A daily pill may be as effective in lowering blood sugar and aiding weight loss in people with Type 2 diabetes as the popular injectable drugs Mounjaro and Ozempic, according to results of a clinical trial announced by Eli Lilly on Thursday morning.

The drug, orforglipron, is a GLP-1, a class of drugs that have become blockbusters because of their weight-loss effects. But GLP-1s are expensive, must be kept refrigerated and must be injected. A pill that produces similar results has the potential to become far more widely used.

“In the coming decades, 700 million people around the world will have Type 2 diabetes, and over a billion will have obesity,” said Dr. Daniel Skovronsky, Lilly’s chief scientific officer. “Injections cannot be the solution for billions of people around the world.”

The results Lilly announced came from a clinical trial involving 559 people with Type 2 diabetes who took the new pill or a placebo for 40 weeks. In patients who took orforglipron, blood sugar levels fell by 1.3 to 1.6 percent, about the same amount in that time period experienced by patients taking Ozempic and Mounjaro in unrelated trials. For 65 percent of people taking the new pill, blood sugar levels dropped into the normal range.

Patients on the new pill also lost weight — up to 16 pounds without reaching a plateau at the study’s end. Their weight loss was similar to that achieved in 40 weeks with Ozempic but slightly less than with Mounjaro in unrelated trials.

Side effects were the same as those with the injectable obesity drugs — diarrhea, indigestion, constipation, nausea and vomiting.
