Lotus is known world wide as a top-enrolling center for all types of analgesic research studies.
We have the world's largest analgesic clinical trial database with over 12,000 potential study volunteers. Our database has been accrued over the past 12 years utilizing nearly $5 million dollars in cumulative advertising funds. It is lovingly maintained, sorted and pruned to yield excellent enrollment results.

*Each clinical trial has its own enrollment challenges therefore, the only way to judge a site’s enrollment is to compare it to other research sites that performed the same study concurrently. Therefore, Lotus tabulates its enrollment performance at the end of each study in the following way: (1) the number of patients enrolled by Lotus is divided by the number of months of active enrollment to generate a patient-per-month figure. (2) the number of patients enrolled by all other centers over the open enrollment period is calculated (x). That number (x) is then divided by the number of months of open enrollment and then again by the number of non-Lotus sites to generate an average non-Lotus site patient-per-month figure. In this way an “apples to apples” comparison can be made; and isn’t that what we are all striving for?
