The purpose of the study is to learn about the safety and effects of the study medicine (called ritlecitinib) for the treatment of alopecia areata. Alopecia areata is a disease that causes hair loss on the scalp, face, and areas of the body. Ritlecitinib is approved in many countries at a dose of 50 mg (milligram) taken by mouth once a day for the treatment of patients 12 years and older with severe alopecia areata. This study will look at both the 50 mg dose and a 100 mg dose. This study is seeking participants who: * Are 12 years of age or older * Have a diagnosis of alopecia areata * Have lost 50% or more of the hair on their scalp * Do not have any other conditions that causes hair loss * Are willing to stop all other treatments that they may be taking for alopecia areata About 550 participants will take part in in this study. Participants will be chosen by chance, like drawing names out of a hat, to receive 1 of 2 different amounts of ritlecitinib (50 mg and 100 mg) taken by mouth once daily. The 2 doses of ritlecitinib in this study will be compared to each other and also to data from previous studies. This will help to see if the 100 mg dose of ritlecitinib is safe and effective. People will be in this study for about 13 months. During the study, participants will need to visit the study site up to 9 times. Participants will undergo various tests and procedures such as: * alopecia areata assessment, * physical examinations, * hearing tests, * blood tests, * x-ray, * ECG (electrocardiogram), * photographs of the scalp and eyes. Participants will also be asked to complete questionnaires about their alopecia areata. Read Less

The goal of this clinical trial is to learn if ESK-001 works to treat moderate to severe plaque psoriasis. The main questions it aims to answer are: * Does ESK-001 reduce the severity of people's psoriasis? * How safe is ESK-001 in people with moderate to severe plaque psoriasis? The study includes 2 comparators: a placebo control (a 'dummy' tablet that does not contain the medicine ESK-001 but looks just like it) and an active control (apremilast, which is a medicine approved to treat psoriasis). People taking part in this study must be men or women aged at least 18 years and have had plaque psoriasis for at least 6 months, currently moderate to severe. Participants will: * take drug every day for 24 weeks. * visit the clinic for checkups and tests. * fill out questionnaires about their psoriasis, itch severity, and change in quality of life. * be assessed for health issues and side effects, physical examinations, vital signs, heart electrical activity measurements, and psychological health. * provide blood and urine samples.

The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

The goal of this clinical trial is to learn if the intravaginal Cern device works to treat bacterial vaginosis and fungal vaginitis in premenopausal women. It will also learn about the safety of the device. The main questions it aims to answer are: Does the device accomplish symptom resolution and negative diagnostic tests post-treatment? What medical problems do participants have when using the intravaginal device? Participants will use the investigational intravaginal device for 5 consecutive days, participate in teleconferences and weekly follow-ups, attend in-clinic visits, and maintain a study diary.

This study will assess safety, tolerability, and treatment activity of datopotamab deruxtecan (Dato-DXd) in combination with immunotherapy with or without carboplatin in participants with advanced or metastatic non-small cell lung cancer (NSCLC). Read Less

Alopecia areata (AA) is a chronic relapsing autoimmune disease characterized by nonscarring hair loss affecting children, adolescents, and adults across all ages, races, and genders. AA primarily affects the scalp; however, it also can affect nails, eyelashes, eyebrows, and other hair follicles on the patient's body. The 3 main types of AA are: * Patchy alopecia (PA), as seen in 90% of clinical diagnoses * Alopecia totalis (AT), that affects all scalp hair * Alopecia universalis (AU), involving all scalp, face, and body hair Dermatologist preferences for utility and order of skin-directed therapies to treat AA vary widely, with treatment choices based on various factors such as patients' age, disease duration and severity (Meah et al., 2020). Ritlecitinib is a bioavailable small molecule that irreversibly binds to Janus kinase-3 (JAK3) and Tyrosine kinase Expressed in the hepatocellular Carcinoma kinase family (TEC). Ritlecitinib 50 mg once daily was approved by the FDA 23 June 2023 and EMA 20 July 2023 for the treatment of severe alopecia areata in adults and adolescents 12 years of age and older. In Japan, ritlecitinib was approved on 26 June 2023 for the treatment of alopecia areata (limited to intractable cases involving widespread hair loss). Additional countries have since approved ritlecitinib. Those approvals are based on the results of the ritlecitinib pivotal phase 2b/3 study (ALLEGRO 2b/3) which examined efficacy and safety of ritlecitinib in AA patients globally. Despite positive results from the ALLEGRO program, there is still lack of evidence on ritlecitinib patients' characteristics and clinical outcomes in routine clinical practice. The investigators will evaluate patient and disease characteristics, treatment patterns, and clinical and patient-reported outcomes among patients with AA who are receiving ritlecitinib. The aim of this study is to measure effectiveness of ritlecitinib in a real-world setting. Ritlecitinib will be prescribed to patients according to the approved product label. Treatment will be guided by clinical judgement of the treating physician ie, study investigators, according to standard of care, independently of this study. Read Less

The goal of this clinical trial is to learn if CGB-500 works to treat atopic dermatitis in participants ages 12 and older. The goal is also to learn about the safety of CGB-500. The main questions it aims to answer are: Does CGB-500 improve atopic dermatitis by decreasing the area affected and the severity of the lesions? What medical problems do participants have when taking CGB500? Researchers will compare CGB-500 to a placebo (a look-alike substance that contains no drug) to see if CGB-500 works to treat atopic dermatitis. Participants will: Take CGB-500 or a placebo every day for 8 weeks. Visit the clinic once every 2 weeks for the first month and at the end of 8 weeks. Keep a diary of when they use the product and complete a form about their symptoms including itching. Read Less

ABBV-RGX-314 (also known as RGX-314) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD or nAMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (anti-VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to maintain or prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every 4 to 16 weeks in frequency, to maintain efficacy. Due to the burden of these treatments, patients often experience a decline in vision with reduced frequency of treatment over time. Read Less
