Perceptions of the Benefits and Risks of Novel Therapies for Type 1 Diabetes: A Qualitative Study

Abstract

Introduction: Novel therapies, including disease-modifying and cell replacement therapies, may preserve or replace beta cells in people with type 1 diabetes. This study sought to understand how people living with type 1 diabetes or caring for someone with type 1 diabetes perceive the benefits and risks of novel therapies. Methods: Semistructured qualitative interviews were conducted with 26 participants in the United States: four adolescents and 12 adults with type 1 diabetes, and 10 caregivers of children with type 1 diabetes. A description of the benefits and risks of disease-modifying and cell replacement therapies, developed with a steering committee of patients and clinicians, was presented during interviews to facilitate discussion among people living with type 1 diabetes and caregivers. A qualitative directed content analysis was conducted. Results: Participants reported that type 1 diabetes and insulin therapy regimens impacted many life areas, with some participants reporting diabetes burnout. Most participants expressed that they would have considered trying disease-modifying therapies, most frequently citing perceived benefits such as reduced insulin reliance and an extended post-diagnosis “honeymoon period” providing time to prepare for life with diabetes. Cancer risk was the most frequently reported risk of concern for disease-modifying therapies. All participants expressed willingness to consider cell replacement therapies, with insulin independence and restored pancreatic function perceived to offer greater normalcy and freedom from the constant demands of diabetes. Participants reported concerns about the use of immunosuppressants and the risks and drawbacks of the cell replacement surgical procedure. Conclusions: Despite concerns about the risks and drawbacks of novel therapies, most participants reported that they would consider trying disease-modifying and cell replacement therapies. There is no substitute for consulting people living with or caring for someone with type 1 diabetes when considering new therapies with novel risks and benefits.
