Novo Nordisk A/S: Oral semaglutide 50 mg achieved 15.1% weight loss (17.4% if all people adhered to treatment) in adults with obesity or overweight in the OASIS 1 trial
Bagsværd, Denmark, 22 May 2023 – Novo Nordisk today announced headline results from OASIS 1, a phase 3a trial in the global OASIS programme. OASIS 1 is a 68-week, efficacy and safety trial comparing once-daily oral semaglutide 50 mg for weight management to placebo in 667 adults with obesity or overweight with one or more comorbidities. Both treatment arms were in conjunction with lifestyle intervention. The trial achieved its primary endpoint by demonstrating a statistically significant and superior weight loss at week 68 with oral semaglutide 50 mg versus placebo.
When evaluating the effects of treatment if all people adhered to treatment1 from a mean baseline body weight of 105.4 kg, people treated with oral semaglutide 50 mg achieved a statistically significant weight loss of 17.4% after 68 weeks compared to a 1.8% reduction with placebo. In addition, 89.2% of those who received oral semaglutide 50 mg, reached a weight loss of 5% or more after 68 weeks, compared to 24.5% with placebo.
When applying the treatment policy estimand2, people treated with oral semaglutide 50 mg achieved a superior weight loss of 15.1% compared to a reduction of 2.4% with placebo and 84.9% achieved a weight loss of 5% or more, compared to 25.8% with placebo.
“We are very pleased with the weight loss demonstrated by the once-daily oral formulation of semaglutide in obesity. The results show comparable weight loss as in the STEP 1 trial with injectable semaglutide 2.4 mg in obesity branded as Wegovy®”, said Martin Holst Lange, executive vice president for Development at Novo Nordisk. ”The choice between a daily tablet or weekly injection for obesity has the potential to offer patients and healthcare providers the opportunity to choose what best suits individual treatment preferences”.
In the trial, oral semaglutide 50 mg appeared to have a safe and well-tolerated profile. The most common adverse events were gastrointestinal, and the vast majority were mild to moderate and diminished over time and were consistent with the GLP-1 receptor agonist class. Gastrointestinal adverse events were most prominent during dose escalation.
Novo Nordisk expects to file for regulatory approval in the US and the EU in 2023. The global launch of oral semaglutide 50 mg is contingent on portfolio prioritisations and manufacturing capacity.
