Detailed Description
PRIMARY OBJECTIVE:
I. To determine if quadruplet induction therapy followed by autologous stem cell transplantation, consolidation with teclistamab, a BCMA-targeted, T-cell redirecting bispecific antibody, and doublet maintenance treatment will improve overall survival compared to those receiving standard of care consolidation therapy (i.e. daratumumab, carfilzomib, lenalidomide, and dexamethasone [D-KRd]).
SECONDARY OBJECTIVES:
I. To evaluate the progression free survival of quadruplet induction, autologous stem cell transplantation, consolidation, and doublet maintenance therapy.
II. To evaluate the safety of quadruplet induction, autologous stem cell transplantation, consolidation, and doublet maintenance therapy.
III. To evaluate response rates per International Myeloma Working Group (IMWG) criteria (overall response rate, partial response, very good partial response, complete response, stringent complete response).
EXPLORATORY OBJECTIVE:
I. To evaluate minimal residual disease negativity by next generation sequencing (10^-5 and 10^-6) after induction, autologous stem cell transplant, consolidation, and after 1 and 2 years of maintenance treatment.
OUTLINE:
INDUCTION THERAPY (CYCLES 1-4): Patients receive daratumumab and recombinant human hyaluronidase (daratumumab and hyaluronidase-fihj) subcutaneously (SC) on days 1, 8, 15, and 22 of cycles 1 and 2 and days 1 and 15 of cycles 3 and 4, carfilzomib intravenously (IV) on days 1, 8, and 15 of each cycle, lenalidomide orally (PO) once daily (QD) on days 1-21 of each cycle, and dexamethasone PO on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days in for up to 4 cycles in the absence of disease progression or unacceptable toxicity.
AUTOLOGOUS STEM CELL TRANSPLANT: Within 60 days of completing induction therapy, patients undergo stem cell mobilization using recombinant granulocyte colony-stimulating factor SC and plerixafor SC followed by stem cell collection according to standard of care. Patients then receive melphalan IV followed by autologous hematopoietic stem cell transplant (autoHSCT).
CONSOLIDATION THERAPY (CYCLES 5-12): Patients are randomized to 1 of 2 arms for consolidation therapy, to start within 120 days of autoHSCT.
ARM 1: Patients receive daratumumab and hyaluronidase-fihj SC on days 1 and 15 of cycles 5-6 and on day 1 of cycles 7-12, carfilzomib IV on days 1, 8, and 15 of each cycle, lenalidomide on days 1-21 of each cycle, and dexamethasone PO on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity.
ARM 2: Patients receive teclistamab SC on days 1, 3, 7, and 15 of cycle 5, once weekly thereafter for cycles 5-6, every 2 weeks in cycles 7-10, and every 4 weeks in cycles 11-12. Cycles repeat every 28 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity.
MAINTENANCE THERAPY (CYCLES 13-36): Within 60 days of completing consolidation therapy, patients receive carfilzomib IV on days 1 and 15 of each cycle and lenalidomide PO QD on days 1-21 of each cycle. Cycles repeat every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.
Patients also undergo transthoracic echocardiography (TTE) at screening and then as clinically indicated and undergo bone marrow biopsy and aspiration, collection of blood samples, and fludeoxyglucose F-18 (FDG) positron emission tomography (PET)/computed tomography (CT), magnetic resonance imaging (MRI), and/or CT throughout the trial.
After completion of study treatment, patients are followed up every 3 or 6 months for up to 5 years from registration.

- No history of clinically significant cardiopulmonary disease resulting from prior proteosome inhibitor therapy
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
Not pregnant and not nursing, because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn, before study entry, the following criteria must be met
Female of childbearing potential (FCBP) is a female who: 1) has achieved menarche (first menstrual cycle) at some point, 2) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries), or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time during the preceding 24 consecutive months). * Female of childbearing potential (FCBP):
- Must use a contraceptive method that is highly effective (with a failure rate of < 1% per year), preferably with low user dependency during the intervention and agrees to not donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention
- Given the risk of teratogenicity with immunomodulatory drugs (IMiD), females of child-bearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 25 mIU/mL within 10-14 days prior to, and again within 24 hours of starting lenalidomide, and must either commit to continued abstinence from heterosexual intercourse or being two acceptable methods of birth control, one highly effective method and one additional effective method at the same time, at least 28 days before she starts taking lenalidomide. Examples of highly effective methods are intrauterine device, hormonal contraceptives, tubal ligation, or partner's vasectomy. Examples of barrier method are male condom, diaphragm, or cervical cap. FCBP must also agree to ongoing pregnancy testing. Men must agree to use latex condom during sexual contract with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum frequency of 28 days about pregnancy precautions and risk of fetal exposure
- The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with a nearly undetected pregnancy
Non-childbearing potential is defined as follows (by other than medical reasons):
- ≥ 45 years of age and has not had menses for > 1 year
- Patients who have been amenorrhoeic for < 2 years without history of hysterectomy and oophorectomy must have a follicle stimulating hormone value in the postmenopausal range upon screening evaluation
- Post-hysterectomy, post-bilateral oophorectomy, or post-tubal ligation. Documented hysterectomy or oophorectomy must be confirmed with medical records of the actual procedure or confirmed by an ultrasound. Tubal ligation must be confirmed with medical records of the actual procedure
Male patients must agree to use an adequate method of contraception for the duration of the study and for 6 months afterwards.
Male participants: Contraceptive use should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Male participants are eligible to participate if they agree to the following during the intervention period and for 6 months after the last dose of study treatment to allow for clearance of altered sperm:
Refrain from donating sperm, PLUS, either:
- Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent, OR
Must agree to use contraception/barrier as detailed below:
- Agree to use a male condom, even if they have undergone successful vasectomy, and female partner to use an additional highly effective contraceptive method with a failure rate of < 1% per year as when having sexual intercourse with a woman of childbearing potential (including pregnant females)
- Patients may not have polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome, Waldenström's macroglobulinemia, or symptomatic amyloidosis. Amyloidosis found in skin or lymph nodes ("non-vital organs"), or incidental observation of amyloidosis on bone marrow biopsy, are permissible
- Clinically significant adverse effects from any prior oncologic treatment (e.g., prior surgery, radiotherapy, or other antineoplastic therapy) must have resolved or have been determined to be clinically stable per the investigator
- Patients with known HIV infection on effective anti-retroviral therapy with undetectable viral load within 6 months prior to registration are eligible for this trial
- For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
- Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load

Measure Description |
Time Frame |
|---|---|---|
|
Overall survival (OS)
Time Frame: From randomization to the time of death due to any cause, assessed up to 5 years
|
The time to event outcome of overall survival will be evaluated and compared using a log-rank test to compare differences between arms.
OS distributions will be evaluated graphically using the methods of Kaplan and Meier, along with estimation of the 3-year OS rates with corresponding 95% confidence intervals and other time points of interest.
In a secondary manner, Cox regression models will also be used to evaluate differences in OS between treatment arms when adjusting for factors of interest as well as stratifying on the stratification factors including prior treatment status and t(11;14) status.

Measure Description |
Time Frame |
|---|---|---|
|
Incidence of adverse events
Time Frame: Up to 5 years
|
Adverse events (AEs) will be summarized per the National Cancer Institute Common Terminology Criteria for Adverse Events version 5, and where toxicities will be defined as adverse events that are deemed to be at least possibly treatment-related (i.e., attribution of "possibly", "probably", or "definite").
Note that some AEs will be defined using other criteria where specified.
The maximum grade for each type of treatment-related AE will be recorded for each patient, and the frequency of each will be summarized across all patients for the induction phase, and by treatment arm for the consolidation and maintenance phases of treatment.
Frequency tables and graphical evaluations of AEs and treatment-related AEs will be summarized and evaluated to assess if there are any patterns or differences in the rates or types of AEs including, but not limited to, AEs of special interest including cytokine release syndrome, neurotoxicity, and second primary malignancies.
|
Up to 5 years
|
|
Progression free survival (PFS)
Time Frame: From randomization to the time of progression and/or death due to any cause, assessed up to 5 years
|
Will use Kaplan-Meier analyses and Cox regression models to evaluate this endpoint and how the PFS distributions differ between the treatment arms.
|
From randomization to the time of progression and/or death due to any cause, assessed up to 5 years
|
|
Overall response rate
Time Frame: Up to 5 years
|
Overall response rate will be summarized for each of the treatment arms and defined as the number of patients who achieve at least a partial response to therapy divided by the total number of patients treated on that arm.
Will summarize the incidence and depth of objective response both post-induction as well as post-consolidation.
Response rates will be calculated along with 95% binomial confidence intervals for each of the t(11;14) subjects and treatment arms.

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Minimal residual disease (MRD) negativity
Time Frame: At baseline, post-induction, post-transplant, post-consolidation, and post-maintenance
|
MRD negativity will be evaluated over the course of the trial when a bone marrow biopsy and aspirate is obtained to confirm complete response or better and will be summarized based on treatment arm and t(11;14) status.
Repeated measures models will also be used to evaluate changes over time along with graphical analyses to assess patterns or differences based on subgroup and/or treatment and how these relate to key therapeutic milestones.
Time-dependent covariate analyses will also be used to explore the relationship of this outcome and how these longitudinal outcomes may correspond to PFS and OS in these patients.
