Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Males and females at least 18 years of age, with body mass not less than 50 kg.
  • Female subjects had to be post-menopausal, surgically sterilized or using a reliable method of contraception.
  • Subjects suffering from a chronic illness, other than hepatic impairment, had to have a stable condition, regarded by the investigator as unlikely to influence the outcome of the study.
  • Renal failure, the extent of which, as measured by the creatinine clearance, resulted in recruitment to one of five renal function groups.
  • Medical records indicating a stable serum creatinine (variation of not more than 30%), for at least 3 months prior to the screening visit (Groups 2 to 4 only), as determined by the clinical investigator. The sérum creatinine had to be stable to allow for an accurate determination of the creatinine clearance and therefore allowed for correct allocation to one of the renal function groups. Subjects who were recruited into Group 1 had normal renal function.

Who cannot join

  • The receipt of any investigational drug within 30 days prior to this study.
  • Clinically significant abnormal findings (as judged by the investigator) for the following parameters, except those consistent with findings in renal failure: haematology, biochemistry, clotting profile, urinalysis, vital signs or ECG screening tests.
  • A history or laboratory evidence of hepatic impairment and/or disease. Owing to the metabolic pathway of BIA 2-093, any degree of hepatic impairment would have had a confounding effect on the PK analysis.
  • Positive test for HIV-1 or HIV-2 Antibodies, Hepatitis B surface antigen and Hepatitis C Antibodies.
  • HIV positive patients, and patients with Hepatitis B and C, generally have a below average, and in some cases a markedly decreased, level of health owing to the nature of the respective infections and the natural course of the diseases, both of which are often complicated by an array of opportunistic illnesses. Their ill health would have been further worsened by the fact that the patients are invarious degrees of renal failure, which has its own, often debilitating, complications. If patients with HIV or Hepatitis B or C were included in the study, this could have led to statistical confusion when assessing the safety and tolerability parameters. This is because events reported by the patients, which may be a part of the spectrum of complaints in HIV positive patients and Hepatitis B and C patients, would have confounded the safety and tolerability analysis. Furthermore, Hepatitis B and C, which may cause an element of hepatic impairment, would have confounded the PK analysis due to the metabolic pathway of BIA 2-093. In addition, by administering the study medication to these subjects, any adverse events that might have occurred would have added to the discomfort of the patient.
  • A history of any illness that, in the opinion of the Investigator and/or Sponsor, might have confounded the results.

About this study

Official title: An Open-label, Single-dose, Single-centre Study, Investigating the Pharmacokinetics of BIA 2-093 in Subjects With Various Degrees of Renal Impairment

Open-label, single-dose (BIA 2-093 800 mg tablet), single-centre study in five groups of subjects with various degrees of renal function based on creatinine clearance

Read the detailed description

This was an open-label, single-dose (BIA 2-093 800 mg tablet), single-centre study in five groups of subjects with various degrees of renal function based on creatinine clearance (stages of renal function according to the Food and Drug Administration and the European Agency for the Evaluation of Medicinal Products Guidelines) for the evaluation of pharmacokinetics in patients with impaired renal function.

The trial commenced with Groups 1 and 2. An interim safety evaluation was conducted and, as there were no safety concerns, the trial continued with Groups 3 and 4. After another interim safety evaluation with the data from Groups 3 and 4, the trial commenced with Group 5.

What is being measured

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

  1. Cmax - Peak Plasma Concentration

    BIA 2-194; BIA 2-195; Oxcarbazepine are BIA 2-093 metabolites

    Measured: pre-dose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 5, 7, 9, 12, 24, 48, 72 and 96 hours post-dose.

  2. AUC(0-12h) - AUC From Time Zero to 12h

    BIA 2-194; BIA 2-195; Oxcarbazepine are BIA 2-093 metabolites

    AUC - area under the plasma concentration versus time curve

    Measured: pre-dose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 5, 7, 9, 12, 24, 48, 72 and 96 hours post-dose.

Secondary outcomes (1)
  1. Tmax (hr) - Time at Which Cmax Occurred

    BIA 2-194; BIA 2-195; Oxcarbazepine are BIA 2-093 metabolites

    Cmax - maximum observed plasma drug concentration

    Measured: pre-dose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 5, 7, 9, 12, 24, 48, 72 and 96 hours post-dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BIA 2-093 in people with Epilepsy, run by Bial - Portela C S.A. at 1 site in South Africa.

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 6 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 31 Dec 2014. 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 South Africa. 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 31 Dec 2014). 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?

Cmax - Peak Plasma Concentration (time frame: pre-dose and 1, 2, 2.25, 2.5, 2.75, 3, 3.25, 3.5, 3.75, 4, 5, 7, 9, 12, 24, 48, 72 and 96 hours post-dose.). 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 31 Dec 2014.
