Natural History and Biomarkers of Amyotrophic Lateral Sclerosis and Frontotemporal Dementia Caused by the C9ORF72 Gene Mutation

Background: \- Some people have a mutation in the C9ORF72 gene that causes amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD). The mutation causes a small piece of DNA to repeat itself thousands of times. The C9ORF gene mutation mostly occurs in families. In those families, some persons have ALS and others have FTD. Occasionally the C9ORF gene mutation occurs in persons without a family history. Researchers want to understand how this gene causes different diseases. They will study how symptoms caused by the C9ORF gene develop and change over time. They will measure symptoms that occur in ALS and in FTD. In particular, they will measure strength, ability to move, thinking, and memory. They will also see if other tests are associated with progression of disease. These tests, called biomarkers, may help detect or measure C9ORF72 disease in the future. Objectives: \- To understand how symptoms change over time in people with mutations in a gene called C9ORF72, which causes ALS and FTD. Eligibility: \- Adults over age 18 who have this genetic mutation Design: * Participants will have up to 4 in-person visits and 3 telephone interviews over 3 years. Each in-person visit may take place over several days. They may be either inpatient or outpatient visits. * At each visit, participants will undergo a series of brain, language, and behavior tests. These will include: * Magnetic resonance imaging (MRI) of the brain. This uses magnets, radio waves, and computers to produce detailed pictures of the brain. * Collecting spinal fluid. The clinician will make the participant s back numb and then insert a needle to collect fluid. \<TAB\>- Blood samples will be taken. \<TAB\>- Participants will be asked to perform several language and movement tests. \<TAB\>- Small skin samples will be taken on one visit \- Between visits, participants will answer questions about their health over the phone 3 times.

Effect of Terazosin on ATP Levels in People With Amyotrophic Lateral Sclerosis

This will be a single center, randomized, double-blind, placebo-controlled pilot study to assess the safety and tolerability of terazosin (TZ) at a dose of 5 milligrams (mg) per os (PO) daily for patients with amyotrophic lateral sclerosis (ALS). The primary outcome of this study is to determine whether TZ increases adenosine triphosphate (ATP) levels in ALS. The investigators will measure adverse outcomes, safety, and tolerability of taking TZ. Procedures include blood draws, spirometry, fluorodeoxyglucose-positron emission tomography (FDG-PET) scans, questionnaires, and physical examinations. TZ will be titrated up to 5 mg PO daily. This is a pilot study and is not powered to assess efficacy of this medication. The investigators' hope is that this study will guide future studies of this (and similar) medications for the disease modification of ALS. This study also aims to learn more about how patients produce and use energy and if TZ can help to reverse energy deficits that appear in ALS.

A Study to Learn More About the Long-Term Safety of Tofersen (Qalsody) in Chinese Participants With SOD-1 Amyotrophic Lateral Sclerosis (ALS)

In this study, researchers will learn more about the safety of tofersen, also known as Qalsody®. This is a drug available for doctors to prescribe for people with a certain type of amyotrophic lateral sclerosis, also known as ALS. This type is in people who have a mutation in the superoxide dismutase 1 gene, also known as SOD-1. This is known as a "postmarketing" study. In this kind of the study, the goal is to learn more about how a drug works after it has been approved for use in the general public. Tofersen was approved in China in September 2024. The main goal of this study is to collect long-term safety information in Chinese participants with SOD-1 ALS. The main question researchers want to answer in this study is: • How many participants have adverse events (AEs) and serious adverse events (SAEs)? An AE is a health problem that may or may not be caused by a drug during the study. An AE is considered serious when it results in death, is life-threatening, causes lasting problems, or requires hospital care. Researchers will also learn more about : * How the body processes tofersen. * How much tofersen is found in the cerebrospinal fluid (CSF), or the fluid that surrounds the brain and the spinal cord. 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 joining the study, participants will receive the first 3 doses of 100 milligrams (mg) of tofersen about 14 days apart. This will be given through an intrathecal (IT) injection. This means it will be given into the fluid surrounding the spine. * After that, participants will receive 10 more doses every 28 days through IT injections. Participants will have up to 13 total doses of tofersen in this study. * Participants will have up to 15 visits to their study research center. Each participant will be in the study for up to 52 weeks (1 year).

Mechanical Insufflation in the Philadelphia Amyotrophic Lateral Sclerosis Cohort (MI-PALS) Study

The goal of this clinical trial is to learn how doing mechanical insufflation (MI) using a mechanical insufflator-exsufflator (MI-E) device affects breathing in early amyotrophic lateral sclerosis (ALS). This will be a single-center, single-arm study of MI in 20 patients with ALS at Penn. Based on prior research, we believe that 6-months of MI may slow decline in cough strength, measured as peak cough flow (PCF). Participants will perform MI using a device designed for mechanical insufflation-exsufflation (MI-E) known as the BiWaze Cough system. The BiWaze Cough is used for mucus clearance . It is connected to tubing and mouthpiece (or mask). The device will use programmed pressure and timing settings. An insufflation includes inflating the lungs for a maximal size inhalation before exhaling. The daily routine for the device includes 5 sets of 5 insufflations twice daily. Researchers will compare how use of MI in early ALS affects peak cough flow compared to 20 subjects who did not use MI in early ALS.

French-German Cohort Study to Determine Factors Associated With Weight Loss in Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease. Studies have shown the importance of weight loss at the time of diagnosis and during the progression of the disease. However, the pathophysiological mechanisms behind weight loss remain unknown. Identifying these mechanisms could make it possible to propose an effective therapeutic strategy against weight loss for ALS patients, which could improve their survival and quality of life. In this context, the investigators are proposing an innovative multidisciplinary project aimed at structuring a large Franco-German cohort to identify the markers associated with weight loss in ALS. Participants will undergo high quality standard care for ALS patients. In addition, participants will be asked to respond different questionnaires and blood samples will be taken for analysis to identify biological markers.

Oral Intake of Enteral Nutrition Formula Preceding Placement and Feeding Via GTube and Its Impact on Formula Intolerance in pALS

The main objective of the proposed study is to evaluate if oral intake of EN formula preceding Gtube placement will impact tolerance upon placement and feeding via Gtube in pALS. This single arm intervention study all participants will receive the intervention and researchers will utilize validated indicators combined with clinical expertise to assess gastrointestinal symptoms of feeding intolerance before and after the intervention. The main questions this study aims to answer are: 1. Wil participants meeting a greater percentage of their estimated nutritional needs at baseline present a slower disease progression rate and a lower incidence of GI symptoms of feeding intolerance when feeding via Gtube? 2. Will there be significant change in feeding intolerance when oral intake of enteral nutrition formula precedes feeding via Gtube? This proposed study consists of three stages, as follows: 1. Pre-Intervention: The lead in period of one-week preceding intervention phase I will be timed to initiate 3 weeks before the scheduled Gtube placement procedure. Patients will be advised to maintain their usual food and beverage intake. Dietary intake and GI symptoms data will be collected by research personnel. 2. Phase I: Dietary intake data collected from the pre-intervention stage will be averaged and used to determine the number of cartons of enteral nutrition formula needed to meet the participants estimated nutritional needs. For two weeks +- 2 days participants will be directed to drink the number of cartons of a pre-selected enteral nutrition formula to meet their estimated nutritional needs when combined to their current oral dietary intake. A plant based EN formula (Kate Farms 1.4 Standard) commonly prescribed for pALS was selected to be provided to all patients in the study to keep this variable constant. Weekly data collection of dietary intake and GI symptoms will be ongoing. 3. Phase II: At the end of phase I, patients will undergo a Gtube placement at their selected medical facility. For the following two weeks +- 2 days participants will be directed to feed via Gtube the same number of cartons of the enteral nutrition formula used orally on phase I and make no changes to their current oral intake.
