Disease-modifying drugs for multiple sclerosis Page 2 of 120 Final Report Update 1 Drug Effectiveness Review Project STRUCTURED ABSTRACT Purpose We compared the effectiveness and safety of disease-modifying drugs for the treatment of ® ® ® multiple sclerosis: Glatiramer acetate (Copaxone ), interferon beta-1a (Avonex , Rebif ), ® ® ® interferon beta-1b (Betaseron , Extavia ), mitoxantrone (Novantrone ), and natalizumab ® (Tysabri ). Data Sources ® We searched Ovid MEDLINE and the Cochrane Library and the Database of Abstracts of Reviews of Effects through December 2009. For additional data we also hand searched reference lists, government web sites and dossiers submitted by pharmaceutical companies. Review Methods Study selection, data abstraction, validity assessment, grading the strength of the evidence, and data synthesis were all carried out according to standard Drug Effectiveness Review Project review methods. Results In patients with relapsing remitting multiple sclerosis, little difference in relapse outcomes were ® ® found between interferon beta-1a SC (Rebif ) and interferon beta-1b (Betaseron ), while ® ® interferon beta-1a IM (Avonex ) was less effective than interferon beta-1a SC (Rebif ) and ® interferon beta-1b (Betaseron ) based on 4 fair-quality head-to-head trials. Direct evidence from 5 fair-quality head-to-head trials was conflicting on disease progression outcomes between the interferons. Pooled analysis of direct and indirect trial data found no difference between the ® interferons on changes in disability and no difference between interferon beta-1a SC (Rebif ) ® and interferon beta-1a IM (Avonex ) on disease progression but did find interferon beta-1b ® ® (Betaseron ) to be superior to interferon beta-1a IM (Avonex ) on disease progression (relative risk, 0. There was no difference in relapse or disease progression ® ® between glatiramer and interferon beta-1a SC (Rebif ) or interferon beta-1b (Betaseron ) based on 2 head-to-head trials. Evidence is insufficient to make any judgments regarding effectiveness in primary progressive or secondary progressive multiple sclerosis. Evidence suggested that all 3 interferon beta-1 products and glatiramer reduced the probability of converting from clinically isolated syndrome to clinically definite multiple sclerosis over 2 to 5 year periods. Evidence for interferon beta-1b SC ® ® (Betaseron ) and interferon beta-1a SC (Rebif ) indicated that consistent positive neutralizing antibody status with high titer increased relapse rates, by one-half to two-thirds, during longer Disease-modifying drugs for multiple sclerosis Page 3 of 120 Final Report Update 1 Drug Effectiveness Review Project periods of follow-up. This difference was not seen with follow-up of 2 years or less, and there was inadequate evidence to conclude that there is an impact on disease progression. No difference was found in withdrawal rates among beta interferons in head-to-head trials. Transaminase elevations were common with all beta interferon products, with little difference in rates of occurrence. There was a lower rate of depression in patients taking ® interferon beta-1a (Rebif ) compared with the other interferons based on limited trial data. Interferon beta-1b SC (Avonex ) was associated with ® the lowest rates of injection site reactions whereas interferon beta-1b SC (Betaseron ) and ® interferon beta-1b SC (Rebif ) had similar rates. Significant long-term concerns included progressive multifocal leukoencephalopathy in patients receiving natalizumab >12 months, lipoatrophy with prolonged use of glatiramer, and permanent amenorrhea in older women receiving higher total dose of mitoxantrone. There was some evidence that response to beta interferons and glatiramer differs in men and women, but there was no evidence that this difference favors one product over another. Evidence is insufficient to make conclusions about the safety of these drugs in pregnancy. A post ® hoc subgroup analysis of a head-to-head trial of interferon beta-1a products (Avonex and ® Rebif ) found that African-American patients experienced more exacerbations and were less likely to be exacerbation-free compared with white patients over the course of the study.

Use of plasma should take into consideration the dilution factor that may be produced because of the anticoagulant cheap prinivil 10mg amex. Isotype of aCL and anti- 2GPI IgG and IgM isotypes are recommended for both aCL and anti- 2GPI prinivil 10mg sale. Anti- 2GPI: 2GPI of human origin should be used on a negatively charged (“high” binding or gamma-irradiated) plate buy 5 mg prinivil overnight delivery. Quantitation of results The test signal is converted into antibody units derived from the calibration curve. Anti- 2GPI are expressed in arbitrary units; universal units of measurement are not available. Development/establishment of international/universal units of measurement is recommended. Standards Manufacturers and test users are strongly encouraged to select a reliable standard to prepare secondary calibrators (polyclonal or monoclonal). The proposed secondary calibrators should be compared and validated against the primary standard using published and accepted procedures. Selected groups of actual patient sera should be used if possible to further establish the extent of agreement in the assay/test system. Most importantly, the production and the quality control of the standards should be subjected to FDA Good Manufacturing Practices guidelines or an equivalent quality assurance program. A record of traceability from the recommended standards to any secondary calibrators is required. Calibration curves Multipoint calibration and use of statistically correct fitting and calculation methods are required. The calibration curve should be rejected if the correlation coefficient between assay readings and expected values of the calibrators is 0. Precision CV of manually performed ELISAs should be 20%, preferably 15%. Positive/negative controls Incorporation of at least 1 “external” positive control in every run to monitor interassay variation is recommended. Similarly, a “negative” control with values below the cutoff of the assay should be used in each run. A run should be rejected if the result with either the positive or the negative control falls out of the established range. Singlet/duplicate It is recommended to do duplicate testing, especially when inter-run and intra-run imprecision determined for a quality measurements control sample is 10%. If this is not feasible, manufacturers’cutoffs may be acceptable if local measurements on 20 or more healthy subjects yields similar results. Reporting of results Given the variability in assay methods, semiquantitative reporting is difficult to define. Each test result above the 99th percentile cutoff should be regarded as positive and reported quantitatively. Imprecision of the method should be considered, especially for results around the cutoff. Manufacturers should disclose information based on evidence derived from clinical studies that may assist with the interpretation of results.

A very short trial comparing darifenacin with oxybutynin reported 3 treatment-related 26 withdrawals due to adverse events overall buy cheap prinivil 5mg on line. The study discount prinivil 2.5 mg line, designed as a crossover order prinivil 5mg fast delivery, included a total of only 65 participants, who were divided into 3 cohorts; not all members of each cohort participated in all of the measurements. The STAR trial, comparing the difference between solifenacin (5 mg or 10 mg) and tolterodine extended-release (4 mg) reported withdrawals due to adverse events for all patients 28 receiving solifenacin (3. Our statistical analysis found that this difference was not significant. A post hoc analysis comparing solely the Overactive bladder Page 35 of 73 Final Report Update 4 Drug Effectiveness Review Project 5 mg dose of solifenacin (the “no-dose-increase” subgroup) with tolterodine extended-release found that over 12 weeks both groups had a comparable incidence of withdrawal due to adverse 106 events (1. These differences were not statistically significant. Is there a difference in adverse events between long-acting and short-acting formulations? Immediate-release compared with extended-release tolterodine Short-term studies In a 12-week head-to-head placebo-controlled trial of extended-release and immediate release formulations of tolterodine, rate of dry mouth was 23% for extended-release tolterodine, 30% for immediate-release, and 8% for placebo. Rate of constipation was 6% for extended-release, 7% 46 for immediate-release, and 4% for placebo. Withdrawal due to adverse event was almost identical: for extended-release, 5. There were 2 additional short-term observational trials, one each measuring tolerability of 111, 116 tolterodine immediate-release and extended-release. All observational trials are summarized in Evidence Table 8. The study of varying doses of the short-acting formulation reported 4. It is not entirely clear how adverse events were assessed. In the trial of tolterodine extended-release 4 mg, authors reported that16% of patients had dry mouth and 8% 111 withdrew from the study due to adverse events. Long-term studies We found 5 longer-term observational studies, 3 for tolterodine extended-release and 2 for the 55, 113, 114, 121, 126 immediate-release formulation. All trials reported rates of dry mouth ranging from 7. The withdrawal rates due to adverse events were more consistent, ranging from 2. Overall rates of adverse events were inconsistently reported and were spread from 10% to 77%, thus not useful for conclusions. It is essential to note that trial designs varied from frequent provider visits and elicitation of adverse events to phone or postal surveys of experience with drugs; design could have substantially influenced the outcome of reported adverse events. Immediate-release compared with extended-release oxybutynin Short-term studies 22, 24, There were 4 studies comparing long-acting with short-acting formulations of oxybutynin. Two of these trials have an unclear duration Overactive bladder Page 36 of 73 Final Report Update 4 Drug Effectiveness Review Project 22, 47 of follow-up but report significantly more dry mouth with oxybutynin immediate-release 22 than with oxybutynin extended-release (48% compared with 59%; P=0. Adverse event rates for extended-release and immediate-release formulations were 28% and 17% for blurred vision, 28% and 38% for dizziness, and 30% and 31% for constipation. Rate of withdrawal due to adverse event was 3% for extended-release and 6% for immediate-release in one trial and 4% for both groups in the other trial, overall very low. Without reporting statistical significance, another 4-week trial found that dry mouth was somewhat more frequent with oxybutynin immediate-release (72%) than extended-release (68%). For dry mouth considered moderate-to-severe, the incidence was 45% with immediate- 24 release oxybutynin and 38% with extended-release. Withdrawals due to adverse events were similar between formulations (immediate-release, 20%; extended-release, 17%). Another 4 week trial did not find higher rates of dry mouth in the immediate-release group (17%) than the extended-release group (23%); however, overall adverse events were higher for oxybutynin immediate-release (67%) than extended-release (55%). Statistical significance was not reported 25 for these comparisons. It is important to note that this trial included a run-in phase to establish tolerability, during which patients with adverse events were excluded. All of the above oxybutynin immediate-release compared with extended-release studies included some type of dose titration for both long- and short-acting formulations, which may have affected the adverse occurrences and made it difficult to make any conclusions about better tolerability. We found a 12-week observational trial of various doses of oxybutynin extended-release 118 that reported dry mouth in 59% of patient and withdrawal due to adverse event by 8%. Long-term studies There was only 1 longer-term study of oxybutynin immediate-release. No details of adverse events were contained, but an overall adverse event rate was reported as 34. Although the longest observational trial, it was administered as a single phone or postal questionnaire 2 years after baseline, limiting its value for conclusions. Are there subgroups of patients based on demographics (age, racial groups, gender), other medications, or comorbidities for which one anticholinergic incontinence drug is more effective or is associated with fewer adverse effects? The included studies generally enrolled ambulatory populations in the 50 to 60 year-old age range (mean), with more women than men. Age No head-to-head or observational studies conducted in long-term care facilities met inclusion criteria. A placebo-controlled study of oxybutynin added to a program of prompted voiding in a long-term facility found a statistically significant reduction in incontinence episodes in the 128 oxybutynin group (-2. A 12-week, randomized, 82 placebo-controlled trial found no significant difference in efficacy, safety, or tolerability Overactive bladder Page 37 of 73 Final Report Update 4 Drug Effectiveness Review Project between younger (<65 years) and older (≥65 years) women taking tolterodine extended-release 4 mg. Two studies examined effects of darifenacin in older adults with overactive bladder syndrome: a pooled analysis of data from the subgroups of patients >65 years old in 3 placebo- 129 controlled trials and an open-label extension study of patients >65 years from 2 of these 130 trials. Patients enrolled in the trials (pooled N=317, mean age 72 years) were highly functioning, ambulatory adults, although with numerous comorbidities. The difference in the median change in the number of incontinence episodes per week was statistically significantly greater with darifenacin 7. While statistical analyses were not performed, in darifenacin 7. The incidences of dry mouth, constipation, and dyspepsia were highest in the 15 mg group but cardiovascular and central nervous system adverse events were rare in all groups. From 2 of these trials, 217 patients entered a 2-year extension study where the dose was started at 7. Similarly, post hoc analyses of patients from 4 placebo-controlled trials (N=1045) and an extension study (N=509) of solifenacin 5 mg or 10 mg daily were done to examine effects in 131 patients >65 years old. The difference in the median change in the number of incontinence episodes per week compared with placebo was – 2. In this analysis, the incidence of dry mouth was also greater in the drug groups: 14% with 5 mg daily, 32% with 10 mg daily, and 4.
