  1. 11. Pharmacokinetic-Pharmacodynamic Evaluations and Experimental Design Recommendations for Preclinical Studies of Anti-tuberculosis Drugs

    Författare :Chunli Chen; Ulrika Simonsson; Mats Karlsson; Sebastian Wicha; Bernd Meibohm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tuberculosis; pharmacokinetics; pharmacodynamics; pharmacometrics; the Multistate Tuberculosis Pharmacometric model; the General Pharmacodynamic Interaction model; optimized design; rifampicin; isoniazid; ethambutol; pyrazinamide; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Tuberculosis is an ancient infectious disease and a leading cause of death globally. Preclinical research is important for defining drugs and regimens which should be carried forward to human studies. LÄS MER

  2. 12. Semi-mechanistic models of glucose homeostasis and disease progression in type 2 diabetes

    Författare :Steve Choy; Maria Kjellsson; Mats Karlsson; Willem de Winter; Andrea Mari; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacokinetics; pharmacodynamics; pharmacometrics; glucose homeostasis; insulin; type 2 diabetes; obesity; weight; visceral adipose tissue; HbA1c; non-linear mixed effects; modelling; disease progression; ZDSD rats; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Type 2 diabetes mellitus (T2DM) is a metabolic disorder characterized by consistently high blood glucose, resulting from a combination of insulin resistance and reduced capacity of β-cells to secret insulin. While the exact causes of T2DM is yet unknown, obesity is known to be a major risk factor as well as co-morbidity for T2DM. LÄS MER

  3. 13. Novel Pharmacometric Methods for Informed Tuberculosis Drug Development

    Författare :Oskar Clewe; Ulrika S.H. Simonsson; Mats O. Karlsson; Piet van der Graaf; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacokinetics; pharmacodynamics; PKPD; pharmacometric; nonlinear mixed-effects models; multistate tuberculosis pharmacometric model; general pharmacodynamic interaction model; general pulmonary distribution model; tuberculosis; rifampicin; isoniazid; ethambutol; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : With approximately nine million new cases and the attributable cause of death of an estimated two millions people every year there is an urgent need for new and effective drugs and treatment regimens targeting tuberculosis. The tuberculosis drug development pathway is however not ideal, containing non-predictive model systems and unanswered questions that may increase the risk of failure during late-phase drug development.

  4. 14. Translational Tumor Drug Delivery : Doxorubicin formulation performance, intracellular uptake and molecular diffusion

    Författare :Oliver Degerstedt; Hans Lennernäs; Erik Sjögren; Per Hansson; Jessica Rosenholm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; doxorubicin; drug diffusion; cellular uptake; drug delivery; PBPK modelling; hepatocellular carcinoma; emulsion; IC50; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Globally, hepatocellular carcinoma (HCC) is the most common form of liver cancer and a leading cause of cancer death. One important risk factor is liver cirrhosis and the disease progression is characterized by deposition of extracellular matrix proteins that form a fibrous network, which increases liver stiffness and may limit the effectiveness of different treatment strategies.

  5. 15. Improved Methods for Pharmacometric Model-Based Decision-Making in Clinical Drug Development

    Författare :Anne-Gaëlle Dosne; Mats O. Karlsson; Rik Schoemaker; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; nonlinear mixed-effects models; confirmatory trials; residual error modeling; parameter uncertainty; sampling importance resampling; model-averaging; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Pharmacometric model-based analysis using nonlinear mixed-effects models (NLMEM) has to date mainly been applied to learning activities in drug development. However, such analyses can also serve as the primary analysis in confirmatory studies, which is expected to bring higher power than traditional analysis methods, among other advantages. LÄS MER
