  • Adult, Older adult

Who may be able to join

  • Adult males/females aged 18 to 75 years inclusive and between 19 and 36 kg/m2 inclusive BMI.
  • Subjects with renal impairment must have stable renal disease (i.e., no change in disease status within the 28 days prior to dosing) as determined by the Investigator with laboratory and clinical findings that support the diagnosis of renal impairment.
  • Subjects with renal impairment (excluding ESRD subjects), must have 2 separate estimates of creatinine clearance that are within 25% of each other, obtained >5 days apart, but not >6 months apart
  • Subjects must have a GFR (estimated GFR; as defined by estimation of creatinine clearance using the MDRD formula) of ≥80 (healthy volunteers), between 50 and 79 (mild renal impairment), between 30 and 49 (moderate renal impairment), or <30 (severe renal impairment), or must require dialysis ≤3 times a week (ESRD).

Who cannot join

  • Healthy volunteers who have received prescription medication within the 14 days prior to dosing (except for birth control).

About this study

Official title: A Multicenter, Open-Label, Single-dose, Pharmacokinetic and Safety Study of Dexpramipexole (BIIB050) in Healthy Subjects and Subjects With Renal Impairment

This is a multicenter, open-label, single-dose, PK and safety study in subjects with various stages of renal impairment.

Read the detailed description

Dexpramipexole (BIIB050, KNS-760704; (6R)-4,5,6,7-tetrahydro-N6-propyl-2,6-benzothiazolediamine dihydrochloride monohydrate) is a synthetic amino-benzothiazole. Data from multiple in vitro and in vivo assays have suggested that dexpramipexole is neuroprotective. It is being investigated for the treatment ALS.

As dexpramipexole is principally eliminated from the body by the kidneys a single oral dose of dexpramipexole will be administered to subjects with various stages of renal impariment comprising the following categories: mild, moderate, severe and ESRD subjects. Healthy volunteers will be matched to each catergory of renal impaired subjects.

Being tested
Dexpramipexole (dose 1), Dexpramipexole (dose 2)
Medical subject headings
Amyotrophic Lateral Sclerosis, Renal Insufficiency

What is being measured

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

  1. AUC after single dose of dexpramipexole

    Measured: pre dose and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing in all subjects, and in addition at 96, 120, and 144 hours after dosing in subjects with severe renal impairment and ESRD.

  2. Cmax after single dose of dexpramipexole

    Measured: pre dose and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing in all subjects, and in addition at 96, 120, and 144 hours after dosing in subjects with severe renal impairment and ESRD.

Secondary outcomes (4)
  1. Mointoring of Clinical Laboratory tests

  2. ECG Monitoring

    Measured: pre-144 hrs post dose

  3. Vital Sign monitoring

    Measured: pre-144 hrs post dose

  4. AE monitoring

    Measured: pre-144 hrs post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dexpramipexole (dose 1) and Dexpramipexole (dose 2) in people with Amyotrophic Lateral Sclerosis and Renal Insufficiency, run by Knopp Biosciences at 2 sites in United States.

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 5 inclusion and 2 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 25 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

AUC after single dose of dexpramipexole (time frame: pre dose and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, and 72 hours after dosing in all subjects, and in addition at 96, 120, and 144 hours after dosing in subjects with severe renal impairment and ESRD.). 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 25 Nov 2014.
