Researchers are studying a treatment called MK-2214 to see if it can slow certain brain changes in people with early Alzheimer's disease (AD). AD is a form of dementia that causes memory loss, difficulties with communication, and challenges in decision-making, which affect daily activities. The study aims to find out if MK-2214 can slow the spread of tau protein in the brain compared to a placebo and to assess the safety and tolerability of MK-2214. Participants will receive either MK-2214 or a placebo through an intravenous (IV) infusion. The study is designed as a phase 2, randomized, placebo-controlled, double-blind trial with parallel groups. The treatment period lasts up to about 23 months, during which participants will receive infusions as scheduled. The placebo looks like the study treatment but contains no active drug, helping researchers understand the treatment's effects. Throughout the study, participants will be monitored for changes in tau protein levels in the brain using PET scans and for any adverse events or side effects. Researchers will track the number of participants experiencing adverse events and those who stop treatment because of them, with safety follow-up lasting up to approximately 26 months. Participants will also undergo brain imaging such as CT, PET, or MRI scans. The study involves regular assessments to measure the treatment's impact and ensure participant safety over the study duration.

Researchers are evaluating a new treatment for adults aged 18 to 65 who have Social Anxiety Disorder triggered by public speaking. This Phase 2 clinical trial in the U.S. aims to study the effects, safety, and tolerability of repeated doses of Fasedienol Nasal Spray given intranasally. The study focuses on how well this treatment relieves acute anxiety symptoms caused by a public speaking challenge in a controlled clinical environment. Those who complete the initial study may also join an open-label extension to assess long-term safety and tolerability when using the nasal spray as needed for up to 12 months. Participants will be assigned to one of three groups receiving nasal spray doses 20 minutes before their public speaking challenge. One group gets two doses of Fasedienol Nasal Spray spaced 10 minutes apart, another group gets one dose of Fasedienol followed by a placebo dose, and the last group receives two placebo doses. The study compares these dosing schedules to see which best relieves anxiety symptoms. In the extension phase, eligible participants can use 3.2 micrograms of Fasedienol Nasal Spray up to six times daily for a year to monitor longer-term effects. During the study, participants will undergo clinical evaluations including anxiety rating scales and distress measurements before and after treatment. Researchers will assess responses to the public speaking challenge and monitor safety through physical exams and laboratory tests. The main outcome measured is the Subjective Units of Distress Scale over seven days between visits. Safety, tolerability, and symptom relief will be closely tracked throughout both the initial and extension phases, which together may last up to 12 months for some participants.

Researchers are evaluating the effectiveness of pembrolizumab combined with sacituzumab govitecan-hziy compared to the standard chemotherapy treatments in patients with locally advanced or metastatic urothelial cancer. This Phase III trial focuses on cancers that have spread to nearby tissues, lymph nodes, or other parts of the body. The study aims to compare overall survival and other outcomes such as progression-free survival, response rates, clinical benefits, duration of response, and treatment toxicity between the two treatment approaches. Quality of life and fatigue are also assessed as secondary measures. Participants are randomly assigned to one of two treatment groups. One group receives standard of care chemotherapy, which may include carboplatin or cisplatin combined with gemcitabine, or alternatively docetaxel or paclitaxel, administered intravenously in cycles every 21 days for up to six cycles, unless the disease progresses or side effects become unacceptable. The other group receives sacituzumab govitecan-hziy intravenously on days 1 and 8, along with pembrolizumab intravenously on day 1 of each 21-day cycle, continuing for up to 35 cycles or two years, unless there is disease progression or unacceptable toxicity. Throughout the study, participants undergo regular blood sample collections and imaging scans using computed tomography or magnetic resonance imaging to monitor their condition. Quality of life questionnaires are also completed to assess symptoms and fatigue over time. After treatment ends, patients are followed up 30 days later and then annually for up to five years to evaluate long-term outcomes and safety. The main outcome measured is overall survival from the time of randomization up to five years.
