April 12, 2022 updated by: Laboratorios Silanes S.A. de C.V.

Confirmatory Efficacy and Safety Study of the Fixed-dose Combination of Etoricoxib / Tramadol Versus Acetaminophen / Tramadol for the Management of Acute Low Back Pain.

Phase IIIb, longitudinal, multicenter, randomized, open-label clinical trial to evaluate the efficacy and safety of the fixed-dose combination of etoricoxib 90 mg and tramadol 50 mg compared with fixed-dose therapy of acetaminophen 325 mg and tramadol 37.5 mg for the management of acute low back pain.

Detailed Description

Patients with back pain from the level of the lowest rib to the gluteal crease, with or without radiation to the legs, as a first-time episode or after another at least 6 months before and lasting no more than 6 weeks, that in the opinion of the doctor requires treatment with the combination of an anti-inflammatory and an analgesic. Study to evaluate the efficacy and safety of the fixed-dose combination of etoricoxib 90 mg and tramadol 50 mg compared with the fixed-dose therapy of acetaminophen 325 mg and tramadol 37.5 mg for the management of acute low back pain. Evaluate and compare the average change in pain reported through the VAS at 3, 5 and 7 days with respect to its baseline measurement by treatment group. An exploratory analysis of the data will be carried out to identify aberrant, outliers, or missing values. To present the numerical variables, the measures of central tendency and dispersion appropriate to the distribution of the data will be used and the categorical variables will be expressed as frequency and percentage.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average change in reported pain
Time Frame: Baseline, 3, 5 and 7 days.
Compare the average change in pain reported through the VAS (Visual Analog Scale) per treatment group. In a straight 10 centimeter line in which one end means no pain and the other end means the worst pain imaginable, the participants mark the amount of pain feeling at that moment
Baseline, 3, 5 and 7 days.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of patients with a 30% reduction in pain intensity
Time Frame: Baseline and 7 days.
Describe the proportion of patients who reported a 30% reduction in pain intensity measure by the VAS (Visual Analog Scale) per treatment group. In a straight 10 centimeter line in which one end means no pain and the other end means the worst pain imaginable, the participants mark the amount of pain feeling at that moment.
Baseline and 7 days.
Degree of disability due to low back pain
Time Frame: Baseline and 7 days.
Evaluate the degree of disability due to low back pain measured through the Oswestry disability scale per treatment group. It measures the limitations in daily activities in the presence of pain in the lumbar region, consists of 10 questions with 6 possible answers considering the intensity of the pain, basic activities of daily life such as: personal care, sexual activity, sleep, travel and social life.
Baseline and 7 days.
Degree of inability to perform daily activities
Time Frame: Baseline and 7 days.
Assess the degree of inability to perform daily activities through the Roland-Morris scale per group. It´s a self-applied scale where the extreme values range between 0 (absence of disability) and 24 (maximum disability) and is categorized according to the relevance of the score obtained where the optimal threshold of variation is 3 and 4 points.
Baseline and 7 days.
Adverse events
Time Frame: 7 days.
Compare the frequency of adverse events presented during the study between the treatment groups.
7 days.
