Tokyo, Nov 30 (EFE).- A new drug that slows down the effects of Alzheimer's in the early stages of the disease has brought hope to patients and families after a clinical study proving its efficacy was published on Wednesday.

The study, which was issued by The New England Journal of Medicine, also warned that the use of the drug had presented adverse effects and required more in-depth analysis.

The new drug, lecanemab, is capable of reducing the "clinical decline on the global cognitive and functional scale, CDR-SB, compared with placebo at 18 months by 27%," Eisai global, a Japanese pharmaceutical company that developed the drug with US-based Biogen, reported.

The phase three study was carried out at various medical centers over 18 months, with 1,795 patients who were in the early stages of the disease and aged 50 to 90.

"Today's announcement gives patients and their families hope that lecanemab, if approved, can potentially slow the progression of Alzheimer's disease, and provide a clinically meaningful impact on cognition and function," said Michel Vounatsos, CEO at Biogen.

Results from the clinical trial show that the monoclonal antibody present in lecanemab reduced markers of amyloid in early Alzheimer's disease and resulted in less cognitive decline than the placebo after 18 months.

The study also concluded that the drug was associated with adverse effects and that "longer trials are warranted to determine the efficacy and safety of lecanemab in early Alzheimer's disease."

Eisai and Biogen plan to file for full approval of the drug in the US in January, and soon after in Japan and Europe. EFE
