But it may be too soon to establish a clear winner in the pill space, as there is no data comparing Eli Lillly’s drug with a higher dose of Novo Nordisk’s pill in patients with obesity.Eli Lilly said its pill, orforglipron, was superior at the trial’s main goal of lowering blood sugar levels at 52 weeks compared to Novo Nordisk’s oral semaglutide. The highest dose of orforglipron helped lower hemoglobin A1c — a measure of blood sugar levels — by 2.2% compared to 1.4% with Novo Nordisk’s pill. The highest dose of Eli Lilly’s drug also helped patients lose an average of 9.2% of their weight, or 19.7 pounds, compared to 5.3% weight loss, or 11 pounds, with Novo Nordisk’s pill. Orforglipron’s weight loss was 8.2% when analyzing all patients regardless of discontinuations, while oral semaglutide’s was 5.3%. The results suggest an up to 36-milligram dose of Eli Lilly’s pill may be more effective at treating diabetes patients than an up to 14-milligram dose of oral semaglutide, which is already approved under the name Rybelsus for Type 2 diabetes.”For the majority of patients, this could be the main medicine that they need to control their Type 2 diabetes as well as their obesity,” Eli Lilly Chief Scientific Officer Dan Skovronsky said in an interview.Dr. Michael Weintraub, an endocrinologist at NYU Langone Diabetes & Endocrine Associates, said orforglipron’s management of blood sugar levels is “quite impressive not only compared to other oral type 2 diabetes medications but all type 2 diabetes medications including injectables.”The company on Wednesday said it expects to apply for approval of orforglipron for the treatment of Type 2 diabetes in 2026. Eli Lilly hopes to launch its pill globally “this time next year,” CEO David Ricks told CNBC in early August.Eli Lilly and Novo Nordisk are vying for a greater share of the booming market for GLP-1s, which some analysts say could be worth around $100 billion by the 2030s. The space is eager for more convenient options that could ease the supply shortfalls and access hurdles created by the pricey weekly injections currently dominating it.Oral GLP-1s could grow to be worth $50 billion of that total, according to some analyst estimates.Limits to the studyBut it’s less clear how Eli Lilly’s pill compares to higher doses of oral semaglutide, especially in patients who are overweight or have obesity without diabetes. Novo Nordisk expects U.S. regu …
