| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The primary objectives are to demonstrate superiority of Octenidine lozenges compared with placebo in terms of rate of responders, and to demonstrate non-inferiority of Octenidine lozenges compared with active comparator (neo angin®) in terms of the rate of responders. Response is defined as a score of 4 or 5 on the Pain Relief Rating Scale (PRRS) (patient assessment) at visit 3 (study day 3 or 4, LOCF) and a total score of 0 or 1 on the Tonsillo-Pharyngitis Score (TPS) (investigator assessment) at visit 3 (study day 3 or 4, LOCF).
 Both primary objectives are efficacy objectives
 
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| Secondary efficacy objective is to compare Octenidine, matching placebo and active comparator in terms of: -Pain Relief Rating Scale (PRRS): rate of patients with pain relief at visits 2 and 3 and at study day 2
 -Tonsillo-Pharyngitis Score (TPS): rate of patients with improvement at visit 2 and visit 3
 -Tonsillo-Pharyngitis Score (TPS): mean change from baseline at visit 2 and visit 3
 - Visual Analogue Scales (VAS): mean change from baseline at visit 2 and visit 3
 
 The other secondary  (safety)
 objective is to compare Octenidine, matching placebo and active comparator in terms of
 - adverse events
 - local adverse reactions according to pre-specified list
 - results of the physical examination
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| -Age between 12 and 65 years, signed informed consent -Sore throat for a maximum of 36 hours, short-term adjuvant treatment indicated.
 -Inflammation of the mucosa of the mouth and throat with typical symptoms like pain, reddening and swelling, to be verified by the investigator by means of:
 - a physical examination
 - a Tonsillo-Pharyngitis Score >2
 -Pain on two 10 cm visual analogue scales (VAS) (pain at rest and pain when swallowing) at day 0 of at least 10 cm (sum of both VAS). At least 4 cm on each of both VAS.
 - On-site test for streptococcus negative
 |  | 
| E.4 | Principal exclusion criteria |

 - Allergy to Octenidine or ingredients of neo-angin® (Levomenthol, 2,4-Dichlorbenzylalcohol, Amylmethacresol, Peppermint Oil, Glucose or Sucrose)
 - Present gastrointestinal diseases or gastrointestinal diseases in the anamnesis which may be regarded as pre-disposition for adverse effects of orally administered antiseptics, e.g. gastrointestinal diseases associated with diarrhoeas and/or imbalances of the microbiological colonisation of the gastrointestinal tract
 - Diabetes, malignomas, severe infections like hepatitis A, B, C, HIV, tuberculosis
 - Other diagnoses that could interfere with the study diagnosis or therapy
 - Immunosuppressive therapy within 2 months prior to study start or during study
 - Addiction to alcohol or drugs
 - Pregnancy or lactation
 - Participation in a further clinical trial at the same time or within the last 4 weeks prior to inclusion into the present study.
 All exclusion criteria referring to clinical aspects are to be verified by the investigator during a physical examination.
