Orforglipron-Obesity

This information is provided in response to your request. Resources may contain information about doses, uses, formulations and populations different from product labeling.

In ATTAIN-1, how did orforglipron compare with placebo in adults with obesity or overweight with weight-related comorbidities?

In ATTAIN-1, orforglipron reduced body weight by 7.5% to 11.2% at 72 weeks, compared with 2.1% with placebo (treatment-regimen estimand). The safety and tolerability of orforglipron were consistent with injectable GLP-1 RAs.

ATTAIN-1 Overview 

ATTAIN-1 was a phase 3, 72-week, double-blind, randomized, placebo-controlled trial comparing the efficacy and safety of orforglipron 6 mg, 12 mg, and 36 mg as monotherapy to placebo as an adjunct to healthy diet and physical activity in adults with obesity without diabetes mellitus.1

Back to Content Overview .

Study Design in ATTAIN-1 

The ATTAIN-1 trial randomized 3127 participants across the United States (including Puerto Rico), Brazil, China, India, Japan, Republic of Korea, Slovakia, Spain, and Taiwan in a 3:3:3:4 ratio to receive either 

  • orforglipron 6 mg
  • orforglipron 12 mg 
  • orforglipron 36 mg, or 
  • placebo.1

During the study, orforglipron was administered daily by oral capsule without food and water restrictions.1

ATTAIN-1 Study Design Overview presents an overview of the study design, including the different treatment arms and dose escalation strategy for orforglipron.

ATTAIN-1 Study Design Overview1-3

Figure 1 description: ATTAIN-1 was a phase 3, 72-week, double-blind, placebo-controlled trial that randomized 3127 adults with obesity or overweight with at least one weight-related comorbidity in a 3:3:3:4 ratio to receive orforglipron (6 mg, 12 mg, or 36 mg) or placebo once daily. Orforglipron-treated participants followed a dose escalation regimen (starting at 1 mg, followed by 3 mg, 6 mg, 12 mg, 24 mg, and 36 mg) every 4 weeks until the assigned dose was reached. Dose reduction was allowed if  gastrointestinal symptoms persisted despite mitigations. All participants received personalized counselling throughout the study, focused on a healthy, balanced diet along with physical activity.

Key Primary and Secondary Endpoints in ATTAIN-1 

The primary objective in ATTAIN-1 was to demonstrate that orforglipron (6 mg, 12 mg, 36 mg) is superior to placebo in percent change in body weight from baseline to week 72.1

Key multiplicity-adjusted secondary endpoints measured at week 72 included the 

  • percent of participants with body weight reduction ≥5%, ≥10%, ≥15%, and ≥20%, and 
  • change from baseline in waist circumference, systolic blood pressure (SBP), non-high-density lipoprotein (non-HDL) cholesterol, and triglycerides.1

A graphical testing procedure for multiple comparisons was used for testing the primary and multiplicity-adjusted secondary end points to control for the overall family-wise type I error rate at 0.05.1

Back to Content Overview .

Baseline Demographics and Clinical Characteristics of Participants in ATTAIN-1 

In the ATTAIN-1 study, baseline demographics and clinical characteristics of participants were consistent across all treatment groups. At baseline, participants had a mean

  • age of 45 years 
  • body weight of 103.2 kg, and 
  • body mass index (BMI) of 37.0 kg/m2.1

In the overall study population, 64.2% of participants were female.1

At baseline, the mean glycated hemoglobin (HbA1c) was 5.6% and 36.0% of participants had prediabetes.1

More information on baseline demographics and clinical characteristics in the ATTAIN-1 study can be found in the Appendix .

Back to Content Overview .

Discontinuation

A total of 2662 (85.1%) participants completed the ATTAIN-1 trial, and 2344 (75.0%) participants continued to receive study treatment throughout the 72-week treatment period.1

The proportion of participants who discontinued treatment for any reason was between

  • 21.9% to 24.4% in the orforglipron groups, and
  • 29.9% in the placebo group.1

The most common reasons were participant decision to withdraw and adverse events (AEs).1

Efficacy Results From ATTAIN-1 

Efficacy Estimand and Treatment Regimen Estimand

Two statistical estimands, efficacy or treatment-regimen, were used to evaluate efficacy data in ATTAIN-1. Briefly, the 

  • efficacy estimand represents treatment effect as if all randomized participants remained on study intervention (with possible dose interruptions and modifications) for 72 weeks without initiating prohibited weight management treatments, and 
  • treatment-regimen estimand represents the estimated average treatment effect regardless of treatment discontinuation of study intervention or initiation of prohibited weight management treatments.1

The treatment-regimen estimand was the primary estimand, with the efficacy estimand considered supportive. There was no adjustment for multiple comparisons between estimands, nor for any other analyses beyond the primary and key secondary objectives.1

Back to Content Overview .

Primary and Secondary Endpoint Results From ATTAIN-1 

In ATTAIN-1, treatment with orforglipron met the primary endpoint of superior body weight reduction compared with placebo.1

At week 72, for the treatment-regimen estimand, mean percent change from baseline in body weight was 

  • -7.5% with orforglipron 6 mg
  • -8.4% with orforglipron 12 mg 
  • -11.2% with orforglipron 36 mg, and 
  • -2.1% with placebo (p<.001 for all orforglipron doses vs placebo;  Treatment-Regimen and Efficacy Estimand for Efficacy Endpoints in ATTAIN-1).1

Change in body weight over time in ATTAIN-1 is presented in Change From Baseline in Body Weight Over Time in ATTAIN-1.

Change From Baseline in Body Weight Over Time in ATTAIN-11,3

Figure 2 description: In ATTAIN-1, change from baseline in body weight at week 72 was -7.8%, -9.3%, and -12.4% with orforglipron 6 mg, 12 mg, and 36 mg, respectively, and -0.9% with placebo. 

Notes: Data are presented as model-based estimates (95% CI), along with ETD (95% CI) between orforglipron groups and placebo based on MMRM analysis (efficacy estimand). 

Abbreviations: ETD = estimated treatment difference; MMRM = mixed model for repeated measures; OFG = orforglipron; PBO = placebo. 

For the treatment-regimen estimand, significantly more participants treated with orforglipron had body weight reduction ≥5%, ≥10%, ≥15%, and 20% at week 72 when compared with placebo (p<.001 for all orforglipron doses vs placebo) as presented in  Treatment-Regimen and Efficacy Estimand for Efficacy Endpoints in ATTAIN-1.1

Additionally, as described in  Treatment-Regimen and Efficacy Estimand for Secondary Cardiometabolic Risk Factor Efficacy Endpoints in ATTAIN-1, for the treatment-regimen estimand at week 72, significant improvements were observed for the key secondary cardiometabolic risk factor endpoints, which included 

  • waist circumference (p<.001 for all orforglipron doses vs placebo), and 
  • SBP, non-HDL cholesterol, and triglycerides (p<.001 for the pooled orforglipron group vs placebo for each endpoint).1

Refer to  Treatment-Regimen and Efficacy Estimand for Efficacy Endpoints in ATTAIN-1 and  Treatment-Regimen and Efficacy Estimand for Secondary Cardiometabolic Risk Factor Efficacy Endpoints in ATTAIN-1 for additional information on the primary and key secondary endpoint efficacy estimand results at week 72.

Safety Results From ATTAIN-1 

The overall safety profile of orforglipron in ATTAIN-1 was consistent with the established GLP-1 receptor agonist class.1

The most commonly reported AEs were gastrointestinal-related. These events were generally mild to moderate in severity and started mainly during dose escalation in orforglipron-treated participants.1

The proportion of participants that discontinued due to gastrointestinal AEs were

  • 3.5% to 7.0% of orforglipron-treated participants, and

  • 0.4% of placebo participants.1

An overview of AEs and AEs that occurred in ≥5% of participants are presented in Overview of Adverse Events and  Adverse Events Occurring in ≥5% of Participants in the ATTAIN-1 Study, respectively.

Five cases of adjudication-confirmed mild pancreatitis were reported in participants receiving orforglipron (1 participant in the orforglipron 6 mg group and 2 participants each from the 12 mg and 36 mg orforglipron dose groups) with none reporting complications.1

A total of 8 participants (7 orforglipron-treated participants and 1 placebo-treated participant) experienced transaminase elevations ≥10x upper limit of normal (ULN). For all 7 orforglipron participants, alternative causes were identified.1

Two participants in the orforglipron groups had elevated total bilirubin >2x ULN with ALT elevation >3x ULN. Both cases had alternative causes and were not associated with drug-induced liver injury.1

There were no cases of medullary thyroid cancer.1

At week 72, mean pulse rate increased by 

  • 4.3 to 5.3 beats per minute across orforglipron doses, and 
  • 0.8 beats per minute with placebo.1
