It is well known that substantial interindividual variability of CYP3A4/1A2-phenotype activity is an important contributor to individual differences in the sensitivity to the frequently used tyrosine kinase inhibitors sunitinib and erlotinib. This study tests the potential for CYP-phenotyping to predict individual pharmacology and derive dosing algorithms for more tailored treatment of these drugs.

Condition Intervention Phase
Non Small-cell Lung Cancer Renal-cell Cancer Gastrointestinal Stroma Tumor Drug: Sunitinib Drug: Erlotinib Drug: Midazolam Drug: Caffeine Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Further study details as provided by Markus Joerger, Cantonal Hospital of St. Gallen:

Primary Outcome Measures:
  • Steady-state partial area-under the plasma concentration-time curve over 24 hours (AUC24h) of sunitinib and erlotinib and CYP3A4/1A2-phenotype activity as defined in the protocol [ Time Frame: 2 weeks ]
    Sunitinib or erlotinib area under the concentration-time curve during 24 hours at steady-state conditions, compared with the CYP3A4 or CYP1A2 phenotype activity as assessed by the two probe drugs midazolam (CYP3A4) and/or caffeine (CYP1A2)

Secondary Outcome Measures:
  • Sunitinib and Erlotinib-associated toxicity according to the CTC criteria (v.3.0) [ Time Frame: 12 weeks (end of study) ]
  • Concentrations of Sunitinib, Erlotinib and probe drugs (Midazolam, Caffeine) in whole blood, sampled from patient's dried blood spots (DBS) [ Time Frame: 12 weeks (end of study) ]
    Dried blood spots are a potential alternative to venous blood samples to assess drug exposure in cancer patients.

Enrollment: 54
Study Start Date: January 2012
Study Completion Date: November 2015
Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Sunitinib
    Patients with renal-cell cancer or GIST are receiving conventional treatment with sunitinib (50mg/day for 4 out of 6 weeks)
    Other Name: Sutent
    Drug: Erlotinib
    Patients with non small-cell lung cancer receive conventional treatment with erlotinib 150mg/day.
    Other Name: Tarceva
    Drug: Midazolam
    For phenotyping of CYP3A4, all patients receive one-time midazolam 2mg as a drinking solution at the start of study treatment.
    Other Name: Midazolam drinking solution
    Drug: Caffeine
    For phenotyping of CYP1A2, patients with non small-cell lung cancer receive additionally one-time caffeine 100mg as a tablet.
    Other Name: Coffeinum N 0.2g
