Milgamma® and Milgamma® Compositum Step-therapy in Patients With Acute Non-specific Low Back Pain Receiving Modern NSAID

The purpose of this study is to assess the effectiveness and safety of add-on Milgamma®/ Milgamma® compositum step-therapy in patients with acute non-specific low back pain receiving modern NSAIDs in routine medical practice.

This is a multi-centre observational prospective study that was planned for assessment the effectiveness of neurotropic vitamins therapy with Milgamma®/ Milgamma® compositum in combination with modern NSAIDs (preferential/selective cyclooxygenase-2 (COX-2) inhibitors) in patients with acute non-specific back pain. Approximately 500 adult out-patients with acute non-specific low back pain who have been prescribed therapy consisting of (1) modern NSAIDs (preferential/selective COX-2 inhibitors) or (2) modern NSAIDs (preferential/selective COX-2 inhibitors) + Milgamma® / Milgamma® compositum will be enrolled in the study. Each patient will be observed over a period of approximately 94 days. 9 visits/phone contacts are planned to be conducted during this period. Information about patient's condition, pain intensity, pain flare-ups, satisfaction with the treatment, patient's disability, therapy used for acute back pain treatment, data on safety will be collected during these contacts. Pain intensity will be measured with Numeric Rating Scale (NRS), patients' disability will be evaluated with Roland Morris disability questionnaire, patients' satisfaction with the treatment will be assessed with 5-point verbal rating scale. Safety assessment will be based on frequency and severity of adverse drug reactions recorded during the study.

Prior to the start of the study, neurologists (potential investigators) will be asked to fill out feasibility questionnaires to identify their individual routine practice regarding prescription or non-prescription of Milgamma® / Milgamma® compositum. Based on results of feasibility physicians will be divided to non-prescribers and prescribers of Milgamma® / Milgamma® compositum to the patients with acute non-specific low back pain. In each medical institution, such non-prescribers and prescribers will be proposed to participate in the study. Non-prescribers will be responsible for enrolling group (1) (NSAIDs alone), prescribers will be responsible for enrolling group (2) (NSAIDs + Milgamma® / Milgamma® compositum).

Eligibility Criteria:
Inclusion Criteria:

* Signed informed consent including data protection declaration according to the local legislation.
* Acute non-specific low back pain less than 21 days (= 3 weeks).
* Low back pain treatment with (1) modern NSAIDs (preferential/selective COX-2 inhibitors) or (2) modern NSAIDs (preferential/selective COX-2 inhibitors) + Milgamma®/ Milgamma® compositum prescribed (but not started yet) in frames of routine medical practice.
* Prescribed (but not started yet) step-therapy with Milgamma® to be followed by Milgamma® compositum in accordance with locally approved instruction for medical use (for the group planned to be treated with Milgamma®/ Milgamma® compositum step-therapy).
* Pain intensity according to Numerical Rating Scale (NRS) ≥4 points ≤9 at the time of enrollment.
* In case of presence of previous episodes of acute non-specific low back pain in medical history, the last one had resolved at least 30 days before the start of current episode.

Exclusion Criteria:

* History or presence of any disease that, in the opinion of the investigator, might confound the results of the study, poses an additional risk to the subject during participation in the study or can change pain perception (examples of such possible conditions: any malignancy, stomach ulcer, duodenal ulcer, chronic heart failure, bronchial asthma, psychiatry disorders, epilepsy, Parkinson Disease etc).
* Spinal surgery/rehabilitation in the last 12 months.
* Acute back pain that is attributable to any known or suspected specific identifiable cause (e.g. discogenic radiculopathy, spondylolisthesis, osteomalacia, inflammatory arthritis, metabolic, neurological diseases or tumor).
* Severe scoliosis.
* Use of NSAIDs or vitamins B within 2 months prior to enrollment into the study.
* Necessity to use myorelaxants or antidepressants for treatment of acute non-specific low back pain.
* Prior use of non-pharmacological treatment (physiotherapy, heat treatment (e.g. heat patch, hot water bottle) or topically applied medicinal products to the back area, procaine blocks) within the last 3 days before study entry.
