About this study

Official title: A Single and Multiple Dose, Open-Label Study of the Pharmacokinetics, Safety, and Tolerability of Dexpramipexole (BIIB050) in Healthy Japanese and Caucasian Subjects

This is a single and multiple dose, open-label study to evaluate the pharmacokinetics (PK), safety, and tolerability of dexpramipexole administered orally to adult Japanese and Caucasian healthy subjects.

Read the detailed description

The study is designed to evaluate the influence of ethnic factors on dexpramipexole safety, tolerability, and PK. Subjects will be admitted to the clinical unit on Day -1 (the day prior to first dosing) and will remain in the clinical unit under observation until discharge. All subjects will have a final follow up visit. Whilst resident in the clinic, subjects will receive 4 treatments: The first 3 treatments comprise Part A of the study and the final treatment group comprises Part B.

Part A:

Treatment 1: Dose 1 (reduced) of dexpramipexole; a single dose Treatment 2: Dose 2 (standard) dexpramipexole; a single dose Treatment 3: Dose 3 (standard) dexpramipexole; 5 doses administered at 12 hour intervals Part B: Dose 4 (standard) dexpramipexole; 5 doses administered at 12 hour intervals There will be a minimum washout of 3 days between treatments.

For all subjects, prior to proceeding to the next treatment group, safety and tolerability data will be reviewed.

Caucasian subjects will be matched individually (on a 1:1 basis) to Japanese subjects with respect to gender and age and if possible BMI.

What is being measured

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

  1. Cmax of dexpramipexole

    Measured: pre-dose and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing on Days 1 and 5 in Treatments 1 and 2, and after the fifth dose on Day 11 in Treatment 3 for Parts A & B.

  2. AUC of dexpramipexole

    Measured: pre-dose and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing on Days 1 and 5 in Treatments 1 and 2, and after the fifth dose on Day 11 in Treatment 3 for Parts A & B.

Secondary outcomes (4)
  1. Changes in clinical laboratory tests

    Measured: pre-dose to 72 hrs post-dose in each dose group and again at follow-up (14 hrs post last dose)

  2. ECG changes

    Measured: pre-dose to 72 hrs post-dose in each dose group and again at follow-up (14 hrs post last dose)

  3. Vital Sign changes

    Measured: pre-dose to 72 hrs post-dose in each dose group and again at follow-up (14 hrs post last dose)

  4. Adverse Event monitoring

    Measured: pre-dose to 72 hrs post-dose in each dose group and again at follow-up (14 hrs post last dose)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Single dose reduced, Single dose standard and Multiple Dose in people with Amyotrophic Lateral Sclerosis, run by Knopp Biosciences 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 7 inclusion and 5 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 22 Jun 2021. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Cmax of dexpramipexole (time frame: pre-dose and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing on Days 1 and 5 in Treatments 1 and 2, and after the fifth dose on Day 11 in Treatment 3 for Parts A & B.). The study lists 2 primary outcomes in all. 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 22 Jun 2021.
