Brief Summary
The researchers in this trial want to learn more about the drug Laif® 900 in preventing the return of signs and symptoms of depressions (also called relapse) in patients suffering from moderate depression episodes. The study drug Laif® 900 is based on Hypericumextract made from the plant St. John wort. Patients will be accepted to take part in the study if they have 20-24 points on the Hamilton Depression Rating Scale (HAM-D) which is a questionnaire helping the doctor to rate the severity of the depression and includes questions on patient's mood, sleep difficulties, agitation, anxiety and weight loss. About 400 patients will be enrolled into the first part of the study and will be treated for 12 weeks with Laif® 900 capsule once daily. Only patients with an improved HAM-D score by 50% will stay in the study and continue with the second part of the study which will last for 24 weeks. In this second part of the study patients will receive either Laif® 900 capsule once daily or an inactive tablet (placebo). Neither the treating doctor nor the patient will know which patient receives the Laif® 900 or placebo. At the end of the study the researcher will assess the effectiveness of the study drug in prevention relapse of depression episodes and will also have more information on the safety of the study drug.
