Chronic Myeloid Leukemia (CML)DiP-in-CMLNCT07158294
Identification of BCR::ABL1 Mutations by Digital PCR in CML
A study testing Peripheral blood withdrawal for BCR::ABL1 mutations testing in people with Chronic Myeloid Leukemia (CML), run by Gruppo Italiano Malattie EMatologiche dell'Adulto.
Trial summary
The goal of this study is to asses the ability of digital PCR (ddPCR) to detect actionable mutations in adult CML patients with failure of TKI therapy. The main objective of the study is it aims to answer is to assess whether ddPCR is at least as effective as NGS in detecting actionable (2GTKI-resistant) mutations. Read more about this study

About this study
Official title: Digital PCR for Deep Sensitivity BCR::ABL1 Mutation Screening in CML
The goal of this study is to asses the ability of digital PCR (ddPCR) to detect actionable mutations in adult CML patients with failure of TKI therapy. The main objective of the study is it aims to answer is to assess whether ddPCR is at least as effective as NGS in detecting actionable (2GTKI-resistant) mutations.
To accomplish this aim, samples of participants treated according to clinical practice, will be taken and analyzed for the presence of BCR::ABL1 KD mutations by ddPCR.
Read the detailed description
This is a multicenter biological study addressing the efficiency of ddPCR in detecting actionable mutations in patients with failure of TKI therapy. The study will involve 4 reference laboratories for BCR::ABL1 KD mutation testing Italian hematological centers enrolling patients and collecting samples for analysis.
Peripheral blood samples taken from patients treated according to clinical practice with resistance to imatinib or 2GTKI therapy according to the ELN recommendations will be shipped to one of the reference laboratories and analyzed by ddPCR using Bio-Rad ADS assays and reagents. Samples will be analyzed in batches of suitable size. ddPCR results will be compared with NGS results generated by reference laboratories belonging to LabNet CML network . In patients positive for mutations below 20% by ddPCR (low level mutations) peripheral blood sample(s) will be collected every 3 months at subsequent follow-up visits to monitor the kinetics of mutations in relation to therapy continuation or change.
No modification of TKI type or TKI dose will be performed on the basis of ddPCR results.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mutations detected by ddPCR
The rate of actionable (2GTKI-resistant) mutations detectable by ddPCR as compared to NGS in patients with failure of TKI therapy according to the current (2020) ELN recommendations.
Measured: At enrollment
