This study examines eye movements and the pupil's response to light in progressive supranuclear palsy (PSP), comparing to Parkinson's disease and control subjects without neurological disease. Computerized measures of eye movements and pupil changes will be used. Subjects will also receive an eye exam to rule out other eye diseases. The goal of this study is to use subtle changes in eye movements and the pupil's response to light for earlier diagnosis of PSP.

Protein S is a protein that is very important to the blood clotting process. When people don't have enough Protein S they run the risk of developing blood clots. This study is collecting samples from people who may have abnormal Protein S levels in order to develop a new way of checking the Protein S levels. This test is looking specifically for FREE Protein S. The free protein S is Protein S that is not bound or "tied up" and is therefore more ready to do its job in the clotting process.

Alpha-1 antitrypsin (Alpha-1, AAT) deficiency is an inherited disease which results from a defect in the alpha-1 gene. Severe AAT deficiency causes emphysema predominant chronic obstructive pulmonary disease (COPD). This is a first in man study of gene therapy to insert a normal Alpha-1 gene into the cells of the body and attempt to make a normal Alpha-1 antitrypsin protein. The purpose of this Phase I/II study is to test the safety of a new gene therapy called AAVrh.10h ?1AT. This gene therapy uses a viral vector called Adeno-Associated Virus to insert the normal Alpha-1 gene into the cells of the body when the vector is placed into the bloodstream or pleural space.

Subjects who completed Study ALX0681-C301 (HERCULES) will be given the option to participate in this follow-up study which requires a clinic visit every 6 months for 3 years. Should the subject present with a recurrence of TTP during this time they will be treated with caplacizumab in addition to receiving standard of care treatment.

Lymphangioleiomyomatosis (LAM) is a rare lung disease that is caused by genetic mutations. It results in the uncontrolled growth and proliferation of an atypical smooth muscle cells in the lung. These cells invade airways, blood vessels, and lymph vessels, and limit the flow of air, blood, and lymph, respectively. The source of the cells is unknown, but available evidence indicates they arise from an extrapulmonary source. Their aberrant behavior is due to mutations in tuberous sclerosis genes that results in mTOR activation. Respiratory failure, lung collapse (pneumothorax), and pleural effusions (chylothorax) are hallmarks of the disease. This study will evaluate the safety and durability of the mTOR inhibitors sirolimus and everolimus, which are FDA approved medications for prevention of rejection of transplanted organs, in stabilizing or improving lung function in people in LAM.

Subjects are being asked to volunteer for this research study because they have been diagnosed with Dermatomyositis (DM). This study will test the safety and effectiveness of the investigational new drug, IMO-8400. Subjects will receive a subcutaneous injection of the study drug or placebo once a week for up to 24 weeks during the study. Subjects will complete a total of 27 visits over the course of 32 weeks. After the baseline visit, subjects will have the option of having a visiting nurse (who has been trained in the protocol and approved by the Sponsor) conduct the intervening weekly study visits 2-25 outside of the clinic (e.g., at your home or workplace) rather than coming in to clinic for injections.

Individuals with a confirmed diagnosis of alpha-1 antitrypsin (AAT) deficiency and emphysema will be invited to participate in this study. This study will determine the safety and effectiveness of Inhaled Hyaluronic Acid solution as a possible treatment of emphysema in AATD patients. A participant in this study will be asked to inhale the study medication or a placebo delivered by a nebulizer twice a day for 28 days. Neither the study investigators nor the participant will know if they are receiving active drug or placebo. Safety and side effects of all therapies will be monitored.

The purpose of this study is to evaluate the safety and efficacy of an investigational drug in adults with a clinical diagnosis of acquired Thrombotic Thrombocytopenic Purpura (TTP). This study aims to determine if patients receiving caplacizumab respond better than patients receiving placebo measured by time to normalized platelet count. The study drug will be given in addition to the standard of care treatment. The study of this investigational drug represents a novel approach to the treatment of this rare condition and may provide significant benefit in terms of the quality of life to patients with TTP. Participation in the study will involve a minimum of 8 visits to the study clinic over a period of two to six months based on treatment needs.

Individuals with alpha-1 antitrypsin (AAT) deficiency (AAT blood level lower than 11 micro-moles) and emphysema will be invited to participate in this study. This study will determine the impact of IV Alpha-1 proteinase inhibitor (Alpha-1 MP) on the progression of emphysema in patients with AAT deficiency. A participant in this study would receive either GLASSIA dosed at 60mg/kg with a high particle load or GLASSIA dosed at 60mg/kg with a low particle load. Neither the study investigators nor the participants will know which batch of drug is actual given to the participant. Participants will have the IV therapies given to them weekly for 25 weeks, with some infusions given at MUSC and some at home. Safety and side effects of all therapies will be monitored.

The purpose of this medical research study is to evaluate the safety and effectiveness of a new medication called imatinib mesylate in the treatment of Lymphangioleiomyomatosis (LAM). LAM is a rare disease in which abnormal cells (called LAM cells) grow out of control. Over time, LAM cells destroy healthy lung tissue and cause respiratory disease or failure.

Many patients with LAM are currently treated with a medication called sirolimus (rapamycin). Sirolimus slows the growth of LAM cells.

Imatinib mesylate (hereafter called imatinib) is approved by the Food and Drug Administration (FDA) for the treatment of some cancers that share common pathways with LAM cells. Laboratory studies suggest that imatinib could completely block the growth of LAM cells through initiation of targeted cell death.

An important purpose of this research is to determine the safety of imatinib in people with LAM. This study will also evaluate the short-term effectiveness of imatinib. Participants will be randomized to receiving imatinib (study medication) or placebo (no treatment) for the 56 day duration of participation. The study is being conducted at the Medical University of South Carolina and at Columbia Univerity in New York. Each site will enroll 10 participants.
