Imatinib tablet cut with a pill splitter
The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended granting marketing authorization for Imatinib Teva B.V., a generic of Glivec.
The recommendation is that Imatinib Teva B.V. be approved to treat chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), hypereosinophilic syndrome (HES), chronic eosinophilic leukemia (CEL), myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPNs), gastrointestinal stromal tumors (GIST), and dermatofibrosarcoma protuberans (DFSP).
The European Commission typically adheres to the CHMP’s recommendations and delivers its final decision within 67 days of the CHMP’s recommendation.
The European Commission’s decision will be applicable to the entire European Economic Area—all member states of the European Union plus Iceland, Liechtenstein, and Norway.
If approved, Imatinib Teva B.V. will be available as capsules and film-coated tablets (100 mg and 400 mg). And it will be authorized:
- As monotherapy for pediatric patients with newly diagnosed, Philadelphia-chromosome-positive (Ph+) CML for whom bone marrow transplant is not considered the first line of treatment.
- As monotherapy for pediatric patients with Ph+ CML in chronic phase after failure of interferon-alpha therapy or in accelerated phase or blast crisis.
- As monotherapy for adults with Ph+ CML in blast crisis.
- Integrated with chemotherapy to treat adult and pediatric patients with newly diagnosed, Ph+ ALL.
- As monotherapy for adults with relapsed or refractory Ph+ ALL.
- As monotherapy for adults with MDS/MPNs associated with platelet-derived growth factor receptor gene re-arrangements.
- As monotherapy for adults with advanced HES and/or CEL with FIP1L1-PDGFRα rearrangement.
- As monotherapy for adults with Kit- (CD117-) positive, unresectable and/or metastatic malignant GISTs.
- For the adjuvant treatment of adults who are at significant risk of relapse following resection of Kit-positive GIST. Patients who have a low or very low risk of recurrence should not receive adjuvant treatment.
- As monotherapy for adults with unresectable DFSP and adults with recurrent and/or metastatic DFSP who are not eligible for surgery.
The CHMP said studies have demonstrated the satisfactory quality of Imatinib Teva B.V. and its bioequivalence to the reference product, Glivec.
In adult and pediatric patients, the effectiveness of imatinib is based on:
- Overall hematologic and cytogenetic response rates and progression-free survival in CML
- Hematologic and cytogenetic response rates in Ph+ ALL and MDS/MPNs
- Hematologic response rates in HES/CEL
- Objective response rates in adults with unresectable and/or metastatic GIST and DFSP
- Recurrence-free survival in adjuvant GIST.
The experience with imatinib in patients with MDS/MPNs associated with PDGFR gene re-arrangements is very limited. There are no controlled trials demonstrating a clinical benefit or increased survival for these diseases.
