Novo Nordisk says PIONEER 5 trial of Oral semaglutide achieved primary objective
Novo Nordisk announced the headline results from PIONEER 5, a phase 3a trial with oral semaglutide in adults with type 2 diabetes and moderate renal impairment. Oral semaglutide is an investigational GLP-1 analogue taken once daily as a tablet. The 26-week trial investigated the efficacy and safety of 14 mg oral semaglutide compared with placebo in 324 people with type 2 diabetes and moderate renal impairment inadequately controlled with metformin, sulfonylurea alone or in combination with metformin, or basal insulin alone or in combination with metformin. Two distinct statistical approaches to evaluating the effects of oral semaglutide were applied in the PIONEER 5 trial; a primary statistical approach required by recent regulatory guidance evaluating the effect regardless of discontinuation of treatment and use of rescue medication, and a secondary statistical approach describing the effect while on treatment and without use of rescue medication. The trial achieved its primary objective according to the primary statistical approach by demonstrating statistically significant and superior reductions in HbA1c with oral semaglutide compared to placebo at week 26. Furthermore, people treated with oral semaglutide achieved statistically significant and superior reductions in body weight compared to placebo at week 26. When applying the secondary statistical approach, people treated with oral semaglutide experienced a statistically significantly greater reduction in HbA1c of 1.1% compared to 0.1% with placebo. Reduction in body weight was statistically significantly greater with oral semaglutide at week 26, with a reduction of 3.7 kg compared to 1.1 kg with placebo. In this 26-week trial, oral semaglutide was well-tolerated in people with moderate renal impairment, with a profile consistent with GLP-1-based therapies. "The results from PIONEER 5 showed that oral semaglutide is efficacious and has a solid safety profile in people with type 2 diabetes and moderate renal impairment, thereby further expanding the solid clinical profile of oral semaglutide," said Mads Krogsgaard Thomsen, executive vice president and chief science officer of Novo Nordisk.
