U.S. Food and Drug Administration’s Patient-Focused Drug Development Initiative: Experience with Integration of Patient-Experience Data in a New Drug Application for Esketamine Nasal Spray Plus a Newly Initiated Oral Antidepressant for Treatment-Resistant Depression

The Patient-Focused Drug Development initiative of the U.S. Food and Drug Administration (FDA) aims to ensure that the patient experience of disease and treatment is an integral component of the drug development process. The 21st Century Cures Act and Prescription Drug User Fee Act (PDUFA) VI require the FDA to publicly report the type of patient-experience data reviewed in a new drug application (NDA) to inform regulatory decision-making. This report describes a recent approach adopted at Janssen of integrating patient-experience data into the NDA for esketamine (SPRAVATO®) nasal spray with a newly initiated oral antidepressant (esketamine + AD) for treatment-resistant depression. During the development of esketamine + AD, patient-experience data were collected using several patient-reported outcomes, including the Sheehan Disability Scale and 9-item Patient Health Questionnaire (PHQ-9). Additionally, a patient-preference study assessed the relative importance of benefits and harms that patients allocated to different attributes of treatment. Preferences were collected from patients enrolled in phase 3 esketamine trials and from an online panel of primarily ketamine-naive patients. Patient-experience data were integrated into the esketamine NDA, the FDA advisory committee meeting briefing document, and the Sponsor’s presentation. The FDA acknowledged reviewing the patient-experience data and determined that they supported esketamine + AD for treatment-resistant depression. This report highlights the importance of integrating patient-experience methods early in drug development, their impact on assessing patient-relevant benefits and risks, and how they can help improve clinical program design.
