Study summary

This study is being conducted to compare intrathecal morphine using the commercially available intrathecal drug delivery systems (IDDS), and conventional medical management (CMM) in subjects with non-cancer, refractory chronic pain.

Read the detailed description

This study will evaluate the following objectives:

Primary objective:

  1. To compare the change in pain intensity from baseline based on the Numeric Rating Scale [NRS] between subjects randomized to the IDDS group and subjects randomized to the CMM group.The comparison will be conducted at 3, 6, 9 and 12 months following enrollment. The evaluation at 6 months will be considered the primary time point for evaluation.

Secondary objectives:

For each of the following secondary objectives, the comparisons between the IDDS group and CMM group will be made using the intra-subject change from baseline as the dependent variable.

  1. Compare the subject reported PROMIS 29 between the IDDS group and CMM group. Individual subject scores recorded at baseline and months 3, 6, 9 and 12.
  2. Compare the accrued cost of therapy for pain control including those related to adverse events, ED visits, cost of medications between the IDDS group and CMM group
  3. Compare the number of other concurrent treatments performed on each subject between the IDDS group and CMM group. Individual subject counts recorded at months 3, 6, 9 and 12 will be compared.

Additional safety objective:

  1. To characterize pain and device related adverse events for all subjects throughout the study through completion of 12 month follow-up or subject exit.

    At the Baseline Visit or prior to Randomization, a subject will be excluded from continued participation if the subject has:

  9. Subjects that have a mean of the reported 12 hour "average" NPRS responses of \< 6 on an eleven-point scale (0 to10) rated over the 5 days prior to the Baseline Visit (as recorded in the electronic Study Diary) in the absence of intolerable side effects as documented in the medical history
  10. Subjects with a negative urine test for opioids at Baseline
  11. Subjects with a positive Pregnancy test, if applicable
  12. Subjects that failed the intrathecal trial during Screening
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Compare the change in Numeric Pain Rating Scale between the IDDS group and the CMM group

    The Numeric Pain Rating Scale (NPRS) is a 0-10 numeric pain rating scale (11 point scale), where a higher scores equates to more pain. The primary endpoint for this post-marketing study is the comparison of the NPRS between the IDDS group and the CMM group collected in the Study Diary at various time points.

    Time frame: Comparisons will be done prior to baseline visit and at 3, 6, 9 and 12 month visits.

Secondary outcomes

  1. Compare the change in PROMIS 29 scores between the IDDS group and CMM group

    Compare the subject reported Patient-Reported Outcomes Measurement Information System (PROMIS) 29 between the IDDS group and CMM group. PROMIS 29 assesses pain intensity using a 0-10 numeric rating scale (11 point scale), where a higher score equates to more pain. Other health domains are scored using a Likert scale, where higher scores represent more of the specific domain being measured. The other health domains that are scored are: depression; anxiety; physical function; pain interference; fatigue; sleep disturbance; and ability to participate in social roles and activities.

    Time frame: Individual subject scores recorded at baseline visit and at 3, 6, 9 and 12 month visits.

  2. Comparison of the accrued cost of therapy for pain

    Compare the accrued cost of therapy for pain control including those related to adverse events, ED visits, cost of medications between the IDDS group and CMM group.

    Time frame: Cost of therapy will be obtained at 3, 6, 9 and 12 month visits.

  3. Comparison of other concurrent treatments

    Compare the number of other concurrent treatments performed on each subject between the IDDS group and CMM group.

    Time frame: Individual subject counts recorded at 3, 6, 9 and 12 month visits will be compared.

Ran from Jun 2019 to primary completion in Apr 2022, 34 months.

Of 26 interventional studies with no phase under Pain, Intractable, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 34. This study's 34 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 18, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
