Study Overview
Brief Summary
The investigators recently identified promiscuous HLA-DR-derived epitopes from the human telomerase reverse transcriptase (TERT) called universal cancer peptides (UCP), to study tumor-specific CD4+ T cell responses.
The aim of this prospective preliminary study is to evaluate the presence of UCP-specific Th1 responses in patients in complete remission of CML two years after end of Tyrosine Kinase Inhibitor (TKi) treatments.

Inclusion Criteria
- •For cohort A :
- •patient with chronic myelogenous leukemia in chronic phase in deep molecular response (MR4.0) persistent for 2 years or more after end of TKi treatments
- •patient with total cessation of TKi treatment
- •signed written informed consent
- •For cohort B :
- •patient with chronic myelogenous leukemia in chronic phase, for whom a diagnosis of relapse was increased 1 year or less after stopping treatment with TKIs (inclusion of patient under TKi treatment after relapse is possible).
- •signed written informed consent
Exclusion Criteria
- •(for all patients) :
- •patients under chronic treatment with systemic corticoids or other immunosuppressive drugs (corticoids ≤ 10 mg/day is allowed)
- •active autoimmune diseases, HIV, hepatitis C or B virus
- •patient with any medical or psychiatric condition or disease which would make the patient inappropriate for entry into this study.
