About this study

Official title: Phase 1/2 Study of Daratumumab, Bortezomib, Dexamethasone With or Without Venetoclax in Relapsed/Refractory Multiple Myeloma With Assessment for t(11;14) Status

This phase I/II trial studies the side effects and best dose of venetoclax when given together with daratumumab, bortezomib, and dexamethasone, and how well they work in treating patients with multiple myeloma that has come back (relapsed) or does not respond to treatment (refractory). Drugs used in chemotherapy, such as venetoclax and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving venetoclax with daratumumab, bortezomib, and dexamethasone may work better in treating patients with relapsed or refractory multiple myeloma compared to standard of care treatment, including chemotherapy.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the dose limiting toxicities and the recommended phase II dose of venetoclax in combination with daratumumab, bortezomib, and dexamethasone for patients with relapsed/refractory multiple myeloma. (Phase I) II. To evaluate the safety of venetoclax (VEN) in combination with bortezomib and dexamethasone (DVd). (Phase I) III. To compare efficacy of DVd-VEN versus DVd as measured by minimal residual disease negative rate after 8 cycles of therapy. (Phase II) IV. To inform the role of t(11;14) as a biomarker in a subsequent evaluation of the regimen. (Phase II)

SECONDARY OBJECTIVES:

  1. To compare rates of very good partial response between arms. II. To assess improvement in progression-free and overall survival with the addition of VEN.

III. To evaluate the safety of VEN in combination with DVd and compare overall toxicity rates between arms.

IV. To assess association of cycle 8 minimal residual disease (MRD) status with overall and progression-free survival.

  1. To estimate the impact of t(11;14) status on very good partial response, overall and progression-free survival.

EXPLORATORY OBJECTIVES:

  1. To measure treatment exposure and adherence. II. To estimate time to progression with the addition of VEN. III. To measure MRD levels longitudinally and assess the kinetics of relapse. IV. To assess association of MRD status after 8 cycles with survival outcomes. V. To evaluate agreement and discordance between methods determining disease-free status.

What is being measured

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

  1. Maximum tolerated dose of venetoclax in combination with daratumumab, bortezomib and dexamethasone (Phase I)

    Highest dose at which fewer than one-third of patients experience a dose-limiting toxicity.

    Measured: Up to 35 days

  2. Minimal residual disease (MRD) negative status (Phase II)

    Per revised International Myeloma Working Group (IMWG) response criteria for next-generation sequencing (NGS) methods.

    Measured: After cycle 8

Secondary outcomes (5)

  1. Overall survival (OS) (Phase II)

    OS distributions will be estimated using Kaplan-Meier (KM) methods and compared between treatment arms with the log-rank test. Stratified cox proportional hazards regression will produce a treatment hazard ratio estimate. Median OS by treatment arm with 95% confidence intervals will be reported.

    Measured: From randomization to death due to any cause, or censored at the date last known alive, assessed up to 10 years

  2. Progression-free survival (PFS) (Phase II)

    PFS distributions will be estimated using KM methods and compared between treatment arms with the log-rank test. Stratified cox proportional hazards regression will produce a treatment hazard ratio estimate. Median PFS by treatment arm with 95% confidence intervals will be reported.

    Measured: From randomization until the earlier of progression or death due to any cause, or censored at date of last disease evaluation, assessed up to 10 years

  3. Best response (Phase II)

    Will be based on standard IMWG criteria. Response will be tabulated by category. Response rates of very good partial response or better will be compared using the Fisher's exact test.

    Measured: Up to cycle 8

  4. Time to progression (TTP) (Phase II)

    TTP in each arm will be estimated using Kaplan-Meier methods and compared between arms with the log-rank test.

    Measured: From randomization to progression, or censored at the date of last disease evaluation, assessed up to 10 years

  5. Incidence of adverse events (Phase II)

    Will be assessed per Common Terminology Criteria for Adverse Events version 5.0. Will compare worst grade 3 or higher non-hematologic and overall treatment-related toxicity rates between arms using the Fisher's exact test.

    Measured: Up to 10 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Bortezomib, Daratumumab and Dexamethasone in people with Recurrent Plasma Cell Myeloma and Refractory Plasma Cell Myeloma, run by National Cancer Institute (NCI) at 3 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 52 inclusion and 0 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: withdrawn, as of the sponsor's last update on 26 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum tolerated dose of venetoclax in combination with daratumumab, bortezomib and dexamethasone (Phase I) (time frame: Up to 35 days). 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?

On the ClinicalTrials.gov record for NCT03701321.

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 26 Sep 2023.
