Conditions

Summary

This is a single-arm, phase II study to evaluate safety and efficacy of tyrosine kinase inhibitor (TKI) cessation for chronic myeloid leukemia (CML) patients with stable molecular response in a real world population.


Eligibility

Min Age: 18 Years

Inclusion Criteria15

  • Patients who are 18 years or older
  • Patients have a diagnosis of Philadelphia chromosome- or BCR-ABL1-positive CML (as determined by cytogenetics, FISH, or PCR).
  • Prior evidence of a quantifiable BCR-ABL1 transcript by RT-PCR
  • Patients who have been taking TKI for \> 36 months.
  • Patients must have a history of stable molecular response, defined as MR4.5 for ≥24 months, as documented by ≥3 separate tests performed at least three months apart.
  • Patient must have a current status of complete molecular remission (CMR), defined as MR4.5 (per section 5.1), within 30 days of signing consent.
  • ECOG performance status \< 2
  • Patients must have normal marrow function within 30 days of registration, as defined:
  • Absolute Neutrophil Count (ANC) ≥ 1.5 x 10E9/L
  • Hemoglobin ≥ 9.0 g/dL
  • Platelets ≥ 100 x 10E9/L
  • Patients must not have any signs of extramedullary leukemia
  • Patients must have a life expectancy of more than 12 months in the absence of any intervention
  • All participants must be informed of the investigational nature of this study and must sign and give written informed consent
  • Contraception requirements will be as per routine clinical practice.

Exclusion Criteria9

  • Patients who are unable or unwilling to give their consent to participate to the study.
  • Previous or planned allogeneic stem cell transplantation
  • Patients who have pathologies or treatments that are able to enhance the potential relapse risk after stopping Imatinib.
  • Patient has received an investigational agent within last 2 years
  • Atypical BCR-ABL transcript not quantifiable by standard RQ-PCR.
  • Patient cannot have had a known interruption of TKI therapy of greater than 14 consecutive days or for a total of 6 weeks in the six months prior to registration.
  • Any medical condition that, in the opinion of the investigator, would exclude the patient from participating in this study.
  • Active liver disease (e.g., chronic active hepatitis, cirrhosis).
  • Known diagnosis of human immunodeficiency virus (HIV) infection.
