Ingelheim, Germany – Boehringer Ingelheim today announces the start of a Phase II clinical trial evaluating its investigational triple GLP-1/GIP/NPY2 receptor agonist, BI 3034701, in patients with obesity and overweight.1 The trial represents a significant milestone for Boehringer’s cardiometabolic and obesity pipeline, which aims to address obesity as a central driver of interconnected cardiovascular, renal and metabolic conditions.5,6

Obesity is a complex, chronic disease that impacts more than 1 in 8 people worldwide in many different ways, and can have serious long-term consequences.7,8 Due to the heterogeneity of the disease, different mechanisms are needed to address different patient needs, disease stages, and risk profiles.8,9
BI 3034701 is a potential first-in-class triple agonist designed to activate the GLP‑1, GIP, and NPY2 receptors.1 By engaging these three complementary biological pathways, the molecule aims to address obesity through simultaneously targeting the regulation of body weight and metabolism.2,3,4 While the impact of GLP-1 and GIP on satiety, weight, and metabolic regulation is well established,2 NPY2R agonism provides a potentially differentiated mechanism that is still being investigated. Based on scientific literature, activation of the NPY2 receptor modulates central hunger signaling, while its impact on broader eating behavior remains to be fully elucidated.4
In Phase I studies, BI 3034701 demonstrated a generally favorable safety and tolerability profile,10 a key factor in advancing the program into its next phase of clinical development. The Phase II study is designed to evaluate the molecule in people living with obesity and overweight, including dose finding and broader clinical evaluation of efficacy and safety.1
“The obesity treatment landscape is rapidly expanding, with a need to target a broader variety of therapeutic mechanisms given that obesity is a heterogeneous disease. This approach may better enable healthcare providers to move towards matching the right treatment to the right patient at the right time,” said Dr Ania Jaestreboff MD, PhD, professor at Yale School of Medicine and Director of the Yale Obesity Research Center (Y-Weight).
“At Boehringer Ingelheim, we are working towards a future where earlier, multi-pathway intervention leads to long-term outcomes that prevent the progression of interconnected cardiometabolic diseases,” said Shashank Deshpande, Chairman of the Board of Managing Directors and Head of Human Pharma, Boehringer Ingelheim. “In the future, we expect obesity care to become much more differentiated, and with BI 3034701, we aim to go beyond short-term weight loss and address both the biological and behavioral drivers of obesity.”
BI 3034701 is part of a broader portfolio of therapies being developed for people living with obesity or obesity and connected metabolic health conditions, which has multiple approaches under investigation, including survodutide, a dual glucagon/GLP-1 agonist. Results from Phase III trials of survodutide were recently presented at American Diabetes Association’s (ADA) 2026 Scientific Sessions.11 Boehringer Ingelheim’s pipeline across obesity and liver health also includes additional next-generation therapies and experimental approaches including oral treatment options.12

About obesity and overweight
In 2016, more than 1.9 billion adults lived with overweight — defined as a body mass index (BMI) of 25 or more.13 Of these, over 650 million were living with obesity — defined as a BMI of 30 or more.13 More than one billion people around the world are living with obesity today (1 in 8 of us) — and by 2030, that number could be more than double what it was in 2010.14 Overweight and obesity are complex chronic conditions involving abnormal or excessive fat accumulation that present a risk to a person’s overall health.8
