Imagine you’re a curious detective, investigating the effects of a powerful new drug called lecanemab on patients with Alzheimer’s disease (AD). You gather all the evidence from randomized controlled trials and piece them together like a puzzle. The results? Lecanemab shows promise in stabilizing or slowing down cognitive decline in patients with early AD. It not only helps preserve cognition, function, and behavior but also carries a low risk of adverse events. However, the actual clinical significance of these findings is yet to be fully established. This review leaves us with an intriguing question: can lecanemab unlock new possibilities for effectively treating Alzheimer’s? To dive deeper into the research and understand the potential impact of lecanemab on patients’ lives, check out the full article!
ObjectiveWe performed a systematic review and meta-analysis of the cognitive effectiveness and safety of lecanemab on subjects with Alzheimer’s disease (AD).MethodsWe screened the literature published before February 2023 in PubMed, Embase, Web of Science, and Cochrane that were searched for randomized controlled trials testing lecanemab for the treatment of cognitive decline in patients with MCI or AD. Outcomes measured were CDR Sum of Boxes (CDR-SB), Alzheimer’s Disease Composite Score (ADCOMS), AD Assessment Scale–Cognitive Subscale (ADAS-Cog), Clinical Dementia Rating (CDR), amyloid PET Standardized Uptake Volume Ratio (SUVr), amyloid burden on PET, and risks for adverse events.ResultsA total of four randomized controlled trials were included, involving 3,108 AD patients (1,695 lecanemab groups and 1,413 placebo groups) to synthesize evidence. Baseline characteristics of the two groups were similar in all outcomes except that ApoE 4 status and higher MMSE score were observed in the lecanemab group. It is reported that lecanemab was beneficial to stabilize or slow down the decrease in CDR-SB (WMD: −0.45; 95% CI: −0.64, −0.25; p < 0.00001), ADCOMS (WMD: −0.05; 95% CI: −0.07, −0.03; p < 0.00001), ADAS-cog (WMD: −1.11; 95% CI: −1.64, −0.57; p < 0.0001), amyloid PET SUVr (WMD: −0.15; 95% CI: −0.48, 0.19; p = 0.38), amyloid burden on PET (WMD:−35.44; 95% CI: −65.22,−5.67; p = 0.02), adverse events (subjects with any TEAE) (OR: 0.73; 95% CI: 0.25, 2.15; p = 0.57), ARIA-E (OR:8.95; 95% CI: 5.36, 14.95; p < 0.00001), and ARIA-H (OR:2.00; 95% CI: 1.53, 2.62; p < 0.00001) in early AD patients.ConclusionOur analysis found that lecanemab showed significant positive statistical efficacy with respect to cognition, function, and behavior in patients with early AD though the actual clinical significance is yet to be establishedSystematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/#recordDetails, identifier: CRD42023393393.
