简要总结
The purpose of this study is to examine the safety, efficacy and feasibility of the use of one standard dose of siltuximab prior to teclistamab infusion. Siltuximab is an investigational (experimental) drug that works by binding directly to human interleukin-6 (IL-6). IL-6 is a cytokine; these are products that are secreted by certain cells of the immune system and effect other cells in participant's body. IL-6 regulates immune, inflammatory and metabolic processes. Siltuximab has already been tested and approved for use by the FDA in participants with a condition called multicentric Castleman's disease, which is a lymphoproliferative disorder. This study is being conducted to investigate if administration of a single dose of siltuximab will reduce the rates of and severity of Cytokine Release Syndrome (CRS) and Immune effector Cell-Associated Neurotoxicity Syndrome (ICANS) in participants prior to teclistamab administration. CRS and ICANS are adverse effects commonly experienced by participants being treated with teclistamab that are related to inflammation in the body. Siltuximab is experimental because it is not approved by the Food and Drug Administration (FDA) for prophylactic use prior to administration of teclistamab infusion.
详细描述
Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity (ICANS) are clinically relevant toxicities of bsAbs and other T cell redirecting therapies. The armamentarium of immunotherapeutic approaches is expected to grow at exponential rates in the upcoming years, with an expansion of the diseases treated with this modality.
While the risk of CRS and ICANS is limited with most bsAbs(bispecific antibodies), these side effects can prevent a more widespread adoption of these therapies and impede their use in participants for whom access to tertiary or quaternary medical centers is limited.
The development of strategies that prevent CRS and ICANS occurring after bispecific antibodies can increase the prescription of these effective immunotherapies, in particular for participants for whom access to care is limited.
Siltuximab is a chimeric murine antibody that binds directly to IL-6 and has been used effectively in the treatment of CRS, with guidelines recommending its use in CRS cases refractory to tocilizumab.
Study hypothesis is that, through direct binding of IL-6, siltuximab can overcome the risk of increased IL-6 - mediated ICANS by decreasing the available IL-6 for blood brain barrier passage and by facilitating clearance of IL-6 through IL-6 receptor-mediated mechanisms.

入选标准
- •Adults 18 years of age and older.
- •Relapsed or refractory measurable multiple myeloma following prior treatment with ≥4 lines of anti-myeloma therapy slated for teclistamab monotherapy
- •Adequate bone marrow function including:
- •Hemoglobin ≥ 8g/dL (unless ≥50% bone marrow involvement by MM),
- •Absolute neutrophil count >1000 / µL (unless bone marrow involvement by MM)
- •Platelet count ≥30,000 / µL (unless bone marrow involvement by MM)
- •ECOG performance status 0 - 2
- •For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of < 1% per year during the treatment period and for 3 months after the last dose of siltuximab.
- •A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (< 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus).
- •Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
- •The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
- •For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
- •With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period. Men must refrain from donating sperm during this same period.
- •With pregnant female partners, men must remain abstinent or use a condom during the treatment period.
- •The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
排除标准
- •Waldenström's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes), or AL amyloidosis.
- •Known to be seropositive for human immunodeficiency virus or acquired immune deficiency syndrome.
- •Hepatitis B infection as defined according to the American Society of Clinical Oncology guidelines. In the event the infection status is unclear, quantitative levels are necessary to determine the infection status (Attachment 10). Hepatitis C (anti-hepatitis C virus [HCV] antibody positive or HCV-RNA quantitation positive) or known to have a history of hepatitis C. If positive, further testing of quantitative levels to rule out positivity is required.
- •Active central nervous system or meningeal involvement by MM.
- •Active bacterial, viral, fungal, mycobacterial, parasitic or other infection requiring systemic therapy within 2 weeks prior to first dose of study drug.
- •Active malignancy except for any of the following:
- •Adequately treated cutaneous basal cell carcinoma, squamous cell carcinoma, or in situ cervical cancer
- •Adequately treated Stage I cancer from which the subject is currently in remission and has been in remission for 2 years
- •Low-risk prostate cancer with Gleason score <7, prostate-specific antigen <10 ng/mL, and a stage of cancer at most cT2a, cN0, and CM0
- •Any other cancer from which the subject has been disease-free for ≥2 years
- •Participants with uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, pulmonary abnormalities or psychiatric illness/social situations that would limit compliance with study requirements.
- •Pregnant or breastfeeding women are excluded from this study because siltuximab therapy may be associated with the potential for teratogenic or abortifacient effects. Women of childbearing potential must have a negative serum pregnancy test. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with siltuximab, breastfeeding should be discontinued during treatment and for 3 months after the last dose of siltuximab. These potential risks may also apply to other agents used in this study.
- •Participants with history of clinically relevant and active CNS pathology such as epilepsy, seizure disorders, paresis, aphasia, uncontrolled cerebrovascular disease, severe brain injuries, dementia and Parkinson's disease.
- •Participants with history of severe hypersensitivity reaction to siltuximab or any of the excipients
研究组 & 干预措施

Participants will receive a single dose of prophylactic siltuximab, 11 mg/kg, 2 hours prior to the administration of the first dose of teclistamab on day 1. There is no planned dose escalation of siltuximab, and teclistamab dosing will be done following the standard planned ramp-up mentioned below. Participants will be hospitalized for 9 days according to teclistamab package insert and Cleveland Clinic institutional practice. Participants will be followed for the incidence of CRS and ICANS for the first two 22-day cycles of treatment.
