Outpatient Administration of Teclistamab or Talquetamab for Multiple Myeloma

Description

This is a phase II study to evaluate the outpatient administration of Teclistamab or Talquetamab in Multiple Myeloma patients* This is a two-arm, non-randomized, multicenter, prospective study in adult patients with RRMM, who are administered Teclistamab (TECVAYLI™) or Talquetamab (TALVEY™), in the post-marketing setting. * Teclistamab (TECVAYLI™) is a humanized IgG-4 PAA bispecific antibody designed to target the CD3 receptor complex on T cells and BCMA on B-lineage cells. * Talquetamab (TALVEY™) is a humanized IgG-4 bispecific antibody designed to target the CD3 receptor complex on T cells and GPRC5D-expressing multiple myeloma (MM) cells This study will investigate the use of prophylactic tocilizumab to reduce the incidence and severity of CRS associated with teclistamab or talquetamab administration, to enable administration of the step-up dosing regimen of teclistamab or talquetamab in an outpatient setting.

Exclusion Criteria: * Has high tumor burden, defined as having ≥60% plasma cell infiltrate on the bone marrow biopsy or aspirate, whichever is higher, or with multiple extramedullary disease sites or plasmacytomas. * Has a rapidly progressing disease per investigator assessment. * Has plasma cell leukemia (\>2.0×10\^9/L plasma cells by standard differential), Waldenström's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes), or primary amyloid light-chain amyloidosis. * Has known active CNS involvement or exhibits clinical signs of meningeal involvement of MM. * Has risk factors for developing clinically significant TLS and requiring management with increased hydration, allopurinol, or rasburicase. * Has myelodysplastic syndrome or active malignancies (ie, progressing or requiring treatment change in the last 12 months) other than RRMM. The only allowed exceptions are: * Any malignancy that was not progressing nor requiring treatment change in the last 12 months. * Malignancies treated within the last 12 months and considered at very low risk for recurrence: * Non-muscle invasive bladder cancer (solitary Ta-PUNLMP or low grade, \<3 cm, no CIS). * Skin cancer (non-melanoma or melanoma). * Noninvasive cervical cancer. * Breast cancer: adequately treated lobular carcinoma in situ or ductal carcinoma in situ, localized breast cancer and receiving antihormonal agents. * Localized prostate cancer (M0, N0) with a Gleason Score ≤7a, treated locally only (RP/RT/focal treatment). * Other malignancy that is considered at minimal risk of recurrence. * Has Grade ≥3 hematologic AEs or Grade ≥3, clinically significant non-hematologic AEs. * Has fever or active infection (bacterial, viral, or uncontrolled systemic fungal) at time of study enrollment. * Has active autoimmune disease or a documented history of autoimmune disease with the exception of vitiligo, type I diabetes, and prior autoimmune thyroiditis that is currently euthyroid based on clinical symptoms and laboratory testing. * Has clinically significant coagulopathy that would increase the risk of bleeding in the setting of cytopenia. * Shows a deterioration in neurologic status, including mental status changes such as confusion or increased somnolence. * Has psychiatric disorders (eg, alcohol or drug abuse), dementia, or altered mental status that would compromise the ability to provide informed consent or comply with the clinical protocol. * History of stroke, transient ischemic attack or seizure within 6 months of signing ICF. * Presence of the following cardiac conditions: * New York Heart Association stage III or IV congestive heart failure. * Myocardial infarction or CABG ≤6 months prior to enrollment. * History of clinically significant ventricular arrhythmia or unexplained syncope, not believed to be vasovagal in nature or due to dehydration. * History of severe non-ischemic cardiomyopathy. * Poorly controlled coronary artery disease and/or congestive heart failure. * Uncontrolled cardiac arrhythmia or clinically significant ECG abnormalities. * Has hepatitis B infection (ie, HBsAg or HBV-DNA positive).
