About this study

Official title: Efficacy and Safety of Different Dosage Regimens of the Combination Methocarbamol/Paracetamol in Acute Low Back Pain (LBP): MioPain Study

The aim of the study is to evaluate the efficacy and safety of different dosage regimens of the combination methocarbamol/paracetamol in the treatment of patients with acute non-specific Low Back Pain.

Read the detailed description

This is a Phase IV, randomized, open-label, parallel-group, multicentre study.

A total of 192 patients of both sexes will be enrolled in the study and will be randomized 1:1 to one of the following 2 treatment groups:

  • Group 1: methocarbamol 380 mg/paracetamol 300 mg (2 oral tablets 4 times/day)
  • Group 2: methocarbamol 380 mg/paracetamol 300 mg (2 oral tablets 6 times/day) The expected duration of patient participation into the trial (from ICF signature up to any applicable follow up) is 8 days (± 1). Patients enrolment will be competitive among clinical sites.

The primary endpoint will be the Time to complete relief of pain, defined as the time when the complete pain relief is reached. A Complete pain relief is defined as a VAS score ≤ 5 mm at two consecutive assessments starting from Day1 up to Day7 (±1).

What is being measured

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

  1. Time to complete releif of pain.

    The Time to complete relief of pain is defined as the time when the complete pain relief is reached.

    A Complete pain relief is defined as a Visual Analogue Scale score ≤ 5 mm at two consecutive assessments starting from Day1 up to Day7 (±1).

    Measured: from Day1 up to Day7 (±1).

Secondary outcomes (7)
  1. Change in Low Back Pain intensity at Visit 0 and Visit 1

    Change in Low Back Pain intensity at Visit 0 and Visit 1, measured by 0-10 cm (100 mm) Visual Analogue Scale, stretching from 0 "no pain" to 10 "pain as bad as it could be".

    Measured: Day 0 and Day 4 (±1).

  2. Change in Low Back Pain intensity at Visit 0 and Final Visit

    Change in Low Back Pain intensity at Visit 0 and Final Visit, measured by 0-10 cm (100 mm) Visual Analogue Scale, stretching from 0 "no pain" to 10 "pain as bad as it could be".

    Measured: Day 0 and Day 8 (±1).

  3. Change in the degree of improvement in the hand-to-floor distance

    The Hand-to-floor distance, also called fingertip-to-floor test or mobility assessment is the vertical distance between the tip of the middle finger and the floor measured by a simple cm graduated bar (0 value at floor).

    The patient will be asked to bend forward as far as possible and try to touch the floor with his/her fingers, while maintaining the knees, arms, and fingers fully extended.

    Measured: Day 0, Day 4 and Day 8 (±1).

  4. Change in the functional disability

    The Functional disability is assessed by the Oswestry Disability Index (ODI) that allows to obtain information on how acute Low Back Pain affects ability to manage patients Activities of Daily Living (ADL).

    The Oswestry Disability Index contains 10 sections. For each section the total possible score is 5: if the first statement is marked, the section score is=0; if the last statement is marked, it is=5. The total score of all sections as a percentage of the total achievable score is the Oswestry Disability Index score.

    Measured: Day 0, Day 4 and Day 8 (±1).

  5. Change in the Patients' Global Impression of Change scale score

    The Patients' Global Impression of Change (PGIC) scale reflects a patient's belief about the efficacy of treatment evaluating all aspects of patient's health and quality of life (QoL).

    It is a 7-point scale depicting a patient's rating of overall improvement: "no change", "almost the same", "a little better", "somewhat better", "moderately better", "better", or "a great deal better".

    Measured: Day 0 and Day 8 (±1).

  6. Change in the Clinical Global Impression-Improvement scale score

    The Clinical Global Impression-Improvement (CGI-I) scale provides an overall clinician-determined summary evaluation of the treatment.

    It is a 7-point scale: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from the initiation of treatment; 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment.

    Measured: Day 0 and Day 8 (±1).

  7. Monitoring frequency of adverse events (AEs)

    Safety will be assessed by monitoring the frequency of adverse events in each treatment group.

    All AEs will be coded using MedDRA (Medical Dictionary for Regulatory Activities).

    Measured: 8 (±1) days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 380 mg/300 mg comprimidos metocarbamol/paracetamol - 4 times daily and 380 mg/300 mg comprimidos metocarbamol/paracetamol - 6 times daily in people with Low Back Pain, run by Aziende Chimiche Riunite Angelini Francesco S.p.A at 3 sites in Italy.

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 7 inclusion and 40 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: stopped early, as of the sponsor's last update on 31 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Italy. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 was stopped early (reason given: The study had to be closed because it was not feasible to reach the estimated sample size.). Results are not available in the source record.

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?

Time to complete releif of pain. (time frame: from Day1 up to Day7 (±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 31 Jan 2025.
