Clinical Trial Summary

Aim of this study is to investigate safety and efficacy of A. Vogel Sore throat lozenges for the treatment of of acute sore throats


Description:

75 patients aged 12-75 years with acute sore throats (symptoms not older than 48 h) were recruited by the study site/CRO via local general practitioners and are allocated to acute treatment with A. Vogel Sore throat lozenges. The patients who are confirmed to meet the study entry criteria and after having given written informed consent will be assigned to receive a study treatment according to study procedures described in the study plan. The patients will visit study site twice. At the first visit (Visit 1) a screening will be performed to finally decide if patient will be included/excluded in the study. Then he or she will be taking one single lozenge under supervision of the investigating physician and acute efficacy/safety ratings recorded before intake and repeatedly every 15 minutes for 90 minutes after intake of first lozenge. He or she will be supplied with the remaining 19 lozenges in a bottle and provided with patient diaries for home recording of efficacy/safety. After four days (max 5 days) or until complete resolution of symptoms the patients were obliged to return to the study centre for final visit 2. Daily ratings of efficacy/safety was done by the patient once in the morning and once in the evening. Daily dosage was 5 lozenges per day every 3rd hour during daytime. At final visit 2, patients will be evaluated physically by the physician at the study centre and again assessed for safety/efficacy parameters. At last, patients returned their patient diaries and remaining study medication before compensation is handed out and patients finally excluded from the study.

Outcome

Type Measure Description Time frame Safety issue
Primary Rate of "good" and "very good" tolerability ratings vs. "moderate" and "bad" tolerability ratings as assessment by a physician Assessment of safety after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 by physician with very good, good, moderate, bad 4 days
Secondary Change of acute throat pain on a visual analog scale (VAS) Change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) within 90 minutes compared to baseline 90 min
Secondary Rate and number of treatment responders at day 1,2,3,4 Rate and number of Treatment responders expressed on a Tonsillopharyngitis Score (TSS) measuring change of sore throat symptoms at day 1,2,3,4 (Responder=TSS reduction by 50% compared to baseline). The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe. 4 days
Secondary Total change of Tonsillopharyngitis Score (TSS) at the end of treatment Change of Tonsillopharyngitis Score (TSS) total at the end of treatment at day 4 as compared to baseline measurement. The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe. 4 days
Secondary Total reduction of pain score Change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) on the evenings of day 1,2,3,4 compared to baseline 4 days
Secondary Absolute and relative distribution of individual Tonsillopharyngitis Score (TSS) symptoms Absolute and relative distribution of the single symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) from the Tonsillopharyngitis Score (TSS) on day 1,2,3,4 compared to baseline 4 days
Secondary The relative number of painfree patients The relative number of painfree patients that experience a change of acute throat pain (pain reduction) on a visual analog scale (VAS) ranging from 0 millimeters (no pain) to 100 millimeters (most severe pain) of lower than 10 (<10) at day 1,2,3,4 compared to baseline 4 days
Secondary The average time taken to symptom resolution1 The time taken to symptom resolution reaching a Tonsillopharyngitis Score (TSS) of less than 3 (<3). The TSS score consists the following four symptoms: throat pain, difficulty in swallowing, salivation, reddening and fever (fever was defined as >38.5°C for this score) which are all rated on a scale with 0=none, 1=mild, 2=moderate, 3=severe. 4 days
Secondary The average time to symptom resolution2 The average time required for subjective symptom resolution 4 days
Secondary The rate and kind of concomitant medication use The rate of use and kind of concomitant medication that are used by patients are recorded by questionaire as part of the patient diary and analyzed in descriptive manner 4 days
Secondary The throat status as assessed by the investigating physician Throat status (reddening, swelling, inflammation) assessed by physician. Assessed are: The presence of reddening in the throat (yes/no) and swelling (light, moderate, severe) and reddening, swelling, and coating of the tonsils (yes/no). beginning vs. after 90 minutes of treatment vs. 4 days of treatment. 4 days
Secondary Rate of "good" and "very good" efficacy ratings vs. "moderate" and "bad" efficacy ratings as assessment by a 1) physician 2) the patient Global subjective assessment of the subjective efficacy after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 rated 1) by physician and 2) by the patient with "very good", "good", "moderate", "bad" 4 days
Secondary Rate of treatment acceptance (yes) by the patient The rate of treatment acceptance assessed by asking patients if they would retake the IMP (yes) or refuse (no) at final visit 2. 4 days
Secondary The rate and kind of occuring adverse events The rate and kind of occuring adverse events assessed at visit 2 and analyzed in descriptive manner 4 days
Secondary Rate of "good" and "very good" tolerability ratings vs. "moderate" and "bad" efficacy ratings as assessment by the patient Global subjective assessment of the subjective tolerability after acute intake of 90 minutes at visit 1 and after 4 days of continous intake at final visit 2 rated by the patient with "very good", "good", "moderate", "bad" 4 days
Secondary Rate and kind of clinically relevant changes in vital parameters as assed by physical examination by the investigating physician Rate and kind of clinically relevant changes in vital parameters (pulse, both blood pressure, body temperature) derived from exhamination by investigating physician at inclusion visit 1 and at final visit 2 4 days
