[Citations](#citations) ## What It Is Tirzepatide is a first-in-class dual incretin agonist that activates both the GIP and GLP-1 receptors. FDA-approved under the brand names Mounjaro (diabetes) and Zepbound (weight management), it has demonstrated significant weight loss and glycemic control in clinical trials. In 2026, tirzepatide received FDA approval for metabolic dysfunction-associated steatohepatitis (MASH) with liver fibrosis stages F2 or F3 — becoming the second FDA-approved pharmacotherapy for MASH after resmetirom (Rezdiffra). The SYNERGY-NASH Phase 2 trial showed 51.8%, 62.8%, and 73.3% of participants on 5 mg, 10 mg, and 15 mg doses achieved MASH resolution with no worsening of fibrosis at 52 weeks, compared to 13.2% on placebo. Additionally, 59.1%, 53.3%, and 54.2% of participants across doses achieved 1-stage or greater fibrosis improvement without worsening of MASH versus 32.8% on placebo. The FDA granted breakthrough therapy designation for this indication. In a landmark head-to-head trial published in the New England Journal of Medicine (2025), tirzepatide was shown to be superior to semaglutide with respect to body weight reduction: the mean percent change in weight at week 72 was −20.2% with tirzepatide versus −13.7% with semaglutide, with tirzepatide also producing greater waist circumference reductions. The SURMOUNT trial series showed average weight loss of 20–25% of body weight in some cohorts. In the Phase 3 SURMOUNT-OSA trial, tirzepatide demonstrated a reduction of 25.3 to 29.3 events per hour in apnea-hypopnea index versus approximately 5 with placebo, alongside 17–20% body weight reduction — establishing a potential role in treating obesity-related obstructive sleep apnea. Tirzepatide is also in clinical trials for autoimmune conditions in adults with obesity — notably, Phase 3 trials combining tirzepatide with ixekizumab (Taltz) for plaque psoriasis and psoriatic arthritis in patients with obesity are expected to complete in the first half of 2026. Mounjaro is under FDA review for a new indication to reduce the risk of major adverse cardiovascular events (MACE) in patients with type 2 diabetes, with a decision expected in early-to-mid 2026. Tirzepatide monotherapy is also in clinical trials for type 1 diabetes (estimated completion 2027). The Phase 3 SUMMIT trial demonstrated that tirzepatide reduced the composite risk of cardiovascular death or worsening heart failure by 38% in adults with heart failure with preserved ejection fraction (HFpEF) and obesity over a median follow-up of approximately 2 years. Participants showed significant improvements in physical function, exercise tolerance, weight loss, and reduced systemic inflammation. While tirzepatide is not yet FDA-approved for HFpEF, these results position it as a potential first incretin therapy for obesity-related heart failure, with regulatory submission anticipated. A May 2026 meta-analysis of over 90,000 participants across multiple GLP-1 RA clinical trials confirmed that the GLP-1 receptor agonist class — including both semaglutide and tirzepatide — significantly reduces cardiovascular events including heart attacks, strokes, and heart failure hospitalization, further reinforcing the cardiometabolic benefits of incretin-based therapies. The Medicare GLP-1 Bridge program, launching July 1, 2026, covers Zepbound (KwikPen) for eligible Medicare Part D beneficiaries at a $50/month copayment — representing a major access expansion for one of the most effective obesity treatments available. The program runs through December 31, 2027, and is administered outside the standard Part D benefit, meaning copayments remain flat at $50 regardless of benefit phase. Alongside Foundayo and Wegovy, Zepbound is one of only three medications designated by CMS for the bridge program. Also known as: Mounjaro, Zepbound ## Regulatory Status FDA-Approved (T2D, obesity, MASH) FDA-approved as Mounjaro for type 2 diabetes (May 2022), as Zepbound for chronic weight management (November 2023), and for MASH with moderate-to-advanced fibrosis (early 2026). 73.3% of patients taking 15 mg achieved MASH resolution at 52 weeks in SYNERGY-NASH. SUMMIT trial for HFpEF with obesity submission anticipated.

CT-388 is engineered as a 'signal-biased' agonist: it potently activates both incretin receptors but recruits little or no beta-arrestin, which is expected to reduce receptor internalization and desensitization and thereby prolong pharmacological activity. In a Phase 1b study it produced ~18.8% placebo-adjusted weight loss at 24 weeks, and in the Phase 2 CT388-103 dose-finding trial (469 adults with obesity/overweight) it delivered a placebo-adjusted mean weight loss of 22.5% at 48 weeks (efficacy estimand; 18.3% treatment-regimen estimand) at the top 24 mg dose, without reaching a plateau. Roche advanced CT-388 into Phase 3 in the first half of 2026, positioning it as a late-entrant competitor to tirzepatide (Zepbound) with a potentially differentiated biased-signaling mechanism.

It is built on Hanmi's LAPSCovery platform as a chemical conjugate of a chimeric tri-agonist peptide (TA15211) fused to a human IgG4 Fc fragment, which extends its half-life via FcRn-mediated recycling and enables weekly subcutaneous dosing. By adding glucagon-receptor activation to the GLP-1/GIP dual mechanism, efocipegtrutide is designed to combine appetite suppression and glycemic control with increased energy expenditure and direct hepatic anti-steatotic, anti-inflammatory, and anti-fibrotic effects. In a Phase 1b/2a study in obese subjects with non-alcoholic fatty liver disease, 12 weeks of treatment reduced liver fat by roughly 20% to 59% (dose-dependent, MRI-PDFF) versus about 6% on placebo. It has FDA Fast Track designation for MASH and orphan-drug designations from the FDA and EMA for primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and idiopathic pulmonary fibrosis (IPF). The 52-week adaptive Phase 2 HM-TRIA-201 study (NCT04505436) in biopsy-confirmed MASH with fibrosis is the pivotal read the field is watching.

That design lets one subcutaneous injection lower blood sugar, curb appetite and reduce body weight for a full week. Efpeglenatide is best known for the landmark AMPLITUDE-O cardiovascular outcomes trial (NEJM 2021), in which 4,076 people with type 2 diabetes and cardiovascular or kidney disease had a 27% lower rate of major adverse cardiovascular events (MACE hazard ratio 0.73) and a 32% lower rate of a composite kidney outcome (hazard ratio 0.68) versus placebo - the first cardiovascular outcomes win for an exendin-based GLP-1 and one of the clearest kidney signals in the class, with benefit seen regardless of whether patients were also taking an SGLT2 inhibitor. Originally licensed to Sanofi and then returned to Hanmi in 2020, efpeglenatide is now being advanced primarily for obesity and overweight, with a Phase 3 program that has completed enrollment and a targeted first launch in South Korea in the second half of 2026. It is an investigational (not yet approved) prescription medicine, not a supplement or research chemical.

It is a bivalent Fc-FGF21 fusion protein - two engineered FGF21 sequences fused to a human immunoglobulin (IgG1) Fc domain - a design distinct from the glycoPEGylation used by its main FGF21-class rival, pegozafermin. The Fc fusion extends the very short half-life of native FGF21 to support once-weekly dosing while preserving agonism at FGF receptors (FGFR1c/2c/3c) together with the co-receptor beta-Klotho. In the 96-week Phase 2b HARMONY trial in biopsy-confirmed F2-F3 MASH, at least a one-stage improvement in fibrosis without worsening of MASH was reached by about 75% of patients on 50 mg and 46% on 28 mg versus 24% on placebo (published in The Lancet, August 2025). In the Phase 2b SYMMETRY trial in compensated MASH cirrhosis, about 39% of 50 mg patients with paired week-96 biopsies achieved reversal of cirrhosis without worsening of MASH versus 15% on placebo (published in the New England Journal of Medicine). Efruxifermin holds FDA Breakthrough Therapy designation and has advanced into the Phase 3 SYNCHRONY program (SYNCHRONY Histology in F2-F3 MASH, SYNCHRONY Outcomes in F4 compensated cirrhosis, and SYNCHRONY Real-World in non-invasively diagnosed MASH/MASLD, whose double-blind portion completed enrollment with safety results expected in 2026).

Developed by Eli Lilly (code LY3209590, also called basal insulin Fc or BIF), efsitora is designed to replace daily long-acting insulin with a flat, ultra-stable weekly profile. In the large Phase 3 QWINT program it matched daily insulins glargine and degludec on A1C in type 2 diabetes, and in insulin-naive patients its simplified fixed-dose titration cut the number of dose adjustments dramatically while keeping hypoglycemia low. In type 1 diabetes (QWINT-5) it was non-inferior on A1C but showed a higher rate of severe hypoglycemia, a key safety caveat. As of mid-2026 efsitora is under FDA review for type 2 diabetes (a decision expected in the third quarter of 2026) and would compete directly with Novo Nordisk's once-weekly insulin icodec (Awiqli).

Originally developed by 89bio and acquired by Roche in a deal announced in September 2025 (about $2.4 billion upfront and up to roughly $3.5 billion including a contingent value right), it uses site-specific glycoPEGylation to extend the very short half-life of native FGF21 to roughly 55-100 hours, enabling once-weekly or once-every-two-weeks subcutaneous dosing. FGF21 is a metabolic hormone that acts on liver, fat, and other tissues to improve insulin sensitivity, lower triglycerides, and exert direct anti-fibrotic and anti-inflammatory effects. In the Phase 2b ENLIVEN trial in biopsy-confirmed F2-F3 MASH, the 44 mg every-two-weeks dose produced at least a one-stage fibrosis improvement without worsening of MASH in about 27% of patients versus 7% on placebo, and MASH resolution without worsening of fibrosis in about 26% versus 2% on placebo, with benefits sustained through week 48. Pegozafermin holds FDA Breakthrough Therapy designation and EMA PRIME status for MASH and has advanced into the Phase 3 ENLIGHTEN program (ENLIGHTEN-Fibrosis in non-cirrhotic F2-F3 MASH and ENLIGHTEN-Cirrhosis in compensated F4 cirrhosis), plus the Phase 3 ENTRUST trial in SHTG.
