Beta-Agonist Versus OnabotulinumtoxinA Trial for Urgency Urinary Incontinence
Women and Infants Hospital of Rhode Island
Urgency Urinary Incontinence
The goal of this clinical trial is to compare treatment outcomes between an oral
medication (beta agonist) versus onabotulinumtoxinA injections in women with urgency
urinary incontinence (UUI).

The goal of this clinical trial is to compare treatment outcomes between an oral medication (beta agonist) versus onabotulinumtoxinA injections in women with urgency urinary incontinence (UUI). Participants will be randomly selected to receive one of the two treatments. The primary outcome measure will be at 3 months, and women will be followed for a total of 12 months. Based on patient expert input, there are 2 primary outcomes: Treatment satisfaction and urinary symptom severity. Type: Interventional Start Date: Jun 2023 |
Immunization With BCG Vaccine to Prevent Tuberculosis Infection
Henry M. Jackson Foundation for the Advancement of Military Medicine
Tuberculosis Infection
The purpose of this research is to find out if a single dose of pre-travel vaccination
with BCG can lessen tuberculosis (TB) infection by producing an immune response when
given to adults traveling to countries with a high burden of TB. BCG will be compared
with a placebo (an inactive vaccine). BCG... expand
The purpose of this research is to find out if a single dose of pre-travel vaccination with BCG can lessen tuberculosis (TB) infection by producing an immune response when given to adults traveling to countries with a high burden of TB. BCG will be compared with a placebo (an inactive vaccine). BCG (Japan) is used globally but is not approved for use in the United States, therefore it is considered experimental. Participants choosing to take part in this research study, will be randomly assigned (this is like a coin flip) to BCG or placebo. 2000 eligible volunteers will be enrolled.

Metformin in Alzheimer's Dementia Prevention
Columbia University
Mild Cognitive Impairment
MAP will be a multisite phase II/III 1:1 randomized controlled trial (RCT) of long acting
metformin (reduced mass Glucophage XR) vs. matching placebo in 326 men and women with
early and late aMCI, without diabetes, not treated with metformin, overweight or obese,
aged 55 years to 90 years. The RCT... expand
MAP will be a multisite phase II/III 1:1 randomized controlled trial (RCT) of long acting metformin (reduced mass Glucophage XR) vs. matching placebo in 326 men and women with early and late aMCI, without diabetes, not treated with metformin, overweight or obese, aged 55 years to 90 years. The RCT will last 18 months and have 4 visits: baseline, 6-months, 12-months, and 18-months. The RCT will be preceded by a screening phase followed by randomization and a titration period in which drug/placebo will be titrated from 500 mg a day (one tablet) to 2,000 mg a day (4 tablets), in increments of 500 mg (one tablet) every 10 days. Participants will remain in the RCT on the tolerated dose, and included in analyses on an intent to treat basis. We expect the attrition rate to be 10%/year. Neuropsychological battery, clinical interviews, physical exam, and phlebotomy will be conducted at baseline and every 6 months. Brain MRI will be conducted in approximately half of the participants (186) twice, at baseline, and after the last study visit at month 18. We will also conduct brain amyloid Positron Emission Tomography (PET) using 18F-Florbetaben, and tau PET using 18F-MK6240 in half of the participants at baseline and end of the RCT. The primary clinical outcome of the study will be changes in the Free and Cued Selective Reminding Test. The secondary endpoints are 1) changes in global cognitive performance, measured with the Alzheimer's Disease Cooperative Study Preclinical Alzheimer Cognitive Composite (ADCS-PACC); 2) changes in neurodegeneration, ascertained as cortical thickness in areas affected by AD on brain MRI; 3) changes in cerebrovascular disease, ascertained as white matter hyperintensities (WMH) volume on brain MRI; 4) Changes in whole brain amyloid ß (Aß) SUVR and in incident amyloid positivity; 5) Changes in tau SUVR in a composite brain region comprising medial and inferolateral temporal cortex; 6) Changes in plasma AD biomarkers. The data coordinating center and Imaging Core is located at John Hopkins University. The PET coordinating center is located at UC-Berkeley. The Clinical Coordinating and Monitoring Center and the central laboratory will be located at Columbia. The Research pharmacy function will be shared by the University of Rochester, which will dispense randomization kits, and the University of Iowa, which will receive bulk metformin and identical matching placebo from EMD Serono.

AHEAD 3-45 Study: A Study to Evaluate Efficacy and Safety of Treatment With Lecanemab in Participants...
Eisai Inc.
Preclinical Alzheimer's Disease
Early Preclinical Alzheimer's Disease
The primary purpose of this study is to determine whether treatment with lecanemab is
superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive
Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether

The primary purpose of this study is to determine whether treatment with lecanemab is superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether treatment with lecanemab is superior to placebo in reducing brain amyloid accumulation as measured by amyloid positron emission tomography (PET) at 216 weeks of treatment (A3 Trial). This study will also evaluate the long-term safety and tolerability of lecanemab in participants enrolled in the Extension Phase. Type: Interventional Start Date: Jul 2020 |
