An open‐label phase I/II study of cyclophosphamide,bortezomib, pegylated liposomal doxorubicin,and dexamethasone in newly diagnosed myeloma

We conducted a phase 1/2 trial evaluating the combination of cyclophosphamide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone (CVDD) for newly diagnosed multiple myeloma (MM). The primary objective of the phase 1 was to evaluate the safety and tolerability of maximum planned dose (MPD) and the phase 2 was to assess the overall response rate. Patients received 6–8 cycles of CVDD at four dose levels. There were no dose‐limiting toxicities. The MPD was cyclophosphamide 750 mg/m² IV on day 1, bortezomib 1.3 mg/m² IV on days 1, 4, 8, 11, pegylated liposomal doxorubicin 30 mg/m² IV on day 4, and dexamethasone 20 mg orally on the day of and after bortezomib (21‐d cycle). Forty‐nine patients were treated at the MPD of which 22% had high‐risk myeloma. The most common grade ≥3 toxicities included myelosuppression, infection, and fatigue. Overall response and complete response rates were 91% and 26% in standard‐risk, and 100% and 58% in high‐risk cohort, respectively. After a median follow‐up of 34 months, the median progression‐free survival was 31.3 months. The 2‐yr overall survival was 91.1% in the standard‐risk and 88.9% in the high‐risk cohort, respectively. CVDD regimen was well tolerated and was highly active in newly diagnosed MM.     

Lenalidomide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone in newly diagnosed multiple myeloma: a phase 1/2 Multiple Myeloma Research Consortium trial

This phase 1/2 trial evaluated combination lenalidomide, bortezomib, pegylated liposomal doxorubicin, and dexamethasone (RVDD) in newly diagnosed multiple myeloma (MM) patients. Patients received RVDD at 4 dose levels, including the maximum tolerated dose (MTD). Patients with a very good partial response or better (≥ VGPR) after cycle 4 proceeded to autologous stem cell transplantation or continued treatment. The primary objectives were MTD evaluation and response to RVDD after 4 and 8 cycles. Seventy-two patients received a median of 4.5 cycles. The MTDs were lenalidomide 25 mg, bortezomib 1.3 mg/m(2), pegylated liposomal doxorubicin 30 mg/m(2), and dexamethasone 20/10 mg, as established with 3-week cycles. The most common adverse events were fatigue, constipation, sensory neuropathy, and infection; there was no treatment-related mortality. Response rates after 4 and 8 cycles were 96% and 95% partial response or better, 57% and 65% ≥ VGPR, and 29% and 35% complete or near-complete response, respectively. After a median follow-up of 15.5 months, median progression-free survival (PFS) and overall survival (OS) were not reached. The estimated 18-month PFS and OS were 80.8% and 98.6%, respectively. RVDD was generally well tolerated and highly active, warranting further study in newly diagnosed MM patients. This trial was registered at www.clinicaltrials.gov as NCT00724568.     

A modified regimen of pegylated liposomal doxorubicin,bortezomib, and dexamethasone is effective and well tolerated in the treatment of relapsed or refractory multiple myeloma

Preclinical and clinical studies have demonstrated synergy between bortezomib and pegylated liposomal doxorubicin (PLD) for relapsed/refractory (R/R) multiple myeloma (MM) patients compared to bortezomib as a single agent. This retrospective study evaluated the efficacy and safety of a more frequent low-dose schedule of PLD, bortezomib, and intravenous dexamethasone (DVD) for patients with R/R MM, many of whom were previously treated with bortezomib. Twenty-eight patients with R/R MM were treated, and 23 (83%) had been previously treated with ≥1 bortezomib-containing regimen. Treatment consisted of dexamethasone 40 mg intravenously, bortezomib 1.0 mg/m², and PLD 5.0 mg/m² on days 1, 4, 8, and 11 of a 28-day cycle for a maximum of eight cycles. Patients ranged from 33 to 81 years of age (median, 67) and had received 1–14 prior therapies (median, 5). At baseline, ten, nine, and nine patients were in stages I, II, and III, respectively, as defined by the International Staging System, and eight (29%) patients had elevated serum creatinine levels. The overall response rate was 61%, which included one (4%) complete response, three (11%) very good partial responses, eight (29%) partial responses, and five (18%) minimal responses. Of the 23 patients who had previously received bortezomib, 12 (52%) responded. The regimen was well tolerated with only six patients (21%) who showed worsening of their baseline peripheral neuropathy (PN). One patient discontinued this regimen due to an adverse event (grade II PN). DVD appears to represent a well-tolerated regimen with a high response rate for the treatment of R/R MM patients.     

硼替佐米为主的化疗方案治疗多发性骨髓瘤50例临床分析

目的：研究硼替佐米（万珂）为主的化疗方案治疗多发性骨髓瘤（MM）的疗效和安全性。方法：收集近4年来我科住院和随访的MM患者91例的临床资料,其中50例接受万珂为主化疗方案（VDT组）;41例接受传统化疗方案（VADT）。分析并比较2组患者的年龄、性别、β2-微球蛋白值、白蛋白值和2组的缓解率及不良反应。疗效评价按照欧洲骨髓移植协作组（EBMT）标准。结果：2组患者的年龄、性别、疾病分期无明显差异。中位随访20个月,发现VDT组50例患者总体反应率为88%,平均2个疗程即起效。其中初治患者CR＋nCR率明显优于同组复发难治患者以及传统方案治疗组,且初治患者的总缓解率在VDT组与VADT组中存在显著差异。VDT组不良反应以周围神经病变和血小板减少为常见,经对症治疗均可缓解。结论：万珂为主的化疗方案治疗初治和复发难治MM患者,起效快,其中初治患者CR＋nCR率及总缓解率更高,其不良反应可耐受。对有不良核型和IgD型MM患者,如何提高疗效尚待研究。     

Extended follow-up of outcome measures in multiple myeloma patients treated on a phase I study with bortezomib and pegylated liposomal doxorubicin

A phase I study of a combination of the proteasome inhibitor bortezomib and pegylated liposomal doxorubicin showed significant anti-tumor activity against advanced multiple myeloma, with 36% of patients achieving a complete or near-complete response and 73% having a partial response or better. Given this encouraging efficacy, it was therefore of interest to update the prior experience and define parameters such as time to progression, time to retreatment, and overall survival. Additional follow-up was collected on all evaluable multiple myeloma patients and revealed a median time to progression of 9.3 months versus 3.8 months on whatever had been the patient’s prior therapy. Time to retreatment was prolonged from 5.9 months after the patient’s prior therapy to 24.2 months after bortezomib with pegylated liposomal doxorubicin. The median overall survival after therapy with bortezomib and pegylated liposomal doxorubicin was 38.3 months. These findings compare favorably with results reported for bortezomib alone and support the possibility that the bortezomib/pegylated liposomal doxorubicin regimen may provide superior efficacy against relapsed/refractory multiple myeloma.     

三氧化二砷联合VTD方案治疗多发性骨髓瘤的疗效观察

目的本研究观察三氧化二砷联合VTD方案化疗治疗初治多发性骨髓瘤（MM）的临床疗效。方法11例初治的多发性骨髓瘤（MM）患者,中位年龄62．6岁,最大年龄83岁,接受预先短程三氧化二砷（As203）再联合硼替佐米、沙利度胺、地塞米松（VTD方案）治疗,每例患者至少接受2—6个疗程的治疗。观察其总体有效率及毒副作用的发生情况。结果11例初治的患者中3例完全缓解（CR）,6例非常好的部分缓解（VGPR）,2例部分缓解（PR）。治疗后,总有效率达100％。最长随访治疗17个月,均保持持续缓解状态。主要不良反应包括周围神经症状、水肿、乏力和血小板减少,经对症治疗后均能改善,未发现严重毒副作用。结论三氧化二砷联合VTD方案化疗治疗初治的、尤其老年MM安全、有效,有良好治疗前景。     

A modified regimen of pegylated liposomal doxorubicin, bortezomib and dexamethasone (DVD) is effective and well tolerated for previously untreated multiple myeloma patients

The combination of pegylated liposomal doxorubicin (PLD), bortezomib and dexamethasone has shown efficacy in the treatment of multiple myeloma (MM) patients. Our earlier retrospective study suggested that modification of the doses, schedules and route of administration of these drugs appears to reduce toxicity without compromising anti‐MM activity. As a result, we evaluated this modified drug combination in the frontline setting in a prospective multicentre phase II trial. Thirty‐five previously untreated MM patients were enrolled. Dexamethasone IV 40 mg, bortezomib 1 mg/m² and PLD 5 mg/m² were administered on days 1, 4, 8 and 11 of a 4‐week cycle. Patients were treated to their maximum response plus two additional cycles. The treatment regimen was discontinued after a maximum of eight cycles. Our modified schedule and dosing regimen achieved a high overall response rate of 86%, while showing a marked decrease in the incidence and severity of peripheral neuropathy, palmar‐plantar erythrodysesthesia and myelosuppression compared to the standard dosing on a 3‐week cycle using these drugs. This modified regimen of dexamethasone, bortezomib and PLD shows improved tolerability and safety while maintaining a high response rate when compared to standard treatment with these agents in the frontline setting.

Abstract：

Objective The aim of this phase Ⅱ study was to determine the efficacy and safety of combined bortezomib and thalidomide (VT) regime as initial treatment for newly diagnosed multiple myeloma (MM) in China. Methods Thirty-four patients were enrolled in this study and received VT regime up to 21-day cycles. Bortezomib (1.3 mg/m2) was administered intravenously on days 1, 4, 8, and 11, while oral thalidomide ( 100 mg/day) was given from days 1 to 21. The primary end point was clinical response.The secondary end point was safety. Results Among the 34 patients, 20 were male, 14 were female, with a median age of 59 years, and 15 in international stage system (ISS) Ⅲ ,18 in ISS Ⅱ , 1 in ISS Ⅰ . Among them, 28 completed 2 cycles' treatment and achieved an overall response rate (ORR) of 92.9%; 26 were able to complete the planned 8 cycles of therapy. After 8 cycles, the ORR was 100% ( complete response 30. 8%, near-complete response 23.1%, partial response 42. 3%, minimal response 3.8% ). After followed up with a median time of 12 months, the estimated rate without progress of disease was 62%, and the estimated continous remission rate of 12 months was 62%. The median survival time was not achieved. The most common adverse events were mild to moderate ( grades 1, 2). The main toxicities were hematologic (53. 3% ), gastrointestinal ( 40. 0% ), peripheral neuropathy ( 38.0% ), fatigue ( 36. 6% ) and fever (32. 0% ). Conclusions VT regime provides a very high ORR and complete response rate in the treatment of newly diagnosed MM patients. No patients experienced deep venous thrombosis. In conclusion,bortezomib in combination with thalidomide is a very effective regimen for newly diagnosed MM patients and the toxicities are manageable.
