> The [letter](http://www.legalreader.com/essure-investigation-and-congressional-hearing-request/?ref=fdaweb.com) says the investigation is needed because Essure’s clinical trials were inadequate and inappropriate from the beginning. **“**The clinical trials were insufficient as they followed too few women for too short a period of time,” the letter says. “The premarket approval was based on two non-randomized, non-blinded, prospective studies that lacked a comparator group and enrolled a total of 926 women.” The letter also complained that FDA did not weigh accordingly complaints about serious side effects and injuries tied to Essure.
