Survodutide (BI 456906); dual glucagon receptor (GCGR) / glucagon-like peptide-1 receptor (GLP-1R) agonist
Investigational drug in Phase 3 clinical trials (Boehringer Ingelheim) for obesity and MASH. Not yet FDA-approved.
An investigational once-weekly injection being developed for obesity and MASH (a serious form of fatty liver disease that can lead to liver damage). A clinical trial showed it resolved the liver condition in 62% of patients versus 14% on placebo, one of the strongest results seen for any fatty liver treatment. This medication is not yet approved.

Survodutide (BI 456906) has substantial clinical evidence but is not FDA-approved.

Gastrointestinal adverse events are the predominant safety concern with survodutide and are a class effect of GLP-1R agonism, compounded by GCGR activity. Incidence is dose-dependent and highest during dose-escalation phases. Titration strategies are used in all clinical protocols to mitigate GI tolerability. Overall AE rates were 91% survodutide vs 75% placebo in one dose-finding trial. SAE rates (4-8%) were similar to placebo. Treatment discontinuation due to AEs was 15-25%, predominantly due to GI events. No clinically important immunogenicity (anti-drug antibody) signal was reported PMC12184113. Preclinical carcinogenicity studies showed thyroid C-cell tumors in rodents (class effect for GLP-1R agonists) at high exposures; no signal in non-rodent species (monkey), and no human pharmacovigilance cancer signal through early 2026 (PMC9679702; FAERS data). Preclinical monkey studies showed mild myocardial changes (vacuolation) at supratherapeutic doses with identified NOAEL PMC9679702. No clinical QT signal reported. Pharmacodynamic drug interaction risk: delayed gastric emptying may alter absorption of narrow-therapeutic-index oral drugs (DrugBank DB18989; PMC12052016). Long-term tolerance: sustained efficacy through Week 76 without clear tachyphylaxis (PMC12803687; dom DOI 10.1111/dom.70196). Withdrawal: no dedicated discontinuation trials; class-level evidence suggests metabolic/weight rebound after stopping GLP-1 therapy (Lancet eClinicalMedicine DOI S2589-5370(25)00614-5) (NEJM DOI 10.1056/NEJMoa2401755; PMC10844353; PMC9679702; PMC12184113).
If real-world use or exposure is being considered, review potential interactions, contraindications, and monitoring needs with a licensed clinician rather than relying on summary copy alone.
