In this study, researchers will learn how the body processes litifilimab when it is given under the skin in 3 different ways. Currently, ongoing studies utilize pre-filled syringes (PFS) that can deliver litifilimab subcutaneously (SC), also known as under the skin. In this study, researchers want to learn more about new ways of delivering litifilimab SC using either an autoinjector (AI) or an on-body injector (OBI): Both devices are designed to deliver litifilimab in an automatic way, especially helping patients who may not be able to use their hands very well, or who may be afraid of needles. While the AI is handheld, the OBI device works by being placed on the skin and can help deliver the highest amount of litifilimab through a single injection. The main objective of this study is to learn how the body processes litifilimab after using the AI device or the OBI device, as compared to using the PFS method. The main questions researchers want to answer are: * What is the highest amount of litifilimab found in the blood after dosing? How much total litifilimab is found in the blood throughout the study? Researchers will also learn more about: Any medical problems the participants have during the study * Any injection site pain or reactions the participants may have. Any skin reactions to the OBI device * Any changes in the participants' overall health after receiving litifilimab. This study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 4 weeks, after which selected participants will check into their study research center. * Participants will be randomly assigned to be in Part 1 or Part 2 of the study: * Part 1: Participants will receive SC injection(s) of litifilimab through either the AI device or through PFS. * Part 2: Participants will receive SC injection(s) of litifilimab through the OBI device or through PFS. * Participants will remain at their study research center for the first 8 days. After that, there will be a follow-up period for 17 weeks during which participants return to the center a total of 6 times. Each participant will be in the study for about 22 weeks. Read Less

In this study, researchers will learn how the heart reacts to multiple doses of BIIB091 in healthy participants. In previous studies looking at BIIB091, researchers have found that a certain range of doses can cause changes in the electrical activity of the heart. In this study, researchers want to learn more about that activity after participants take BIIB091 at lower and higher doses for 5 days. The main objective of this study is to learn how the heart's electrical activity changes after taking BIIB091. To measure this, researchers will look at something called the QT interval corrected for heartbeat, also known as "QTc". This represents the time it takes for the heart to contract and relax. A QT interval that is too long means that the heart's electrical system is taking longer than normal to recharge between heartbeats. This could increase the risk of abnormal heartbeats that may lead to sudden death. The main questions researchers want to answer are: • What is the change in the participants' QTc after taking BIIB091? Researchers will also learn more about: * Any changes in other measures of the heart's electrical activity * How the body processes BIIB091, as well as something called "M23", which is made in the body when BIIB091 is broken down * Any medical problems the participants have during the study * Any changes in the participants' overall health during the study This study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 29 days, after which participants will check into their study research center. * Participants will be randomly assigned to be in 1 of 2 groups: * Group 1: Participants will take a low dose of BIIB091 for 5 days followed by a high dose of BIIB091 for 5 days. * Group 2: Participants will take a single dose of moxifloxacin. Moxifloxacin is an antibiotic used to treat bacterial infections. Researchers are using it in this study to compare to BIIB091, because it is known to cause abnormal changes to the heart's electrical activity. * Participants in both Group 1 and Group 2 will also take a placebo while at the study research center. A placebo looks like the study drug or moxifloxacin, but does not have any real medicine in it. * Participants will remain at their study research center for 15 days. Afterwards, there will be a follow-up visit 11 to 14 days after each participant's last dose. Each participant will be in the study for up to 57 days. Read Less

The primary goal of this phase 1 study is to evaluate the effect of food and cobicistat on the pharmacokinetics of plixerafenib in healthy volunteers. Healthy male and female participants between the ages of 18 and 55 will be enrolled into this study. This study is looking to examine the following in two parts: Part A * The effect of food on the single dose PK of plixorafenib administered with cobicistat. * The effect of cobicistat administration on the single dose PK of plixorafenib. * The safety of plixorafenib administered alone and with cobicistat in a single dose regimen in healthy participants. Part B * To examine the effect of a high-fat and a low-fat meal versus fasted state on the single dose PK of plixorafenib administered alone. * To examine the effect of a low-fat meal versus fasted state on the single dose PK of plixorafenib administered with cobicistat. * To determine the safety of plixorafenib administered alone or with cobicistat (low-fat meal only) in a single dose regimen.

The goal of this clinical trial is to test a culturally tailored health promotion intervention for children with IDD and their families. First investigators will conduct a single group design pilot study of a health promotion intervention, followed by second, a small-scale randomized control trial (RCT). of the intervention with Latino parents of children with intellectual and developmental disabilities (IDD) in the Chicago, Illinois and Austin, Texas areas. The following research questions will be addressed: Question 1: What is the appropriate content, dosage, and delivery method of the intervention? Question 2: What is the feasibility and acceptability of the intervention? Question 3: Do participants improve between pre and post-test on outcome measures both in the one group design and compared to the control group in the RCT? Parents will receive 10 weekly remote sessions on health promotion content delivered by parent mentors called promotoras. Parents and children will attend 3 multi-family group workshops in-person that will provide demonstrations and interactive activities. Read Less

Injuries affecting the central nervous system may disrupt the cortical pathways to muscles causing loss of motor control. Nevertheless, the brain still exhibits sensorimotor rhythms (SMRs) during movement intents or motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. Brain-computer interfaces (BCIs) can decode SMRs to control assistive devices and promote functional recovery. Despite rapid advancements in non-invasive BCI systems based on EEG, two persistent challenges remain: First, the instability of SMR patterns due to the non-stationarity of neural signals, which may significantly degrade BCI performance over days and hamper the effectiveness of BCI-based rehabilitation. Second, differentiating MI patterns corresponding to fine hand movements of the same limb is still difficult due to the low spatial resolution of EEG. To address the first challenge, subjects usually learn to elicit reliable SMR and improve BCI control through longitudinal training, so a fundamental question is how to accelerate subject training building upon the SMR neurophysiology. In this study, the investigators hypothesize that conditioning the brain with transcutaneous electrical spinal stimulation, which reportedly induces cortical inhibition, would constrain the neural dynamics and promote focal and strong SMR modulations in subsequent MI-based BCI training sessions - leading to accelerated BCI training. To address the second challenge, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to the voluntary activation of the primary motor cortex through MI can help differentiate patterns of activity associated with different hand movements of the same limb by consistently recruiting the separate neural pathways associated with each of the movements within a closed-loop BCI setup. The investigators study the neuroplastic changes associated with training with the two stimulation modalities. Read Less
