Randomized Controlled Trial
Safety and efficacy of MD1003 (high-dose biotin) in patients with progressive multiple sclerosis (SPI2): a randomised, double-blind, placebo-controlled, phase 3 trial.
There is an unmet need to develop therapeutic interventions directed at the neurodegeneration that underlies progression in multiple sclerosis. High-dose, pharmaceutical-grade biotin (MD1003) might enhance neuronal and oligodendrocyte energetics, resulting in improved cell function, repair, or survival. The MS-SPI randomised, double-blind, placebo-controlled study found that MD1003 improved disability outcomes over 12 months in patients with progressive multiple sclerosis. The SPI2 study was designed to assess the safety and efficacy of MD1003 in progressive forms of multiple sclerosis in a larger, more representative patient cohort. ⋯ MedDay Pharmaceuticals.

Randomized Controlled Trial Multicenter Study
Tranexamic acid in patients with intracerebral haemorrhage (STOP-AUST): a multicentre, randomised, placebo-controlled, phase 2 trial.
Despite intracerebral haemorrhage causing 5% of deaths worldwide, few evidence-based therapeutic strategies other than stroke unit care exist. Tranexamic acid decreases haemorrhage in conditions such as acute trauma and menorrhoea. We aimed to assess whether tranexamic acid reduces intracerebral haemorrhage growth in patients with acute intracerebral haemorrhage. ⋯ National Health and Medical Research Council, Royal Melbourne Hospital Foundation.

Review
Neuroinflammation in intracerebral haemorrhage: immunotherapies with potential for translation.
Intracerebral haemorrhage is inadequately controlled by current treatments, requiring new solutions to improve the prognosis. Following the primary injury, a proinflammatory cascade in the perihaematomal region, composed of activated resident microglia and astrocytes and infiltrated leucocytes, propagates neural cell death. ⋯ Potential strategies include controlling excessive harmful neuroinflammation with minocycline, sphingosine-1-phosphate receptor modulators, and statins after a brain haemorrhage. The quick initiation of these drugs, particularly in high systemic doses, could be key to counteracting the evolving secondary injury in people with intracerebral haemorrhage and provides a promising way in which the poor prognosis of intracerebral haemorrhage might one day be counteracted.

Sleep disorders in people with autoimmune encephalitis have received little attention, probably overshadowed by the presence of other neurological and psychiatric symptoms in this group of conditions. However, sleep disorders are frequent, often severe, and usually persist beyond the acute disease stage, interfering with patients' recovery and quality of life. ⋯ In anti-IgLON5 disease, sleep disorders were the core symptoms that led to the description of this disease, whereas in anti-NMDA receptor encephalitis, sleep disorders vary according to the disease stage along with other neuropsychiatric symptoms. Comprehensive, systematic, multicentre studies are needed to characterise sleep disorders and their mechanisms in autoimmune encephalitis.
