Clinical Trial to Evaluate the Safety and Immunogenicity of a Priming Regimen of 426c.Mod.Core-C4b Followed by HxB2.WT.Core-C4b Boosts, Both Adjuvanted With 3M-052 AF + Alum, in Adult Participants Without HIV and in Overall Good Health
NCT06796686
Recruiting
This is a partially randomized, open-label phase 1 study to evaluate the safety and immunogenicity of a priming regimen of 426c.Mod.Core-C4b adjuvanted with 3M-052 AF + Alum followed by boosts with HxB2.WT.Core-C4b adjuvanted with 3M-052 AF + Alum. The primary hypothesis is that the boosting with HxB2.WT.Core-C4b adjuvanted with 3M-052 AF + Alum will further mature broadly neutralizing antibody (bnAb)-precursor B-cell lineages elicited by 426c.Mod.Core-C4b adjuvanted with 3M-052 AF + Alum. 426...

Implementation and Interaction of Clinician And Patient-facing Tools Aiming to Intensify Neurohormonal Medicines for Heart Failure
NCT06526988
Recruiting
An increasing number of guideline-directed medical therapies (GDMT) have been developed for patients with chronic heart failure with reduced ejection fraction (HFrEF). When used in combination at recommended doses, patients often experience significant improvements in cardiac function, quality of life, and survival.1,2 However, GDMT underuse occurs for the vast majority of patients with HFrEF. Two recent trials demonstrated improved GDMT prescribing during a clinic visit, each using automated de... Read More

A Study on the Safety of TAK-279 and Whether it Can Reduce Inflammation in the Bowel of Participants With Moderately to Severely Active Ulcerative Colitis
NCT06254950
Recruiting
The main aim of this study is to learn if TAK-279 reduces bowel inflammation and symptoms compared to placebo. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate any problems. The participants will take capsules of either TAK-279 or placebo for up to 3 months (12 weeks). Then all the participants will receive TAK-279 for the rest of the treatment part of the study (1 year or 52 weeks). During the study,... Read More

Analysis of Lumbar Spine Stenosis Specimens for Identification of Transthyretin Cardiac Amyloidosis
NCT06034405
Recruiting
Primary objective: To identify older adults with transthyretin cardiac amyloidosis (ATTR-CA) early in the course of the illness, at a time when disease modifying therapies are most effective. The specific aims of this epidemiologic investigation include: 1. To identify subjects with previous lumbar spinal stenosis (LSS) Surgery who have evidence of transthyretin (TTR) amyloid deposits in spinal specimens and could be at risk for ATTR cardiac amyloidosis. 2. To evaluate for ATTR-CA among those... Read More

Transcranial Magnetic Stimulation for Chronic Neuropathic Pain
NCT05593237
Recruiting
Chronic neuropathic pain is defined as pain caused by a lesion or disease of the somatosensory nervous system. It is highly prevalent, debilitating, and challenging to treat. Current available treatments have low efficacy, high side effect burden, and are prone to misuse and dependence. Emerging evidence suggests that the transition from acute to chronic neuropathic pain is associated with reorganization of central brain circuits involved in pain processing. Repetitive transcranial magnetic stim... Read More
