics were well balanced between the Coroflex ISAR and Orsiro groups after propensity score matching (n=559, each group). The Coroflex ISAR group was significantly associated with a higher rate of target lesion failure, mainly driven by clinically driven target lesion revascularization, compared with the Orsiro group (3.4% versus 1.1%; hazard ratio, 3.21 [95% CI, 1.28-8.05]; P=0.01). A higher risk of target lesion failure in the Coroflex ISAR group was consistently observed across various subgroups. The rates of any bleeding (hazard ratio, 0.85 [95% CI, 0.51-1.40]; P=0.52) and major bleeding (hazard ratio, 1.58 [95% CI, 0.61-4.08]; P=0.34) were comparable between the 2 groups. CONCLUSIONS: In this propensity score-matched analysis of the stent arm registry from the HOST-IDEA trial, the Orsiro SES was associated with significantly better outcomes in terms of 1-year target lesion failure, mainly driven by clinically driven target lesion revascularization, than the Coroflex ISAR SES.

RESUMEN

BACKGROUND: The BIONYX randomized trial is the first study to evaluate the Resolute Onyx durable polymer-coated zotarolimus-eluting stent (ZES) in all-comers. Furthermore, it is the first trial to assess safety and efficacy of this stent versus the Orsiro biodegradable-polymer sirolimus-eluting stent (SES) in all-comers, paying particular attention to patients with diabetes. It has previously shown promising results until 3 years of follow-up. AIMS: We aimed to assess long-term clinical outcome after percutaneous coronary intervention (PCI) with Onyx ZES versus Orsiro SES at 5-year follow-up. METHODS: The main composite endpoint was target vessel failure (TVF): cardiac death, target vessel myocardial infarction, or target vessel revascularization. Time to primary and secondary endpoints was assessed using Kaplan-Meier methods, applying the log-rank test for between-group comparison. RESULTS: Follow-up was available in 2414/2488 (97.0%) patients. After 5 years, TVF showed no significant difference between Onyx ZES and Orsiro SES (12.7% vs. 13.7%, hazard ratio [HR] 0.94, 95% confidence interval [CI] [0.75-1.17], plog-rank = 0.55). Landmark analysis between 3- and 5-year follow-up found a lower target lesion revascularization rate for Onyx ZES (1.1% vs. 2.4%, HR 0.47, 95% CI [0.24-0.93], plog-rank = 0.026). A prespecified subgroup analysis showed no significant between-stent difference in clinical outcome among patients with diabetes. After treatment with Onyx ZES, patients aged ≥75 years had significantly lower rates of TVF (13.8% vs. 21.9%, HR 0.60, 95% CI [0.39-0.93], plog-rank = 0.023). CONCLUSIONS: The final 5-year analysis of the randomized BIONYX trial showed favorable and similar long-term outcomes of safety and efficacy for Onyx ZES and Orsiro SES in both all-comers and patients with diabetes.

RESUMEN

BACKGROUND: Although lung transplantation (LTx) is the last resort for patients with end-stage lymphangioleiomyomatosis (LAM), the high waitlist mortality is a source of concern in Japan. Discontinuation of mechanistic target of rapamycin (mTOR) inhibitors prior to LTx is recommended due to the incidence of severe adverse events. Therefore, we hypothesized that mTOR inhibitors may affect the mortality of patients with LAM on the LTx waitlist. METHODS: We retrospectively compared the characteristics of consecutive patients with LAM on the LTx waitlist who were and were not receiving mTOR inhibitors. RESULTS: Twenty-nine consecutive patients with LAM who listed our center between January 2004 and December 2021 were selected from the database and enrolled in the present study. Seventeen patients (58.6%) were receiving a mTOR inhibitor, sirolimus (treatment group). During a median listing period of 1277 days, 12 patients (41.4%) were hospitalized, six patients (20.7%) died from disease before LTx, and 15 patients underwent LTx. Among the deceased patients, four patients (66.6%) had pneumothoraces. The waitlist mortality in the treatment group was significantly lower than that in the non-treatment group (p = 0.03). Among the six patients who discontinued sirolimus in the treatment group, four patients (66.6%) were hospitalized with respiratory complications after the discontinuation of sirolimus. No mTOR inhibitor-related complications arose in the treatment group undergoing LTx (n = 7), including those on a reduced sirolimus dose. CONCLUSIONS: Administration of an mTOR inhibitor until LTx may decrease waitlist mortality. Due to life-threatening events after discontinuing sirolimus pre-LTx, a reduced dose until LTx is permissible.

RESUMEN

BACKGROUND: Sirolimus-coated balloon (SCB) is a potential treatment option for peripheral arterial disease (PAD). There are currently no long-term clinical data for this novel treatment for PAD. We present the 3-year results of the first-in-human study of MagicTouch PTA SCB for treatment of PAD for both femoropopliteal and below-the-knee arteries. METHODS: The XTOSI pilot study is a prospective, single-arm, open-label, single-center trial evaluating MagicTouch PTA SCB for symptomatic PAD. Assessments through 3 years included freedom from clinically driven target lesion revascularization (CD-TLR), freedom from major amputation, amputation-free survival (AFS), overall survival, and ulcer-free status. RESULTS: At 3 years, the overall freedom from CD-TLR was 84.4%, freedom from major amputation was 86.1%, AFS was 63.3%, overall survival was 63.3%, and ulcer-free status in remaining survivors with intact limbs was 100%. For femoropopliteal lesions, at 3 years, the freedom from CD-TLR was 92.9%, freedom from major amputation was 93.3%, AFS was 70%, and overall survival was 70%. For below-the-knee lesions, at 3 years, the freedom from CD-TLR was 77.8%, freedom from major amputation was 81.0%, AFS was 58.6%, and overall survival was 58.6%. CONCLUSIONS: SCB in the XTOSI pilot study showed promising clinical results sustained to 3 years, and no long-term safety concerns were raised. Randomized trials are currently ongoing to investigate the safety and efficacy of SCB for treatment of PAD.

RESUMEN

Systemic mastocytosis (SM) corresponds to a rare and heterogeneous spectrum of diseases characterized by the accumulation of atypical mast cells (MCs). Advanced mastocytosis (Adv-SM) is associated with poor survival; in contrast, patients with non-advanced SM (non-Adv-SM) usually have a normal life expectancy but may experience poor quality of life. Despite recent therapeutic progress including tyrosine kinase inhibitors, new treatment options are needed for refractory and/or intolerant patients with both severely symptomatic and Adv-SM. In vitro, the mTOR pathway is activated in MCs from patients bearing the KIT D816V mutation. Furthermore, rapamycin induces the apoptosis of KIT D816V MCs selectively. In this nationwide study, we report the outcomes of patients diagnosed with SM and treated with a mammalian target of rapamycin inhibitor (imTOR) within the French National Reference Center for mastocytosis (CEREMAST). All patients registered were relapsing, treatment-refractory, or ineligible for other cytoreductive therapy. Non-Adv-SM patients received imTOR as a monotherapy (rapamycin/everolimus), and Adv-SM patients received imTOR as a monotherapy or in combination with cytarabine. The objective response rate (ORR) in non-Adv-SM was 60% (partial response in 40% and major response in 20%), including reductions in skin involvement, mediator release symptoms, and serum tryptase. In the Adv-SM group, the ORR was 20% (including one major response and one partial response, both in patients with a KIT D816V mutation), which enabled a successful bridge to allogeneic stem cell transplantation in one patient. Our results suggest that imTOR treatment has potential benefits in patients with SM harboring a KIT D816V mutation.

RESUMEN

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.nab-Sirolimus is approved in the United States for the treatment of metastatic or locally advanced malignant perivascular epithelioid cell tumor (PEComa) on the basis of the primary analysis results of the phase II Advanced Malignant Perivascular Epithelioid Cell Tumors (AMPECT) trial (ClinicalTrials.gov identifier: NCT02494570). Results from the primary analysis were previously published; however, the median duration of response (mDOR) had not been reached at that time. Here, 3 years after the primary analysis, we report final efficacy and safety data (data cutoff: April 29, 2022). At study completion, the confirmed overall response rate (by independent radiologist review using RECIST v1.1) was 38.7% (95% CI, 21.8 to 57.8), with an additional converted confirmed complete response (n = 2). Median progression-free survival remained the same at 10.6 months (95% CI, 5.5 to 41.2). The mDOR was reached at 39.7 months (95% CI, 6.5 to not reached [NR]), and the median overall survival at completion was 53.1 months (95% CI, 22.2 to NR). The most common treatment-related adverse events (TRAEs) were stomatitis (82.4%) and fatigue and rash (each 61.8%). No new or unexpected adverse events occurred, and no grade ≥4 TRAEs were reported.

RESUMEN

BACKGROUND: Intravenous leiomyomatosis (IVL), pulmonary benign metastatic leiomyomatosis (PBML), and leiomyomatosis peritonealis disseminata (LPD) are leiomyomas with special growth patterns and high postoperative recurrence rates. We report the safety and efficacy of a pilot study of sirolimus in the treatment of recurrent IVL, PBML, and recurrent LPD. METHODS: This was a pilot study to evaluate the safety and efficacy of sirolimus in the treatment of leiomyomatosis (ClinicalTrials.gov identifier NCT03500367) conducted in China. Patients received oral sirolimus 2 mg once a day for a maximum of 60 months or until disease progression, intolerable toxicity, withdrawal of consent, or investigator decision to stop. The primary end point of this study was the objective response rate. Secondary end points included safety and tolerability, disease control rate, and progression-free survival. RESULTS: A total of 15 patients with leiomyomatosis were included in the study, including five with recurrent IVL, eight with PBML and two with recurrent LPD. The median follow-up time was 15 months (range 6-54 months), nine patients (60%) had treatment-related adverse events (including all levels), and two patients had treatment-related grade 3 or 4 adverse events. The objective response rate was 20.0% (95% CI, 7.1-45.2%), and the disease control rate was 86.7% (95% CI, 62.1-96.3%). Partial response was achieved in three patients. The median response time in the three partial response patients was 33 months (range 29-36 months), and the sustained remission time of these three patients reached 0, 18, and 25 months, respectively. CONCLUSIONS: Sirolimus was safe and effective in the treatment of recurrent IVL, PBML, and recurrent LPD. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03500367. Registered on 18 April 2018.

RESUMEN

BACKGROUND: The outcomes of percutaneous coronary intervention (PCI) in diabetic patients are still suboptimal, and it is unclear if diabetic patients might derive a benefit from the use of drug-coated balloons. AIMS: To evaluate the impact of diabetes mellitus on the outcomes of patients undergoing PCI with sirolimus-coated balloon (SCB) MagicTouch (Concept Medical, India). METHODS: We conducted a subgroup analysis of the prospective, multicenter, investigator-initiated EASTBOURNE registry, evaluating the performance of MagicTouch SCB in patients with and without diabetes. The study primary endpoint was target lesion revascularization (TLR) at 12-month follow-up. Secondary clinical endpoints were major adverse clinical events (MACE), death, myocardial infarction (MI), and BARC 2-5 bleedings. RESULTS: Among 2,083 enrolled patients, a total of 864 suffered from diabetes (41.5%). Patients with diabetes had a numerically higher occurrence of TLR (6.5% vs. 4.7% HR 1.38, 95%CI 0.91-2.08), all-cause death (3.8% vs. 2.6%, HR 1.81, 95%CI 0.95-3.46), and MACE (12.2% vs. 8.9%; HR 1.26 95%CI 0.92-1.74). The incidence of spontaneous MI was significantly higher among diabetic patients (3.4% vs. 1.5%, HR 2.15 95%CI 1.09-4.25); bleeding events did not significantly differ. The overall incidence of TLR was higher among in-stent restenosis (ISR) as compared to de-novo coronary lesions, irrespectively from diabetes status. CONCLUSIONS: In the EASTBOURNE DIABETES registry, diabetic patients treated with the MagicTouch SCB did not have a significant increase in TLR when compared to non-diabetic patients; moreover, diabetic status did not affect the study device performance in terms of TLR, in both de-novo lesions and ISR.

RESUMEN

OBJECTIVE: The efficacy of sirolimus in treating severe or refractory systemic lupus erythematosus (SLE) has been confirmed by small-scale clinical trials. However, few studies focused on mild or moderate SLE. Therefore, in this study we elucidated clinical efficacy of add-on sirolimus in patients with mild or moderate SLE. METHODS: Data of 17 consecutive patients with SLE were retrospectively collected. SLE Disease Activity Index-2000 (SLEDAI-2K), clinical manifestation, laboratory data and peripheral T lymphocyte subsets with cytokines were collected before and 6 months after sirolimus add-on treatment. T cell subsets were detected by flow cytometry and cytokines were determined by multiplex bead-based flow fluorescent immunoassay simultaneously. Twenty healthy controls matched with age and sex were also included in our study. RESULTS: (1) The numbers of peripheral blood lymphocytes, T cells, T helper (Th) cells, regulatory T (Treg) cells, Th1 cells, Th2 cells and Treg/Th17 ratios in patients with SLE were significantly lower, while the numbers of Th17 cells were evidently higher than those of healthy control (p<0.05). (2) After 6 months of sirolimus add-on treatment, urinary protein, pancytopenia, immunological indicators and SLEDAI-2K in patients with SLE were distinctively improved compared with those before sirolimus treatment (p<0.05). (3) The numbers of peripheral blood lymphocytes, T cells, Th cells, Treg cells, Th2 cells and the ratios of Treg/Th17 in patients with SLE after treatment were clearly higher than those before (p<0.05). (4) The levels of plasma interleukin (IL)-5, IL-6 and IL-10 in patients with SLE decreased notably, conversely the IL-4 levels increased remarkably compared with pretreatment (p<0.05). CONCLUSIONS: (1) Patients with SLE presented imbalanced T cell subsets, especially the decreased ratio of Treg/Th17. (2) Sirolimus add-on treatment ameliorated clinical involvement, serological abnormalities and disease activity without adverse reactions in patients with SLE. (3) The multi-target therapy facilitates the enhanced numbers of Treg cells, Treg/Th17 imbalance and anti-inflammatory cytokines, simultaneously, reducing inflammatory cytokines.

RESUMEN

BACKGROUND: Studies evaluating the safety and efficacy of drug coating balloons (DCB) for the treatment of lesions in large coronary vessel are limited. AIMS: Our study aimed to evaluate the performance of a sirolimus DCB in large coronary arteries. METHODS: We analyzed all the procedures included in the EASTBOURNE Registry (NCT03085823) enrolling patients with a clinical indication to percutaneous coronary intervention performed by a sirolimus DCB according to investigator judgment. In the present analysis, a cut-off of 2.75 mm was used to define large coronary arteries. Primary endpoint of the study was clinically driven target lesion revascularization (TLR) at 24 months whereas secondary endpoint included procedural success, myocardial infarction (MI), cardiac death and total mortality. RESULTS: Among the 2123 patients and 2440 lesions enrolled in the EASTBOURNE study between 2016 and 2020, 757 patients/810 lesions fulfilled the criteria for the present analysis. Mean reference vessel diameter was 3.2 ± 0.3 mm with mean lesion length of 22 ± 7 mm. Procedural success was high (96%) and at 2-year follow up the device showed a good efficacy with a TLR rate of 9%. There were 34 deaths (4.5%), 30 MIs (4%) and 8 BARC type 3-5 bleedings (1.1%). In-stent restenosis (629 lesions) and de novo lesions (181) were associated with 11% and 4% rates of TLR at 2 years, respectively (p = 0.003). CONCLUSIONS: Clinical performance of a sirolimus DCB in large coronary artery vessels shows promising signals at 2-year follow up, both in de novo and in-stent restenosis lesions.

RESUMEN

OBJECTIVES: The management of vascular malformations is complex and challenging. This study aimed to explore efficacy, plasma trough concentrations of sirolimus, post-withdrawal conditions, and adverse reactions of sirolimus in treating complex vascular malformations. METHODS: In our center, we analyzed vascular malformations treated with sirolimus (and corticosteroid) from August 2017 to June 2021. Meanwhile, we reviewed the medical records, the efficacy, side effects, and laboratory tests. Patients who had stopped taking sirolimus were followed up by telephone. RESULTS: A total of 25 patients with complicated vascular malformations in our center, including 7 females and 18 males aged 4 months to 15 years, were enrolled. In all, 19 patients (76.0%) responded to sirolimus, and the plasma concentration of sirolimus fluctuated between 0.97 and 27.15 ng/ml. In all, 24 patients (96.0%) were in follow-up. A total of 15 patients (62.5%) stopped taking sirolimus during follow-up, and 2 patients (13.3%) discontinued the sirolimus due to side effects. A total of 3 patients (20.0%) restarted sirolimus treatment. CONCLUSION: Starting dose of 1.5-2 mg/m2 sirolimus is effective and safe in vascular malformation treatment. The best treatment regimen and discontinuation indications needed more investigation. Most should be done about targeted therapy to improve effectiveness and reduce side effects.
