AZD-3293 camsylate wider known as Lanabecestat camsylate, a salt of Lanabecestat, a drug that was invented for the treatment of Alzheimer's disease. Lanabecestat inhibits beta-secretase 1 cleaving enzyme (BACE1) thus preventing the buildup of beta-amyloid and help stop the progression of Alzheimer's disease. The drug was in phase III clinical trials, but studies were discontinued because of recommendations by an independent data monitoring committee (IDMC). IDMC concluded that all trials, in early Alzheimer’s disease, and in mild Alzheimer’s disease dementia, were not likely to meet their primary endpoints upon completion and therefore should be stopped for futility.
