A Phase 1b/2 Study of Talquetamab Plus Concomitant Priming Radiotherapy in Multiple Myeloma With Extramedullary Disease

This phase I/II trial tests the safety and effectiveness of extramedullary disease (EMD)-directed external beam radiation therapy (EBRT) in combination with talquetamab for the treatment of multiple myeloma patients with extramedullary disease. Extramedullary disease in multiple myeloma involves the infiltration of organs and soft tissues by malignant plasma cells and has proven difficult to treat. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink cancers. EBRT is a type of radiation therapy that delivers high-energy beams to the cancer from outside of the body. In this trial, the EBRT will be directed to a site of extramedullary disease. Talquetamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Combining EMD-directed EBRT with talquetamab may be safe, tolerable, and/or effective in treating multiple myeloma patients with extramedullary disease.

Real-world experience with clinical management of talquetamab in relapsed/refractory multiple myeloma: a qualitative study of US healthcare providers

Article

作者: DeBrosse, Amalia ; Hawks, Kelly ; Schinke, Carolina ; Mazzoni, Sandra ; Dhakal, Binod ; Okorozo, Peter ; Le, Hoa H. ; Patel, Saurabh ; Richards, Tiffany ; McDowell, Rachel ; Zhang, Xinke ; Rodriguez, Cesar ; Bunn, Jonathan ; Scott, Sara A. ; Shenoy, Samantha

OBJECTIVETalquetamab is the first-in-class GPRC5DxCD3 bispecific antibody for relapsed/refractory multiple myeloma. Given limited real-world data, this study was conducted with US healthcare providers (HCPs) to understand real-world talquetamab dosing and symptom management.METHODSIn February/March 2024, individual in-depth interviews (IDIs; n = 10) were conducted with HCPs administering talquetamab in real-world settings. A subsequent expert panel (n = 6) further discussed current practices.RESULTSThe IDIs reported a variety of settings for step-up dosing (SUD), including inpatient (n = 5), outpatient (n = 3), and hybrid models (n = 2), with a trend toward shorter SUD length to reduce healthcare resource utilization. Most HCPs used a biweekly (Q2W) schedule in SUD (n = 7) and treatment phases (n = 8). Six participants explored reducing dose frequency to every 4 weeks (Q4W) in patients following positive disease response to treatment, considering patient convenience and relieving GPRC5D-related symptoms. Panelists recommended symptom management and prophylactic strategies, such as dexamethasone and nystatin mouthwash or zinc and vitamin B complex for oral symptoms, and topical steroids and cosmetic products for skin and nail symptoms.CONCLUSIONThis study outlines current real-world practices for talquetamab. Findings indicate variation in the SUD care setting. The 0.8 mg/kg Q2W dosing schedule was most common, although switching to Q4W is a real-world symptom management strategy for some patients with responses to therapy. GPRC5D-related symptom management approaches are evolving; prophylactic use of dexamethasone and nystatin mouthwash or zinc and vitamin B complex may be effective strategies to alleviate oral symptoms. Further real-world evidence is needed to inform optimal dosing schedules while mitigating symptom impact.

Matching-adjusted indirect comparison of talquetamab vs selinexor-dexamethasone and vs belantamab mafodotin in patients with relapsed/refractory multiple myeloma

Article

OBJECTIVETalquetamab is the first GPRC5D-targeting bispecific antibody approved for the treatment of triple-class exposed (TCE) relapsed/refractory multiple myeloma (RRMM). This matching-adjusted indirect comparison (MAIC) study was conducted to compare the effectiveness of talquetamab vs selinexor-dexamethasone (sel-dex) and vs belantamab mafodotin (belamaf) in patients with TCE RRMM.METHODSAn unanchored MAIC was performed using individual patient-level data from patients treated with subcutaneous talquetamab 0.4 mg/kg weekly (QW) and 0.8 mg/kg every other week (Q2W) from MonumenTAL-1 (NCT03399799/NCT04636552) and published summary data for sel-dex from STORM (NCT02336815) and belamaf from DREAMM-2 (NCT0325678). Patients from MonumenTAL-1 who met key eligibility criteria for STORM and DREAMM-2 were included. Outcomes of interest were overall response rate (ORR), complete response or better (≥CR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS).RESULTSAfter adjustment for cross-trial differences, patients treated with both dosing schedules of talquetamab showed significantly better ORR, ≥CR, and DOR vs sel-dex and significantly higher ORR and ≥ CR vs belamaf; DOR was relatively similar to belamaf. PFS was significantly improved with talquetamab Q2W and numerically in favor of talquetamab QW vs sel-dex and significantly improved with both dosing schedules of talquetamab vs belamaf. OS was significantly improved with both dosing schedules of talquetamab vs sel-dex and was numerically in favor of both dosing schedules of talquetamab vs belamaf.CONCLUSIONThese analyses show superior effectiveness of both talquetamab dosing schedules vs sel-dex and vs belamaf for most outcomes and highlight talquetamab as an effective treatment option for patients with TCE RRMM.

Clinical Management of Patients With Relapsed/Refractory Multiple Myeloma Treated With Talquetamab

BACKGROUNDTalquetamab is a bispecific antibody targeting the multiple myeloma-associated antigen G protein-coupled receptor family C group 5 member D (GPRC5D). In the phase 1/2 MonumenTAL-1 trial (NCT03399799/NCT04634552), overall responses rates were > 71% in patients with triple-class exposed relapsed/refractory multiple myeloma (RRMM). Due to the distribution of the target antigen, a unique pattern of GPRC5D-associated adverse events (AEs) was observed, together with T-cell redirection-associated AEs. Management strategies for talquetamab-associated AEs are described.DISCUSSIONGPRC5D-associated AEs included dermatologic (rash, nonrash, and nail toxicities) and oral AEs (dysgeusia, dysphagia, and dry mouth). The incidence of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were consistent with other T-cell redirection therapies. The incidence of high-grade infections was lower than observed with B-cell maturation antigen-targeting bispecific antibodies, with less frequent use of intravenous immunoglobulin required. GPRC5D-associated AEs were mostly low grade and led to few discontinuations. Skin toxicities were managed with emollients, topical corticosteroids, and oral corticosteroids (for high-grade, persistent, or AEs that progress). Nail toxicities were commonly managed with emollients. Based on investigator experience, dose modification may be effective for controlling oral events. Observation for potential weight changes is required. Infections were managed per standard of care. CRS and ICANS were effectively managed, consistent with other trials of T-cell redirection therapies.CONCLUSIONAlthough talquetamab had a distinct safety profile, AEs were considered clinically manageable and mostly low grade. With appropriate education and support, health care practitioners can ensure patients with RRMM maintain quality of life and treatment adherence. VIDEO ABSTRACT.
