- MR 4log and low levels of NK cells are associated with higher molecular relapse after imatinib discontinuation: Results of a prospective trial(2021) SEGURO, Fernanda S.; MACIEL, Felipe V. R.; SANTOS, Fernanda M.; ABDO, Andre N. R.; PEREIRA, Thales D. M.; NARDINELLI, Luciana; ROCHA, Vanderson; BENDIT, IsraelBackground: Treatment-free survival (TFS) in chronic myeloid leukemia (CML) is a new goal. This prospective study aims to evaluate imatinib discontinuation's feasibility and safety in patients with deep molecular response MR4 (BCR-ABL1 < 0.01 % IS). Methods: Study was approved by the ethical committee and registered at Clinicaltrials.gov (NCT03239886). Incluision criteria were: age >= 18y, chronic phase, first-line imatinib for 36 months, MR4 for 12 months, no previous transplant or resistance. Imatinib was resumed when two samples confirmed the loss of MMR. The primary endpoint was molecular recurrence-free survival (MRFS) at 24 months. Lymphocyte subpopulations were counted in peripheral blood before discontinuation. Results: 31 patients were included from Dec/2016 until Oct/2017. Median age was 54years, 58 % male, 58 % low Sokal, 65 % b3a2 transcripts, and 61 % were in MR4.5. Imatinib therapy's median time was 9.7y (3-14.9 y), median time of MR4 was 6.9y (1.6-10.3y). MRFS at 24 months was 55 % (95 % CI 39-75). Thirteen patients relapsed, 46 % after six months of discontinuation, and all patients recovered MMR. Median time to recover MMR was one month. MR4.5 was the only factor associated with MRFS. NK cells proportion at baseline was lower in patients with only MR4 who relapsed after discontinuation. Conclusion: With a median duration of sustained MR4 above five years, as recommended by most TKI discontinuation guidelines, the TFS was similar to previous studies. Only MR4.5 was associated with lower risk of relapse. Further studies are needed to evaluate whether patients with only MR4 and low NK cell levels are suitable for discontinuation.

In ASCEMBL, patients with CML-CP treated with >= 2 prior TKIs were randomized (stratified by baseline major cytogenetic response [MCyR]) 2:1 to asciminib 40 mg twice daily or bosutinib 500 mg once daily. Consistent with previously published primary analysis results, after a median follow-up of 2.3 years, asciminib continued to demonstrate superior efficacy and better safety and tolerability than bosutinib. The major molecular response (MMR) rate at week 96 (key secondary endpoint) was 37.6% with asciminib vs 15.8% with bosutinib; the MMR rate difference between the arms, after adjusting for baseline MCyR, was 21.7% (95% CI, 10.53-32.95; two-sided p = 0.001). Fewer grade >= 3 adverse events (AEs) (56.4% vs 68.4%) and AEs leading to treatment discontinuation (7.7% vs 26.3%) occurred with asciminib than with bosutinib. A higher proportion of patients on asciminib than bosutinib remained on treatment and continued to derive benefit over time, supporting asciminib as a standard of care for patients with CML-CP previously treated with >= 2 TKIs.

Asciminib, a first-in-class BCR-ABL1 inhibitor Specifically Targeting the ABL Myristoyl Pocket (STAMP), has the potential to overcome resistance/intolerance to approved TKIs. In this phase 3, open-label study, patients with CML-CP previously treated with >= 2 TKIs were randomized (2:1) to receive asciminib 40 mg twice daily vs bosutinib 500 mg once daily. Randomization was stratified by major cytogenetic response (MCyR) status at baseline. The primary objective was to compare the major molecular response (MMR) rate at week 24 for asciminib vs bosutinib. A total of 233 patients were randomized to asciminib (n = 157) or bosutinib (n = 76). Median follow-up was 14.9 months. The MMR rate at week 24 was 25.5% with asciminib and 13.2% with bosutinib. The difference in MMR rate between treatment arms, after adjusting for MCyR at baseline, was 12.2% (95% confidence interval, 2.19-22.30; 2-sided P = .029). Fewer grade >= 3 adverse events (50.6% vs 60.5%) and adverse events leading to treatment discontinuation (5.8% vs 21.1%) occurred with asciminib than with bosutinib. The study showed a superior efficacy of asciminib compared with that of bosutinib, together with a favorable safety profile. These results support the use of asciminib as a new therapy in patients with CML-CP who are resistant/intolerant to >= 2 prior TKIs.
