Effectiveness of antidementia drugs in delaying Alzheimer's disease progression

Abstract

BACKGROUND: Randomized controlled trials (RCTs) provide safety and efficacy data for regulatory approval of antidementia drugs, but offer limited data regarding real-world effectiveness. Long-term observational controlled studies (LTOCs) extend our understanding by providing longitudinal data across multiple stages of Alzheimer's disease (AD). METHODS: Comparisons of strengths, limitations, evidence level, and results for monotherapy (cholinesterase inhibitors) and combination therapy (cholinesterase inhibitors + memantine) in RCTs versus LTOCs were made. RESULTS: Similar to RCTs, LTOCs have shown that both monotherapy and combination therapy are associated with slower cognitive and functional decline. Combination therapy is associated with better cognitive outcomes and greater delays in time to nursing home admission versus monotherapy or no treatment. Persistent antidementia drug treatment is associated with slower decline in cognition, daily function, and global severity, even in patients with advanced disease. CONCLUSIONS: LTOCs provide complementary evidence regarding effectiveness of antidementia therapy over many years, a time course relevant to AD management. These findings also provide compelling arguments in favor of using LTOCs to estimate effectiveness, risk-benefit, and costs of AD treatments.

  • Anti-AD therapies, whether as cholinesterase inhibitor or memantine monotherapy or as add-on dual combination therapy, have demonstrated short-term and long-term benefits to reduce decline in cognition and function.

    “A pharmacologic foundation of anti-AD therapies, whether with a ChEI or memantine monotherapy, or, ultimately, combined together as add-on dual combination therapy, most often as memantine added on to stable background ChEI treatment, have demonstrated benefits in the short-term and long-term to reduce decline in cognition and function”

  • In more than 40 short-term randomized controlled trials using placebos over 24 to 52 weeks and in meta-analyses of randomized controlled trials, all 3 cholinesterase inhibitors have demonstrated small to medium effect size treatment benefits at the subject-group level in improving, stabilizing, or delaying decline in cognition, activities of daily living, and global status, and in ameliorating BPS

    “In more than 40 short-term randomized controlled trials (RCTs) using placebos over 24 to 52 weeks investigating efficacy, and in meta-analyses of RCTs, all 3 ChEIs have demonstrated small to medium effect size treatment benefits at the sibject-group level in terms of improving, stabilizing, or delaying decline in cognition, ADL, and global status, and in ameliorating BPSD and caregiver burden.35,”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
