    • Introduction: Development of a selective and specific high affinity PET tracer, [C-11]UCB-A, for the in vivo study of SV2A expression in humans. Radiochemistry and preclinical studies in rats and pigs including development of a tracer kinetic model to determine V-T. A method for the measurement of percent intact tracer in plasma was developed and the radiation dosimetry was determined in rats. Results: 3-5 GBq of [C-11]UCB-A could be produced with radiochemical purity exceeding 98% with a specific radioactivity of around 65 GBq/mu mol. In vitro binding showed high selective binding towards SV2A. [C-11]UCB-A displayed a dose-dependent and reversible binding to SV2A as measured with PET in rats and pigs and the V-T could be determined by Logan analysis. The dosimetry was favorable and low enough to allow multiple administrations of [C-11]UCB-A to healthy volunteers, and the metabolite analysis showed no sign of labeled metabolites in brain. Conclusions: We have developed the novel PET tracer, [C-11]UCB-A, that can be used to measure SV2A expression in vivo. The dosimetry allows up to 5 administrations of 400 MBq of [C-11]UCB-A in humans. Apart from measuring drug occupancy, as we have shown, the tracer can potentially be used to compare SV2A expression between individuals because of the rather narrow range of baseline V-T values. This will have to be further validated in human studies.

  • Second international consensus report on gaps and opportunities for the clinical translation of precision diabetes medicine
  • 2023
  • Ingår i: Nature Medicine. - 1546-170X. ; 29:10, s. 2438-2457
  • Forskningsöversikt (refereegranskat)abstract
    • Precision medicine is part of the logical evolution of contemporary evidence-based medicine that seeks to reduce errors and optimize outcomes when making medical decisions and health recommendations. Diabetes affects hundreds of millions of people worldwide, many of whom will develop life-threatening complications and die prematurely. Precision medicine can potentially address this enormous problem by accounting for heterogeneity in the etiology, clinical presentation and pathogenesis of common forms of diabetes and risks of complications. This second international consensus report on precision diabetes medicine summarizes the findings from a systematic evidence review across the key pillars of precision medicine (prevention, diagnosis, treatment, prognosis) in four recognized forms of diabetes (monogenic, gestational, type 1, type 2). These reviews address key questions about the translation of precision medicine research into practice. Although not complete, owing to the vast literature on this topic, they revealed opportunities for the immediate or near-term clinical implementation of precision diabetes medicine; furthermore, we expose important gaps in knowledge, focusing on the need to obtain new clinically relevant evidence. Gaps include the need for common standards for clinical readiness, including consideration of cost-effectiveness, health equity, predictive accuracy, liability and accessibility. Key milestones are outlined for the broad clinical implementation of precision diabetes medicine.
