CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Dose response, Safety, Pharmacokinetic, Pharmacodynamic, Efficacy

To measure cytotoxic drugs, i.e., epirubicin, cyclophosphamide, docetaxel, paclitaxel and doxorubicin, used in routine treatment of breast cancer, and to search for correlations between exposure (AUC) and side effects. The intention is to offer future patients individualized dose adjustments to avoid both over- and under-treatment.

Secondary objectives 14

  1. What correlations can be identified between exposure (AUC) and; hematologic-, liver-, cardiac- and ovarian toxicity?
  2. What correlations can be identified between exposure (AUC) and the patients’ quality of life?
  3. To what extent can genetic predispositions for drug metabolism be used to identify patients at increased risk of under- or overdose?
  4. What correlations can be identified between exposure (AUC) and tumor response in patients receiving neo-adjuvant treatment?
  5. What correlations can be identified between; BMI, age, smoking habits and renal status vs. exposure (AUC)?
  6. Can we identify any relationship between drug exposure (AUC) and; medical care needs, level of employment and time for recovery?
  7. Is there a difference in total and recurrence-free survival, between patients with low compared to medium or high exposure (AUC)?
  8. Is there a difference in the prevalence of severe adverse events in patients’ with high compared to low exposure (AUC)?
  9. Is the dose measurement in capillary blood samples equal or comparable to venous blood samples?
  10. What correlations between exposure (AUC) and circulating extracellular vesicles can be identified?
  11. What correlations between exposure (AUC) and health state utility values can be identified?
  12. Is there a difference in health care costs associated with severe adverse events in patients exhibiting high exposure compared to those with low exposure (AUC)?
  13. Is capillary self-sampling using the True Dose microsampling method feasible and capable of producing analyzable, high-quality samples for TDM in patients with breast cancer?
  14. Is self-collection using the microsampling devices acceptable, usable, and feasible from the participant's perspective?
