Richter’S Syndrome

Abstract Background: To evaluate the efficacy and safety of venetoclax, rituximab plus dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (VR-DA-EPOCH) in Richter's syndrome (RS), we conducted a single-arm, retrospective, observational, real-world study in our center. Methods: Patients who had history of CLL/SLL were diagnosed as RS by biopsy during treatment or watch and wait strategy. VR-DA-EPOCH was given as follow, venetoclax was administered with accelerated ramp-up from 20 mg per day to 400 mg per day, d1-10 during cycle 1, 400 mg daily on day1-10 of cycle 2-6, rituximab 375 mg/m 2 on day 0 of cycle 1 and 500 mg/m 2 on day 0 of cycle 2-6, plus etoposide (50 mg/m 2,day1-4), vincristine (0.4 mg/m 2 day 1-4) or vindesine 3 mg/m 2 day 1 , doxorubicin (10 mg/m 2 day 1-4), prednisone (60 mg/m 2, day 1-5), cyclophosphamide (750 mg/m 2 day 5), 21 days per cycle，dose adjustment on the basis of nadir ANC and platelet count are as previously reported by Wison WH. Response assessment was conducted after 2 or 3 cycles by enhanced CT or PET/CT and after 6 cycles (EOT) by PET/CT according to 2014 Lugano criteria. Minimal residual disease (MRD) of CLL cell in peripheral blood (PB) and bone marrow (BM) was detected after 2 or 3 and 6 cycles by flow cytometry. uMRD was defined as less than 1 CLL cell per 10 4 leukocytes. Results: 7 RS patients were enrolled in Pukou CLL Center from 10/2019 to 7/2021 and the last follow up was 07/25/2021. The median age was 52 years old. Unmutated IGHV, complex karyotype (CK) and TP53 deletion and/or mutation was detected in 100% (6/6), 20% (1/5) and 40% (2/5) patients, respectively. 5 patients received at least one prior line (range: 1-5) treatment for CLL/SLL, with 4 patients received ibrutinib as last prior therapy and one patient previously exposed to venetoclax. 2 patients were diagnosed as RS during watch and wait. The median duration from diagnoses or previous treatment for CLL/SLL to RS was 12 months (range: 3-14). All patients underwent lymph node (n=6) or bone biopsy(n=1) at the site of SUVmax or secondary SUV uptake (unaccessible for SUVmax) by PET/CT and was confirmed as transformed to non-GCB type of diffuse large B-cell lymphoma (DLBCL). Furthermore, 4 of 4 (100%) available patients were confirmed as clonal-related RS by detecting IGHV gene usage. 3 patients acquired CK, and 2 patients appeared BTK C481S mutation. 7 patients completed at least 2 cycles and were available for efficacy and safety assessment. Overall response rate (ORR) was 100% after 2 or 3 cycles, and CR rate (CRR) was 60% after 6 cycles in 5 patients who completed 6 cycles. 2 patients experience disease progression (PD) after cycle 2 and cycle 4 respectively, with one ceased after the addition of brentuximab and the other received CD20 UCAR-T and progressed 3 months later, transit to allo-hemapoietic stem cell transplant (allo-HCT). One patient received auto-hemapoietic stem cell transplant (auto-HCT) and CD19-CAR-T as consolidation and remains in CR, one patient experience PD after 6 cycles and attained CR with chidamide , programmed death-1 (PD-1) inhibitor Sintilimab and XPO1 inhibitor Selinexor, bridging to allo-HCT and remains in CR. Another patient who achieved CR after 6 cycles progressed 6 months later and ceased within one month. 2 patients transformed without previous treatment wait for final evaluation. 60% (3/5) patients attained MRD negativity both in the PB and BM after 6 cycles. The median tolerable dose was 60% (50%-70%) of standard EPOCH and the median dose of venetoclax was 400mg daily for 7 days each cycle. No tumor lysis syndrome (TLS) happened during venetoclax ramp-up. The most common grade 3 or 4 adverse effects (AEs) was agranulocytic fever (6/7, 85.7%), thrombocytopenia (3/7, 42.9%) and sepsis (2/7, 28.6%). 3 (42.9%) patients discontinued venetoclax due to severe AEs and the median duration of discontinuation was 3 days. 85.7% (6/7) had venetoclax dose reduction or interruption due to grade 3 or 4 neutropenia. Conclusion: VR-DA-EPOCH showed high response rate, impressive CR with uMRD and manageable toxicity in patients with RS, even with previous exposure to new target drugs. VR-DA-EPOCH could be recommended as an effective treatment choice for RS, CAR-T or allo-HCT should be considered as subsequent strategy for long term disease control. Figure 1 Figure 1.

Abstract Abstract 445 Background: Carfilzomib is a proteasome inhibitor that irreversibly binds its target and has a favorable toxicity profile that has shown significant activity in relapsed multiple myeloma (MM), leading to recent FDA accelerated approval. To achieve rapid and deep response in patients eligible for stem cell transplant, we combined carfilzomib with the regimen of cyclophosphamide-thalidomide-dexamethasone (CTD). We recently reported the results of the Phase I component of the trial (in which no MTD was reached) followed by the initial Phase II trial; however, with increasing evidence for the safe and effective use of higher doses of carfilzomib, we now report results from dose escalation extension of the Phase II trial. Methods: Newly diagnosed myeloma patients intended for stem cell transplant were eligible. All patients were treated on a 28 day cycle with Carfilzomib IV Days 1,2,8,9,15,16 (see Table 1 below for dosing per cohort) along with Cyclophosphamide 300 mg/m2 PO Days 1,8,15, Thalidomide 100 mg PO Days 1–28 and Dexamethasone 40 mg PO Days 1,8,15,22. We initially conducted a Phase I run in trial of 6 patients with no DLT observed before expanding to the Phase II portion of the study. The initial phase II regimen is shown below – as no DLTs were observed, we have now fully accrued to the Phase II dose level +1. Treatment was for 4 cycles with expected SCT post induction. The primary endpoint of the trial is the proportion of patients who have ≥very good partial response (VGPR) to treatment. All patients received herpes zoster prophylaxis and ASA daily. Results: A total of 38 patients have been accrued to the trial, 6 in the initial Phase 1, 21 in the initial Phase II, and the remaining at dose escalated cohorts. We are reporting the 27 patients who have completed therapy and will update with the dose escalated cohorts. Median age was 65 (range 27–74) and 52% were female. ISS Stage was advanced (II-III) in 56%. Best overall response rate during 4 cycles of CYCLONE at dose level 0 is 96%: CR 29%, VGPR 46%, PR 21% (1 pt achieved MR). Adverse events of grade 3 or higher at least possibly related to CYCLONE occurred in 12 (44%). Most commonly reported non hematological toxicities (all grades) included fatigue (67%), constipation (56%), lethargy (41%) somnolence (37%), malaise (30%) depressed level of consciousness (22%); however, grade 3/4 toxicities occurring in >5% were uncommon: thromboembolic event 11%) and muscle weakness (7%). Two cases of pneumonia required hospitalization. Eight patients (30%) developed grade 1 sensory neuropathy; no higher grade or painful neuropathy was evident. There were no cardiac events seen in greater than 5% of patients. Grade 3/4 hematological toxicities included neutropenia (15%) and lymphopenia (7%). All patients advancing to SCT successfully collected stem cells. One patient died on study from pneumonia. Conclusion: The 4 drug CYCLONE regimen is highly efficaceous with a response rate after only 4 cycles of 96% (75% ≥VGPR, 29% CR) at the current dosing level of carfilzomib IV 20/27 mg/m2 in newly diagnosed myeloma. Toxicities are manageable, with only grade 1 neuropathy and minimal cardiac or pulmonary toxicity. Increasing the dose of carfilzomib is feasible and updated results of dose escalated cohorts will be reported at 20/36 and 20/45 mg/m2.

Abstract Background: High dose chemotherapy with stem cell transplant is currently employed in relapsed/refractory aggressive Non-Hodgkin’s Lymphoma (NHL). Lenalidomide (Revlimid®), an immunomodulatory drug, has shown activity in hematological malignancies including relapsed/refractory multiple myeloma, chronic lymphocytic leukemia and cutaneous T-cell lymphoma. Aim: To determine the activity and safety of lenalidomide monotherapy in relapsed/refractory aggressive NHL following stem cell transplant (SCT). Methods: Patients with relapsed/refractory aggressive NHL with measurable disease ≥ 2 cm after at least 1 prior treatment regimen were eligible. Patients received 25 mg lenalidomide orally once daily on Days 1–21 every 28 days and continued therapy for 52 weeks as tolerated or until disease progression. Response and progression were evaluated using the IWLRC methodology. Results: Fourteen (29%) of the 49 patients enrolled into the study had a prior SCT. Median age was 61 (23–76) and 5 were female. Histology was diffuse large B-cell lymphoma [DLBCL] (n=5), follicular center lymphoma grade 3 [FL] (n=2), mantle cell lymphoma [MCL] (n=5) and transformed [TSF] (n=2). Median time from diagnosis to lenalidomide was 3.9 (1.1–31.4) years and median time from SCT to study entry was 1.9 (0.5–11.7) years. The median number of prior treatment regimens was 5 (2–8). Seven patients (50%) exhibited an objective response (1 complete response unconfirmed (CRu), and 6 partial responses (PR)), 5 had stable disease (SD) and 2 patients had progressive disease (PD). Six responses were in eight patients having a tumor burden < 50 cm2 and a time since last rituximab therapy of ≥ 230 days. One response was achieved in six patients having a tumor burden ≥ 50 cm2 or a time since last rituximab therapy of < 230 days. Four of 6 (67%) patients who had SCT as their last treatment prior to lenalidomide [median time from SCT to lenalidomide = 0.8 (0.5–4.8) years] responded. Progression free survival [PFS] is 4.5 months and ongoing. Six patients (43%) required at least one dose reduction with a median time to first dose reduction of 1.6 months (0.4–4.9). Two patients each (14%) had Grade 4 adverse events of neutropenia and thrombocytopenia. The most common Grade 3 adverse events were neutropenia (36%), thrombocytopenia (21%), and leukopenia (14%). Conclusion: Lenalidomide produced a 50% response rate with manageable side effects in relapsed/refractory aggressive NHL following stem cell transplant.

The use of 225Ac in prostate-specific membrane antigen (PSMA)-targeted radioligand therapy (RLT), either as monotherapy or in combination with 177Lu, is a promising therapy approach in patients with metastatic castration-resistant prostate carcinoma (mCRPC). In this study, we report the efficacy and safety of [225Ac]Ac-PSMA-617 augmented [177Lu]Lu-PSMA-617 RLT in 177Lu-naive mCRPC patients (n = 15) with poor prognosis (presence of visceral metastases, high total tumor burden with diffuse bone metastases or a short PSA doubling time of <2 months). Biochemical (by PSA serum value) and molecular imaging response (by [68Ga]Ga-PSMA-11 PET/CT) was assessed after two cycles of [177Lu]Lu-PSMA-617 RLT, with at least one [225Ac]Ac-PSMA-617 augmentation. In addition, PSA-based progression-free survival (PSA-PFS), overall survival (OS) and toxicity (according to CTCAE) were analyzed. We observed a biochemical- and molecular imaging-based partial remission in 53.3% (8/15) and 66.7% (10/15) of patients, respectively. The median PSA-PFS and OS was 9.1 and 14.8 months, respectively. No serious acute adverse events were recorded. Two out of fifteen patients experienced grade 3 anemia. No other grade 3/4 toxicities were observed. RLT-related xerostomia (grade 1/2) was recorded in 2/15 patients. Our data showed a high clinical efficacy with a favorable side effects profile of [225Ac]Ac-PSMA-617 augmented [177Lu]Lu-PSMA-617 RLT in this highly challenging patient cohort.

TPS7571 Background: The majority of patients (pts) with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who relapse after HSCT, or who are not candidates for HSCT have poor outcomes and are in need of novel therapies. Brentuximab vedotin (BV) is a CD30-directed ADC and preclinical data provide a strong rationale for combining BV, lenalidomide, and rituximab in the treatment of R/R DLBCL. In addition, in a phase 1 trial in which 37 pts with R/R DLBCL were treated with BV + lenalidomide, the ORR was 56.7% (73.3% in CD30+ pts; manuscript in preparation). The median duration of remission was 13.2 months in pts with a CR or PR and 11.7 months in pts with CR, PR, or stable disease > 6 months. The PFS and median OS were 11.2 months and 14.3 months, respectively and results were similar in the CD30+ and CD30 < 1% groups. The clinical activity and manageable safety profiles of BV, lenalidomide, and rituximab as single agents, make the combination a viable option in multiply relapsed and heavily pretreated pts. Methods: This is a randomized, double-blind, placebo-controlled, active-comparator, multicenter phase 3 study designed to evaluate the efficacy of BV vs placebo, in combination with lenalidomide + rituximab, in subjects with R/R DLBCL (NCT04404283). Prior to randomization, there will be a safety and PK run-in period where 6 pts will receive BV, lenalidomide + rituximab, and safety and PK will be evaluated after the first cycle of treatment; 6/6 subjects have been enrolled. Key eligibility criteria include: pts aged ≥18 with R/R DLBCL with an eligible subtype; ≥2 prior lines of therapy and must be ineligible for, or have declined, stem cell transplant, and chimeric antigen receptor T-cell (CAR-T) therapy; ECOG 0 to 2; fluorodeoxyglucose-avid disease by PET and bidimensional measurable disease of at least 1.5 cm by CT. Patients (n = 400) will be randomized 1:1 to receive either BV or placebo in combination with lenalidomide + rituximab and will be stratified by CD30 expression (positive [ ≥1%] versus < 1%), prior allogeneic or autologous stem cell transplant therapy (received or not), prior CAR-T therapy (received or not), and cell of origin (GCB or non-GCB). The primary endpoints are PFS per BICR in the ITT and CD30+ populations. Key secondary endpoints are OS in the ITT and CD30+ populations, and ORR per BICR. Other secondary endpoints include CR rate, duration of response, and safety and tolerability of the combination. Disease response will be assessed by BICR and the investigator according to the Lugano Classification Revised Staging System. Radiographic disease evaluations, including contrast-enhanced CT scans and PET, will be assessed at baseline, then every 6 weeks from randomization until Week 48, then every 12 weeks. PET is not required after CR is achieved. The trial is currently enrolling and will be open in 16 countries. Clinical trial information: NCT04404283.

Background: Eighty-five percent of PMBCL are cured by standard therapy, but the outcome of refractory/relapsed (R/R) PMBCL is very poor. Checkpoint inhibitors (CPIs) have shown promising activity in relapsed PMBCL. Axibactagene ciloleucel (axi-cel) CAR-T cell therapy, can induce durable responses and is currently approved for the treatment of adult patients with R/R PMBCL. Aims of this analysis were: to register all Italian PMBCL patients candidate to CAR-T in the 6 active centers;to evaluate the intention to treat overall response rate (ORR, complete [CR] and partial response [PR]) in patients treated with axi-cel and CPIs for salvage or bridging before CAR-T and for relapse after CAR-T;to evaluate cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Methods: In August 2019 the Italian Drug Agency (AIFA) approved axi-cel; before the reimbursement by AIFA, an expanded access program supported by Kite/Gilead started. One patient slot per month per qualified center was available. Patients were included in a large national CAR-T prospective observational study approved by ethics committees. Results: Since April 2019 to March 2020, 20 R/R PMBCL were evaluated and 18 were apheresized in order to receive axi-cel; 2 were excluded because active CNS disease in one, and eligibility to transplant, while in CR, in the second one. Their clinical characteristics were: median age 38 years (range 22-50), male 8 (44%), stage II 6 (33%), advanced stage III/IV 12 (66%), bulky disease 6 (33%); LDH upper than normal 3 (2%). Median number of prior lines was 3 (2-6); 5 patients (28%) had a previous autologous stem cell transplant and 12 (66%) received a prior radiotherapy. The majority of patients, 16 (89%) were refractory to the last treatment when they were evaluated for CAR-T eligibility; 9 of 18 patients had CPI exposure before leukoapheresis: 6 pembrolizumab and 3 nivolumab in combination with brentuximab-vedotin. No manufacturing failures were reported. Bridging therapy was performed in 16 of 18 patients (88%). Seventeen patients (94%) received lymphodepleting Flu-Cy chemotherapy and only 16 pts received CAR-T for central nervous system (CNS) progression during bridging therapy (n=1) and respiratory failure due to pneumonia (n=1); the 2 patient not infused were exposed to CPIs. Median vein to vein time was 40 days (30-79). Median follow-up time for infused patients was 209 days (9-444). CRS was observed in 12 of 16 infused patients: 5 grade 2 and 7 grade 1. ICANS (2 grade 1, 2 grade 2, 1 grade 3) was recorded in 5 patients. No differences regarding CRS and ICANS occurrence were observed in patients exposed or not to CPIs. At 30-days after the infusion, all the 16 infused patients were evaluable for response: 7 (44%) CR, 5 (31%) PR, with ORR 75%, 3 (19%) stable disease (SD) and 1 (6%) progressive disease (PD). Two patients in PR at 30 days converted to CR at 90 days, with continuous CR at 180 days; all the 3 patients in SD and 1 out of 5 in PR at 30 days progressed at 90 days. Considering the 9 patients exposed to CPIs before CAR-T, 7 out of 9 were infused and all the 7 infused were evaluable for response: 2 (29%) CR, 4 (57%) PR, with ORR 86%, and 1 (14%) died because of a rapid CNS progression after infusion. Two patients in PR at 30-days converted to CR at 90-days, one with continuous CR at 180 days after CAR-T. Conclusions: In our series of 16 infused patients, axi-cel was effective with an ORR of 75% (CR 44%) at 30-days after CAR-T infusion and ORR of 54% (CR 46%) in the 13 patients evaluable at the median follow-up time (180-days after CAR-T infusion). It is important to note the 4 patients from the original real life cohort never received axi-cel. It is noteworthy that ORR was 86% in patients receiving CPIs before CAR-T and 75% in those not exposed to CPIs. With the limitation of small number, the exposure of immune-checkpoint inhibitors seems not to affect negatively response rate and adverse events.

Abstract Mantle cell lymphoma (MCL) has a poor prognosis. Relapsed/refractory patients must respond to salvage chemotherapy in order to receive potentially curative stem cell transplantation (SCT). A salvage regimen with higher rate of response will offer the patient a better chance of survival. We have previously reported the results of R-HCVAD alternating with R-M-A in frontline therapy of MCL (Blood, 104:40a, 2004, (Abstract #128). The current trial looked at relapsed/refractory MCL patients treated also with R-HCVAD alternating with R-M-A. Since August 2001, the trial has accrued 24 out of a planned number of 41 patients of whom 21 are evaluable for response and survival. Median age was 63 years (range 45–78) and male:female ratio was 5:1. Three patients had received previous R-HCVAD alternating with R-M-A and three patients had failed an autologous stem cell transplant. Immediate therapy prior to the study for the 21 patients included R-HCVAD/SCT (1), CHOPw/wo rituximab (8 patients), cyclophosphamide, vincristine and rituximab (1), fludarabine (1), fludarabine, mitoxantrone, dexamethasone and rituximab (2), fludarabine and cyclophosphamide (1), radiotherapy (2), gemcitabine, mitoxantrone and dexamathasone (1) ifosfamide, carboplatin, etoposide and rituximab (1), Velcade (1), gemcitabine (1), and rituximab (1). The median number of prior regimens was one (range 1–6). Responses to the previous treatment included complete response (CR; 8 patients, 38%), partial response (PR; 6 patients, 29%), and no response or progression (7 patients, 33%). Results of the trial are as follows: Median number of cycles received = 4 (range 1–7), with an overall response rate (ORR) of 95% (43% CR/Cru; 52% PR). 5/5 patients who had progressed through the previous treatment responded (1CR, 4 PR), and 2/2 patients who had no change to the prior therapy responded (2 PR’s). We evaluated 12 cases whose response in our trial was classified as PR and found that in 4 of them it was the best response achieved but another 4 were referred to transplant while the tumor was still responding and in another case treatment was still ongoing. In 3 cases toxicity precluded continuation of therapy. Five (24%) of the patients were consolidated with non-myeloablative allogeneic stem cell transplantation. Sixteen were not transplanted for the following reasons: age (2 patients), lack of donor (5), Progressive disease (2), patient refusal (4), physician’s choice (1), waiting for match (1), and lost to follow up (1). Toxicity after 81 cycles included neutropenic fever (14%), grade 4 neutropenia (58%) and grade 4 thrombocytopenia (53%). The were no deaths due to toxicity. With a median follow-up of 21 months range 5–45 months), the median failure-free survival is 18 months as compared to a median FFS of 9 months response duration with the previous therapy, with no plateau in the curve. Patients who underwent stem cell transplant were censored at the time of transplant. The high response rates achieved R-HCVAD alternating with R-M-A makes this regimen an excellent choice for induction therapy prior to stem cell transplantation.

This phase II study tested the oral mTOR inhibitor everolimus (RAD001, Novartis Pharmaceuticals) in simultaneous two-stage phase II lymphoma studies, including one arm involving Hodgkin lymphoma. The goals were to learn the toxicity profile and to assess the anti-tumor response. A total of 17 patients with Hodgkin lymphoma were enrolled in the uncommon arm at completion of enrollment. Methods: Patients (pts) received 10 mg PO daily for each 28 day cycle (up to 12, with a possible extension in responders) and restaged after 2, 6, and 12 cycles. The primary endpoint is the confirmed response rate, including CR, CRu or PR. Results: The median age of the 17 pts with Hodgkin lymphoma was 37 yrs (range: 27–68), with a median of 6 (range, 4–14) prior therapies. Fourteen pts (82.4%) had a prior stem cell transplant (SCT). Pts completed a median of 6 (range, 1–13) cycles of therapy. Fifteen of 17 patients were evaluable for response as of this analysis. The overall response rate was 47% (7/15), all partial responses. Ten patients are continuing on study while 6 have gone off due to disease progression and 1 due to other reasons. Common grade 3 adverse events (AEs) include thrombocytopenia (5 pts), anemia (5 pts) and alkaline phosphatase elevation (1 pts). 1 patient was reported to have grade 4 neutropenia. Conclusions: Oral everolimus has promising activity with acceptable toxicity in Hodgkin lymphoma. These results provide the rationale for additional studies with this novel class of agents and to integrate mTOR inhibitors into salvage treatment regimens for Hodgkin lymphoma.

Abstract Introduction: Multiple myeloma (MM) is a plasma-cell malignancy and overall survival for patients who have relapsed after initial therapy is approximately 2 years. Bortezomib (VELCADE TM) is a first-in-class proteasome inhibitor that has demonstrated significant anti-tumor activity in MM patients. Here we report the results of an observational study of the efficacy and safety of bortezomib-based regimens in Chinese relapsed/refractory MM patients. Methods: This was a multi-center, open-label, phase IV observational study designed to enroll 550 patients with relapsed or refractory MM. From Mar 2006 to May 2008, 500 patients with relapsed or refractory MM were enrolled from 43 medical centers in China and 395 of them were evaluated. Bortezomib (0.7 to 1.6 mg/m2 i.v.) was given on days 1, 4, 8, and 11 in in a 21-day cycle, up to a maximum of 8 cycles, combined with other agents, mainly with the addition of dexamethasone (60.1%). Major endpoint included response rate, safety and time to response. Responses of 62% patients were determined by European Group for Blood and Marrow Transplantation criteria (EBMT). Bortezomib withheld if patients developed neutropenia fever, grade 4 haematologic adverse events (AEs), or grade 3 non-haematologic AEs, and re-administered at 75% of the initial dosage after recovery. Results: In 395 evaluable cases, the median age was 59 years (range 35–82) and the male/female ratio was 1.5:1. 90% of patients were in late stage(stage II/III) and 50% of them were IgG subtype. Patients had received various prior therapies before bortezomib treatment, including VAD (31.3%), VBMCP (M2, 15.1%) and thalidomide-based regimens(14.9%), with best response rate of 10.4% complete response (CR) and 42.3% partial response (PR) from prior therapies. 311 (82%) cases of patients received 1.0–1.4mg/m2 bortezomib-based regimens treatment and 38.5% of them received at least 4 cycles of treatment. 364 patients were evaluable for response, the overall response rate was 287/364 (78.8%), 89 patients (24.5%) achieved a CR, 30(8.24%) had a nearly complete response (nCR), 168 (46.2%) had a PR, 39 (10.7%) had minimal response (MR), 24 (6.6%) had stable disease (SD), and the other 14 (3.9%) had progressive disease (PD). Median time to response was 1 cycle of treatment (range 1–6). Patients who received 4 or more cycles of bortezomib treatment achieved a higher response rate (CR+PR: 81.5%) compared to those who received fewer cycles (partly due to adverse events). And prognosis-related analysis showed that the dosage of bortezomib at 1.0 mg/m2 or more had a significant influence on the time to response and response rate, but no obvious effect on response duration, time to progress or the survival time. Drug related adverse events (AEs) were reported in 50.4% of patients during treatment, including hematologic AEs (mainly thrombocytopenia, 22.5%), gastrointestinal AEs (24.8%), and peripheral neuropathy (22.5%). The rates of grade 3–4 AEs of them were 46.1%, 11.2% and 15.7%, respectively. Serious AEs occurred in 33 (8.4%) cases and 23 (70%) patients recovered finally. Most AEs were predictable and manageable. Conclusion: Bortezomib-based regimen is effective treatment with higher response rate and is well tolerated in most Chinese patients with relapsed and refractory MM patients. Long-term follow-up is continuing.
