Multiple Myeloma (MM) is a morbid disease associated with a poor outcome and while current therapies with new drugs have improved survival, MM still remains incurable in most patients. The only potential curative treatment remains allogeneic Hematopoietic stem cell transplant (HSCT), as shown by our cohort of 92 newly diagnosed patients who received a sibling tandem auto-allo (HSCT) with an estimated 10-year progression free survival (PFS) of 43%. However, the high incidences of toxicities including chronic graft-versus-host-disease (GVHD) (up to 79%) and disease progression (up to 49%) impair improvement in cure rate. Using umbilical cord blood (CB) as an alternative source of hematopoietic stem cells (HSC) could be superior biologically because of their increased proliferative capacity, greater number of progeny with longer telomeres and better anti-tumor efficacy in presence of positive residual disease. Moreover, using CB has been shown to decrease incidence of chronic GVHD. However, CBs have the disadvantage of having a limited HSC dose leading to prolonged cytopenia and higher risk of infections. In a first in-human trial using CB expanded with the ECT-001 (UM171) molecule (clinicaltrial.gov # NCT02668315), the median net expansion of HSC was 36 fold, which allows for the selection of better HLA matched CB regardless of their lower HSC dose. Moreover, the ECT-001 expanded CBs have a different cell composition than regular CBs, with more than 25% of dendritic cell precursors. This, combined to better HLA matched CBs, may reduce chronic GVHD incidence and improve immune reconstitution. To date, 22 patients received an ECT-001 expanded CB and the procedure proved to be safe and feasible. In this new trial, the goal is to evaluate the safety and efficacy of ECT-001 expanded CB transplant in high risk MM patients.
The intended study is designed as a a phase IV pragmatic multicenter randomized controlled clinical trial, comparing the impact of two different therapies including ASA vs. Rivaroxaban in newly diagnosed or relapsed and refractory multiple myeloma patients treated with Lenalidomide Dexamethasone (Len-Dex) combination therapy. The pilot feasibility study was conducted in preparation for this randomized controlled trial designed to assess the effect of an intervention.
The investigators will track 250 multiple myeloma patients across Canada over time, using new lab tests to evaluate their blood and bone marrow, as they receive standard of care treatment. The main hypothesis is that these tests will allow clinicians to better diagnose and manage multiple myeloma, improving patients' quality of life overall.
This phase I/II trial studies the side effects and best dose of melphalan hydrochloride in treating participants with newly-diagnosed multiple myeloma who are undergoing a donor stem cell transplantation. Giving chemotherapy before a donor stem cell transplantation helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the participant, they may help the participant's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving melphalan hydrochloride before a donor stem cell transplantation may work better than standard chemotherapy in helping to prevent multiple myeloma from coming back.
Multiple Myeloma (MM) is a morbid disease which can only be cured with an allogeneic hematopoietic stem cell transplant (HSCT). Approximately 50% of allotransplanted patients will relapse, with a median survival of 5 years. Better approaches to improve disease control at relapse, while decreasing toxicity, are urgently needed. Relapse after allogeneic transplant is a failure of the graft versus MM effect (GvMM). DLIs can be used to control disease following relapse, but the optimal dose, schedule of administration and drug association remain elusive, while the immunosuppression found in MM patients can compromise their effect. One reason for immunotherapy failure relates to the immunological environment: as much as myeloma cells depend on their microenvironment to survive and proliferate, the immunotherapeutic effect of allogeneic HSCT depends on both systemic and local immunological status to be efficacious. Immunomodulatory drugs such as Lenalidomide (Len) have been tried in various settings after allogeneic transplantation with the aim to reverse immunosuppression and stimulate the GvMM, but if and how Len influences a GvMM and thereby promotes an immunotherapeutic success remained uncharacterized. Therefore, a deeper understanding of the immunological environment in MM patients is needed in order to establish and / or restore a potent GvMM effect. This study proposes the powerful combination of the two following goals, one clinical and one biological : 1. Clinical: The investigators propose a two-step treatment using first Len in association with Dexamethasone (Dex), followed by Donor Leukocytes Infusions (DLIs) to offer an optimal disease control strategy in relapsed patients. The cytoreductive and immunomodulatory effects of Len is expected to induce a permissive immunological environment for the immunotherapeutic activity of DLIs to develop, while the association with Dex will lessen the risk of graft-versus-host disease (GVHD). This treatment combination has the potential to further improve depth of myeloma response, delay myeloma progression and improve patient survival. 2. Biological: In an attempt to gain knowledge on how the GvMM behaves in MM patients post-relapse after having received a combined treatment of Len/Dex/DLIs, the investigators propose to characterize the immune environment of their bone marrow (BM) using both minimal residual disease (MRD) assessement by flow cytometry and an unbiased analysis of the transcriptome at various time points.
A single arm, open-label pilot study is designed to determine the safety, efficacy and cytokinetics of CAR-BCMA T cells in patients with BCMA-positive refractory or relapsed multiple myeloma.
This study will evaluate the efficacy and safety of 3-drug all-oral combination, ixazomib plus lenalidomide plus dexamethasone (IRd) as induction treatment for autologous stem cell transplantation eligible patients followed by IRd consolidation and risk based maintenance treatment with IR or R alone.
This study seeks to determine whether addition of an allogeneic myeloma vaccine can augment clinical responses to lenalidomide in patients with near complete remission (nCR), or complete remission (CR) leading to a significant improvement in progression-free survival.This main objective of this study is to compare the 2-year progression free survival of patients with multiple myeloma in CR or nCR, treated with lenalidomide plus an allogeneic myeloma vaccine in combination with lenalidomide (with or without Prevnar vaccine) or versus placebo in combination with lenalidomide (control arm).
This is an open-label, multi-center, international, Phase 1/2 study to assess the safety, PK and efficacy of CC-92480 monotherapy and in combination with dexamethasone in subjects with relapsed and refractory multiple myeloma (RRMM). All eligible subjects must be previously treated with at least 3 prior regimens including lenalidomide, pomalidomide, a proteasome inhibitor and an anti-CD38 antibody and be refractory to their last line of therapy.
