Outcomes of Stable Multiple Sclerosis Patients Staying on Initial Interferon Beta Therapy Versus Switching to Another Interferon Beta Therapy: A US Claims Database Study

Introduction

This study was designed to assess real-world outcomes of patients with multiple sclerosis (MS) who were stable on interferon (IFN) beta therapy in the year prior to switching to another IFN beta therapy versus those who continued on the initial treatment.

Methods

This study used administrative claims from MarketScan Commercial Claims and Encounters Database, from January 1, 2010, to March 31, 2015, to identify MS patients aged 18–64 years who remained relapse free for at least 1 year while continuously treated with an IFN beta therapy. Stable patients remaining on their initial IFN beta therapy (no-switch patients) were matched with stable patients who switched IFN beta therapy (switch patients) using propensity score matching (first claim?=?index date). Outcome measures included annualized relapse rate (ARR), the percentage of patients who relapsed, medication possession ratio, and the proportion of days covered and were measured during the year following the index date.

Results

This study identified 531 patients in the no-switch group and 177 patients in the switch group, with subsets of 270 patients in the no-switch group and 90 patients in the switch group stable on intramuscular (IM) IFN beta-1a therapy. All outcomes during the follow-up year were significantly better in the no-switch group than in the switch group. For all patients, ARR in the switch group was more than twice that in the no-switch group (P?=?0.002). For patients stable on IM IFN beta-1a at baseline, ARR was twice as high in the switch group as in the no-switch group (P?=?0.012).

Conclusion

Among all patients stable on IFN beta therapy and the subset stable on IM IFN beta therapy in particular, those who remained on therapy had significantly better outcomes than those who switched to another IFN beta therapy.

72-Week Safety and Tolerability of Dimethyl Fumarate in Japanese Patients with Relapsing-remitting Multiple Sclerosis: Analysis of the Randomised,Double Blind,Placebo-Controlled,Phase III APEX Study and its Open-Label Extension

Introduction

The long-term safety of dimethyl fumarate (DMF) in patients with relapsing-remitting multiple sclerosis (RRMS) has been studied in mainly Caucasian patients. The present interim analysis aimed to evaluate the 72-week safety of DMF in Japanese patients with RRMS.

Methods

Safety data of Japanese subjects enrolled in the 24-week randomised, double-blind, placebo-controlled APEX study (Part I) and its following open-label extension (Part II) were analysed at 72 weeks from the beginning of Part I. In Part I, subjects were randomised to DMF treatment or matching placebo while all subjects received DMF treatment during Part II. Adverse events (AEs) reported throughout the study period were recorded.

Results

Overall, 109 Japanese subjects completed 72 weeks of treatment. The incidence of AEs and serious AEs was 95% and 19%, respectively, in the DMF group compared with 84% and 18%, respectively, in the placebo group at 24 weeks. Common AEs (at least 5%) reported with treatment included nasopharyngitis, flushing, hot flush, gastrointestinal events, pruritus, rash, headache, increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST). AEs led to discontinuation of DMF in 5% of patients and included MS relapse, flushing, abdominal pain, liver disorder and increased ALT/AST. After an initial decrease from baseline of 17% in the DMF group at week 24, the mean lymphocyte counts stabilised and were maintained until week 72. No opportunistic/serious infections nor malignancies were reported with DMF treatment. The incidences of AEs, serious AEs, and discontinuation due to AEs were similar between the DMF and the placebo groups.

Conclusion

The 72-week safety profile of DMF in Japanese patients with RRMS was consistent with previous studies that enrolled mostly Caucasian patients, with a lower incidence of flushing and related symptoms and a lower reduction in the lymphocyte count compared with previous reports.

Étude du Transport INTrA-Hospitalier du MAlade de Réanimation (TINTAHMAR)

Introduction

Intra-hospital transport (IHT) of critically ill patients is a frequent care associated with an important risk of adverse events (AEs). To decrease the occurrence of AEs, recent guidelines have been edited. Their consequences on adverse event incidence and nurse workload have not been assessed.

Aim of study

The primary objective was to assess the time necessary for the achievement of IHT. Secondary objectives were to describe practices related to IHT, to compare workload according to the presence of nurses during the IHT, and to assess the occurrence of AEs.

Patients and methods

This French multicentric observational study conducted by the SRLF was conducted in 18 French-speaking intensive care units. All critically ill adults requiring IHT were included.

Results

Three hundred and ninety-six IHTs (mean age 61 ±19, mean IGS II 46±24) were assessed. The mean duration of IHT was 67±35 minutes. There was a training program of IHT in only 11% of centers, a check-list in 22%, and traceability procedures in 17%. There was a nurse during the IHT in 51% of cases. The presence of a nurse had no consequence on IHT durations. Adverse events occurred in 15% of IHT. In multivariable analysis, nurse presence was not associated with IHT associated AEs.

Conclusion

An IHT requires time. Despite the poor adherence to the guidelines, this care was associated with low incidence of AES. The presence of nurses during the IHT had no consequence on IHT duration and AEs occurrence.

     

Mavoglurant Augmentation in OCD Patients Resistant to Selective Serotonin Reuptake Inhibitors: A Proof-of-Concept,Randomized, Placebo-Controlled,Phase 2 Study

Introduction

To determine if mavoglurant (modified release) as an augmentation therapy to selective serotonin reuptake inhibitors (SSRIs) could have beneficial effects reducing Yale–Brown Obsessive Compulsive Scale (Y-BOCS) total score in patients with obsessive–compulsive disorder (OCD) resistant to SSRI treatment.

Methods

This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase 2 study. Patients remained on their SSRI treatment and mavoglurant or placebo was added on. Non-smoking men and women aged 18–65 years primarily diagnosed with OCD according to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) criteria were randomized (1:1) to mavoglurant or placebo groups. After 50 patients were randomized, an interim analysis was conducted to determine whether the study should be continued. The primary outcome measure was absolute change in Y-BOCS from baseline at week 17. Safety was assessed by recording adverse events (AEs) and serious adverse events (SAEs).

Results

Interim analysis led to a decision to terminate the study. In total 38 (76.0%) participants completed 17 weeks of treatment and 37 (74.0%) completed the study. There was no significant difference in least squares (LS) mean change from baseline at week 17 in Y-BOCS total score for mavoglurant compared with placebo groups [?6.9 (1.75) vs. ?8.0 (1.78), respectively; LS mean difference 1.1; 95% CI ?3.9, 6.2; p = 0.671]. The incidence of AEs was higher in the mavoglurant compared with the placebo group (80.8% vs. 70.8%, respectively).

Conclusion

This study of mavoglurant in OCD was terminated because of the lack of efficacy at interim analysis. The study did not support the use of an antagonist of mGluR5 receptors for OCD treatment.

Trial Registration

The study was registered with ClinicalTrials.gov: NCT01813019.

Surgical process analysis identifies lack of connectivity between sequential fluoroscopic 2D alignment as a critical impediment in femoral intramedullary nailing

Purpose

Identifying key steps and barriers within complex and simple surgical procedures can be accomplished in a structured and rigorous manner using surgical process modeling. For lower extremity long bone fracture stabilization, the current standard of care is closed intramedullary (IM) nailing, which, despite its widespread use, is associated with challenges that greatly impact operative time and lead to the frustration of medical staff. The aim of this study was to identify challenging surgical steps in IM nailing and understand their underlying causation.

Methods

Eight semi-structured interviews with staff orthopedic surgeons and eight detailed surgical observations were conducted to understand the surgical steps, challenges and adapted techniques used in IM nailing. Hierarchical decomposition was then utilized to structure the IM nailing surgical procedure into phases, steps and activities.

Results

In the developed IM nailing surgical process model, the most challenging steps were identified as fracture reduction (75 %) and entry point selection (25 %), both of which were associated with high levels of frustration in the observed surgeries. Both of these steps utilize 2D fluoroscopic imaging to guide 3D alignment. Challenges arise when the alignment in one plane is lost while adjusting the alignment in the perpendicular plane. This leads to unpredictable repetition of activities which can be time-consuming and frustrating.

Conclusion

Identifying the causation of surgical challenges in IM nailing through surgical process modeling forms a knowledge base that can be used to guide future improvements to techniques and surgical instrumentation.

     

Pharmacokinetics and Safety of DS-8500a,an Antidiabetic Drug,in Japanese Subjects with Hepatic or Renal Impairment: A Single-Center,Open-Label,Single-Dose Study

Introduction

The pharmacokinetics, safety, and tolerability of DS-8500a (a G protein receptor 119 agonist) up to 100 mg have been investigated in healthy Japanese adults. The objective of this study was to evaluate the effects of hepatic or renal impairment on the pharmacokinetics of a single 25-mg oral dose of DS-8500a.

Methods

This single-center, open-label study enrolled subjects into eight groups according to hepatic function (normal; mild or moderate impairment) and renal function [normal; mild, moderate, or severe impairment; and end-stage renal disease (ESRD)]. Drug concentrations were measured by liquid-chromatography tandem mass spectrometry. Pharmacokinetic parameters were evaluated by non-compartmental analysis. Adverse events (AEs) were evaluated for safety.

Results

The hepatic and renal groups enrolled 15 and 30 subjects, respectively. Pharmacokinetic parameters of DS-8500a were comparable between the normal hepatic function and mild hepatic impairment groups, but the mean area under the concentration–time curve (AUC) was 1.37-fold higher, and the half-life was longer in the moderate hepatic impairment group compared with the normal hepatic function group. The maximum concentration (C_max) and AUC values were 0.704- and 0.609-fold lower, respectively, in the ESRD group compared with the values in the other renal impairment groups; no clear differences in AUC and time to C_max were observed in the normal function and mild, moderate, and severe renal impairment groups. There was no relationship between apparent total body clearance and estimated glomerular filtration rate. The incidence of AEs was similar among all groups.

Conclusion

DS-8500a exposure in the mild hepatic impairment and mild to severe renal impairment groups was similar to that in the corresponding normal hepatic and renal function groups, but dose adjustments may be required in those with moderate hepatic impairment and ESRD.

Effects of Ketoconazole on the Pharmacokinetics of Mifepristone,a Competitive Glucocorticoid Receptor Antagonist,in Healthy Men

Introduction

Mifepristone, a competitive glucocorticoid receptor antagonist approved for Cushing syndrome, and ketoconazole, an antifungal and steroidogenesis inhibitor, are both inhibitors of and substrates for cytochrome P450 (CYP3A4). This study evaluated the pharmacokinetic effects of concomitant ketoconazole, a strong CYP3A4 inhibitor, on mifepristone.

Methods

In an open-label, two-period, single-center study, healthy adult men received mifepristone 600 mg orally daily for 12 days (period 1) followed by mifepristone 600 mg daily plus ketoconazole 200 mg orally twice daily for 5 days (period 2). Serial pharmacokinetic blood samples were collected predose and over 24 h postdose on days 12 (period 1) and 17 (period 2). A cross-study comparison (using data on file) further examined whether systemic exposure to mifepristone plus ketoconazole exceeded the exposure following mifepristone 1200 mg orally administered for 7 days.

Results

Sixteen subjects were enrolled and 14 completed the study. Concomitant administration with ketoconazole increased the systemic exposure to mifepristone, based on geometric least squares mean ratios, by 28% for C _max and 38% for AUC_0–24. This increase was 85% and 87% of the exposure observed following mifepristone’s highest label dose of 1200 mg/day for C _max and AUC_0–24, respectively. Adverse events (AEs) were reported in 56.3% (9/16) of subjects during administration of mifepristone alone and in 57.1% (8/14) during combination with ketoconazole. No serious AEs were reported.

Conclusion

Systemic exposure to mifepristone increased following multiple doses of mifepristone 600 mg daily plus ketoconazole 200 mg twice daily. Little to no increase in AEs occurred. Dose adjustment of mifepristone may be needed when given with ketoconazole.

Multicenter,Randomized, Controlled Study Comparing Tafluprost/Timolol Fixed Combination with Latanoprost/Timolol Fixed Combination in Primary Open-Angle Glaucoma and Ocular Hypertension

Introduction

This was the first exploratory randomized controlled study to compare the efficacy and safety of a preserved tafluprost/timolol fixed combination (TAF/TIM) with a preserved latanoprost/timolol fixed combination (LAT/TIM).

Methods

This prospective, randomized, open-label study was conducted in Japanese patients with primary open-angle glaucoma, including normal-tension glaucoma or ocular hypertension. Following a 4-week LAT/TIM run-in period, eligible patients entered a 12-week treatment period, during which they received either LAT/TIM or TAF/TIM. The efficacy endpoint was the change in intraocular pressure (IOP) from baseline to week 12 and the safety endpoints included the changes from baseline to week 12 in superficial punctate keratopathy (SPK) score, tear breakup time (TBUT), and hyperemia score, as well as adverse events (AEs). At week 6, ocular symptoms were evaluated using a questionnaire.

Results

In total, 131 patients provided informed consent. Of these, 115 completed the run-in period and were assigned to receive TAF/TIM (n?=?60) or LAT/TIM (n?=?55). At week 12, there were no significant differences between the TAF/TIM and LAT/TIM groups in the change from baseline in trough IOP and IOP at 4–6 h after instillation. There were no significant differences between the two groups in the change from baseline to week 12 in SPK score, TBUT, and hyperemia score. However, only in the TAF/TIM group, the total SPK score and the inferior cornea SPK score were significantly lower at week 12 compared with baseline. Eye irritation and eye pain were significantly decreased in the TAF/TIM group compared with the LAT/TIM group. Two treatment-related AEs were reported in the TAF/TIM group (3.3%) and none in the LAT/TIM group, while no serious AEs were reported in either group.

Conclusion

TAF/TIM is as effective as LAT/TIM in terms of IOP-reducing effect, with fewer ocular symptoms. TAF/TIM was associated with a significant improvement in SPK scores.

The GENDER ATTENTION Observational Study: Gender and Hormonal Status Differences in the Incidence of Adverse Events During Cyclosporine Treatment in Psoriatic Patients

Introduction

Female sex has been shown to be a risk factor for the development of adverse drug reactions; however, this has not been studied for cyclosporine (CsA). The aim of this study was to investigate, in Italian dermatological practice, the influence of gender and menopause and related hormones on the incidence of adverse events (AEs) during CsA treatment in psoriatic patients.

Methods

Multicenter, prospective, observational study conducted from May 2011 to June 2013. Patients with plaque psoriasis, undergoing a new CsA administration course, or about to start it, were enrolled in the outpatient clinics of Italian dermatological centers. During the 2–6 months of study duration, patients had to note all AEs that occurred in a diary that was reviewed by the investigators at the follow-up visit. Sex hormone levels were measured within 7 days from the start date of a menstrual cycle.

Results

A total of 969 adult psoriatic patients were enrolled in the study, divided into four cohorts: fertile women and corresponding age-matched men; postmenopausal women and corresponding age-matched men. A significant difference in the percentage of patients with AEs was observed between fertile and postmenopausal women, but not between women and age-matched men. AE incidence rate was about 37% higher in fertile women than in age-matched men and about 18% higher in postmenopausal women than in age-matched men, but differences were not statistically significant. Incidence rate ratio of fertile vs. postmenopausal women was 0.67, reaching statistical significance. AEs were mild or moderate in severity in the great majority of patients of all cohorts and postmenopausal women had significantly less grade 1–2 AEs compared to fertile women, but more grade 3–4 AEs. FSH levels were significantly higher in postmenopausal women reporting no AEs, and DHEA sulfate levels were about 10% higher in men with no AEs, compared to those reporting at least one AE. Cortisol levels were slightly though significantly higher in postmenopausal women with no AE.

Conclusions

A better understanding of sex- and hormone-related influences on drug responses may help to improve drug safety and efficacy, by permitting one to tailor pharmacological treatments to individual subjects or defined patient cohorts.

Effectiveness and Tolerability of Micafungin in Chinese Patients with Invasive Fungal Infections: A Retrospective,Multicenter Study

Introduction

Invasive fungal infections (IFIs) are a significant health problem in immunocompromised patients, resulting in substantial morbidity, mortality, and healthcare costs. Micafungin is a broad-spectrum echinocandin with activity against Candida and Aspergillus spp. This was a multicenter, non-comparative, retrospective observational study that evaluated the effectiveness and tolerability of intravenously administered micafungin for treating IFIs caused by Candida and Aspergillus spp.

Methods

Adult patients in China who had received at least one dose of intravenously administered micafungin were eligible. Retrospective data (May 2008–April 2015) were extracted from patients’ medical files and recorded using electronic data capture. The primary endpoint was overall success rate (patients with complete or partial response). Subgroup analyses determined effectiveness according to diagnostic certainty, fungal species, type of IFI, duration of micafungin treatment, and daily dose of micafungin. Tolerability, including the incidence of adverse events (AEs), was also assessed.

Results

Overall, 2555 patients who received at least one dose of micafungin were identified. The mean duration of treatment and mean daily dose were 10.2 days and 133.0 mg, respectively. The overall success rate was 60.8%; this was significantly higher in patients who received treatment for at least 1 week (range 67.9–71.6% [mean 69.2%]) compared with less than 1 week (47.8%; P?<?0.0001), and those who received 50–100 mg (65.7%) compared with other daily doses (range 42.9–60.1% [mean 59.0%]; P?=?0.0011). Success rates in Candida- and Aspergillus-infected patients were similar (61.9% and 56.8%, respectively). AEs and adverse drug reactions were observed in 36.2% and 4.5% of patients, respectively. The majority of AEs were mild, while discontinuation due to AEs was low (2.3%).

Conclusion

Micafungin is effective and well tolerated for the treatment of patients with IFIs in China, as demonstrated in Candida- and Aspergillus-infected adults. Subgroup analyses highlighted the potential benefits of treating IFIs with micafungin for a minimum of 1 week.

Long-term Safety and Efficacy of Latanoprostene Bunod 0.024% in Japanese Subjects with Open-Angle Glaucoma or Ocular Hypertension: The JUPITER Study

Introduction

Latanoprostene bunod (LBN) is a novel nitric oxide (NO)-donating prostaglandin F2α analog. We evaluated the long-term safety and intraocular pressure (IOP)-lowering efficacy of LBN ophthalmic solution 0.024% over 1 year in Japanese subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Methods

This was a single-arm, multicenter, open-label, clinical study. Subjects aged 20 years and older with a diagnosis of OAG or OHT instilled 1 drop of LBN ophthalmic solution 0.024% in the affected eye(s) once daily in the evening for 52 weeks and were evaluated every 4 weeks. Safety assessments included vital signs, comprehensive ophthalmic exams, and treatment-emergent adverse events (AEs). Absolute and percent reductions from baseline in IOP were also determined.

Results

Of 130 subjects enrolled, 121 (93.1%) completed the study. Mean age was 62.5 years, and mean (standard deviation) baseline IOP was 19.6 (2.9) and 18.7 (2.6) mmHg in study eyes and treated fellow eyes, respectively. Overall, 76/130 (58.5%) and 78/126 (61.9%) subjects experienced ≥1 AEs in study eyes and treated fellow eyes, respectively. In both study eyes and treated fellow eyes, the most common AEs were conjunctival hyperemia, growth of eyelashes, eye irritation, and eye pain. At 52 weeks, 9% of treated eyes had an increase in iris pigmentation compared with baseline based on iris photographs. No safety concerns emerged based on vital signs or other ocular assessments. Mean reductions from baseline in IOP of 22.0% and 19.5% were achieved by week 4 in study and treated fellow eyes, respectively. These reductions were maintained through week 52 (P < 0.001 vs. baseline at all visits).

Conclusion

Once daily LBN ophthalmic solution 0.024% was safe and well-tolerated in Japanese subjects with OAG or OHT when used for up to 1 year. Long-term treatment with LBN ophthalmic solution 0.024% provided significant and sustained IOP reduction.

The Effectiveness of an Educational Brochure as a Risk Minimization Activity to Communicate Important Rare Adverse Events to Health-Care Professionals

Introduction

Educational brochures are an important tool for communicating risk to health-care professionals. It is important to evaluate the impact of any risk minimization tool to understand the effectiveness of the strategy. The objective of this study was to assess the effectiveness (i.e., respondents’ awareness and understanding of the communication) of a targeted educational brochure distributed to health-care professionals (HCPs) as a risk minimization strategy for the communication of new rare and important adverse events (AEs).

Methods

A prospective, non-interventional, online survey was performed following distribution of a specifically designed brochure highlighting new and important adverse events to a targeted HCP population, consisting of known users of the target medicine, as represented by a commercial database. Predefined multiple-choice survey questions assessed overall HCP awareness of the brochure and understanding and retention of information in those HCPs who reported receiving the brochure.

Results

The educational brochure was sent to a total of 565 HCPs; 121 (21.4%) responded to the survey. The majority of respondents (95.0%) had previously prescribed or dispensed the target medicine. In all, 88 (72.7%) respondents said they had received the educational brochure, of whom 95.5% stated they had at least scanned the main points. More participants who had received the brochure (86.4% to 96.6%) answered the five individual survey questions correctly compared with those who did not (51.5% to 97.0%); this was significant for four out of five questions (P ≤ 0.005). Significantly more HCPs who received the brochure achieved the predefined pass rate (at least four of five questions answered correctly) compared with HCPs who did not receive the brochure (93.2% vs 57.6%, respectively; P = 0.000003).

Conclusions

Distribution of targeted educational brochures may be an effective risk minimization strategy to raise HCP awareness of new rare and important AEs; educational brochures may also be an effective channel for sharing information on how these AEs can be best managed and on the importance and means of reporting AEs.

Olanzapine vs haloperidol: treating delirium in a critical care setting

Objective

To compare the safety and estimate the response profile of olanzapine, a second-generation antipsychotic, to haloperidol in the treatment of delirium in the critical care setting.

Design

Prospective randomized trial

Setting

Tertiary care university affiliated critical care unit.

Patients

All admissions to a medical and surgical intensive care unit with a diagnosis of delirium.

Interventions

Patients were randomized to receive either enteral olanzapine or haloperidol.

Measurements

Patient’s delirium severity and benzodiazepine use were monitored over 5 days after the diagnosis of delirium.

Main results

Delirium Index decreased over time in both groups, as did the administered dose of benzodiazepines. Clinical improvement was similar in both treatment arms. No side effects were noted in the olanzapine group, whereas the use of haloperidol was associated with extrapyramidal side effects.

Conclusions

Olanzapine is a safe alternative to haloperidol in delirious critical care patients, and may be of particular interest in patients in whom haloperidol is contraindicated.

     

The Safety of Fecal Microbiota Transplantation for Crohn’s Disease: Findings from A Long-Term Study

Introduction

Fecal microbiota transplantation (FMT) has been used as a potential treatment option for Crohn’s disease (CD). However, there is still lack of safety and efficacy evidence based on large samples of CD undergoing FMT. This study aimed to evaluate the risk factors of adverse event (AE) in the long term and the efficacy of FMT in the short term for patients with CD.

Methods

FMT via mid-gut for mild to severe CD in a single center trial (NCT01793831) was performed from October 2012 to December 2016. The possible factors with AE and efficacy after FMT were prospectively recorded.

Results

A total of 184 frequencies of FMT were performed for 139 patients who received FMT. During 1 month after FMT, 13.6% of mild AEs occurred, including increased frequency of defecation, fever, abdominal pain, flatulence, hematochezia, vomiturition, bloating and herpes zoster. No AE beyond 1 month was observed. Therefore, a 1 month cut-off could be suggested to define short-term and long-term AEs of FMT. Among the possible risk factors, only fecal microbiota purification methods were closely associated with the occurrence of AEs. The rate of AEs in patients undergoing manual methods for the preparation of fecal microbiota was 21.7%, which was significantly higher than the 8.7% in those experiencing an automatic method. The manual or automatic purification of fecal microbiota had no correlation with the efficacy of FMT.

Conclusion

This cohort study based on the largest size of cases demonstrated that improved fecal microbiota preparation reduced the rates of AEs, but did not affect the clinical efficacy in patients with CD.

     

Adherence to Long-Term Interferon Beta-1b Injection Therapy in Patients with Multiple Sclerosis Using an Electronic Diary

Introduction

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system requiring long-term treatment, which is often hampered by non-adherence to self-applicable therapies, provoking continued disease activity and health care system burdens. This study assessed the influence of a personal digital assistant (PDA) with diary function (n = 339 patients) on persistence and adherence to an interferon beta treatment regimen in comparison to a paper patient diary (n = 330 patients).

Methods

Patients who recently started with subcutaneous injections of interferon beta-1b were recruited in this prospective, non-interventional, national cohort study for an observational period of 2 years after successful completion of the initial dose escalation.

Results

Therapy persistence as assessed by the drop-out rate within 104 weeks was about 50% in both study cohorts. In male patients, the drop-out rate was 10% lower when using a PDA compared to the non-PDA group. Use of a PDA with an injection reminder function increased adherence to the injection schedule (every other day) by a mean of 24.5 injections over 24 months in comparison to use of a PDA without injection reminder function.

Conclusion

Persistence in this study was in the published range of observational MS studies. Furthermore, in male patients continuation of therapy might be positively influenced by use of a PDA, and both female and male patients might benefit from an integrated reminder function. In conclusion, electronic diaries reminding patients of upcoming injections can promote an improved adherence to MS therapy.

Concurrent Improvement in Both Binge Eating and Depressive Symptoms with Naltrexone/Bupropion Therapy in Overweight or Obese Subjects with Major Depressive Disorder in an Open-Label,Uncontrolled Study

Introduction

Binge eating disorder (BED) is associated with obesity and major depressive disorder (MDD). Naltrexone extended-release (ER)/bupropion ER (NB) is approved as an adjunct to diet and physical activity for chronic weight management. In a prospectively designed 24-week open-label, single-arm, single-site trial of 25 women with MDD and overweight/obesity, NB reduced weight and depressive symptoms.

Methods

This post hoc analysis investigated the relationship between change in self-reported binge eating behavior (evaluated with the Binge Eating Scale [BES]) and changes in weight, control of eating, and depressive symptoms.

Results

At baseline, 91% of subjects had moderate or severe BES scores, suggesting BED. BES scores were significantly improved from week 4, and by week 24, 83% reported “little or no problem.” Improvement in BES scores correlated with improvement in depressive symptoms and control of eating.

Conclusion

NB may be effective in reducing binge eating symptoms associated with MDD and overweight/obesity. Evaluation of NB in BED appears warranted.

Cost-Effectiveness Analysis of Isavuconazole vs. Voriconazole as First-Line Treatment for Invasive Aspergillosis

Introduction

Invasive aspergillosis (IA) is associated with a significant clinical and economic burden. The phase III SECURE trial demonstrated non-inferiority in clinical efficacy between isavuconazole and voriconazole. No studies have evaluated the cost-effectiveness of isavuconazole compared to voriconazole. The objective of this study was to evaluate the costs and cost-effectiveness of isavuconazole vs. voriconazole for the first-line treatment of IA from the US hospital perspective.

Methods

An economic model was developed to assess the costs and cost-effectiveness of isavuconazole vs. voriconazole in hospitalized patients with IA. The time horizon was the duration of hospitalization. Length of stay for the initial admission, incidence of readmission, clinical response, overall survival rates, and experience of adverse events (AEs) came from the SECURE trial. Unit costs were from the literature. Total costs per patient were estimated, composed of drug costs, costs of AEs, and costs of hospitalizations. Incremental costs per death avoided and per additional clinical responders were reported. Deterministic and probabilistic sensitivity analyses (DSA and PSA) were conducted.

Results

Base case analysis showed that isavuconazole was associated with a $7418 lower total cost per patient than voriconazole. In both incremental costs per death avoided and incremental costs per additional clinical responder, isavuconazole dominated voriconazole. Results were robust in sensitivity analysis. Isavuconazole was cost saving and dominant vs. voriconazole in most DSA. In PSA, isavuconazole was cost saving in 80.2% of the simulations and cost-effective in 82.0% of the simulations at the $50,000 willingness to pay threshold per additional outcome.

Conclusion

Isavuconazole is a cost-effective option for the treatment of IA among hospitalized patients.

Effect of synbiotic therapy on the incidence of ventilator associated pneumonia in critically ill patients: a randomised,double-blind,placebo-controlled trial

Objective

To investigate the effect of enteral Synbiotic 2000 FORTE^® (a mixture of lactic acid bacteria and fibre) on the incidence of ventilator associated pneumonia (VAP) in critically ill patients.

Design

Prospective, randomised, double blind, placebo controlled trial.

Setting

Tertiary referral centre, general Adult Intensive Care Unit (ICU).

Patients and participants

259 enterally fed patients requiring mechanical ventilation for 48 h or more were enrolled.

Intervention

All patients were enterally fed as per a standard protocol and randomly assigned to receive either synbiotic 2000 FORTE^® (twice a day) or a cellulose-based placebo for a maximum of 28 days.

Measurements and results

Treatment group (n = 130) was well matched with placebo group (n = 129) for age (mean 49.5 and 50 years, respectively) and APACHE II score (median 17 for both). Oropharyngeal microbial flora and colonisation rates were unaffected by synbiotics. The overall incidence of VAP was lower than anticipated (11.2%) and no statistical difference was demonstrated between groups receiving synbiotic and placebo in the incidence of VAP (9 and 13%, P = 0.42), VAP rate per 1,000 ventilator days (13 and 14.6, P = 0.91) or hospital mortality (27 and 33%, P = 0.39), respectively.

Conclusions

Enteral administration of Synbiotic 2000 FORTE^® has no statistically significant impact on the incidence of VAP in critically ill patients.

     

Nasal continuous positive airway pressure decreases respiratory muscles overload in young infants with severe acute viral bronchiolitis

Objective

To determine the efficacy of nasal continuous positive airway pressure (nCPAP) on respiratory distress symptoms and respiratory effort in young infants with acute respiratory syncytial virus bronchiolitis.

Design

Prospective study.

Setting

The paediatric intensive care unit of a university hospital.

Patients

Twelve infants less than 3 months of age, with severe respiratory distress.

Interventions

Respiratory distress was quantified with a specific scoring system. Oesophageal pressure (Pes) was measured during spontaneous ventilation before and after nCPAP, delivered through an infant-adapted ventilator. Simultaneous recording of gastric pressure (Pgas) was performed in the five oldest patients.

Measurements and results

The respiratory distress score decreased after nCPAP, particularly accessory muscles’ use and expiratory wheezing. The breathing pattern was modified, with shorter inspiratory and longer expiratory time. Pes swings and PTPes_insp, two indices of inspiratory effort, were reduced by 54 (±4)% and 59 (±5)%. PTPgas_exp, an indicator of expiratory muscles activity, was completely abolished. A significant correlation was observed between the respiratory distress score and Pes swings at baseline and after nCPAP.

Conclusions

In young infants with severe acute respiratory syncytial virus bronchiolitis, nCPAP rapidly unloads respiratory muscles and improves respiratory distress symptoms.
