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
  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Female subjects ≥ 18 years on the day of consent.
  • Willing and able to provide written informed consent for this study.
  • Subjects are scheduled to have a total or subtotal abdominal hysterectomy under general anasethesia via a Pfannenstiel incision.
  • The elective procedure (total or subtotal hysterectomy with or without salpingo-oophorectomy) must be for benign conditions within 28 days of screening. Subjects with stage 0 carcinoma in situ of cervix, endometrial hyperplasia or clinically staged 1A or 1B endometrial cancer are allowed to participate.

  • Good general health as judged by Investigators on the basis of medical history and physical examination.
  • Willingness to comply with the study procedures and requirements.
  • Additional Inclusion Criteria after Surgery:
  • Abdominal hysterectomy completed without any immediate complication.
  • Tolerating oral fluids, no uncontrolled nausea/vomiting and ready to take oral analgesia.

  • Any history of drug or alcohol abuse, misuse, physical or psychological dependence, mood changes, sleep disturbance and functional capacity which have an impact on pain perception.
  • Significant neurological or psychiatric disorders including mental instability (unrelated to the pain) that could interfere with pain assessment; other pre-existing or new non-abdominal/pelvic pain that might impair the assessment of the nociceptive pain.
  • Any medical history of significant and/or inadequately controlled cardiovascular (uncontrolled high blood pressure, high risk of cardiovascular events, severe heart failure), pulmonary, hematologic, (including coagulopathy/bleeding disorders), neurological (e.g. subjects with epilepsy or those susceptible to seizures), liver disease (e.g. severe hepatic impairment), kidney disease (e.g. serum creatinine level greater than 1.5 times the upper limit of normal, impaired renal function in subjects taking diuretics, ACE-inhibitors, or angiotensin II antagonists), endocrine, immunologic, dermatologic painful conditions or any other conditions that may compromise the ability of the subject to participate in the study or might interfere with drug absorption, distribution, metabolism or excretion.
  • Previous randomisation in this study.
  • Subjects who participated in a clinical research study involving a new chemical entity or an experimental drug within 30 days of study entry (defined as the start of the Screening Period).
  • Subjects who were treated regularly with opioid analgesic or NSAIDs within 30 days prior to screening or who have received a long-acting NSAID within three days prior to the start of the surgery.

About this study

Official title: A Randomized, Double-Blind, Multicenter, Placebo- and Active Comparator-Controlled Study to Evaluate Efficacy and Safety of MR308 in the Treatment of Acute Pain After Abdominal Hysterectomy Surgery Under General Anaesthesia (STARDOM2).

The MR308-3502 study is a multicenter double-blind, randomised, placebo- and active comparator-controlled study in female subjects to evaluate the efficacy and safety of MR308 with acute pain after TAH or STAH (total or subtotal abdominal hysterectomy).

Read the detailed description

This is a multicenter double-blind, randomised, placebo- and active comparator-controlled study in female subjects to evaluate the efficacy and safety of MR308 with acute pain after total or subtotal abdominal hysterectomy (TAH or STAH).

The screening Visit (Visit 1) can take place up to 28 days before the planned TAH or STAH. The surgery will be performed at Visit 2. Visit 2 consists of three different sections, a part before the surgery, the surgery and post surgery. On the next Day (Visit 3) subjects will qualify for further participation by regular measurements of their pain. Subjects meeting all eligibility criteria, such as defined pain levels, will be randomised to one of six treatment groups and be given IMPs for 120h. Subjects who will not be randomised are screen failures and will be given standard care as per local practice.

Visits 4, 5, 6 ,7 and 8, one to five days after randomisation will be performed to record efficacy and safety parameters.

The last dose of IMP should be taken by the subject about 120h after the initial dose and before Visit 8 (Completion/Discontinuation Visit) is performed.

The Adverse Event (AE) Follow up Visit (Visit 9) is the last study visit and should not be done earlier than seven days after the subject's last dose of IMP. It can be performed by telephone.

What is being measured

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

  1. Efficacy of MR308 doses in the treatment of moderate to severe acute pain, based on the Sum of Pain Intensity Differences (SPID) from 0-4 hours.

    The primary efficacy endpoint is the Sum of Pain Intensity Differences over 0-4 hours (SPID4). SPID4 is derived as the weighted Sum of Pain Intensity Differences (baseline pain - current pain), measured at different time points via the PI-VAS. Time between two consecutive measurements will be used for weighting. Larger values indicate larger pain relief.

    Measured: 0-4 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing MR308 in people with Acute Pain, run by Mundipharma Research GmbH & Co KG at 8 sites in 8 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 14 inclusion and 25 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 20 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Belarus, Bulgaria, Canada, Hungary, Latvia and 3 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. 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 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?

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?

Efficacy of MR308 doses in the treatment of moderate to severe acute pain, based on the Sum of Pain Intensity Differences (SPID) from 0-4 hours. (time frame: 0-4 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03062644, which also lists 2 linked publications.

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 20 Sep 2018.
