This study is for patients with pancreatic cancer. The purpose is to see if researchers can increase the chance of pancreatic cancer staying away by giving them chemotherapy before and after surger

The purpose of this study is to see whether Ozanimod is safe and effective for treating Crohn's disease. Participants who are aged 18 to 75 years with moderately to severely active Crohn's disease may be eligible.

To do this, a comparison will be made between subjects who receive active drug and subjects who receive placebo (a ‘dummy treatment' that looks like the active drug but contains no active ingredient). The chance of being randomized (like drawing names out of a hat) into ozanimod group and receiving ozanimod is 67%. The chance of being randomized into placebo group and receiving placebo is 33%.

This study is designed to last up to 30 weeks, including 2 screening visits, 4 study visits, and 2 follow-up visits. The study drug may improve participant's Crohn's disease condition, but this cannot be guaranteed.

This study is for patients who have been diagnosed with head and neck squamous cell carcinoma (HNSCC) that has returned (recurrent) or spread after previous treatment (metastatic). The investigational drug in this study is lenvatinib. The study will also use lenvatinib in combination with pembrolizumab, which is also experimental. The purposes of this study are to: test the safety of the study drugs, lenvatinib alone, pembro and lenvatinib together, and standard chemotherapies alone in the treatment of HNSCC; see how well the combination of pembro and lenvatinib works, compared to standard chemotherapies; and see if participants who get pembro and lenvatinib live longer than those who are treated with standard chemotherapies. Participants can expect to be on this study for about 48 months.

This is a study to find out if a device that temporarily alters brain activity (repetitive transcranial magnetic stimulation, rTMS) might be used to change how people with anxiety or related concerns cope with emotional situations. The study is recruiting people who recently started treatment for anxiety or a related concern. The study involves 3 visits to MUSC. At the first visit, participants do interviews and surveys asking about anxiety and related concerns, and they also do tasks where they see and react to emotional pictures while their brain activation is measured. At the next two visits, participants receive rTMS that uses a magnet placed on top of the head to alter brain activity temporarily (for about an hour). After rTMS, participants do two tasks where they see and react to emotional situations while wearing sensors on their hand, arms, face, and head.

Each visit in this study is expected to last between 2 – 3 hours. This study is not a treatment study, but it could help improve treatment in the future. Participants in this study are paid for their time.

The purpose of this study is to see whether oral Ozanimod is safe and effective for treating Crohn's disease. Adult participants (at least 18 years old) with moderately to severely active Crohn's disease may be eligible.

Only participants who complete the induction and/or maintenance study will be eligible to join this open-label study.

All participants in this study receive active study drug. The dose of study drug you will receive will depend on your prior study. There is no chance of placebo in this study.

This study is designed to last up to 234 weeks (4.5 years). Participants are expected to come to MUSC every 8 or 12 weeks for study visits.

The purpose of this study is to see whether Ozanimod is safe and effective for treating Crohn's disease. Adult participants (at least 18 years old) with moderately to severely active Crohn's disease may be eligible.

To do this, a comparison will be made between subjects who receive active drug and subjects who receive placebo (a ‘dummy treatment' that looks like the active drug but contains no active ingredient). The chance of being randomized (like drawing names out of a hat) into ozanimod group and receiving ozanimod is 50%. The chance of being randomized into placebo group and receiving placebo is 50%.

If participants' Crohn's disease condition get worse during the study, they will be invited to participate the open-label study, which has no placebo.

This is a one-year study, and participants are expected to come to MUSC every 8 weeks for study visits.

This study is for patients that have been diagnosed with recurrent or new head and neck squamous cell carcinoma (HNSCC). Patients either have had a recurrence (the tumor has comeback) or a new head and neck cancer in a different area of the head and neck (second primary) which has been removed by surgery. The study drug used is called pembrolizumab. The purpose of this study is to see if adding pembrolizumab to radiation or if using pembrolizumab by itself after surgery compared to the usual approaches with chemotherapy and radiation will increase life expectancy. Participants can expect to be on this study for up to 12 months and then followed for 5 years.

This study is for patients who have been diagnosed and previously treated stage IV or recurrent KRAS G12C mutated non-squamous non-small cell lung cancer. The purpose of this study is to see if we lower the chance of the growth or spread of KRASG12C-mutated advanced non-squamous non-small cell lung cancer by using the study drug AMG 510. Participants can expect to be on this study until disease progression, the side effects become too severe, or the participant decides to discontinue the study.

We plan to obtain skin biopsies from patients with systemic sclerosis and healthy donors to grow cells from biopsies. With those cells, we will use them in experiments to see why the cells from systemic sclerosis patients have more fibrosis compared to patients without systemic sclerosis.

The purpose of this study is to see if taking mepolizumab is safe and effective in treating Hypereosinophilic syndrome (HES) in children and adolescent patients ages 6 to 17 years who are receiving standard of care (SoC) therapy. Mepolizumab is administered through a subcutaneous injection (shot). Participation in the study will last for about 64 weeks approximately (1 year and 3 months).
