Efficacy of LoDoCo in Improving Exercise Capacity Among Patients With HFpEF and Inflammation
The purpose of this research study is to determine the effectiveness of low dose colchicine (LoDoCo) on measures of exercise capacity, physical function, frailty, and quality of life, among patients with heart failure with chronic stable preserved ejection fraction (HFpEF) and systemic inflammation. The use of LoDoCo in this study is considered investigational as it has not been approved by the Food and Drug Administration (FDA) for the treatment of exercise capacity in patients with HFpEF. Participants will undergo a 1-day screening that includes a blood draw and physical examination. If deemed eligible for the study, participants will undergo a baseline visit within 2 weeks of screening visit that includes physical examination, exercise testing, echocardiography and completion of quality-of-life surveys. Participants will also be randomized at this visit (randomly assigned to a group) to receive either LoDoCo or placebo (inactive substance) for 3 months. Participants will be called back at 3 months for repeat physical examination, blood draws, echocardiography, exercise testing and completion of quality-of-life surveys. Each visit will take about 3 hours. Total study duration is about 3 months.

A Research Study to Look at How Ziltivekimab Works Compared to Placebo in People With Heart Failure and Inflammation (HERMES)
This study will be done to see if ziltivekimab can be used to treat people living with heart failure and inflammation. Participants will either get ziltivekimab or placebo. Participants will get study medicine for once-monthly injections either in a pre-filled syringe to inject the study medicine into a skinfold or a pen-injector to inject the study medicine into flat skin. The study is expected to last for up to 4 years. Participants will have up to 20 clinic visits. Participants will have to use a study app on their phone to record and share information about all their injections of study medicine and to fill in questionnaires.

Alzheimer's Disease Neuroimaging Initiative 4 (ADNI4)
Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) Study has been to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI4 continues the previously funded ADNI1, ADNI-GO, ADNI2, and ADNI3 studies that have combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of AD.

Cognitive Outcomes of Brain Stimulation As a Later-in-Life Treatment (COBALT)
This is a pilot study being done to attempt to improve episodic memory problems in persons with mild cognitive impairment (MCI) or dementia. The pre-supplemental motor area (preSMA) and dorsal anterior cingulate cortex (dACC) have been shown to play a role in episodic memory and language retrieval. Prior studies have suggested that neurostimulation targeting this region can improve episodic memory and word recall. The purpose of this study is to examine the efficacy of high-definition transcranial direct current stimulation (HD-tDCS) to the preSMA/dACC region and its influence on word retrieval and other cognitive functions in patients with MCI or dementia. Entraining the preSMA/dACC circuit with 10 sessions of HD-tDCS will allow us to study whether neurostimulation may be an effective treatment.

Modulation of SERCA2a of Intra-myocytic Calcium Trafficking in Heart Failure With Reduced Ejection Fraction (MUSIC-HFrEF1)
It is believed that targeted SERCA2a enzyme replacement in HFrEF patients will correct defective intracellular Ca2+ hemostasis, resulting in improved cardiac contractile function and energetics which will, in turn, translate to improved clinical outcomes. Additionally, it is hypothesized that correcting SERCA2a dysfunction will also improve coronary blood flow through correction of the impaired endothelium-dependent nitric oxide-mediated vasodilatation observed in heart failure.

Polypill Strategy for Heart Failure With Reduced Ejection Fraction
Heart failure with a reduced ejection fraction (HFrEF) represents a significant public health burden in the United States, with a growing prevalence particularly among African Americans and Hispanic Americans and individuals of low socioeconomic status (SES). Although effective therapies exist, gaps in their uptake contribute substantially to the excess burden of heart failure. The "polypill" is an inexpensive once daily pill containing three agents proven to improve morbidity and mortality in heart failure and represents potential strategy for increasing the utilization of proven HF therapies. The proposed study is a pragmatic, single-center, randomized trial to test the feasibility and effectiveness of a polypill-based strategy for the treatment of HFrEF in a low-income, racially diverse population.
