Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Mean Daily Copper Balance Over 2 Weeks of Repeated Daily ALXN1840 Dosing (Over Days 4 to 15)

    Copper balance was defined as the difference in copper input and copper output. A negative copper balance indicated greater copper output than copper intake. Copper input was defined as the sum of all copper input as measured in all food and fluids over the specified period. Copper output was defined as the sum of all copper output as measured in urine and feces over the specified collection period. Baseline was defined as the average of the nonmissing values on or before first study drug administration from Day -4 to Day -1.

    Baseline, Days 4 to 15

Secondary Outcomes (11)

  • Mean Daily Copper Balance Over Two Weeks of Repeated ALXN1840 Dosing

    Day 4 through Day 15

  • Change From Baseline in Mean Daily Molybdenum Balance at Steady State (Over Days 12 to 15)

    Baseline, Days 12 to 15

  • Change From Baseline in Total Molybdenum Excretion in Urine and Feces Averaged Over 2 Weeks of Dosing (Days 4 to 15)

    Baseline, Days 4 to 15

  • Mean Daily Molybdenum Balance Throughout the ALXN1840 Treatment Period (Day 1 Through Day 15)

    Day 1 through Day 15

  • Copper Quantified in Food, Drink, Feces, and Urine Averaged Over 2 Weeks of Dosing

    Days 4 to 15

  • +6 more secondary outcomes
