Efficacy of lenalidomide was investigated in 103 patients with relapsed/refractory chronic lymphocytic leukemia (CLL) treated on the prospective, multicenter randomized phase-II CLL-009 trial. Interphase cytogenetic and mutational analyses identified TP53 mutations, unmutated IGHV, or del(17p) in 36/96 (37.5%), 68/88 (77.3%) or 22/92 (23.9%) patients. The overall response rate (ORR) was 40.4% (42/104). ORRs were similar irrespective of TP53 mutation (36.1% (13/36) vs 43.3% (26/60) for patients with vs without mutation) or IGHV mutation status (45.0% (9/20) vs 39.1% (27/68)); however, patients with del(17p) had lower ORRs than those without del(17p) (21.7% (5/22) vs 47.1% (33/70); P=0.049). No significant differences in progression-free survival and overall survival (OS) were observed when comparing subgroups defined by the presence or absence of high-risk genetic characteristics. In multivariate analyses, only multiple prior therapies (⩾3 lines) significantly impacted outcomes (median OS: 21.2 months vs not reached; P=0.019). This analysis indicates that lenalidomide is active in patients with relapsed/refractory CLL with unfavorable genetic profiles, including TP53 inactivation or unmutated IGHV.

来那度胺的疗效在一项前瞻性、多中心随机II期CLL-009试验中进行了研究,该试验纳入了103例复发/难治性慢性淋巴细胞白血病(CLL)患者。间期细胞遗传学和突变分析发现,36/96例(37.5%)患者存在TP53突变,68/88例(77.3%)为未突变IGHV,22/92例(23.9%)存在del(17p)。总缓解率(ORR)为40.4%(42/104)。无论TP53突变状态(有突变 vs 无突变:36.1%(13/36) vs 43.3%(26/60))或IGHV突变状态(45.0%(9/20) vs 39.1%(27/68)),ORR均相似;然而,del(17p)患者的ORR低于无del(17p)的患者(21.7%(5/22) vs 47.1%(33/70);P=0.049)。按是否存在高危遗传特征定义的亚组进行比较时,无进展生存期和总生存期(OS)均未见显著差异。在多变量分析中,只有多次既往治疗(≥3线)显著影响结局(中位OS:21.2个月 vs 未达到;P=0.019)。该分析表明,来那度胺在具有不良遗传特征(包括TP53失活或未突变IGHV)的复发/难治性CLL患者中具有活性。(ClinicalTrials.gov标识符:NCT00963105)。
