ClinicalTrials.gov provides a remarkable resource of information regarding drug development for AD and other disorders. Trends in AD drug development over time can be seen, and the movement of the drugs through the pipeline can be monitored. ClinicalTrials.gov has provided comprehensive information since 2007, when registration of clinical trials was required by the FDA. The analyses demonstrate that the number of clinical trials has been declining since the 2008 through 2009 period. The pharmaceutical industry sponsors most drug development for AD, whereas NIH accounts for a relatively small percentage of drug development. The United States has the largest number of clinical trials of any single country, but more clinical trials are conducted outside of the United States than inside of the United States.

Most trials address symptomatic agents intended to improve cognition, but disease-modifying small molecules and disease-modifying immunotherapies are also represented in the drug-development pipeline. More therapies address amyloid-beta targets than any other single target. Phase 2 trials are smaller and shorter than Phase 3 trials, and sponsors have relatively limited experience with most molecules when they enter Phase 3.

Most drugs entering the AD drug-development pipeline have failed; only one agent has been approved since 2004 (memantine). The failure rate since 2002 (excluding agents currently in Phase 3) is 99.6%. Currently, 108 trials of AD therapies represent 94 unique agents. This is a relatively small number of test compounds. The small number of agents in Phase 1 is particularly concerning, as it suggests that relatively few drugs are entering the AD drug-development process. Repurposed agents may enter the pipeline at later phases, but it is unlikely that a large number of repurposed agents will be assessed. The AD drug-development pipeline is relatively small, and the rate of success of AD clinical trials is limited. An urgent need exists to increase the number of agents entering the pipeline and progressing successfully toward new therapy for patients with AD.
