  1. 01HumanRandomized controlled trialEfficacy outcome

    In adults with overweight or obesity and no known major psychopathology, semaglutide 2.4 mg lowered PHQ-9 scores more than placebo at week 68 (estimated difference -0.56).

    In plain wordsIn adults with overweight or obesity, semaglutide lowered depression symptom scores slightly more than placebo; the authors did not call the change clinically meaningful.

    Summary
    PHQ-9 scores at week 68 were 2.0 (2.9) and 2.4 (3.3), respectively; the estimated treatment difference (95% CI) between groups was -0.56 (-0.81 to -0.32) (P < .001).

    This post hoc analysis of pooled data from the randomized, double-blind, placebo-controlled, multicenter phase 3a STEP 1, 2, and 3 trials (68 weeks; 2018-2020) and phase 3b STEP 5 trial (104 weeks; 2018-2021) included adults with overweight or obesity; STEP 2 participants also had type 2 diabetes.
  2. 02HumanRandomized controlled trialSafety outcome

    In adults with overweight or obesity, participants on semaglutide 2.4 mg were less likely than those on placebo to shift to a more severe PHQ-9 depression category by week 68 (odds ratio 0.63).

    Summary
    Participants treated with semaglutide vs placebo were less likely to shift (from baseline to week 68) to a more severe category of PHQ-9 depression (odds ratio, 0.63; 95% CI, 0.50-0.79; P < .001).
