    Objective. To compare the efficacy and tolerability of tofacitinib, an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), as monotherapy and combined with disease-modifying antirheumatic drugs (DMARDs) versus biological DMARDs (bDMARDs) and other novel DMARDs for second-line moderate-to-severe rheumatoid arthritis (RA) patients by means of a systematic literature review (SLR) and network meta-analysis (NMA). Methods. MEDLINE®, EMBASE®, and Cochrane Central Register of Controlled Trials were searched to identify randomized clinical trials (RCTs) published between 1990 and March 2015. Efficacy data based on American College of Rheumatology (ACR) response criteria, improvements in the Health Assessment Questionnaire Disability Index (HAQ-DI) at 6 months, and discontinuation rates due to adverse events were analyzed by means of Bayesian NMAs. Results. 45 RCTs were identified, the majority of which demonstrated a low risk of bias. Tofacitinib 5 mg twice daily (BID) and 10 mg BID monotherapy exhibited comparable efficacy and discontinuation rates due to adverse events versus other monotherapies. Tofacitinib 5 mg BID and 10 mg BID + DMARDs or methotrexate (MTX) were mostly comparable to other combination therapies in terms of efficacy and discontinuation due to adverse events. Conclusion. In most cases, tofacitinib had similar efficacy and discontinuation rates due to adverse events compared to biologic DMARDs

    INTRODUCTION: No published studies exist comparing the effectiveness of tofacitinib with other advanced therapies for the treatment of rheumatoid arthritis (RA) in real-world clinical practice. Here, we report differences in effectiveness of tofacitinib compared with standard of care, tumor necrosis factor inhibitors (TNFi), with or without concomitant methotrexate (MTX), using US Corrona registry data. METHODS: This observational cohort study included RA patients receiving tofacitinib (from 6 November 2012; N = 558) or TNFi (from 1 November 2001; N = 8014) with or without MTX until 31 July 2016. Efficacy outcomes at 6 months included modified American College of Rheumatology 20% responses, Clinical Disease Activity Index (CDAI) and Pain. Outcomes were compared between patients receiving TNFi and tofacitinib with or without MTX and by line of therapy. Outcomes within therapy lines were compared using propensity-score matching; between-group differences were estimated using mixed-effects regression models. RESULTS: Patients receiving tofacitinib had longer RA duration and a greater proportion had previously received biologics than those receiving TNFi; other baseline characteristics were comparable. In patients receiving second- and third-line TNFi therapy, CDAI low disease activity/remission response rates were significantly better with concomitant MTX. Too few patients received tofacitinib as second line for meaningful assessment. No significant differences were observed in outcomes between tofacitinib as monotherapy and tofacitinib with concomitant MTX. CONCLUSIONS: In clinical practice, TNFi efficacy is improved with concomitant MTX in the second and third line. In the third/fourth line, patients are likely to achieve similar efficacy with tofacitinib monotherapy, or TNFi or tofacitinib in combination with MTX. FUNDING: Pfizer Inc

    Tofacitinib versus methotrexate in rheumatoid arthritis

    Background : Methotrexate is the most frequently used first-line antirheumatic drug. We report the findings of a phase 3 study of monotherapy with tofacitinib, an oral Janus kinase inhibitor, as compared with methotrexate monotherapy in patients with rheumatoid arthritis who had not previously received methotrexate or therapeutic doses of methotrexate. Methods : We randomly assigned 958 patients to receive 5 mg or 10 mg of tofacitinib twice daily or methotrexate at a dose that was incrementally increased to 20 mg per week over 8 weeks; 956 patients received a study drug. The coprimary end points at month 6 were the mean change from baseline in the van der Heijde modified total Sharp score (which ranges from 0 to 448, with higher scores indicating greater structural joint damage) and the proportion of patients with an American College of Rheumatology (ACR) 70 response (>= 70% reduction in the number of both tender and swollen joints and >= 70% improvement in three of five other criteria: the patient's assessment of pain, level of disability, C-reactive protein level or erythrocyte sedimentation rate, global assessment of disease by the patient, and global assessment of disease by the physician). Results : Mean changes in the modified total Sharp score from baseline to month 6 were significantly smaller in the tofacitinib groups than in the methotrexate group, but changes were modest in all three groups (0.2 points in the 5-mg tofacitinib group and <0.1 point in the 10-mg tofacitinib group, as compared with 0.8 points in the methotrexate group [ P<0.001 for both comparisons]). Among the patients receiving tofacitinib, 25.5% in the 5-mg group and 37.7% in the 10-mg group had an ACR 70 response at month 6, as compared with 12.0% of patients in the methotrexate group (P<0.001 for both comparisons). Herpes zoster developed in 31 of 770 patients who received tofacitinib (4.0%) and in 2 of 186 patients who received methotrexate (1.1%). Confirmed cases of cancer (including three cases of lymphoma) developed in 5 patients who received tofacitinib and in 1 patient who received methotrexate. Tofacitinib was associated with increases in creatinine levels and in low-density and high-density lipoprotein cholesterol levels. Conclusions : In patients who had not previously received methotrexate or therapeutic doses of methotrexate, tofacitinib monotherapy was superior to methotrexate in reducing signs and symptoms of rheumatoid arthritis and inhibiting the progression of structural joint damage. The benefits of tofacitinib need to be considered in the context of the risks of adverse events

    Cost-Effectiveness Analysis of Treatments for Premenstrual Dysphoric Disorder

    Background: Premenstrual syndrome (PMS) is reported to affect between 13% and 31% of women. Between 3% and 8% of women are reported to meet criteria for the more severe form of PMS, premenstrual dysphoric disorder (PMDD). Although PMDD has received increased attention in recent years, the cost effectiveness of treatments for PMDD remains unknown. Abstract: Objective: To evaluate the cost effectiveness of the four medications with a US FDA-approved indication for PMDD: fluoxetine, sertraline, paroxetine and drospirenone plus ethinyl estradiol (DRSP/EE). Abstract: Methods: A decision-analytic model was used to evaluate both direct costs (medication and physician visits) and clinical outcomes (treatment success, failure and discontinuation). Medication costs were based on average wholesale prices of branded products; physician visit costs were obtained from a claims database study of PMDD patients and the Agency for Healthcare Research and Quality. Clinical outcome probabilities were derived from published clinical trials in PMDD. The incremental cost-effectiveness ratio (ICER) was calculated using the difference in costs and percentage of successfully treated patients at 6 months. Deterministic and probabilistic sensitivity analyses were used to assess the impact of uncertainty in parameter estimates. Threshold values where a change in the cost-effective strategy occurred were identified using a net benefit framework. Abstract: Results: Starting therapy with DRSP/EE dominated both sertraline and paroxetine, but not fluoxetine. The estimated ICER of initiating treatment with fluoxetine relative to DRSP/EE was &dollar;US4385 per treatment success (year 2007 values). Cost-effectiveness acceptability curves revealed that for ceiling ratios ≥&dollar;US3450 per treatment success, fluoxetine had the highest probability (≥0.37) of being the most cost-effective treatment, relative to the other options. The cost-effectiveness acceptability frontier further indicated that DRSP/EE remained the option with the highest expected net monetary benefit for ceiling values ≤&dollar;US3900 per treatment success. Abstract: Conclusion: These analyses suggest that initiating therapy with DRSP/EE may be a cost-effective option in the treatment of PMDD.Cost-effectiveness, Ethinylestradiol/drospirenone, therapeutic use, Fluoxetine, therapeutic use, Paroxetine, therapeutic use, Premenstrual-dysphoric-disorder, treatment, Sertraline, therapeutic use
