Cevostamab in Patients with Heavily Pretreated Relapsed/Refractory Multiple Myeloma (RRMM): Updated Results from an Ongoing Phase I Study Demonstrate Clinically Meaningful Activity and Manageable Safety and Inform the Doses and Regimen for Combination Studies (ASH 2024)
Pts with CRS were managed with tocilizumab (47.4%), steroids (21.1%), or both agents (10.5%). Cevostamab demonstrates clinically meaningful activity and manageable safety at the 160mg TD level in pts with heavily pretreated RRMM. C1 TS dosing provides effective CRS mitigation. Cevostamab combination studies may use the 0.3/1.2/3.6mg TS regimen and the Q3W 160mg TD (or similar TD exposure).

IL-15/IL-15Rα-Fc fusion protein XmAb24306 potentiates activity of CD3 bispecific antibodies through enhancing T cell expansion. (PubMed, Mol Cancer Ther)
Activation of human peripheral T cells by cevostamab, an anti-FcRH5/CD3 TDB, or anti-HER2/CD3 TDB resulted in upregulation of IL-2/15Rβ (CD122) receptor subunit in nearly all CD8+ and majority of CD4+ T cells, suggesting that TDB treatment may sensitize T cells to the IL-15. In summary, our results support the hypothesis where the number of tumor infiltrating T cells is rate limiting for the activity of solid tumor targeting TDBs. Upregulation of CD122 by TDB treatment and the observed synergy with XmAb24306 and T cell bispecific antibodies supports clinical evaluation of this novel immunotherapy combination.

Evaluation of Immune Reconstitution in Patients with Relapsed/Refractory Multiple Myeloma (RRMM) Treated with Cevostamab in Phase I Study GO39775 (ASH 2023)
At data cut-off (March 1, 2023), a total of 310 patients were enrolled in GO39775. 76 patients met the inclusion criteria and were eligible for analysis. Median age was 65 years (range: 43–82), with a median of 6 previous lines of therapy (range: 2–12).

High Dimensional Profiling of Patient-Derived Multiple Myeloma Bone Marrow Specimens Treated with an FcRH5-Targeted Bispecific Ex Vivo (ASH 2023)
Background: Cevostamab is an FcRH5 (Fc receptor-homolog 5) targeted T cell-dependent bispecific (TDB) currently being evaluated in the clinic, with promising activity and favorable safety profile as a monotherapy in patients (pts) with heavily pre-treated Relapsed/Refractory multiple myeloma (MM) (NCT03275103, Trudel et al... We first examined the T cell compartment by scRNA-seq profiling. Upon FcRH5 TDB treatment, clustering analysis suggested that CD4 and CD8 T cells undergo extensive transcriptional changes compared to control TDB (Fig 1A). A TNF and LTA-expressing CD4 memory cluster was enriched upon treatment in both SoRs and Rs, but to a greater extent in Rs.

Sequential T-Cell Engagement for Myeloma ("STEM") Trial: A Phase 2 Study of Cevostamab Consolidation Following BCMA CAR T Cell Therapy (ASH 2023)
Background and significance: The BCMA-targeted CAR T products idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel) are currently approved for relapsed/refractory multiple myeloma (RRMM) patients with ≥4 prior lines of therapy, including an IMID, proteasome inhibitor, and CD38 antibody. This phase 2 study is exploring the efficacy, safety, and feasibility of cevostamab consolidation following BCMA-directed CAR T cell therapy for RRMM, with the goal of sequential T cell engagement against 2 different antigens to eliminate residual disease. Accrual started in July 2023.

Integrative Analysis of the Tumor and Microenvironment to Model the Molecular Heterogeneity Underlying the Response to Cevostamab in Relapsed/Refractory Multiple Myeloma (ASH 2023)
Patients who had less than 25% missingness in any data layer were selected from the single-step (3.6/90–252mg dose levels [n=49] and 3.6/90mg tocilizumab premedication group [n=14; Trudel et al. Our novel, unbiased, machine learning, integrative clustering approach not only revealed unique molecular subtypes that illustrate the heterogeneity of patients with RRMM, but also identified immunological features associated with potentially reduced response to cevostamab therapy, which could provide direction for future research.

Pretreatment with Tocilizumab Prior to the CD3 Bispecific Cevostamab in Patients with Relapsed/Refractory Multiple Myeloma (RRMM) Showed a Marked Reduction in Cytokine Release Syndrome Incidence and Severity (ASH 2022)
Pts in both arms received corticosteroid, antihistamine and acetaminophen premedication prior to cevostamab. Clinical data from the GO39775 study shows for the first time that TCZ pretreatment can significantly reduce the risk of developing TDB-induced CRS without an apparent impact on anti-myeloma activity. The data support additional investigation of the use of anti-cytokine pretreatment with the goal of substantially reducing the frequency and potentially the severity of CRS.

Enduring Responses after 1-Year, Fixed-Duration Cevostamab Therapy in Patients with Relapsed/Refractory Multiple Myeloma: Early Experience from a Phase I Study (ASH 2022)
Early data from this Phase I study suggest that patients can maintain durable responses (≥6 months) after completion of 17 cycles of cevostamab treatment, highlighting the potential for an extended treatment-free period following fixed-duration therapy. Further data are needed to confirm the duration of response and associated correlates following completion of treatment. Additional data on responding patients with premature discontinuation of treatment (i.e.
