Treatment Sequence 1: ABC
Participants received each treatment on 1 occasion: Period 1 (Treatment A): ALXN1840 60 milligrams (mg) (2 x 30 mg enteric-coated \[EC\] tablets) at Hour 0 on Day 1 following an overnight fast.

PRIMARY outcome

Timeframe: Day 1 through 14 days following final dose (up to Day 43)

Population: All enrolled participants who received at least 1 dose of study drug.

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 an AE that started or worsened at the time of or after study drug administration. 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.
