MetaVia details DA-1726 data, sets 2026-27 readouts
MetaVia highlights preclinical DA-1726 tissue data that support its once-weekly obesity candidate and tie to earlier waist circumference reductions.
Rhea-AI Filing Summary
MetaVia Inc. (MTVA) reported new preclinical data from its DA-1726 tissue distribution study, showing that DA-1726-derived radioactivity is slowly absorbed and extensively distributed after subcutaneous dosing, with the highest exposure in adipose (fat) tissue and prolonged retention in tissues relative to plasma through the 144-hour assessment.
The company links these findings to previously reported Phase 1 results in obesity, where the 48 mg dose of DA-1726 produced a 9.8 cm mean reduction in waist circumference after eight weeks of treatment. The preclinical profile supports once-weekly dosing and suggests limited brain penetration, with only minimal radioactivity detected in the central nervous system, consistent with peptide-based therapies.
MetaVia states that these data provide mechanistic support for DA-1726’s differentiated profile as a GLP1R/GCGR dual agonist obesity candidate and notes that an ongoing 24-week dose-titration study is underway, with 16-week topline data expected in the fourth quarter of 2026 and 24-week topline results in the first quarter of 2027.

Item 7.01. Regulation FD Disclosures.
On September 9, 2026, MetaVia Inc. (the “Company”) issued a press release announcing results from a preclinical tissue distribution study (the “DA-1726 Study”) demonstrating that DA-1726-derived radioactivity is slowly absorbed and extensively distributed throughout the body following subcutaneous administration, with broad tissue distribution and the highest tissue exposure observed in adipose (fat) tissue. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K (this “Report”) and is incorporated herein by reference.
Information contained on or accessible through any website reference in the press release is not part of, or incorporated by reference in, this Report, and the inclusion of such website addresses in this Report by incorporation by reference of the press release is as inactive textual references only.
The information in Item 7.01 of this Report, including Exhibit 99.1 attached hereto, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing. The Company’s submission of this Report shall not be deemed an admission as to the materiality of any information required to be disclosed solely to satisfy the requirements of Regulation FD.
Item 8.01. Other Events.
On September 9, 2026, the Company announced results from its DA-1726 Study, demonstrating that DA-1726-derived radioactivity is slowly absorbed and extensively distributed throughout the body following subcutaneous administration, with broad tissue distribution and the highest tissue exposure observed in adipose (fat) tissue. The DA-1726 Study showed that tissue-to-plasma ratios increased over time, indicating prolonged retention of DA-1726-derived radioactivity in tissues relative to plasma. Consistent with this finding, the DA-1726 Study also showed that the greatest exposure outside of the injection site occurred in abdominal, subcutaneous and brown fat, as well as the liver. The DA-1726 Study also demonstrated prolonged retention of DA-1726-derived radioactivity in tissues through the final 144-hour assessment, consistent with the prolonged pharmacokinetic profile supporting once-weekly dosing of DA-1726. In addition, the DA-1726 Study demonstrated that only minimal radioactivity was detected in the central nervous system, consistent with the limited brain penetration typically observed with peptide-based therapies.

MetaVia Announces Preclinical Findings Supporting Biological Rationale for DA-1726's Waist Circumference Reduction
Tissue Distribution Study Shows Highest Exposure in Adipose Tissue and Prolonged Retention Consistent with Once-Weekly Dosing Findings Provide Mechanistic Support for the Differentiated Profile of DA-1726
CAMBRIDGE, Mass., September 9, 2026 – MetaVia Inc. (Nasdaq: MTVA), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced results from a preclinical tissue distribution study demonstrating that DA-1726-derived radioactivity is slowly absorbed and extensively distributed throughout the body following subcutaneous administration, with broad tissue distribution and the highest tissue exposure observed in adipose (fat) tissue.
Data from the study showed that tissue-to-plasma ratios increased over time, indicating prolonged retention of DA-1726-derived radioactivity in tissues relative to plasma. Consistent with this finding, the greatest exposure outside of the injection site occurred in abdominal, subcutaneous and brown fat, as well as the liver.
“We believe these findings provide important mechanistic support for the differentiated profile we continue to observe with DA-1726,” stated Hyung Heon Kim, President and Chief Executive Officer of MetaVia. "In our previously reported Phase 1 study, patients receiving the 48 mg dose of DA-1726 achieved a mean reduction in waist circumference of 9.8 cm after only eight weeks of treatment (Day 54). We believe the preferential distribution of DA-1726-derived radioactivity to adipose tissue observed in this preclinical study provides an important biological rationale that is consistent with these encouraging clinical findings. In addition, the prolonged retention of DA-1726-derived radioactivity in tissues observed throughout the study may contribute to the sustained pharmacokinetic exposure of DA-1726 and may also help explain the excellent tolerability profile observed across our clinical studies, to date. Together, these findings further reinforce our confidence in the unique potential of DA-1726 as a next-generation obesity therapy. As patients in our ongoing 24-week dose-titration study continue to receive extended treatment at their highest achieved dose levels, we look forward to evaluating whether longer treatment can further enhance reductions in waist circumference, weight loss and other important cardiometabolic measures. We anticipate reporting 16-week topline data in the fourth quarter of this year, followed by 24-week topline results in the first quarter of 2027."
The preclinical study data also demonstrated prolonged retention of DA-1726-derived radioactivity in tissues through the final 144-hour assessment, consistent with the prolonged pharmacokinetic profile supporting once-weekly dosing of DA-1726. In addition, only minimal radioactivity was detected in the central nervous system, consistent with the limited brain penetration typically observed with peptide-based therapies.
About DA-1726
DA-1726 is a novel GLP1R/GCGR dual agonist for the treatment of obesity and Metabolic Dysfunction-Associated Steatohepatitis (MASH) that is to be administered once weekly subcutaneously. DA-1726 acts as a dual agonist of GLP-1 receptors (GLP1R) and glucagon receptors (GCGR), leading to weight loss through reduced appetite and increased energy expenditure. DA-1726 has a well understood mechanism and, in preclinical mouse models, resulted in improved weight loss compared to semaglutide (Wegovy®),
a leading GLP-1 receptor agonist. Additionally, in preclinical mouse models, DA-1726 elicited similar weight reduction, while consuming more food, compared to tirzepatide (Zepbound®) and survodutide (a drug with the same MOA), while also preserving lean body mass and demonstrating improved lipid-lowering effects compared to survodutide. In the Phase 1 multiple ascending dose (MAD) trial in obesity, the 32 mg dose of DA-1726 demonstrated best-in-class potential for weight loss, glucose control, and waist circumference reduction.
About MetaVia
MetaVia Inc. is a clinical-stage biotechnology company focused on transforming cardiometabolic diseases. The company is currently developing DA-1726 for the treatment of obesity, and is developing vanoglipel (DA-1241) for the treatment of Metabolic Dysfunction-Associated Steatohepatitis (MASH). DA-1726 is a novel oxyntomodulin (OXM) analogue that functions as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR) dual agonist. OXM is a naturally-occurring gut hormone that activates GLP1R and GCGR, thereby decreasing food intake while increasing energy expenditure, thus potentially resulting in superior body weight loss compared to selective GLP-1 receptor agonists such as semaglutide. In a Phase 1 multiple ascending dose (MAD) trial in obesity, DA-1726 demonstrated best-in-class potential for weight loss, glucose control, and waist reduction. Vanoglipel is a potential first-in-class drug candidate targeting G-protein-coupled receptor 119 (GPR119). In preclinical studies, vanoglipel demonstrated a positive metabolic effect on glucose and lipid control, and also proved differentiated hepatic benefits reducing hepatic steatosis, hepatic inflammation, and liver fibrosis regardless independent of metabolic improvement. In a Phase 2a clinical study, vanoglipel demonstrated direct hepatic action in addition to its glucose lowering effects.
