Treatment Free Remission (TFR) is an established goal for patients with the diagnosis of chronic myeloid leukemia (CML). The purpose of this prospective feasibility pilot study was assessing a new, real-world paradigm for safely stopping TKI treatment by monitoring molecular response through PCR tests determining BCR::ABL levels every 6 weeks instead of the recommended 4-week intervals. A successful re-establishment of MMR after loss of TFR was the primary endpoint. Eligibility criteria for this study included maintaining major molecular response 4 log reduction (MMR4) for 2 years and a total of TKI therapy for 5 years. The primary endpoint was successful maintenance of ≥ MMR at 6 months. 18 patients were enrolled, 13 of the 18 participants maintained TFR, and all 5 patients regained MMR with resumption of TKI treatment. We demonstrated that this pilot study was feasible in a community setting using 6-week intervals. This study will be expanded to other sites using a 6-week testing interval.
无治疗缓解(TFR)是诊断为慢性髓性白血病(CML)患者的既定目标。这项前瞻性可行性试点研究的目的是评估一种新的、现实世界的安全停止TKI治疗范例,通过PCR检测每6周检测BCR::ABL水平来监测分子反应,而不是推荐的每4周检测一次。TFR丢失后MMR的成功重建是主要终点。本研究的资格标准包括维持主要分子反应4 log reduction (MMR4) 2年,TKI治疗共5年。主要终点是6个月时MMR≥ 的成功维持。18例患者入组,其中13例患者维持TFR,所有5例患者在恢复TKI治疗后均恢复了MMR。我们以6周的间隔证明了该试点研究在社区环境中是可行的。这项研究将以6周的测试间隔扩展到其他地点。

Background

In chronic-phase chronic myeloid leukemia (CML-CP), switching tyrosine kinase inhibitor (TKI) therapy due to intolerance or resistance is common. While asciminib, an ABL/BCR::ABL1 TKI targeting the ABL myristoyl pocket, offers improved tolerability and efficacy, there is limited real-world effectiveness data, particularly among patients with treatment with one prior TKI.

Patients and methods

A retrospective, US physician panel-based chart review study was conducted on adult patients with CML-CP without T315I treated with asciminib after one prior TKI. Time-on-treatment, and time-to achieving or maintaining MR2 (BCR::ABL1 ≤ 1 %), MMR (BCR::ABL1 ≤ 0.1 %) and DMR (BCR::ABL1 ≤ 0.01 %) were assessed using Kaplan-Meier analyses. Subgroup analyses were performed among patients with first TKI discontinuation due to intolerance or resistance, and by first- or second-generation TKI as first TKI.

Results

Overall, 255 patients (median age 62 years, 56.5 % male) were included. Imatinib (49.8 %), dasatinib (34.5 %), nilotinib (10.6 %), and bosutinib (5.1 %) were received as first TKI. Intolerance and resistance to first TKIs were reported for 43.5 % and 23.5 % of patients, respectively. At 48-weeks post-asciminib initiation, 95.0 % of patients (95 % CI: 91.3 %, 97.1 %) remained on asciminib, 84.0 % (95 % CI: 78.6 %, 88.6 %) achieved or maintained MR2, 68.3 % (95 % CI: 61.8 %, 74.5 %) MMR, and 40.6 % (95 % CI: 34.2 %, 47.8 %) DMR.

Conclusions

Overall, most patients remained on treatment and achieved or maintained MMR, suggesting that asciminib was well-tolerated and effective. Results were consistent among subgroups, indicating that asciminib is an effective option for patients regardless of prior TKI used, and including those intolerant or resistant to their first TKI.

Micro-abstract

There is limited real-world data regarding the effectiveness of asciminib after one prior tyrosine kinase inhibitor (TKI) in chronic-phase chronic myeloid leukemia (CML-CP). In this US physician panel-based chart review, nearly all patients (95 %) remained on asciminib and 68 % achieved or maintained a major molecular response at 48 weeks, suggesting that asciminib is well-tolerated and effective after one prior TKI.
背景:在慢性粒细胞白血病(CML-CP)中,由于不耐受或耐药而切换酪氨酸激酶抑制剂(TKI)治疗是常见的。阿西米尼是一种针对ABL肉豆醇口袋的ABL/BCR::ABL1 TKI,可改善耐受性和疗效,但实际疗效数据有限,特别是在既往有过TKI治疗的患者中。患者和方法:一项回顾性的,美国医师小组为基础的图表回顾研究进行了成人CML-CP患者无T315I治疗阿西米尼之前的TKI。使用Kaplan-Meier分析评估治疗时间、达到或维持MR2 (BCR::ABL1 ≤1 %)、MMR (BCR::ABL1 ≤0.1 %)和DMR (BCR::ABL1 ≤0.01 %)的时间。在因不耐受或耐药而首次停用TKI的患者中进行亚组分析,并将第一代或第二代TKI作为首次TKI。结果:共纳入255例患者(中位年龄62岁,56.5 %为男性)。伊马替尼(49.8% %)、达沙替尼(34.5% %)、尼罗替尼(10.6% %)和博舒替尼(5.1% %)作为第一次TKI。首次TKIs耐受和耐药分别为43.5% %和23.5% %的患者。在48周post-asciminib启动,95.0 %的患者(95 % CI: 91.3 %,97.1 %)仍然在asciminib, 84.0 %(95 % CI: 78.6 %,88.6 %)实现或维护MR2, 68.3 %(95 % CI: 61.8 %,74.5 %)MMR,和40.6 %(95 % CI: 34.2 %,47.8 %)DMR。结论:总体而言,大多数患者继续接受治疗并达到或维持MMR,表明阿西米尼耐受性良好且有效。亚组之间的结果一致,表明阿西米尼对于患者是一种有效的选择,无论之前是否使用过TKI,包括那些对第一次TKI不耐受或耐药的患者。微摘要:关于阿西米尼在既往使用酪氨酸激酶抑制剂(TKI)治疗慢性粒细胞白血病(CML-CP)后的有效性的实际数据有限。在这项基于美国医师小组的图表回顾中,几乎所有患者(95% %)仍在使用阿西米尼,68 %的患者在48周时达到或维持了主要的分子反应,这表明阿西米尼在一次TKI后具有良好的耐受性和有效性。

As there are no prospective randomized studies in patients with advanced systemic mastocytosis (AdvSM), we compared clinical outcomes between patients treated with avapritinib in the Phase I EXPLORER (NCT02561988) and Phase II PATHFINDER (NCT03580655) trials (N = 176) and patients treated with midostaurin (N = 99) or cladribine (N = 49) from a global, multi-center, retrospective, chart review study. Overall survival (OS) and duration of treatment (DOT) were compared between the cohorts using inverse probability of treatment weighting (IPTW)-adjusted Cox proportional hazards models, and maximum reduction in serum tryptase levels was compared using adjusted generalized linear models. Median OS was not reached (95% confidence interval [CI]: 46.9 months, not estimable) for avapritinib, 28.6 (18.2, 44.6) months for midostaurin, and 23.4 (14.8, 40.6) months for cladribine. The avapritinib cohort had significantly longer OS compared to midostaurin (hazard ratio [HR] [95% CI]: 0.59 [0.36, 0.97]) and cladribine (0.32 [0.15, 0.67]), longer DOT (vs. midostaurin: 0.63 [0.41, 0.96]; vs. cladribine: 0.14 [0.09, 0.23]), and greater reduction in serum tryptase levels with mean difference [95% CI] vs. midostaurin of −72.8 % [−101.1 %, −44.6 %] and vs. cladribine of −25.0 % [−32.4 %, −17.7 %] (all p < 0.05). Results were similar in treatment-naïve (1 L) and previously treated (2 L+) patients; there was improved OS in 1 L avapritinib vs. 1 L midostaurin patients (HR: 0.14 [0.05, 0.42]; p < 0.001) and in 2 L+ avapritinib vs. 2 L+ cladribine patients (0.34 [0.16, 0.71]; p = 0.004). Together, we show that avapritinib treatment resulted in significantly improved OS, longer DOT, and greater reduction in serum tryptase levels compared to midostaurin or cladribine in real-world clinical practice.
由于没有针对晚期全身性肥大细胞增多症(AdvSM)患者的前瞻性随机研究,我们比较了一项全球、多中心、回顾性、图表回顾研究中,在I期EXPLORER (NCT02561988)和II期PATHFINDER (NCT03580655)试验(N = 176)中接受阿伐替尼治疗的患者与接受midoin (N = 99)或cladribine (N = 49)治疗的患者的临床结果。使用治疗加权逆概率(IPTW)校正的Cox比例风险模型比较两组患者的总生存期(OS)和治疗持续时间(DOT),并使用校正的广义线性模型比较血清胰蛋白酶水平的最大降幅。阿伐替尼的中位OS未达到(95%可信区间[CI]: 46.9个月,无法估计),米多舒林为28.6个月(18.2个月,44.6个月),克拉西滨为23.4个月(14.8个月,40.6个月)。avapritinib队列的OS明显高于midostoin(风险比[HR] [95% CI]: 0.59[0.36, 0.97])和cladribine (0.32 [0.15, 0.67]), DOT(相对于midostoin: 0.63 [0.41, 0.96];与cladribine相比:0.14[0.09,0.23]),血清胰蛋白酶水平降低幅度更大,平均差异[95% CI]与midosatin相比为- 72.8 %[- 101.1 %,- 44.6 %],与cladribine相比为- 25.0 %[- 32.4 %,- 17.7 %](p均为 <; 0.05)。treatment-naïve(1 L)和先前治疗(2 L+)患者的结果相似;1名 L avapritinib患者与1名 L midoin患者的OS改善(HR: 0.14 [0.05, 0.42];p <; 0.001),2例 L+ 阿伐替尼vs. 2例 L+ 克拉德滨(0.34 [0.16,0.71]; = 0.004页)。总之,我们表明,在现实世界的临床实践中,与米多舒林或克拉德里滨相比,阿伐替尼治疗显著改善了OS,延长了DOT,并显著降低了血清胰蛋白酶水平。

Myelodysplastic syndrome (MDS) is a hematological malignancy characterized by the clonal expansion of mutated hematopoietic stem and progenitor cells, resulting in morphological changes (dysplasia) in the bone marrow and cytopenia. Despite advancements in molecular diagnostics, MDS diagnosis often depends on subjective morphological evaluation of bone marrow smears. One objective criterion is cytogenetic analysis. Here, we present a deep learning-based approach to identify morphological abnormalities associated with cytogenetically defined MDS (cMDS) using whole slide images (WSIs) of bone marrow smears. To disentangle shape and textural features in WSIs, we developed a model analyzing segmented binary masks of red blood cells (RBCs) in addition to a conventional image classification model based on color images. Notably, the RBC morphology model achieved high diagnostic accuracy, even after controlling for anemia, uncovering a strong association between RBC shape and distribution—features previously overlooked by human experts—and cMDS. These findings propose RBC morphology as a novel biomarker for MDS and underscore the potential of artificial intelligence to enhance diagnostic precision and objectivity.
骨髓增生异常综合征(MDS)是一种血液学恶性肿瘤,其特征是突变的造血干细胞和祖细胞克隆扩增,导致骨髓形态改变(发育不良)和细胞减少。尽管分子诊断取得了进步,MDS的诊断往往依赖于骨髓涂片的主观形态学评价。一个客观的标准是细胞遗传学分析。在这里,我们提出了一种基于深度学习的方法,利用骨髓涂片的全幻灯片图像(WSIs)来识别与细胞遗传学定义的MDS (cMDS)相关的形态学异常。为了解开wsi的形状和纹理特征,除了基于彩色图像的传统图像分类模型之外,我们还开发了一个分析红细胞(rbc)分割的二元掩模的模型。值得注意的是,即使在控制贫血后,RBC形态学模型也获得了很高的诊断准确性,揭示了红细胞形状和分布(以前被人类专家忽视的特征)与cMDS之间的强烈关联。这些发现表明红细胞形态是MDS的一种新的生物标志物,并强调了人工智能在提高诊断准确性和客观性方面的潜力。

In a rare condition known as AIHA (Autoimmune Hemolytic Anemia), red blood cells are destroyed by the immune system. This type of anemia is it. More creative therapeutic options have emerged as a result of AIHA therapy outcomes, and these are thought to significantly improve the patient's condition. This summary sheds light on novel therapies that target specific pathways. B-cell-directed therapies, phagocytosis inhibitors, complement inhibitors, and FcRn inhibitors are examples of patient-specific, pathway-oriented treatments. These innovative treatments, which are yet to be implemented in clinical settings, have the potential to enhance the management of AIHA and can be used in conjunction with other treatments that have fewer side effects than conventional therapies. In addition to their potential, methods in this emerging field also make clinical adoption challenging. Striking a balance between delivering cutting-edge care and protecting physicians' income is difficult due to the high costs. Because they maximize treatment outcomes and enable treatments to be precisely tailored to each patient's unique needs, individualized medicine and combined therapies are extremely advantageous. To fully realize the potential of AIHA therapies and transform the way AIHA is managed, a number of obstacles must be removed and these treatments made easily accessible to all.
在一种被称为AIHA(自身免疫性溶血性贫血)的罕见疾病中,红细胞被免疫系统破坏。就是这种类型的贫血。由于AIHA治疗的结果,出现了更多创造性的治疗选择,这些被认为可以显着改善患者的病情。这一总结揭示了针对特定途径的新疗法。b细胞定向治疗、吞噬抑制剂、补体抑制剂和FcRn抑制剂是患者特异性、途径导向治疗的例子。这些尚未在临床环境中实施的创新疗法有可能加强对AIHA的管理,并可与其他副作用比传统疗法少的疗法联合使用。除了它们的潜力之外,这个新兴领域的方法也使临床应用具有挑战性。由于成本高昂,很难在提供尖端护理和保护医生收入之间取得平衡。由于它们能最大限度地提高治疗效果,并使治疗能够精确地针对每个患者的独特需求,因此个性化医疗和联合治疗非常有利。为了充分发挥AIHA疗法的潜力并改变AIHA的管理方式,必须消除一些障碍,使所有人都能轻松获得这些疗法。
