In patients with Philadelphia chromosome–positive chronic myeloid leukemia (Ph+ CML)

Prognostic value for your patients1,2

International Scale (IS) RQ-PCR testing is associated with clinically significant results1-3

  • IS RQ-PCR is preferred over cytogenetics to monitor response to TKI therapy4
    • FISH is not recommended to monitor response4
    • IS RQ-PCR can identify patients without early response and may be used to predict survival and guide subsequent therapy1

Early molecular response can be assessed using an IS-standardized RQ-PCR assay1,2,4

Early molecular response (≤10% IS BCR-ABL mRNA at 3 months) may predict long-term survival1

  • Patients who reach early molecular milestones are more likely to achieve and maintain deep molecular responses1
