NEW YORK, June 6 (Reuters) – Drugmaker Eli Lilly presented trial results to medical professionals on Saturday showing its next-generation obesity drug ​retatrutide curbed sleep apnea severity in addition ‌to boosting weight loss and helping knee pain.

• In a Phase 3 trial, Lilly found a weekly injection of retatrutide reduced moderate-to-severe obstructive sleep apnea severity by 60.6% ‌in ​adults with obesity. Lilly’s older ⁠drug Zepbound is approved ⁠for the condition.

• In the same trial, the drug reduced knee osteoarthritis pain by up to 73.1%, Lilly found. The results were presented ​at an American Diabetes Association conference in New Orleans.

• Lilly previously disclosed results of the ⁠two studies presented on Saturday ⁠showing patients with obesity lost 28% ​of body weight and adults with type 2 ​diabetes experienced significant drops in blood sugar levels.

• ‌In one of the studies, 2% of patients with diabetes who took the lowest dose of the drug experienced major adverse cardiovascular events. Such ⁠events were not necessarily caused by the drug, according to detailed results published in the Lancet on Saturday.

• ⁠Retatrutide is ‌Lilly’s experimental “triple G” drug, which targets ⁠GLP-1, a second obesity-related hormone called ​GIP ‌and the body’s receptors for a ​third hormone ⁠called glucagon.

• The Indiana-based company and rivals including Denmark’s Novo Nordisk are in a race to dominate the booming market for obesity and diabetes drugs.
