Immunotherapy has transformed the treatment of cancer, yet many patients do not have response or lasting benefit. Strategies to overcome resistance remain of crucial importance. Oncolytic viruses offer a promising approach, with the unique ability to selectively replicate within (and to destroy) cancer cells, remodel the immunosuppressive tumour microenvironment, and stimulate antitumour immunity. Interest in the potential of oncolytic viruses has grown steadily over the past two decades, fuelled by advances in cancer immunology and viral engineering. However, clinical translation has not kept pace, and although a plethora of promising new constructs have entered clinical testing, several barriers continue to restrict widespread clinical implementation. This Therapeutics paper highlights key milestones in oncolytic virus clinical development, discusses the challenges that remain, and, through clinical reflection, considers how future research might be streamlined to achieve meaningful benefit for patients.

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of epilepsy-related mortality. Generalised-particularly nocturnal-convulsive seizures, longstanding epilepsy, and solitary living have been identified retrospectively as risk factors. No definitive electroclinical biomarkers have been prospectively ascertained. This study aimed to identify SUDEP risk markers using multimodality data with long-term follow-up.

Current treatment options for youth-onset type 2 diabetes are limited and have demonstrated lower glycaemic efficacy than those for adult-onset type 2 diabetes. We aimed to assess the safety and efficacy of tirzepatide, a glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist, compared with placebo in youth-onset type 2 diabetes.
