About this study

Official title: Investigation of the Pharmacokinetics of a Transtec® 35 µg/h Transdermal Patch Application for 96 Hours and a Patch Application for 72 Hours in an Open, Randomised, Single Application, Two-period Crossover, Phase I Study in 30 Healthy Male Volunteers

The purpose of the study was to investigate the pharmacokinetics (i.e. the uptake, distribution and elimination from the body) of dermally applied buprenorphine during and after different application periods, i.e., a 96-hour and a 72-hour application of the Transtec (Registered Trademark) patch (release rate 35 micrograms per hour [µg/hour]). In the Transtec summary of product characteristics (prescribing information for the physician), the wearing time per patch is restricted to three days (72 hours) after which the patch has to be replaced. However, market experience has shown that the Transtec patches are sometimes worn for a period longer than three days, i.e. they sometimes happen to be only replaced every four days. There was currently no data available as how to evaluate this longer wearing period.

What is being measured

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

  1. Pharmacokinetic parameter: AUC48-72 for buprenorphine

    Partial area under the plasma concentration-time curve (from 48 hours after application until 72 hours after application).

    Measured: From 48 hours to 72 hours

  2. Pharmacokinetic parameter: AUC72-96 for buprenorphine

    Partial area under the plasma concentration-time curve (from 72 hours after application until 96 hours after application).

    Measured: From 72 hours to 96 hours

Secondary outcomes (8)
  1. Pharmacokinetic parameter: Cmax for buprenorphine

    Maximum observed plasma concentration of the measured concentration-time profile. Blood samples will be taken for the determination of buprenorphine plasma concentrations at distinct time points: Before application to 144 hours after patch application. If the patch was applied for 96 hours, additional samples were taken at 156 and 168 hours after application. For the analysis of buprenorphine in human plasma, a validated liquid chromatography mass spectrometry (LC/MS/MS)-method will be used.

    Measured: Before application and after 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104,112,120,132,144,156, and 168 hours

  2. Pharmacokinetic parameter: tmax for buprenorphine

    Time of maximum concentration, time after transdermal patch application at which Cmax occurs.

    Measured: Before application and after 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104,112,120,132,144,156, and 168 hours

  3. Pharmacokinetic parameter: AUC0-t for buprenorphine

    Area under plasma concentration-time curve from application until the last sampling point (t) with a quantifiable concentration, calculated by the linear/log trapezoidal method, i.e., the linear trapezoidal rule is applied up to Cmax and then the log trapezoidal rule is applied for the remainder of the curve.

    Measured: Before application and after 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104,112,120,132,144,156, and 168 hours

  4. Pharmacokinetic parameter: t1/2z for buprenorphine

    Apparent terminal elimination half-life.

    Measured: Before application and after 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104,112,120,132,144,156, and 168 hours

  5. Pharmacokinetic parameter: AUC0-inf for buprenorphine

    Area under the plasma concentration-time curve extrapolated to infinity.

    Measured: Before application and after 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104,112,120,132,144,156, and 168 hours

  6. Incidence of treatment emergent adverse events

    Number of adverse events and number of participants with adverse events.

    Measured: From patch application (Day 1) until Final check (Day 12)

  7. Characteristics of treatment emergent adverse events

    Adverse events with information on intensity, seriousness, relationship to the investigational product, outcome and action taken will be determined.

    Measured: From patch application (Day 1) until Final check (Day 12)

  8. Onset and duration of treatment emergent adverse events

    Adverse events with information on onset and duration to the investigational product will be determined.

    Measured: From patch application (Day 1) until Final check (Day 12)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Transtec 35 µg/hour transdermal patch in people with Pain and Pharmacokinetics, run by Grünenthal GmbH at 1 site in Germany.

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 10 inclusion and 18 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 10 Dec 2018. 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 Germany. 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?

Pharmacokinetic parameter: AUC48-72 for buprenorphine (time frame: From 48 hours to 72 hours). 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 10 Dec 2018.
