ABSTRACT: Purpose
Drug-coated devices have been widely accepted as one of the most promising therapies for femoropopliteal artery revascularization. A recent meta-analysis showed increased mortality in patients treated with drug-coated devices. We sought to examine the association between mortality and drug-coated devices after the treatment of the femoropopliteal artery based on the Korea national administrative claims data.Methods
In the National Health Insurance Service database from August 2015 to December 2017, we identified patients with femoropopliteal artery revascularization using percutaneous transluminal angioplasty (PTA), bare metal stents (BMS), drug-coated balloon (DCB), or drug-eluting stents (DES). Kaplan-Meier methods were used to estimate the survival among devices, and log-rank tests were used to evaluate differences between groups. Adjusted hazard ratios (aHRs) were computed using the inverse probability of treatment weightings (IPTW).Results
There were 1,724 patients (mean age, 70.9 ± period was 552 days (interquartile range, 404-688 days). There was a difference in IPTW-adjusted mortality risk among device types (26.3% in PTA, 22.1% in BMS, 17.7% in DCB, and 17.8% in DES; P = 0.004). IPTW-adjusted Cox nproportional hazard analysis showed that drug-coated devices were associated with decreased all-cause mortality risk (aHR, 0.70; 95% confidence interval, 0.58-0.86).Conclusion
Our real-world analysis showed that there was no evidence of increased all-cause mortality after femoropopliteal artery revascularization with drug-coated devices compared with non-drug-coated devices.

Project description:ImportanceIn a recent meta-analysis of randomized clinical trials, femoropopliteal artery revascularization with paclitaxel drug-coated devices was associated with increased long-term all-cause mortality compared with non-drug-coated devices. However, to our knowledge, these findings have not been replicated in other data sources and may be subject to confounding from missing data associated with patient withdrawal and loss to follow-up.ObjectiveTo evaluate differences in all-cause mortality between patients who were treated with drug-coated devices vs non-drug-coated devices for femoropopliteal artery revascularization.Design, setting, and participantsThis nationwide, multicenter retrospective cohort study included 16 560 Centers for Medicare and Medicaid Services beneficiaries who were admitted for femoropopliteal artery revascularization from January 1, 2016, to December 31, 2016. All-cause mortality was analyzed through September 30, 2017.ExposuresDrug-coated devices (drug-eluting stent [DES] or drug-coated balloon [DCB]) compared with non-drug-coated devices (bare metal stent or uncoated percutaneous transluminal angioplasty balloon).Main outcomes and measuresThe primary outcome was all-cause mortality analyzed through the end of follow-up.ResultsAmong 16 560 patients treated at 1883 hospitals, the mean (SD) age was 72.9 (11) years, 7734 (46.7%) were men, 12 232 (73.9%) were white, 8222 (49.7%) currently or had previously used tobacco, 9817 (59.3%) had diabetes, and 8450 (51.0%) had critical limb ischemia (CLI). Drug-coated devices were used in 5989 participants (36.2%). The median follow-up was 389 days (interquartile range, 277-508 days). Among all patients, treatment with drug-coated devices was associated with a lower cumulative incidence of all-cause mortality compared with treatment with non-drug-coated devices through 600 days postprocedure (32.5% vs 34.3%, respectively; log-rank P = .007). Similar survival trends were observed when treatment was stratified by using a DCB alone or DES with or without DCB. After multivariable adjustment, drug-coated devices were not associated with a difference in all-cause mortality compared with non-drug-coated devices (hazard ratio [HR], 0.97; 95% CI, 0.91-1.04; P = .43). These findings were consistent among those with CLI (HR, 0.93; 95% CI, 0.85-1.01; P = .09) or without CLI (HR, 0.94; 95% CI, 0.85-1.03; P = .20), and for those treated with DCB alone (HR, 0.94; 95% CI, 0.86-1.03; P = .17) or DES with or without DCB (HR, 0.97; 95% CI, 0.89-1.06; P = .48).Conclusions and relevanceIn this large nationwide analysis of Centers for Medicare and Medicaid Services beneficiaries, there was no evidence of increased all-cause mortality following femoropopliteal artery revascularization with drug-coated devices compared with non-drug-coated devices.

Project description:ObjectiveTo evaluate the long-term outcomes after drug-coated balloon (DCB) angioplasty dissection in patients with complex femoropopliteal artery disease.MethodsTwo hundred patients with femoropopliteal peripheral artery disease were enrolled in the AcoArt I trial and randomly assigned to either the DCB or percutaneous transluminal angioplasty (PTA) group. A total of 86 patients with post-balloon angioplasty dissection were reanalyzed. The primary endpoint was clinically driven target lesion revascularization (CD-TLR) over five years. Kaplan-Meier curve estimates were used to evaluate the association between the treatment and CD-TLR. Interaction and stratified analyses were also performed.ResultsOver five years, patients treated with DCB angioplasty demonstrated an acceptable effect with a numerically higher but not statistically significant rate of freedom from CD-TLR compared with those treated by PTA (Kaplan-Meier estimate of 77.6% vs 64.4%; log-rank P = 0.08). Among the patients who underwent TLR, the mean time from intervention to TLR in the DCB group was significantly prolonged compared to the PTA group (P < 0.001). The stratified analysis showed that the Rutherford classification played an interactive role in the association between the DCB angioplasty and low CD-TLR rate at five years. No significant difference in the all-cause mortality was found in the patients with post-balloon angioplasty dissection between the two treatment groups.ConclusionThe five-year follow-up outcomes of the post-balloon angioplasty dissection in the AcoArt I trial demonstrated that DCB angioplasty is more trustworthy than PTA, with a higher rate of freedom than CD-TLR and sustained improvement in clinical symptoms. However, the all-cause mortality rate in patients with femoropopliteal lesions is similar after both DCB angioplasty and PTA.Clinical trial registrationhttp://www.clinicaltrials.gov.Unique identifierNCT01850056.

Project description:BackgroundPaclitaxel-containing devices (PTXDs) significantly reduce reintervention in patients with symptomatic femoropopliteal peripheral artery disease. A recent aggregate-data meta-analysis reported increased late mortality in patients with peripheral artery disease treated with PTXDs. We performed an individual patient data meta-analysis to evaluate mortality.MethodsManufacturers of US Food and Drug Administration-approved and commercially available devices in the United States provided deidentified individual patient data for independent analysis. Cox proportional hazards 1-stage meta-analysis models using intention-to-treat methods were used for the primary analysis. A secondary analysis of recovered missing vital status data was performed. The impact of control crossover to PTXDs, cause-specific mortality, and drug dose mortality were assessed.ResultsA total of 2185 subjects and 386 deaths from 8 PTXD trials with 4-year median follow-up were identified. The primary analysis indicated a 38% (95% CI, 6% to 80%) increased relative mortality risk, corresponding to 4.6% absolute increase, at 5 years associated with PTXD use. Control and treatment arm loss to follow-up and withdrawal were 24% and 23%, respectively. With inclusion of recovered vital status data, the excess relative mortality risk was 27% (95% CI, 3%-58%). This observation was consistent across various scenarios, including as-treated analyses, with no evidence of increased risk over time with PTXDs. Mortality risk tended to be increased for all major causes of death. There were no subgroup differences. No drug dose-mortality association was identified.ConclusionsThis individual patient data meta-analysis, based on the most complete available data set of mortality events from PTXD randomized controlled trials, identified an absolute 4.6% increased mortality risk associated with PTXD use.

Project description:PURPOSE:The post-hoc multivariable analysis of EffPac study data aimed to identify explanatory variables for efficacy of femoropopliteal artery angioplasty. METHODS:In the prospective, randomized, controlled EffPac study, patients were allocated to either DCB or plain old balloon angioplasty. Multivariable regression including interaction analysis was conducted to assess the impact of selected variables on the outcome measures of late lumen loss (LLL) at 6 months, and on binary restenosis, target lesion revascularization (TLR), clinical improvement, and hemodynamic improvement at 12 months. RESULTS:A total of 171 patients (69?±?8 years, 111 men) were treated at 11 German centers. Hypertension increased, and advanced age decreased LLL (B coefficient [B]: 0.7 [95% CI -?0.04 to 1.3], p?=?0.06 and -?0.3 per 10 years [95% CI -?0.5 to 0.01], p?=?0.06, respectively). DCB angioplasty decreased odds of 12-month TLR and binary restenosis (OR 0.4 [95% CI 0.2 to 0.8], p?=?0.01 and OR 0.1 [95% CI 0.01 to 0.6], p?=?0.02, respectively). Lesion length and severe calcification decreased clinical improvement (B: -?0.1 per 10 mm [95% CI -?0.1 to -?0.03], p?=?0.001 and -?0.1 [95% CI -?1.7 to -?0.1], p?=?0.03, respectively). DCB angioplasty in former smokers improved ABI (0.2 [95% CI 0.01 to 0.5], p?=?0.04). CONCLUSION:DCB angioplasty decreased the incidence of 12-month restenosis and TLR. Increasing lesion length and severe calcification reduced clinical improvement. Hypertension is suspected to facilitate, and advanced age to mitigate LLL. DCB improved ABI most in former smokers.

Project description:BackgroundThe connection between paclitaxel-coated devices (PCD) use during peripheral vascular interventions (PVI) and mortality is debated. We aimed to analyze patterns of PCD use and the safety and effectiveness of PCD use in the superficial femoral and/or popliteal arteries.MethodsPatients undergoing PVI of femoropopliteal lesions with and without PCD between January 1, 2015 and June 30, 2017 were compared using the American College of Cardiology's National Cardiovascular Data Registry PVI Registry. Outcomes were derived from Centers for Medicare & Medicaid claims data. The primary outcome was all-cause mortality at 6-, 12-, and 24-months following PVI. Inverse probability weighting and frailty models were used to assess the differences between groups. The analysis was IRB-approved.ResultsIn the overall cohort consisting of 6,302 femoropopliteal PVIs, PCD-PVI patients were more likely to be treated for claudication (63.5% vs 51.3%, P< .001), less likely to have a chronic total occlusion (24.6% vs 34.7%, P < .001), and more likely to be treated in certain geographic and practice settings. In the analytic cohort consisting of 1,666 femoropopliteal PVIs with linked claims outcomes (888 PCD-PVI, 53.3%), unadjusted rates of all outcomes were lower in PCD-PVI patients. After adjustment, there were no significant differences in mortality following PCD-PVI versus non-PCD PVI at 1 year (adjusted RR 0.78, 95% CI 0.60-1.01, P= .055) or 2 years (aRR 0.98, 95% CI 0.77-1.24, P= .844).ConclusionThere were significant differences between the patients in whom and settings in which PCD-PVI was versus was not used. PCD-PVI was not associated with an increased risk of 2-year mortality in real-world use.

Project description:ImportancePaclitaxel-coated peripheral devices have been associated with increased mortality, yet this harm signal has not been replicated outside of meta-analyses of small trials.ObjectiveTo provide a longitudinal assessment of the safety of femoropopliteal endovascular treatment with peripheral drug-coated devices (DCDs) among Medicare beneficiaries.Design, setting, and participantsSAFE-PAD (Safety Assessment of Femoropopliteal Endovascular Treatment With Paclitaxel-Coated Devices) was a retrospective cohort study designed with the US Food and Drug Administration to evaluate the noninferiority of mortality between DCDs and non-drug-coated devices (NDCDs) for femoropopliteal revascularization performed in 2978 inpatient and outpatient facilities in the US from April 1, 2015, through December 31, 2018. Evaluation of the primary outcome was assessed through May 31, 2020. Participants were Medicare fee-for-service beneficiaries 66 years and older with 1 or more years of enrollment prior to femoropopliteal revascularization. Prespecified subgroups included low-risk cohorts, procedure location, disease severity, and device type. Inverse probability weighting was used to account for imbalances of observed characteristics. Sensitivity analyses were used to evaluate the potential influence of unmeasured confounding.ExposuresTreatment with DCDs vs NDCDs as determined by claims codes during the index procedure.Main outcomes and measuresThe primary outcome was all-cause mortality. Secondary outcomes included repeated hospitalization, repeated lower extremity revascularization, and lower extremity amputation. Falsification end points were acute myocardial infarction, congestive heart failure, and pneumonia.ResultsOf 168 553 patients, 70 584 (41.9%) were treated with a DCD. The mean (SD) age was 77.0 (7.6) years, 75 744 (44.9%) were female, 136 916 of 167 197 (81.9%) were White individuals, 85 880 of 168 553 (51.0%) had diabetes, 82 554 of 168 553 (49.0%) used tobacco, 78 665 of 168 553 (45.7%) had critical limb ischemia (CLI), and 13 296 of 168 553 (7.9%) had a prior amputation. Median follow-up was 2.72 years (interquartile range, 0.87-3.77; longest, 5.16 years). After weighting, the cumulative incidence of all-cause mortality was 53.8% with DCDs and 55.1% with NDCDs (hazard ratio [HR], 0.95; 95% CI, 0.94-0.97; noninferiority P < .001). Cox regression and instrumental variable analyses were consistent with the primary findings. No harm associated with DCDs was observed among subgroups, including those treated with stents (HR, 0.97; 95% CI, 0.95-1.00) or balloons (HR, 0.94; 95% CI, 0.92-0.96), with or without CLI (CLI: HR, 0.95; 95% CI, 0.93-0.97; non-CLI: HR, 0.97; 95% CI, 0.95-0.99), and those within the lowest quartile of total comorbidities (HR, 0.95; 95% CI, 0.92-0.99).Conclusions and relevanceIn this initial report from the SAFE-PAD cohort study, DCDs were found to be noninferior to NCDCs in respect to mortality through a median follow-up of 2.72 years. This finding remained robust in sensitivity analyses and was consistent across prespecified subgroups.

Project description:Purpose: To report the 36-month outcomes from the prospective, multicenter, single-arm IN.PACT Global Study (ClinicalTrials.gov identifier NCT01609296) evaluating the performance of the IN.PACT Admiral drug-coated balloon (DCB) in real-world patients with femoropopliteal occlusive disease. Materials and Methods: The IN.PACT Global Study was conducted at 64 international sites and enrolled 1535 patients with complex lesions, which included bilateral disease, multiple lesions, de novo in-stent restenosis, long lesions, and chronic total occlusions. The predefined full clinical cohort included 1406 patients (mean age 68.6 years; 67.8% men) with claudication or rest pain treated with the study DCB. Mean lesion length was 12.09±9.54 cm; 18.0% had in-stent restenosis, 35.5% were totally occluded, and 68.7% were calcified. Freedom from clinically-driven target lesion revascularization (CD-TLR) was evaluated through 36 months. The safety composite endpoint was freedom from device- and procedure-related death through 30 days and freedom from major target limb amputation and clinically-driven target vessel revascularization within 36 months. All safety and revascularization events were reviewed by an independent clinical events committee. Results: The Kaplan-Meier estimate of freedom from CD-TLR through 36 months was 76.9%. The composite safety endpoint was achieved in 75.6% of patients. The 36-month all-cause mortality rate was 11.6%, and the major target limb amputation rate was 1.0%. The Kaplan-Meier estimate of freedom from CD-TLR through 36 months was significantly lower in patients with chronic limb-threatening ischemia (CLTI) compared with claudicants (67.6% vs 78.0%; p=0.003). Lesions affecting both the superficial femoral artery (SFA) and popliteal artery had lower Kaplan-Meier freedom from CD-TLR through 36 months (69.2%) than either isolated SFA (79.7%) or popliteal artery lesions (76.5%; log- rank p<0.001). Predictors of CD-TLR through 36 months included increased lesion length, reference vessel diameter ?4.5 mm, in-stent restenosis, bilateral disease, CLTI, and hyperlipidemia. Conclusion: DCB angioplasty with the IN.PACT Admiral DCB for femoropopliteal disease in a diverse and complex real-world population is associated with sustained clinical efficacy and low rates of reinterventions at 3 years after the initial procedure.

Project description:BackgroundMeta-analyses of randomised trials of paclitaxel-coated peripheral devices found an association with worse long-term survival.AimsWe aimed to assess long-term mortality in patients treated with drug-coated versus non-drug-coated devices who are insured by Medicare Advantage (MA), an alternative to traditional Medicare that represents >30% of the Medicare eligible population. We analysed data from an MA administrative claims data source that includes both inpatient and outpatient femoropopliteal artery revascularisation procedures.MethodsPatients treated with or without drug-coated devices for femoropopliteal artery revascularisation from 4/2015-12/2017 were studied using Optum's De-identified Clinformatics Datamart Database. Mortality was assessed up to December 2019 using Kaplan-Meier cumulative mortality curves and Cox proportional hazard models. Inverse probability of treatment weighting was used to adjust for differences between groups.ResultsOf 16,796 patients revascularised, 4,427 (26.4%) were treated with drug-coated devices: 3,600 (81.3%) balloons and 827 (18.7%) stents. The median follow-up was 2.66 years (IQR 2.02-3.52). Treatment with drug-coated devices was associated with similar long-term mortality to non-drug-coated devices (adjusted HR 1.03, 95% CI: 0.96-1.10; p=0.39). Results were comparable for patients treated with balloons alone (adjusted HR 1.00, 95% CI: 0.92-1.08; p=0.96) or stents (adjusted HR 1.02, 95% CI: 0.88-1.18; p=0.78). These findings did not differ based on treatment setting, disease severity, age, sex or comorbidity burden (interaction p>0.05 for all).ConclusionsIn this large cohort, there was no evidence of increased long-term mortality following treatment with drug-coated devices.

Project description:To estimate the clinical and economic impact of drug-eluting endovascular treatment strategies for femoropopliteal artery disease compared with current standard of care.Systematic literature search to pool target lesion revascularisations (TLR). Model-based per-patient cost impact and quasi-cost-effectiveness projection over 24 months based on pooled TLRs and current reimbursement.The UK's National Health Service (NHS).Patients presenting with symptomatic femoropopliteal disease eligible for endovascular treatment.Current National Institute for Health and Care Excellence (NICE) guideline-recommended treatment with percutaneous transluminal balloon angioplasty (PTA) and bailout bare metal stenting (BMS) versus primary BMS placement, or drug-coated balloon (DCB), or drug-eluting stent (DES) treatment.24-month per-patient cost impact to NHS (primary outcome).pooled 24-month TLR rates; numbers needed to treat (NNTs); cost per TLR avoided and estimated incremental cost-effectiveness ratio (ICER) in £ per quality-adjusted life year (QALY).N=28 studies were identified, reporting on 5167 femoropopliteal lesions. Over 24 months, DCB, DES and BMS reduced TLRs of de novo lesions from 36.2% to 17.6%, 19.4% and 26.9%, respectively, at an increased cost of £43, £44 and £112. NNTs to avoid 1 TLR in 24 months were 5.4, 6.0 and 10.8, resulting in cost per TLR avoided of £231, £264 and £1204. DCB was estimated to add 0.011 QALYs, DES 0.010 QALYs and BMS 0.005 QALYs, resulting in estimated ICERs of £3983, £4534 and £20 719 per QALY gained. A subset analysis revealed more favourable clinical and economic outcomes for a 3.5 µg/mm(2) DCB with urea excipient, compared with the rest of DCBs. A modest reduction of 10% in DCB and DES prices made drug-eluting treatments dominant.Widespread adoption of drug-eluting endovascular therapies for femoropopliteal disease would add meaningful clinical benefit at reasonable additional costs to the NHS. Based on currently available data, DCBs offer the highest clinical and economic value.
