OBJECTIVESThis study aims to assess the impact of the nationwide Omicron outbreak in December 2022 on Chinese patients with plasma cell disorders (PCD), focusing on the clinical characteristics of PCD patients with COVID-19 and the risk factors contributing to adverse clinical courses (severity and hospitalization) and outcomes.METHODSA multicenter retrospective study was performed from December 1, 2022, to January 19, 2023. The study population includes 404 PCD patients, divided into a COVID-19 group (n = 342) and an uninfected group (n = 62).RESULTSThe frequency of COVID-19 infection was 84.7% (342/404), and 16.4% (56/342) were severe COVID-19. Among the 277 patients with complete follow-up, 2 deaths (0.7%) were reported, while 231 (83.4%) recovered from COVID-19. Age > 65 (P = 0.02) and prior anti-CD38 monoclonal antibody (mAb) treatment within six months (P = 0.03) were independent risk factors for severe infection. Additionally, previous chimeric antigen receptor T-cell (CAR-T) therapy within six months was correlated with a higher risk of hospitalization (P = 0.04) and prolonged recovery time (P = 0.03). No significant protective effect of vaccination on infection or severe infection was observed (P > 0.05).CONCLUSIONSThe latest Omicron outbreak results in higher rates of severe infection and mortality in PCD patients compared with the general population in China, highlighting the need to protect this vulnerable population during the pandemic. Recent use of anti-CD38 mAb and CAR-T therapy are associated with poorer clinical courses and outcomes of PCD patients with COVID-19.

Characterising how a single bout of exercise in people with myeloma affects clonal plasma cell and immune effector cell frequency in blood, and daratumumab efficacy in vitro

Article

Author: Murray, James ; Brown, Frankie F ; Oliver, Rebecca ; Turner, James E ; Collier-Bain, Harrison D. ; Collier-Bain, Harrison D ; Moore, Sally ; Graby, John ; Campbell, John P ; Eddy, Rachel ; Leach, Shoji ; Augustine, Daniel ; Emery, Annabelle ; Crowe, Josephine ; Causer, Adam J. ; Brown, Frankie F. ; Causer, Adam J ; Turner, James E. ; Campbell, John P.

Multiple myeloma is a haematological cancer characterised by the accumulation of clonal plasma cells in the bone marrow and is commonly treated with daratumumab, an anti-CD38 monoclonal antibody immunotherapy. Daratumumab often fails to induce stringent complete responses, due in part to resistance to antibody-dependent cellular cytotoxicity (ADCC) exerted by natural killer (NK)-cells and monocytes. Exercise bouts undertaken by healthy people induce lymphocytosis in blood, including to NK-cells and B-cells, but the effects of exercise are unknown in myeloma patients. In addition, whether exercise mobilises plasma cells has not been adequately investigated, and as such the potential impact of exercise on daratumumab treatment is unclear. In this exploratory pilot study, n = 16 smouldering multiple myeloma participants enrolled and n = 9 completed the study which comprised a bout of cycling 15% above anaerobic threshold for ∼30-min, with blood samples collected pre-, immediately post-, and 30-min post-exercise. Peripheral blood mononuclear cells were isolated from blood samples and incubated with the RPMI-8226 plasmacytoma cell line, with or without the presence of daratumumab to determine specific lysis using a calcein-release assay. Daratumumab-mediated cell lysis increased from 18.8% to 23.2% pre- to post-exercise, respectively (p < 0.001), owing to an increased frequency of CD3^-CD56⁺CD16⁺ NK-cells (+348%), HLA-DR⁺CD14^dimCD16⁺ monocytes (+125%), and HLA-DR⁺CD14⁺CD32⁺ monocytes (+41%) in blood (p < 0.01). However, overall, total plasma cells (CD38⁺CD138⁺) nor clonal plasma cells (CD38^brightCD138⁺CD45^-/dimCD19^- with light-chain restriction) increased in blood (p > 0.05). Notably, we observed a 305% increase in NK-cells expressing CD38, the daratumumab target antigen, which might render NK-cells more susceptible to daratumumab-mediated fratricide - whereby NK-cells initiate ADCC against daratumumab-bound NK-cells. In conclusion, exercise modestly improved the efficacy of daratumumab-mediated ADCC in vitro. However, plasma cells were largely unchanged, and NK-cells expressing CD38 - the daratumumab target antigen - increased in blood. Future research should consider the optimal timings of exercise during daratumumab treatment in myeloma to avert exacerbation of daratumumab-mediated NK-cell lysis.

ABSTRACTBackgroundIn the era of novel agents, the clinical outcomes of induction treatment and the impact of the number of high‐risk cytogenetic abnormalities (HRA) in newly diagnosed multiple myeloma (NDMM) need to be explored.ObjectiveThrough this study, we aim to analyze the effectiveness of different induction treatments and explore the survival outcomes of patients with varying numbers of HRA.MethodsA total of 734 patients from seven medical centers were included in our study.ResultsPatients in the CD38 monoclonal antibody or IMiDs plus proteasome inhibitors (PI) groups had significantly superior overall survival (OS) and progression‐free survival (PFS) compared to those receiving IMiDs or PI alone. Additionally, the CD38 monoclonal antibody conferred a PFS advantage over IMiDs plus PI. Patients with ≥ 2 high‐risk cytogenetic abnormalities (HRA) exhibited an extremely poor prognosis and should be considered ultra‐high‐risk individuals in multiple myeloma (MM). The CD38 monoclonal antibody, transplantation, and achieving minimal residual disease (MRD) negativity only partly mitigated the poor prognosis in patients with HRA. Furthermore, patients with 1q21 gain/amplification (1q21+) only had a significantly worse prognosis compared to patients without HRA, and those with 1q21+ plus del17p or t(4;14) exhibited an inferior prognosis compared to those with 1q21+ alone.ConclusionOur results suggested that double‐hit multiple myeloma was associated with extremely poor survival outcomes, and more effective treatments needed to be explored for this particular subtype of MM.

Anti-CD38 mAb Market to Accelerate Substantially During the Study Period (2020-2034) Owing to a Strong Uptake of DARZALEX in Multiple Myeloma and Expected Entry of anti-CD38 mAbs in Autoimmune Diseases | DelveInsight

The anti-CD38 mAb market is projected to experience substantial growth in the coming years owing to strong uptake of DARZALEX (along with DARZALEX FASPRO), the expected entry of subcutaneous formulation of SARCLISA in Multiple Myeloma. This growth is also driven by a rising number of cancer and autoimmune disorder diagnoses, as well as an increasing number of Anti-CD38 mAbs undergoing clinical trials and seeking approval. LAS VEGAS, Oct. 23, 2024 /PRNewswire/ -- DelveInsight's Anti-CD38 mAb Market Insights report includes a comprehensive understanding of current treatment practices, emerging anti-CD38 mAb, market share of individual therapies, and current and forecasted anti-CD38 mAb market size from 2020 to 2034, segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. Key Takeaways from the Anti-CD38 mAb Market Report As per DelveInsight's analysis, the total market size of anti-CD38 mAb in the 7MM is expected to surge significantly by 2034. Multiple Myeloma is the only indication for which anti-CD38 therapies, Johnson&Johnson's (J&J) DARZALEX and Sanofi's SARCLISA have been approved until now. Around 50% of DARZALEX usage comes from second-line treatment in Multiple Myeloma. Additionally, in the frontline multiple myeloma clinical trials, DARZALEX has emerged triumphant, surpassing all expectations and solidifying its position as the gold standard of therapy. Its unparalleled effectiveness and exceptional safety profile have exceeded rivals' predictions and soon positioned DARZALEX to dominate the multiple myeloma market. The filing submission of SARCLISA subcutaneous in 3L R/R MM (IRAKLIA) is anticipated in 2025 and beyond. Somehow, SARCLISA is way behind DARZALEX in terms of market expansion, and DARZALEX has also got an early mover advantage of over 4 years. Multiple Myeloma is the leading indication, other emerging indications with commercial opportunity include Systemic Lupus Erythematosus (SLE), Chronic Kidney Disease (CKD), and IgA Nephropathy Leading emerging anti-CD38 mAb companies such as Takeda Pharmaceuticals, HI-Bio, Genmab, CASI Pharmaceuticals, and others are developing novel anti-CD38 mAb that can be available in the market in the coming years. Some of the key anti-CD38 mAb in the pipeline include Mezagitamab (TAK-079), Felzartamab, GEN3014, CID-103 , and others. In June 2024, data from the IMROZ Phase III study by Sanofi demonstrated that SARCLISA is the first anti-CD38 to significantly improve progression-free survival in combination with bortezomib, lenalidomide, and dexamethasone (VRd) for newly diagnosed transplant-ineligible multiple myeloma. In May 2024, Biogen and Human Immunology Biosciences (HI-Bio), announced the companies have entered into a definitive agreement under which Biogen has agreed to acquire HI-Bio for USD 1.15 billion upfront and up to USD 650 million in potential milestone payments. Discover which therapies are expected to grab the anti-CD38 mAb market share @ Anti-CD38 mAb Market Report Anti-CD38 mAb Market Dynamics The market for anti-CD38 mAbs has undergone significant growth and transformation in recent years, driven primarily by the increasing prevalence of multiple myeloma and the d emand for more effective treatment options. The market dynamics are further influenced by ongoing research into the broader application of anti-CD38 mAbs beyond multiple myeloma. There is growing interest in exploring their efficacy in other CD38-expressing malignancies, such as chronic lymphocytic leukemia and certain solid tumors. Additionally, research into combination therapies, where anti-CD38 mAbs are paired with immune checkpoint inhibitors, CAR-T cells, or other novel agents, is expanding the horizon for these treatments. Such advancements are likely to further propel the market, attracting substantial investment and fueling innovation. However, challenges such as biosimilar competition, pricing pressures, and the need for differentiation in a crowded market pose potential hurdles. The entrance of biosimilars could reduce costs but also threaten market share for existing products. Companies must navigate these challenges through strategic pricing, market access strategies, and continuous innovation to maintain their competitive edge. The anti-CD38 mAb market is poised for continued expansion, with a promising pipeline of new therapies and combinations on the horizon, making it a dynamic and evolving sector within oncology. Anti-CD38 mAb Treatment Market Monoclonal antibodies targeting CD38 are crucial in the treatment of newly diagnosed and refractory multiple myeloma. Currently, DARZALEX and SARCLISA are the two approved anti-CD38 therapies. SARCLISA is a prescription medication used to treat multiple myeloma in adults. It is administered alongside pomalidomide and dexamethasone for patients who have undergone at least two previous treatments, including lenalidomide and a proteasome inhibitor. Additionally, SARCLISA is used with carfilzomib and dexamethasone for patients who have received one to three prior therapies that were either ineffective or have stopped working. In March 2020, the US FDA approved SARCLISA in combination with pomalidomide and dexamethasone for multiple myeloma patients who had at least two prior therapies, including lenalidomide and a proteasome inhibitor. Later, in May 2020, the European Commission approved SARCLISA. By March 2021, the US FDA also approved SARCLISA with carfilzomib and dexamethasone for those with relapsed or refractory multiple myeloma who had received one to three previous treatments. DARZALEX is an innovative monoclonal antibody that the US FDA approved for treating multiple myeloma in patients with at least one prior treatment. It works by inducing tumor cell death through several mechanisms, including antibody-dependent cell-mediated cytotoxicity, complement-dependent cytotoxicity, and antibody-dependent cellular phagocytosis. In November 2015, the FDA granted DARZALEX accelerated approval as a monotherapy for multiple myeloma patients who had undergone at least three prior treatments. By November 2016, it was also approved for use in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for patients who had received at least one prior therapy. From 2015 to 2021, DARZALEX gained further approvals for use in various drug combinations. Their effectiveness in managing multiple myeloma and plasma cell disorders has been confirmed by numerous Phase III clinical trials. Moreover, CD38-targeted therapies are being explored for other conditions such as primary immune thrombocytopenia, IgA nephropathy, antibody-mediated transplant rejection, lupus nephritis, and various hematologic cancers. Learn more about the FDA-approved anti-CD38 mAb @ Anti-CD38 mAb Drugs Key Emerging Anti-CD38 mAb and Companies Several key players, including Takeda Pharmaceuticals, HI-Bio, CASI Pharmaceuticals, and others, are involved in developing drugs for Anti-CD38 mAb for various indications such as multiple myeloma, myasthenia gravis, and others. Mezagitamab is a fully human IgG1 monoclonal antibody that targets CD38 and is being developed by Takeda for the treatment of multiple myeloma, myasthenia gravis, and primary immune thrombocytopenia. On March 14, 2024, the FDA granted Fast Track designation and Orphan Drug status to mezagitamab for idiopathic thrombocytopenic purpura (ITP). Takeda also revealed plans to begin a global Phase III trial for mezagitamab in ITP later in 2024. The drug is currently in Phase II of clinical development. HI-Bio's leading candidate, felzartamab, is a fully human anti-CD38 monoclonal antibody. Clinical studies have demonstrated its ability to selectively target and deplete CD38+ cells, including plasma cells and NK cells, potentially enabling broader therapeutic applications and enhanced clinical outcomes across various immune-mediated diseases. Felzartamab has been granted Breakthrough Therapy and Orphan Drug Designations by the FDA for primary membranous nephropathy and also received Orphan Drug Designation for treating antibody-mediated kidney transplant recipients. Phase II trials have been completed for primary membranous nephropathy and antibody-mediated transplant rejection, with ongoing studies in IgA nephropathy. HI-Bio intends to progress each of these indications to Phase III. The anticipated launch of these emerging therapies are poised to transform the anti-CD38 mAb market landscape in the coming years. As these cutting-edge therapies continue to mature and gain regulatory approval, they are expected to reshape the anti-CD38 mAb market landscape, offering new standards of care and unlocking opportunities for medical innovation and economic growth. To know more about anti-CD38 mAb clinical trials, visit @ Anti-CD38 mAb Treatment Drugs Anti-CD38 mAb Overview Anti-CD38 monoclonal antibodies (mAbs) are a class of therapeutic agents that target CD38, a surface protein widely expressed on plasma cells, including malignant ones in multiple myeloma. By binding to CD38, these mAbs can induce direct cytotoxicity, promote antibody-dependent cellular cytotoxicity (ADCC), and facilitate complement-dependent cytotoxicity (CDC) to destroy the targeted cells. Beyond their role in multiple myeloma, anti-CD38 mAbs are being explored for their potential in treating other hematologic malignancies and autoimmune diseases. CD38 is not only a marker for plasma cells but also involved in processes like calcium signaling and NAD+ metabolism, which are crucial for cell survival and proliferation. By targeting CD38, these antibodies can modulate the immune microenvironment, making them a promising tool for both oncology and immunology. The ongoing research is focused on optimizing their efficacy, managing resistance, and exploring their use in combination with other immunotherapies to enhance patient outcomes. Anti-CD38 mAb Epidemiology Segmentation Epidemiology assessed for multiple myeloma showed that the United States, in 2023, accounted for 36,800 incident cases of multiple myeloma.
