Which lead sponsors run the most Asperger Syndrome trials? (3)
Shown in this order: most trials first. Lead sponsors the registry classes as industry, NIH, US federal, other government or network. A hospital or university the registry files as government can appear here. Sponsors it classes as academic or other are shown on the full page, because that class cannot separate an institution from a named investigator.

| Forest Laboratories | 3 |
| National Institute of Mental Health (NIMH) | 3 |
| Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) | 2 |

These are the names sponsors entered on ClinicalTrials.gov that we have not matched to a single molecule. Some are drugs under a brand or code name; others are procedures, doses or arm labels.
Which serious adverse events do Asperger Syndrome trials report? (10)
