Plain English Summary

Background and study aims
Acute respiratory illnesses are a common reason for seeking medical care. Apart from rhinitis, acute bronchitis is the most commonly diagnosed disease in pediatric practices. Acute bronchitis is characterized by the sudden onset of cough and production of sputum (a mixture of saliva and mucus) in a patient with no history of chronic pulmonary (lung) disease and no evidence of pneumonia or sinusitis. It is caused by a viral infection in the majority of cases. In Germany, EPs® 7630 solution and EPs® 7630 syrup are approved by the German Regulatory Authority for the indication acute bronchitis for the use by patients from the age of 1 year. The aim of this study is to evaluate the safety and tolerability of treatment with EPs® 7630 syrup in comparison to EPs® 7630 solution in patients between 1 and 5 years old suffering from acute bronchitis symptoms. During the study course the patients´ health status will also be assessed.

Who can participate?
Children aged between 1 and 5 years suffering from symptoms related to acute bronchitis that have started within 72 hours before inclusion into the study.

What does the study involve?
If you have agreed for your child to take part your child’s doctor will first diagnose whether your child is eligible for the study. Your child’s doctor will conduct a general physical examination, and measure height, weight and body temperature. He will carry out heart and respiratory rate measurements. The examination includes assessment of the severity of respiratory tract infection symptoms and general symptoms related to acute bronchitis. He also will collect a blood sample. If your child meets all criteria for inclusion your child will be randomly allocated to receive either EPs® 7630 solution or EPs® 7630 syrup. Your child’s doctor will tell you to which treatment group your child belongs. Throughout the 7-day treatment period, your child has to take the study medication orally three times a day. Seven days after the start of treatment you will attend a second visit and the examinations of the first visit will be repeated. You will also be asked about the change of your child’s health status and how satisfied you are with the treatment. As it is a safety study your child’s doctor also will ask you about any undesired effects your child was suffering from during the week on study medication.

What are the possible benefits and risks of participating?
EPs® 7630 may improve your child’s bronchitis symptoms. By participating in the study your child will help us to gain more data on the safety and tolerability of EPs® 7630 in children with acute bronchitis. Based on the very good tolerability and safety profile of EPs® 7630 solution and EPs® 7630 syrup in this age group as shown in previous studies, there is no major risk linked to the intake of EPs® 7630. Uncommon side-effects include stomach pain, heartburn, nausea or diarrhoea, and in rare cases there may be mild bleeding from the gums or nose, skin rash, nettle rash, or itching of the skin and mucous membranes. In very rare cases serious hypersensitivity reactions with swelling of the face, breathlessness and drop in blood pressure may occur. Pain and bruising may occur during blood sampling and there is a small risk of infection, but this can be reduced by the use of adequate techniques. The further examinations are not associated with any risk for your child.

Where is the study run from?
The study takes place in 40 centres (paediatric practices, general practices) in Germany.

When is the study starting and how long is it expected to run for?
The study ran from October 2011 until March 2013.

Who is funding the study?
Dr Willmar Schwabe GmbH & Co. KG (Germany).

Study information

Scientific title

Safety and tolerability of Pelargonium sidoides extract EPs® 7630 in children (1 to 5 years old) suffering from acute bronchitis: a randomised controlled trial


Study hypothesis

The primary aim of the study is to obtain information about the safety of a 7-day treatment with the EPs® 7630 syrup in comparison to the EPs® 7630 solution in children between 1 and 5 years of age suffering from acute respiratory tract infection symptoms related to acute bronchitis.
Since this study is a randomised open-label safety-study no hypotheses are formulated and the data will be analysed descriptively.
