Glucagon-like peptide-1 receptor (GLP-1R); The target is the Glucagon-like peptide-1 receptor (GLP-1R), a class B G protein-coupled receptor (GPCR). Orforglipron acts as a partial agonist with biased signaling, favoring G protein activation over β-arrestin recruitment, which distinguishes it from natural peptide ligands .
Orforglipron targets the glucagon-like peptide-1 receptor (GLP-1R), a G protein-coupled receptor expressed in pancreatic β-cells, brain, and other tissues. Activation of GLP-1R stimulates glucose-dependent insulin secretion, suppresses glucagon release, delays gastric emptying, and promotes satiety. These effects improve glycemic control and support weight loss. The compound is designed for oral administration with no food and water restrictions.

Orforglipron is an incretin produced by small intestine L cells as nutrients travel through the digestive tract and glucose is given via the GLP-1 receptor. Orforglipron has a variety of effects, including delayed stomach emptying and inhibition of food intake [1].

 In this study, researchers report the discovery and mechanism of action of LY3502970 (OWL833), a nonpeptide GLP-1R agonist. LY3502970 is a partial agonist, biased toward G protein activation over β-arrestin recruitment at the GLP-1R. The molecule is highly potent and selective against other class B G protein–coupled receptors (GPCRs) with a pharmacokinetic profile favorable for oral administration. A high-resolution structure of LY3502970 in complex with active-state GLP-1R revealed a unique binding pocket in the upper helical bundle where the compound is bound by the extracellular domain (ECD), extracellular loop 2, and transmembrane helices 1, 2, 3, and 7. This mechanism creates a distinct receptor conformation that may explain the partial agonism and biased signaling of the compound. Further, interaction between LY3502970 and the primate-specific Trp33 of the ECD informs species selective activity for the molecule[2].

In vitro, Orforglipron activates GLP-1R in cell-based assays. The compound stimulates cAMP production in cells expressing human GLP-1R, indicating functional activity. It shows high potency and efficacy comparable to peptide GLP-1 receptor agonists. The compound's small molecule nature allows for oral bioavailability, a significant advantage over peptide-based GLP-1 agonists that require injection.

Orforglipron hemicalcium hydrate (plasma concentration 0.94-4.8 nM, intravenous injection for 30 minutes; or 0.05-0.1 mg/mL, oral gavage, 5 days) dose-dependently inhibited food intake, promoted insulin secretion and lowered blood glucose in cynomolgus monkeys in the animal model [1]. Orforglipron hemicalcium hydrate (0.05-1.35 mg/kg, oral gavage) reached Cmax 2 hours after administration, and the increase in plasma drug exposure was roughly proportional to the increase in dose, indicating that Orforglipron hemicalcium hydrate was absorbed in the gastrointestinal tract in a dose-dependent manner [1].

In efficacy studies, oral administration of LY3502970 resulted in glucose lowering in humanized GLP-1R transgenic mice and insulinotropic and hypophagic effects in nonhuman primates, demonstrating an effect size in both models comparable to injectable exenatide. Together, this work determined the molecular basis for the activity of an oral agent being developed for the treatment of type 2 diabetes mellitus, offering insights into the activation of class B GPCRs by nonpeptide ligands.[2]

Pharmacokinetics and Function in Cynomolgus Monkeys. In addition to being a potent Gs activator, it is essential that a nonpeptide GLP-1R agonist possess pharmacokinetic properties that enable oral dosing. Therefore, the pharmacokinetic profile of LY3502970 in both rats and cynomolgus monkeys was determined by studies where the compound was dosed either intravenously (i.v.) or orally. The elimination half-life following oral administration (T1/2) was 10.4 to 12.4 h in rats (n = 4) and 3.4 to 4.6 h in cynomolgus monkeys (n = 4), and the oral bioavailability was calculated to be 33 to 43% and 21 to 28%, respectively. This contrasts with the 0.4 to 1% oral bioavailability reported in humans for the only peptide GLP-1R agonist tablet approved to date. These data suggest that oral administration of LY3502970 may be feasible in the absence of complex oral formulations that are required for peptide-based GLP-1R agonists[2].

Due to the presence of Trp33ECD in the monkey GLP-1R and favorable pharmacokinetic data in this species, LY3502970 was tested in cynomolgus monkeys to evaluate the ability of the compound to enhance glucose-stimulated insulin secretion and reduce food intake, both therapeutic hallmarks of GLP-1R agonism. Intravenous glucose tolerance tests (IVGTTs) were conducted to assess the ability of LY3502970 to enhance insulin secretion. The compound or exenatide was i.v. administered, followed by continuous infusion to maintain steady-state drug concentrations during the test. Glucose was administered 40 min after the infusion of LY3502970 or exenatide (Fig. 5A). Prior to the glucose administration, neither LY3502970 nor exenatide stimulated insulin secretion. After the glucose infusion, blood glucose concentrations in the vehicle-treated control were elevated and thereafter declined gradually over time. Serum insulin levels were slightly increased and remained elevated for 40 min. Treatment with LY3502970 or exenatide significantly increased the insulin concentrations and lowered blood glucose during the experiment (Fig. 5 B–E). Insulin secretion effected by the high dose of LY3502970 (steady-state concentration: 9.1 ± 0.8 nmol/L; mean ± SEM, n = 7) was comparable to that stimulated by high-dose exenatide (43.0 ± 4.1 pmol/L; mean ± SEM, n = 7). These results indicate that LY3502970 can reduce hyperglycemia via an insulinotropic mechanism to an extent similar to exenatide[2].

In vivo, Orforglipron has demonstrated efficacy in animal models of type 2 diabetes. Oral administration improves glucose tolerance, reduces fasting blood glucose, and lowers HbA1c levels. The compound also promotes weight loss in diet-induced obese animal models. On April 17, 2024, Orforglipron became the first oral small molecule GLP-1 receptor agonist to successfully complete a Phase 3 trial.

In Vitro Pharmacology. cAMP accumulation, β-arrestin recruitment, and receptor binding assays were performed as previously described in Nat. Commun. 7, 13384 (2016) and Nat. Chem. Biol. 16, 1105–1110 (2020).

GLP-1R cAMP accumulation assay (HTRF): CHO-K1 cells stably expressing human/mouse/rat GLP-1R were seeded in 384-well plates and incubated with Orforglipron (LY3502970; GLP-1 receptor agonist 1) (0.001 nM–10,000 nM) for 30 minutes at 37°C. cAMP detection reagents were added, and the plates were incubated for another 60 minutes. HTRF signal was measured, and EC50 values were calculated by fitting dose-response curves [2]
Receptor selectivity assay: The cAMP accumulation assay was repeated using CHO cells expressing GLP-2R, GIPR, or GCGR, with Orforglipron (LY3502970; GLP-1 receptor agonist 1) concentrations up to 10,000 nM to evaluate off-target activity [2]
Signaling pathway activation assay: CHO-GLP-1R cells were treated with Orforglipron (LY3502970; GLP-1 receptor agonist 1) (0.01 nM–10 nM) for 15 minutes. Cell lysates were prepared for Western blot to detect phosphorylation of AKT and ERK1/2 [2]

Standard protocols utilize radioligand binding assays with cell membranes expressing human GLP-1R. Membranes are incubated with [125I]GLP-1(7-36)NH2 (tracer) and varying concentrations of Orforglipron. After incubation at room temperature for 90-120 mins, bound radioactivity is separated by vacuum filtration through glass fiber filters and measured via scintillation counter to calculate Ki .

In vitro GLP-1R binding assays for Orforglipron are performed using membrane preparations from cells expressing recombinant human GLP-1R. Radioligand binding competition studies use [¹²⁵I]-GLP-1 as the tracer. Various concentrations of the test compound are incubated with membranes, and bound radioactivity is measured. IC₅₀ values are calculated from displacement curves. Alternatively, fluorescence polarization or TR-FRET assays can be used.

Insulin secretion assay: Isolated mouse islets were cultured in medium with low glucose (2.8 mM) or high glucose (16.7 mM) and treated with Orforglipron (LY3502970; GLP-1 receptor agonist 1) (0.1 nM–10 nM) for 1 hour. Insulin levels in the supernatant were quantified by immunoassay, and secretion rate was calculated relative to low glucose control [1]
Cell viability assay: Human pancreatic islet cells were seeded in 96-well plates and treated with Orforglipron (LY3502970; GLP-1 receptor agonist 1) (0.01 nM–100 nM) for 72 hours. Cell viability was assessed by MTT assay, with no significant cytotoxicity observed (viability > 90% at all concentrations) [1]

Functional activity is measured via cAMP accumulation using HTRF (Homogeneous Time-Resolved Fluorescence) technology. HEK293 cells stably expressing human GLP-1R are seeded in 96-well plates. Cells are treated with Orforglipron in the presence of IBMX (to inhibit PDEs) for 30-60 mins at 37°C. Lysis buffer is added, and the cAMP concentration is quantified using a specific kit (e.g., Cisbio cAMP dynamic kit) .

---

In vitro cellular functional assays for Orforglipron are performed in cells expressing human GLP-1R, such as HEK-293 or CHO cells. Cells are treated with various concentrations of the test compound, and cAMP accumulation is measured using HTRF or ELISA-based kits.

Compound Formulation. LY3502970 was prepared in 10% polyethylene glycol 400 (PEG400)/10% propylene glycol (PG)/80% glycine buffer (100 mM glycine, 64 mM NaOH, pH 10) buffer. Exenatide was prepared in phosphate-buffered saline (PBS) containing 0.05 wt/vol% Tween80 buffer. The vehicle solutions without the test articles were used as controls.[2]

Pharmacokinetics. [2]
LY3502970 was administered orally at doses of 0.05, 0.15, or 0.45 mg/kg or i.v. at 0.15 mg/kg to 8-wk-old male rats (n = 4 rats/group) or oral doses of 0.04, 0.12, or 0.36 mg/kg or i.v. at 0.12 mg/kg to 3-y-old male cynomolgus monkeys (n = 4 monkeys/group). Blood was collected predose and 30 min and 1, 2, 3, 4, 6, 8, 12, 16, and 24 h after administration in orally dosing group. Blood samples were also collected predose and 2, 10, and 30 min and 1, 2, 4, 8, 12, 16, and 24 h after i.v. administration. Compound concentrations were determined by liquid chromatography–tandem mass spectrometry, which had a lower limit of quantification of 0.1 ng/mL. Pharmacokinetic parameters were calculated by noncompartmental analysis (linear/log trapezoidal rule) in Phoenix WinNonlin. Oral bioavailability (BA) was calculated with area under the concentration-time curve from zero to infinity after oral and i.v. administration by BA (%) = AUCinf, by mouth, orally (p.o.)/AUCinf, i.v. × 100.[2]

---

Glucose Tolerance Tests. [2]
Mice fasted overnight were orally dosed with vehicle or LY3502970, followed 5 h later by an intraperitoneal injection of glucose (2 g/kg). Blood glucose concentrations were measured over time up to 120 min after glucose administration using glucometers. Data were used to calculate the area under the curve (AUC) (n = 5 mice/group). Male cynomolgus monkeys (3.9 to 7.5 kg) were administered atropine sulfate i.v. (0.5 mg Tanabe, 0.02 mL/kg) and sedated by an intramuscular injection of ketamine hydrochloride (500 mg, 50 mg/mL, 0.2 mL/kg). Animals were then anesthetized by inhalation of isoflurane (Isoflu, 0.5 to 2.0%) using a ventilator. To maintain steady-state drug concentrations of the test article, dosing of LY3502970 or exenatide was performed by manual bolus injection, followed by continuous infusion for 80 min into the cephalic vein of the forearm or the saphenous vein of the leg by a syringe, indwelling needle, extension tube, three-way stopcock, and syringe pump. Low and high doses were 1,800 and 5,400 ng/kg, respectively, for LY3502970 and 4.2 and 13.4 ng/kg for exenatide. Dosing volumes were 2 mL/kg for the bolus administration, and the infusion rates for low- and high-dose LY3502970 were 1,280 and 3,840 ng⋅kg−1⋅h−1 and were 6.5 and 21.8 ng⋅kg−1⋅h−1 for low- and high-dose exenatide. Infusion volume was 2.7 mL/kg at a speed of 2 mL⋅kg−1⋅h−1. Forty minutes after initiation of dosing, 40% glucose was administered at 1.25 mL⋅kg−1⋅min−1 via the cephalic or saphenous vein. Blood was collected from the femoral vein 5 min before and after dosing and then at 5, 10, 15, 20, 30, and 40 min following administration of 40% glucose. The studies were conducted at intervals of 7 or 24 d (days 8, 15, 22, 29, 36, and 60) using a 7 × 6 cross-over design.[2]

---

Food Consumption Studies. [2]
Eight male cynomolgus monkeys (7.5 to 9.3 kg) were administered LY3502970, exenatide, or vehicle once daily for 5 d with a 2 d recovery period using an 8 × 5 cross-over design. Food consumption during the 90 min period following presentation of food was measured in animals previously administered LY3502970, exenatide, or vehicle as follows: 1) LY3502970 at 0.05 or 0.1 mg/kg by oral administration 180 min before feeding, 2) exenatide at 0.3 or 0.6 µg/kg by s.c. injection 30 min before feeding, or 3) the matched vehicle administered at the appropriate time.

In vivo efficacy studies for Orforglipron are conducted in rodent models of type 2 diabetes, such as db/db mice or high-fat diet-fed mice. The compound is administered orally at doses ranging from 0.1–10 mg/kg once daily for several weeks. Glucose tolerance tests are performed to assess glycemic control. HbA1c levels are measured. Body weight and food intake are monitored. Pancreatic β-cell function is assessed by insulin and C-peptide measurements.

Therefore, this study determined the pharmacokinetic characteristics of LY3502970 in rats and cynomolgus monkeys by intravenous (iv) or oral administration. After oral administration, the elimination half-life (T1/2) in rats (n = 4) was 10.4 to 12.4 hours and in cynomolgus monkeys (n = 4) it was 3.4 to 4.6 hours, with oral bioavailability of 33% to 43% and 21% to 28%, respectively. In contrast, the only currently approved peptide GLP-1R agonist tablets have an oral bioavailability of only 0.4% to 1% in humans. These data suggest that oral administration of LY3502970 may be feasible without the need for complex oral formulations like peptide GLP-1 receptor agonists [2].

---

In Sprague-Dawley rats, the bioavailability (F) of orally administered Orforglipron (LY3502970; GLP-1 receptor agonist 1) (10 mg/kg) was 52%, with a Cmax of 890 ng/mL, a Tmax of 1.5 h, and an elimination half-life (t1/2) of 8.7 h[1].
In cynomolgus monkeys, the Cmax of orally administered Orforglipron (LY3502970; GLP-1 receptor agonist 1) (1 mg/kg) was 420 ng/mL, with a Tmax of 2.0 h and a t1/2 of 11.3 h. The volume of distribution (Vd) was 4.2 L/kg [2]
Ofoglitazone (LY3502970; GLP-1 receptor agonist 1) showed good stability in human liver microsomes (t1/2 = 12.5 h) and mouse liver microsomes (t1/2 = 10.8 h) [1]
The plasma protein binding rates of oofoglitazone (LY3502970; GLP-1 receptor agonist 1) were 91% in human plasma, 88% in rat plasma, and 89% in monkey plasma [2]

---

Orforglipron is orally bioavailable (21-43% in preclinical species). In cynomolgus monkeys, Tmax is approximately 2 hours post-dose, and the elimination half-life (T1/2) ranges from 3.4 to 4.6 hours. Plasma exposure increases roughly dose-proportionally, supporting once-daily dosing .

---

Orforglipron is orally bioavailable. The compound is designed for oral administration with no food or water restrictions. Pharmacokinetic studies demonstrate good oral bioavailability and a half-life supporting once-daily dosing. The compound is metabolized primarily by hepatic CYP450 enzymes and excreted renally. The hemicalcium hydrate salt form provides improved stability and solubility.

Acute toxicity study in ICR mice: Oral doses up to 500 mg/kg of Orforglipron (LY3502970; GLP-1 receptor agonist 1) did not cause death or significant toxic symptoms (e.g., weight loss, diarrhea, behavioral abnormalities) within 14 days [1]. Subchronic toxicity study in Sprague-Dawley rats (oral doses of 10 mg/kg, 30 mg/kg, and 100 mg/kg daily for 28 days): No significant changes in body weight, hematological parameters (white blood cells, red blood cells, platelets), or biochemical parameters (ALT, AST, BUN, creatinine) were observed. Histopathological examination of the liver, kidneys, pancreas, and heart revealed no drug-related lesions [1]. No significant hypoglycemic events were observed at therapeutic doses in all animal models, indicating that the drug has good safety [1,2].

---

Preclinical toxicology studies of Orforglipron indicate that the compound is generally well-tolerated. As a GLP-1 receptor agonist, potential side effects may include gastrointestinal symptoms such as nausea and vomiting, which are common with this class of compounds. Long-term safety studies would be required for clinical development. The compound is for research use only.

Because peptide GLP-1R agonists have an appetite-suppressing effect, which is part of their ability to improve overall metabolic control, this study administered LY3502970 orally to monkeys to investigate the compound's ability to suppress food intake. Food intake was measured within 90 minutes after treatment with either LY3502970 or exenatide. In this study, LY3502970 was administered orally 180 minutes before feeding, and exenatide was administered subcutaneously 30 minutes before feeding, consistent with the time to maximum concentration (Tmax) observed in monkey pharmacokinetic studies. Dosing was once daily for 5 consecutive days, followed by a 2-day recovery period. LY3502970 at doses of 0.05 and 0.1 mg/kg doses resulted in a dose-dependent reduction in food intake from day 1 to day 5 (Figure 5F), similar to the effects of exenatide at doses of 0.3 and 0.6 µg/kg (Figure 5G). The mean concentrations of LY3502970 and exenatide required to reduce food intake were 8.3 ± 0.8 nmol/L and 83.1 ± 4.5 pmol/L, respectively (mean ± standard error, n = 8). These results indicate that oral administration of LY3502970 can achieve a similar food intake reduction effect as the injectable GLP-1 receptor agonist exenatide. In summary, the preclinical pharmacodynamic profile of LY3502970 is similar to that of marketed peptide GLP-1 receptor agonists and has pharmacokinetic properties suitable for oral administration in humans. Therefore, LY3502970 is currently being evaluated in an early clinical trial for its potential as an antidiabetic drug (identifier, NCT04426474). [2]

For treatment regimen estimates, each dose of ozoglione resulted in a significant reduction in A1C. In the key secondary endpoint of body weight, both the 12 mg and 36 mg dose groups achieved statistically significant reductions.
Glycated hemoglobin (A1C) reduction: 1.2% (3 mg), 1.5% (12 mg), 1.5% (36 mg), 0.4% (placebo)
Percentage of weight loss: 4.5% (3 mg), 5.8% (12 mg), 7.6% (36 mg), 1.7% (placebo)
Weight loss: 4.2 kg (9.3 lb; 3 mg), 5.2 kg (11.5 lb; 12 mg), 7.2 kg (15.8 lb; 36 mg), 1.5 kg (3.4 lb; placebo)
In the ACHIEVE-1 study, the overall safety profile of ozoglerone was consistent with established GLP-1 inhibitors. The most frequently reported adverse events were gastrointestinal-related adverse events, which were generally mild to moderate. The most common adverse events in subjects treated with ofoglitazone (3 mg, 12 mg, and 36 mg) were diarrhea (19%, 21%, and 26%, respectively, compared to 9% in the placebo group), nausea (13%, 18%, and 16%, respectively, compared to 2% in the placebo group), dyspepsia (10%, 20%, and 15%, respectively, compared to 7% in the placebo group), constipation (8%, 17%, and 14%, respectively, compared to 4% in the placebo group), and vomiting (5%, 7%, and 14%, respectively, compared to 1% in the placebo group). The treatment discontinuation rates due to adverse events were 6% (3 mg), 4% (12 mg), and 8% (36 mg) in the ofoglitazone group, compared to 1% in the placebo group. No liver safety signals were observed. The results of the ACHIEVE-1 study will be presented at the 85th Scientific Session of the ADA and published in a peer-reviewed journal. Later this year, we will share more results from the ACHIEVE Phase III clinical trial program, as well as the results from the ATTAIN Phase III clinical trial program evaluating orforglipron for weight management. Eli Lilly expects to submit a marketing application for orforglipron for weight management to global regulatory agencies by the end of this year, and plans to submit a marketing application for the treatment of type 2 diabetes in 2026.
About Orforglipron
Orforglipron is an investigational once-daily oral small molecule (non-peptide) glucagon-like peptide-1 receptor agonist that can be taken at any time of day and is not restricted by food and water intake. ⁵Orforglipron was discovered by Chugai Pharmaceutical Co., Ltd., and licensed by Eli Lilly in 2018. Chugai Pharmaceutical and Eli Lilly jointly published preclinical pharmacological data for this molecule. Eli Lilly is conducting a Phase 3 clinical trial of ozoglione for the treatment of type 2 diabetes and for weight management in obese or overweight adults with at least one weight-related disorder. Currently, the drug is being investigated as a potential treatment for obese adults with obstructive sleep apnea and hypertension.
About ACHIEVE-1 and the ACHIEVE Clinical Trial Program
ACHIEVE-1 (NCT05971940) is a Phase 3, 40-week randomized, double-blind, placebo-controlled trial designed to compare the efficacy and safety of ozoglione 3 mg, 12 mg, and 36 mg monotherapy versus placebo in adult patients with type 2 diabetes whose blood glucose is not adequately controlled by diet and exercise alone. The trial randomized 559 participants in the United States, China, India, Japan, and Mexico to receive ozoglione 3 mg, 12 mg, or 36 mg or placebo in a 1:1:1:1 ratio. This study aimed to demonstrate that ofoglitazone (3 mg, 12 mg, 36 mg) was more effective than baseline in reducing glycated hemoglobin (HbA1c) after 40 weeks in patients with type 2 diabetes who had not previously taken any hypoglycemic agents or received insulin therapy for at least 90 days. Participants had HbA1c levels ≥7.0% to ≤9.5% and a body mass index (BMI) ≥23 kg/m². All participants in the ofoglitazone treatment group started the study with a once-daily dose of 1 mg, which was then gradually increased at four-week intervals until a final randomized maintenance dose was reached: 3 mg (increases by 1 mg each time), 12 mg (increases by 1 mg, 3 mg, and 6 mg, respectively), or 36 mg (increases by 1 mg, 3 mg, 6 mg, 12 mg, and 24 mg, respectively). Flexible dosing was not permitted.
The ACHIEVE Phase III global clinical development program for orforglipron has enrolled more than 6,000 patients with type 2 diabetes in five registration trials worldwide. The program began in 2023 and results are expected later this year and in 2026. https://investor.lilly.com/news-releases/news-release-details/lillys-oral-glp-1-orforglipron-demonstrated-statistically
