Description of intervention(s) / exposure
Treatment: Drugs - ALXN1840
Treatment: Drugs - SoC Therapy

Experimental: ALXN1840 - ALXN1840 was administered orally for 48 weeks at doses ranging from 15 milligrams (mg) every other day (QOD) up to a titrated dose of 60 mg daily.

Participants who completed the Primary Evaluation Period had the option to participate in the up to 60-month Extension Period.

Active comparator: Standard of Care (SoC) Medication - SoC medication was administered for 48 weeks. Participants who completed the Primary Evaluation Period had the option to participate in the up to 60-month Extension Period.


Treatment: Drugs: ALXN1840
ALXN1840 administered orally in 15 mg tablets

Treatment: Drugs: SoC Therapy
Depending on the site/region, participants randomized to receive SoC treatment will receive trientine, penicillamine, Zinc, or a combination of these medicines, administered according to standard regimens.
