The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43874   clinical trials with a EudraCT protocol, of which   7294   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Low back pain (LBP) is one of the most frequent and disabling health problems. It is estimated that about 80% of adults will experience an episode of acute or chronic LBP at least once during their lifetime
    The mechanism underlying acute LBP may be disk-, muscle- or posterior articulation-related. The aim of the treatment is always to obtain early and maximum relief of the local and regional pain, as well as to improve mobility and physical function.
    La lombalgia è uno dei problemi di salute più frequenti e invalidanti. Si stima che circa l'80% degli adulti sperimenterà un episodio di lombalgia acuta o cronica almeno una volta durante la sua vita.
    Il meccanismo alla base della lombalgia acuta può essere legato al disco, al muscolo o all'articolazione posteriore. L'obiettivo del trattamento è sempre quello di ottenere un sollievo precoce e massimo del dolore locale e regionale, nonché di migliorare la mobilità e la funzionalità fisica.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the study is to demonstrate the superiority of the test fixed combination of diclofenac 75 mg + thiocolchicoside 4 mg given via intramuscular (i.m.) injection over the reference diclofenac 75 mg i.m. and the superiority of both test and reference over placebo i.m., in relieving pain symptoms in adult patients with acute moderate-severe low back pain (LBP) after 48 (± 2) hours from the start of treatment (2 i.m. injections on Day 1 and Day 2 of all investigational medicinal products). Efficacy will be determined by a 100-mm Visual Analogic Scale (VAS) for the assessment of pain
    L'obiettivo primario dello studio è dimostrare la superiorità della combinazione fissa del test, diclofenac 75 mg + tiocolchicoside 4 mg, somministrata tramite iniezione intramuscolare (i.m.) rispetto al diclofenac reference 75 mg i.m. e la superiorità di entrambi test e riferimento rispetto al placebo i.m. nell'alleviare la sintomatologia dolorosa in pazienti adulti con lombalgia acuta da moderata a severa dopo 48 (± 2) ore dall'inizio del trattamento (2 iniezioni i.m. il Giorno 1 e il Giorno 2 dei prodotti medicinali sperimentali). L'efficacia sarà determinata mediante Scala Analogica Visiva (VAS) di 100 mm per la valutazione del dolore
    E.2.2Secondary objectives of the trial
    The secondary objectives of the study are to compare the efficacy of test, reference end placebo groups in:
    •Pain symptoms (VAS for pain) at all the other daily time points, up to 7 days from the start of treatment, i.e. 5 days after the 2nd i.m. injection;
    •Proportion of responder patients after 48 hours (Day 3) and 7 days (Day 7) from the start of treatment;
    •Muscle contracture (Schober index);
    •Disability due to LBP, as measured using the Roland Morris disability questionnaire;
    •Consumption of rescue medication (oral diclofenac 50 mg tablet);
    •Tolerability and safety of the IMPs, assessed through summaries of adverse events, the frequency of discontinuation of treatment due to adverse events, laboratory evaluations, electrocardiograms (ECGs), and vital signs (sitting heart rate, sitting systolic/diastolic blood pressure, respiratory rate, body temperature).
    Gli obiettivi secondari dello studio sono confrontare l'efficacia del gruppo test, riferimento e placebo in merito a quanto segue:
    •Sintomi del dolore (VAS per dolore) in tutti gli altri momenti della giornata, fino a 7 giorni dall'inizio del trattamento, ovvero 5 giorni dopo la 2a iniezione i.m.;
    •Percentuale di pazienti che rispondono dopo 48 ore (Giorno 3) e 7 giorni (Giorno 7) dall'inizio del trattamento;
    •Contrattura muscolare (indice di Schober);
    •Disabilità dovuta alla lombalgia, misurata utilizzando il questionario sulla disabilità di Roland Morris;
    •Consumo del farmaco di soccorso (diclofenac orale compresse da 50 mg);
    •Tollerabilità e sicurezza dei medicinali sperimentali (IMP), valutata attraverso elenco degli eventi avversi (EA), frequenza di interruzione del trattamento a causa di eventi avversi, valutazioni di laboratorio, ECG e segni vitali (frequenza cardiaca da seduti, pressione sistolica/diastolica da seduti, frequenza respiratoria, temperatura corporea).

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint of the study will be the sum of pain intensity difference (SPID) from baseline (Day 1) to Day 3 (4 measurements every 12 hours, 2 in the morning and 2 in the evening) in VAS for pain score at rest. VAS for pain will be measured by patients on Day 1 pre-administration (baseline) and post-baseline measurements will be repeated by patients twice daily (morning and evening). The pain intensity difference (PID) from baseline will be calculated for each of the 4 measurements performed up to Day 3 (2 measurements in the morning and 2 in the evening) by subtracting each pain intensity (PI) score from the baseline PI score, as measured by the patient on a 0-100 mm VAS (0 mm: no pain; 100 mm: maximum unbearable pain). Then the overall SPID will be calculated for the evaluation of the primary efficacy endpoint.
    L'endpoint primario di efficacia dello studio sarà la somma della differenza di intensità del dolore (SPID) dal basale (Giorno 1) al Giorno 3 (4 misurazioni ogni 12 ore, 2 al mattino e 2 alla sera) nella VAS per il punteggio del dolore a riposo. La VAS per il dolore sarà misurata dai pazienti al Giorno 1 prima della somministrazione (basale) e le misurazioni post-basale saranno ripetute dai pazienti due volte al giorno (mattina e sera). La differenza di intensità del dolore (PID) rispetto al basale sarà calcolata per ciascuna delle 4 misurazioni eseguite fino al Giorno 3 (2 misurazioni al mattino e 2 alla sera) sottraendo ogni punteggio di intensità del dolore (PI) dal punteggio basale, come misurato dal paziente sulla scala VAS 0-100 mm (0 mm: nessun dolore; 100 mm: massimo dolore insopportabile). Quindi verrà calcolato la SPID complessivo per la valutazione dell'endpoint primario di efficacia.

    E.5.2Secondary end point(s)
    Key secondary efficacy endpoint
    Changes from baseline to Day 3 and Day 7 of muscle contracture (Schober index).
    Other secondary efficacy endpoints
    • SPID vs. baseline based on morning and evening daily measurements of VAS for pain at all the other daily time points, up to 7 days from the start of treatment, i.e. 5 days after the 2nd i.m. injection;
    • Proportion of responder patients after 48 hours (Day 3) and 7 days (Day 7) from the start of treatment. A responder is defined as a decrease of VAS for pain = 50% vs. baseline (Day 1, pre-administration). Patients who will intake rescue medication within 48 hours from the start of treatment will be considered as non-responder;
    • Changes from baseline to Day 3 and Day 7 of disability due to LBP, as measured using the 24-item Roland Morris disability questionnaire;
    • Use of rescue medication (diclofenac 50 mg tablet): number and percentage of users, number of days with use and number of used tablets, up to Day 3 and up to Day 7;
    • Time elapsed from date/hour of first study drug administration to first intake of the rescue medication.
    Safety endpoints
    • Frequency of adverse events and frequency of discontinuation of treatment due to adverse events
    • Changes from baseline of safety laboratory parameters;
    • Electrocardiogram (ECG);
    • Changes from baseline of vital signs (sitting heart rate, systolic/diastolic blood pressure, respiratory rate, body temperature);
    • Changes from baseline of findings at clinical examination.
    Endpoint principale secondario di efficacia
    Cambiamenti della contrattura muscolare dal basale al Giorno 3 e al Giorno 7 (indice di Schober).
    Altri endpoint secondari di efficacia
    • SPID rispetto al basale basato sulle misurazioni giornaliere mattutine e serali della VAS per il dolore a tutte le altre tempistiche giornaliere, fino a 7 giorni dall'inizio del trattamento, ovvero 5 giorni dopo la 2a iniezione i.m.;
    • Percentuale di pazienti responder dopo 48 ore (Giorno 3) e 7 giorni (Giorno 7) dall'inizio del trattamento. Un responder è definito come un paziente con una diminuzione della VAS per il dolore = 50% rispetto al basale (Giorno 1, pre-somministrazione). I pazienti che assumeranno farmaci di soccorso entro 48 ore dall'inizio del trattamento in studio saranno considerati non-responder;
    • Cambiamenti dal basale al Giorno 3 e al Giorno 7 della disabilità dovuta alla lombalgia, secondo quanto misurato utilizzando il questionario sulla disabilità Roland Morris a 24 punti;
    • Uso del farmaco di soccorso (diclofenac 50 mg compresse): numero e percentuale di utilizzatori, numero di giorni di utilizzo e numero di compresse utilizzate, fino al Giorno 3 e fino al Giorno 7;
    • Tempo trascorso dalla data/ora della prima somministrazione del farmaco in studio alla prima assunzione del farmaco di soccorso.
    Endpoint di sicurezza
    • Frequenza degli eventi avversi e frequenza dell'interruzione del trattamento a causa di eventi avversi
    • Modifiche rispetto al basale dei parametri di laboratorio di sicurezza;
    • Elettrocardiogramma (ECG);
    • Cambiamenti rispetto al basale dei segni vitali (frequenza cardiaca a riposo, pressione sanguigna sistolica/diastolica, frequenza respiratoria, temperatura corporea);
    • Cambiamenti rispetto al basale dei risultati all'esame clinico.
