Clinical Trial Summary

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.


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).

Any other condition that, in the opinion of the Investigator, interferes with the study endpoints/procedures and does not justify the inclusion of the patient in the study. 7. Current use of full, regular, recommended doses of any skeletal muscle relaxants/non - opioid analgesics/anti-inflammatory/NSAIDs in the 6 hours prior to the screening visit. Use is forbidden for the entire trial duration. 8. Current use of full, regular, recommended doses of or any medication that can alter the perception of pain (e.g., opioids, heparinoids, psychotropic agents, anti-H1 agents or glucocorticosteroids, etc.), in the 24 hours prior to the screening visit. Use is forbidden for the entire trial duration. Chronic intake of low doses of acetylsalicylic acid, i.e., =162 mg/daily, taken for at least 30 days prior to the first dose of study medication for non-analgesic reasons could be continued for the duration of the study. 9. Current use of the following medications (use is forbidden for the entire trial duration): • systemic corticosteroids; - other drugs containing paracetamol; - central nervous system (CNS) depressants and stimulants, including barbiturates, anaesthetics, appetite suppressants, anticonvulsants and lamotrigine (with the exception of therapeutic doses of benzodiazepines used as hypnoinducers in patients stabilised for more than one month since the screening visit); - anticholinergic drugs; psychotropic drugs; anti-cholinesterase drugs, pyridostigmine; - oral anticoagulants; - chloramphenicol; rifampicin; zidovudine; - loop diuretics; - isoniazid; probenecid; - propranolol; - antiemetics; - metoclopramide; domperidone; - ion exchange resins (e.g. cholestyramine). 10. Patients undergoing physiotherapy, osteopathy or chiropractic treatments aimed to reduce LBP. 11. Patients treated with invasive procedures aimed to reduce LBP (e.g., epidural injections, spinal cord stimulation therapy). 12. History of alcoholic/substance abuse. Use of alcohol is forbidden during the entire duration of the study. 13. Inability to comply with the protocol requirements, instructions or study-related restrictions (i.e., uncooperative attitude, inability to return for study visits, unlikelihood of completing the clinical study); vulnerable patients (i.e., persons kept in detention). 14. Patients involved in the conduct of the study (i.e., Investigator or his/her deputy, first grade relatives, pharmacist, assistant or other personnel). 15. Participation to an interventional clinical trial within 3 months prior to Visit 0.

Outcome

Type Measure Description Time frame Safety issue
Primary 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).
from Day1 up to Day7 (±1).
Secondary 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". Day 0 and Day 4 (±1).
Secondary 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". Day 0 and Day 8 (±1).
Secondary 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.
Day 0, Day 4 and Day 8 (±1).
Secondary 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.
Day 0, Day 4 and Day 8 (±1).
Secondary 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".
Day 0 and Day 8 (±1).
Secondary 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.
Day 0 and Day 8 (±1).
Secondary 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).
8 (±1) days
