Lilly Reports Positive Data in Weekly Insulin Trials

Eli Lilly says data from its QWINT-1 and QWINT-3 Phase 3 clinical trials evaluating once-weekly insulin efsitora alfa in adults with Type 2 diabetes showed non-inferiority A1C reduction compared to the most frequently used daily basal insulins. The trials evaluated the therapy in patients using basal insulin for the first time and in those who have switched from daily basal insulin injections.

“Once weekly insulins, like efsitora, have the potential to transform diabetes care as we know it,” the company says. “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.”

The trial data showed that the primary endpoint of non-inferior A1C reduction with efsitora compared to insulin glargine at week 52 was met, according to Lilly. “For the efficacy estimand, efsitora reduced A1C by 1.31% compared to 1.27% for insulin glargine, resulting in an A1C of 6.92% and 6.96%, respectively,” it says.

Regarding safety, Lilly says that in both QWINT-1 and QWINT-3, efsitora’s overall safety and tolerability profile was comparable to that of daily basal insulin therapies. It plans to share more detailed data at an upcoming medical meeting and in a peer-reviewed journal.
