About this study

Official title: MMRC Horizon Two: A Phase II Randomized Adaptive Platform Trial Integrating Novel Therapies in High-Risk-Newly Diagnosed Multiple Myeloma (MMRC-100)

The Multiple Myeloma Research Consortium (MMRC) Horizon Two trial is a master protocol, multi-center, phase II randomized adaptive platform trial designed to efficiently evaluate multiple investigational therapies in high-risk newly diagnosed multiple myeloma patients using an integrated and patient-centric clinical research platform that enables longitudinal learning and sharing of knowledge and investigates multiple novel therapeutic strategies within one trial platform.

Read the detailed description

The master protocol has broad scope and substantial flexibility, allowing each investigational arm within the platform to have its own design. The master protocol specifies general principles but the analysis plan for each investigational arm will be specified in its appendix. Details outlined in each investigational arm's appendix will include any co-primary endpoints (if applicable), the comparator arm, sample size and justification, inclusion of a safety run-in (if required), and any potential adaptations within the appendix. Accrual to an investigational arm will terminate in accord with its appendix.

As an adaptive platform trial, MMRC Horizon Two will evaluate multiple investigational arms against common controls. It is expected that the common controls may vary over time as standard of care therapy evolves. An initial common control arm will be specified in the control arm appendix. Changes in the common controls will be made through amendments to this appendix.

All patients will be randomized to an arm in the study. The default for the platform will be equal randomization to all arms that a patient is eligible. However, when there are more than two investigational arms and response adaptive randomization is deemed beneficial, it may be implemented in the trial.

Participants will be on study for 5 years from the date of randomization, inclusive of treatment and follow-up periods. Specifics on treatment duration and duration of follow up will be included in the respective arm appendix.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sustained measurable residual disease (MRD) negativity

    Sustained MRD negativity is defined as MRD negativity at a minimum threshold of one myeloma cell in one hundred thousand nucleated bone marrow cells at MRD assessments

    Measured: 2 years post randomization

  2. Progression Free Survival

    PFS is defined as time from randomization to disease progression or death from any cause. Participants who have not progressed or died are censored at the date last known progression-free.

    Measured: through study completion, roughly 5 years

Secondary outcomes (7)
  1. Objective response rate (ORR)

    ORR is defined as the percentage of people who have achieved a partial response (PR) or better according to the IMWG criteria within the defined period of time on trial.

    Measured: 2 years

  2. Best overall response

    Best overall response (Stringent Complete Response [sCR], Complete Response [CR], Very Good Partial Response [VGPR], Partial Response [PR], Stable Disease [SD], Progressive Disease [PD]) by International Myeloma Working Group Response Criteria.

    Measured: 2 years

  3. Two-year progression free survival rate

    Two-year progression free survival rate is defined as the proportion of participants alive and progression-free 24 months after randomization.

    Measured: 24 months after randomization

  4. Overall survival (OS)

    OS is defined as the time from randomization to death. Alive participants are censored at the date last known alive.

    Measured: through study completion, average of 5 years

  5. Duration of response (DoR)

    DoR is defined as time from the first observation of a confirmed response [Stringent Complete Response (sCR), Complete Response (CR), Very Good Partial Response (VGPR), or Partial Response (PR)] to first documentation of disease progression or death. Participants who have not progressed or died are censored at the date last known progression-free. The start date for DoR is the date the response was first observed, not the date of confirmation.

    Measured: 2 years

  6. 12-month measurable residual disease (MRD) negativity

    12-month MRD negativity is defined as MRD negativity at a minimum threshold of one myeloma cell in one hundred thousand nucleated bone marrow cells at MRD assessment at disease restaging 1 (12 months±3 months from randomization). Measured using ClonoSEQ's standardized, commercial, next generation sequencing assay (preferred) or commercial multi-color flow cytometry.

    Measured: 12 months from randomization

  7. Frequency and intensity of (serious) adverse events (S)AEs

    Assessed by NCI CTCAE version 5.0, including a focus on hematologic clinical laboratory abnormalities and changes.

    Measured: through study completion, an average of 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bispecific Monoclonal Antibody and Triplet Therapy and Monoclonal Antibody with Stem Cell Transplant in people with High Risk Newly Diagnosed Multiple Myeloma, run by Multiple Myeloma Research Consortium at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 35 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jessica Vandermark (2036520457, vandermarkj@themmrf.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sustained measurable residual disease (MRD) negativity (time frame: 2 years post randomization). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026.
