New Soliqua 100/33 data shows improved blood sugar control without weight gain versus premixed insulin
* Study also shows more people on Soliqua 100/33 had improved blood sugar control without weight gain and without low blood sugar events (hypoglycemia) in first head-to-head comparison with premixed insulin

PARIS, June 28, 2021 /PRNewswire/ -- A new study of Soliqua® 100/33 (insulin glargine and lixisenatide injection) 100 Units/mL and 33 mcg/mL, iGlarLixi, met its two primary endpoints and all key secondary endpoints in a head-to-head comparison against premixed insulin (biphasic insulin aspart 30, BIAsp 30) in adults living with type 2 diabetes, the most common form of diabetes, uncontrolled on insulin and one or two oral anti-diabetic medicines. The findings were presented today at the American Diabetes Association (ADA) 81st Scientific Sessions1 and simultaneously published in Diabetes Care.2

The study met both primary endpoints with Soliqua 100/33 demonstrating noninferiority of blood sugar (HbA1c) reduction and superiority on body weight change from baseline compared to premixed insulin. The study also met its key secondary endpoints with Soliqua 100/33 achieving a greater proportion of people reaching a HbA1c target of <7% without weight gain, a greater proportion of people reaching a HbA1c target of <7% without weight gain and without hypoglycemia, and superiority in reduction of HbA1c compared with those using premixed insulin.

"Concerns about hypoglycemia and weight gain are known barriers when advancing basal insulin therapy, especially with complex insulin regimens," says Julio Rosenstock, Director of the Dallas Diabetes Research Center at Medical City, Dallas, TX, and main author of the study. "These results show improved outcomes with iGlarLixi over BIAsp 30, demonstrating better glucose control without body weight gain and less hypoglycemia. This combined benefit could help clinicians consider advancing basal insulin therapy by switching to a once-daily fixed-ratio combination of basal insulin plus a GLP-1 receptor agonist rather than switching to a twice-daily premixed insulin regimen."

A secondary analysis also found study participants using Soliqua 100/33 reported greater improvements in patient-reported outcomes compared to premixed insulin as measured by Treatment-Related Impact Measure Diabetes (TRIM-D) and patient- and physician-rated Global Treatment Effectiveness Evaluation (GTEE) scores.3 These tools include measurements of treatment burden, daily life, diabetes management, compliance, psychological health, and treatment effectiveness.

"Despite the advances in diabetes care, many people living with type 2 diabetes are unable to reach their HbA1c goals," said Luigi Meneghini, M.D., US Medical Head of Diabetes, General Medicines at Sanofi. "This study highlights appropriate options for earlier treatment intensification for those not reaching their blood sugar goals, and these data suggest that Soliqua 100/33 may be a superior therapy for these people compared to premixed insulins."

Safety findings were in line with the established profiles of Soliqua 100/33 and premixed insulin.

About the SoliMix study

The SoliMix study was a 26-week, randomized controlled trial of 887 adults living with type 2 diabetes who were uncontrolled on insulin plus metformin with or without a sodium-glucose cotransporter-2 inhibitor (SGLT-2i). The study compared the efficacy and safety of Soliqua 100/33 compared to a commonly used premixed insulin (BIAsp 30). Participants were randomized to switch from their prior insulin to either Soliqua 100/33 once daily or premixed insulin twice daily, with starting doses determined and adjusted weekly. Any metformin or SGLT-2i treatment was maintained through the study period. 

The study met its two primary endpoints and all three of its key secondary endpoints.

In a secondary analysis, participants using Soliqua 100/33 also reported greater improvements in patient-reported outcomes as measured by TRIM-D and patient- and physician-rated GTEE scores at 26 weeks.

  • TRIM-D results demonstrated greater improvements for participants using Soliqua 100/33 compared to those using premixed insulin, across domains including compliance, diabetes management, and psychological health, among others.3
  • GTEE findings showed that nearly twice as many patients reported complete control of their diabetes with Soliqua 100/33 compared to premixed insulin (27.5% vs 15%). Similarly, nearly twice as many physicians also reported treatment effectiveness (i.e., complete control of diabetes) with Soliqua 100/33 compared to premixed insulin (29.9% vs 15.3%).3

Safety findings were in line with the established profiles of both treatments. The most commonly reported adverse events in the study were hypoglycemia (31.2% Soliqua 100/33, 42.4% premixed insulin), nausea (7.7% Soliqua 100/33, 0% premixed insulin), headache (2.5% Soliqua 100/33, 0.5% premixed insulin), dizziness (1.4% Soliqua 100/33, 0.5% premixed insulin), and vomiting (1.1% Soliqua 100/33, 0.2% premixed insulin).
