With once-a-week dosing, insulin efsitora alfa delivers similar A1C reduction compared to daily insulin in adults with type 1 diabetes
Eli Lilly and Company (NYSE: LLY) announced detailed results from the QWINT-5 phase 3 trial evaluating once-weekly insulin efsitora alfa compared to once-daily insulin degludec in adults with type 1 diabetes. The study met its primary endpoint of non-inferior A1C reduction at week 26, with efsitora reducing A1C by 0.53% compared to 0.59% for insulin degludec. Key secondary endpoints showed similar time in range and rates of nocturnal hypoglycemic events between the two treatments.
However, efsitora showed higher rates of severe hypoglycemic events (0.14 vs 0.04 per patient-year) compared to insulin degludec, with 64% of these events occurring in the first 12 weeks of treatment. The results highlight the potential of efsitora to offer a once-weekly basal insulin option for type 1 diabetes patients, while also emphasizing the need for careful management of hypoglycemia risk.

The QWINT-5 phase 3 trial results for Eli Lilly's once-weekly insulin efsitora alfa are promising for type 1 diabetes management. The primary endpoint of non-inferior A1C reduction compared to daily insulin degludec was met, with efsitora reducing A1C by
Key secondary endpoints showed comparable results between efsitora and degludec in time in range and rates of nocturnal hypoglycemic events. However, the higher rate of severe hypoglycemic events with efsitora (
While these results are encouraging, further research is needed to optimize dosing and minimize hypoglycemia risk before efsitora can be considered a game-changer in type 1 diabetes treatment.
The QWINT-5 trial results for efsitora alfa are intriguing from a clinical perspective. The similar A1C reduction and time in range compared to daily insulin degludec suggest potential for improved patient convenience without compromising glycemic control. This could significantly enhance treatment adherence, a common challenge in diabetes management.
However, the increased rate of severe hypoglycemic events is concerning, particularly in the first 12 weeks of treatment. This highlights the need for careful titration and close monitoring during initiation. The similar rates of nocturnal hypoglycemia are reassuring, but the overall hypoglycemia risk needs further evaluation.
While efsitora shows promise, its adoption in clinical practice will depend on balancing improved convenience with potential safety concerns. Personalized treatment approaches and patient education will be important for its successful implementation.
Eli Lilly's efsitora alfa trial results present a mixed picture for investors. The non-inferiority to daily insulin in A1C reduction is a significant milestone, potentially opening a large market for weekly insulin in type 1 diabetes. This could drive substantial revenue growth for Lilly, given the lifelong nature of type 1 diabetes treatment.
However, the higher rate of severe hypoglycemic events is a red flag that could impact regulatory approval or limit market adoption. The fact that
Investors should closely watch for regulatory feedback and potential label restrictions. While efsitora could be a game-changer, its success will hinge on balancing efficacy, safety and patient convenience. The market reaction may be cautiously optimistic, but significant uncertainties remain.

In the trial, efsitora met the primary endpoint of non-inferior A1C reduction at week 26. For the efficacy estimand1,2, efsitora reduced A1C by
In a key secondary endpoint, time in range4 as measured by continuous glucose monitoring (CGM) was similar between efsitora and insulin degludec during the four weeks prior to week 26. In an additional key secondary endpoint, the estimated combined rates of patient-reported clinically significant (blood glucose <54 mg/dL) or severe nocturnal5 hypoglycemic events per patient-year of exposure were similar between efsitora and insulin degludec over the 52-week study period.
"People with type 1 diabetes need insulin every day. Currently, they can deliver the insulin using an automated insulin delivery system or by taking a daily basal insulin injection and multiple mealtime insulin injections each day," said Richard Bergenstal, M.D., executive director of the International Diabetes Center, HealthPartners Institute. "This new data shows that with one dose a week of basal insulin, efsitora was able to achieve a similar A1C reduction as taking an injection of one of the most used background insulins every day. I look forward to further evaluation of these data, including ways to minimize hypoglycemia, so once-weekly insulin can be one option for personalizing the management of type 1 diabetes."

Overall incidence of treatment-emergent adverse events were comparable across treatment groups. Serious adverse events were higher in efsitora compared to insulin degludec, driven by severe hypoglycemic events.
"When we commercialized insulin more than 100 years ago, it marked the beginning of our commitment to people living with type 1 diabetes – today's announcement continues that legacy," said Jeff Emmick, M.D., Ph.D., senior vice president, product development, Lilly. "These results underscore the potential of efsitora to help some people living with type 1 diabetes lower their A1C with only one basal insulin injection per week, while also highlighting the complexity of treating this chronic disease. With the data we have seen from our phase 3 program so far, we are confident in efsitora's potential to transform diabetes care and will continue to pursue new treatment options until we can eliminate the disease entirely."
Detailed results for QWINT-2 are also being presented at EASD and simultaneously published in The New England Journal of Medicine.

The trial consisted of a 52-week treatment period with the primary endpoint measured at 26 weeks. 692 participants across the
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, 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.
