  1. 1. Modelling of drug-effect on time-varying biomarkers

    Författare :Felix Held; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cortisol; TNFα; hierarchical modelling; turnover model; pharmacokinetic pharmacodynamic modelling; cortisol TNFα hierarchical modelling turnover model pharmacokinetic pharmacodynamic modelling;

    Sammanfattning : Model-based quantification of drug effect is an efficient tool during pre-clinical and clinical phases of drug trials. Mathematical modelling can lead to improved understanding of the underlying biological mechanisms, help in finding shortcomings of experimental design and suggest improvements, or be an effective tool in simulation-based analyses.

  3. 2. Models for Ordered Categorical Pharmacodynamic Data

    Författare :Per-Henrik Zingmark; Mats O Karlsson; E. Niclas Jonsson; France Mentré; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Pharmacodynamic; Modelling; Categorical data; NONMEM; Proportional odds model; Markov model; Differential drug effect model; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI;

    Sammanfattning : In drug development clinical trials are designed to investigate whether a new treatment is safe and has the desired effect on the disease in the target patient population. Categorical endpoints, for example different ranking scales or grading of adverse events, are commonly used to measure effects in the trials. LÄS MER

  4. 3. Application of new methodology for preclinical development of anticancer drugs : With special focus on camptothecin derivatives and the cyanoguanidine CHS 828

    Författare :Elin Jonsson; Uppsala universitet; []
    Nyckelord :Medical sciences; drug development; hollow-fiber model; FMCA; human tumour cell; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; klinisk farmakologi; Clinical Pharmacology;

    Sammanfattning : This work describes the development and evaluation of new methods for preclinical anticancer drug development. The methods were specifically applied to study camptothecin analogues and the new compound CHS 828 (N-(4-chlorophenoxyhexyl)-N'-cyano-N"-4-pyridylguanidine) currently in early clinical trials.

  5. 4. Mixed Effects Modeling of Deterministic and Stochastic Dynamical Systems - Methods and Applications in Drug Development

    Författare :Jacob Leander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pharmacometrics; pharmacokinetics; mixed effects; drug development; pharmacodynamics; parameter estimation; time-to-event; mathematical modeling; dynamical systems;

    Sammanfattning : Mathematical models based on ordinary differential equations (ODEs) are commonly used for describing the evolution of a system over time. In drug development, pharmacokinetic (PK) and pharmacodynamic (PD) models are used to characterize the exposure and effect of drugs. LÄS MER

  7. 5. On enhancement of bone formation using local drug delivery systems

    Författare :Ali Alenezi; Ann Wennerberg; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone formation; local drug delivery systems;

    Sammanfattning : Introduction: Despite that many reports have confirmed the long-term clinical success rates associated with implant treatment, implant failure to achieve and maintain osseointegration still occurs in many cases. Local and sustained drug release at the bone-implant interface is one of the strategies that have been suggested to improve the osseointegration. LÄS MER
