a study of jnj-64565111 after single subcutaneous administration at different injection sites in otherwise healthy overweight/obese adult participants and a study of jnj-6456511 in otherwise healthy obese adult participants after multiple dose

Conditions: Obesity

Summary: the purpose of this study is to compare the relative bioavailability of jnj-64565111 between subcutaneous (sc) administrations in the upper arm versus the abdomen, and between sc administrations in the thigh versus the abdomen in otherwise healthy overweight/obese participants (part a) and to assess the gastrointestinal tolerability of jnj-64565111 following a dose titration in otherwise healthy obese participants at 6 weeks (part b).
