Weight Maintenance and Additional Weight Loss with Liraglutide after Low-calorie Dietinduced Weight Loss: the SCALE™ Maintenance Randomized Study Thomas Wadden, Priscilla Hollander, Samuel Klein, Kevin Niswender, Vincent Woo, Paula M. Hale, and Louis Aronne, on behalf of the NN8022-1923 Investigators Non-thyroid related neoplasms reported during the trial Three non-thyroid malignant neoplasms (reported as AEs) occurred in participants treated with liraglutide 3.0 mg; two cases of breast cancer (ductal carcinoma in situ and bilateral breast cancer), and one case of ovarian cancer. Benign neoplasms in 6 liraglutide-treated participants included benign breast neoplasm, fibroma, lipoma, papilloma, prolactinoma and a uterine leiomyoma. Four participants in the placebo-treated group exhibited neoplasms. Two malignancies were reported; one basal cell carcinoma and one case of metastases to the lung. Two benign neoplasms were reported; one case of pseudolymphoma that had been a recurrence, and one report of a benign skin papilloma. 1 Supplementary Table 1 Complete list of inclusion and exclusion criteria Inclusion criteria 1.

Estimated treatment differences are from an analysis of covariance, and odds ratios are from a logistic regression analysis. The per-protocol analysis set included all participants from the full analysis set who did not significantly violate inclusion, exclusion or randomization criteria, who had a valid assessment at week 56, where week 56 was at least 52 weeks (365 days) after first drug date, but who were allowed to be off drug for a total of 4 weeks during the trial, but at most 2 consecutive weeks. No imputation was performed on the data. Body weight was measured in the fasting state. The repeated measures analysis (linear mixed-effect model) was done using the full analysis set with no imputation. Body weight was measured in the fasting state. *This sensitivity analysis also included observations off drug, and was performed using the last observation carried forward. 5 Supplementary Table 3 Additional measures of body weight maintenance Change from randomization to week 56 Proportion with ≥5% weight Estimated odds ratios for liraglutide vs. placebo (95% CI), P value Liraglutide 3.0 mg Placebo n=207 n=208 1.9% 17.5% 0.09 (0.03, 0.26), P<0.0001 0.0% 2.9% 0.0 (0.0, non-estimable), P=1.0 93.2% 70.9% 5.9 (3.1, 11.0), P<0.0001 87.4% 54.4% 6.0 (3.7, 9.9), P<0.0001 regain Proportion with ≥10% weight regain Proportion maintaining >50% run-in weight loss Proportion maintaining >75% run-in weight loss Changes from randomization to week 56 are observed means.
