Nilotinib ± Peg-IFN for First Line Chronic Phase CML Patients (PETALs)

September 27, 2025 updated by: Hospices Civils de Lyon

Randomized Multicenter Phase III Study Comparing the Rate of Molecular Response 4.5 at 12 Months in Newly Diagnosed Philadelphia Positive Chronic Phase Chronic Myelogenous Leukemia Patients Receiving Either Frontline Nilotinib 600 mg Daily or Nilotinib 600 mg Daily Combined to Pegylated Interferon-alfa 2a (Peg-IFN)

This is a phase III trial comparing, for newly diagnosed chronic phase CML patients, nilotinib 600 mg BID as a standard arm and nilotinib 600 mg BID combined to interferon alfa 2 a (pegylated form improving tolerance and maybe enhancing is efficacy) at increased doses for a total of 24 months of combination, in a 1:1 randomized manner. The assessment for the primary efficacy endpoint will be performed at 12 months (since nilotinib initiation) and is the rate patients obtaining MR4.5 will be measured at this time point.

General Publications

  • Abstract We evaluated whether adding pegylated interferon-α2a (Peg-IFNα2a) to nilotinib affected dose intensity, molecular response kinetics, and long-term outcomes in newly diagnosed chronic myeloid leukemia. Delivered nilotinib doses remained comparable between treatment arms up to 72 months, indicating no dose reduction from Peg-IFNα2a-related toxicity. At diagnosis, 8.5 % of 199 patients had additional cytogenetic abnormalities (ACAs). At 3 months, complete and partial cytogenetic response (CCyR/PCyR) rates did not differ between nilotinib alone and the combination (CCyR 72.5 % vs 76 %; PCyR 16.5 % vs 11.5 %). Molecular kinetics showed faster early BCR::ABL1 transcript decline with the combination, but cumulative incidence (CI) curves for major molecular response (MMR) converged by 36 months. Two-year CI of MMR was 80.5 % with nilotinib and 91 % with the combination; five-year CI 93 % vs 97 % (global p = 0.155). The primary endpoint, MR4.5 at 12 months, was reached in 15 % vs 24 % (p = 0.048), but long-term deep molecular response rates (MR4/MR4.5) were ultimately similar at 5 years. In exploratory analyses, female sex (HR 3.06) and higher cumulative Peg-IFNα2a dose in the first 9 months (HR 2.89) predicted early MR4.5, whereas high Sokal or ELTS scores and elevated BCR::ABL1 at month 3 were adverse. ABL1 kinase domain mutations emerged in 10 patients overall (8 nilotinib, 2 combination). Conclusion Peg-IFNα2a with nilotinib accelerated early molecular responses and increased 12-month MR4.5 rates without impairing nilotinib exposure or long-term outcomes. Female sex and Peg-IFNα2a dose intensity correlated with deep early response, supporting potential personalization of combination strategies.
