This study consists of 2 parts, Part A and Part B. Part A is a single center, randomized, double-blind, placebo-controlled cohort designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of NMRA-323511 among healthy elderly. Part B is a multicenter, randomized, double-blinded, placebo-controlled, parallel-group cohort to evaluate the safety, tolerability, and efficacy of NMRA-323511 among adults with Agitation Associated with Dementia due to Alzheimer's Disease. Part A consists of a Screening Period (up to 28 days), a 10-day Treatment Period, and a 10- day Follow-up clinic visit after last dose of study treatment. Part B consists of a Screening Period (up to 28 days), an 8-week Treatment Period, and a 10-day Follow-up clinic visit after last dose of study treatment. Read Less

This study is open to adults between 18 and 80 years of age. People with a body mass index (BMI) between 18 and 42 kg/m\^2 can take part. Women can only participate if they cannot get pregnant. This study includes people with mild liver problems, people with moderate liver problems, and people without liver problems as a matching control. The purpose of this study is to find out how mild and moderate liver problems affect how the body handles a medicine called zongertinib. Participants take zongertinib once as tablets. Participants with liver problems are treated in a step-by-step approach with a few days in between for the doctors to review the data and make sure the participants can tolerate the treatment. Participants may continue their regular treatment for their liver problems during the study. Participants are in the study for about 5 weeks. During this time, they visit the study site 4 times. This also includes an overnight stay for 6 nights. During study visits, the doctors regularly check participants' health and take note of any unwanted effects. To assess the study endpoints, the study staff regularly takes blood samples. Read Less

Background: During the first few decades of life, the brain changes dramatically in shape and function. Sleep lets researchers measure these changes. Researchers want to create a database of sleep and neurodevelopmental data in a group of infants and children to learn more. Objective: To address a knowledge and data gap in the field of sleep and neurodevelopment in infants and children. Eligibility: Children ages 6 months to 76 months who may or may not be at risk for neurodevelopmental and neuropsychiatric disorders. Also, children ages 6 months to 8 years who have a referral for a sleep study. Design: Participants will have neurodevelopmental testing. They will have a medical, psychiatric, and family history. They will have a physical and neurological exam. They will be interviewed and complete surveys. They will give a cheek swab and/or blood sample. Some participants will have 1 study visit that lasts 2 days. Other participants will have up to 4 study visits. Each visit will last 2 days. Visits occur every 8 months to 1 year, for a total participation time of 2 years. Participants will have a 20-minute daytime electroencephalogram (EEG), if possible. This EEG session will be used to calibrate the machine for the overnight study. Participants will take part in an inpatient overnight sleep study. Electrodes will be placed on the participants. For young children, parents will help place the EEG leads. Other sensors may also be placed. A gauze cap will be placed on participants head to protect the leads and keep the participants from moving them. 'Lights out' will occur as close to participants bedtime as possible. Read Less

The goal of this clinical trial is to assess the safety, tolerability, and pharmacokinetic profiles of Y-3 in healthy adult volunteers in the United States. The main questions it aims to answer are: * What the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers? * If drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers. Researchers will compare drug Y-3 (40 mg and 60 mg) to a placebo (a look-alike substance that contains no drug) to see what the pharmacokinetic profiles of single ascending doses of Y-3 (40 mg and 60 mg) in the US healthy adult volunteers and if drug Y-3 (40mg and 60 mg) is safe and tolerate in the US healthy adult volunteers. Participants will: * Take drug Y-3 (40 mg) or Y-3 (60 mg) or a placebo only once. * Answer questions regarding your medical history. * Comply with the study procedures and requests. * Complete all tests and collections of PK Sampling. * Must not have any special dietary requirements and be able to consume the food (low-fat) provided by Tranquil Clinical Research during your 4-night stay. * Must avoid excessive ( \> 8 cups per day) caffeine consumption (i.e. coffee or tea) during your time in the study. * Must not consume any food or beverage rich in grapefruit, papaya, or mango during your time in the study. * Must not take any other medications, including traditional Chinese medicines and herbal medicines, during your time in the study. * Must avoid sexual activity or use non-drug contraceptive measures (i.e. condoms) during your time in the study. * Female participants must not become pregnant while in the study. * Must not receive any vaccinations during your time in the study. * Must not donate blood for purposes outside of study procedures during your time in the study. * Must not drink alcohol during your time in the study. * Must not smoke during your time in the study. * Inform your Study Doctor if you no longer wish to participate in the study.

The main aim of this study is to understand how moderate and severe liver impairment (based on the Child-Pugh classification) affects the body's processing of a single dose of 10 mg maximum of palovarotene, compared to healthy participants with normal liver function. The study will also assess the safety and tolerability of the single dose of palovarotene. Participants will be enrolled in stages and divided into three groups based on their liver function: * Group 1: Healthy participants with normal liver function * Group 2: Participants with moderate liver impairment * Group 3: Participants with severe liver impairment (only enrolled if Group 2 results are safe and acceptable) Blood samples will be taken to assess how the drug binds to proteins in the blood. Participants will undergo various safety checks and procedures. Participants will stay in the clinical unit until Day 5 for these assessments and will return on Day 10 for a final visit. Read Less
