Introduction

Adalimumab (ADA) is a medication used in the treatment of several autoimmune diseases. Despite the beneficial effects of ADA, its adherence and persistence rates are low. Patients treated with ADA from Clalit Health Services (CHS) can enroll in AbbVie’s patient support program (PSP), which aims to improve ADA adherence and persistence. Therefore, we examine whether PSP participation is associated with a longer persistence and/or an improved adherence to ADA.

Methods

A real-world retrospective cohort study of all new ADA users from CHS, comparing those enrolled in the offered PSP to those not enrolled. The data regarding PSP users can be tracked using CHS’s data warehouse. The index date was defined as the date of the patients’ first purchase of ADA occurring between August 1, 2012 and December 31, 2014. The follow-up data were collected at 12, 24, and 36 months. Persistence was assessed using survival analyses of time until discontinuation, and adherence was assessed using medication possession ratio (MPR).

Results

There were 1520 patients in the study, 755 (49.7%) of whom were PSP users. PSP users were 54.3% female vs. 51.9% among non-PSP users (p?=?0.355) and they were significantly younger than non-PSP users (mean age 42.3 vs. 45.0 years, p?=?0.002) The PSP and non-PSP users’ persistence was 673 and 574 days, respectively (p?<?0.001). Further, the PSP users were more likely than the non-PSP users to be persistently taking medication at the 12-month follow-up (57.5% vs. 45.6%, p?<?0.001). The 12-month mean adherence rate among those with at least 12 months of persistence was significantly improved for the PSP users compared to the non-PSP users (94.1% vs. 92.9%, p?=?0.026).

Conclusion

The AbbVie PSP provided to CHS patients was associated with a longer persistence among new users of ADA. It was also associated with significantly higher adherence rate within the first 12 months.

Purpose

Methotrexate (MTX) and adalimumab are well-recognized treatments of rheumatoid arthritis (RA), the efficacy of which may be driven by intracellular polyglutamates (PGs). The aim of this analysis was to characterize MTX PG concentrations and adalimumab pharmacokinetics in the CONCERTO trial. In addition, the relationships between MTX dose/pharmacokinetics, adalimumab pharmacokinetics, and efficacy were evaluated.

Methods

CONCERTO was a double-blind, parallel-arm study in patients with early RA randomized to adalimumab 40 mg SC every other week plus blinded MTX 2.5, 5, 10, or 20 mg PO once weekly, for 26 weeks. Blood samples were obtained through week 26 for the determination of concentrations of MTX PG, adalimumab, and anti-adalimumab antibody (AAA). Clinical outcomes were also assessed.

Findings

A total of 395 patients were included in the analysis (MTX, 329; adalimumab, 395). The mean time to steady-state MTX PG concentration was increased with MTX dose, from 8 to >26 weeks, depending on PG chain length. Dose proportionality changed with PG chain length. As MTX dose was increased, the percentage of short-chain PGs increased less than dose proportionally, while the percentage of long-chain PGs increased more than dose proportionally. For very-long-chain PGs, dose proportionality could not be assessed due to the nonmeasurable concentrations in the 2.5- and 5-mg MTX dose groups. As MTX dose increased, mean adalimumab concentrations also increased (P < 0.001). The percentage of patients with AAA decreased with increasing MTX dose, and at week 26, AAA+ status was significantly correlated with MTX dose level (P = 0.005). In general, rates of response, defined using the 28-joint count disease activity score based on C-reactive protein (DAS28[CRP]; response, <3.2), were greater in the subgroup without AAA. The likelihood of a patient achieving a DAS28(CRP) response was related to the baseline measurement (P < 0.001) and to the concentration of adalimumab (P = 0.001), but not to the MTX regimen (P = 0.689).

Implications

The dose–response characteristics of MTX PG pharmacokinetics and the resultant effects of MTX on adalimumab exposures should be considered when determining the benefit–risk profile of MTX and adalimumab combination therapy in patients with early RA.

Purpose

This observational study of oncologic clinical practices was designed to describe real-world patterns of use of emerging therapies (abiraterone acetate, cabazitaxel, enzalutamide, radium-223, sipuleucel-T) in patients with castration-resistant prostate cancer and to characterize their concomitant use with denosumab or zoledronic acid.

Methods

A retrospective cohort study was conducted using a database of electronic health records from oncology practices across the United States. Eligible patients had a diagnosis of prostate cancer (International Classification of Diseases, Ninth Revision [ICD-9] code 185/International Classification of Diseases, Tenth Revision [ICD-10] code C61) before or concurrent with a visit between January 1, 2013, and December 31, 2015; follow-up was performed through June 30, 2016. From this population, we identified those who received an emerging therapy and a subset who also received denosumab or zoledronic acid.

Findings

A total of 71,606 men met the eligibility criteria, and 5131 (7%) received emerging therapy. In the emerging therapy cohort (at the time of the first use), median age was 75 years, median prostate-specific antigen value was 22.7 ng/mL, 56% had bone metastases, and 80% were docetaxel naive. Abiraterone and enzalutamide were the most commonly used first emerging therapies (52% and 31%, respectively), followed by sipuleucel-T (9%), cabazitaxel (5%), and radium-223 (1.5%). Of the emerging therapy cohort, 3121 patients (61%) received concomitant denosumab (70%) or zoledronic acid (35%); 5% received both.

Implications

Among patients with prostate cancer treated in the United States, most of those treated with an emerging therapy between 2013 and 2015 also received denosumab or zoledronic acid, suggesting that the concomitant use of these therapy types is currently a common practice. Use of denosumab or zoledronic acid was higher in patients with verified bone metastases.  相似文献

Purpose

Acute myeloid leukemia (AML) disproportionately affects older adults; the prognosis in this subpopulation is generally poor, with variable use of inpatient chemotherapy. This study characterizes treatment patterns, hospitalizations, and outcomes among older patients with AML.

Methods

Using the Centers for Medicare & Medicaid Services' 2010–2012 100% Limited Data Set (LDS), data from all hospital claims from fee-for-service Medicare beneficiaries between 60 and 75 years of age with newly diagnosed AML and ≥1 hospitalization were analyzed.

Findings

Among 3700 identified patients with AML, 1979 (53.5%) received chemotherapy. Hospitalization rates were highest initially and then declined over time, irrespective of chemotherapy use. The mean length of initial hospital stay was longer in patients receiving chemotherapy. Intensive care unit admissions occurred in 33% of initial hospitalizations. Factors associated with receiving chemotherapy included younger age, fewer comorbidities, and the absence of prior hematologic disorders. Chemotherapy was associated with significantly increased survival compared with no chemotherapy (P < 0.0001).

Implications

AML in older patients is associated with frequent hospitalizations and intensive care unit admissions. New treatment options with more favorable risk-to-benefit profiles are needed in this population.  相似文献

Purpose

Meropenem/vaborbactam is a novel intravenous antibiotic combining the carbapenem, meropenem, with a novel β-lactamase inhibitor, vaborbactam. Meropenem/vaborbactam is administered as a 3-hour infusion given every 8 hours, thereby potentially restricting an intravenous line for 9 h/d. Intravenous medications may be given concurrently via Y-site when compatibility data are available. Herein, physical compatibility was determined for the identification which medications can be coadministered with meropenem/vaborbactam via Y-site.

Methods

Y-site administration was simulated in vitro by admixing 5 mL of meropenem 8 mg/mL and vaborbactam 8 mg/mL with an equal volume of 88 other diluted intravenous medications, including 34 antimicrobials. All other medications were diluted with 0.9% sodium chloride to the upper range of concentrations considered standard for intravenous infusion. Visual inspection, turbidity measurement, and pH measurement were performed prior to admixture, directly after admixture, and at time points up to 3 hours after admixture.

Findings

Of the 88 medications tested, meropenem/vaborbactam was compatible with 73 (83%), including many antibiotics such as aminoglycosides (amikacin, gentamicin, and tobramycin), colistin, fosfomycin, linezolid, tedizolid, tigecycline, and vancomycin. Physical incompatibility was observed with albumin, amiodarone, anidulafungin, calcium chloride, caspofungin, ceftaroline, ciprofloxacin, daptomycin, diphenhydramine, dobutamine, isavuconazole, midazolam, nicardipine, ondansetron, and phenytoin.

Implications

The majority of intravenous medications tested were found to be physically compatible with meropenem/vaborbactam. These data will help pharmacists and nurses to improve line access in patients receiving meropenem/vaborbactam.  相似文献

Introduction

Medication adherence is critical in chronic immune-mediated inflammatory diseases (IMIDs) and could be affected by patients’ treatment-related beliefs. The objective of this study was to determine beliefs about systemic medications in patients with IMIDs and to explore the association of those beliefs and other factors with adherence.

Methods

This was a multi-country, cross-sectional, self-administered survey study. Included were adults diagnosed with one of six IMIDs receiving conventional systemic medications and/or tumor necrosis factor inhibitors (TNFi). Patients’ necessity beliefs/concerns towards and adherence to treatments were assessed by the Beliefs about Medicines Questionnaire and four-item Morisky Medication Adherence Scale. Correlation of patients’ beliefs about treatment and other factors with adherence were evaluated by multivariable regression analyses.

Results

Among studied patients (N = 7197), 32.0% received TNFi monotherapy, 27.7% received TNFi–conventional combination therapy, and 40.3% received conventional medications. Across IMIDs, high adherence to systemic treatment was more prevalent in TNFi groups (61.3–80.7%) versus corresponding conventional treatment groups (28.4–64.7%). In at least four IMIDs, greater perception of the illness continuing forever (P < 0.001), of the treatment helping (P < 0.001), and more concerns about the illness (P < 0.01), but not clinical parameters, were associated with higher treatment necessity beliefs. Higher treatment necessity beliefs, older age, Caucasian race, and TNFi therapy were associated with high medication adherence in at least four IMIDs.

Conclusions

Treatment necessity beliefs were higher than concerns about current medication in patients with IMID. Illness perceptions had a greater impact on treatment necessity beliefs than clinical parameters. Older age, greater treatment necessity beliefs, and TNFi therapy were associated with high self-reported medication adherence in at least four IMIDs.

Purpose

The purpose of this study was to compare the adherence of the glimepiride/metformin sustained release (GM-SR) once-daily fixed-dose combination and glimepiride/metformin immediate release (GM-IR) BID fixed-dose combination in type 2 diabetes therapies.

Methods

An open-label, randomized, multicenter, parallel-group study was conducted at 11 hospitals in the Republic of Korea. A total of 168 patients with type 2 diabetes treated with >4 mg of glimepiride and 1000 mg of metformin by using free or fixed-dose combination therapy for at least 2 weeks were enrolled. Patients were randomized to receive GM-SR 4/1000 mg once-daily or GM-IR 2/500 mg BID for 24 weeks. Adherence was compared by using the Medication Event Monitoring System (MEMS).

Findings

A significant difference in adherence was observed between the 2 groups. Overall adherence, defined by the number of container openings divided by the number of prescribed doses, was 91.7% in the GM-SR group and 88.6% in the GM-IR group (P < 0.001). The percentage of treatment days with the correct number of doses taken was 85.3% in the GM-SR group and 75.1% in the GM-IR group (P < 0.001). The percentage of missed doses was 11.7% in the GM-SR group and 15.3% in the GM-IR group (P < 0.001). The percentage of doses taken in the correct time window and therapeutic coverage were higher in the GM-SR group (P < 0.001). There was no significant difference in glycosylated hemoglobin changes or number of adverse events between the 2 groups. A total of 168 patients randomized to receive GM-SR once daily (86 patients) or GM-IR twice daily (82 patients). Mean Age were 57.8 ± 9.6 years old. Male : female ratio was 47.6 : 52.4 %. Body mass index were 66.3 ± 12.0 kg/m2, Diabetes duration were 10.5 ± 6.6 years.

Implications

This study showed that patient adherence with GM-SR once daily was significantly better than with GM-IR BID. ClinicalTrials.gov identifier: NCT01620489.  相似文献

Purpose

We performed a meta-analysis to investigate the legacy effect of >5 years of intensive blood glucose lowering on cardiovascular outcomes in patients with type 2 diabetes and very high risk or secondary prevention of cardiovascular disease (CVD).

Methods

We mainly searched PubMed, Embase, and the Cochrane Library for relevant randomized controlled trials. Patients in the included studies had intensive glucose lowering for >5 years and posttrial follow-up for at least 5 years. Primary end points were all-cause mortality and cardiovascular death. Secondary end points were major macrovascular events, myocardial infarction, and stroke. We used risk ratios (RRs) with 95% CIs as summary statistics.

Findings

We included 3 trials that involved 13,684 patients, of whom 6805 received intensive glucose-lowering treatment and 6879 received standard treatment. The mean total follow-up duration was 10.3 years, which included 5.4 years of in-trial intervention and 5.5 years of posttrial follow-up. Intensive glucose control treatment did not significantly reduce all-cause mortality (RR = 0.98; 95% CI, 0.87–1.10) or cardiovascular death (RR = 0.97; 95% CI, 0.87–1.09). No significant risk reduction was found for stroke (RR = 1.02; 95% CI, 0.92–1.14), myocardial infarction (RR = 0.91; 95% CI, 0.75–1.09), or major macrovascular events (RR = 0.99; 95% CI, 0.93–1.06).

Implications

A legacy effect of >5-year intensive blood glucose control on cardiovascular outcomes in patients with type 2 diabetes and very high risk or secondary prevention of CVD was not detected, although this effect might be applicable in patients with diabetes and primary prevention of CVD. Further investigation of the legacy effect in different CVD risk populations should therefore be performed.  相似文献

Purpose

Although vancomycin has been the mainstay of therapy for methicillin-resistant Staphylococcus aureus (MRSA) infections, its effectiveness has been challenged. Combination therapy may be used for patients with persistent MRSA bacteremia refractory to initial therapy. Studies have reported in vitro synergy between vancomycin and ceftaroline; however, clinical experience with this therapy is limited. Here, we report our experience with 5 cases of vancomycin-refractory MRSA bacteremia treated with the combination of vancomycin and ceftaroline.

Methods

Between January 2014 and August 2016, 5 patients were identified who received vancomycin and ceftaroline combination therapy due to persistent bacteremia or deterioration of their clinical status on vancomycin alone (despite a vancomycin MIC within the susceptible range).

Findings

Five patients presented with MRSA bacteremia secondary to endocarditis (n = 2), epidural abscess (n = 2), or left iliopsoas abscess (n = 1). Four of the 5 patients experienced microbiologic cure, and 1 patient transitioned to palliative care.

Implications

This case series serves to describe additional clinical experience with vancomycin and ceftaroline combination therapy. This combination may be considered when vancomycin monotherapy does not lead to microbiological and/or clinical improvement in patients with metastatic MRSA bacteremia. Additional studies are warranted to further define its role in salvage therapy for persistent MRSA bacteremia.  相似文献

Purpose

Fixed-combination drug products (FCDPs) combining dapagliflozin and metformin extended release (XR) may provide patients with type 2 diabetes mellitus with an alternative antihyperglycemic treatment, which could improve adherence by reducing tablet burden. This study evaluated the bioequivalence of dapagliflozin/metformin XR FCDP versus the co-administration of the individual monotherapy tablets currently available for use in the Russian Federation.

Methods

Healthy subjects aged 18 to 45 years were enrolled in this randomized, open-label, 2-period crossover study, conducted in a single Russian center. Pharmacokinetic parameters (AUC0–t, Cmax, and Cmax/AUC0–t) were used to assess bioequivalence of dapagliflozin/metformin XR (10/1000 mg) FCDP to the individual component tablets (dapagliflozin [10 mg] plus metformin XR [2 × 500 mg]) under standard fed conditions. Safety and tolerability were also assessed.

Findings

Forty healthy subjects were included (47.5% male; mean age, 30 years; and mean body mass index, 24.2 kg/m2). Dapagliflozin and metformin XR in the FCDP were bioequivalent to the individual component tablets marketed in the Russian Federation, with the 90% CIs of the geometric least-squares mean ratios for all key pharmacokinetic parameters being contained within the 80% to 125% bioequivalence limits. Both FCDP and the individual component formulations were well tolerated, with no serious adverse events.

Implications

Bioequivalence of dapagliflozin/metformin XR FCDP and the individual components was established without any new safety concerns, presenting a safe alternative for patients currently receiving regimens including each component individually. ClinicalTrials.gov identifier: NCT02722239.  相似文献

Purpose

Techniques used to identify AmpC β-lactamases in SPICE (Serratia, Pseudomonas, indole-positive Proteus, Citrobacter, and Enterobacter) organisms are not yet optimized for the clinical laboratory and are not routinely used. Clinicians are often left with an uncertainty on the choice of antibiotic when a SPICE organism is isolated. The purpose of this study was to evaluate the outcomes of carbapenem versus noncarbapenem regimens in treating bacteremia or urinary tract infection from a SPICE organism in clinical practice.

Methods

This single-center, retrospective, cohort study analyzed data from adult patients who had clinical infection with a SPICE organism isolated from blood or urine cultures. Patients were assigned to a carbapenem- or noncarbapenem-treated group. The primary end point was clinical response, defined as a resolution of signs and symptoms of infection at the end of therapy.

Findings

A total of 332 patients were assessed, and 145 patients met the inclusion criteria for the study. There were 20 patients who received a carbapenem, while 125 received a noncarbapenem regimen. The percentage of patients who were bacteremic was 46.2%. Clinical response overall was achieved in 80% of patients on a carbapenem versus 90.3% of patients on a noncarbapenem regimen (P = 0.24). The rate of microbiologic cure was 90% in patients on a carbapenem versus 91.2% in patients on a noncarbapenem regimen (P = 1).

Implications

In this study in patients treated for infection with a SPICE organism in clinical practice, the rates of clinical response did not differ significantly between the carbapenem and noncarbapenem groups. Current CLSI breakpoints set for SPICE organisms may still be reliable and may not require additional testing for AmpC β-lactamases.  相似文献

Purpose

As part of the approval process, regulatory authorities often require postauthorization studies that involve patient registries; it is unknown, however, whether such registry studies are adequately completed. We investigated whether registry studies for new drugs were performed as agreed at time of approval.

Methods

This study reviewed protocols and follow-up reports for 73 registry studies that were proposed for 43 drugs approved by the Committee for Medicinal Products for Human Use in Europe in the period 2007 to 2010.

Results

The data lock point of January 1, 2016, was taken to allow a 5-year follow-up period for each drug after approval. At that time, 2 studies (3%) in registries had been finalized, 19 registries (26%) had not enrolled any patients, and 52 studies (71%) were ongoing. The median enrollment was 31% (interquartile range [IQR], 6–104) of the required number of patients for 41 registry studies that had a predefined sample size, 30% (IQR, 2–101) for nonimposed registries, and 61% (IQR, 18–144) for imposed registries.

Implications

Enrollment of patients into postapproval registries is poor, although the results for imposed registries seem better. Currently, registries only have a limited impact on resolving gaps in the knowledge of a drug’s benefits and risks at time of marketing authorization.  相似文献

Purpose

The aim was to investigate the stability of cefazolin in elastomeric infusion devices.

Methods

Elastomeric devices (Infusor LV) that contain cefazolin (3 g/240 mL and 6 g/240 mL) were prepared and stored at 4°C for 72 hours and then at 35°C for 12 hours, followed by 25°C for 12 hours. An aliquot was withdrawn at predefined time points and analyzed for the concentration of cefazolin. Samples were also assessed for changes in pH, solution color, and particle content.

Findings

Cefazolin retained acceptable chemical and physical stability over the studied storage period and conditions.

Implications

These findings will allow the administration of cefazolin by the Infusor LV elastomeric device in the outpatient and remote settings.  相似文献

Purpose

Liposomal amphotericin B (L-AMB) is an essential antifungal agent for patients with hematologic diseases; however, the drug causes severe hypokalemia at a high frequency. Meanwhile, there is little evidence regarding the risk factors for L-AMB–induced severe hypokalemia, and the prevention protocol has not been established. The goal of this study was to identify the risk factors related to severe hypokalemia induced by L-AMB in hematologic patients.

Methods

Seventy-eight hematologic patients with a first administration of L-AMB were enrolled in the study. Eleven patients who had serum potassium levels <3.0 mmol/L before L-AMB administration and 12 patients who received L-AMB administration within 3 days were excluded. Patients who had a serum potassium level <3.0 mmol/L during L-AMB administration were classified into a hypokalemia group (n = 26), and those who had a serum potassium level ≥3.0 mmol/L were classified into a non-hypokalemia group (n = 29). The patient characteristics were analyzed retrospectively. In addition, the usefulness of potassium supplementation was analyzed for those patients who received potassium formulations (non-hypokalemia group, n = 15; hypokalemia group, n = 24).

Findings

Twenty-six patients had hypolalemia after L-AMB administration. Hypokalemia with serum potassium levels <3.0 mmol/L was observed ~7 days after starting L-AMB administration. The patient characteristics, L-AMB dose, and L-AMB administration period did not differ between the 2 groups. In the patients who received potassium formulations, the period between starting L-AMB administration and starting potassium supplementation was significantly shorter in the non-hypokalemia group than in the hypokalemia group (median, 0 vs 4 days, respectively; P < 0.01); the potassium dose was not different between the 2 groups. A receiver-operating characteristic curve revealed that the cutoff time for the start of potassium supplementation to reduce the incidence of L-AMB–induced hypokalemia was 3 days. Multivariate logistic regression analysis revealed that beginning potassium supplementation within 2 days from the start of L-AMB administration was an independent factor reducing the risk of L-AMB–induced hypokalemia (odds ratio, 0.094 [95% CI, 0.019–0.47]).

Implications

This study showed that starting administration of a potassium formulation within 2 days from the start of L-AMB administration was a risk reduction factor for L-AMB–induced hypokalemia. This finding indicates that early potassium supplementation should be incorporated into the regimen of hypokalemia management when L-AMB is used.  相似文献

Purpose

Recent controversies on the safety profiles of opioids and paracetamol (acetaminophen) have led to changes in clinical guidance on osteoarthritis (OA) management. We studied the existing association between the use of different OA drug therapies and the risk for acute coronary events.

Methods

A cohort of patients with clinically diagnosed OA (according to ICD-10 codes) was identified in the SIDIAP database. Within the cohort, cases with incident acute coronary events (acute myocardial infarction or unstable angina) between 2008 and 2012 were identified using ICD-10 codes and data from hospital admission. Controls were matched 3:1 to acute coronary event–free patients matched by sex, age (±5 years), geographic area, and years since OA diagnosis (±2 years). Linked pharmacy dispensation data were used for assessing exposure to drug therapies. Multivariate conditional logistic regression models were fitted to estimate adjusted odds ratios of acute coronary events.

Findings

Totals of 5663 cases and 16,989 controls were studied. Previous morbidity and cardiovascular risk were higher in cases than in controls, with no significant differences in type or number of joints with OA. Multivariate adjusted analyses showed increased risks (odds ratio; 95% CI) related to the use of diclofenac (1.16; 1.06–1.27), naproxen (1.25; 1.04–1.48), and opioid analgesics (1.13; 1.03–1.24). No significant associations were observed with cyclooxygenase-2 selective NSAIDs, topical NSAIDs, glucosamine, chondroitin sulfate, paracetamol, or metamizole.

Implications

In patients with clinically diagnosed OA, the use of nonselective NSAIDs or opioid analgesics is associated with an increased risk for acute coronary events. These risks should be considered when selecting treatments of OA in patients at high cardiovascular risk.  相似文献
