The study found that once-weekly subcutaneous injections of CT-388 (titrated up to 24 mg) resulted in significant and clinically meaningful placebo-adjusted weight loss of 22.5% (efficacy estimand) without reaching a weight loss plateau at 48 weeks. A clear dose-response relationship on the weight loss was observed. For the treatment-regimen estimand, the placebo-adjusted weight loss achieved with CT-388 was 18.3% (p-value &lt; 0.001). At week 48 for the 24 mg dose, 95.7% of CT-388 treated participants achieved a weight loss of ≥5%, 87% achieved ≥10%, 47.8% achieved ≥20%, and 26.1% achieved ≥30%. 73% of participants who were pre-diabetic at baseline and treated with CT-388 at 24 mg achieved normal blood glucose levels at week 48 compared to 7.5% in the placebo group.","length":1028,"tagName":"p"},{"t...
