A Study Evaluating the Prophylactic Use of Tocilizumab to Prevent Cytokine Release Syndrome With Ramantamig Administration in Participants With Relapsed/Refractory Multiple Myeloma
(TRI Pro)
What this study is about
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.
View original scientific description
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.
Interventions
DRUG
Ramantamig
Ramantamig will be administered as subcutaneous (SC) injection.
DRUG
Tocilizumab
Tocilizumab will be administered as intravenous (IV) injection.
DRUG
Placebo
Placebo (saline) will be administered as IV injection.
Primary outcome measures
Percentage of Participants Alive and Free of Treatment-Emergent American Society for Transplantation and Cellular Therapy (ASTCT) Grade Greater Than or Equal to (>=) 2 Cytokine Release Syndrome (CRS)
Time frame: End of Day 28 from ramantamig dose
Percentage of participants alive and free of treatment-emergent ASTCT Grade \>=2 CRS without the use of intervening treatment for CRS of any grade by the end of Day 28 from ramantamig dose will be reported.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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 (that is, partial response or better) 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 during the screening and within 1 day of the start of administration of study treatment
Exclusion criteria
- 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 that is considered at high risk of recurrence requiring systemic therapy
- 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
