Patient-perceived benefits and risks of off-label use of SGLT2 inhibitors and GLP-1 receptor agonists in type 1 diabetes: a structured qualitative assessment

BACKGROUND: Patients with type 1 diabetes mellitus (T1DM) may have suboptimal glucose control and are interested in the use of adjuvant therapies. OBJECTIVES: To determine, from the patients’ perspective, the reasons for initiation of glucagon-like peptide 1 receptor agonist (GLP-1RA) and/or sodium...

Sumario:BACKGROUND: Patients with type 1 diabetes mellitus (T1DM) may have suboptimal glucose control and are interested in the use of adjuvant therapies. OBJECTIVES: To determine, from the patients’ perspective, the reasons for initiation of glucagon-like peptide 1 receptor agonist (GLP-1RA) and/or sodium glucose cotransporter 2 inhibitor (SGLT2i) in treating T1DM; perceived benefits/side effects, reasons for discontinuation, and willingness to reinitiate therapy. DESIGN: Retrospective chart review with structured telephone interviews. METHODS: We identified patients with T1DM treated with a GLP-1RA and/or SGLT2i for >3 months at University of Texas Southwestern Medical Center (Dallas, TX, USA) and Poznan University (Poznan, Poland). We conducted structured telephone interviews regarding their experiences. RESULTS: We interviewed 68 participants treated with GLP-1RA and 82 with SGLT2i. Treatment was initiated for improving glycemic control (as reported by 61.8% versus 81.7% of GLP-1RA and SGLT2i users, respectively), weight loss/appetite suppression (51.4% versus 23.2%) and to reduce insulin requirement (13.2% versus 11%). Most participants (86.8% of GLP-1RA and 89.0% of SGLT2i users) reported ⩾1 benefit attributed to therapy. Reported benefits were improved glycemic control (reported by 58.8% versus 82.9% of GLP-1RA and SGLT2i users, respectively), weight loss/appetite suppression (63.2% versus 30.5%), and reduced insulin requirement (27.9% versus 34.1%). More GLP-1RA users reported side effects versus SGLT2i users (63.2% versus 36.6%); 22.6% discontinued GLP-1RA due to side effects versus 11.0% SGLT2i users. Diabetic ketoacidosis (DKA) was reported by 4.9% of SGLT2i users, but none in GLP-1RA users. Of those who discontinued medication, 60.7% of GLP-1RA versus 56.0% of SGLT2i prior users were willing to reinitiate treatment. CONCLUSIONS: Patients with T1DM report initiating adjuvant treatment with GLP-1RA and/or SGLT2i to improve glycemic control and lose weight; most patients reported perceived benefits from these therapies. Side effects (including DKA) are reported more commonly in real life than in clinical trials. Given patient interest in these medications, further studies should evaluate the long-term risk–benefits ratio in larger cohorts.
