NCT03385512
This large scale multi-center cluster randomized controlled trial (RCT) is designed to assess the comparative effectiveness of three interventions in diverse ambulatory care settings and patient populations. Findings will help healthcare systems decide which approach to adopt to empower patients and enable providers to engage in patient centered communication. The specific aims are to: 1. Engage with patients and healthcare providers who have used the tools in the pilot study (ClinicalTrials.gov Identifier NCT02522286) at the Sutter Health Palo Alto Medical Foundation (PAMF), as well as new stakeholders at University of California San Diego Health System and Meyers Primary Care Institute at University of Massachusetts and Reliant Medical Group, to further refine and adapt these patient-centered interventions to be integrated into real world primary care clinics. 2. Conduct a large scale cluster RCT with three arms, to evaluate the comparative effectiveness of three interventions: OPEN with in-person SPI training (High Touch), OPEN with online SPI training (High Tech), and ASK. Primary outcomes will include patient perceptions of how well their PCPs have engaged them in patient centered communication. The investigators will also measure patients' confidence in managing their health, intention to follow through with care plans, and downstream behaviors in following through with care plans, use of services such as phone calls, secure messaging, and additional visits. 3. Identify the strategy that has the most potential for sustained impact and replication within and across healthcare systems. The investigators will analyze the fidelity to the intervention protocols, including consistency of delivery as intended and the time/effort involved in implementing the interventions. The investigators will also assess the extent to which the programs become institutionalized. The investigators anticipate that this multi-level healthcare system intervention will result in significant improvement in: patient satisfaction with how PCP has engaged them in the visit, confidence in selfcare; patients' intention to adhere to care plan, and clinical indicators. Furthermore, more effective communication would lower health service utilization after the visit. The investigators further expect that the intervention will affect physicians', medical assistants' and nurses' experience as well as healthcare system leaders' intention to implement in routine practice.
NCT03352557
The primary objective of the placebo-controlled period is to evaluate the safety and tolerability of BIIB092 in participants with mild cognitive impairment (MCI) due to Alzheimer's disease (AD) or with mild AD. The secondary objectives of the placebo-controlled period are to evaluate the efficacy of multiple doses of BIIB092 in slowing cognitive and functional impairment in participants with MCI due to AD or with mild AD, and to evaluate the immunogenicity of BIIB092 after multiple doses in participants with MCI due to AD or with mild AD. The primary objective of the long-term extension period is to evaluate the long-term safety and tolerability of BIIB092 in participants with MCI due to AD or with mild AD.
NCT04880577
As the in vivo reservoir of the Epstein-Barr virus, B cells play an important role in the perpetuation of MS disease activity. B cell depletion therapy with medications like ocrelizumab or rituximab have proved very successful in preventing clinical relapses and MRI activity in MS, but incomplete in terms of neuroprotection and symptomatic outcomes. Ocrelizumab and rituximab only target naïve and memory B cells expressing the CD20 marker but do not deplete the wide spectrum of B cell lineages including plasmablasts and plasma cells, which are also key reservoirs for EBV. This is particularly relevant to the mechanism of action of TAF, since EBV lytic reactivation occurs in coordination with B-cell differentiation. In vivo, the initiation of plasma cell differentiation provides the physiological trigger for EBV lytic reactivation, and EBV utilizes the plasma cell differentiation program to replicate. As these cells are ineffectively depleted by anti-CD20 treatment, the use of TAF would be highly complementary as an add-on treatment to anti-CD20 therapy. Anti-EBV therapy with TAF in combination with ocrelizumab or rituximab will therefore provide a synergistic approach to cover the whole EBV reservoir. The primary aims of the proposed trial are to determine if TAF, at the standard dose of 25 mg/day administered for 12 months: i) is safe and well-tolerated by individuals with RRMS over a period of treatment of 12 months; ii) leads to an overall improvement in fatigue, as assessed by the Modified Fatigue Impact Scale by 12 months; and iii) causes a reduction in serum concentrations of neurofilament light chain (NfL), a marker of neuronal damage in MS.

NCT02649439
Background: Some people who have been treated for prostate cancer still have high prostate-specific antigen (PSA) levels. This may indicate cancer. These people have non-metastatic castration sensitive prostate cancer (nmCSPC) or biochemical recurrent prostate cancer. Researchers think the immune system can be taught to fight and kill cancer cells. They think an immunotherapy vaccine called prostvac could help reduce PSA levels in people with this type of prostate cancer. Objective: To test if prostvac can decrease tumor growth rate as measured by PSA compared to getting surveillance alone. Eligibility: Men ages 18 or older who have nmCSPC or biochemical recurrent prostate cancer Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Bone scan Computed tomography (CT) scan, or magnetic resonance imaging (MRI) and positron emission tomography (PET) scan: They lie in a machine that takes pictures of the body. Electrocardiogram: Soft electrodes are stuck to the skin to record heart signals. Participants will be part of 1 of 2 arms: Arm A will get prostvac for 6 months. Arm B will have surveillance for 6 months followed by prostvac for 6 months. During the prostvac period, participants will get prostvac as a shot under the skin on weeks 1, 3, and 5, and then monthly for a total of 5 months. Participants will have follow-up visits at least every month until they recover from prostvac side effects or their cancer worsens. Visits may include repeats of screening tests. Participants will be followed for up to 15 years. They will have a physical exam every year for the first 5 years. They will have phone calls once a year.

NCT03674541
Myalgic encephalomyelitis/Chronic fatigue syndrome (ME/CFS), otherwise known as Chronic fatigue syndrome (CFS) or myalgic encephalomyelitis (ME), is an under-recognized disorder whose cause is not yet understood. Suggested theories behind the pathophysiology of this condition include autoimmune causes, an inciting viral illness, and a dysfunctional autonomic nervous system caused by a small fiber polyneuropathy. Symptoms include fatigue, cognitive impairments, gastrointestinal changes, exertional dyspnea, and post-exertional malaise. The latter two symptoms are caused in part by abnormal cardiopulmonary hemodynamics during exercise thought to be due to a small fiber polyneuropathy. This manifests as low biventricular filling pressures throughout exercise seen in patients undergoing an invasive cardiopulmonary exercise test (iCPET) along with small nerve fiber atrophy seen on skin biopsy. After diagnosis, patients are often treated with pyridostigmine (off-label use of this medication) to enhance cholinergic stimulation of norepinephrine release at the post-ganglionic synapse. This is thought to improve venoconstriction at the site of exercising muscles, leading to improved return of blood to the heart and increasing filling of the heart to more appropriate levels during peak exercise. Retrospective studies have shown that noninvasive measurements of exercise capacity, such as oxygen uptake, end-tidal carbon dioxide, and ventilatory efficiency, improve after treatment with pyridostigmine. To date, there are no studies that assess invasive hemodynamics after pyridostigmine administration. It is estimated that four million people suffer from ME/CFS worldwide, a number that is thought to be a gross underestimate of disease prevalence. However, despite its potential for debilitating symptoms, loss of productivity, and worldwide burden, the pathophysiology behind ME/CFS remains unknown and its treatment unclear. By evaluating the exercise response to cholinergic stimulation, this study will shed further light on the link between the autonomic nervous system and cardiopulmonary hemodynamics, potentially leading to new therapeutic targets.
