IMPORTANCEThe US Food and Drug Administration (FDA) Amendments Act of 2007 authorized the FDA to impose safety requirements on drugs with important risks, such as prescriber certification or routine laboratory testing, to ensure that the benefits of use outweighed the risks. However, little is known about patient and caregiver experiences with these Risk Evaluation and Mitigation Strategy (REMS) programs with Elements to Assure Safe Use (ETASU). OBJECTIVE To understand patient and caregiver experiences with and perceptions of REMS programs with ETASU. DESIGN, SETTING, AND PARTICIPANTS This qualitative study included semistructured qualitative phone interviews conducted between 2016 and 2017, with initial analysis performed in 2017 and reanalysis performed in 2021. Adult patients prescribed natalizumab or sodium oxybate, adult patients or caregivers of adult patients prescribed vigabatrin, and adult female patients of reproductive age prescribed riociguat were included.
MAIN OUTCOMES AND MEASURESAssessment of knowledge, decision-making, medication access, and perceptions of medical privacy. RESULTS Among 63 participants, 46 (73%) were female. Twenty-five participants (40%) had taken natalizumab, 10 (16%) riociguat, 15 (24%) sodium oxybate, and 10 (16%) vigabatrin. One participant had taken both natalizumab and vigabatrin; 4 (6%) were caregivers of patients using vigabatrin. Most participants expressed knowledge of REMS program requirements, but many lacked the insight that these requirements were part of an FDA-mandated special safety program and expressed difficulty understanding program education materials. REMS requirements made some participants more likely to initiate treatment. However, many reported burdens accessing medication, including the need to travel to certified prescribers or pharmacies. Manufacturer access to personal health information was also controversial, although some participants expressed an altruistic desire to assist others.
CONCLUSIONS AND RELEVANCEThis qualitative study found that REMS programs with ETASU reassured patients and their caregivers about drug safety and helped support medication initiation.However, steps are needed to improve the quality of REMS educational materials, promote efficient medication access, and protect patient privacy.
