The US Food and Drug Administration (FDA) Amendments Act of 2007 authorized the FDA to require risk evaluation and mitigation strategy (REMS) programs for drugs with important safety concerns. REMS can have elements to assure safe use (ETASU), such as patient registries, dispensing restrictions, and physician training and certification requirements. We aimed to understand physician experiences with and perceptions of a selection of ETASU REMS.

Physicians prescribing 1 of 4 ETASU REMS-covered drugs: natalizumab, riociguat, sodium oxybate, and vigabatrin.

Descriptive phenomenological study based on semi-structured phone interviews.

Qualitative content analysis to summarize physician responses to open-ended questions.

Of 31 physicians (14 female), 6 prescribed riociguat, 6 vigabatrin, 7 sodium oxybate, and 12 natalizumab (5 for Crohn's disease, 7 for multiple sclerosis), most demonstrated good understanding of the rationale for and requirements of the ETASU REMS but believed that the programs had limited effect on clinical practice. Some physicians reported that the ETASU REMS made them more comfortable with prescribing covered drugs due to heightened oversight, facilitated discussions about treatment, and were likely more beneficial for non-specialists. Concerns were raised about the administrative effort needed to comply with the programs and the potential misuse of patient health information transmitted to manufacturers.

Physicians are generally aware of ETASU REMS and get reassurance from the additional oversight, but the programs can be better integrated into clinical workflows and can be designed to better protect patient health information.
