KCL and UCL scientists develop accurate AI brain imaging model for research

Researchers from King’s College London have developed a new artificial intelligence (AI) brain imaging model in collaboration with University College London (UCL) which is realistic and accurate enough to use in medical research. Published in Nature Medicine Intelligence, the three-dimensional, synthetic images of the human brain could help support research to predict, diagnose and treat brain diseases including dementia, stroke and multiple sclerosis. According to Brain Research UK, there are an estimated 11 million people in the UK who are living with a neurological condition. Among the most common are Alzheimer’s disease, epilepsy and stroke. In collaboration with the London Medical Imaging and AI Centre for Value-Based Healthcare and NVIDIA data scientists and engineers, researchers trained the AI model in weeks as opposed to months using the NVIDIA Cambridge-1 supercomputer. The model is able to produce 3D, high-resolution images that have all the characteristics of real human brains, including correct ...

Study reveals genetic variants are more common in Parkinson’s disease patients

A US study supported by the Parkinson’s Foundation has revealed that genetic variants associated with Parkinson’s disease (PD) are more common than researchers previously thought. The PD GENEration study published in the journal Brain has been testing for clinically relevant PD-related genes while providing genetic counselling at no cost for people living with the condition since 2019, and recently reached a recruitment milestone of more than 15,000 patients. PD is a neurodegenerative condition in which parts of the brain become progressively damaged, causing problems such as shaking and stiffness. Results from the first 3.5 years of the study showed that 13% of patients have a genetic form of PD and revealed that positivity rates for a genetic variant were significantly higher for individuals at high risk of developing PD. Those with early-onset PD, high risk-ancestry such as Ashkenazi Jewish, Spanish Basque, or North African Berber, or with first-degree relatives affected ...

First Patient Enrolled in the US Phase 2 Combination Therapy of Akeso’s Ligufalimab with Azacitidine for Myelodysplastic Syndrome

Akeso has announced the completion of the first patient enrollment in the US for the phase II clinical trial of its innovative CD47 monoclonal antibody, ligufalimab (AK117), in combination with azacitidine for patients with newly diagnosed higher-risk myelodysplastic syndrome (HR-MDS). Preliminary studies show that combining AK117 with azacitidine for treating MDS is safe and significantly effective. In response to the urgent need for new therapies among global MDS patients and the evolving market landscape, Akeso has launched an international multicenter Phase II clinical trial. This initiative aims to expedite AK117’s global approval and commercialization process. CD47-targeted drug development for treating MDS shows promising potential. AK117, a next-generation humanized IgG4 anti-CD47 antibody, effectively blocks the CD47-SIRPα interaction to enhance phagocytic activity against tumor cells by phagocytes.

Computational protocol provides cheaper route to manage cholesterol levels

Researchers led by Dr Suman Chakrabarty from S N Bose National Centre for Basic Sciences, Kolkata, an autonomous institute under the Department of Science and Technology, in collaboration with Sarfez Pharmaceuticals, have explored a new frontier in computer-aided drug discovery that can help develop medicines that can prevent harmful protein-protein interactions which can lead to conditions like elevated low-density lipoprotein (LDL) or cholesterol level. Traditionally, scientists have tried to develop small molecules as drugs that would preferentially bind to the protein-protein interaction (PPI) sites and act as competitive inhibitors. However, finding drugs that can effectively block these protein interactions has been difficult because the areas where proteins interact are often large and smooth, with no clear spots for a drug to latch onto. A commonly used alternative approach is to use large peptides or antibodies to inhibit PPIs. But these are often undesirable due to the increased cost, difficulty of ...

FDA approves first Nalmefene Hydrochloride auto-injector to reverse opioid overdose

The US FDA approved Zurnai, the first nalmefene hydrochloride auto-injector for the emergency treatment of known or suspected opioid overdose in adults and pediatric patients 12 years of age and older. The agency approved the first nasal spray formulation of nalmefene in May 2023. Drug overdose persists as a major public health issue in the US, with more than 107,000 reported fatal overdoses occurring in 2023, primarily driven by synthetic opioids like illicit fentanyl. Nalmefene and naloxone are two available options to reverse opioid overdose. The FDA has worked to increase the availability and accessibility of both options to encourage harm reduction and reduce overdose death. Nalmefene is an opioid receptor antagonist which is used to treat acute opioid overdose. If nalmefene is administered quickly, it can reverse the effects of opioid overdose, including respiratory depression, sedation and low blood pressure (hypotension).
