Clinical trial

A Study of Efficacy and Safety of Long-acting Low Dose Ropeginterferon in Patients With Chronic Myeloid Leukemia Treated With Bosutinib From Diagnosis: a Randomized Prospective Trial

Name
BosuPeg TRIAL
Description
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.

Treatment
Bosutinib
Bosutinib, provided by Pfizer, starting dose of 200mg QD and stepwise dose escalation (\> 300 mg/d \> 400 mg/d) during the first three months. A pharmacological study will be performed in the French cohort (BOSUSTEP Substudy). BOS residual plasma concentration (Cmin) will be checked after initiation, before each dose step in the French cohort, and at M3 also for Nordic patients in ancillary studies.
Arms:
Bosutinib monotherapy, Bosutinib-Ropeginterferon combination
Ropeginterferon
Ro-Peg-Interferon α2b will be supplied by AOP Orphan to be administered by subcutaneous injections from prefilled injection pens. RoPegIFN will be given in an open-label fashion. Patients assigned to RoPegIFN will start with 50 μg injected subcutaneously every 14 days, in combination with Bosutinib.
Arms:
Bosutinib-Ropeginterferon combination
