E.2.1 | Main objective of the trial |
The primary objective of this study is to compare the efficacy of ibuprofen/N-acetylcysteine fixed dose combination (FDC) over the reference ibuprofen monotherapy and N-acetylcysteine monotherapy in the time to resolution of symptoms of upper respiratory tract infection (URTI), defined as absence of fever and a score = 0 of each individual symptom on a 0-4 Likert rating scale. |
|
E.2.2 | Secondary objectives of the trial |
to evaluate: -The overall clinical efficacy (cure/improvement/failure) of ibuprofen/N-acetylcysteine FDC in comparison with individual components ibuprofen and N-acetylcysteine; -The efficacy of ibuprofen/N-acetylcysteine FDC on individual signs and symptoms of URTI in comparison with individual components ibuprofen and N-acetylcysteine; -The efficacy of ibuprofen/N-acetylcysteine FDC in the proportion of patients with resolution of symptoms of URTI in comparison with individual components ibuprofen and N-acetylcysteine; -The efficacy of ibuprofen/N-acetylcysteine FDC on cold symptoms, as evaluated with the Wisconsin Upper Respiratory Symptoms Survey (WURSS-11), in comparison with individual components ibuprofen and N-acetylcysteine; -The efficacy of ibuprofen/N-acetylcysteine FDC in the patient's perception of the severity of symptoms, in comparison with individual components ibuprofen and N-acetylcysteine; -The safety of the investigational study drugs. |

E.5 End points |
E.5.1 | Primary end point(s) |
Time to resolution of symptoms of URTI, defined as absence of fever and a score = 0 of each individual sign and symptom (productive cough, fever, cold symptoms, sore throat, shortness of breath and limitation in daily activities) on a 0-4 Likert rating scale. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Visit 2 or early termination visit. If patients terminate early before Visit 2, Visit 2 should be arranged and procedures will be those scheduled for Visit 2/early termination visit |
|
E.5.2 | Secondary end point(s) |
-Investigator's overall assessment of efficacy: cure (complete disappearance of signs and symptoms of inflammation), improvement (non-complete resolution of signs and symptoms of inflammation), failure (persistency or worsening of signs and symptoms of inflammation); -Change from baseline of fever, and of total score and score of individual signs and symptoms of URTI (productive cough, cold symptoms, sore throat, shortness of breath and limitation in daily activities), evaluated by patients on a 0-4 point Likert scale (0 = no symptom; 1 = mild symptom; 2 = moderate symptom; 3 = severe symptom; 4 = very severe symptom) using a daily diary. Changes from baseline will be evaluated as score and area under the curve (AUC) of individual signs and symptoms of URTI; -Proportion of patients with resolution of symptoms, defined as absence of fever and a score = 0 of each individual signs and symptom of URTI; -Changes from baseline on total score and single items of the Wisconsin Upper Respiratory Symptoms Survey (WURSS-11); -Changes from baseline in the patient's perception of the severity of symptoms of URTI, as evaluated by means of a 100 mm visual analogue scale (VAS); -Global assessment of efficacy by patient, performed at the end of treatment (Day 7 ± 1), and at the end of the follow up period by phone(Day 14 ± 2), by means of a 0-4 point Likert scale (0 = poor; 1 = slight; 2 = moderate 3 = good; 4 = excellent). The end of treatment may be anticipated at any time prior to Day 7 ± 1 for symptom resolution or safety reasons. In such cases, the overall patient efficacy assessment will be maintained on Day +7 ± 2 after the interruption. |
