Long-acting Low Dose Ropeginterferon for Chronic Myeloid Leukemia Treated With Bosutinib From Diagnosis

Phase 2
Recruiting
Conditions
Chronic Myeloid Leukemia
Interventions
Drug: Ropeginterferon
Registration Number
NCT03831776
Lead Sponsor
St. Olavs Hospital
Brief Summary

To study the efficacy and safety of combination of Ro-Peg-interferon-α2b (RoPegIFN) with Bosutinib (BOS) in comparison to BOS monotherapy, as frontline therapy for newly diagnosed chronic myeloid leukemia patients, and to estimate efficacy of the addition of RoPegIFN to BOS in terms of deep molecular response with the aim of increasing the proportion of patients who may achieve treatment free remission. (NCMLSG study #NordCML012)

Primary Outcome Measures
NameTimeMethod
Rate of molecular response 4 (MR4)12 months

Molecular response 4 (MR4) is defined by either a positive BCR-ABL/ABL ratio ≤ 0.01% on the international scale (IS) or by undetectable BCR-ABL with the analysis of at least 10000 copies of ABL or 24000 copies of GUS (according to the ELN recommendations by N. Cross et al., Leukemia 2015)

Secondary Outcome Measures
NameTimeMethod
Dose intensity of RoPegIFN and Bosutinib2 years
Rate of molecular response MR2, MR3, MR4, MR4.5 from 1 month up to 24 months and every 6 months thereafter2 years
Cumulative incidence of molecular response MR3, MR4, MR4.52 years
Rate of complete cytogenetic response (CCyR) up to 12 months12 months
Rate of undetectable molecular response for patients who achieved molecular response MR4 and MR4.52 years
Time to and duration of CCyR, MR3, MR4, MR4.52 years
proportion of patients eligible for randomization after 3 months of Bosutinib3 months
rate and characteristics of severe adverse events (SAE)2 years

type and grade according to the NCI CTCAE v4.03

Cumulative incidence of discontinuation of the therapies, incl. reasons for discontinuation2 years
Quality of life assessment by QLQC30 questionnaire up to 6 years at key time point (Day 1, month 3, month 6, month 12, month 24, month 48, month 54, month 72)6 years
Quality of life assessment by CML24 questionnaire up to 6 years at key time point (Day 1, month 3, month 6, month 12, month 24, month 48, month 54, month 72)6 years
The proportion of patients achieving a durable deep molecular response and being eligible for treatment discontinuation at month 484 years

Sustained deep molecular response (MR) criteria will be defined according updated data and ELN guidelines before the first patient will achieve month 48 (at least a MR4 over a 12 months period and confirmed on the last centralized measurement at month 48
