ClinConnect Summary

The MMRC Horizon One Adaptive Platform Trial is studying new treatments for patients with relapsed or refractory multiple myeloma, which is a type of blood cancer that has come back or is not responding to previous therapies. This trial is unique because it can adapt over time, meaning that new treatment options can be added as they become ready to test. The goal is to find out which therapies work best for different patients, helping to personalize care.

To participate in this trial, you must be at least 18 years old and have a confirmed diagnosis of multiple myeloma that has either relapsed or does not respond to certain prior treatments. You should also have measurable disease based on specific criteria. During the trial, participants will receive one of the investigational treatments and will be monitored regularly for safety and effectiveness. It’s important to note that there are specific health criteria you must meet to be eligible, and you’ll need to provide informed consent to join. If you or a loved one are considering participation, this trial could be a valuable opportunity to access new therapies while contributing to important research.

Eligibility criteria

  • Inclusion Criteria
  • For inclusion in the trial, all the following inclusion criteria must be fulfilled, as no waivers will be permitted:
  • Voluntarily agree to participate by giving written informed consent
  • ≥18 years of age
  • * Histologically confirmed multiple myeloma that is exposed, relapsed, or intolerant to one of each of the following classes of agents:
  • A proteasome inhibitor
  • An immunomodulatory drug
  • An anti-CD38-monoclonal antibody
  • Must have received between 1-4 lines of prior systemic therapy
  • Prior BCMA-directed antibody-drug conjugate (ADC) or chimeric antigen receptor (CAR)-T cell therapy allowed Note: A washout period of 6 months is required from prior anti-BCMA therapy. For BCMA CAR-T cell therapy, participants must be ≥ 6 months from lymphodepleting chemotherapy.
  • * Measurable disease, defined as one of the following:
  • M-protein ≥ 0.50g/dL (0.5 g/dL or above if IgA subtype)
  • Urine M-protein (Bence-Jones protein) ≥ 200 mg/24hours
  • Serum free light chain difference \> 100 mg/L
  • Biopsy proven plasmacytoma
  • For oligosecretory multiple myeloma, disease must be measurable by imaging (i.e., PET-CT, MRI)
  • ECOG performance status of 0-2
  • * Adequate organ function, as indicated by the following laboratory values:
  • Adequate hematological function, defined as ANC ≥ 1000/µL, platelet count ≥ 50,000/µL, and hemoglobin ≥ 8 g/dL (transfusion and/or growth factor support is allowed for hematologic parameters as long as the investigator deems the participant otherwise fit for screening)
  • Adequate hepatic function, defined as total bilirubin level \< 1.5 x institutional upper limit of normal (IULN) (except in participants with congenital bilirubinemia, such as Gilbert syndrome, in which case direct bilirubin \< 1.5-3.0 x IULN is required), AST ≤ 2.5 x IULN, and ALT ≤ 2.5 x IULN
  • Adequate renal function, defined as calculated creatinine clearance ≥ 30 mL/min per institutional standard (assessment method should be recorded, measured or C-G acceptable)
  • eGFR \> 30mL/min based on MDRD 4-variable formula calculation or creatinine clearance based measured by 24h urine collection
  • Corrected serum calcium \<14mg/dL or free ionized calcium \<6.5 mg/dL
  • * Persons of childbearing potential must have a negative serum pregnancy test at screening (within 72 hours of first dose of trial medication). Non-childbearing potential for a person assigned as female at birth is defined as 1 of the following:
  • ≥ 45 years of age and has not had menses for \>1 year
  • Amenorrheic for \> 2 years without a hysterectomy and/or oophorectomy and follicle-stimulating hormone value in the postmenopausal range upon pretrial (screening) evaluation
  • Status is post-hysterectomy, -oophorectomy, or -tubal ligation
  • Persons of childbearing potential must be willing to use highly effective contraceptive measures during sexual contact with a person assigned as male at birth starting with the Screening visit through 90 days after last dose of trial medication.
  • Note: Abstinence is acceptable if this is the established and preferred contraception for the participant.
  • -Persons assigned as male at birth with a partner(s) of childbearing potential must agree to use highly effective contraceptive measures throughout the trial starting with the Screening visit through 90 days after the last dose of trial medication is received. Persons assigned as male at birth with pregnant partners must agree to use a condom; no additional method of contraception is required for the pregnant partner.
  • Note: Abstinence is acceptable if this is the established and preferred contraception method for the participant.
  • Known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using New York Heart Association Functional Classification. To be eligible for this trial, participants should be Class 2 or better. Class 2 is defined as slight limitation of physical activity, in which ordinary physical activity leads to fatigue, palpitation, or dyspnea; the person is comfortable at rest.
  • Prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessments of the investigational arms are eligible for this trial.
  • Known HIV infection who are on effective anti-retroviral therapy with undetectable viral load within 6 months of screening and enrollment are eligible for this trial.
  • Evidence of chronic hepatitis B virus (HBV) infection must have an undetectable HBV viral load on suppressive therapy, if indicated.
  • History of hepatitis C virus (HCV) infection must have been treated and cured. For participants with known HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
  • Willing and able to comply with the requirements of the protocol.
  • Exclusion Criteria
  • For inclusion in Horizon, participants will not be eligible if any of the following criteria are met, as no waivers will be permitted:
  • * Major concurrent illness or organ dysfunction including but not limited to the following:
  • Plasma cell leukemia (the presence of ≥ 5% circulating plasma cells in peripheral blood smears)
  • Waldenström's macroglobulinemia
  • POEMS syndrome
  • Primary amyloid light-chain amyloidosis
  • History of allergy or known hypersensitivity to any of the trial therapies or any of their excipients, or contraindication to any of the trial therapies as outlined in the local prescribing information (e.g., United States Prescribing Information \[USPI\]).
  • Complete cord compression or CNS involvement
  • Active or history of autoimmune disease that requires systemic treatment within 2 years of the start of study drug (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs).
  • Note: Participants with diabetes type 1, vitiligo, psoriasis, or hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible
  • Received a live, attenuated vaccine within 4 weeks before the first dose of study drug. Non-live or nonreplicating vaccines authorized for emergency use (eg, COVID-19) by local health authorities are allowed.
  • Allogeneic tissue/solid organ transplant recipients with chronic GVHD requiring steroid equivalent dose of \> 20 mg prednisone
  • Active infection requiring treatment
  • History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the participant's participation for the full duration of the trial, or is not in the best interest of the participant to participate, in the opinion of the treating investigator
  • Psychiatric or substance abuse disorder that would interfere with cooperation with the requirements of the trial
  • Legally incapacitated or has limited legal capacity
  • Persons who are pregnant or lactating
