No effect of one-year treatment with indomethacin on Alzheimer's disease progression: a randomized controlled trial.

ABSTRACT: The objective of this study was to determine whether treatment with the nonselective nonsteroidal anti-inflammatory drug (NSAID) indomethacin slows cognitive decline in patients with Alzheimer's disease (AD).This double-blind, randomized, placebo-controlled trial was conducted between May 2000 and September 2005 in two hospitals in the Netherlands. 51 patients with mild to moderate AD were enrolled into the study. Patients received 100 mg indomethacin or placebo daily for 12 months. Additionally, all patients received omeprazole. The primary outcome measure was the change from baseline after one year of treatment on the cognitive subscale of the AD Assessment Scale (ADAS-cog). Secondary outcome measures included the Mini-Mental State Examination, the Clinician's Interview Based Impression of Change with caregiver input, the noncognitive subscale of the ADAS, the Neuropsychiatric Inventory, and the Interview for Deterioration in Daily life in Dementia. Considerable recruitment problems of participants were encountered, leading to an underpowered study. In the placebo group, 19 out of 25 patients completed the study, and 19 out of 26 patients in the indomethacin group. The deterioration on the ADAS-cog was less in the indomethacin group (7.8+/-7.6), than in the placebo group (9.3+/-10.0). This difference (1.5 points; CI -4.5-7.5) was not statistically significant, and neither were any of the secondary outcome measures.The results of this study are inconclusive with respect to the hypothesis that indomethacin slows the progression of AD.

Project description:BackgroundOur goal was to investigate the role of physical exercise to protect brain health as we age, including the potential to mitigate Alzheimer's-related pathology. We assessed the effect of 52 weeks of a supervised aerobic exercise program on amyloid accumulation, cognitive performance, and brain volume in cognitively normal older adults with elevated and sub-threshold levels of cerebral amyloid as measured by amyloid PET imaging.Methods and findingsThis 52-week randomized controlled trial compared the effects of 150 minutes per week of aerobic exercise vs. education control intervention. A total of 117 underactive older adults (mean age 72.9 [7.7]) without evidence of cognitive impairment, with elevated (n = 79) or subthreshold (n = 38) levels of cerebral amyloid were randomized, and 110 participants completed the study. Exercise was conducted with supervision and monitoring by trained exercise specialists. We conducted 18F-AV45 PET imaging of cerebral amyloid and anatomical MRI for whole brain and hippocampal volume at baseline and Week 52 follow-up to index brain health. Neuropsychological tests were conducted at baseline, Week 26, and Week 52 to assess executive function, verbal memory, and visuospatial cognitive domains. Cardiorespiratory fitness testing was performed at baseline and Week 52 to assess response to exercise. The aerobic exercise group significantly improved cardiorespiratory fitness (11% vs. 1% in the control group) but there were no differences in change measures of amyloid, brain volume, or cognitive performance compared to control.ConclusionsAerobic exercise was not associated with reduced amyloid accumulation in cognitively normal older adults with cerebral amyloid. In spite of strong systemic cardiorespiratory effects of the intervention, the observed lack of cognitive or brain structure benefits suggests brain benefits of exercise reported in other studies are likely to be related to non-amyloid effects.Trial registrationNCT02000583; ClinicalTrials.gov.

Project description:ObjectiveChildhood-onset depression is associated with increased risk of recurrent depression and high morbidity extending into adolescence and adulthood. This multisite randomized controlled trial evaluated two active psychosocial treatments for childhood depression: family-focused treatment for childhood depression (FFT-CD) and individual supportive psychotherapy (IP). Aims were to describe effects through 52 weeks postrandomization on measures of depression, functioning, nondepressive symptoms, and harm events.MethodsChildren meeting criteria for depressive disorders (N = 134) were randomly assigned to 15 sessions of FFT-CD or IP and evaluated at mid-treatment for depressive symptoms and fully at roughly 16 weeks (after acute treatment), 32 weeks, and 52 weeks/one year. See clinicaltrials.gov: NCT01159041.ResultsAnalyses using generalized linear mixed models confirmed the previously reported FFT-CD advantage on rates of acute depression response (≥50% Children's Depression Rating Scale reduction). Improvements in depression and other outcomes were most rapid during the acute treatment period, and leveled off between weeks 16 and 52, with a corresponding attenuation of observed group differences, although both groups showed improved depression and functioning over 52 weeks. Survival analyses indicated that most children recovered from their index depressive episodes by week 52: estimated 76% FFT-CD, 77% IP. However, by the week 52 assessment, one FFT-CD child and six IP children had suffered recurrent depressive episodes. Four children attempted suicide, all in the IP group. Other indicators of possible harm were relatively evenly distributed across groups.ConclusionsResults indicate a quicker depression response in FFT-CD and hint at greater protection from recurrence and suicide attempts. However, outcomes were similar for both active treatments by week 52/one year. Although community care received after acute treatment may have influenced results, findings suggest the value of a more extended/chronic disease model that includes monitoring and guidance regarding optimal interventions when signs of depression-risk emerge.

Project description:In phase-3 clinical trials, the interleukin (IL-1) blocker, rilonacept (IL-1 Trap), demonstrated efficacy for gout flare prevention during initiation of urate-lowering therapy. This trial evaluated rilonacept added to a standard-of-care, indomethacin, for treatment of acute gout flares.Adults, aged 18-70 years, with gout presenting within 48 hours of flare onset and having at least moderate pain as well as swelling and tenderness in the index joint were randomized to subcutaneous (SC) rilonacept 320 mg at baseline plus oral indomethacin 50 mg TID for 3 days followed by 25 mg TID for up to 9 days (n = 74); SC placebo at baseline plus oral indomethacin as above (n=76); or SC rilonacept 320 mg at baseline plus oral placebo (n=75). The primary efficacy endpoint was change in pain in the index joint (patient-reported using a Likert scale (0=none; 4=extreme)) from baseline to the average of values at 24, 48 and 72 hours (composite time point) for rilonacept plus indomethacin versus indomethacin alone. Comparison of rilonacept monotherapy with indomethacin monotherapy was dependent on demonstration of significance for the primary endpoint. Safety evaluation included clinical laboratory and adverse event (AE) assessments.Patient characteristics were comparable among the groups; the population was predominantly male (94.1%), white (75.7%), with mean±SD age of 50.3±10.6 years. All treatment groups reported within-group pain reductions from baseline (P<0.0001). Although primary endpoint pain reduction was greater with rilonacept plus indomethacin (-1.55±0.92) relative to indomethacin alone (-1.40±0.96), the difference was not statistically significant (P=0.33), so formal comparison between monotherapy groups was not performed. Pain reduction over the 72-hour period with rilonacept alone (-0.69±0.97) was less than that in the other groups, but pain reduction was similar among groups at 72 hours. Treatment with rilonacept was well-tolerated with no reported serious AEs related to rilonacept. Across all groups, the most frequent AEs were headache and dizziness.Although generally well-tolerated, rilonacept in combination with indomethacin and rilonacept alone did not provide additional pain relief over 72 hours relative to indomethacin alone in patients with acute gout flare.ClinicalTrials.gov registration number NCT00855920.
