Combination of pegylated IFN-alpha 2b with imatinib increases molecular response rates in patients with low- or intermediate-risk chronic myeloid leukemia
(2011) In Blood 118(12). p.3228-3235- Abstract
- Biologic and clinical observations suggest that combining imatinib with IFN-alpha may improve treatment outcome in chronic myeloid leukemia (CML). We randomized newly diagnosed chronic-phase CML patients with a low or intermediate Sokal risk score and in imatinib-induced complete hematologic remission either to receive a combination of pegylated IFN-alpha 2b (Peg-IFN-alpha 2b) 50 mu g weekly and imatinib 400 mg daily (n = 56) or to receive imatinib 400 mg daily monotherapy (n = 56). The primary endpoint was the major molecular response (MMR) rate at 12 months after randomization. In both arms, 4 patients (7%) discontinued imatinib treatment (1 because of blastic transformation in imatinib arm). In addition, in the combination arm, 34... (More)

The primary endpoint was the major molecular response (MMR) rate at 12 months after randomization. In both arms, 4 patients (7%) discontinued imatinib treatment (1 because of blastic transformation in imatinib arm). In addition, in the combination arm, 34 patients (61%) discontinued Peg-IFN-alpha 2b, most because of toxicity. The MMR rate at 12 months was significantly higher in the imatinib plus Peg-IFN-alpha 2b arm (82%) compared with the imatinib monotherapy arm (54%; intention-to-treat, P = .002). The MMR rate increased with the duration of Peg-IFN-alpha 2b treatment (< 12-week MMR rate 67%, > 12-week MMR rate 91%). Thus, the addition of even relatively short periods of Peg-IFN-alpha 2b to imatinib markedly increased the MMR rate at 12 months of therapy. Lower doses of Peg-IFN-alpha 2b may enhance tolerability while retaining efficacy and could be considered in future protocols with curative intent. (Blood. 2011;118(12):3228-3235) (Less)
