Treatment Sequence A-B
Treatment A: Participants received a single oral dose of 1 × 150 milligrams (mg) bupropion hydrochloride (HCl) salt tablet in a fasted state on Day 1 of treatment period 1. Treatment B: Participants received a single oral dose of 1 × 150 mg bupropion HCl salt tablet coadministered with 4 × 15 mg enteric coated (EC) tablets of ALXN1840 in a fasted state on Day 1 of treatment period 2. There was a washout period of 14 days between the 2 treatment periods.
Treatment Sequence B-A
Treatment B: Participants received a single oral dose of 1 × 150 mg bupropion HCl salt tablet coadministered with 4 × 15 mg EC tablets of ALXN1840 in a fasted state on Day 1 of treatment period 1. Treatment A: Participants received a single oral dose of 1 × 150 mg bupropion HCl salt tablet in a fasted state on Day 1 of treatment period 2.

Population: Safety set included all participants who received at least 1 dose of study intervention.

An adverse event (AE) was defined as any untoward medical occurrence in a participant administered with the study drug and which did not necessarily have a causal relationship with the study drug. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not related to study drug. A TEAE was defined as any AE that began or worsened on or after the first dose of treatment until the end of study (EOS) or early termination (ET). An AE that occurred during the washout period between drugs was considered treatment emergent to the last drug given. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
