Trial Summary
What is the purpose of this trial?This phase III trial compares the effect of adding a stem cell transplant with melphalan after completing chemotherapy with daratumumab, cyclophosphamide, bortezomib and dexamethasone (Dara-VCD) versus chemotherapy with Dara-VCD alone for treating patients with newly diagnosed amyloid light chain (AL) amyloidosis. Melphalan is a chemotherapy given prior to a stem cell transplant. Giving chemotherapy before a peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. The stem cells are then returned to the patients to replace the blood forming cells that were destroyed by the chemotherapy. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Chemotherapy drugs, such as cyclophosphamide and bortezomib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Dexamethasone is in a class of medications called corticosteroids. It is used to lower the body's immune response to help stop the growth of cancer cells. Giving a stem cell transplant with melphalan after Dara-VCD may kill more cancer cells in patients with newly diagnosed AL amyloidosis.
Do I need to stop my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications. However, you may continue taking chronic corticosteroids if they are for conditions other than AL amyloidosis or myeloma. It's best to discuss your specific medications with the study team.
What data supports the effectiveness of the drug Daratumumab for treating AL amyloidosis?
Research shows that Daratumumab, when used alone or with other drugs, significantly improves blood and organ responses in patients with AL amyloidosis. It has been effective in both newly diagnosed and previously treated patients, with studies showing high rates of response and good tolerability.
12345Is the combination of chemotherapy and stem cell transplant for amyloidosis safe?
Daratumumab, when used in combination with other chemotherapy drugs for treating amyloidosis, has been shown to have a tolerable safety profile with no significant treatment-related adverse events reported in multiple studies. It is generally well tolerated, and no new safety concerns were identified compared to its use in other conditions.
12367How is the drug Daratumumab used in treating amyloidosis different from other treatments?
Daratumumab, when combined with other drugs like bortezomib, cyclophosphamide, and dexamethasone, offers a unique treatment for amyloidosis by targeting a specific protein (CD38) on cells, leading to improved blood and organ responses. This combination is particularly effective for patients who are newly diagnosed or have relapsed, providing a promising option with a good safety profile compared to traditional treatments.
12368Eligibility Criteria
This trial is for adults with newly diagnosed AL amyloidosis, confirmed by specific tests like urine and serum immunofixation electrophoresis, bone marrow analysis, and biopsy. Participants must have a certain level of light chain difference in their blood and can have had up to one cycle of prior therapy. They should be able to perform daily activities on their own or with some effort (ECOG score 0-2) but may be less mobile due to neuropathy.Inclusion Criteria
My diagnosis of AL amyloidosis is confirmed by biopsy and specific tests.
My bone marrow has cancerous cells and my blood test shows a specific protein imbalance.
I am willing to undergo high dose chemotherapy and stem cell transplant if required.
Participant Groups
The study compares adding stem cell transplant after Dara-VCD chemotherapy (daratumumab, cyclophosphamide, bortezomib, dexamethasone) versus just the chemotherapy for treating AL amyloidosis. The goal is to see if the transplant helps kill more cancer cells when combined with melphalan chemo.

Progress in research: Daratumumab improves treatment outcomes of patients with AL amyloidosis. [2021]Outcomes for patients with systemic light-chain (AL) amyloidosis have improved over the last two decades with timely diagnosis, use of novel chemotherapeutic agents, risk stratification and better patient selection criteria before hematopoietic autologous stem cell transplant (ASCT). However, majority of patients have advanced stage disease at initial presentation and at relapse rendering them ineligible for intensive cytotoxic chemotherapy or ASCT. Daratumumab (Dara) with or without standard chemotherapy appears to be an excellent treatment option for newly diagnosed and relapsed refractory AL amyloidosis. This is largely due to its tolerable safety and remarkable efficacy as seen in multiple retrospective, small phase II studies as well as a phase III randomized controlled trial. Here we review published clinical trials and retrospective data of Dara in AL amyloidosis that explore its role as a valuable addition to the treatment armamentarium for this challenging disease.
Daratumumab: A Review in Newly Diagnosed Systemic Light Chain Amyloidosis. [2022]Subcutaneous daratumumab (DARZALEX®) co-formulated with recombinant human hyaluronidase (DARZALEX FASPRO®) is approved in several countries, including the USA and those of the EU, for use in combination with bortezomib, cyclophosphamide and dexamethasone for the treatment of adult patients with newly diagnosed light chain (AL) amyloidosis. Daratumumab is a CD38-targeting, human IgG1κ monoclonal antibody. In the pivotal phase III ANDROMEDA trial in adults with newly diagnosed systemic AL amyloidosis, the addition of daratumumab to bortezomib, cyclophosphamide and dexamethasone significantly increased the proportion of patients achieving a haematological complete response relative to bortezomib, cyclophosphamide and dexamethasone alone (primary endpoint). Daratumumab combination therapy produced rapid and deep haematological responses which were associated with improved major organ deterioration progression-free survival (PFS). The addition of daratumumab also led to higher cardiac and renal response rates at 6 and 12 months. Daratumumab had an acceptable tolerability profile when used as combination therapy. Therefore, daratumumab in combination with bortezomib, cyclophosphamide and dexamethasone represents an important emerging first-line treatment option for patients with systemic AL amyloidosis.
Efficacy and Safety of Daratumumab-based Regimens in Pretreated Light Chain (AL) Amyloidosis: A Systematic Review. [2022]With recent advances in novel chemotherapeutic agents and increasing use of autologous hematopoietic stem cell transplant, there has been a significant improvement in outcomes for patients with AL Amyloidosis. Daratumumab, with its excellent safety and efficacy profile, appears to be an ideal treatment option for patients with newly diagnosed as well as relapsed refractory AL amyloidosis. In this systematic review, we analyzed the published literature on the role of Daratumumab in pretreated relapsed and refractory AL-amyloidosis patients using PubMed, Embase, Cochrane, and clinicaltrials.gov databases. A total of 16 studies evaluated the role of Daratumumab as monotherapy (DMT) or in combination with other chemotherapeutic agents (DCT). DMT and DCT were associated with promising efficacy with hematologic and organ responses (cardiac/renal) seen in 50%-90% and 50%-80% of the patients, respectively. Daratumumab appeared to be well tolerated with no significant treatment-related adverse events as DMT or DCT.
Daratumumab for the treatment of AL amyloidosis. [2023]Autologous stem cell transplantation (ASCT) has been used as treatment for immunoglobulin light-chain (AL) amyloidosis for over two decades with improving outcomes; however, the majority of patients are not candidates for this therapy at diagnosis. Novel agents such as immunomodulatory drugs, proteasome inhibitors, and immunotherapy with monoclonal antibodies targeting CD38 have been adopted from the multiple myeloma spheres with encouraging results. Herein, we discuss the role of daratumumab, a monoclonal antibody to CD38, in the treatment of AL amyloidosis. We focus on its mechanism of action, tolerability, and the current published data on its use in AL amyloidosis. Early data from phase I and phase II studies show that daratumumab is tolerated well in this population and induces rapid and deep responses. Phase III trials are currently accruing and we envision daratumumab becoming a key component in the treatment of AL amyloidosis in the future.
High rate of profound clonal and renal responses with daratumumab treatment in heavily pre-treated patients with light chain (AL) amyloidosis and high bone marrow plasma cell infiltrate. [2020]Daratumumab demonstrated activity in the treatment of AL amyloidosis in two recently concluded phase II clinical trials in relapsed and refractory patients. Its role in upfront therapy is under evaluation in a phase III study. In this report we evaluated the safety and efficacy of 28-day cycles of daratumumab (single agent or combined with bortezomib or lenalidomide) in 72 previously treated patients with multiple myeloma and AL amyloidosis. Fifty (69%) were refractory to the last line of therapy. After eight infusions of daratumumab, 59 patients (82%) achieved a hematologic response, with 12 (16%) complete responses (CRs) and 30 (42%) very good partial responses (VGPRs). After 16 infusions, the quality of response improved with 22 patients (30%) achieving CR and 21 (29%) attaining VGPR. Cardiac response was observed in 11 of 37 evaluable patients (29%) and renal response in 23 of 38 patients (60%). Daratumumab is highly effective in heavily pretreated patients with relapsed/refractory AL amyloidosis and high bone marrow plasma cell burden. Renal responses, which are usually rare in this setting, were frequently observed.
Daratumumab plus CyBorD for patients with newly diagnosed AL amyloidosis: safety run-in results of ANDROMEDA. [2021]Although no therapies are approved for light chain (AL) amyloidosis, cyclophosphamide, bortezomib, and dexamethasone (CyBorD) is considered standard of care. Based on outcomes of daratumumab in multiple myeloma (MM), the phase 3 ANDROMEDA study (NCT03201965) is evaluating daratumumab-CyBorD vs CyBorD in newly diagnosed AL amyloidosis. We report results of the 28-patient safety run-in. Patients received subcutaneous daratumumab (DARA SC) weekly in cycles 1 to 2, every 2 weeks in cycles 3 to 6, and every 4 weeks thereafter for up to 2 years. CyBorD was given weekly for 6 cycles. Patients had a median of 2 involved organs (kidney, 68%; cardiac, 61%). Patients received a median of 16 (range, 1-23) treatment cycles. Treatment-emergent adverse events were consistent with DARA SC in MM and CyBorD. Infusion-related reactions occurred in 1 patient (grade 1). No grade 5 treatment-emergent adverse events occurred; 5 patients died, including 3 after transplant. Overall hematologic response rate was 96%, with a complete hematologic response in 15 (54%) patients; at least partial response occurred in 20, 22, and 17 patients at 1, 3, and 6 months, respectively. Renal response occurred in 6 of 16, 7 of 15, and 10 of 15 patients, and cardiac response occurred in 6 of 16, 6 of 13, and 8 of 13 patients at 3, 6, and 12 months, respectively. Hepatic response occurred in 2 of 3 patients at 12 months. Daratumumab-CyBorD was well tolerated, with no new safety concerns versus the intravenous formulation, and demonstrated robust hematologic and organ responses. This trial was registered at www.clinicaltrials.gov as #NCT03201965.
Population Pharmacokinetics and Exposure-Response Modeling of Daratumumab Subcutaneous Administration in Patients With Light-Chain Amyloidosis. [2022]The purpose of this study is to characterize the population pharmacokinetics (popPK) of subcutaneous (SC) daratumumab in combination with bortezomib, cyclophosphamide, and dexamethasone and explore the relationship between daratumumab systemic exposure and selected efficacy and safety end points in patients with newly diagnosed systemic amyloid light-chain amyloidosis. The popPK analysis included pharmacokinetic and immunogenicity data from patients receiving daratumumab SC in combination with bortezomib, cyclophosphamide, and dexamethasone in the ANDROMEDA study (AMY3001; safety run-in, n = 28; randomized phase, n = 183). Nonlinear mixed-effects modeling was used to characterize the popPK and quantify the impact of potential covariates. The exposure-response (E-R) analysis included data from all patients in the randomized phase of ANDROMEDA (n = 388). Logistic regression and survival analysis were used to evaluate the relationships between daratumumab systemic exposure and efficacy end points. The E-R analysis on safety was conducted using quartile comparison and logistic regression analysis. The observed concentration-time data of daratumumab SC were well described by a 1-compartment popPK model with first-order absorption and parallel linear and nonlinear Michaelis-Menten elimination pathways. None of the investigated covariates were determined to be clinically meaningful. Daratumumab systemic exposure was generally similar across subgroups that achieved different levels of hematologic response, and there was no apparent relationship between daratumumab systemic exposure and the investigated safety end points. In conclusion, the popPK and E-R analyses supported the selected 1800-mg flat dose of daratumumab SC in combination with the bortezomib, cyclophosphamide, and dexamethasone regimen for the treatment of light-chain amyloidosis. No dose adjustment was recommended for investigated covariates.
The Role of Autologous Stem Cell Transplantation in Amyloidosis. [2022]Autologous stem cell transplantation (ASCT) has been an essential part of the treatment armamentarium in light chain (AL) amyloidosis for several decades. Patients who achieve a complete hematologic response following ASCT have a long overall survival. However, only 1 randomized controlled trial compared ASCT with the standard of care used at the time, which was melphalan and dexamethasone, and the results did not support the use of ASCT in AL amyloidosis. These results are of limited significance due to the unexpected high transplant-related mortality (TRM) (24%). TRM is a major concern in AL amyloidosis, but its incidence can be lessened by better patient selection and by patients receiving ASCT in specialized centers. ASCT in AL amyloidosis is performed only in selected patients; approximately 20% of patients with AL amyloidosis are transplant eligible up front or after bortezomib (Velcade) based conditioning. The introduction of newer agents such as bortezomib and daratumumab (Darzalex), which lead to deep responses and have good safety profiles, encourage revisiting the benefit and timing of ASCT in the modern era. This review provides a comprehensive assessment of eligibility criteria for ASCT in AL amyloidosis, conditioning dosing, efficacy in terms of hematologic and organ response, and future areas of research.
