Eli Lilly’s retatrutide triple agonist demonstrated strong weight loss efficacy in type 2 diabetes patients in the TRIUMPH-2 Phase 3 trial, challenging the previous assumption that diabetes blunts the weight loss effect of GLP-1 therapies. This suggests a need to rethink metabolic trial designs, especially the sequencing of diabetes and obesity populations in drug development.

◆ ◆ The Wire takeaway
Your diabetes drug development no longer needs to treat type 2 diabetes as a strictly tougher market to crack. You can prioritise type 2 diabetes patients earlier with triple agonists like retatrutide, which flip the old weight-loss efficacy assumptions and open direct market access.
