Insulin Glargine(Samsung Bioepis Co., Ltd.)

Eli Lilly’s once-weekly insulin candidate efsitora alfa has shown promise as a treatment for type 2 diabetes (T2D), according to new late-stage results announced by the company. It is hoped that the introduction of an insulin option specifically designed for once-weekly subcutaneous administration could improve adherence rates and quality of life for patients with the chronic condition. The phase 3 QWINT-1 trial randomised adults with T2D who were using basal insulin for the first time to receive either efsitora or once-daily insulin glargine. Efsitora was titrated across four fixed doses at four-week intervals, as needed for blood glucose control, Lilly said, noting that fixed dose regimens could make it easier for patients to start and manage insulin therapy. The primary endpoint of non-inferior A1C reduction at 52 weeks was met, with efsitora reducing A1C by 1.31% compared to 1.27% for insulin glargine, resulting in an A1C of 6.92% and 6.96%, respectively. Non-inferior A1C reductions were also seen in the phase 3 QWINT-3, which compared efsitora to once-daily insulin degludec in adults switching from daily basal injections. Efsitora reduced A1C by 0.86% compared to 0.75% for insulin degludec at week 26, resulting in an A1C of 6.93% and 7.03%, respectively. The overall safety and tolerability profile of efsitora was similar to that of daily T2D basal insulin therapies in both QWINT-1 and QWINT-3, Lilly said, adding that detailed results from the studies will be shared at an upcoming congress and published in a peer-reviewed journal. More than 4.3 million people in the UK have diabetes and T2D accounts for approximately 90% of all cases. There is currently no cure for T2D, with current treatment options focused on disease management, including diet and exercise, diabetes medications and insulin therapy. Jeff Emmick, senior vice president, product development at Lilly, said: “Many patients are reluctant to start insulin because of the burden it places on them. “With a simple fixed-dose regimen, once-weekly efsitora could make it easier for people with diabetes to start and manage insulin therapy, while reducing the impact it has on their day-to-day lives.”

In the phase 3 study, QWINT-1, efsitora was administered via four fixed doses once weekly in a single-use autoinjector in people with type 2 diabetes using basal insulin for the first time In a second phase 3 study, QWINT-3, efsitora also delivered non-inferior A1C reduction compared to daily insulin in people with type 2 diabetes switching from daily basal injections INDIANAPOLIS, Sept. 5, 2024 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced positive topline results from the QWINT-1 and QWINT-3 phase 3 clinical trials evaluating once weekly insulin efsitora alfa (efsitora) in adults with type 2 diabetes using basal insulin for the first time (insulin naïve) and in those who have switched from daily basal insulin injections, respectively. In these long-term treat-to-target trials, efsitora showed non-inferior A1C reduction compared to the most frequently used daily basal insulins globally. "Once weekly insulins, like efsitora, have the potential to transform diabetes care as we know it," said Jeff Emmick, M.D., Ph.D., senior vice president, product development, Lilly. "Many patients are reluctant to start insulin because of the burden it places on them. With a simple fixed-dose regimen, once-weekly efsitora could make it easier for people with diabetes to start and manage insulin therapy, while reducing the impact it has on their day-to-day lives." QWINT-1 evaluated the efficacy and safety of once weekly efsitora compared to once daily insulin glargine for 52 weeks. The trial randomized adults with type 2 diabetes who are insulin naïve to receive either efsitora once weekly in a single-use autoinjector or insulin glargine once daily. Efsitora was titrated across four fixed doses1 at four-week intervals, as needed for blood glucose control. The study's goal was to provide data supporting real-life applications of fixed dose regimens, which have the potential to make it easier for people living with diabetes to start and manage insulin therapy. The trial met its primary endpoint of non-inferior A1C reduction with efsitora compared to insulin glargine at week 52. For the efficacy estimand2,3, efsitora reduced A1C by 1.31% compared to 1.27% for insulin glargine, resulting in an A1C of 6.92% and 6.96%, respectively4. For the treatment-regimen estimand5,6, efsitora reduced A1C by 1.19% compared to 1.16% for insulin glargine, resulting in an A1C of 7.05% and 7.08%, respectively4. QWINT-3 evaluated the efficacy and safety of once weekly efsitora compared to once daily insulin degludec for 78 weeks in adults with type 2 diabetes currently treated with basal insulin. Participants were randomized 2:1 to receive either efsitora once weekly or insulin degludec once daily. The QWINT-3 trial met its primary endpoint of non-inferior A1C reduction with efsitora compared to insulin degludec at week 26. For the efficacy estimand7, efsitora reduced A1C by 0.86% compared to 0.75% for insulin degludec resulting in an A1C of 6.93% and 7.03%, respectively8. For the treatment-regimen estimand9, efsitora reduced A1C by 0.81% compared to 0.72% for insulin degludec resulting in an A1C of 6.99% and 7.08%, respectively10. Additionally, participants taking efsitora or insulin degludec spent approximately two hours more time in range (glucose 70-180 mg/dL) per day for weeks 22-26 compared to baseline. For the efficacy estimand11, participants taking efsitora spent 62.8% of time in range compared to 61.3% for insulin degludec for weeks 22-2612. For the treatment-regimen estimand13, participants taking efsitora spent 61.4% of time in range compared to 61% for insulin degludec14. Further, for the efficacy estimand, participants taking efsitora spent 38.3% of time in tight range (glucose 70-140 mg/dL) compared to 36.8% for insulin degludec for weeks 22-2615. In both QWINT-1 and QWINT-3, the overall safety and tolerability profile of efsitora was similar to that of daily basal insulin therapies for the treatment of type 2 diabetes. In QWINT-1, estimated combined rates of severe or clinically significant (blood glucose <54 mg/dL) hypoglycemic events per patient-year of exposure from weeks 0-52 were 0.50 with efsitora vs. 0.88 with insulin glargine – approximately 40% lower with efsitora than insulin glargine. In QWINT-3, estimated combined rates of severe or clinically significant (blood glucose <54 mg/dL) hypoglycemic events per patient-year of exposure from weeks 0-78 were 0.84 with efsitora vs. 0.74 with insulin degludec. Detailed results for QWINT-1 and QWINT-3 will be shared at an upcoming congress and published in a peer-reviewed journal. Additionally, detailed results for QWINT-2 and QWINT-5 will be presented at the European Association for the Study of Diabetes (EASD) Annual Meeting 2024. About the QWINT clinical trial program The QWINT phase 3 global clinical development program for insulin efsitora alfa (efsitora) in diabetes began in 2022 and has enrolled more than 4,000 people living with type 1 or type 2 diabetes across five global registration studies. QWINT-1 (NCT05662332) was a parallel-design, open-label, treat-to-target, randomized controlled clinical trial comparing the efficacy and safety of efsitora as a once weekly basal insulin using a fixed dose to insulin glargine for 52 weeks in insulin-naïve adults with type 2 diabetes. The trial randomized 796 participants across the U.S., Argentina, Mexico and Puerto Rico to receive efsitora once weekly or insulin glargine once daily administered subcutaneously. All participants treated with efsitora received a starting dose of 100 units followed by a fixed dose escalation to achieve a target fasting blood glucose of 80-130 mg/dL. Fasting blood glucose was measured every four weeks and participants escalated to fixed dosages of 150 units, 250 units and 400 units as appropriate. Participants with fasting blood glucose greater than 130 mg/dL on or after 16 weeks were transferred to flexible dosing. The primary objective of the trial was to demonstrate non-inferiority in reducing A1C at week 52 with efsitora compared to insulin glargine. QWINT-3 (NCT05275400) was a multicenter, randomized, parallel-design, open-label trial comparing the efficacy and safety of efsitora as a once-weekly basal insulin to insulin degludec for 78 weeks after a three-week lead-in period, and followed by a five-week safety follow up period, in adults with type 2 diabetes who are currently treated with basal insulin. The trial randomized 986 participants across the U.S., Argentina, Hungary, Japan, Korea, Poland, Puerto Rico, Slovakia, Spain and Taiwan to receive efsitora once weekly or insulin degludec once daily administered subcutaneously. The primary objective of the study was to demonstrate non-inferiority in reducing A1C at week 26 with efsitora compared to insulin degludec. About insulin efsitora alfa Insulin efsitora alfa (efsitora) is a once-weekly basal insulin, a fusion protein that combines a novel single-chain variant of insulin with a human IgG2 Fc domain. It is specifically designed for once-weekly subcutaneous administration, and with its low peak-to-trough ratio, it has the potential to provide more stable glucose levels (less glucose variability) throughout the week. Efsitora is in phase 3 development for adults with type 1 and 2 diabetes. About Lilly Lilly is a medicine company turning science into healing to make life better for people around the world.
