Background: Imatinib mesylate (IM) discontinuation is under active investigation in chronic myeloid leukemia-chronic phase (CML-CP) patients with undetectable minimal residual disease (UMRD). However, limited data exist on the long-term outcomes following IM discontinuation in patients treated with frontline IM therapy. Methods: We consecutively enrolled patients with CML-CP who discontinued IM after achieving UMRD for ≥12 months between June 2009 and January 2013. Results: Nineteen patients (8 male, 11 female) were included. After IM discontinuation, 14 patients (74%) lost UMRD after a median of 4.0 months. Of the 14 patients with molecular relapses, 12 (86%) relapsed within the first 9 months after IM discontinuation and 2 (14%) relapsed at 20.5 and 22.8 months, respectively. No molecular relapse was observed after 2 years of IM discontinuation. With a median follow-up of 58.1 months (range 23.0-66.5), the estimated UMRD persistence rate at 5 years was 23.7%. IM was readministered in all patients with molecular relapse, and 12 patients (86%) reachieved UMRD at a median of 5.3 months. A high-risk Sokal score, delayed UMRD achievement and short-term IM therapy were significantly associated with molecular relapse. Conclusion: These findings suggest that IM discontinuation in patients who achieved UMRD after frontline IM therapy resulted in favorable long-term outcomes in terms of safety and feasibility.

AbstractIn the ENESTnd study, with ≥10 years follow-up in patients with newly diagnosed chronic myeloid leukemia (CML) in chronic phase, nilotinib demonstrated higher cumulative molecular response rates, lower rates of disease progression and CML-related death, and increased eligibility for treatment-free remission (TFR). Cumulative 10-year rates of MMR and MR4.5 were higher with nilotinib (300 mg twice daily [BID], 77.7% and 61.0%, respectively; 400 mg BID, 79.7% and 61.2%, respectively) than with imatinib (400 mg once daily [QD], 62.5% and 39.2%, respectively). Cumulative rates of TFR eligibility at 10 years were higher with nilotinib (300 mg BID, 48.6%; 400 mg BID, 47.3%) vs imatinib (29.7%). Estimated 10-year overall survival rates in nilotinib and imatinib arms were 87.6%, 90.3%, and 88.3%, respectively. Overall frequency of adverse events was similar with nilotinib and imatinib. By 10 years, higher cumulative rates of cardiovascular events were reported with nilotinib (300 mg BID, 16.5%; 400 mg BID, 23.5%) vs imatinib (3.6%), including in Framingham low-risk patients. Overall efficacy and safety results support the use of nilotinib 300 mg BID as frontline therapy for optimal long-term outcomes, especially in patients aiming for TFR. The benefit-risk profile in context of individual treatment goals should be carefully assessed.

Chronic myeloid leukemia (CML) is characterized by the presence of the BCR-ABL1 fusion gene. In more than 95% of CML patients, the typical BCR-ABL1 transcript subtypes are e13a2 (b2a2), e14a2 (b3a2), or the simultaneous expression of both. Other less frequent transcript subtypes, such as e1a2, e2a2, e6a2, e19a2, e1a3, e13a3, and e14a3, have been sporadically reported. The main purpose of this review is to assess the possible impact of different transcripts on the response rate to tyrosine kinase inhibitors (TKIs), the achievement of stable deep molecular responses (s-DMR), the potential maintenance of treatment-free remission (TFR), and long-term outcome of CML patients treated with TKIs. According to the majority of published studies, patients with e13a2 transcript treated with imatinib have lower and slower cytogenetic and molecular responses than those with e14a2 transcript and should be considered a high-risk group who would mostly benefit from frontline treatment with second-generation TKIs (2GTIKIs). Although few studies have been published, similar significant differences in response rates to 2GTKIs have been not reported. The e14a2 transcript seems to be a favorable prognostic factor for obtaining s-DMR, irrespective of the TKI received, and is also associated with a very high rate of TFR maintenance. Indeed, patients with e13a2 transcript achieve a lower rate of s-DMR and experience a higher probability of TFR failure. According to most reported data in the literature, the type of transcript does not seem to affect long-term outcomes of CML patients treated with TKIs. In TFR, the e14a2 transcript appears to be related to favorable responses. 2GTKIs as frontline therapy might be a convenient approach in patients with e13a2 transcript to achieve optimal long-term outcomes.
