Key Findings
- Oral semaglutide (25 mg/50 mg) and the non‑peptide oral GLP‑1 RA orforglipron show strong glucose‑lowering and weight‑loss effects in phase 3 studies.
- Dual agonist tirzepatide (GLP‑1/GIP) is already approved and delivers up to 15% body‑weight loss plus good blood‑sugar control.
- The cagrilintide + semaglutide 2.4 mg combo (a triple‑agonist approach) achieved ≥15% weight loss and euglycemia in phase 3 trials for type 2 diabetes.
- Cardio‑renal outcomes and long‑term safety are still being collected, but early data are encouraging.
Practical Outcomes
- For biohackers, expect oral GLP‑1 options to hit the market soon, offering a non‑injectable way to improve insulin sensitivity and lose fat. The cagrilintide‑based combos could become the next high‑potency tool for rapid, sustained weight loss and glucose control once approved. Keep an eye on trial updates and be ready to integrate these agents into self‑experiment protocols when they become available.
Summary
New oral GLP‑1 pills (like oral semaglutide and the experimental orforglipron) and combo drugs that hit several gut hormones (such as tirzepatide and the cagrilintide + semaglutide mix) are now in late‑stage trials. They can lower blood sugar, cut weight by 15% or more, and may bring heart‑kidney benefits, all without the need for daily injections.
Abstract
Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) have changed the landscape of type 2 diabetes (T2D) management due to their cardio-renal benefits, their glucose-lowering efficacy and weight loss (WL) maintenance. However, the response to GLP-1 RA monotherapy is heterogeneous. Additionally, the majority of GLP-1 RAs are injectable treatments. Oral GLP-1 RAs and injectable combinations of GLP-1 with other entero-pancreatic hormones (glucose-dependent insulinotropic polypeptide (GIP), glucagon and amylin) are under development for T2D and obesity management. Herein, we review the data on (i) oral GLP-1 RAs (oral semaglutide 25/50 mg and orforglipron) and (ii) dual/triple agonists (tirzepatide, cagrilintide 2.4 mg/semaglutide 2.4 mg, survodutide, mazdutide, retatrutide) that have recently completed phase 3 trials for T2D or are currently in phase 3 clinical trials. Tirzepatide is the first approved dual agonist (GLP-1/GIP) for T2D and obesity management. We are in a new era in T2D management where entero-pancreatic hormone-based treatments can result in ≥15% WL and euglycemia for many people with T2D. Multiple molecules with different mechanisms of action are under development for T2D, obesity and other metabolic complications. Data on their cardio-renal benefits, long-term efficacy and safety as well as their cost-effectiveness will better inform their position in treatment algorithms.
