About
The purpose of this research is to learn whether using teclistamab and talquetamab at different time points will improve survival in participants with high-risk Multiple Myeloma (MM).
The treatment on this study will consist of Induction chemotherapy and stem cell collection, Immunotherapy 1 chemotherapy and Immunotherapy 2 chemotherapy. For participants whose testing show they are Minimal Residual Disease (MRD) positive (still have myeloma cells present in the bone marrow testing), a Melphalan-based stem cell transplant will be performed. For participants whose testing show they are MRD negative, the stem cell transplant will not be performed. All participants will go on to receive Immunotherapy 3 chemotherapy, Immunotherapy 4 chemotherapy, and Maintenance therapy.
Full description
The two primary objectives are to determine (1) the Complete Response Rate (CRR) and (2) the 2-year Progression-Free Survival (PFS) percentage in participants with high-risk multiple myeloma (HRMM) treated with the sequential use of Bispecific Antibodies.
Overview of Study Design:
We will implement a Phase 2 clinical trial to explore the use of early and late bispecific antibodies consolidation and extended/maintenance therapy as a way of overcoming intraclonal heterogeneity and improving PFS in HRMM. Subjects will receive induction treatment with daratumumab (Dara)-KRD for 4 cycles to obtain immediate disease control, reduce tumor bulk and minimize the risk of subsequent cytokine release syndrome (CRS). Peripheral blood stem cell (PBSC) will be harvested after induction treatment. Immune therapy will consist of teclistamab+daratumumab followed sequentially by talquetamab+daratumumab each for 4 cycles. Next, an MRD-based consolidation approach will be utilized where subjects who are MRD-negative (a threshold of 10^5) will be given teclistamab+daratumumab followed by talquetamab+daratumumab each for 4 cycles followed by 2-year fixed duration treatment with daratumumab and lenalidomide extended/maintenance therapy for a maximum of 24 cycles, or until myeloma progression. Subjects who are MRD-positive (a threshold of 10^5) will receive a single melphalan (MEL)-based hematopietic stem cell transplantation (HSCT) followed by teclistamab+daratumumab followed by talquetamab+daratumumab each for 4 cycles followed by a 2-year fixed duration treatment with daratumumab and lenalidomide extended/maintenance therapy for a maximum of 24 cycles, or until myeloma progression. Minimal residual disease (MRD) status with classification threshold of 10^5 will be assessed by standardized flow cytometry.

Inclusion criteria
-
Patients must have newly diagnosed active MM requiring treatment. Patients with a previous history of smoldering myeloma will be eligible if there is evidence of PD requiring initiation of treatment.
-
Patients must be either untreated or have not received more than two months of MM therapy. However, bisphosphonates and localized radiation are allowed.
-
Patients must have clinical features of high-risk disease, at time of initial diagnosis or initial assessment prior to enrollment, which may include one or more of the following:
- High-risk cytogenetic abnormalities, including t(4;14), t(14;16), t(14;20), del17p13, del1p, or gain 1q with del1p by FISH, with a cutoff point of 20% or greater.
- Beta-2-microglobulin >5.5 mg/L with normal kidney function test per the institutional reference.
- Presence of extramedullary disease defined as soft tissue plasmacytoma (excluding Paramedullary/Paraskeletal plasmacytoma)
- ≥ 3 focal lesions on F18-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging
- LDH ≥ 360 U/L (Rule out hemolysis and infection; contact Principal Investigator if any doubt.)
- Circulating plasma cells ≥5 percent of white blood cells on conventional peripheral blood smear (manual white blood cell differential count) or peripheral blood flow cytometry.
-
ECOG ≤ 2, unless solely due to symptoms of MM-related bone disease.
-
Patients must have a platelet count ≥ 50,000/μL and hemoglobin level of ≥7.5 g/dl and absolute neutrophilic count (ANC) of 1.0x10^9/L unless lower levels are explained by extensive BM plasmacytosis.
-
Patients must be at least 18 years of age and not older than 75 years of age at the time of consent.
-
Patients must have adequate renal function with baseline serum creatinine level < 3 mg/dL and estimated creatinine clearance ≥30 mL/min. Creatinine clearance may be calculated using Cockcroft-Gault, eGFR (MDRD), or CKD-epi formula and baseline Alanine Aminotransferase (ALT) < 3x Upper Limit of Normal (ULN).
-
Patients must have an ejection fraction by echocardiogram (ECHO) or Multigated Acquisition (MUGA) scan ≥ 45%
-
Patients must have adequate pulmonary function studies > 50% of predicted on mechanical aspects (FEV1, FVC, etc.) and diffusion capacity (DLCO) > 50% of predicted. If the patient is unable to complete pulmonary function tests (PFT) due to MM related pain or other conditions, an exception may be granted if the Principal Investigator documents that the patient is a candidate for high dose therapy.
-
Patients must have signed an IRB-approved informed consent form (ICF) indicating their understanding of the proposed treatment and that the protocol has been approved by the IRB.
-
Female subjects must use effective methods of birth control during the course of the study and for 6 months after stopping study medications.
-
Female subjects must not donate eggs during the study and for 6 months after the last dose of study medications.
-
Male subjects must not donate sperm during the study and for 3 months after the last dose of study medications.
Exclusion criteria
-
Poorly controlled hypertension, diabetes mellitus, or other serious medical or psychiatric illness that could potentially interfere with the completion of treatment according to this protocol.
-
Patients must not have prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, low Gleason score prostate cancer on active surveillance or having had surgery/radiation with curative intent within one year of consent or other cancer for which the patient has not received treatment for one year prior to consent. Other cancers will only be acceptable if the patient's life expectancy exceeds five years.
-
Pregnant, or breast-feeding, or planning to become pregnant while enrolled in this study or within 3 months after the last dose of any component of the treatment regimen. Or subject is a man who plans to father a child while enrolled in this study or within 3 months after the last dose of any component of the treatment regimen. Women of childbearing potential (WOCBP) must have a negative pregnancy documented within one week of consent. Subjects of reproductive potential may not participate unless they have agreed to use an effective contraceptive method.
-
Chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) <50% of predicted normal. Note that FEV1 testing is required for subjects suspected of having COPD and patients must be excluded if FEV1 is <50% of predicted normal.
-
Moderate or severe persistent asthma within the past 2 years, or uncontrolled asthma of any classification. Note that patients who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate in the study.
-
Active autoimmune disease
-
Active systematic viral, fungal or bacterial infection, requiring systemic therapy.

-
Patient is:
- seropositive for human immunodeficiency virus (HIV)

Subjects with resolved infection (i.e., subjects who are HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs] must be screened using real-time polymerase chain reaction (PCR) measurement of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) levels. Those with active infection will be excluded. Subjects with serologic findings suggestive of HBV vaccination (anti-HBs positivity as the only serologic marker) and a known history of prior HBV vaccination, do not need to be tested for HBV DNA by PCR.
- Seropositive for hepatitis C (except in the setting of a sustained virologic response [SVR], defined as aviremia at least 12 weeks after completion of antiviral therapy).
