Dose Escalation Study of Talquetamab in Participants With Relapsed or Refractory Multiple Myeloma

An NCI or FDA source cites this study. A citation does not establish that it applies to an individual diagnosis.

Phase: PHASE1
Status at capture: ACTIVE NOT RECRUITING
Registry last update: 2026-07-07

The purpose of this study is to characterize the safety of Talquetamab and to determine the recommended Phase 2 dose(s) (RP2Ds) and dosing schedule assessed to be safe for Talquetamab (Part 1 \[Dose Escalation\]) and to further characterize the safety of Talquetamab at the recommended Phase 2 dose(s) (RP2Ds) (Part 2 \[Dose Expansion\]).

Part 2: Participants with multiple myeloma measurable by central laboratory assessment who have progressed on, or could not tolerate, all available established therapies; Serum monoclonal paraprotein (M-protein) level greater than or equal to (\>=) 1.0 gram per deciliter (g/dL) or urine M-protein level \>=200 milligram per 24 hours (mg/24 h) or light chain multiple myeloma without measurable disease in the serum or the urine: serum immunoglobulin free light chain (FLC) \>= 10 mg/dL and abnormal serum immunoglobulin kappa lambda FLC ratio; If central laboratory assessments are not available, relevant local laboratory measurements must exceed the minimum required level by at least 25% * Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1 * Women of childbearing potential must have a negative pregnancy test at screening and prior to the first dose of study drug using a highly sensitive pregnancy test either serum (Beta human chorionic gonadotropin \[beta-hCG\]) or urine * Sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study, and is willing to and able participate in the study. Consent is to be obtained prior to the initiation of any study-related tests or procedures that are not part of standard-of-care for the participant's disease Exclusion Criteria: * Participants who received or plan to receive any live, attenuated vaccine within 4 weeks prior to the first dose, during treatment, or within 4 weeks of the last dose of Talquetamab. Non-live or non-replicating vaccines approved or authorized for emergency use (example, coronavirus disease \[COVID\]-19) by local health authorities are allowed * Toxicities from previous anticancer therapies should have resolved to baseline levels or to Grade 1 or less except for alopecia or peripheral neuropathy * Received a cumulative dose of corticosteroids equivalent to greater than or equal to ( \>=) 140 milligram (mg) of prednisone within the 14-day period before the first dose of study drug (does not include pretreatment medication) * An allogenic stem cell transplant within 6 months before first dose of study drug. Participants who received an allogeneic transplant must be off all immunosuppressive medications for 6 weeks without signs of graft-versus-host disease (GVHD); and/or an autologous stem cell transplant less than or equal to (\<=) 12 weeks before first dose of study drug * Documented history of central nervous system (CNS) involvement or exhibits clinical signs of meningeal involvement of multiple myeloma.

Treatment arms and interventions

arm Groups

description
Participants will receive IV infusion of Talquetamab at minimum anticipated biologic effect level (MABEL)-based starting dose until the completion of the end of treatment visit. Subsequent dose levels will be selected based on the review of all available data including, but not limited to, pharmacokinetic, pharmacodynamic, safety, and preliminary antitumor activity data. Participants receiving IV dosing can transition to SC dosing through-out the study upon sponsor consultation. All participants (ongoing and those who are in follow-up) will transition to open-label extension (OLE) phase and will continue to receive the study treatment. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the long-term extension (LTE) and will continue to receive study treatment.
