Brief summary
The purpose of this observational study is to evaluate the effectiveness and safety of generic imatinib under usual clinical practice in patients of Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML) patients in chronic phase (CP) in Egypt
Detailed description
An observational, multi-center, prospective cohort study to assess the effectiveness and safety of generic Imatinib (Carcemia®) in patients with Ph+ CML who are newly diagnosed or patients who will be switched from the reference product (Glivec® ) to Carcemia® where treatment will be prescribed by the investigator in accordance with clinical practice where no visits or intervention(s) additional to the daily practice will be performed. Eligible Ph+ CML patients in both cohorts will be followed up for a total of 18 months.
Interventions
Film coated tablet contains 400 mg imatinib (as mesilate)

Eligibility
Inclusion criteria
First cohort (newly diagnosed patients): * Age ≥18 years * Newly diagnosed patients with Ph+ CML in CP, with or without the presence of other cytogenetic abnormalities at the time of diagnosis * Treatment naïve patients with confirmed diagnosis within 3 months of study enrolment * Levels of liver aminotransferases and serum bilirubin ≤ 2 times the upper limit of the normal range, and serum creatinine ≤1.5 times the upper limit of the normal range * Written informed consent Second cohort (switched patients): * Age ≥18 years * Ph+ CML patients in CP currently treated with Glivec®, with or without the presence of other cytogenetic abnormalities at the time of switch * Levels of liver aminotransferases and serum bilirubin ≤ 2 times the upper limit of the normal range and serum creatinine ≤1.5 times the upper limit of the normal range * Written informed consent
Exclusion criteria
* CML in accelerated phase (AP) at enrollment except patients in AP with the presence of other cytogenetic abnormalities at the time of diagnosis * CML in BP at enrollment * Patients who meet any of the contraindications to the administration of the study drug according to the approved Summary of Product Characteristics
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients who achieve and maintain major molecular response (MMR) | 12 months | Major molecular response (MMR) is measured using real-time quantitative polymerase chain reaction (RQ-PCR) test and is defined as BCR-ABL1 ≤ 0.1% |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression free survival (PFS) | 18 months | Proportion of CML patients who will not experience disease progression from enrollment to 18 months study endpoint. |
| Event free survival (EFS) | 18 months | Proportion of CML patients who will not experience event from enrollment to 18 months study endpoint |
| Survival without blastic phase (BP) | 18 months | Proportion of CML patients who will not experience blastic phase (BP) from enrollment to 18 months study endpoint. |
| Overall survival (OS) | 18 months | Proportion of CML patients who will not die till 18 months study endpoint. |
| Incidence of adverse events (AEs) and serious adverse events (SAEs) to generic Imatinib (Carcemia®) | 18 months | Number, type, severity and frequency of adverse events (AEs), serious AEs (SAEs), and clinically relevant changes in laboratory tests according to laboratory reference ranges |
| Complete molecular response (CMR) | 12 months | Proportion of CML patients who will achieve undetectable BCR-ABL mRNA transcripts by RQ-PCR test in two consecutive blood samples of adequate quality. |
| Health-Related Quality of Life (HRQoL) | 18 months | Mean change in Health-Related Quality of Life (HRQoL) utilizing EORTC QOLCML24 questionnaire throughout treatment visits |
| Treatment compliance on generic Imatinib | 18 months | Evaluated by identifying the frequency of not taking the medications as prescribed and the reasons. The decision on non-compliance is based on the treating physician's judgment. |
| Complete cytogenetic response (CCgR) | 12 months | Proportion of CML patients who will achieve no Ph+ metaphases at 12 months study endpoint by conventional cytogenetics and/or FISH test. |
