Ascletis Pharma Presents Promising Data for Novel Obesity Treatments at ADA 2026
Ascletis Pharma Inc. (HKEX: 1672) is set to present compelling preclinical and clinical data at the American Diabetes Association’s (ADA) 2026 Scientific Sessions, taking place June 5–8 in Recent Orleans, Louisiana. The presentations spotlight the company’s innovative pipeline of oral little molecule therapeutics targeting obesity and metabolic diseases.
ASC39: A Potential Game-Changer in Amylin Receptor Agonism
A late-breaking poster presentation will detail the preclinical data for ASC39, an oral small molecule amylin receptor agonist. According to the company, ASC39 demonstrates selectivity and potency comparable to eloralintide, a currently available amylin peptide analog. In head-to-head cyclic adenosine monophosphate (cAMP) activation assays, the EC50 for human amylin 1 receptor (hAMY1R) was 21.4 pM for ASC39 and 21.2 pM for eloralintide. Similarly, the EC50 for human calcitonin receptor (hCTR) was 846.1 pM and 1,350.8 pM, respectively, indicating similar selectivity for hAMY1R over hCTR.
This is significant because amylin receptor agonists function by slowing gastric emptying, increasing satiety, and reducing food intake. The development of an oral small molecule agonist like ASC39 could offer a more convenient and potentially more accessible treatment option compared to injectable peptide analogs.
ASC30 Shows Promising Weight Loss and GI Tolerability
Data from a U.S. Phase II study of ASC30, an oral GLP-1R agonist, will also be presented. The study demonstrated a placebo-adjusted weight loss of 7.7% in participants with obesity. Importantly, ASC30 exhibited better gastrointestinal tolerability than orforglipron, with half the rate of vomiting observed during weekly titration.
GLP-1R agonists are a well-established class of drugs for weight management, but many currently available options require injection. An oral formulation with improved tolerability could broaden access and adherence to these therapies.
ASC37 Demonstrates Oral Bioavailability
Ascletis will also present data on ASC37, an oral tablet containing a GLP-1R/GIPR/GCGR triple agonist peptide. Nonhuman primate studies showed an average absolute oral bioavailability of 4.2%.
Even as 4.2% bioavailability may seem low, it represents a significant step forward for peptide-based therapeutics, which traditionally have very poor oral absorption. Ascletis’ Peptide Oral Transport ENhancement Technology (POTENT) appears to be playing a role in improving this delivery method.
The Rise of Oral Obesity Therapeutics
The data presented by Ascletis Pharma aligns with a broader trend in the pharmaceutical industry: the pursuit of effective and convenient oral therapies for obesity. Historically, obesity treatment has been limited by the need for injections or invasive procedures. The development of oral small molecule and peptide-based options is poised to revolutionize the field.
The company is also developing ASC30_39 FDC, a fixed-dose combination of ASC30 and ASC39, expected to enter clinical development with an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) in the third quarter of 2026. This combination approach aims to leverage the complementary mechanisms of action of GLP-1R and amylin receptor agonists for enhanced weight loss and metabolic benefits.
Pro Tip:
Keep an eye on fixed-dose combination therapies. Combining different mechanisms of action in a single pill can often lead to synergistic effects and improved patient outcomes.

Ascletis’ Technology Platforms
Ascletis Pharma’s success is built on its proprietary technology platforms, including Artificial Intelligence-assisted Structure-Based Drug Discovery (AISBDD) and Ultra-Long-Acting Platform (ULAP). These technologies enable the company to efficiently identify and develop novel drug candidates with optimized properties.
FAQ
Q: What is an amylin receptor agonist?
A: An amylin receptor agonist is a type of medication that mimics the effects of amylin, a hormone naturally produced by the pancreas. It helps regulate appetite and food intake.
Q: What is a GLP-1R agonist?
A: A GLP-1R agonist is a medication that activates the glucagon-like peptide-1 receptor, leading to increased insulin secretion, decreased glucagon secretion, and slowed gastric emptying.
Q: When is Ascletis expected to submit an IND application for ASC30_39 FDC?
A: Ascletis expects to submit an IND application to the FDA in the third quarter of 2026.
