The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
The main purpose of this study is to evaluate the effect repeated doses of AZD6765 (a drug being developed for the treatment of patients with severe major depressive disorder) has on the PK (pharmacokinetic) profile of Midazolam. (The PK profile is how the drug leaves your body and acts in the body.)

Condition Intervention Phase
Healthy Drug: AZD6765 Drug: midazolam Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: A Phase I Open-label, Fixed Sequence Study to Determine the Effect of Multiple Intravenous Doses of AZD6765 on the Pharmacokinetics of Oral Midazolam (CYP3A4 Substrate) in Healthy Subjects
