Plain English summary of protocol

Background and study aims
Dulamin is an alcoholic extract of Filipendula ulmaria. The objective of the study is to obtain information on the safety, tolerability, and pharmacokinetics of repeated oral doses of Dulamin in healthy subjects as well as information on the bioavailability and effects of food on pharmacokinetics.

Who can participate?
Adult healthy Caucasian males and females (aged 18 – 45 years) can participate in the study.

What does the study involve?
One group of the patients will receive Dulamin once and for 15 days in two cohorts of 1200 mg daily dose and 2400 mg daily dose. Safety assessments are performed during the whole study and blood sampling will be made at the specified time points after the first dose and after the last dose of Dulamin for 48 hours.
In another group, single doses of 1200 mg Dulamin will be investigated on three occasions: once as tablets with no meal, once as drinking suspension with no meal, once as tablets after administration of a meal.

What are the possible benefits and risks of participating?
The participants are healthy people and there will be no direct benefits in participating.
Filipendula ulmaria is a traditional herbal medicine in Europe. According to the ‘German monograph’, treatment with Filipendula ulmaria holds no risk of adverse drug reactions.

Where is the study run from?
The study will be performed in a specialised phase 1 unit in Germany.

When is the study starting and how long is it expected to run for?
The study will start in February 2013 and will run for about 6 months.

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

Scientific titleA phase I study to assess the safety and tolerability of repeated oral doses of 1200 mg and 2400 mg Dulamin once daily for 2 weeks in healthy volunteers as well as to evaluate the relative bioavailability of film-coated tablets containing 1200 mg Dulamin and to evaluate effects of food on its pharmacokinetics
Study objectivesThe aim of this study is to evaluate the safety and tolerability of repeated oral doses of 1200 and 2400 mg Dulamin in healthy subjects as well as to evaluate the bioavailability and the effect of food on pharmacokinetics.
