The efficacy of single agent liposomal doxorubicin as compared to single agent docetaxel will be evaluated as first line treatment in metastatic breast cancer patients, with subsequent crossover to the opposite arm at disease progression or patient intolerance. We will explore this as well as any possible cross resistance between these two agents.
NCT01751828
The long-term goal is to determine if decreased blood flow to the brain (cerebral hypoperfusion) is predictive of antidepressant outcomes in late-life depression (LLD). Studies in younger adult report that successful antidepressant treatment is associated with increases in cerebral blood flow, with no change in blood flow being observed in nonresponders. Thus cerebral hypoperfusion may be a biomarker of poor response to antidepressants. In LLD, this may occur secondarily to underlying vascular disease. If LLD is characterized by cerebral hypoperfusion and it does have predictive power to identify individuals who will poorly respond to conventional antidepressants, this would support the study of interventions that improve cerebral perfusion and may improve antidepressant outcomes. As an initial step in this research, this pilot study will utilize MRI to examine if resting blood flow deficits predict and persist with antidepressant nonremission in an elderly population. The rationale for this proposal is that it will guide the design and power requirements of a larger, definitive trial examining the relationship between cerebral perfusion and depression outcomes. Importantly, support for this mechanism being linked to LLD would also support studies examining the antidepressant efficacy of drugs that may improve cerebral perfusion. The primary purpose of this pilot study is a) to demonstrate feasibility by recruiting, scanning, and treating depressed elders; and b) to acquire preliminary data for competitive grant submissions. SPECIFIC AIM: To use MRI to test for differences in cerebral perfusion between individuals who do and do not remit to a 8-week course of sertraline.
