A Study to Assess the Safety and Effects of ABBV-1758 Following Subcutaneous or Intravenous Injections in Participants With Alzheimer's Disease

Alzheimer's Disease

Alzheimer's disease (AD) is a progressive, irreversible neurological disorder and is the most common cause of dementia in the elderly population. Clinical symptoms of the disease may begin with occasional forgetfulness such as misplacement of items, forgetting important dates or events, and may progress to noticeable memory loss, increased confusion and agitation, and eventually, loss of independence and non-responsiveness. The purpose of this study is to test how safe ABBV-1758 is, how well it works, how the body processes it and what effects it has on the body. ABBV-1758 is an investigational drug being developed for the treatment of Alzheimer's disease. This study is conducted in 3 stages. Stage A is a multiple ascending dose study with a 1 in 5 chance (4:1 randomization) that participants are assigned to receive placebo. Stage B is a dose expansion phase, also using 4:1 randomization for ABBV-1758 or placebo. Stage C enrolls Japanese and Chinese participants with the same randomization scheme. Approximately 210 participants will be enrolled at about 55 sites in the United States, China, and Japan. Participants will receive intravenous (IV) or subcutaneous (SC) doses of ABBV-1758 or placebo once every 4 weeks (Q4W) for 24 weeks and will be followed for additional 12 weeks in the Follow-up Period. Participants will have the option of participating in a 12-month, blinded Extension Period receiving ABBV-1758 or placebo based on amyloid PET results. There may be higher treatment burden for participants in this trial compared to their standard of care due to study procedures. Participants will attend regular visits during the study at a hospital or clinic. The safety of the treatment will be checked by medical assessments, blood tests, and completing questionnaires.

Acoramidis Transthyretin Amyloidosis Prevention Trial in the Young (ACT-EARLY) Study in Asymptomatic Carriers of a Pathogenic TTR Variant

Amyloidosis · Amyloid Cardiomyopathy · Transthyretin Amyloidosis

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.

Trial-Ready Cohort-Down Syndrome (TRC-DS)

Down Syndrome · Alzheimer Disease · Dementia

The purpose of the Trial-Ready Cohort - Down Syndrome (TRC-DS) is to enroll 120 healthy adults with Down syndrome (DS), between the ages of 25-55, into a trial ready cohort (TRC), and up to 550 participants in total including co-enrolled in the Alzheimer Biomarkers Consortium - Down Syndrome (ABC-DS) study. Participants enrolled in the TRC-DS will undergo longitudinal cognitive and clinical assessment, genetic and biomarker testing, as well as imaging and biospecimen collection. Using these outcome measures, researchers will analyze the relationships between cognitive measures and biomarkers of Alzheimer's disease (AD) to identify endpoints for AD clinical trials in DS that best reflect disease progression. To learn more about the study and participating sites, visit our study website at: https://www.trcds.org/. TRC-DS is collaborating with the Alzheimer's Disease Biomarker Consortium-Down Syndrome (ABC-DS) to allow study participants to be concurrently enrolled in both ABC-DS and TRC-DS, referred to as "co-enrollment". ABC-DS is a longitudinal, observational research study that is overseen at University of Pittsburgh Coordinating Center. ABC-DS participants who express interest in potentially joining a clinical trial in the future and who meet TRC-DS eligibility criteria, may choose to co-enroll in TRC-DS at an ABC-DS Site. Co-enrolled participants will adhere to the ABC-DS protocol and schedule of activities, but agree to share their data with the TRC-DS team and to receive invitations for future participation in clinical trials. Fore more information on ABC-DS please visit https://www.nia.nih.gov/research/abc-ds or http://abcds.pitt.edu/.

Intervention to Collect and Utilize Sexual Orientation and Gender Identity (SOGI) Information in Hospice

Sexual and Gender Minorities · Hospice · Alzheimer's Disease and Related Dementias

Older sexual and gender minority (SGM) patients are at risk for receiving inequitable end-of-life care; those with Alzheimer's disease and related dementias (ADRD) are at particularly high risk. Failure to collect and integrate sexual orientation and gender identity (SOGI) data to identify patients' informal support systems may have adverse health consequences for SGM older adults, particularly for those dependent on informal caregivers to provide in-home support and assist with activities of daily living. The goal of this K01 is develop a novel training for hospice staff in person-centered communication that includes SOGI data collection to promote authentic end-of-life care for SGM patients and their caregivers.

Study to Investigate Vagus Nerve Stimulation to Augment Executive Function in Healthy and Cognitively Impaired Populations

Mild Cognitive Impairment (MCI) · Parkinsons Disease (PD) · Healthy Adult

This study plans to learn more about how stimulating the vagus nerve through gentle electrical stimulation applied to the ear can affect decision-making, problem-solving, and other thinking abilities. This process, called transcutaneous auricular vagus nerve stimulation (taVNS), could help improve brain function in both healthy individuals and people with Parkinson's disease (PD).

Study of LHP588 in Subjects With P. Gingivalis-Positive Alzheimer's Disease

Alzheimer Disease · Alzheimer Disease Due to P. Gingivalis

This study is to test LHP588 in persons who have mild to moderate Alzheimer's disease (AD) who have shown progressive mental decline in the last year and who have P. gingivalis (Pg) infection. P. gingivalis infection has been linked to the development of dementia. LHP588 is designed to target the P. gingivalis bacterium, to potentially help to halt or slow down the progression of AD and its symptoms. A saliva test will be done to determine P. gingivalis infection. Tests for AD include standard questionnaires such as MMSE and a blood test for pTau217. Treatment will be blinded, meaning the participant and the doctor will not know if the participant is receiving LHP588 or placebo. The total time for participation in the study may be up to 64 weeks. This includes a screening period (to ensure the participant is suitable for the study and the study is suitable for the participant) of up to 12 weeks, a treatment period of up to 48 weeks, and a safety follow-up period of 4 weeks after the last dose of the study drug to check the participant's overall health. Treatment is a once-a-day capsule. Caregiver participation is required. The study requires the participant to visit the study center (with the caregiver) at least 20 times within 64 weeks (this does not include any unplanned visits that may be recommended by the study doctor). In addition, the study doctor or clinic staff will contact the participant via phone at least 1 time.
