Brief Summary
The purpose of this study is to find out whether giving a single dose of tocilizumab before treatment with ramantamig can help prevent or reduce the severity of cytokine release syndrome (CRS) within 28 days from ramantamig, compared to participants who receive placebo. CRS is an acute inflammatory reaction that can occur during treatment and may be associated with flu-like or other systemic symptoms, such as fever and tiredness.

By the end of Day 28 from first ramantamig dose
Percentage of Participants with Treatment-Emergent CRS of any ASTCT Grade, Grade >=2, and Grade >=3 During Ramantamig Treatment
Up to 38 months
Percentage of Participants with Re-occurrence of CRS with ASTCT Grade >=2 After the Initial Occurrence of Treatment-Emergent Grade >=2 CRS Event
Up to 38 months
Percentage of Participants with Re-occurrence of CRS for All Grades
Up to 38 months

Study Arms (2)
Arm A: Tocilizumab + Ramantamig
EXPERIMENTALParticipants will receive tocilizumab along with ramantamig. Ramantamig will be administered for a total treatment of finite duration, or until progressive disease (PD) or intolerable toxicity (whichever is earlier).
Arm B: Placebo + Ramantamig
PLACEBO COMPARATORParticipants will receive placebo (saline) along with ramantamig. Ramantamig will be administered for a total treatment of finite duration, or until PD or intolerable toxicity (whichever is earlier).
Interventions
Ramantamig will be administered as subcutaneous (SC) injection.
Tocilizumab will be administered as intravenous (IV) injection.
Eligibility Criteria
You may qualify if:
- Documented diagnosis of multiple myeloma (MM) as defined by the criteria: a. MM diagnosis according to the international myeloma working group (IMWG) diagnostic criteria; b. Measurable disease at screening as assessed by local laboratory as defined in the protocol
- Received at least 1 prior lines of antimyeloma therapy
- Relapsed or refractory disease as defined: a. Relapsed disease is defined as an initial response to prior treatment, followed by confirmed progressive disease (PD) by the IMWG response criteria greater than (\>) 60 days after cessation of treatment.; b. Refractory disease is defined as failure to achieve a response or confirmed PD by the IMWG response criteria during previous treatment or less than or equal to (\<=) 60 days after cessation of treatment
- Have an eastern cooperative oncology group (ECOG) performance status (PS) score of 0 to 2 at screening and immediately before the start of study treatment administration. Participants with ECOG PS 2 or 3 are eligible for the study if the ECOG PS score is related to stable physical limitations (example, wheelchair-bound due to prior spinal cord injury) and not related to MM or associated therapy
- Have clinical laboratory values meeting the criteria specified in the protocol
You may not qualify if:
- Concurrent use of any other anticancer treatment (including non-palliative radiotherapy) or investigational agent
- Major surgery, (for example, requiring general anesthesia) within 2 weeks before first dose, or will not have fully recovered from surgery, or has surgery planned during the time the participant is expected to participate in the study
- Suspected or known allergies, hypersensitivity, or intolerance to ramantamig and tocilizumab or their excipients
- Presence of any of the following: a. Any ongoing myelodysplastic syndrome or B-cell malignancy (other than MM); b. Any history of malignancy, other than MM, that is considered at high risk of recurrence requiring systemic therapy; c. Any active malignancy other than MM
- Known active or prior central nervous system (CNS) involvement or exhibits clinical signs of meningeal involvement of MM. If either is suspected, negative whole brain magnetic resonance imaging (MRI) and lumbar cytology are required
