Survodutide
clinical trialsAlso known as: BI 456906
**Mechanism of Action** Survodutide (BI 456906) is a synthetic dual agonist of the glucagon receptor (GCGR) and glucagon-like peptide-1 receptor (GLP-1R). By simultaneously activating both receptors, it enhances energy expenditure via glucagon-mediated thermogenesis and lipolysis while reducing appetite and delaying gastric emptying through GLP-1 signaling. This dual mechanism aims to achieve greater weight loss and metabolic improvements than selective GLP-1 agonists alone. **Key Research Findings** Phase 2 trials demonstrated significant dose-dependent weight reduction in adults with obesity, with mean losses up to 18.7% at 46 weeks (vs. 2.0% placebo). In MASH (metabolic dysfunction-associated steatohepatitis), a Phase 2 study showed 83% of patients achieving MASH resolution without worsening fibrosis at 48 weeks (vs. 18.2% placebo). Common adverse events include gastrointestinal effects (nausea, vomiting), consistent with GLP-1 agonism. Phase 3 trials (SYNCHRONIZE program) are ongoing for obesity and MASH. **Clinical Relevance** Survodutide represents a promising next-generation incretin-based therapy for obesity and MASH, potentially offering superior efficacy over selective GLP-1 agonists. Its dual mechanism may address both weight loss and liver histology endpoints. Regulatory approval decisions await Phase 3 outcomes. For research purposes only — not medical advice.

Mean weight change at week 76 was -12.2% (3.6 mg), -13.0% (6.0 mg), and -5.4% (placebo).; At least 5% weight reduction occurred in 72.6% (3.6 mg), 71.9% (6.0 mg), and 46.3% (placebo) of participants (P<0.001 vs placebo).; Gastrointestinal symptoms were the most common adverse events, occurring in 80.9% (3.6 mg), 89.7% (6.0 mg), and 47.9% (placebo) of participants; no deaths were reported.
84.2% of survodutide-treated patients vs 24.3% of placebo-treated patients achieved a 30% reduction in liver fat content (efficacy estimand; P < 0.0001); Mean body weight change was -12.2% with survodutide vs -1.0% with placebo (efficacy estimand; P < 0.0001); Most frequent adverse events with survodutide were gastrointestinal, commonly during dose escalation, and generally mild-to-moderate; Limitations included short trial duration (48 weeks) and recruitment limited to the United States and Spain
Next-generation agents engage GLP-1, GIP, glucagon, amylin, and peptide YY receptors to enhance energy uptake, storage, and expenditure.; Maridebart cafraglutide combines GLP-1 receptor agonism with GIP receptor antagonism, showing promise.; Glucagon coagonists like survodutide and mazdutide demonstrate significant weight loss and improved glycemic control.; Orally active small-molecule GLP-1 receptor agonists such as danuglipron and orforglipron are resistant to enzymatic degradation, advancing patient-friendly drug delivery.
Participants (n=725) had a mean BMI of 37.9 kg/m² and waist circumference of 115.2 cm.; Most participants were female (59.4%), with 47.3% from North America, 21.0% from Europe, and 20.0% from East Asia.; Common obesity complications at baseline included hypertension (40.0%), dyslipidaemia (33.7%), and prediabetes (30.2%).; Mean HbA1c was 5.5%, and 21.8% were taking lipid-lowering drugs.
Pegozafermin, cilofexor + firsocostat, and denifanstat were significantly better than placebo for fibrosis regression without MASH worsening.; Pegozafermin, survodutide, and tirzepatide were the most effective for MASH resolution without worsening fibrosis.; SUCRA rankings identified pegozafermin as top for both fibrosis regression (79.92) and MASH resolution (91.75).; Eight agents significantly improved fibrosis regression, while twelve agents significantly improved MASH resolution versus placebo.
Current therapies for DM and CKD encompass five drug classes: ACEI/AIIRB, SGLT2 inhibitors, GLP-1 RA, ET1R antagonists, and the MRA finerenone.; Finerenone has been tested in RCTs as a kidney protective agent.; Novel agents in development include balcinrenone, baxdrostat, vicadrostat, tirzepatide, survodutide, retatrutide, cagrilintide, zibotentan, and avenciguat.; Future strategies rely on integrated, patient-centered approaches and personalized therapy to curb renal disease and its complications.
GLP-1 receptor agonists (e.g., semaglutide) achieve 15-17% weight loss with a good safety profile.; Tirzepatide, a dual GLP-1/GIP agonist, achieves up to 22.5% weight loss at highest doses.; Combinations like Cagrisema and Retatrutide are expected to achieve similar weight loss ranges.; New drugs target gastroenteropancreatic hormones to improve cardiometabolic variables.
Retatrutide and dual agonists achieved equivalent mean weight loss (-11.0 kg), surpassing GLP-1RAs (-9.0 kg).; Retatrutide had the highest odds of achieving 15% weight loss (OR 54.6), followed by dual agonists (OR 16.4) and GLP-1RAs (OR 9.0).; Retatrutide had the highest adverse event risk, while dual agonists offered a favorable efficacy-safety balance.; Type 2 diabetes mellitus reduced weight loss by 4.338 kg for GLP-1RAs and 5.016 kg for dual agonists, with enhanced outcomes in female-dominant or high-BMI cohorts.
