About this study

Official title: Pharmacokinetic-pharmacodynamic Interaction Between Three Different Single Doses of BIA 3-202 and a Single-dose of Controlled-release 100/25 mg Levodopa/Benserazide (Madopar® HBS 125): a Double-blind, Randomised, Four-way Crossover, Placebo-controlled Study in Healthy Volunteers

The purpose of this study is to determine the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 100 mg/benserazide 25 mg (Madopar® HBS 125).

STUDY DESIGN AND METHODOLOGY:

Single centre, double-blind, randomised, placebo-controlled, 4-way crossover study with 4 single-dose treatment periods. The washout period between doses was 5 days or more.

Screening: Subjects were screened for eligibility within 28 and 7 days before first admission. The screening consisted of: medical history; physical examination, vital signs; complete neurological examination; 12-lead ECG; haematology, coagulation, plasma biochemistry and urinalysis tests; HIV, hepatitis B and hepatitis C serology; drugs of abuse and alcohol screen; urine pregnancy test in women of childbearing potential; and review of the selection criteria.

Treatment periods: In each treatment period, eligible subjects were admitted to the UFH on the day prior to receiving the study medication for: vital signs; medical history and physical examination updates; 12-lead ECG; haematology and plasma biochemistry; drugs of abuse and alcohol screen; and urine pregnancy test in women of childbearing potential. On first admission, subjects had a review of the selection criteria and were randomly assigned to one of the treatment sequences. On the morning of the dosing day, subjects received a dose of nebicapone/placebo concomitantly with a dose of Madopar® HBS 125 in fasting conditions (at least 8 hours) and remained in the UFH until at least 24 h post-dose; then, they left and returned for the next period or the follow-up visit. At given time-points between pre-dose and discharge, subjects were submitted to vital signs recording, brief neurological examination, 12-lead ECG, and blood sampling for plasma drug determination and erythrocyte S-COMT activity assay. At discharge, vital signs and ECG were recorded, and haematology and plasma biochemistry tests were performed. Blood samples (7 mL) for the determination of plasma concentration of levodopa, 3-O-methyldopa (3-OMD) and nebicapone, and for the assay of the erythrocyte S-COMT activity were taken at the following times: pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 h post-dose.

Follow-up: A follow-up visit occurred approximately 7-10 days after discharge of last treatment period or early discontinuation for: medical history and physical examination updates; vital signs; 12-lead ECG; haematology, plasma biochemistry and urinalysis tests; and pregnancy test in women of childbearing potential.

  3. Area under the plasma concentration-time curve (AUC) from time zero to the last sampling time at which concentrations were at or above the limit of quantification (AUC0-t)

    Mean AUC0-t pharmacokinetic parameters of levodopa following oral administration of single-doses of Madopar® HBS 125 concomitantly with placebo or nebicapone

    Measured: pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 h post-dose

  4. Area under the plasma concentration versus time curve from time zero to infinity (AUC0-∞)

    Mean AUC0-00 pharmacokinetic parameters of levodopa following oral administration of single-doses of Madopar® HBS 125 concomitantly with placebo or nebicapone

    Measured: pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 h post-dose

  5. Apparent terminal half-life, calculated from ln 2/λz (t1/2)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BIA 3-202 and levodopa 100 mg / benserazide 25 mg in people with Parkinson's Disease (PD), run by Bial - Portela C S.A. at 1 site in Portugal.

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 11 inclusion and 21 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 14 Jun 2016. 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 Portugal. 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. Some participants in this study may receive a placebo. 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?

Maximum observed plasma drug concentration (Cmax) (time frame: pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 h post-dose). The study lists 5 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 14 Jun 2016.
