CGD disorders are a group of diseases that cause the immune system to function abnormally, leading to infections, autoimmunity and/or inflammation that can begin early in life. CGD is usually caused by changes in certain genes in DNA. Researchers are trying to learn what types of medical problems patients with CGD have and how these respond to treatment, including bone marrow transplantation and gene therapy. Researchers also want to learn which genes cause CGD and how specific gene abnormalities lead to medical problems.

This study is testing a new digital tool designed to help people who smoke during a quit attempt. The tool is a conversational program that uses artificial intelligence to provide personalized support and suggestions when people are facing situations where they might be more likely to smoke. The goal of the study is to see how easy the tool is to use, whether people find it helpful, and whether it may support smoking cessation.

Stem cell transplants (sometimes referred to as a bone marrow transplants) have been done for over 40 years but research continues to further refine the method to reduce side effects without affecting transplant success. The purpose of this study is to improve on transplant outcomes while reducing the potential side effects based on what has been learned from previous transplant studies using a reduced intensity preparative regimen. Information collected during this study (transplant outcomes and side effects) will be compared with the outcomes of the previous reduced intensity conditioning transplant study that enrolled more than 300 patients since 2002.

The purpose of this study is to learn if removing the donor T cells from the donor product using this new method will be a better way to reduce the risk of GVHD. The benefit of removing these cells with this new method is that they will prevent GVHD without requiring drugs to suppress the immune system. Potentially, the immune system will recover from the transplant faster, which in turn will also lessen the risk of severe infections. As well, the patient will not have the other common undesired side effects of these immunosuppressive drugs.

This study aims to better understand how infants' and toddlers' senses, movement skills, and brain development are connected. Researchers will use developmental assessments and brain imaging (MRI) to learn more about children who experienced a brain injury around the time of birth.

This study is about decision making in psychosis spectrum disorders, like schizophrenia.

We hope to improve our understanding of psychosis to help people in the future.

Ritlecitinib (LITFULO™, PF-06651600) 50 mg daily is currently approved for people 12 years of age and older to treat severe alopecia areata (hair loss). Ritlecitinib 100 mg will be compared to Ritlecitinib 50 mg to find out if a larger daily dose is safe and can improve regrowth of hair. The study will last about 57 weeks and will have up to 9 visits. Everyone will get one of the two doses of the study drug.

We are doing this research to collect a wide range of samples, clinical information, and measurements that will be used for future research into ALS and related neurological diseases. Participants will be asked to complete 7 in-person study visits and monthly remote self-assessment activities. Access to a personal device (computer and/or smartphone or tablet) that is connected to the internet is needed to complete the monthly remote activities.

Individuals who are carriers of ALS causative gene variants have an increased lifetime risk of developing ALS or a related disorder, Frontotemporal Dementia (FTD). We are doing this research to collect a wide range of biofluid samples, clinical information, and other health and wellbeing information to look for measurable differences that will help us understand how and when the body changes in response to ALS causative gene variants.

The primary research element is to determine whether a graft-versus-host disease (GVHD) prophylaxis regimen of post-transplant cyclophosphamide, tacrolimus and MMF will reduce the likelihood of chronic GVHD in patients receiving a standard hematopoietic myeloablative stem cell transplant. The treatment related components of this protocol are established clinical practices. We are looking at cumulative incidence of chronic GVHD requiring systemic immunosuppressive treatment at 1 year post-transplant.

Although allogeneic hematopoietic cell transplant (HCT) is standard treatment for severe aplastic anemia, the use of the lower intensity conditioning drugs with a personalized dosing strategy, low dose total body irradiation (TBI) with dosing based on age and bone marrow abnormalities, and use of the drug cyclophosphamide early after transplant is a newer approach. We are studying whether this new approach is safer and more effective than our previous approach.

This study is about finding out if the study drug, TARPEYO®, can be taken for a longer time (2 years) than the current recommended 9 months, to better help people with primary IgA nephropathy (IgAN).

The purpose of this study is to learn about the safety and effects of pioglitazone and metformin on people and their risk of cancers of the head or neck. We hope to learn more about the potential for pioglitazone and metformin to be used as a way to prevent oral or oropharyngeal cancers in people who are at risk for those cancers. Participants will get both pioglitazone and metformin, as a single pill to be taken at the same time for 12 weeks.

The purpose of this study is to learn the effects, good or bad, of the study drug, vosoritide, for treating children who have hypochondroplasia.

We have determined that the microbes (bacteria) in the colon can play a role in causing and preventing complications of colon surgery. While the surgical bowel prep before surgery eliminates the harmful bacteria, it also eliminates the beneficial bacteria that aid wound healing. The purpose of this study is to determine if we can restore the presence of good bacteria (also known as ‘intestinal microbiota’) in the colon by transplanting them from a healthy donor.

To evaluate the efficacy, safety, and pharmacokinetics of VX-407 in participants with Autosomal Dominant Polycystic Kidney Disease with PKD1 gene variants

The purpose of the study is to determine the safety and effectiveness of a new procedure to treat Mucopolysaccharidosis Type I Hurler-Scheie and Scheie (MPS I). This procedure involves collecting some white blood cells (termed “B cells”) and growing them outside of the body in a laboratory. While the cells are in the lab, the B cells will be changed to produce more of the IDUA that is missing. This process is called “genetic modification.” The newly modified B cells are then infused back into the participant.
