Hepatic Impairment

The purpose of this study to understand how the study medicine atirmociclib behaves in the body and how safe it is for people with different levels of liver health. The study is seeking participants who are: * Aged 18 years or older * Have a BMI of 17.5 to 40 kg/m2, and body weight more than 50 kg. * Have normal liver function or have stable mild, moderate, or severe liver disease Participants will receive study medicine by mouth. Blood samples will be collected to see how much of the medicine is in the body over time. This will help understand whether liver disease changes how the medicine is handled. Participants will be in the study for about 9 weeks. Those with normal liver function will stay in the clinic for about 7 days. People with liver disease will stay for about 9 days. After leaving the clinic, people may be contacted for follow-up. This may be done by phone or through a clinic visit.

The purposes of this study are to determine: * The pharmacokinetics (the amount of study drug in your blood and how long it takes the body to get rid of it) of the study drug and its metabolites (substances produced as the body breaks down the study drug) in participants with moderate or severe liver function impairment compared to participants with normal liver function (also known as a healthy volunteer). Pharmacokinetics (or PK) is the study of how your body absorbs, breaks down, and removes a study drug. * How well the study drug is tolerated and any side effects that may occur in participants with moderate or severe liver function impairment compared to participants with normal liver function. This study is for research purposes only and is not intended to treat any medical condition.

The purpose of this study is to determine the pharmacokinetic and safety of BMS-986435 in participants with normal hepatic function and participants with different degrees of hepatic impairment

The primary purpose of the study is to determine the effect of mild, moderate, and severe hepatic impairment on the PK of total treprostinil palmitil (TP) and treprostinil (TRE) following a single dose of 80 micrograms (μg) TPIP, when compared to normal hepatic function.

This study is open to adults aged between 18 and 80 years of age with a body mass index (BMI) of 18.5 to 42 kg/m². People with or without liver problems can take part in the study. The purpose of this study is to find out how much of a medicine called BI 1291583 gets into the blood of people with and without liver problems. BI 1291583 is being developed to treat people with bronchiectasis, a chronic disease of the lungs. People living with this condition often also have liver problems. Therefore, it is important to find out whether liver problems influence the amount of BI 1291583 that gets into the blood. Study participants receive a single dose of BI 1291583 as a tablet taken by mouth. Participants are divided into 4 groups based on how well their liver works: 1 group without liver problems, and 3 groups with mild, moderate, and severe liver problems. Each participant without liver problems is matched with participants from the other groups based on factors such as age, sex, smoking habits, and body weight to ensure accurate comparisons. Participants are in the study for about 3 months. They stay for 3 days at the study site and also visit the study site up to 9 times. During these visits, the doctors collect information about participants' health. To assess the study endpoints, the doctors regularly take blood samples from the participants. The doctors regularly check participants' health and take note of any unwanted effects.

This open-label study will evaluate the effect on the pharmacokinetics (PK), safety, and tolerability of a single oral dose of inavolisib in participants with moderate or severe hepatic impairment compared with demographically matched healthy participants with normal hepatic function.

The purpose of this study is to examine the safety and tolerability of AZD6234 and AZD9550 in participants with hepatic impairment and participants with normal hepatic function.

The purpose of this study is to understand the effects of decreased liver function on the study medicine (PF-07328948). People with decreased liver function may process the study medicine differently from healthy people. Study is seeking participants who: * Are between 18 and 75 years of age. * Have a BMI (body mass index) of 17.5 to 40 kg/m2, inclusive, and a total body weight of more than or equal to 45 kilograms or 99 pounds. Participants will take the study medicine as a tablet once at the study clinic and then will stay onsite for about 6 days. During this time, the study team will check for the participant's treatment experience and take some blood samples to test the level of PF-07328948. This will help understand if certain level of decreased liver function could affect the study medicine being processed in the body.

This study is open to healthy people and people with liver problems. Adults between 18 and 80 years can participate. The purpose of this study is to compare how a medicine called BI 3000202 is handled by the body in people with and without liver problems. All participants take 1 tablet of BI 3000202. Participants with liver problems may also continue their regular treatment for their liver condition. Participants are in the study for about 1 month. During this time, participants visit the study site about 11 times. Where possible, some of these visits may happen by phone. For some visits, participants stay at the study site overnight. Doctors regularly test the amount of BI 3000202 in the blood and check for any health problems.

This Phase 1, open-label study will evaluate the pharmacokinetics (PK), safety, and tolerability of a single oral dose of radiprodil in adults with varying degrees of hepatic impairment compared with healthy participants. Radiprodil is being developed as a potential treatment for GRIN-related neurodevelopmental disorders, tuberous sclerosis complex, and focal cortical dysplasia. Approximately 40 adults aged 18 to 75 years will be enrolled into five cohorts based on liver function (mild, moderate, or severe hepatic impairment) or healthy status. Participants will receive a single 15 mg oral dose of radiprodil and remain in the clinical research unit for intensive PK and safety monitoring through Day 6. The primary objective is to characterize the PK profile of radiprodil in participants with hepatic impairment compared with healthy participants. Safety and tolerability will also be assessed. Results from this study will help determine whether dose adjustments are needed in individuals with impaired liver function.

To Assess the Effect of Severe Hepatic or Renal Impairment on the Pharmacokinetics of Bemnifosbuvir/Ruzasvir After a Single Dose

This study will evaluate and compare the PK in subjects with severe HI to that of matched healthy control subjects with normal hepatic function.

The purpose of this study is to learn what happens to calderasib levels in a person's body over time. Researchers will measure what happens to calderasib levels in the body when it is given to participants with hepatic (liver) impairment and healthy participants. Researchers also want to learn about the safety of MK-1084 when it is given to people with hepatic impairment and if people with hepatic impairment can tolerate it.

A Phase 1, Open-label Extension Groups Study in Subjects having Hepatic Impairment with Cirrhosis due to Cholestatic Liver Disease

The primary purpose of the study is to evaluate the effects of mild and moderate hepatic impairment on PK of tasurgratinib after a single dose administration.

The primary purpose of this study is to evaluate the plasma PK of zanzalintinib following a single dose in participants with moderate liver dysfunction compared to matched healthy participants with normal liver function.

In this study, a single dose of VIR-2218 up to 200 mg SC or VIR-3434 at 300 mg SC monotherapy or a combination of VIR-2218 and VIR-3434 will be administered to assess the pharmacokinetic (PK) exposure, safety, and tolerability of VIR-2218 and VIR-3434 in participants with cirrhosis and Hepatic Impairment, defined using the Child-Pugh-Turcotte (CPT) categorization.

The current study is proposed to evaluate whether there is any clinically meaningful effect of hepatic impairment on the plasma Pharmacokinetic (PK) of HDM1002

The purpose of this study is to assess how fast RAY1225 gets into the blood stream and how long it takes the body to remove it in participants with impaired liver function compared to healthy participants.

The goal of this clinical trial to learn how MDMA is processed in people with abnormal liver function. The main questions it aims to answer are: Do people with abnormal liver function experience greater absorption of MDMA? Does the dose of MDMA need to be adjusted in people with abnormal liver function? Researchers will compare people with abnormal liver function to people with normal liver function. Participants will receive a single dose of MDMA then undergo periodic vitals measurements. They will remain at the study site for two more days undergoing more vitals measurements and having subjective effects and adverse events measured.
