The purpose of this study is to test the safety of an investigational drug product, IBI-10090 (DEXYCU), in children to treat eye inflammation (redness) caused by cataract surgery. DEXYCU was approved by the FDA in February 2018 for use in adults, however; has not yet been approved for use in children. The active ingredient in DEXYCU is dexamethasone. Instead of being an eye drop containing dexamethasone, DEXYCU remains in the eye as a tiny droplet and slowly releases dexamethasone over a period of approximately two to three weeks. After that time the droplet is absorbed by the body. Subjects 0 to 3 years of age who are undergoing cataract surgery will be eligible for this study. The study starts at screening visit which is 3-29 days before surgery. Any study-related procedures will be performed only after obtaining informed consent. Child will be in the study for about 90 days after signing informed consent. Enrollment in this study requires a total of 8 visits. If child is eligible he/she will be randomly assigned (like the flip of a coin) to either study group DEXYCU or control group, prednisolone acetate. Child will have study visits 1 day following cataract surgery, and then at approximately 1 week, 2 weeks, 4 weeks, 6 weeks and 3 months after surgery. All visits are standard of care visits for all cataract surgery patients except 2 weeks and 6 weeks after surgery visits.

This study will test SAGE-718 to evaluate cognitive effects in subject with early manifest HD. The subject will be on study drug or placebo for 84 days. At clinic visits, participants will take the IP under staff supervision, followed
by assessments of cognitive function, health-related function and quality of life, and neuropsychiatric symptoms.

The purpose of this study is to see if the study drug BOTOX®, is safe and helps to reduce upper limb essential tremor in adults who experience persistent tremor during movement. The study is 38 weeks long and includes 12 clinic visits. Participants will be injected with the study drug or placebo 3 times over the 38 week period. The participant will have to complete a set of questionnaires and assessments at each visit.

This study will help determine the safety and effectiveness of BIIB122, compared to placebo (an inactive substance), in people with early-stage Parkinson's disease. The use of BIIB122 in this study is investigational. "Investigational" means that the study drug is currently being tested and is not approved by the U.S. Food and Drug Administration (FDA) or any other health authorities around the world for treating people with PD. The study is expected to last a minimum of 1 year to a maximum of 3 years. You may or may not receive direct medical benefit from participating in this study. Your condition may get better, worse, or stay the same. The information obtained from this study, however, could help other patients with your disease in the future.

This study is an open-label study that will evaluate SAGE-718 on the cognitive effects in subject with early manifest Huntington's Disease (HD). The subject will be on study drug for a year. At clinic visits, participants will take the IP under staff supervision, followed by assessments of cognitive function, health-related function and quality of life, and neuropsychiatric symptoms.

The purpose of this clinical trial is to evaluate the safety and efficacy of BIA-28-6156 in subjects with Parkinson's Disease (PD). BIA -28-6156 is an investigational drug meaning that its safety, effects and how it works are still being studied. This is a randomized (assigned by chance), placebo-controlled study, which means that some participants will receive a fake treatment (placebo) while others get the real treatment. The placebo treatment looks like the BIA-28-6156 medications but doesn't contain any active ingredient. The medication is in a pill form and will be administered orally. This research is also double blind, meaning that neither the participants nor the researcher will know which treatment they will be receiving. In Part A of this study, participants will be asked to give a blood sample for a genetic screening test. If genetic testing in part A indicates the person can participate, they may be asked to volunteer for part B. Duration of Part B is about 87 weeks, this includes 5 weeks for screening, 78 weeks for the double-blind treatment period, and 4 weeks for follow up. There are at least 11 visits in total in 20 months (9 clinic visits, 2 remote phone/video visits); this does not include unscheduled visits. During visits, participants should anticipate tests including electrocardiograms (ECGs), vitals measurements (including temperature, blood pressure, and heart rate), and a physical/neurological examination. Some of the risks includes fatigue, headache, drowsiness, muscle aches and possible worsening of PD symptoms. As for benefits, participants who receives the BIA drug may see their PD progression slowing.
