Filter by:Xanamem™ is being developed as a potential drug for Alzheimer's disease. This study drug has been designed to change the cortisol levels in the brain. Cortisol is a naturally occurring hormone in the body. It is believed that reducing the level of cortisol will be a benefit in the treatment of Alzheimer's disease. The XanaHES study is testing the safety and tolerability of Xanamem. It is planned to enrol approximately 84 participants, male and female aged from 50 to 75 who are in good health, in the study at 1 centre in Australia. The XanaHES Phase I study is a single-blind study. Subjects will be randomised to receive either 20mg once daily Xanamem or Placebo in cohort 1. Once all subjects have completed the study treatment of 12 weeks, a dose escalation committee will decide if a new cohort, cohort 2, with 30mg once daily vs placebo is started.
This is a pharmacokinetics (PK), open-label, uncontrolled, multicenter phase II trial with age-staggered approach. The primary objective is to evaluate the PK profile of gadopiclenol in plasma following single IV injection of 0.05 mmol/kg body weight (BW) in pediatric population aged from 2 to 17 years undergoing CNS contrast-enhanced MRI (CNS cohort).
The purpose of the study is to induce plasticity in corticospinal-motoneuronal synapses serving an intrinsic hand muscle of the hemiparetic limb in humans with stroke. Neurologically-intact controls are included to verify that an effect was present in absence of stroke. Outcome measures in controls also provide a reference point that help us to understand the size of the effect and mechanisms mediating the effect in the neurologically-intact system.
The assessment of the diameter of the optic nerve sheath (ONSD) using ultrasound can be a very helpful tool in the assessment of increased intracranial pressure in patients operated for urological procedures.
Rapidly accumulating evidence indicates that the central nervous system (CNS) plays a pivotal role in mobility function with age-associated CNS changes strongly contributing to declining mobility. Studies linking the brain to mobility have used anatomical measures like brain volume and white matter integrity, and suggest that damage to the connecting fibers of the brain (white matter) is related to mobility impairment. Unfortunately, age-related structural white matter damage appears irreversible and only indirectly indicates the functional connectivity between brain regions. It is believed that functional brain network analyses have the potential to identify individuals that may benefit from interventions prior to the development of irreversible white matter lesions. The current project will assess both physical and cognitive function and integrate these variables with measures of brain network connectivity.
Gadolinium-enhanced magnetic resonance imaging (MRI) is currently the imaging gold standard to detect active inflammatory lesions in multiple sclerosis (MS) patients. The sensitivity of enhanced MRI to detect active lesions may vary according to the acquisition strategy used (e.g., delay between injection and image acquisition, contrast dose, field strength, and frequency of MRI sampling). Selection of the most appropriate T1-weighted sequence after contrast injection may also influence sensitivity. Several clinical studies performed at 1.5 Tesla have shown that conventional 2D spin-echo (SE) sequences perform better than gradient recalled-echo (GRE) sequences for depicting active MS lesions after gadolinium injection. As relates to MS, 3.0 Tesla systems offer some advantages over lower field strengths, such as higher detection rates for T2 and gadolinium-enhancing brain lesions, an important capability for diagnosing and monitoring MS patients. Recent studies have shown that at 3 Tesla, 3D GRE or 3D fast SE sequences provide higher detection rates for gadolinium-enhancing MS lesions, especially smaller ones, than standard 2D SE, and better suppress artefacts related to vascular pulsation. However, the comparison of the performance of 3D GRE versus 3D SE sequences has not been investigated yet. Objectives To compare the sensitivity of enhancing multiple sclerosis (MS) lesions in gadolinium-enhanced 3D T1-weighted gradient-echo (GRE) and turbo-spin-echo (TSE) sequences.
To investigate the use of balance as a screening tool for Central Sensitization, a condition of the nervous system that is associated with the development and maintenance of chronic pain. This is done by comparing the scores of a gold standard screening tool (the Central Sensitization Inventory) with balance data.
Some cancers can spread, or metastasize, to the brain. When they do, treatment often involves surgery and/or radiation. Optimal treatment of brain metastases would maximize disease control and minimize toxicity (or side effects), and improve the quality of life of patients. A common type of radiation used for brain metastases is called whole brain radiation, which treats not just the cancer that can be seen on scans (i.e., gross disease), but the smaller sites of cancer that may not be visible (i.e. subclinical disease). Fractionation is used to describe repetitive treatments in which small doses (fractions) of a total planned dose are given at separate clinic visits. The most common dosing regimen is 30 Gray (Gy), using 3 Gy per fraction over 10 fractions. Previous studies have suggested that using intensity modulated radiation therapy (IMRT) may be a safer way to deliver higher doses to gross disease and lower doses to the rest of the brain that may contain subclinical disease. This approach may spare the rest of the brain from radiation complications and side effects. The goal of this study is to determine whether using IMRT to treat brain metastases is more effective than current standard whole brain radiation in controlling gross disease and whether patient quality of life and hair loss is improved compared to previous studies using whole brain radiation.
This study aims to evaluate a switch from fixed dose combination (FDC) treatment with ATRIPLA^TM for 12 weeks prior to screening to FDC treatment with Doravirine, Tenofovir, Lamivudine (MK-1439A) in virologically-suppressed, human immunodeficiency virus type 1 (HIV-1)-infected participants. The primary hypothesis is that switching from ATRIPLA^TM to Doravirine, Tenofovir, Lamivudine results in a lower proportion of participants with at least one CNS toxicity of at least Grade 2 intensity at Week 12 than continuation of ATRIPLA^TM treatment.
The purpose of this study is to see if capecitabine can be taken safely with different doses of lapatinib in patients with HER-2 positive breast cancer involving brain (brain metastases) and/or in spinal fluid (leptomeningeal disease).
