RESUMO
BACKGROUND: Direct correlation of assessments of a validated composite measure such as the Asthma Control Questionnaire (ACQ) and risk of exacerbation has not been previously demonstrated in a randomized controlled trial. OBJECTIVE: To evaluate the ability of the ACQ score over time to predict risk of a future asthma exacerbation. METHODS: This analysis included data from a 12-week placebo-controlled trial (N = 292) of AMG 317, an IL-4 receptor α antagonist, in patients with moderate to severe atopic asthma. At baseline, patients had an ACQ score ≥1.5. Exacerbations were defined as requirement for systemic corticosteroids. A Cox proportional hazards model was used, with ACQ score as the time-dependent covariate. The analysis was repeated for individual components of the ACQ. RESULTS: Each 1-point increase in ACQ was associated with a 50% increased risk of exacerbation (hazard ratio, 1.50; 95% CI, 1.03-2.20) for the following 2-week period. Evaluation of individual ACQ components also demonstrated a similar trend, though each to a lesser degree than the full composite ACQ. CONCLUSION: Although based on a retrospective analysis, with small number of exacerbations, these findings support the utility of the composite ACQ score measurement to predict risk of future exacerbation in clinical trials and clinical practice. The composite ACQ score measurement was found to be a better predictor of future risk than individual ACQ components.

BACKGROUND: In two previous phase 3 studies, up to 60 weeks of etanercept therapy significantly improved the symptoms of psoriasis and was well tolerated. OBJECTIVE: To evaluate the long-term safety of etanercept in an open-label extension study for up to 72 weeks in patients with moderate-to-severe plaque psoriasis. METHODS: A total of 912 patients received 50 mg subcutaneous etanercept once weekly (OW) for the first 12 weeks of this extension study. Thereafter, eligible patients could maintain the 50 mg QW dose (n = 321) or escalate to 50 mg twice weekly (BIW; n = 591) anytime thereafter based on one of three predetermined criteria. RESULTS: Etanercept was well tolerated during 1056 patient-years of exposure; no difference was observed between the 50 mg QW and 50 mg BIW dosages in rates of adverse events and infections. Improvement in skin disease was maintained throughout the study. Patients who stopped and then restarted etanercept also showed improvement in psoriasis. CONCLUSION: Psoriatic patients continued to benefit from open-label etanercept treatment, both continuous and interrupted therapy, which was generally well tolerated after a combined 2.5 years of experience.

Introduction: Pruritus is the primary symptom of atopic dermatitis (AD). The objective of this study was to develop a patient-reported outcome (PRO) instrument for daily administration in clinical trials to measure AD-related itch in adolescents and adults that would meet the standards described in the US Food and Drug Administration's (FDA's) PRO Guidance.Materials and methods: Six focus groups were conducted with 49 patients with AD (32 adults; 17 adolescents). Three iterative rounds of cognitive debriefing interviews were conducted in 26 patients with AD (17 adults; 9 adolescents) to pretest and refine the instrument.Results: AD-related itching was considered the most bothersome AD symptom by nearly two-thirds of the focus group participants. The items in the initial version of the instrument, named the Atopic Dermatitis Itch Scale (ADIS), were developed to reflect concepts most relevant to the assessment of itching as described during the focus groups. Based on results of the cognitive debriefing interviews, an 8-item final version of the ADIS was created.Conclusion: The ADIS is a content valid PRO instrument addressing the concepts critical to the measurement of AD-related itching. To our knowledge, it is the first instrument developed to assess AD-related itch in patients as young as 12 years following the recommendations of the PRO Guidance.

OBJECTIVE: The 24-week Etanercept Assessment of Safety and Effectiveness (EASE) study evaluated the effectiveness and tolerability of continuous versus interrupted etanercept treatment in patients with moderate to severe plaque psoriasis. The objective of this analysis was to assess patient-reported outcomes (PROs) and health-care resource utilization (HRU) data from the EASE study. METHODS: Patients received open-label etanercept 50 mg twice weekly for 12 weeks and then received either continued or interrupted (single round of discontinuation and re-treatment with etanercept) etanercept 50 mg once weekly for the second 12 weeks. PROs included the following: 1) the patient global assessments of psoriasis, joint pain, and itching scores; 2) the Dermatology Life Quality Index; 3) the Medical Outcomes Study Short Form 36 vitality domain; 4) the Beck Depression Inventory; 5) the European Quality-of-Life Group Feeling Thermometer; and 6) a patient satisfaction survey. HRU was evaluated using the Economic Implications of Psoriasis patient questionnaire. RESULTS: Continuous treatment with etanercept 50 mg twice weekly for 12 weeks followed by 50 mg once weekly for 12 weeks produced sustained and clinically important improvements in PROs and reductions in HRU. Reductions in some outcome measures after treatment discontinuation at week 12 were observed in the interrupted group; however, most changes did not revert to baseline levels, consistent with some residual clinical effect, and re-treatment produced improvements similar to week 12 levels. CONCLUSIONS: Continuous etanercept treatment provided greater sustained improvements in PROs than interrupted therapy; however, interrupting etanercept therapy, if needed, has predictable and manageable effects.

BACKGROUND: Moderate to severe psoriasis is a significant inflammatory disease that frequently requires systemic therapies to effectively treat the underlying disorder. Etanercept and narrow-band ultraviolet light B (NB-UVB) are widely used to treat this disease. OBJECTIVE: To evaluate the effectiveness, tolerability, and patient-reported outcomes of combination etanercept plus NB-UVB phototherapy in moderate to severe plaque psoriasis. METHODS: This 12-week, single-arm, open-label study evaluated the combination of etanercept 50 mg twice weekly and NB-UVB thrice weekly in 86 patients. The primary outcome measure was > or =75% improvement from baseline in the Psoriasis Area and Severity Index (PASI 75). Other measures included PASI 90, PASI 100, and the Dermatology Life Quality Index (DLQI). RESULTS: At week 12, 26.0% achieved PASI 100, 58.1% achieved PASI 90, and 84.9% of patients achieved PASI 75. Mean improvement from baseline in DLQI was 84.4%. No unexpected, untoward adverse events were noted. CONCLUSIONS: A 12-week course of etanercept plus NB-UVB phototherapy was well tolerated and produced clinically meaningful improvements in signs and symptoms of moderate to severe plaque psoriasis and in patient-reported outcomes. Further investigation of the safety and efficacy of the use of such combination for this indication in controlled clinical trials would be of interest.

OBJECTIVE: We sought to examine whether psoriasis severity was associated with patient income and employment. METHODS: Respondents (> 30 years old) to National Psoriasis Foundation surveys (2003-2005) were classified by reported body surface area as having mild (< 3%), moderate (3%-10%), or severe (> 10%) psoriasis. The relationship between severity and household income (< $30,000 vs > or = $30,000) and employment was assessed by logistic regression, adjusting for age, age at onset, sex, race, and drug treatment. RESULTS: Probability of low income (< $30,000) was significantly greater among patients with severe disease than those with mild disease (P = .0002). Patients with severe disease had lower probability of working full time compared with patients with mild psoriasis but it was not statistically significant. Significantly more patients with severe psoriasis (17%) versus mild (6%) reported that psoriasis was the reason for not working (P = .01). LIMITATIONS: Household income was self-reported and may be influenced by household composition, which is unknown. Psoriasis severity was patient reported and not physician assessed. CONCLUSIONS: This study demonstrated that income and employment were negatively impacted among patients with severe psoriasis compared with mild psoriasis.

OBJECTIVE: We sought to assess whether patients with psoriasis with moderate or severe disease are being treated with systemic therapy. METHODS: Participants were identified from a random sample of the National Psoriasis Foundation contact database who were 18 years and older, with severe psoriasis (>10% body surface area) and moderate psoriasis (3%-10% body surface area); respondents with psoriatic arthritis were excluded. RESULTS: In all, 1657 respondents with psoriasis completed the survey (28% severe, 41% moderate). A total of 39% of respondents with severe psoriasis and 37% with moderate psoriasis were not currently receiving any treatment. Among respondents currently receiving therapy, only 43% of respondents with severe psoriasis received either traditional systemic therapy, biologic therapy, or phototherapy. LIMITATIONS: Respondents were from the National Psoriasis Foundation contact database and reported their current severity, which may be affected by their treatment. Body surface area as a measure of patient-reported severity has not been validated but has been used in several published studies. CONCLUSIONS: Almost 40% of respondents with psoriasis were currently not receiving treatment. For respondents with severe psoriasis, 26% were treated with systemic therapy, phototherapy, or both; 39% were not in treatment; and 35% were treated with topical therapy alone.

The Experience Diagnosing, Understanding Care, and Treatment with Enbrel (EDUCATE) trial is a phase IV, 24-week, multicenter, open-label study of etanercept 50 mg weekly in the treatment of psoriatic arthritis (PsA) in community dermatology clinics. In this study, patients with active PsA and moderate to severe plaque psoriasis have measurable uses of healthcare resources at baseline, reflecting a burden of illness. Etanercept significantly reduced healthcare resource utilization, absenteeism, and caregiver assistance in PsA patients after 24 weeks of treatment. These results could translate into savings on both direct and indirect costs and improvements in health-related quality of life for patients with PsA.

Mantle cell lymphoma (MCL) is a rare, aggressive, incurable B-cell malignancy. Ibrutinib has been shown to be highly active for patients with relapsed/refractory (R/R) MCL. The RAY trial (MCL3001) was a phase 3, randomized, open-label, multicenter study that compared ibrutinib with temsirolimus in patients with R/R MCL. Active disease is frequently associated with impaired functional status and reduced well-being. Therefore, the current study employed two patient-reported outcome instruments, the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) and the EQ-5D-5L, to assess symptoms, well-being, health status, and health-related quality of life of patients on treatment within the RAY trial. We found that patients on ibrutinib had substantial improvement in FACT-Lym subscale and total scores, and had improvement in EQ-5D-5L utility and VAS scores compared with temsirolimus patients, indicating a superior well-being. These improvements in well-being correlated with clinical response, indicating that better health-related quality of life was associated with decreased disease burden.

BACKGROUND: Treating anemia associated with chemotherapy and many cancers is often necessary. However, patient satisfaction with anemia treatment is limited by the lack of validated instruments. We developed and validated a new treatment-specific patient satisfaction instrument: the Patient Satisfaction Questionnaire for Anemia Treatment (PSQ-An). Treatment burden and overall satisfaction scales were designed for ease of use in clinical practice. METHODS: 312 cancer patients (141 breast, 69 gynecological, and 102 non-small cell lung) were targeted to complete the PSQ-An at 4 week intervals. Data from weeks 5 and 9 were analyzed. Patients also completed the MOS SF-36 Global Health assessment and questions concerning resources devoted to anemia treatment. Item reduction used endorsement rates, floor/ceiling effects, and item-item correlations. Factor analysis identified meaningful subscales. Test-retest reliability was assessed. Construct validity was tested, using Pearson's correlations, by comparing subscale scores to Global Health, hemoglobin levels, and resources devoted to anemia treatment. RESULTS: The overall response rate was 92.9% (264/284) at week 5. Most (84.2%) of the patients were female, and the mean (SD) age was 60.2 (+/- 11.8) years. Two distinct subscales were identified measuring treatment burden (7 items) and overall satisfaction (2 items). Test-retest reliability was examined (ICC: 0.45-0.67); both were internally consistent (alpha = 0.83). Both subscales exhibited convergent and divergent validity with independent measures of health. ANOVA results indicated that the PSQ-An Satisfaction subscale discriminated between 5 levels of MOS SF-36 Global Health (P = 0.006). CONCLUSION: The PSQ-An is a validated, treatment-specific instrument for measuring satisfaction with anemia treatment for cancer patients. PSQ-An subscales reflect the burden of injection anemia treatment on cancer patients and their assessment of the overall treatment value.

BACKGROUND: Treatment options for the management of rheumatoid arthritis (RA) have expanded from the traditional disease-modifying antirheumatic drugs (DMARDs) to include the biologic DMARDs that inhibit tumor necrosis factoralpha (TNF-a). OBJECTIVE: To assess the medical literature for studies of the economic value of biologic DMARDs, specifically the 3 TNF-a inhibitors (adalimumab, etanercept, and infliximab) used for the management of RA, compared with the traditional DMARDs such as sulfasalazine, antimalarials, penicillamine, gold, methotrexate, azathioprine, leflunomide, and cyclophosphamide. METHODS: A comprehensive search of the MEDLINE and HealthSTAR databases was conducted to identify cost-efficacy, cost-effectiveness, or cost-utility studies published in the English language (from 1966 through November 2004). The search terms and/or MeSH (medical subject headings) titles were cost-benefit analysis, rheumatoid arthritis, antirheumatic agents, antineoplastic and immunosuppressive agents. Studies were critically reviewed and quality was assessed using the Quality of Health Economic Studies instrument. Most studies evaluated the use of biologics among RA patients resistant to DMARDs. Studies were assessed with regard to comparators evaluated, measures of efficacy, perspectives, model duration, treatment duration, and discount rate. RESULTS: From 180 titles identified, 155 were excluded for the following reasons: 89 because they did not consider the drugs of interest, 15 because the population was not RA, 19 because of having the wrong drugs and population, 22 because they were review articles, and 10 because they were general articles. Twentyfive abstracts were accepted for further review. Of these, 13 abstracts were subsequently selected for full-text review. One of the authors identified a study not indexed in MEDLINE. Ultimately, 2 cost-effectiveness and 6 cost-utility studies were selected for this critical review. One study over 6 months reported that triple therapy with DMARDs (methotrexate-hydroxychloroquine-sulfasalazine) was cost effective for methotrexate-resistant patients, which is consistent with American College of Rheumatology (ACR) guidelines that support the use of triple therapy prior to biologics. The incremental cost-effectiveness ratio (ICER) was $1,500 per patient to achieve an ACR20 response for this triple therapy compared with no second-line agent. Overall, biologic therapies cost considerably more than traditional DMARDs but produced more quality-adjusted life-years (QALYs). Despite differences in design and assumptions, published economic models consistently reported ICERs <50,000 dollars per QALY gained for biologics compared with traditional DMARDs, although ICERs of >100,000 dollars were reported from sensitivity analyses. CONCLUSIONS: Clinical guidelines currently recommend the use of biologics as step therapy after failure of traditional DMARDs. Reported ICERs comparing biologics with traditional DMARDs are within a range that is comparable with other accepted medical interventions. The worth of the additional expenditure will ultimately be judged by formulary and policy decision makers because no maximum cost has been defined. Models can be used to inform decision makers, but they must be interpreted and applied carefully. More research is also needed to differentiate the relative economic value of the various biologic agents by therapeutic indication.

In an effort to assess the burden associated with psoriasis, the MEDLINE database and bibliographies of articles published from 1975 through 2004 were searched, emphasizing patients with moderate-to-severe disease, to summarize the current understanding on various aspects of disease burden. The clinical burden of psoriasis is both well documented and significant. The disease is debilitating: Sufficient disease severity interferes with patients' work and day-to-day living. Perhaps even more damaging is the psychosocial toll psoriasis exacts on the afflicted. Numerous studies document the extent of mental and emotional anguish, features not often revealed through objective measures. Successful treatment must focus on improving a patient's quality of life as well as reducing the clinical features of psoriasis. The economic burden is also significant, though far fewer studies of the associated indirect costs have been published in the literature.

BACKGROUND: Schizophrenia is one of the top 25 leading causes of disability worldwide in 2013. Despite its low prevalence, its health, social, and economic burden has been tremendous, not only for patients but also for families, caregivers, and the wider society. The magnitude of disease burden investigated in an economic burden study is an important source to policymakers in decision making. This study aims to systematically identify studies focusing on the economic burden of schizophrenia, describe the methods and data sources used, and summarize the findings of economic burden of schizophrenia. METHODS: A systematic review was performed for economic burden studies in schizophrenia using four electronic databases (Medline, EMBASE, PsycINFO, and EconLit) from inception to August 31, 2014. RESULTS: A total of 56 articles were included in this review. More than 80% of the studies were conducted in high-income countries. Most studies had undertaken a retrospective- and prevalence-based study design. The bottom-up approach was commonly employed to determine cost, while human capital method was used for indirect cost estimation. Database and literature were the most commonly used data sources in cost estimation in high-income countries, while chart review and interview were the main data sources in low and middle-income countries. Annual costs for the schizophrenia population in the country ranged from US$94 million to US$102 billion. Indirect costs contributed to 50%-85% of the total costs associated with schizophrenia. The economic burden of schizophrenia was estimated to range from 0.02% to 1.65% of the gross domestic product. CONCLUSION: The enormous economic burden in schizophrenia is suggestive of the inadequate provision of health care services to these patients. An informed decision is achievable with the increasing recognition among public and policymakers that schizophrenia is burdensome. This results in better resource allocation and the development of policy-oriented research for this highly disabling yet under-recognized mental health disease.
RESUMO
OBJECTIVE: To quantify the economic impact of premenstrual syndrome (PMS) on the employer. METHODS: Data were collected from 374 women aged 18-45 with regular menses. Direct costs were quantified using administrative claims of these patients and the Medicare Fee Schedule. Indirect costs were quantified by both self-reported days of work missed and lost productivity at work. Regression analyses were used to develop a model to project PMS-related direct and indirect costs. RESULTS: A total of 29.6% (n = 111) of the participants were diagnosed with PMS. A PMS diagnosis was associated with an average annual increase of $59 in direct costs (P < 0.026) and $4333 in indirect costs per patient (P < 0.0001) compared with patients without PMS. CONCLUSIONS: A PMS diagnosis correlated with a modest increase in direct medical costs and a large increase in indirect costs.

BACKGROUND: Studies show that subspecialists can provide better quality care than primary care physicians when working within their subspecialty for patients with some medical conditions. However, many subspecialists care for patients outside of their chosen subspecialty. The present study compared the quality of care provided by subspecialists practicing outside of their specialty, general internists, and subspecialists practicing within their specialty. METHODS: The severity-adjusted mortality rate and the severity-adjusted length of stay were used as indexes of quality of care. Data from 5112 hospital admissions (301 different physicians) for community-acquired pneumonia, acute myocardial infarction, congestive heart failure, or upper gastrointestinal hemorrhage at 6 hospitals in the greater Cleveland, Ohio, area were used in this study. The data were severity adjusted with the CHOICE Severity of Illness System. RESULTS: Subspecialists working outside of their subspecialty cared for 25% of hospitalized patients. When comparing patients cared for by subspecialists practicing outside of their subspecialty, severity-adjusted lengths of stay were longer for patients with congestive heart failure (23% longer; 95% confidence interval [CI], 15%-32%), upper gastrointestinal hemorrhage (22% longer; 95% CI, 7%-39%), and community-acquired pneumonia (14% longer; 95% CI, 5%-24%) than for patients cared for by subspecialists practicing within their subspecialty. Patients also had a slightly higher hospital mortality rate when cared for by subspecialists practicing outside of their specialty than by subspecialists practicing within their subspecialty (mortality rate odds ratio, 1.46; P =.047). In addition, patients cared for by subspecialists practicing outside of their subspecialty had longer lengths of stay, and prolongations of stay were observed for patients with congestive heart failure (16% longer; 95% CI, 8%-26%), upper gastrointestinal hemorrhage (15% longer; 95% CI, 2%-30%), and community-acquired pneumonia (18% longer; 95% CI, 9%-28%) than patients cared for by general internists. CONCLUSIONS: Subspecialists commonly care for patients outside of their subspecialty, despite the fact that their patients may have longer lengths of stay than those cared for by subspecialists practicing within their specialty or by general internists. In addition, such patients may have slightly higher mortality rates than those cared for by subspecialists practicing within their subspecialty.

OBJECTIVE: To evaluate the efficacy, safety, and impact on hospitalizations of long-acting injectable paliperidone palmitate (PP) treatment, in patients with recent-onset schizophrenia who had not responded satisfactorily to oral antipsychotics. METHODS: In this 18-month, open-label, Phase-IIIb study from Asia-Pacific region, patients (18-50 years) with recent-onset (≤5 years) schizophrenia unsatisfactorily treated with previous oral antipsychotics were initiated on PP 150 mg eq on day 1, 100 mg eq on day 8, followed by flexible once monthly maintenance doses of 50-150 mg eq. The number and duration of hospitalizations were compared using a mirror analysis method between two periods: retrospective (12 months before PP initiation) and prospective (12 and 18 months after PP treatment) periods. RESULTS: A total of 303 out of 521 (58%) patients (mean age, 28.7 years; 65.5% men, 92.5% Asian) completed the study. Positive and Negative Syndrome Scale (PANSS) total score improved significantly from baseline to month 18 (mean [standard deviation, SD] change: -11.3 [21.38], P<0.0001, primary endpoint). Subgroup analysis revealed greater improvements among patients with worse disease severity at baseline: PANSS ≥70 versus <70 (mean [SD] change: -23.1 [24.62] vs -4.7 [15.98], P<0.0001 each). Secondary efficacy endpoints such as Clinical Global Impression of Schizophrenia (CGI-SCH), Medication Satisfaction Questionnaire (MSQ) scores showed significant improvements (P<0.0001) from baseline; 33.3% patients achieved symptom remission. In mirror analyses set (N=474), PP significantly (P<0.0001) reduced mean number of hospitalization days/person/year (12-month: 74.3 vs 19.7; 18-month: 74.3 vs 18.9) as well as percentage of patients requiring hospitalization in past 12 months (12-month: 39.7% vs 24.6%; 18-month: 39.7% vs 25%), and PP treatment increased the proportion of patients not requiring hospitalization (12-month: 60.3% vs 75.4%; 18-month: 60.3% vs 75%) from retrospective to prospective period. Adverse events (≥15%) were extrapyramidal symptoms-related (31.3%), injection-site pain (18.6%), and insomnia (15.2%). CONCLUSION: PP was efficacious and generally tolerable with significant reductions observed in both number of hospitalizations and days spent in hospital.
RESUMO
BACKGROUND: Schizophrenia results in substantial health care utilization costs. Much of these costs can be attributed to health care use resulting from nonadherence to treatment, relapse, and hospitalization. AIMS OF THE STUDY: The objective of this research is to further estimate the health care resource utilization costs of patients with schizophrenia in the People's Republic of China, Korea, and Malaysia with a specific focus on the reduction in hospitalization costs associated with the use of long-acting, injectable paliperidone palmitate (PP) relative to alternative treatment medications. METHODS: The study focuses exclusively on the estimated reduction in hospitalization days following treatment with PP and the potential associated cost savings. Cost analysis was done using a payer's perspective and only includes direct health care costs associated with hospitalization. Localized cost data were taken from published sources, and health care utilization was estimated based on a clinical study conducted in countries in the Asia-Pacific region. People's Republic of China, Korea, and Malaysia had the highest number of patients enrolled in the clinical study, and thus were chosen for this research. Analysis looked at 12-month and 18-month periods following initial treatment with PP relative to a retrospective 12-month period utilizing alternative treatment medications. RESULTS: Results suggest that reductions in hospital utilization cost over 12 months may occur through the use of PP relative to alternatives-ranging from $1,991 for the People's Republic of China to $6,698 for Korea and $6,716 for Malaysia. CONCLUSION: Given the substantial costs associated with the treatment of schizophrenia both worldwide and in Asia, it is important to fully understand the costs and outcomes associated with various treatment options. In this research, we have specifically analyzed the direct health care cost savings associated with hospital utilization for patients taking PP relative to alternative treatment methods. The results suggest that reductions in hospital utilization cost were associated with PP treatment, likely largely due to increased adherence to treatment.
RESUMO
This trial was conducted to evaluate the safety and efficacy of the H4 R-antagonist JNJ-39758979 in adult Japanese patients with moderate atopic dermatitis (AD). Eligible patients were randomly assigned to JNJ-39758979 300 mg, 100 mg or placebo once daily for 6 weeks in this phase 2a, double-blind, multicenter, placebo-controlled study. Primary efficacy was assessed via week-6 Eczema Area and Severity Index (EASI) scores. Secondary efficacy assessments included Investigator's Global Assessment (IGA) and patient-reported outcome (PRO) pruritus assessments (Pruritus Categorical Response Scale [PCRS], Pruritus Numeric Rating Scales [PNRS], Pruritus Interference Numeric Rating Scale [PINRS] and Subject's Global Impressions of Change in Pruritus [SGICP]). Eighty-eight of 105 planned patients were randomized before the study was stopped and unblinded for safety reasons. The study did not meet the primary end-point. However, numerical improvements (i.e. decreases) in median EASI were observed with JNJ-39758979 100 mg (-3.7) and 300 mg (-3.0) versus placebo (-1.3) at week 6. Nominally significant improvements across PRO PCRS, PNRS and SGICP assessments were consistently observed, particularly with JNJ-39758979 300 mg. Safety, including adverse events (AE), was comparable between JNJ-39758979 and placebo with the exception of two patients (both receiving JNJ-39758979 300 mg) with serious AE of neutropenia, leading to premature study discontinuation. No deaths were reported. Except for neutropenia, no clinically relevant changes in laboratory values were observed. Although not conclusive, findings suggest H4 R-antagonism may be beneficial for AD, particularly in controlling pruritus. JNJ-39758979 appears to be associated with drug-induced agranulocytosis, likely an off-target effect.

OBJECTIVE: To examine from the health care services payer perspective the economic consequences of contraceptives available to women in the United States. METHODS: A Markov model was constructed to compare effectiveness and costs among nine contraceptive methods (including 3-month injectable, oral contraceptives, intrauterine device (IUD), intrauterine system (IUS), barrier methods and surgical methods). Primary health states included initial/continued use, method failure and method discontinuation with transitions every year for 5 years. Plan disenrollment was also incorporated in the model. Estimates for probabilities of events, resource used, and costs for the base-case were derived from a comprehensive literature review, average wholesale drug prices, the 2000 Medicare Reimbursement Fee Schedule and MEDSTAT's 2000 DRG Guide, in conjunction with expert opinion. Sensitivity analyses were performed on all variables. RESULTS: Aside from vasectomy, which was outside the scope of this study, the most effective methods were tubal ligation, levonorgestrel (LNG)-20 IUS and copper T 380A IUD. The least expensive methods (accounting for all costs) were LNG-20 IUS, copper T 380A IUD and 3-month injectable; the 5-year cost/person were $1646, $1678 and $2195, respectively. CONCLUSION: From a third-party payer perspective, LNG-20 IUS and copper T 380A IUD dominated all reviewed methods, except for tubal ligation. However, the small increase in contraceptive efficacy with tubal ligation has a high cost. IUD and IUS device costs have a significant impact on the relative cost-effectiveness of these two methods.
