About this study

Official title: A Phase 1, Open-label Study to Assess Copper Balance in Healthy Participants Following Administration of ALXN1840

The study will assess the change from baseline in mean daily copper balance in healthy participants with repeat-dose administrations of ALXN1840 over 2 weeks.

Read the detailed description

This study will also characterize the steady state absorption, distribution, metabolism, and excretion (mass balance) of total molybdenum, which is a surrogate measure of ALXN1840 disposition.

Safety will be monitored throughout the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Baseline, Days 4 to 15

Secondary outcomes (11)
  1. Mean Daily Copper Balance Over Two Weeks of Repeated ALXN1840 Dosing

    Copper balance was defined by 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.

    Measured: Day 4 through Day 15

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

    Molybdenum mass balance was defined as the difference in molybdenum input and molybdenum output. A negative molybdenum balance indicated greater molybdenum output than molybdenum intake. Molybdenum input was defined as the sum of all molybdenum input as measured in all food and fluids over the specified period. Molybdenum output was defined as the sum of all molybdenum 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.

    Measured: Baseline, Days 12 to 15

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

    Molybdenum mass balance was defined as the difference in molybdenum input and molybdenum output. A negative molybdenum balance indicated greater molybdenum output than molybdenum intake. Molybdenum input was defined as the sum of all molybdenum input as measured in all food and fluids over the specified period. Molybdenum output was defined as the sum of all molybdenum 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. Molybdenum excretion for the Day 4 through Day 15 period included data averaged from Day 4 through Day 15.

    Measured: Baseline, Days 4 to 15

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

    Molybdenum mass balance was defined as the difference in molybdenum input and molybdenum output. A negative molybdenum balance indicated greater molybdenum output than molybdenum intake. Molybdenum input was defined as the sum of all molybdenum input as measured in all food and fluids over the specified period. Molybdenum output was defined as the sum of all molybdenum output as measured in urine and feces over the specified collection period.

    Measured: Day 1 through Day 15

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

    Copper balance for the Day 4 through Day 15 period included data averaged from Day 4 through Day 15.

    Measured: Days 4 to 15

  6. Copper Quantified in Food, Drink, Feces, and Urine From Day 1 Through Day 30

    Copper balance for the Day 1 through Day 30 period included data averaged from Day 1 through Day 30.

    Measured: Day 1 through Day 30

  7. Plasma Total Copper Concentration and Labile Bound Copper (LBC) Concentration

    Measured: Day 15 (predose and 24 hours postdose)

  8. Molybdenum Quantified in ALXN1840 Doses Given and in Food, Drink, Feces, And Urine

    Molybdenum balance for the Day 1 through Day 30 period included data averaged from Day 1 through Day 30.

    Measured: Day 1 through Day 30

  9. Maximum Observed Plasma Concentration (Cmax) of Total Molybdenum and Plasma Ultrafiltrate (PUF) Molybdenum

    Measured: Predose (within 1 hour prior to dosing) through 24 hours postdose on Day 1 and Day 15

  10. Area Under the Plasma Concentration Versus Time Curve Over the Dosing Interval (AUCtau) of Total Molybdenum and PUF Molybdenum

    Measured: Predose (within 1 hour prior to dosing) through 24 hours postdose on Day 1 and Day 15

  11. Observed Concentration at the End of the Dosing Interval (Ctau) of Total Molybdenum and PUF Molybdenum

    Measured: Predose (within 1 hour prior to dosing) through 24 hours postdose on Day 1 and Day 15

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALXN1840 in people with Healthy, run by Alexion Pharmaceuticals, Inc. at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Mean Daily Copper Balance Over 2 Weeks of Repeated Daily ALXN1840 Dosing (Over Days 4 to 15) (time frame: Baseline, Days 4 to 15). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Aug 2024.
