• Status: Not yet recruiting
• Trial end date: 2023-08-01
• Target enrollment: 0
• Participant gender: All

Summary

This study will enroll participants who have been diagnosed with type 2 diabetes and are experiencing symptoms of depression. This study will look at an anti-depressant medication called vortioxetine (Trintellix). Vortioxetine is an oral medication (pill) that has been approved by the US Food and Drug Administration (FDA) to treat depression in adults.

The purpose of this study is to look at what effects (if any) vortioxetine may have on symptoms of depression in patients with type 2 diabetes. This study will also look at what effects (if any) vortioxetine has on blood sugar, and how vortioxetine may improve the way our brains are able to adapt and respond to stress.

• Women only: Must be post-menopausal at time of screening visit (i.e., defined by NO menstruation for at least the past 12-months).

• Diagnosis of T2D, as defined by a diagnosis of T2D (for at least 12 months) in the medical record made by a physician (i.e., denoted as 250.XX according to ICD-9/ICD-10 billing codes) OR

• current use of oral hypoglycemic medications or insulin OR

• having a fasting plasma glucose ≥126 mg/dL in the medical record OR

• having a 2-hour oral glucose tolerance test ≥200 mg/dL in the medical record

• Patients who meet criteria for current MDD without significant co-morbid psychiatric diagnoses, as determined by study PI from screening visit:

• Clinical Psychiatric Interview to determine DSM-V criteria for current MDD AND

• A minimum score of 18 on the Hamilton Depression Scale (HAM-D)

• Patients with T2D and current MDD that would benefit from antidepressant therapy, which may include:

• Patients with current MDD who were NOT prescribed an antidepressant medication in the past;

• Patients with current MDD who are NOT responding to their current prescribed antidepressant;

• Patients with current MDD who are experiencing breakthrough depressive symptoms despite being maintained on another antidepressant.

• Must have the ability to provide informed consent to participate in the study.

Exclusion Criteria:

Exclusion Criteria to Reduce False Positive Rates of Inflammation

• Specific pre-existing chronic pain conditions such as rheumatoid arthritis or fibromyalgia. However, this will NOT include more localized pain-related conditions such as low-back pain or complications associated with T2D (e.g., diabetic neuropathy).

• Current acute infection/infectious disease (i.e., a cold or the flu). Based on the clinical judgement of the study PI, a risk assessment will be conducted if a participant endorses some acute infection/infectious disease, but would be otherwise suitable to enroll in the study following a brief wait period for full symptom remission.

• Pre- and peri-menopausal women (i.e., defined as the presence of ANY menstruation within the past 12 months).
