Bispecific antibodies and dual-targeting CAR-T cells for multiple myeloma: latest updates from the 2023 ASCO annual meeting.

ABSTRACT: Bispecific antibodies (BsAbs) and dual-targeted chimeric antigen receptor T (CAR T) cells have been employed in relapsed/refractory multiple myeloma (RRMM) patients over the past few years, as an increasing number of patients were ineffectively treated by ≥ 3 prior lines of therapy. BCMA/CD3 and GPRC5D/CD3 are the most popular combinations. Clinical findings indicated that patients exhibit a greater susceptibility to stronger and more enduring responses. Here, we summarize the latest data from the 2023 ASCO annual meeting on BsAbs targeting BCMA/CD3, GPRC5D/CD3 and BCMA/CD19 CAR T cells.

CD20 × CD3 bispecific antibodies for lymphoma therapy: latest updates from ASCO 2023 annual meeting.

Project description:Multiple bispecific antibodies (bsAbs) have been approved for cancer immunotherapy. Several CD20 × CD3 bsAbs have demonstrated significant anti-B-cell non-Hodgkin lymphoma (NHL) activity by engaging T cells to target CD20+ NHL cells in clinical trials. Mosunetuzumab, epcoritamab and glofitamab have been approved recently for B-cell NHL therapy. In this study, we summarized several latest reports on CD20 × CD3 bsAbs for the therapy of B-cell NHL from the ASCO 2023 annual meeting (ASCO2023).

Bispecific antibodies targeting BCMA, GPRC5D, and FcRH5 for multiple myeloma therapy: latest updates from ASCO 2023 Annual Meeting.

Project description:Several bispecific antibodies (bsAbs) targeting BCMA, GPRC5D, and FcRH5 are in clinical trials for heavily pretreated multiple myeloma (MM) patients. Teclistamab was approved for relapsed/refractory MM therapy in 2022, while elranatamab, linvoseltamab, F182112, talquetamab, and cevostamab are currently undergoing clinical trials. This study summarizes several latest reports on bsAbs for the treatment of MM from the ASCO 2023 Annual Meeting.

BCMA-targeted CAR-T cell therapies in relapsed and/or refractory multiple myeloma: latest updates from 2023 ASCO Annual Meeting.

Project description:Treatment of relapsed and/or refractory multiple myeloma (RRMM) utilizing the novel therapeutic target of the B-cell maturation antigen (BCMA) has demonstrated incredible results, leading to regulatory approval of BCMA-targeted chimeric antigen receptor (CAR)-T cell therapies in RRMM. With now two approved BCMA-targeted CAR-T cell therapies, investigators globally are working to build off and improve upon BCMA-targeted therapies. We discuss long-term data from the pivotal study that led to CAR-T approval, a phase 3 trial supporting their use in earlier lines, and novel manufacturing platforms to decrease vein-to-vein time. We highlight five key abstracts from the 2023 ASCO Annual Meeting that showcase these exciting updates in BCMA-directed CAR-T cell therapies in RRMM.

Bispecific antibody treatment of multiple myeloma: latest updates from the 2022 ASH annual meeting.

Project description:BackgroundEffective novel therapies for multiple myeloma (MM) patients who are unresponsive to conventional treatments (triple-class refractory) are an urgent need. Bispecific antibodies (BsAbs) offer a promising new approach to stimulate T cells and induce tumor cell death by targeting molecules on the surface of malignant plasma cells and CD3 on the surface of T cells.ObjectivesAddressing the issue of improving the prognosis of triple-class refractory MM patients has become a significant clinical challenge.DesignThis is a brief report.MethodsThis article summarizes the latest updates of BsAbs treatment of MM from the 2022 ASH annual meeting.ResultsBsAbs that target B-cell maturation antigen and G protein-coupled receptor family C group 5 memberD have demonstrated remarkable clinical activity and favorable safety profiles. Many potential targets for myeloma cells are currently undergoing phase I/II clinical trials, and these off-the-shelf bispecific molecules are likely to become a critical part of the MM treatment landscape.ConclusionThis article provides an overview of the latest advances in BsAbs immunotherapy for refractory and relapsed MM and highlights significant findings from the 2022 ASH annual meeting.

Dual-targeted CAR T-cell immunotherapies for hematological malignancies: latest updates from the 2023 ASH annual meeting.

Project description:Over the past few years, dual-targeted chimeric antigen receptor (CAR) T-cell therapy has been employed in the management of hematological malignancies to mitigate treatment failure, particularly in cases of antigen escape. The most widely used approaches include CD19/CD20, CD20/CD22, and BCMA/CD19 CAR T-cells. Alternative immune cells, including natural killer T cells and invariant natural killer T cells, exhibit innate anti-tumor activity and reduced toxicity. This review summarizes several recent clinical trial reports and preclinical studies from the 2023 American Society of Hematology (ASH) annual meeting on dual-targeted CAR T-cell immunotherapy for hematological malignancies.

Targeted protein degradation in hematologic malignancies: latest updates from the 2023 ASH annual meeting.

Project description:Protein degraders, emerging as a novel class of therapeutic agents, have gained widespread attention due to their advantages. They have several advantages over traditional small molecule inhibitors, including high target selectivity and ability to target "undruggable" targets and overcome inhibitor drug resistance. Tremendous research and development efforts and massive investment have resulted in rapid advancement of protein degrader drug discovery in recent years. Here, we overview the latest clinical and preclinical updates on protein degraders presented at the 2023 ASH Annual Meeting.

Immunotherapies targeting GPRC5D in relapsed or refractory multiple myeloma: latest updates from 2022 ASH Annual Meeting.

Project description:B cell maturation antigen (BCMA)-targeted immunotherapy has shown unprecedented results in the treatment of relapsed or refractory (R/R) multiple myeloma (MM). However, disease progression remains an issue attributed to variable BCMA expression, BCMA downregulation, and heterogeneity of tumor antigens in MM. Therefore, additional treatment options with novel therapeutic targets are warranted. G protein-coupled receptor, class C group 5 member D (GPRC5D), an orphan receptor expressed on malignant plasma cells with limited expression in normal tissue, has emerged as a promising therapeutic target for R/R MM. GPRC5D-targeted chimeric antigen receptor (CAR)-T and CAR-NK cell therapy, as well as bispecific T cell engagers, offer remarkable anti-tumor activities. We summarized some latest reports on GPRC5D-targeted treatments for R/R MM from the 2022 ASH Annual Meeting (ASH 2022).

CAR T cell therapy for T cell leukemia and lymphoma: latest updates from 2022 ASH Annual Meeting.

Project description:Due to the concern of fratricide, clinical development of CAR T cells for the therapy of T cell malignancies lags behind that for B cell malignancies. Attempts are being made to revise T cell biomarkers so that the re-engineered CAR T cells can target T cell malignancies. CD3 and CD7 are the two pan-T cell surface biomarkers that have been either knocked out or knocked down through genome base- editing technology or by protein expression blockers so that the re-engineered T cells can target T cells without fratricide. We summarized several latest reports on the CAR T cells for the therapy of T cell leukemia /lymphoma from the 2022 ASH Annual Meeting, with latest updates on clinical trials of TvT CAR7, RD-13-01, and CD7 CART.

Bispecific antibodies as monotherapy or in combinations for non-hodgkin B-cell lymphoma: latest updates from the American society of hematology 2022 annual meeting.

Project description:Recent evidence suggests that bispecific antibodies (BsAbs) exhibit promising efficacy and low toxicity even in heavily treated non-Hodgkin B-cell lymphoma (B-NHL). However, the role of BsAbs in previously untreated NHL and the efficacy and safety of BsAbs used in combination remain uncertain. We summarized data published at the 64th American Society of Hematology (ASH) Annual Meeting on BsAb monotherapy or combination therapy for first-line or relapsed/refractory B-NHL. BsAb monotherapy in elderly/unfit newly diagnosed (ND) DLBCL patients achieved ORR and CR rates of 56% and 43%, respectively. In addition, BsAbs combined with chemotherapy or other novel agents raised the ORR higher than 50% without increasing the incidence of grade ≥ 3 CRS. We conclude that BsAb monotherapy or combination therapy for first-line or relapsed/refractory B-NHL has high efficacy and satisfactory safety.
