A Study to Test How Well Different Doses of BI 1569912 Are Tolerated and How Well They Work in People With Depression Who Take Anti-depressive Medication

Completed · Phase 1 · Has a placebo group

Conditions studied: Depressive Disorder, Major

In brief

This study is open to adults between 18 and 65 years of age who have depression (major depressive disorder). People with a current depressive episode lasting between 2 months and one and a half years can join the study. This study is for people for whom existing treatments for depression do not work sufficiently. The purpose of this study is to test how well a medicine called BI 1569912 is tolerated and whether it may help people with depression. It is planned to test 4 different dosages of BI 1569912 in this study. Each participant gets either one BI 1569912 dosage or placebo. It is decided randomly, which means by chance, who gets which treatment. Participants take BI 1569912 or placebo as tablets once during the study. Placebo tablets look like BI 1569912 tablets but do not contain any medicine. Participants also continue taking their usual medicine for depression throughout the study. Participants are in the study for about 5 weeks. During this time, they visit the study site 4 times, with a stay at the study site for 9 days. The doctors check the health of the participants and note any health problems that could have been caused by BI 1569912. The participants fill in questionnaires about their depression symptoms.

At least moderate severity of MDD confirmed by a trained site-based rater, at screening and Visit 2 day 1 (i.e. prior to randomisation). For patients who are not on an SSRI at Visit 1, MDD must be confirmed additionally at Visit 1 A.
In the current episode, patients have shown insufficient treatment response (defined by less than 50 % response to one or more antidepressant drugs of adequate dose and treatment duration (according to Summary of Product Characteristics) as evaluated by Antidepressant Treatment Response Questionnaire (ATRQ). Participants, who, in addition to their monotherapy with an SSRI/SNRI, are taking additional low dose antidepressant medications for purposes other than treating depressive symptoms, are not excluded. The dose must be less than the lowest dose indicated for MDD. Use of bupropion is not allowed.
Documented ongoing monotherapy treatment of ≥ 6 weeks at randomisation (i.e. Visit 2 day 1) with a protocol specified Selective Serotonin Reuptake Inhibitors (SSRI) or Serotonin-Norepinephrine Reuptake Inhibitors (SNRI) at adequate dose (according to ATRQ assessment). sampling at Visit 1). Patients who are not on an SSRI at Visit 1 will undergo a lead in phase as described in the Flow Chart. Patients who meet all the eligibility criteria but are not on an SSRI/SNRI at Visit 1, will have the option to undergo a 6 week open label lead in phase with SSRI/SNRI. These patients will be reassessed at Visit 1A to determine eligibility to be randomized to the trial.
Male or female patients, aged 18 to 65 years at screening. If Women of childbearing potential (WOCBP) are included, they have to be able and willing to use two methods of contraception which include one highly effective method of birth control per ICH M3 (R2) that result in a low failure rate of less than 1 %, plus one additional barrier method. If men who are able to father a child, are willing to participate, they have to use an adequate form of effective contraception for the duration of study participation and for at least 28 days after treatment has ended.
Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial. Please note complete sexual abstinence is allowed when this is in line with the preferred and usual lifestyle of the patient (note: periodic abstinence such as calendar, ovulation, symptothermal, post-ovulation methods and withdrawal are not acceptable methods of contraception) - (in this specific case the barrier methods, as mentioned below, are not applicable).
