PharmGKB contains no dosing guidelines for this . To report known genotype-based dosing guidelines, or if you are interested in developing guidelines, click here.
PharmGKB annotates drug labels containing pharmacogenetic information approved by the US Food and Drug Administration (FDA), European Medicines Agency (EMA) and the Pharmaceuticals and Medical Devices Agency, Japan (PMDA). PharmGKB annotations provide a brief summary of the PGx in the label, an excerpt from the label and a downloadable highlighted label PDF file. A list of genes and phenotypes found within the label is mapped to label section headers and listed at the end of each annotation. PharmGKB also attempts to interpret the level of action implied in each label with the "PGx Level" tag.
- FDA Information is gathered from the FDA's "Table of Pharmacogenomic Biomarkers in Drug Labels" and from FDA-approved labels brought to our attention. Please note that drugs may be removed from or added to the FDA's Table without our knowledge. We periodically check the Table for changes and update PharmGKB accordingly. Drugs listed on the Table to our knowledge are tagged with the Biomarker icon. A drug label that has been removed from the Table will not have the Biomarker icon but will continue to have an annotation on PharmGKB stating the label has been removed from the FDA's Table. We acquire label PDF files from DailyMed.
- EMA European Public Assessment Reports (EPARs) that contain PGx information were identified from [Article:24433361] and also by searching for drugs for which we have PGx-containing FDA drug labels.
- PMDA Japanese drug label annotation information is sourced from Shimazawa and Ikeda (2013), whose paper provided translations of the pharmacogenetic information contained in PMDA package inserts. The authors selected which PMDA package inserts to examine for PGx information based the FDA's "Table of Pharmacogenomic Biomarkers in Drug Labels".
We welcome any information regarding drug labels containing PGx information approved by the FDA, EMA, PMDA or other Medicine Agencies around the world - please contact feedback.
The EMA European Public Assessment Report (EPAR) for imatinib (Glivec) contains pharmacogenetic information regarding the indication of the drug in patients with tumors positive for biomarkers including KIT (CD117), BCR-ABL (Philadelphia chromosome), PDGFR and FIP1L1-PDGFRalpha rearrangements.
Excerpt from the imatinib (Glivec) EPAR:
Glivec is indicated for the treatment of
- adult and paediatric patients with newly diagnosed Philadelphia chromosome (bcr-abl) positive (Ph+) chronic myeloid leukaemia (CML) for whom bone marrow transplantation is not considered as the first line of treatment.
- adult and paediatric patients with Ph+ CML in chronic phase after failure of interferon-alpha therapy, or in accelerated phase or blast crisis.
- adult patients with newly diagnosed Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph+ ALL) integrated with chemotherapy.
- adult patients with relapsed or refractory Ph+ ALL as monotherapy.
- adult patients with myelodysplastic/myeloproliferative diseases (MDS/MPD) associated with platelet-derived growth factor receptor (PDGFR) gene re-arrangements.
- adult patients with advanced hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL) with FIP1L1-PDGFR rearrangement.
Glivec is indicated for
- the treatment of adult patients with Kit (CD 117) positive unresectable and/or metastatic malignant gastrointestinal stromal tumours (GIST).
- the adjuvant treatment of adult patients who are at significant risk of relapse following resection of Kit (CD117)-positive GIST. Patients who have a low or very low risk of recurrence should not receive adjuvant treatment.
This information is highlighted in the following sections:
Therapeutic indications, posology and method of administration, pharmacodynamic properties, package leaflet: information for the user.
The label also states that caution be taken when imatinib is taken concomittantly with CYP3A4 inhibitors and CYP3A4 inducers should be avoided.
For the complete drug label text with sections containing pharmacogenetic information highlighted, see the imatinib EMA drug label.

Disclaimer: The PharmGKB's clinical annotations reflect expert consensus based on clinical evidence and peer-reviewed literature available at the time they are written and are intended only to assist clinicians in decision-making and to identify questions for further research. New evidence may have emerged since the time an annotation was submitted to the PharmGKB.
