Once-Weekly Basal Insulins

Lilly's Onswik Reduces Basal Injections to Once Weekly

Eli Lilly is expanding type 2 diabetes treatment options with Onswik, a once-weekly basal insulin recently approved by the FDA. Designed to provide steady basal insulin levels for seven days, Onswik reduces injection frequency compared to traditional daily basal insulin. Its approval is supported by the QWINT Phase 3 program, which studied more than 3,400 adults and found comparable A1C reductions to daily insulin glargine or insulin degludec across the trials.

The weekly format addresses the treatment burden associated with frequent injections, potentially offering greater flexibility for adults managing type 2 diabetes. For Lilly, Onswik expands its established insulin portfolio with a differentiated dosing schedule as diabetes treatment becomes increasingly focused on convenience and adherence. The upcoming U.S. availability of two KwikPen concentrations also gives healthcare providers additional prescribing options while positioning Lilly to compete within the emerging market for reduced-frequency insulin therapies.
