Plain English summary of protocol

Background and study aims
Dalumin is an extract of a plant herb called Filipendula ulmaria. In studies with healthy people Dalumin was safe in doses up to 2400 mg. The aim of the study is to find out how effective Dalumin is at treating patients with somatoform disorders, a disease with physical symptoms that cannot be explained by a medical condition.

Who can participate?
Adult men and women with somatoform disorders

What does the study involve?
Participants are randomly allocated to one of two groups. One group receives Dalumin for 10 weeks. The other group takes a placebo (dummy) instead. The severity of the symptoms of the disease are measured after 1, 2, 4, 7 and 10 weeks of treatment.

What are the possible benefits and risks of participating?
Participants who receive Dalumin could experience an improvement of their somatoform symptoms. There is no evidence available from the current information about any risks involved.

Where is the study run from?
About 40 selected centres (medical practices) in Germany

When is the study starting and how long is it expected to run for?
June 2014 to June 2016

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

Scientific titleMulti-center, double-blind, placebo-controlled, randomized phase II study to assess the efficacy, safety and tolerability of Dalumin (WS® 1090) in patients with somatoform disorders
Study objectivesThe objective of the study is to assess the efficacy of Dalumin in the treatment of patients with somatization disorder in comparing the change of the Hamilton Anxiety Scale total subscore somatic anxiety or the change of Somatic Symptom Inventory subset pain between baseline and Week 10 between Dalumin and placebo.
Ethics approval(s)Ethics Committee at the Medical Faculty of the University of Würzburg (Ethikkommission bei der Medizinischen Fakultät der Universität Würzburg), 08/05/2014, ref. 58/14_ff
Health condition(s) or problem(s) studiedSomatization disorder (ICD 10, F45.0); Undifferentiated somatoform disorder (ICD 10, F45.1); Pain disorder (ICD 10, F45.4)
InterventionThe patients take two tablets (daily dose: placebo or Dalumin 600 mg or Dalumin 1200 mg) in the morning orally for 70 days. Randomization is carried out by a member of the sponsor who is not directly involved in the study conduct. The investigators receive numbered study medication in blocks of six. If a patient is to be randomised, he/she receives the drugs with the lowest available drug number.
Intervention typeDrug
Pharmaceutical study type(s)
PhasePhase II
Drug / device / biological / vaccine name(s)Dalumin
Primary outcome measure1. The individual difference of the total score of the Hamilton Rating Scale for Anxiety, somatic subscore (HAMAsom) between baseline and end of treatment (Week 10 or end of treatment in case of premature study termination)
2. Individual difference of the total score of the Somatic Symptom Inventory subset pain (SSIsp) between baseline and end of treatment (Week 10 or end of treatment in case of premature study termination) comparing Dalumin and placebo
Secondary outcome measures1. Response criteria based on the HAMAsom total and on the SSIsp total score
2. Difference of the total score of the Montgomery-Asberg Depression Rating Scale (MADRS) between baseline and end of treatment. Response criteria based on the MADRS total score
3. Individual difference of single items of the HAMAsom, single items of the MADRS, total score and single items of the SSIsp; total score and subscales of the Sheehan Disability
4. Clinical Global Impressions of severity of disorder (CGI - item 1): Clinical Global Impressions of change from baseline (CGI - item 2)
5. Visual Analogue Scale overall pain (VASop)
6. Symptom Checklist 90 (SCL 90)
7. Frequency of patients who discontinue the study prematurely due to inefficacy
8. Adverse events, Laboratory data, ECG, vital signs
Overall study start date30/06/2014
Completion date30/06/2016
