Summary:

      This study is open to adults, aged 18 to 75 years, with overweight or obesity. People with
      body mass index (BMI) of 27 or higher to join the study. People who have diabetes cannot
      participate. The purpose of this study is to find out whether a medicine called BI 456906
      helps people lose weight.

      Participants are put into 5 groups by chance. 4 groups get different doses of BI 456906. The
      fifth group gets placebo. Participants get BI 456906 or placebo as injections under the skin
      once a week. Placebo injections look like BI 456906 injections but do not contain any
      medicine.

      Participants are in the study for about a year. During this time, there are about 20
      in-person visits to the study site. At the study site visits, doctors measure participants'
      body weight. Results are compared between the BI 456906 groups and the placebo group. The
      doctors also regularly check the general health of the participants.
