Thus, new, efective treatments are urgently needed, particularly for relapsed or refractory MM(RRMM). In an earlier phase I study, a novel form of recombinant human Apo2L/tumor necrosis factor-related apoptosis-inducing ligand(TRAIL) that is currently in clinical development for the treatment of hematologic malignancies, i.e., circularly permuted TRAIL(CPT), was well tolerated at a dose of 2.5 mg/kg per day and showed promising preliminary activity in patients with RRMM. This phase II, open-label, multicenter study further investigated the eicacy and safety of 2.5-mg/kg per day CPT as single-agent therapy for patients with RRMM.Methods: Patients with RRMM were treated once daily with CPT(2.5 mg/kg, intravenously) for 14 consecutive days for each 21-day cycle. Clinical response and toxicity were assessed after each treatment cycle.Results: Twenty-seven patients received CPT. Using the European Group for Blood and Marrow Transplantation criteria, we calculated the overall response rate of 33.3% with 1 near-complete response(n CR) and 8 partial responses(PRs). The clinical beneit rate(48.1%) included 1 nCR, 8 PRs, and 4 minimal responses. The most common treatmentrelated adverse events(TRAEs) were fever, aspartate aminotransferase elevation, alanine aminotransferase elevation, leucopenia, rash, neutropenia, and thrombocytopenia. We graded toxicity using the Common Toxicity Criteria for Adverse Events, version 3.0, and determined that 37.0% of patients had at least 1 grade 3–4 TRAE.Conclusions: CPT as a single agent can elicit a response in patients with RRMM and is well tolerated. Further clinical investigation is warranted.展开更多

The development of non-myeloablative conditioning regimens allows utilization of allogeneic effects in patients usually not suitable for myeloablative allogeneic transplantation, such as older and heavily pretreated patients. In a small series of 11 patients with multiple myeloma relapsing after autologous transplantation, we show that conditioning with low-dose total body irradiation in combination with fludarabine allows stable engraftment after matched unrelated donor transplantation and is tolerated with acceptable transplant-related morbidity and mortality. With a short median follow-up of 225 days, disease control was achieved only for patients responding to conventional treatment prior to allografting. Future studies with longer follow-up have to define the role of non-myeloablative allogeneic transplantation from unrelated donors as consolidation for patients responding to salvage therapy.展开更多

The drug is the first immunostimulatory drug to treat MM and used to treat recurrent/refractory multiple myeloma（R/RMM） in combination with lenalidomide and dexamethasone. Therefore, we collected the reports from existing clinical trials to analyze the efficacy of the drug in clinical applications to better evaluate the effects of the drug on R/RMM. The search strategy used ＂elotuzumab＂ and ＂multiple myeloma＂ as keywords to search from the database of Cochrane, Embase, Pub Med and Medline. The heterogeneity among the studies was assessed using the Cochrane χ~2 test, and its extent was evaluated using I^2 statistics. A P value of less than 0.05 was considered as statistically significant. All meta-analyses were conducted with R Software 3.3.2. We identified eight prospective studies consisting of 608 MM patients. The meta-analysis showed that the overall response rate（ORR） was 63%, 162 patients（26.6%） achieved a very good partial response rate（VGPR）, and 34 patients（5.59%） achieved complete response rate（CR）. The most common adverse effects of the drug included anemia, lymphopenia, thrombocytopenia, neutropenia and fatigue. Therefore, elotuzumab combination regimens offered clinical benefits to R/RMM patients, and such a combination therapy was a suitable option for continuous treatment for R/RMM patients.展开更多

This trial aimed to observe the efficacy and safety of different dose combinations of bortezomib and dexamethasone in the treatment of RRMM patients in China.Methods A total of 168 patients with relapsed multiple myeloma （MM） who were refractory to at lest two prior treatments were enrolled in this multicenter, open-label, non-randomized, prospective clinical trial. Twenty patients received 1.3 mg/m2 of bortezomib twice weekly for 2 weeks of a 3-week cycle for up to 8 cycles and oral or intravenous dexamethasone 20 mg on the day of and after each bortezomib dose （group 1）; 66 patients received less than 1.3 mg/m2（0.7-1.0 mg/m2） of bortezomib and dexamethasone 20 mg on the same schedule （group 2）; 37 patients received 1.3 mg/m2 of bortezomib and dexamethasone 40 mg （group 3） and 45 patients received less than 1.3 mg/m2 （0.7-1.0 mg/m2）of bortezomib and dexamethasone 40 mg （group 4）. The response was evaluated according to the criteria of the European Group for Blood and Marrow Transplantation and confirmed by an independent review committee. Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria, version 3.0. Results The median age of groups 1 to 4 was 61,62, 56, and 60 years, respectively. Most patients were in stages Ⅱ/Ⅲ of MM and the most common subtype was IgG The rate of overall response to bortezomib and dexamethasone of group 1 to 4 was 72.2% （13/18）, 73.8% （48/65）, 78.8% （26/33） and 78.0% （32/41） （P=0.91）, including a complete response rate of 22.2% （4/18）, 20.0% （13/65）, 33.3% （11/33） and 29.3% （12/41） （P=0.67）, respectively. There was no statistical significance in time to progression and overall survival among these 4 groups （P 〉0.05）. The most commonly adverse events of any grade in the entire 4 groups were fatigue, gastrointestinal effects, peripheral neuropathy and thrombocytopenia, and there was no significance in the number of adverse events among the 4 groups （P 〉0.05） except that peripheral neuropathy was reported more frequently in group 3 （36.3%） than in group 2 （13.8%, P 〈0.05） and group 4 （14.6%, P〈O.05）.Conclusions The combination of bortezomib and dexamethasone was associated with high responses in Chinese RRMM patients. No significant differences of efficacy were detected in different dose combinations of bortezomib and dexamethasone. Moreover, low dose of bortezomib reduced the incidence of peripheral neuropathy without affecting outcome in the treatment of patients with RRMM in China.展开更多

文摘Background: Despite the recent development of new therapies, multiple myeloma(MM) remains an incurable disease. Thus, new, efective treatments are urgently needed, particularly for relapsed or refractory MM(RRMM). In an earlier phase I study, a novel form of recombinant human Apo2L/tumor necrosis factor-related apoptosis-inducing ligand(TRAIL) that is currently in clinical development for the treatment of hematologic malignancies, i.e., circularly permuted TRAIL(CPT), was well tolerated at a dose of 2.5 mg/kg per day and showed promising preliminary activity in patients with RRMM. This phase II, open-label, multicenter study further investigated the eicacy and safety of 2.5-mg/kg per day CPT as single-agent therapy for patients with RRMM.Methods: Patients with RRMM were treated once daily with CPT(2.5 mg/kg, intravenously) for 14 consecutive days for each 21-day cycle. Clinical response and toxicity were assessed after each treatment cycle.Results: Twenty-seven patients received CPT. Using the European Group for Blood and Marrow Transplantation criteria, we calculated the overall response rate of 33.3% with 1 near-complete response(n CR) and 8 partial responses(PRs). The clinical beneit rate(48.1%) included 1 nCR, 8 PRs, and 4 minimal responses. The most common treatmentrelated adverse events(TRAEs) were fever, aspartate aminotransferase elevation, alanine aminotransferase elevation, leucopenia, rash, neutropenia, and thrombocytopenia. We graded toxicity using the Common Toxicity Criteria for Adverse Events, version 3.0, and determined that 37.0% of patients had at least 1 grade 3–4 TRAE.Conclusions: CPT as a single agent can elicit a response in patients with RRMM and is well tolerated. Further clinical investigation is warranted.

文摘Elotuzumab was approved by the US FDA in 2015 as a new drug for the treatment of multiple myeloma（MM）, and it became a new choice for MM patients. The drug is the first immunostimulatory drug to treat MM and used to treat recurrent/refractory multiple myeloma（R/RMM） in combination with lenalidomide and dexamethasone. Therefore, we collected the reports from existing clinical trials to analyze the efficacy of the drug in clinical applications to better evaluate the effects of the drug on R/RMM. The search strategy used ＂elotuzumab＂ and ＂multiple myeloma＂ as keywords to search from the database of Cochrane, Embase, Pub Med and Medline.

The meta-analysis showed that the overall response rate（ORR） was 63%, 162 patients（26.6%） achieved a very good partial response rate（VGPR）, and 34 patients（5.59%） achieved complete response rate（CR）. The most common adverse effects of the drug included anemia, lymphopenia, thrombocytopenia, neutropenia and fatigue. Therefore, elotuzumab combination regimens offered clinical benefits to R/RMM patients, and such a combination therapy was a suitable option for continuous treatment for R/RMM patients.
文摘Despite recent progress in multiple myeloma(MM)treatments,most patients will relapse and require additional treatment.Intravenous daratumumab,a human IgGκmonoclonal antibody targeting CD38,has shown good efficacy in the treatment of MM.A subcutaneous version of daratumumab was formulated to reduce the burden of intravenous infusions.We aimed to investigate the efficacy and safety of subcutaneous daratumumab in Chinese patients with relapsed/refractory MM based on the demonstrated noninferiority of subcutaneous daratumumab to intravenous daratumumab,with a shorter administration time and reduced infusion-related reaction rate in global studies.This phase 1,multicenter study(MMY1010;ClinicalTrials.gov Identifier:NCT04121260)evaluated subcutaneous daratumumab in Chinese patients with relapsed/refractory MM after 1 prior line(n=1)or≥2 prior lines(n=20)of therapy,including a proteasome inhibitor and an immunomodulatory drug.Primary endpoints were pharmacokinetics and safety.Mean(standard deviation)maximum trough concentration of daratumumab was 826(335)μg/mL,which was consistent with prior studies of subcutaneous daratumumab and intravenous daratumumab.Safety was consistent with safety profiles observed in other daratumumab studies,with no new safety concerns identified.Incidences of infusion-related reactions and injection-site reactions were low and consistent with other subcutaneous daratumumab studies.At a median follow-up of 7.5 months,the overall response rate was 57.1%,with a very good partial response or better rate of 38.1%and complete response or better rate of 19.0%.Our results demonstrate a favorable benefit/risk profile of subcutaneous daratumumab in Chinese patients with relapsed/refractory MM,potentially impacting clinical administration of daratumumab in this population.
文摘Background Although previous clinical study revealed that bortezomib combined with dexamethasone had improved the outcomes of relapsed or refractory multiple myeloma （RRMM）, the optimal dose combinations of bortezomib and dexamethasone remain unknown. This trial aimed to observe the efficacy and safety of different dose combinations of bortezomib and dexamethasone in the treatment of RRMM patients in China.Methods A total of 168 patients with relapsed multiple myeloma （MM） who were refractory to at lest two prior treatments were enrolled in this multicenter, open-label, non-randomized, prospective clinical trial. Twenty patients received 1.3 mg/m2 of bortezomib twice weekly for 2 weeks of a 3-week cycle for up to 8 cycles and oral or intravenous dexamethasone 20 mg on the day of and after each bortezomib dose （group 1）; 66 patients received less than 1.3 mg/m2（0.7-1.0 mg/m2） of bortezomib and dexamethasone 20 mg on the same schedule （group 2）; 37 patients received 1.3 mg/m2 of bortezomib and dexamethasone 40 mg （group 3） and 45 patients received less than 1.3 mg/m2 （0.7-1.0 mg/m2）of bortezomib and dexamethasone 40 mg （group 4）. The response was evaluated according to the criteria of the European Group for Blood and Marrow Transplantation and confirmed by an independent review committee. Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria, version 3.0. Results The median age of groups 1 to 4 was 61,62, 56, and 60 years, respectively. Most patients were in stages Ⅱ/Ⅲ of MM and the most common subtype was IgG The rate of overall response to bortezomib and dexamethasone of group 1 to 4 was 72.2% （13/18）, 73.8% （48/65）, 78.8% （26/33） and 78.0% （32/41） （P=0.91）, including a complete response rate of 22.2% （4/18）, 20.0% （13/65）, 33.3% （11/33） and 29.3% （12/41） （P=0.67）, respectively. There was no statistical significance in time to progression and overall survival among these 4 groups （P 〉0.05）. The most commonly adverse events of any grade in the entire 4 groups were fatigue, gastrointestinal effects, peripheral neuropathy and thrombocytopenia, and there was no significance in the number of adverse events among the 4 groups （P 〉0.05） except that peripheral neuropathy was reported more frequently in group 3 （36.3%） than in group 2 （13.8%, P 〈0.05） and group 4 （14.6%, P〈O.05）.Conclusions The combination of bortezomib and dexamethasone was associated with high responses in Chinese RRMM patients. No significant differences of efficacy were detected in different dose combinations of bortezomib and dexamethasone. Moreover, low dose of bortezomib reduced the incidence of peripheral neuropathy without affecting outcome in the treatment of patients with RRMM in China.
文摘目的探讨复发/难治性多发性骨髓瘤伴继发性髓外病变患者达雷妥尤单抗联合苯达莫司汀治疗的疗效和安全性。方法回顾性分析2021年1月至2023年12月于广西医科大学附属肿瘤医院住院治疗的复发/难治性多发性骨髓瘤伴继发性髓外病变患者的临床资料。所有患者均接受至少三线治疗仍疾病进展,然后采用达雷妥尤单抗和苯达莫司汀联合治疗。分别采用国际骨髓瘤工作组(International Myeloma Working Group,IMWG)标准和美国国家癌症研究所不良事件通用术语标准(NCI-CTCAE)5.0版评估其治疗疗效和安全性。结果共12例患者纳入分析,获完全缓解2例,部分缓解4例,微小缓解2例,疾病稳定1例,疾病进展3例,总缓解率为50%,中位无进展生存期为8个月。所有患者均出现血液学毒性,其中4例为Ⅲ~Ⅳ级;3例患者在治疗期间发生肺炎;均未发生治疗相关性死亡。结论达雷妥尤单抗联合苯达莫司汀在治疗复发/难治性伴继发性髓外病变的多发性骨髓瘤中显示出有效性,且毒性作用可控,值得在更大规模的患者群体中进一步验证。
文摘背景嵌合抗原受体(CAR)-T细胞免疫疗法已在多发性骨髓瘤(MM)中取得较好的疗效,最常见的靶点为B细胞成熟抗原(BCMA)。单靶点CAR-T细胞免疫疗法的缺点是会导致疾病抵抗和复发,可能与抗原逃逸有关。为此,改进开发了双靶点CAR-T细胞治疗复发难治多发性骨髓瘤(RRMM),此方面尚缺乏系统的临床分析。目的对RRMM患者应用双靶点CAR-T细胞免疫疗法治疗的有效性及安全性进行Meta分析。方法计算机检索PubMed、Embase、Cochrane Library、Web of Science、中国知网、万方数据知识服务平台、维普网7个数据库中有关双靶点CAR-T细胞治疗RRMM的单组率研究,检索时限为建库至2023-02-06。由2名研究人员使用自制的数据表单来提取收集数据,并采用非随机对照试验方法学评价指标进行文献质量评价。采用R Studio软件进行数据分析。结果共纳入9篇文献,包括200例既往接受过多线治疗的RRMM患者。双靶点CAR-T细胞疗法根据不同靶点可分为4类:BCMA+CD19、BCMA+CD38,BCMA+跨膜剂与钙调节亲环素配体的相互作用者(TACI)、BCMA+人信号淋巴细胞激活分子家族成员7(CS1),其中BCMA+CD19靶点的研究较多。根据输注形式不同CAR-T细胞疗法可分为4类:双特异性CAR-T细胞、联合或序贯输注两种不同CAR-T细胞、双顺反子结构、共转导。Meta分析显示,双靶点CAR-T细胞治疗RRMM的总缓解率(ORR)为90.0%(95%CI=0.849~0.943),完全缓解率(CRR)为54.6%(95%CI=0.416~0.673),微小残留病(MRD)阴性率为75.6%(95%CI=0.489~0.952),髓外病变(EMD)总缓解率为55.1%(95%CI=0.234~0.851),最后一次随访时的复发率为29.7%(95%CI=0.141~0.454),最后一次随访时的生存率为75.6%(95%CI=0.554~0.915),3~4级细胞释放因子综合征(CRS)发生率为16.4%(95%CI=0.094~0.245),神经毒性(ICANS)发生率为4.0%(95%CI=0~0.120)。敏感性分析提示结果稳定。Egger's检验结果显示,ORR(P=0.03)及EMD总缓解率(P=0.02)提示存在一定的偏倚风险;CRR(P=0.53)、MRD阴性率(P=0.79)、最后一次随访时的复发率(P=0.71)、生存率(P=0.98)、3~4级CRS发生率(P=0.90)、ICANS发生率(P=0.30)提示不存在发表偏倚。结论双靶点CAR-T细胞免疫治疗RRMM显示出良好的疗效和安全性,未来需要多中心、大样本、更长随访期的研究来进一步评估其疗效和安全性。
文摘目的观察国产苯达莫司汀+卡非佐米+地塞米松治疗复发/难治性多发性骨髓瘤(Relapse or Refractory Multiple Myeloma,RRMM)的临床疗效。方法回顾性选取2021年10月—2023年6月在广西玉林市红十字会医院血液肿瘤科就诊的32例RRMM患者的临床资料。所有患者均使用苯达莫司汀+卡非佐米+地塞米松方案再诱导治疗。评估患者的总有效率、无进展生成期、总生存期及不良反应。结果32例RRMM均接受国产苯达莫司汀+卡非佐米+地塞米松治疗1疗程以上,治疗中位疗程数为[4(1,8)]个,总有效率18例;≥非常好的部分缓解6例。32例患者随访中位PFS为[7.4(3.5,12.8)]个月,中位OS时间为[11.3(4.6,18.8)]个月。血液学不良反应较为常见的是中性粒细胞计数减少7例、血小板减少6例、贫血6例;非血液学不良反应中常见乏力18例、呼吸道感染6例、心脏事件5例,恶心4例及周围神经病变4例。结论苯达莫司汀+卡非佐米+地塞米松对治疗RRMM患者是一种较好的选择,临床治疗效果较好,不良反应性较轻。
