Active and Placebo Controlled Study to Test the Efficacy and Safety of an Aspirin-Lidocaine Lozenge in the Symptomatic Treatment of Sore Throat Associated With a Common Cold

This study has been completed.

History: No changes posted
The purpose of this study is to investigate the analgesic efficacy of a single dose of a fixed combination of 500 mg Aspirin (Acetylsalicylic Acid) and 4 mg Lidocaine in adult patients with sore throat associated with a common cold in comparison to a single treatment with 500 mg Aspirin or 4 mg Lidocaine alone as well a Placebo (treatment without any active ingredient). The combination of Aspirin and Lidocaine in a single lozenge is expected to provide relief from sore throat pain by sequential action. A very fast inset of action will be achieved by the locally acting Lidocaine and a long duration of action will be achieved by the systemically acting Aspirin.

Condition Intervention Phase
Common Cold Pharyngitis Tonsillitis Drug: Acetylsalicylic acid (Aspirin, BAYE4465) & Lidocain Drug: Acetylsalicylic Acid (Aspirin, BAYE4465) Drug: Lidocain Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A 4-arm, Multicenter, Randomized, Double-blind, Placebo- and Active-controlled, Single Dose, Parallel Group Study Comparing Efficacy and Safety of a Fixed Combination of 500 mg Acetylsalicylic Acid + 4 mg Lidocaine With 500 mg Acetylsalicylic Acid and 4 mg Lidocaine Monotherapy as Well as Placebo in Adult Patients With Sore Throat Associated With a Common Cold.
