Ervin, C., Joish, V. N., Evans, E., DiBenedetti, D., Reaney, M., Preblick, R., Castro, R., Danne, T., Buse, J. B., & Lapuerta, P. (2019). Insights into patients' experience with type 1 diabetes: Exit interviews from phase III studies of sotagliflozin. Clinical Therapeutics, 41(11), 2219-2230.e6. https://doi.org/10.1016/j.clinthera.2019.09.003
PURPOSE: The purpose of this study was to conduct qualitative participant interviews to provide context to the meaningfulness of improvements in end points seen in 2 large-scale Phase III sotagliflozin trials in participants with type 1 diabetes.
METHODS: Participants were eligible for an interview if they had exited one of the clinical trials within the previous 12 months. Participants were recruited by investigators at the clinical trial sites, and interviews were conducted by independent interviewers by telephone in accordance with a semistructured interview guide. Both interviewers and participants were blinded to treatment assignment. Qualitative analysis was conducted using ATLAS-ti version 7.5, and descriptive statistics were computed and summarized.
FINDINGS: Across 3 countries, 41 participants were interviewed. Difficulty maintaining blood glucose within a desired range, described by participants as lack of blood glucose "stability," was the most concerning symptom that they reported, wanting to see it improved during the clinical trial because it negatively impacted their physical, mental, and emotional lives. Participants who reported symptom improvement also reported a positive psychosocial impact while taking the clinical trial medication. All participants who monitored ketones described themselves as being "pretty confident" to "very confident" that they could avoid diabetic ketoacidosis by monitoring both ketone levels and understanding the physical signs and symptoms of hyperglycemia.
IMPLICATIONS: Improvements in glucose stability and control were important to participants with type 1 diabetes, as these improvements were correlated with improvements in the participants' lives. ClinicalTrials.gov identifiers: NCT02384941; NCT02421510.
