Filter by:The purpose of this study is to assess the safety and efficacy of Lu AA21004 in participants with major depressive disorder after completion of an 8-week double-blind treatment period in a preceding study (Lu AA21004/CCT-003; NCT01355081).
This study involves collaboration between McLean Hospital, Geriatric Medicine at the Cambridge Health Alliance (CHA) and other sites within the Partners and Harvard Medical School network. The investigators plan to recruit individuals 55 to 89 years old with treatment resistant depression. Someone with "treatment resistant" depression for this study may be someone who still has sad or low feelings and thoughts even though he/she is taking an antidepressant medication for at least 8 weeks to help relieve his/her depression. During the study, subjects will gradually add memantine hydrochloride in dosages up to 20 mg/day for 8 weeks to their standard antidepressant treatment. The investigators are doing this research study to help answer 3 questions: 1. Do older adults with treatment resistant Major Depression have lower levels of a chemical in the brain called NAAG than older adults without Major Depression? 2. Do older adults with naturally low NAAG levels do better on memantine hydrochloride treatment than older adults with higher amounts of this chemical on memantine hydrochloride treatment? 3. Do older adults with treatment resistant depression have more problems with memory and concentration than older adults without depression? The investigators are also interested in looking at electrical and neuronal activity of the brain, spiritual beliefs, and fatigue in relationship to depression. The investigators hypothesize that: 1. Older individuals with treatment resistant Major Depression will have lower levels of NAAG compared with age-matched older control subjects. 2. Older adults with treatment resistant depression and low NAAG levels will do better on treatment with memantine hydrochloride than older adults on memantine with higher NAAG levels. 3. Older adults with depression will do better on tests of attention and executive functioning after treatment with memantine hydrochloride. 4. Healthy controls will do better on tests of attention and executive functioning than older adults with depression.
This study will evaluate the effect of food on LY2216684. There will be 2 study periods each lasting up to 5 days. There will be at least 7 days between the two doses and a follow up will occur at least 7 days after the last dose. Screening is required within 30 days prior to the start of the study.
The study involves a single oral dose of 18 mg (2 x 9mg tablets) LY2216684 taken on 2 occasions, once with activated charcoal and once without activated charcoal. The study will evaluate the effect of charcoal on the absorption of LY2216684. Side effects will be documented. There will be 2 study periods each lasting up to 5 days. There will be at least 7 days between the two doses and a follow up will occur at least 7 days after the last dose. Screening is required within 30 days prior to the start of the study.
The aim of this study is to determine whether blood levels of lithium or sertraline are affected by different phases of the menstrual cycle and whether there is an effect on psychiatric symptoms. Subjects are seen for two visits: one visit during the luteal phase and one visit during the follicular phase of the menstrual cycle. On each visit, they will fill out a depression, anxiety and mania rating scale. Also at each visit a 20mL blood sample will be drawn to measure progesterone level and either a lithium or sertraline level, depending on which medication the patient takes. The primary hypothesis in this study is that blood levels of lithium and sertraline will be significantly lower in women during the luteal phase of the menstrual cycle than during the follicular phase. Examination will also be made of whether symptoms will increase in severity during the luteal phase as compared to the follicular phase. The investigators expect a negative linear association between symptom severity and blood level, i.e. expect symptom severity to worsen as blood levels of lithium or sertraline decrease.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel, multiple dose study designed to evaluate the safety and tolerability of the co-formulation of ALKS 33 with buprenorphine (ALKS 5461) in subjects with Major Depressive Disorder (MDD) who are inadequately/partially responding to current treatment with a stable dose of a serotonin-selective reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI).
This is a multiple-dose study to assess the safety and pharmacology of ABT-436 in physically healthy subjects with mild to moderate depressive symptoms who are not taking any antidepressant medication. Efficacy for treatment of depressive symptoms is not a goal of this study.
This study will evaluate the pharmacodynamic and pharmacokinetic interaction of LY2216684 with alcohol in healthy participants. This study will run approximately for 34 days.
'Real life' retrospective patient cases (10) to provide an objective and robust analytical report of patient management and prescriptions behaviours for Schizophrenia, Bipolar disorders and Major depressive disorders.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of Levomilnacipran ER compared to placebo in patients with Major Depressive Disorder (MDD).
