Brief summary
The goal of this research study is to test if ciltacabtagene autoleucel (cilta-cel) is safe and effective in treating participants with high-risk, smoldering myeloma. The names of the treatment interventions used in this study are: * Cilta-cel (or chimeric antigen receptor T cells) * Cyclophosphamide (a lymphodepleting chemotherapy) * Fludarabine (a lymphodepleting chemotherapy)
Detailed description
This is a Phase II study to test the safety and effectiveness of study therapy cilta-cel in treating participants with high-risk smoldering multiple myeloma (SMM). T cells are a part of a person's immune system which usually helps fight infection and prevents/fights cancer cells. The U.S. Food and Drug Administration (FDA) has approved cilta-cel as a treatment for relapsed and refractory multiple myeloma but not specifically for smoldering myeloma. The research study procedures include screening for eligibility, study treatment including evaluations, blood collections, radiologic scans of tumors, bone marrow biopsies, and follow-up visits. Participation in this study is expected to last about 15 years. It is expected that about 20 people will take part in this research study. This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational therapy to learn whether the therapy works in treating a specific disease. "Investigational" means that the therapy is being studied. Janssen Research & Development, LLC is supporting this research study by providing the study treatment and funding.
Interventions
Genetically modified autologous T-cell immunotherapy, via intravenous infusion per protocol.

Examples of highly effective contraceptives include: * user-independent methods: 1) implantable progestogen-only hormone contraception associated with inhibition of ovulation; 2) intrauterine device; intrauterine hormone- releasing system; 3) vasectomized partner. * user-dependent methods: 1) combined (estrogen- and progestogen-containing) hormonal contraception associated with inhibition of ovulation: oral or intravaginal or transdermal; 2) progestogen-only hormone contraception associated with inhibition of ovulation (oral or injectable). * In addition to the highly effective method of contraception, a man: * Who is sexually active with a woman of childbearing potential must agree to use a barrier method of contraception (eg, condom with spermicidal foam/gel/film/cream/suppository) from the time of signing the ICF until 1 year after receiving a cilta-cel infusion. * Who is sexually active with a woman who is pregnant must use a condom. Women and men must agree not to donate eggs (ova, oocytes) or sperm, respectively, during the study and for 1 year after the last dose of study treatment. Note: Hormonal contraception may be susceptible to interaction with the study treatment, which may reduce the efficacy of the contraceptive method.
