Median number of prior lines was 4 (range 1-13), 19.4% had received CAR-T previously, and 12.9% had been previously exposed to another TCE.Twenty-three pts (74.2%) were enrolled in clinical trials (7 with teclistamab, Tec, 6 with talquetamab, Tal, and 10 with investigational agents). Twelve of these pts received TCE in combination with daratumumab and/or pomalidomide...MRD- seems to translate into long PFS, regardless of HR disease. Prospective studies on fixed duration treatment with TCE based on baseline risk and treatment response are needed.

Currently, two BCMA-targeting BsAbs (teclistamab and elranatamab) and one GPRC5D-targeting BsAb (talquetamab) have regulatory approval for the treatment of patients (pts) with RRMM. Conclusions : CMMC counts through serial peripheral blood sampling can be used to assess disease burden and early kinetics of response to BsAb therapy. Further follow-up and additional cohorts are planned to confirm performance of this assay as a biomarker in predicting response and long-term outcomes in patients receiving BsAb and other therapies, as well as interrogating mechanisms of resistance through targeted sequencing and analysis of tumor-associated antigens of enumerated cells.

Conclusions : Tal-DP exhibits a deep, long-term impact on efficacy through complementary mechanisms of action and may be especially beneficial in pts with prior BsAb exposure, who typically have unfavorable BL immune profiles. Ongoing analyses of tec-DP from MajesTEC-2 (NCT04722146) will be presented.

Forimtamig is currently being evaluated in Phase 1 clinical trials in relapsed and refractory myeloma (RRMM) patients for monotherapy and in combination treatments. NCT04557150.

These modeling results suggest that IL-6 release due to talquetamab-induced cytokine release syndrome has limited impact on potential drug-drug interactions, with the highest likelihood of impact occurring from initiation of talquetamab step-up dosing up to 7 (QW) or 9 (Q2W) days after first treatment dose in cycle 1 and during and after cytokine release syndrome. Multiple myeloma can be treated with immunotherapies such as the bispecific antibody, talquetamab, which binds the novel antigen G protein-coupled receptor family C group 5 member D on multiple myeloma cells and CD3 on T cells and induces T-cell-mediated lysis of multiple myeloma cells. Following talquetamab treatment, many patients experience cytokine release syndrome, an inflammatory immune response where levels of proinflammatory cytokines, including interleukin (IL)-6, are increased. Interleukin-6 can suppress the activity of important enzymes in the body (cytochrome [CYP] P450s) that are involved in drug clearance. This study used a physiologically based pharmacokinetic computer model to investigate the potential impact of increased IL-6 levels on CYP450 enzymes to determine subsequent impact on drugs that are metabolized by CYP450 enzymes. The results showed no predicted interaction between median levels of IL-6 observed in patients and CYP substrates (such as caffeine and omeprazole) with talquetamab. In a simulation that assessed higher (maximum) IL-6 levels observed in patients, the predicted impact of IL-6 was minimal to weak for most of the CYP substrates assessed. The effect on CYP450 enzymatic activity was highest from initiation of talquetamab step-up dosing up to 7-9 days after the first treatment dose of talquetamab. These results suggest that, in this treatment time period, elevated IL-6 levels due to talquetamab-induced cytokine release syndrome have limited impact on drugs that are CYP substrates that may be used in conjunction with talquetamab, but that the concentration and toxicity of these drugs should be monitored and the dose of CYP substrate adjusted as required.

Oncology nurses have specialized knowledge of treatment administration monitoring based on their participation in the MonumenTAL-1 trial. This review provides information for nurses in both the academic and community settings on how to monitor, counsel, and support patients, which will in turn improve patients' quality of life and overall survival.

Primary resistance is characterized by a low T-cell/MM cell-ratio and Treg-driven immunosuppression, while reduced T-cell fitness due to continuous BsAb-mediated T-cell activation may contribute to development of acquired resistance.
