Abstract Melphalan-prednisone (MP) combination has been considered a standard of care for front line treatment of multiple myeloma in patients non eligible for transplant. Melphalan-prednisone-bortezomib (MPV) combination has been approved in the United States in patients non eligible for high-dose chemotherapy (HD-C) and has recently received a positive opinion from the CHMP in Europe. Melphalan-prednisone-thalidomide (MPT) was approved in Europe in patients >65 or not eligible for HD-C. There is no head-to-head trial directly comparing MPV to MPT. The objective of the current study was to compare the efficacy of MPV to MP and MPT as first line treatment of multiple myeloma in patients non eligible for transplant. Six randomized placebo controlled trials investigating the efficacy of MPT (5) and MPV (1) relative to MP were identified with a systematic literature review. The endpoints of interest were overall survival (OS), progression free survival (PFS) and overall and complete response. Relative efficacy estimates of MPT versus MP as obtained from the MPT-MP trials were combined with meta-analysis techniques and simultaneously indirectly compared with the relative efficacy of MPV versus MP from the MPV-MP trial (VISTA). This adjusted indirect comparison was performed with Bayesian fixed and random effects models. As compared to frequentist approach, Bayesian meta-analysis offers a more informative summary of the likely value of efficacy after observing the data and allows for direct probabilistic inferences. Of the three interventions compared, there was an 81% probability that MPV was the most efficacious intervention in terms of overall response and a >99% probability in terms of complete response. With MPV a patient was two times more likely to show a complete response than with MPT (Relative Risk=2.15; 95%Credible Interval (CrI): 0.99–4.45). Both MPV and MPT showed greater OS than MP (HR=0.61; 95%CrI: 0.42–0.88 and HR=0.61; 95%CrI: 0.47–0.78 respectively); the indirect comparison showed similar efficacy in terms of OS between MPV and MPT (MPV vs MPT: Hazard Ratio=1.00; 95%CrI 0.64–1.57). Both MPV and MPT also displayed greater PFS than MP (MPV versus MP: HR=0.61; 95%CrI 0.49–0.76 and MPT versus MP HR=0.51; 95%CrI 0.41–0.63 respectively) and showed similar efficacy (MPV vs MPT: HR=1.19; 95%CrI: 0.87–1.63). In this study, both MPV and MPT are more efficacious than MP in terms of response, PFS and OS. MPV is expected to result in a greater complete and overall response than MPT. No difference in OS or PFS was displayed. Further analyses will need to be undertaken once evidence base data is more mature.

Abstract Introduction: Although highly effective agents and novel therapeutic strategies are being developed, high-dose chemotherapy followed by autologous stem cell transplantation (HDT/ASCT) has not been overcome in the first-line treatment for fit patients (pts) with multiple myeloma. The objective of this work is to retrospectively analyze the use of this procedure in newly diagnosed Czech patients. Methods: Data were derived using the Czech Myeloma Group Registry of Monoclonal Gammopathies. By February 2 nd 2021, a total of 2154 newly diagnosed multiple myeloma patients who underwent HDT/ASCT were identified. Results: At the time of multiple myeloma diagnosis, the median age was 59 years; 24%/56%/14%/5%/1% pts were ECOG 0/1/2/3/4; 44%/32%/24% pts were ISS stage I/II/III; 14.5%/17.5%/68% and 84%/16% pts were Durie-Salmon stage I/II/III and subclassification A/B, respectively. The combinations of agents used in the induction regimen were proteasome inhibitor (PI), immunomodulatory drug (IMiD) and glucocorticoid (GC) in 28.5% (613/2154) pts; PI, GC and chemotherapy (CHT) in 24.8% (534/2154) pts; GC and CHT in 22,5% and IMiD, GC and CHT in 16.1% (346/2154). Other combination of drugs was used in 8.2% (177/2154) pts. It was registered that 3.7% (79/2154) induction regimens were switched to a different combination because of toxicity, patient's choice, poor peripheral venous access or other reasons. Single HDT/ASCT was performed in 77.3% (1665/2154) cases whereas tandem HDT/ASCT was given to 11.8% (254/2154) patients. In 10% (215/2154) cases, the transplantation technique was not specified. Nine percent (193/2154) patients were treated within a clinical study. The median progression free survival (mPFS) and the median overall survival (mOS) of the whole cohort was 28.9 and 92.1 months, respectively. Information about response to treatment before and after the high-dose therapy were available for 75.7% (1627/2154) and 92.2% (1987/2154) patients, respectively. Disease status at the time of HDT/ASCT was defined as stringent complete response (sCR) at 2.2% (36/1627), complete response (CR) at 11.9% (194/1627), very good partial response (VGPR) at 38.2% (621/1627), partial response (PR) at 40.9% (666/1627), minimal response (MR) at 3.6%, (58/1627), stable disease (SD) at 2.2% (36/1627), progressive disease (PD) at 1% (16/1627) patients. The overall response rate (ORR) on day 100 was 92.8% (sCR: 10.5% [209/1987], CR: 22.4% [446/1987], VGPR: 35% [696/1987], PR: 24.8% [493/1987], MR: 2.7% [54/1987], SD: 1.4% [27/1987], PD: 3.1% [62/1987]). We also performed a survival analysis of patients progressing up to 18 months after HDT/ASCT (n=1219) versus patients progressing in more than 18 months (n=935). The median OS was 41.5 versus 124.9 months, respectively. An analysis of the role of tandem HDT/ASCT in this real-world cohort will be presented at the conference. Conclusion: Globally as well as in the Czech Republic, HDT/ASCT is an important therapeutic approach in the first-line treatment of multiple myeloma. Our analysis of 2154 newly diagnosed transplant-eligible patients confirms high effectiveness - ORR of 92.8%, mPFS of 28.9 months, and long-term survival reaching mOS of 92.1 months.

Abstract Background Induction triplets utilizing at least one of the “novel drugs” and steroids with or without chemotherapy are considered current standard of care in newly diagnosed, symptomatic multiple myeloma (MM). Medically fit patients (pts) remain candidates for subsequent autologous (auto) stem cell transplant (SCT) while use of allogeneic (allo) SCT remains a matter of debate. As we had previously shown the RAD regimen to be well tolerated and highly effective in relapsed and relapsed/refractory MM, we evaluated this combination in first-line treatment. Methods The current phase II trial (DSMM XII) was designed to include a total of 190 pts up to 65 years of age with symptomatic MM. Four 4-week cycles of RAD (lenalidomide 25 mg/day, d 1-21; adriamycin 9 mg/m² as 24-hour infusion, d1-4; oral dexamethasone 40 mg, d1-4 and 17-20; pegfilgrastim 6 mg, d 6) preceded stem cell chemomobilization. Low-molecular weight heparin for prophylaxis of venous thromboembolic events (VTE) was mandatory. Pts received either tandem auto SCT (melphalan 200 mg/m²; Mel200) or auto followed by allo SCT. Allo SCT (preparative regimen: treosulfan/fludarabine) was reserved for pts featuring at least one cytogenetic or serologic risk factor who had a matched sibling or unrelated donor available. Lenalidomide maintenance was administered for one year following both tandem auto and auto/allo SCT. This is the second pre-planned interim safety and efficacy analysis. Results Eighty-nine pts with a median age of 54 (range, 30-65) years, who were recruited between August 2009 and October 2010, are evaluable. Fifty pts (56.2%) had ISS stage II/III disease and in all except three, molecular cytogenetic analysis was performed. Incidences of chromosomal abnormalities were as follows: deletion of (del) 13q, 24.7%; translocation t(4;14), 12.4%; t(14;16), 3.4%; and del 17p, 5.6%. Treatment-related mortality with RAD induction was 0% while 61.8% of pts had treatment-emergent SAEs. Seventeen pts (19%) experienced neutropenia of grades 1 to 4. Incidences of severe (grades 3/4) and febrile neutropenia were 5.6 and 1%, respectively. Seven pts each (8%) had pneumonia and VTE, respectively. Post-RAD-induction CR/sCR and at least VGPR rates were 9% and 47.2%, respectively. All 78 pts with at least stable disease successfully mobilized stem cells. Overall response rate (at least partial response, PR) following first SCT on an intention-to-treat basis was 83%. Twelve pts each (13.5%) achieved centrally confirmed complete response (CR) or stringent (s)CR, respectively, and 54 pts (60.7%) had at least very good PR (VGPR). Conclusions This interim analysis shows RAD to be very well tolerated and effective in first line treatment of symptomatic MM. Mel200 further increased rates of deep response (at least VGPR) achieved by RAD induction. We are currently comparing this regimen to bortezomib, lenalidomide and dexamethasone (VRd) in a phase III trial. Disclosures: Knop: Celgene GmbH: Honoraria.

Backgrounds: We performed this systematic review and meta-analysis to compare the efficacy of new-generation tyrosine kinase inhibitors (NG-TKIs; including dasatinib, nilotinib, bosutinib, radotinib, and ponatinib) versus imatinib for patients with newly diagnosed chronic myeloid leukemia (CML). Summary: We identified randomized controlled trials comparing the efficacy of NG-TKIs versus imatinib as the first-line treatment for CML patients by searching the PubMed, Cochrane library, and EMBASE databases. Two reviewers independently extracted data and assessed study quality. A meta-analysis was performed to calculate risk ratios and 95% CIs using a fixed-effects model.Our study included 10 trials. Overall, treatment with NG-TKIs significantly improved the major molecular response and MR4.5 at all time points, and early molecular response at 3 months. Importantly, overall survival (OS) was significantly higher with the NG-TKIs at 12 months. Besides, NG-TKI-treated patients showed a significantly lower CML-related death and progression to the accelerated phase/blast crisis. Key Messages: In first-line treatment, NG-TKIs are superior to imatinib regarding OS at 12 months, and because molecular response rates were higher with the NG-TKIs at all time points, the NG-TKIs favor treatment-free remission.

Abstract Abstract 3967 Background Triple combinations utilizing dexamethasone, at least one of the “novel drugs” and either an alkylating agent or an anthracycline are currently considered standard induction regimens in newly diagnosed multiple myeloma (MM). In patients (pts) deemed medically fit, subsequent autologous (auto) stem cell transplantation (SCT) yet is a mainstay of care. Whether allogeneic (allo) SCT in first line treatment of MM further improves prognosis remains, however, a matter of debate. We have shown the RAD regimen to be highly effective and well tolerated in relapsed and refractory MM. Therefore, we decided to integrate this combination as a means of induction into the up-front management. Patients and methods The current phase-II trial (DSMM XII) was designed to include pts up to the age of 65 years with newly diagnosed, symptomatic MM. We chose four cycles of RAD induction (lenalidomide 25 mg/day d 1–21; infusional adriamycin 9 mg/m2 and day d1-4; dex 40 mg d1-4 and 17–20; pegfilgrastim 6 mg d 6) every 4 weeks followed by chemomobilization (cyclophosphamide, etoposide) of peripheral blood stem cells. Thromboprophylaxis by low molecular weight heparin is mandatory. All pts are scheduled to receive two transplants, the first of which being an auto SCT following standard high-dose melphalan (200 mg/m2). A subsequent allo SCT after preparation with treosulfan/fludarabin is scheduled for pts featuring at least one cytogenetic or serologic risk factor (RF). Those without any RF (“very favourable risk”) are to proceed to a second auto SCT. All patients will receive 12 months of lenalidomide maintenance. The primary end point of this trial is response to risk-adapted transplant as assessed after second SCT. This is the first planned efficacy interim analysis after 50 pts having terminated induction treatment. Results 148 pts with a median age of 55.5 (range, 30–66) years have been enrolled by 16 German centers between 9/2009 and 7/2011. In addition to the intended sample size, 2 pts had progressive disease for a total of 52 pts being evaluable for post-induction response according to the IMWG criteria. 32 pts (62%) had ISS stage II and III disease and all except three were evaluable for cytogenetic analysis based on fluorescence in situ hybridization (FISH). Incidences of chromosomal abnormalities were as follows: deletion of 13q, 31%; translocation (4;14), 15%; and deletion of 17p, 12%. Overall response rate was 79% including a 52% rate of at least very good partial response (VGPR). Seven pts (13%) achieved confirmed complete response (CR) and stringent CR. 18/52 pts (35%) experienced severe treatment-emergent adverse events (t-SAEs) with an incidence of hematologic events of 4%. Incidences of infections and venous thromboembolism were 8% and 6%, respectively. Conclusions Results from this interim analysis indicate RAD to be a very effective and well tolerated induction protocol in newly diagnosed MM. High-quality response (VGPR or better) to induction is known to be a major prognosticator for long-term prognosis in a given patient. Thus, combination of RAD with risk-adjusted SCT may contribute to enhanced disease control in a substantial proportion of pts. Disclosures: Knop: Celgene Germany GmbH: Consultancy.
