Alzheimer's Disease Clinical Trials in Houston, TX

This is a master protocol for 3 independent, seamlessly enrolling, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies in patients with ADP * Substudy 1 (Phase 2) will evaluate efficacy and dose response of ACP-204 30 and 60 mg vs placebo. This substudy will be initiated first. * Substudies 2A and 2B (both: Phase 3) will be confirmatory studies of either both doses (ACP-204 30 and 60 mg, respectively) or a single dose from Part 1 vs placebo. Substudies 2A and 2B will be performed independently of each other and will commence after enrollment of Part 1. All 3 substudies will be analyzed independently of each other. Each substudy individually will consist of a screening period (up to 49 days); a double-blind treatment period (6 weeks); a safety follow-up period (30 days) for patients not rolling over into an open-label extension study; and vital status follow-up (for patients who terminated their substudy early).

This is a Phase 3 global, multicenter, 52-week, open-label extension (OLE) rollover study for subjects completing study CN012-0026, CN012-0027 or CN012-0056. Subjects (randomized or non-randomized) who complete the 38-week CN012-0026 study, 14-week CN012-0027 study or 14-week CN012-0056 study will be eligible to enroll in CN012-0028. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with psychosis associated with Alzheimer's Disease. Read Less

The goal of this clinical trial is to learn if buntanetap/Posiphen works to treat early Alzheimer's disease in adults aged 55-85. It will also learn about the safety of buntanetap/Posiphen. The main questions it aims to answer are: * Does buntanetap/Posiphen improve cognition as measured by ADAS-Cog13? * Does buntanetap/Posiphen improve function as measured by ADCS-iADL? * What medical issues do participants have, if any, when taking buntanetap/Posiphen? Researchers will compare buntanetap/Posiphen to a placebo (a look-alike substance that contains no drug) to see if buntanetap/Posiphen works to treat early Alzheimer's disease. Participants will: * Take buntanetap/Posiphen or a placebo every day for 18 months * Visit the clinic periodically for checkups, tests, and questionnaires (screening visits, enrollment, month 1, month 3, month 6, month 9, month 12, month 15, month 18), including a volumetric MRI at month 6 and month 18 * Complete pre- and post-clinic visit phone calls Read Less

This is a study to evaluate the efficacy, safety, and tolerability of BMS-986368, a FAAH/MAGL inhibitor, for the treatment of agitation in participants with Alzheimer's Disease. Read Less

The goal of this pilot study is to test a combination of two non-invasive brain stimulation methods, called iTBS (intermittent theta burst stimulation) and tDCS (transcranial direct current stimulation), in people with Alzheimer's Disease (AD) and related dementias (ADRD). This study will also explore whether the combined treatment shows promise for reducing neuropsychiatric symptoms like mood swings, apathy, and agitation, and will evaluate the impact of the treatment on caregivers. The main questions the study aims to answer are: 1. Is the combined brain stimulation treatment practical and well-tolerated? 2. Do preliminary results suggest that this treatment could help manage neuropsychiatric symptoms and support a larger study? Participants will: * Attend nine in-person visits over three months. * Complete one week of in-clinic brain stimulation sessions (iTBS) followed by four weeks of daily at-home brain stimulation sessions (tDCS). * Take part in brain scans, questionnaires, and brain activity tests before and after the treatment. This pilot study is a first step to assess whether this combined treatment approach is practical and whether it has potential to improve symptoms, laying the groundwork for larger studies in the future.

This is a multicenter randomized, double-blind, placebo-controlled Phase 2 study designed to evaluate the efficacy, safety, and tolerability of two doses of CT1812 compared to placebo in participants diagnosed with early Alzheimer's disease. Read Less

The purpose of this study is to measure the difference in time to developing or worsening memory, thinking, or functional problems due to Alzheimer's disease occurring in participants receiving study drug compared to placebo. Participation could last up to 255 weeks including screening, a double-blind treatment period, and a double-blind observation period. In addition, eligible participants who receive placebo during the double-blind treatment period may choose to extend their study participation to receive open-label remternetug in an extension period.

The main purpose of this study is to look at how safe the study drug (mevidalen) is and whether it works to alleviate symptoms when given to people with mild to moderate Alzheimer Disease (AD) dementia. This is done by looking at participants: thinking and memory (cognition), everyday activities and sleep, AD symptoms, physical activity, irritability or anxiety. The study is expected to last approximately 26 weeks and may include up to 14 visits. Read Less

The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EOnonAD) participants, and (3) cognitively normal (CN) control participants.

Bio-Hermes-002 is a 120-day cross-sectional study that will result in a blood, CSF, retinal, digital, MRI, and PET brain imaging biomarker database that can be used to determine the primary objective. Digital biomarkers and blood-based biomarkers will be tested to determine whether a meaningful relationship exists between biomarkers alone or in combination with tau or amyloid brain pathology identified through PET images.

The main purpose of this study is to evaluate the safety and efficacy of donanemab in participants with preclinical Alzheimer's Disease (AD). Approximately 800 additional participants will be enrolled in a 12-month addendum to assess safety of a different titration regimen. Read Less

The purpose of this study is to test the safety, tolerability, and effects of choline in people with increased risk of Alzheimer's Disease (AD), also known as pre-symptomatic AD. Choline is a dietary supplement, but is being investigated to see if it has any effects on the progression to AD. Read Less
