The main goal of this trial is to learn how a new tablet formulation of Lu AG06466 behaves in the body. Researchers will compare the new tablet formulation to the capsule formulation that is currently being tested in other clinical trials. They will measure the levels of the drug in the bloodstream for up to 3 days after participants take either the tablet or the capsule formulation. They will also look at whether the tablet formulation behaves differently when it is taken with and without food.

This study will consist of 6 sequences with 4 periods (3 days/period) in each sequence. The first 3 periods will be randomized. Each Lu AG06466 dose administration will be separated by a washout period of at least 72 hours.

Inclusion Criteria:

• The participant has a body mass index (BMI) ≥18.5 and ≤30 kg/m^2 at the Screening Visit and at the Baseline Visit.
• The participant is, in the opinion of the investigator, generally healthy based on medical history; a physical examination; vital signs; an electrocardiogram (ECG); and the results of the clinical chemistry, hematology, urinalysis, serology, and other laboratory tests at the Screening Visit and/or the Baseline Visit.

Exclusion Criteria:

• The participant has a personal history of a clinically significant psychiatric disorder (including severe affective disorder, severe anxiety disorder, psychotic tendencies, and drug-induced psychoses).
