Clinical Trial 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)

• Inability to freely provide consent through judiciary or administrative condition.

• Ongoing participation to another clinical investigational study.

• Medical history and concurrent diseases: a) Hypersensitivity to any of the excipients of BOS or RoPegIFN, b) Prior treatment with Interferon-a, contraindication to interferon-a, c) Autoimmune disorder, concomitant immunosuppressive treatment or corticosteroids, d) Pre-existing thyroid disease unless controlled with conventional treatment, auto-immune thyroiditis, e) Chronic liver disease, f) Prior or ongoing severe psychiatric disease, g) HIV positivity, chronic hepatitis B or C, h) Uncontrolled or severe cardiac (NYHA Class III or IV) or pulmonary disease, echocardiography with LVF < 45% or LLN, peak velocity of tricuspid regurgitant flow > 2,8 m/s, pulmonary arterial hypertension (PAH), QTc>450 ms (by Barrets correction)

• Other malignant disease during the last 5 years prior to the inclusion except non-melanoma skin carcinoma or carcinoma in situ of the cervix,

• History of significant bleeding disorder unrelated to CML or diagnosed congenital bleeding disorder,

• Subjects with an uncontrolled undercurrent illness or any concurrent condition that, in the investigator's opinion, would jeopardize the safety of the subject or compliance with the protocol.

• Prohibited treatments and/or therapies: strong inhibitors/inducers of the CYP 3A4,

• History / any condition for poor compliance to medical treatment.

Intervention

Drug:
• 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.
• Ropeginterferon
Ro-Peg-Interferon a2b 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.
