About this study

Official title: An Open-label Trial, Enrolling Subjects Aged 6 Years to Less Than 18 Years Suffering From Pain Requiring Prolonged Release Opioid Treatment, to Evaluate the Safety and Efficacy of Tapentadol PR Versus Morphine PR, Followed by an Open-label Extension

Tapentadol has already been studied in adults. This study is needed to find out if tapentadol works and is safe to use in children and adolescents with long-term pain.

Read the detailed description

During the first 2 weeks of the study (Part 1), participants were given either tapentadol or morphine prolonged-release (PR) tablets. Assignment was done randomly (like tossing a coin). The participant and the caregiver knew which medication the child was taking. The primary endpoint was based on data collected in Part 1 of this study.

If eligible and willing, participants from Part 1 could enter a 12 month follow-up period (Part 2). In Part 2 of this study, participants were either treated with tapentadol PR tablets or entered observations arms where they were not treated at all or with standard of care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tapentadol prolonged releaseDrug

    Also called Palexia®, Nucynta®, Yantil®

  • Morphine prolonged releaseDrug

Study groups in NCT02151682
Study groupRoleWhat they receive
Morphine prolonged-release (Part 1)Active comparator10 milligram (mg) or 30 mg tablets were taken orally twice daily. Starting doses varied from 10 to 40 mg morphine PR twice daily depending on participant's weight; if necessary, doses were gradually increased up to a maximum dose defined per weight group. The highest dose defined for participants weighing 55 kg and more was 200 mg per day.
Receives: Drug: Morphine prolonged release
Tapentadol prolonged-release (Part 1)Experimental25 mg or 100 mg tablets were taken orally twice daily. Starting doses varied from 25 to 100 mg tapentadol PR twice daily depending on participant's weight. If necessary, doses were gradually increased up to a maximum dose defined per weight group. The highest dose defined for participants weighing 55 kg and more was 500 mg per day.
Receives: Drug: Tapentadol prolonged release
Tapentadol in Part 2 after Tapentadol or Morphine in Part 1ExperimentalParticipants on tapentadol PR in Part 1 of the study continued on the current dose of tapentadol PR in Part 2 and if necessary could modify their tapentadol PR dosage. Participants who were randomized to morphine PR in Part 1 of the study were rotated to tapentadol PR in Part 2 with 70 percent of their current morphine equivalent dose or lower. The dosage could be increased gradually up to approximately 4.5 mg/kg body weight tapentadol PR twice daily.
Receives: Drug: Tapentadol prolonged release
Observation Period after Tapentadol in Part 1No interventionParticipants who completed tapentadol PR in Part 1 of the study or discontinued tapentadol treatment early in Part 1 could continue directly in the observation period in Part 2 for up to 12 months (with standard-of-care treatment if needed).
Observation Period after Morphine in Part 1No interventionParticipants who completed morphine PR treatment in Part 1 of the study or discontinued early from morphine treatment in Part 1 could continue directly in the observation period in Part 2 (with standard-of-care treatment if needed).
Observation Period after Tapentadol in Part 2No interventionParticipants who completed tapentadol PR or morphine PR treatment in Part 1 of the study could enter the Observation Period for up to 12 months (with standard-of-care treatment if needed) after they had discontinued from tapentadol PR treatment in Part 2.

What is being measured

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

  1. Number of Participants Classified as Responder (Part 1)

    The proportion of participants classified as responders was assessed and compared between the treatment groups.

    A participant was defined as responder if both of the following criteria were met:

    • Completion of the 14-day Treatment Period (Part 1).
    • One of the following calculated from the scheduled pain assessments ("pain right now") documented during the last 3 days of the Treatment Period:
    • Average pain less than 50 on a visual analog scale (VAS, range 0 [no pain] to 100 [pain as bad as it could be]) for participants aged 12 years to less than 18 years; or less than 5 on the Faces Pain Scale-revised (FPS-R, range 0 [no pain] and 10 [very much pain]) for participants aged 6 years to less than 12 years.
    • Average reduction from baseline of pain greater than or equal to 20 on a VAS for participants aged 12 years to less than 18 years; or greater than or equal to 2 on the FPS-R for participants aged 6 years to less than 12 years.

    Measured: From Day 1 up to Day 14 (End of Part 1)

Secondary outcomes (2)
  1. Extent of Constipation (Part 1)

    Constipation was assessed using the modified constipation assessment scale (mCAS). This is an 8-item questionnaire where the observer has scored constipation on a nominal scale (no Problem [score 0], some problem [score 1] or severe Problem [score 2]). The response to an item could also be scored as "unable to assess".

    The Total Score can vary from 0-16; the higher the Total Score the higher the extent of constipation. A positive change from Day 1 to Day 14 indicates a worsening, a negative change an improvement.

    Measured: From Day 1 to Day 14 (End of Part 1)

  2. Tolerability Over the Complete Trial Period

    Tolerability was assessed by the number of participants with exactly 1 to more than 5 treatment emergent adverse events (TEAE) by treatment group during the different trial periods, on a participant level.

    In addition, tolerability was assessed by the number of participants with TEAEs which were considered by the investigator to be at least possibly related to the treatment the participant received.

    Measured: Part 1: Day 1 (Start of Part 1) to Day 14; Part 2: Day 15 to Day 379 (End of Part 2)

Model description
There were 2 arms in Part 1: Randomization was carried out in blocks and in a 2:1 ratio (tapentadol PR to morphine PR). Participants were stratified using interactive response technology: by age group (6 years to less than 12 years and 12 years to less than 18 years, at the second visit \[Allocation Visit\]) so that at least 25% of participants were in the younger age group, and by underlying pain condition (cancer/non-cancer-related pain). There were 4 arms in Part 2: The investigators/participants decided if participants from Part 1 switched to or continued on tapentadol PR (tapentadol arm) or if they received no treatment/standard of care treatment if needed (2 direct observation arms following treatment in Part 1 and 1 observation arm after initial treatment with tapentadol in Part 2).

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Tapentadol prolonged release and Morphine prolonged release in people with Pain, run by Grünenthal GmbH at 23 sites in 10 countries.

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 18 inclusion and 34 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 12 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in France, Bulgaria, United Kingdom, Chile, Portugal and 5 more countries. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 12 Sep 2019). 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?

Number of Participants Classified as Responder (Part 1) (time frame: From Day 1 up to Day 14 (End of Part 1)). 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 12 Sep 2019.
