Placebo and Active Controlled, Double Dummy Study to Compare Efficacy of Aspirin and Ibuprofen in Treatment of Episodic Tension-type Headache

This study has been completed.
Information provided by (Responsible Party):
Bayer Identifier:
First received: May 17, 2011
Last updated: December 23, 2014
Last verified: December 2014
The purpose of this study is to determine the efficacy and tolerability of 500 mg and 1000 mg Aspirin® (study medication) by comparing it to placebo (the control group without active substance) or 200 mg or 400 mg Ibuprofen (study medication) in treating the symptoms of episodic tension-type headache. The study is designed to develop a treatment method against episodic tension-type headache which will have more advantages for patients than the methods that are currently available.

Condition Intervention Phase
Headache Tension-Type Headache Tension-Type Headache (Episodic) Drug: Acetylsalicylic acid (Aspirin, BAYE4465) Drug: Ibuprofen Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicentre Randomised Parallel-groups Double-blind Double-dummy Single-dose Study to Compare Acetylsalicylic Acid 500 mg and 1,000 mg With Ibuprofen 200 mg and 400 mg and Placebo for Tolerability and Efficacy in the Treatment of Episodic Tension-type Headache

Secondary Outcome Measures:
  • Headache pain relief measured serially on a categorical scale [ Time Frame: Until 4 hours post dose ]
  • Measuring the functional ability on conducting everydays activity on a 4 point categorical scale [ Time Frame: 2 and 24 hours post dose ]
  • Global assessment of pain therapy [ Time Frame: 24 hours post dose ]
  • Safety - assessment of adverse events [ Time Frame: Up to 10 weeks after screening ]
