Ciltacabtagene Autoleucel in High-Risk Smoldering Multiple Myeloma

Recruiting now · Phase 2

Conditions studied: High Risk Smoldering Multiple Myeloma

In brief

This is an open-label, single arm, multicenter, interventional study with Dara-VRD followed by cilta-cel in high-risk smoldering multiple myeloma (SMM) patients. The primary objectives of this trial, related with efficafy and safety of the treatment, are i) to evaluate the proportion of high-risk SMM patients with undetectable minimal residual disease (MRD) at 6 months, 12 months, and thereafter every 12 months up to 5 years after cilta-cel administration as well as the sustained undetectable MRD rate in the intent-to-treat (ITT) population; ii) to annotate frequency and severity of adverse events (AE) and serious adverse events (SAE), as well as data from laboratory tests aslo related with safety such as Immunoglobulin (Ig) G levels, complete blood count (CBC) cytopenia adn T-cell populations. Secondary objectives are related with response to therapy and will measure different categories of response and survival.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Be ≥18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place) at the time of informed consent.
• High-risk SMM defined as having 1 of the following 2 criteria: i) High-risk per "Mayo 20-2-20" criteria defined as presence of any ≥2 of the following:
• Serum M-protein ≥2 gm/dL
• Involved to uninvolved FLC ratio ≥20
• BMPC % ≥20% to <40% OR ii) Presence of ≥95% of BMPC with an aberrant phenotype within the BMPC compartment and immunoparesis present defined as a reduction of at least 25% below the lower normal limit for ≥1 uninvolved immunoglobulin isotype (only IgG, IgA and IgM will be considered).
• Have an Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤1.
• Have an estimated glomerular filtration rate (eGFR), based on the Modified Diet in Renal Disease (MDRD) 4-variable formula or 24-hour urine collection of ≥40 mL/min during the screening period.
• Laboratory values obtained <21 days prior to Screening: i) Total bilirubin ≤2.0 mg/dL ii) Aspartate aminotransferase (AST) ≤3 x upper limit of normal (ULN) iii) Alanine transaminase (ALT) ≤3 x ULN
• Hemoglobin ≥8.0 g/dL (≥5 mmol/L) (without prior red blood cell [RBC] transfusion within 7 days before the laboratory test; recombinant human erythropoietin use is permitted). For subjects who meet the inclusion criteria at screening, transfusion of RBCs is permitted after screening as needed to maintain a hemoglobin level ≥8.0 g/dL.
• Neutrophils ≥1.0 × 109/L (prior growth factor support is permitted but must be without support in the 7 days prior to the laboratory test)
• Platelets ≥75 × 109/L (must be without transfusion support in the 7 days prior to the laboratory test)
• Lymphocyte count ≥0.3*109/L
• Participants should be seronegative for human immunodeficiency virus (HIV) or have controlled disease if seropositive.
• A female participant of childbearing potential must have a negative serum pregnancy test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study.
• A female participant must be either of the following: i) Not of childbearing potential ii) Of childbearing potential and practicing at least 1 highly effective method of contraception throughout the study and through 6 months after the last dose of study treatment. If a female participant becomes of childbearing potential after the start of the study, the female participant must comply with ii).
• A female participant using oral contraceptives should use an additional barrier contraceptive method.
• A female participant must agree not to donate eggs (ova, oocytes) or freeze for future use for the purposes of assisted reproduction during the study and for a period of 6 months after receiving the cilta-cel infusion. Female participants should consider preservation of eggs prior to study treatment as anti-cancer treatments may impair fertility.
• A male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person during the study and for 1 year after receiving the cilta-cel infusion. If the male participant's partner is a female of childbearing potential, the male participant must use condoms (with or without spermicide) and the female partner of the male participant must also be practicing a highly effective method of contraception. A male participant who is vasectomized must still use a condom (with or without spermicide), but the partner is not required to use contraception.
• A male participant must agree not to donate sperm for the purposes of reproduction during the study and for 1 year after receiving the last dose of study treatment. Male participants should consider preservation of sperm prior to study treatment as anti-cancer treatments may impair fertility.
• A male participant must agree not to plan to father a child while enrolled in this study or within 1 year after the last dose of study treatment.
• Must sign an informed consent form (ICF) indicating that the participant understands the purpose of, and procedures required for, the study and is willing to participate in the study
• An additional ICF will be collected to get participants authorization to collect the necessary samples for performing the Biological studies indicated in this protocol.
• Be willing and able to adhere to the lifestyle restrictions specified in this protocol.

You may not qualify if…

• History of uncontrolled illness, including but not limited to MGUS, standard risk smoldering myeloma, active myeloma by current IMWG definition, light chain amyloidosis with organ involvement or patients with extramedullary disease.

• Known allergies, hypersensitivity, or intolerance to cilta-cel or its excipients.
• Participant had major surgery or had significant traumatic injury ≤14 days prior to Cycle1Day1.
• If any of the following exist at screening, participant will be excluded because this trial involves an investigational agent whose genotoxic, mutagenic, and teratogenic effect on the developing fetus and newborn are unknown:
• i) Pregnant women ii) Nursing women iii) Men or women of childbearing potential who are unwilling to employ adequate contraception
• Other comorbidity which would interfere with subject's ability to participate in trial, eg, uncontrolled infection, uncompensated heart, or lung disease.
• Any medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol.
• History of neurodegenerative disease (eg, Parkinson or stroke within 6 months).
• Medical history of treatment for another malignancy <2 years before trial enrollment, other concurrent chemotherapy, or any ancillary therapy considered investigational. Note: Bisphosphonates are considered supportive care rather than therapy and are thus allowed while on protocol treatment.
• Known seropositive for or active viral infection with HIV, HBV, hepatitis C virus (HCV), or SARS-CoV-2 (Coronavirus Disease 2019 [COVID-19]).
• i) Participants who are positive for SARS-COV-2 antibody, HIV1 and 2 antibody, hepatitis B core antibody (HBc), or hepatitis B surface antigen (HBsAg) must have a negative polymerase chain reaction (PCR) result before enrollment. Those who are PCR positive will be excluded.
• ii) Participants who are positive for HIV1 or 2 infections, with undetectable viral load and on stable antiretrovirals, will not be excluded.
• iii) Participants with past HCV infection need at least 12 months of sustained virologic response and be negative for RNA to enter.
• iv) Patients with a high-risk of HBV reactivation (eg, negative for HBV antigen but positive for chronic HBV, with or without anti-serum HBV) must be monitored with DNA and ALT/AST).
• Any condition for which, in the opinion of the investigator, participation would not be in the best interest of the participant (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
• NOTE: Investigators must ensure that all study enrollment criteria have been met at screening. If a participant's clinical status changes (including any available laboratory results or receipt of additional medical records) after screening but before the first dose of study intervention is given such that the participant no longer meets all eligibility criteria, then the participant must be excluded from participation in the study.
