NCT01577992
Multiple system atrophy (MSA) is a sporadic neurodegenerative disorder. MSA is dominated by autonomic/urogenital failure which may be associated with either Parkinsonism (MSA-P subtype) or with cerebellar ataxia (MSA-C subtype). The prognostic of this disease is bad because it ended with the patient's death few years later. No neuroprotective treatment has shown a real efficacy. 50% of patients suffering of MSA frequently experienced painful sensation. The origin of this pain is unknown. In Parkinson disease (PD) ; arguments suggest the implication of dopamine neuromediator pathway in integration and modulation of pain. Several studies suggest the existence of various influences with dopamine implication in the appearance of painful sensation and that would be inhibitory. That's why observed painful symptoms in MSA and PD could be due to a decrease of pain appearance threshold, secondary to a lost of control of sensitizes centres, to Parkinson control. It is interesting to determine if MSA as PD is responsible for a decrease of pain threshold and to characterise the levodopa effect on the patient's pain threshold. Better physiopathology knowledge of pain in MSA is necessary to improve the therapeutic care. Because the efficacy of others treatments is low, it's important to improve the research for a better comfort of patients with a better understanding, analysing and treating of the pain.

NCT07230834
This study is researching an experimental drug called pozelimab (called "study drug"). The study is focused on people with a condition where certain parts of the eye's retina stop working over time, which can make it harder to see. This is called geographic atrophy (GA). The aim of the study is to see how safe and tolerable the study drug is when used as an injection in the eye. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood and the fluid in the eye at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
NCT03495700
The L-PRF block is a combination of bone substitute with L-PRF. The use of a L-PRF block in bone augmentation therapies could enhance and improve bone regeneration. The primary objective of this study is to evaluate if the use of autologous leukocytes and platelet rich fibrin accelerate and promotes bone regeneration in the sinus in comparison with the standard sinus lift procedure procedure.
NCT07543003
Active-NBS is a study to evaluate the muscle development of patients with spinal muscular atrophy (SMA) who are diagnosed at birth. Medicines have become available in the last decade, and many patients are treated very early. Treatments are most effective if used before the patient develops symptoms. However, some patients may show symptoms by the time they receive treatment. This means that even with early diagnosis, they might still develop muscle weakness despite treatment. The investigators want to see when the movements of patients diagnosed at birth differ from normal development. This information will help identify the best time to give additional medicines currently being developed to support the muscle. The investigators will track the progress of up to 60 patients over a maximum of 30 months using wearable technologies which are worn at home. The investigators aim to validate their outcomes for use in this age group. The wearable devices are called Syde and Motor Assessment of an Infant in a Jumpsuit (MAIJU). They will be worn at regular intervals during the study and will not involve extra hospital visits for patients. The study will also recruit up to 30 healthy control participants and follow them for up to 30 months. This will help define normal development with use of the Syde device. Active-NBS will be conducted in the UK and internationally using a federated data model. Collaborative sites will collect harmonised data in accordance with the Active-NBS protocol, with data integration and oversight managed by the University of Oxford. International sites may contact the Oxford study team to establish collaboration.
NCT07444476
In this study, researchers will learn more about the effects and safety of BIIB115, also known as salanersen. Specifically, researchers will learn more about how salanersen works in individuals with SMA who are between the ages of 15 and 60 years old. In most people living with SMA, changes to or a lack of a gene called survival motor neuron 1 (SMN1) - often referred to as gene mutations or variants - affect how this gene works. As a result, their bodies produce less SMN protein. Without enough of this protein, motor neurons and muscles cannot work properly. There is a similar gene called SMN2 that produces SMN protein, but it usually does not produce enough SMN protein on its own to make up for the changes in the SMN1 gene. Salanersen is a drug designed to help the SMN2 gene to make more working SMN protein. In this study, there will be 2 groups of participants: a group who has never received treatment for SMA before joining this study, and a group who has been treated with risdiplam, an approved drug for SMA . Those participants must not have received any other SMA treatments before and will need to stop their risdiplam treatment for the duration of the study. The main goal of this study is to learn more about how salanersen affects the participants' motor function. Researchers will use different tests and questionnaires to learn if motor function is changing over the study duration. The main question researchers want to answer in this study is: • For the group who has never been treated for SMA, how much do scores on the HFMSE movement test change at 12 months compared to the beginning of the study? The Hammersmith Functional Motor Scale - Expanded (HFMSE) has 33 activities that are scored which include sitting, lying down, walking, jumping, and more. Researchers will also learn more about: * The effects on participants' motor function and how well their nerves and muscles function. * The effects on participants' overall sense of change and how they perform daily activities. * How many participants have adverse events or serious adverse events. Adverse events are health problems that may or may not be caused by the study drug. * How much salanersen gets into the fluid surrounding the brain and spinal cord. * How much salanersen gets into the blood. This study will be done as follows: * First, participants will be screened to check if they can join the study. The screening period may be up to 4 weeks. * This is an "open-label" study. This is a study in which the participants, study doctor, and site staff will know that participants are receiving salanersen. * All participants will receive salanersen through an intrathecal injection, or one that is given into the fluid surrounding the brain and spinal cord. * Participants will receive salanersen once every year for a total of 5 times throughout the study. * Including screening, participants will have 17 study visits and 9 telephone calls during this study, which will last up to 61 months in total.

NCT07529041
The goal of this Proof of Concept Feasibility Study is to improve the fixation stability in patients with fixation loss due to blindness or central vision loss using a patented acoustic real-time feedback device. The main questions it aims to answer are: 1. Fixation guidance - can real-time acoustic biofeedback improve the fixation in healthy patients as well as patients with fixation loss? 2. Optimization of fixation guidance - testing of different stimuli to optimize an acoustic training protocol. 3. Optimization of imaging acquisition - testing improvement of both imaging quality and acquisition time using the acoustic feedback tool. For the proof-of-concept-study, patients are asked to fixate on a target point in a darkened room and keep up the fixation. We record patients eye movements with near-infrared-lighting and a camera. Fixation is tested in three conditions - visual target only, auditory feedback only, and visual target followed by auditory feedback. In between each set of trials, patients are asked to rate their subjective exhaustion on a Likert scale. At the end of each recording session, patients are handed a questionnaire for feedback on our proof-of-concept study and device settings. An ethics-approved extension phase is planned to further optimize device parameters and assess performance in a clinical setting.

NCT07002931
Background: Reconstruction of the deficient maxillary ridge in three dimensions is crucial for the successful placement of implants. Prebent titanium meshes are an established modality for GBR, while patient-specific PEEK meshes have recently emerged with some possible advantages over the former. This study compared the effectiveness of these two modalities for bone augmentation. Materials and Methods: 14 patients with 28 augmented sites in the maxillary ridges of primarily horizontal bone deficiencies, often associated with minor vertical components, were randomly assigned to two groups. The control group (n=7) was augmented with a prebent titanium mesh, while the study group (n=7) was augmented with a customized milled PEEK mesh. Both were grafted with a mixture of autogenous bone and xenograft. The primary outcome was horizontal bone gain. Secondary outcomes included vertical bone gain, gained bone volume, and graft resorption. These parameters were assessed by CBCT preoperatively, immediately postoperatively, and at 6 months before implant placement.
