Which Weight Management Studies Evaluated the Effect of Orforglipron on Lipids? 

The effects of orforglipron on lipids in adults with obesity or overweight were evaluated in 2 randomized, double-blind, placebo-controlled trials, including 

  • ATTAIN-1 in adults with obesity or overweight with at least one weight-related comorbidity excluding type 2 diabetes (T2D), and
  • ATTAIN-2 in adults with obesity or overweight with T2D.1,2

ATTAIN-1 and ATTAIN-2 had a treatment duration of 72 weeks and compared an investigational orforglipron capsule formulation with placebo.1,2

This response presents efficacy data from the investigational orforglipron capsule formulation (1 mg, 3 mg, 6 mg, 12 mg, 24 mg, and 36 mg) shown as equivalent doses of once daily orforglipron tablets (0.8 mg, 2.5 mg, 5.5 mg, 9 mg, 14.5 mg, and 17.2 mg) approved in the United States.1-3

In both studies, all participants received lifestyle interventions, including guidance on diet and physical activity.1,2

What Were The Changes in Lipids in ATTAIN-1 in Adults With Obesity or Overweight With Weight-Related Comorbidities Excluding Type 2 Diabetes? 

In ATTAIN-1, key secondary endpoints related to lipids and adjusted for multiplicity included the percent change from baseline to week 72 in non-high-density lipoprotein (non-HDL) cholesterol and triglycerides for the pooled orforglipron doses.1

Additional endpoints not controlled for multiplicity included the percent change in

  • total cholesterol 
  • low-density lipoprotein (LDL) cholesterol
  • high-density lipoprotein (HDL) cholesterol, and
  • very low density lipoprotein (VLDL) cholesterol.1 

At week 72, for the treatment-regimen estimand, pooled orforglipron doses led to a

  • -6.7% change in non-HDL cholesterol compared with -1.9% with placebo (p<.001), and 
  • -14.8% change in triglycerides compared with -3.8% with placebo (p<.001, Efficacy Endpoints Related to Lipids in ATTAIN-1 (Treatment-Regimen Estimand)).1

Refer to Additional Secondary Efficacy Endpoints Related to Lipids in ATTAIN-1 (Treatment-Regimen Estimand) for changes in other lipids based on the treatment-regimen estimand in ATTAIN-1.

In ATTAIN-2, key secondary endpoints related to lipids and adjusted for multiplicity included the mean change from baseline to week 72 in non-HDL cholesterol and triglycerides for the pooled orforglipron doses.2

Additional secondary endpoints not controlled for multiplicity included the percent change in

  • total cholesterol 
  • LDL cholesterol
  • HDL cholesterol, and
  • VLDL cholesterol.2

At week 72, for the treatment-regimen estimand, pooled orforglipron doses led to a

  • -6.2% change in non-HDL cholesterol compared to -2.5% with placebo (p<.05), and 
  • -16.0% change in triglycerides compared to -4.2% with placebo (p<.001, Efficacy Endpoints Related to Lipids in ATTAIN-2 (Treatment-Regimen Estimand)).2

Refer to Efficacy Endpoints Related to Lipids in ATTAIN-2 (Treatment-Regimen Estimand) for changes in other lipids based on the treatment-regimen estimand in ATTAIN-2.

Notes: Treatment-regimen estimand represents the estimated average treatment effect regardless of treatment discontinuation of study intervention or initiation of prohibited weight management treatments.

aData are presented as model-based estimates for changes from baseline to week 72, along with ETD (95% CI) between the OFG groups and placebo based on ANCOVA analysis (treatment-regimen estimand). The CIs have not been adjusted for multiplicity and should not be used for hypothesis testing. For the percentage of participants with efficacy thresholds at week 72, data are presented as model-based estimate from logistic regression. 

bChange from baseline to week 72 in non-HDL cholesterol, and triglyceride for orforglipron individual doses of 5.5 mg, 9 mg, or 17.2 mg vs placebo were not key secondary endpoints in ATTAIN-2 and thus not controlled for multiplicity. P values were not included.

Figure 2 description: In ATTAIN-2, mean percent change from baseline to week 72 in triglycerides was -16.0% with orforglipron pooled doses compared to -4.2% with placebo (p<.001). The mean percent change from baseline to week 72 in non-HDL cholesterol was -6.2% with orforglipron pooled doses compared to -2.5% with placebo (p<.05). Orforglipron pooled doses led to a 6.4% change in HDL cholesterol in comparison with 1.0% with placebo. The mean percent change in LDL cholesterol was -1.6% with orforglipron pooled doses in comparison with -2.7% with placebo. Orforglipron pooled doses led to a -14.3% change in VLDL cholesterol in comparison with -4.5% with placebo. The mean percent change from baseline to week 72 in total cholesterol was -2.5% with orforglipron pooled doses compared to -1.8% with placebo.
