This study will evaluate the effects of elafibranor (the study drug) in participants with Primary Sclerosing Cholangitis (PSC). PSC is a rare disease of the liver that leads to injury and destruction of bile ducts. Damage to bile ducts leads to buildup of bile in the liver, which then causes further damage, and leads to disease progression. This study will compare elafibranor to a placebo, a dummy treatment. The main objective of the trial will be to study the safety and side effects of the study drug. The trial will also study the study drug's effects on blood tests and other tests related to PSC disease activity.

Subjects entering this long-term safety extension (LTSE) study must have successfully participated in a pediatric LUM-201 GHD study through at least the 12-month visit and are eligible for continuation of treatment beyond Month 12, if applicable. Subjects may be enrolled into the LUM-201-02 study, having met all enrollment criteria, following successful completion of 12, 18, or 24 months of treatment in a pediatric LUM-201 GHD study.
Subjects who have met the AHV ≥ 6.7 growth criterion and have continued on treatment beyond the Month 12 visit in the LUM-201-01 trial may transition into the LUM-201-02 trial at Month 18 visit. For these subjects, AHV at Month 24 will be compared to AHV at Month 12, and if it is confirmed to be ≥ 80% of the Month 12 AHV, continued treatment with LUM-201 will be offered.

This is a Phase 3, placebo-controlled, randomized, double-blind research study evaluating the efficacy, safety, and PK of baricitinib in children from 6 years to less than 18 years of age with severe alopecia areata. The study is divided into 4 periods: a 5-week screening period, a 36-week double-blind treatment period, an approximately 2-year long-term extension period, and a 4-week posttreatment follow-up period. If the subject meets all eligibility criteria they will be randomized to receive either baricitinib high dose, baricitinib low dose, or placebo for 36 weeks. Participants will then be transitioned into the long-term extension treatment period. Subjects will attend 18 clinic visits for up to 145 weeks.

Individuals with Alpha-1 Antitrypsin Deficiency Associated Liver Disease who were enrolled in and completed the AROAAT2001 or AROAAT2002 study will be invited to participate in this study. This is a 2 year open label extension study of the drug Fazirsiran. Participants will receive 200mg of Fazirsiran every 12 weeks at the study site. Study visits will include blood work, pulmonary function test, questionnaires and liver evaluation testing. A liver biopsy will be performed at end of study, week 102. Potential risk include but are not limited to, allergic reaction to study medication or risk of infection or bleeding from biopsy. Safety and side effects of all assessments and therapies will be monitored throughout the study.

The purpose of this study is to identify whether investigational blood and tissue testing can detect cancer cells in the blood stream can tell if subjects are responding to their individual treatment plans.

Participation will last as long as the subject's individual treatment plan and will consist of collecting tissue biopsies (10 slides), which will be taken during the subject's standard of care procedure, as well as blood draws (between 1 and 2 tablespoons), which will be taken during each of the subject's standard of care clinic appointments throughout their care journey.

5-aminosalicylic acid (5-ASA) medications are first line treatment for mild to moderate Ulcerative Colitis (UC), comprise 81% of all UC prescriptions, and have a market share of 1.5 billion. However, despite 5-ASA frequency and optimization, 35% of patients fail induction therapy and 52% of patients fail to maintain remission at 12 months, requiring step up therapy to immunomodulators or biologics which have increased side effects and cost. This highlights a key challenge in UC which is to address the large inter- and intrapatient variabilities in both disease progression and variability in response to treatment. Chronotherapy is the timing of medical interventions according to the host circadian rhythms in order to optimize drug response and minimize toxicity, and is one explanation for the large variability in response to medications. The long-term objective of our research is to establish the hypothesis that is that appropriate time of day of administration of oral, once daily 5-ASA therapy in alignment with the host circadian rhythms will improve subclinical inflammation and microbial structure/function and increase mucosal 5-ASA levels. To test this hypothesis, In
response to the small R01 for pilot and feasibility clinical trials (PAS-20-160) and to test our hypothesis, we propose to conduct a six month, single center, randomized crossover pilot trial involving 60 subjects with inactive UC [Mayo score ≤2, endoscopic score 0-1] but subclinical inflammation [stool calprotectin > 50 mcg/g] on a stable dose of once daily 5-ASA medication. All subjects will be randomized to once daily 5-ASA medications two different times of the day: either between 06:00 – 10:00 h or 18:00 – 22:00 h. Three disease assessments will performed at: 1) enrollment just before randomization; 2) month 3, at the completion of first arm (condition 1), and 3) month 6, after completion of the second arm (condition 2). We will assess time impact of our chronotherapy protocol on: 1) subclinical inflammation (Aim 1): a) stool calprotectin; b) intestinal barrier integrity; and c) endoscopic/histology scores; 2) Microbiota: mucosal and stool microbiota structure and function (Aim 2); and 3) 5-ASA metabolism: a) increase mucosal levels of 5-ASA and b) mucosal NAT activity (Aim 3). In addition, optimal 5-ASA treatment (i.e., Aims 1-3) will depend upon host chronotype which will be monitored by validated questionnaires, rest-wake actigraphy, and urinary melatonin. The results of this innovative proposal will establish a key role for chronotherapy in the treatment of UC and provide pilot data for the future larger multicenter clinical trials. Chronotherapy will allow for a personalized medicine approach that incorporates circadian biology to improve efficacy and minimize intolerance in treatment of UC.

The main purpose of this study is to determine if XEN1101 can reduce the seizure frequency and if it is safe to use. Subjects who successfully completed and did not terminate early from one of the antecedent studies (X-TOLE2, X-TOLE3, or X-ACKT) are eligible to participate in X-TOLE4. Following enrollment into X-TOLE4, subjects will undergo a treatment period of up to 3 years, during which there will be a visit at 2-, 4-, and 13-weeks post-entry, with subsequent visits occurring at 13-week intervals during the first year, and then at 26-week intervals (with a telephone call in between) until dosing is completed. All subjects will be initially assigned to receive 25 mg QD of XEN1101. Study drug is to be taken with the evening meal. Subjects will be expected to keep a daily seizure eDiary with a minimum of 80% compliance for the duration of the extension study (reporting on ≥80% of days between visits).
Upon completion of dosing at the end of the treatment period, there will be an 8-week follow-up period.

This is a Phase I (determine the safety of a drug) study that is looking at how long the contrast agent gadoquatrane stays in the plasma (part of blood not including red cells) after a single injection during an MRI in children aged 0-18 years. Gadoquatrane is an investigational drug, which means that it is not approved by the FDA. This study will be assessing the safety of gadoquatrane for up to 8 days following the administration of gadoquatrane at the MRI. Blood samples will be collected three times within the 8 hours following the MRI for analysis of how much gadoquatrane is left in the blood.

About 380 males and females aged 55 to 90 years with psychosis associated with Alzheimer's disease will take part in this worldwide study. This study will be conducted at up to 100 sites in the United States, Canada, France, Germany, Spain and others in approximately 10 countries. The study will test KarXT, a combination of 2 study drugs, xanomeline tartrate and trospium chloride. Xanomeline tartrate stimulates the muscarinic receptors (a receptor in the nervous system) that is involved in cognitive and neurobehavioral functions. Stimulation of these receptors has been shown to effect changes in cognitive performance and promote antipsychotic activity. Trospium chloride is a muscarinic inhibitor that is expected to reduce the negative peripheral (outside the brain) muscarinic side effects of xanomeline tartrate without reducing its intended therapeutic effects in the brain.
The goal of this study is to assess whether KarXT helps in relapse prevention in people with psychosis associated with AD as compared to placebo, see how safe and well accepted KarXT is in people with psychosis associated with AD as compared to placebo, and check what the body does to KarXT and how long does it stay in the body (pharmacokinetics) as compared to placebo.

This study is designed to learn about the safety and effectiveness of a new gene therapy called KB408 for Alpha-1 Antitrypsin Deficiency (AATD). AATD is an inherited condition in which a person has low blood levels of a protein known as alpha-1 protease inhibitor (called Alpha1-PI). AATD causes an increased risk of chronic obstructive pulmonary disease (COPD) in the form of emphysema (long term lung disease) and, less frequently, other diseases.
KB408 delivers copies of the genes that produce AAT to the lungs and is given by inhaling a mist (called nebulization). The genes are carried and delivered by a modified herpes simplex virus type 1 (HSV-1). This virus is not harmful and simply acts as a vehicle to deliver the genes to the lungs. The genes that are delivered by KB408 do not change a person's own DNA. This is an open-label study, meaning that the participants, the study doctor, and the sponsor all know that the participants are receiving KB408. KB408 is an investigational product, meaning it is not approved for commercial use by the FDA.
Eligible participants will receive one of three doses of KB408. Participants will have a screening visit first to make sure that they are able to participate in the study. After the screening visit, participants will need to return to the study center 6 more times over 2 months. At the second visit, participants will receive the study drug. Each visit will take between 2 and 6 hours to complete. Study procedures include medical history collection, vitals, physical exam, ECG, spirometry and DLCO, urine cotinine test, blood work, cheek swab, sputum sample, and bronchoscopy (only for participants in cohorts 3a and 3b).
Possible side effects of KB408 include temporary increases in certain cell types in the lungs and temporary increases in the breathing rate after dosing. Since this is the first time that KB408 has been given to humans, it is possible that participants may have an immune reaction to the study drug. There is also a risk with genetic testing and a risk to confidentiality. Participants may not receive any personal benefit from being in this study. There is no guarantee that the Study Drug will help. The information that is collected from the study may help other people in the future.
