Why do some post marketing commitment studies take so long to complete?

There are many steps involved in conducting studies. A protocol must be developed, and investigators (researchers) must be trained to conduct the study. Patient enrollment may take time for some studies, such as pediatric or sub-population studies. Some studies are designed to monitor the medicine over long periods of time to better understand the long-term effects. Furthermore, some safety studies may be required for the lifetime of the medicine. For more details, see Post Marketing Commitments Study Development Process.

How is this website different from the FDA's post marketing commitments website?

This website provides the current status of Pfizer post marketing commitments listed on the FDA website and includes US post marketing commitments established since August 1, 2000. Information on this website is believed to be correct at the time of posting. The status of post marketing commitments shown on the FDA website may differ from information displayed on this site, due to differences in the timing of updates made to the FDA website. The number of commitments on the two sites may also differ, due to the frequency of such updates and/or due to multiple reporting of single commitments on the FDA website.
