Nilotinib + Pegylated Interferon Alpha 2a for Untreated Chronic Phase Chronic Myelogenous Leukemia

"Phase II Multicenter Study Evaluating the Efficacy and the Safety of a Combination of Nilotinib Plus Pegylated Interferon Alpha 2a for de Novo Chronic Phase Chronic Myelogenous Leukemia Patients"

The aim of this study is to demonstrate the safety and the efficacy of a combination of 2 treatments shown to have some efficacy in Chronic Phase Chronic Myelogenous Leukemia (CP CML) separately, but that have never been combined to date, and this combination is expected to substantially increase the molecular response rates.

Inclusion Criteria:

  • Total Bilirubin < 1.5xUpper Normal Range (UNR).
  • Aspartate Amino Transferase (ASAT) and Alanine Amino Transferase (ALAT) < 2.5xUNR.
  • Alkaline phosphatase ≤ 2.5xUNR
  • Amylase and lipase ≤ 1.5xUNR.
  • Creatininemia < 1.5xUNR.

• Biological blood standards :

  • Potassium ≥ Lower Normal Range (LNR)
  • Magnesium ≥ LNR.
  • Phosphorus ≥ LNR
  • Calcium ≥ LNR.

• Negative pregnancy test within the last 7 days for women with childbearing potential.

• Informed consent signed up

• Compliance to tretament ensured,

• Valid social insurance
