Additional therapeutic options are needed for relapsed and refractory multiple myeloma (RRMM). We present data from a phase 1b, open-label, dose-escalation study (NCT01965353) of 20 patients with RRMM (median age: 63 years [range: 50–77]) and a median of four prior regimens (range: 2–14); 85% had refractory disease (lenalidomide [80%]; bortezomib [75%]; lenalidomide and bortezomib [50%]). Patients received a median of six cycles (range: 1–74) of panobinostat (10 or 15 mg), lenalidomide 15 mg, bortezomib 1 mg/m2, and dexamethasone 20 mg (pano-RVd). Median follow-up was ~14 months. Six dose-limiting toxicities were reported (mostly hematological); maximum tolerated dose of panobinostat (primary endpoint) was 10 mg. Most common adverse events (AEs) were diarrhea (60%) and peripheral neuropathy (60%); all grade 1/2. Grade 3/4 AEs occurred in 80% of patients and included decreased neutrophil (45%), platelet (25%) and white blood cell (25%) counts, anemia (25%) and hypophosphatemia (25%). No treatment-related discontinuations or mortality occurred. In evaluable patients (n = 18), overall response rate was 44%, and clinical benefit rate was 61%. Median duration of response was 9.2 months; progression-free survival was 7.4 months; overall survival was not reached. Pano-RVd proved generally well-tolerated and demonstrated potential to overcome lenalidomide and/or bortezomib resistance.
复发难治性多发性骨髓瘤(RRMM)需要更多的治疗选择。本研究报道了一项Ib期、开放标签、剂量递增试验(NCT01965353)的数据,该试验纳入了20例RRMM患者(中位年龄63岁[范围:50-77]),既往中位治疗线数为4线(范围:2-14);85%为难治性患者(对来那度胺[80%]、硼替佐米[75%]、来那度胺联合硼替佐米[50%]耐药)。患者接受了中位6个周期(范围:1-74)的帕比司他(10或15mg)、来那度胺15mg、硼替佐米1mg/m²及地塞米松20mg(pano-RVd方案)治疗。中位随访时间约为14个月。报告了6例剂量限制性毒性(主要为血液学毒性);帕比司他的最大耐受剂量(主要终点)为10mg。最常见的不良事件是腹泻(60%)和周围神经病变(60%),均为1/2级。80%的患者出现3/4级不良事件,包括中性粒细胞减少(45%)、血小板减少(25%)、白细胞减少(25%)、贫血(25%)和低磷血症(25%)。未发生治疗相关停药或死亡。在可评估患者(n=18)中,总体缓解率为44%,临床获益率为61%。中位缓解持续时间为9.2个月;无进展生存期为7.4个月;总生存期未达到。Pano-RVd方案总体耐受性良好,并显示出克服来那度胺和/或硼替佐米耐药的潜力。
