This is a randomized, multiple-dose, open-label, parallel-group study. Subjects will undergo screening evaluations to determine eligibility within 28 days prior to study drug administration. Approximately 280 eligible subjects will be randomized in a 1:1 ratio into 1 of 2 treatment groups. Subjects will be admitted to the clinical facilities the day before dosing (Day 0), and will be randomized and receive the first dosing on Day 1. Subjects will stay at site till Day 2 after PK collection. All subjects will return to the clinical sites at designated study days for dosing, PK sample collections and assigned clinical activities. All subjects randomized to LY03010 treatment group will receive the first dose of 351 mg LY03010 by IM injection on Day 1 in the deltoid muscle, followed by five (5) monthly dosing of 156 mg LY03010 in the gluteal muscle with the last dose on Day 141. All subjects randomized to SUSTENNA treatment group will receive the first dose of 234 mg SUSTENNA by IM injection on Day 1 in the deltoid muscle, and a second IM dose of 156 mg SUSTENNA on Day 8 in the deltoid muscle, followed by five (5) monthly IM dosing of 156 mg of SUSTENNA in the gluteal muscle with the last dose on Day 148. End of Study (EOS) visit for LY03010 treatment group will be on Day 169, 28 days after last dosing day; End of Study for SUSTENNA treatment group will be on Day 176, 28 days after last dosing. At EOS visit, subjects will complete the study after a series of assigned clinical assessments. A 30-day follow up call will be conducted by the clinical research staff to ensure participant's well-being.

Learning a person's name, new words, or simply remembering where the last conversation with a friend was held are examples of associative memory, frequently disturbed in brain pathologies, but also by aging. Although typically dependent on the hippocampus in the brain, a series of findings suggest that associative memory may persist, under certain circumstances, despite hippocampal damage. The ANéRAVIMM project aims to reveal this learning system, its cognitive and cerebral bases, and to evaluate its potential in patients with memory disorders.
This study will compare the VerTouch device to the conventional palpation technique for performing diagnostic and therapeutic neuraxial procedures.
All patients undergoing allogeneic or autologous HSCT at the participating centres will be observed. Once a diagnosis of CNS disorder is made, additional data will be reported for these patients. We will identify clinical and diagnostic characteristics such as cerebrospinal fluid (CSF) and neuroimaging patterns, risk factors, response to treatment (including novel antifungal agents such as isavuconazole) and outcome. In addition, risk factors for CNS disorders after allogeneic and autologous HSCT will be analyzed using a prospectively assessed matched control group. In the future, this study might be the basis for an interventional trial (e.g. using a prophylactic approach).
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear. The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
Autoimmune encephalitis (AE) is caused by abnormal immune response mediated by autoimmune antibodies of patients, which can be detected by a serial of autoimmune antibodies[4,5,6,7]. At present, the traditional infection diagnosis mainly relies on microbial culture method, which has the characteristics of long cycle, high cost, low detection rate and complex detection process. About 30-60% of encephalitis have unknown etiology[2,3]. On the other hand, the diagnosis and classification of noninfectious encephalitis mainly depend on the detection of autoimmune antibodies, the scope of diagnosis and differential diagnosis is limited, and the relationship between autoimmune encephalitis and infection factors is still unclear. Metagenomics sequencing (mNGS) is a new method that does not rely on microbial culture and can directly detect pathogenic nucleic acids. It has the characteristics of fast, accurate, high throughput, no preference for different pathogen detection, and can detect known and unknown pathogens at the same time. Nowadays, mNGS is widely used in the field of pathogen detection.
Central nervous system (CNS) infection is a common nervous system acute and severe disease, mainly manifested as encephalitis, meningitis and meningoencephalitis, but also manifested as brain abscess and brain granuloma et al. The basis for the diagnosis of CNS infection lies in the detection of pathogens from brain parenchyma or cerebellar spinal fluid (CSF). However, CSF is relatively difficult to obtain and the sample size is small, which limits the rapid and definite diagnosis of CNS infection pathogens. In addition, CNS infection usually has non-specific clinical manifestations, so it is difficult to identify the pathogen for about half of CNS infection. Metagenomic next generation sequencing (mNGS) and biochip technology provide new means to identify the pathogens of CNS infection. This study analyzes the incidence and epidemic characteristics of CNS infection in China, to standardize the CSF sample processing process, shorten the detection time, increase the sensitivity and specificity of pathogen detection, reduce the detection cost, identify the common pathogens of CNS infection, and establish a standardized rapid diagnosis system, effective prevention and control system.
This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients who did not respond to induction chemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies have shown that patients with newly-diagnosed localized NGGCT, whose disease responds well to chemotherapy before receiving radiation therapy, are more likely to be free of the disease for a longer time than are patients for whom the chemotherapy does not efficiently eliminate or reduce the size of the tumor. The purpose of this study is to see how well the tumors respond to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dose chemotherapy and a stem cell transplant before RT to the whole brain and spine. Giving treatment based on the response to induction chemotherapy may lower the side effects of radiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.
