About this study

Official title: A Phase 1 Study of Venetoclax With Obinutuzumab and Magrolimab (VENOM) in Relapsed and Refractory Indolent B-cell Malignancies

Background:

B-cell lymphoma is a cancer of certain white blood cells (called lymphocytes). These cells are found in lymph nodes. The cancer can cause enlargement of the lymph nodes leading to pain and discomfort. Swollen lymph nodes can also press on nearby organs such as liver and kidneys which can affect normal functioning of the organs. Researchers think that a new combination of drugs may be able to help.

Read more

Objective:

To find out if it is safe to give the combination of Magrolimab, Obinutuzumab and Venetoclax to people with B-cell lymphomas.

Eligibility:

Adults age 18 and older with an indolent B-cell lymphoma whose disease has returned or progressed after other treatment. Indolent B-cell lymphoma for this protocol is defined as having either follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma or marginal zone lymphoma.

Design:

Participants will be screened under a separate protocol.

Participants will have 28-day 'cycles' of treatment. They will take Venetoclax by mouth daily. They will get Obinutuzumab and Magrolimab by intravenous (IV) infusion. Treatment will last for about 8 months. They may be able to have more cycles of treatment if their cancer is responding well.

Participants will have physical exams, medical histories, and medicine reviews. Data about how they function in their daily activities will be obtained. They will have blood and urine tests. They may have bone marrow tests.

Participants will have imaging scans. These will include computed tomography (CT) and/or magnetic resonance imaging (MRI) scans and positron emission tomography (PET) scans.

Participants may give a cheek swab or saliva sample. They may give tumor tissue and bone marrow samples. These samples may be used for gene testing.

Participants will have a follow-up visit about 30 days after treatment ends. Then they will have visits every 3 months for the first 2 years, every 6 months for the next 3 years, and then yearly after that.

Read the detailed description

Background:

  • Indolent B-cell malignancies are associated with frequent disease relapse
  • Standard frontline therapy includes a monoclonal anti-cluster of differentiation 20 (CD20) antibody with or without chemotherapy; novel targeted therapies have changed the treatment landscape and are preferred therapy for some patients with high-risk molecular features
  • Targeted therapies given indefinitely add to drug resistance, treatment-emergent toxicities, and non-compliance
  • Cluster of differentiation 47 (CD47) is a rational target for indolent B-cell malignancies; CD47 expression is higher in tumor cells than normal B-cells, and blocking CD47 results in phagocytosis of tumor cells
  • Magrolimab is an anti-CD47 monoclonal antibody with activity in refractory indolent lymphomas when combined with rituximab (a first generation anti-CD20 monoclonal antibody)
  • Obinutuzumab is a novel anti-CD20 monoclonal antibody with enhanced binding to the Fc receptor that may improve antibody-dependent cell-mediated cytotoxicity (ADCC), and phagocytosis, when combined with magrolimab
  • We aim to test the safety and efficacy of venetoclax when added to the backbone of magrolimab and obinutuzumab in patients with relapsed or refractory indolent B-cell malignancies
  • Treatment duration will be response-adapted and time-limited in all patients

Objective:

-To determine the safety of the triplet combination of venetoclax, magrolimab and obinutuzumab in relapsed and refractory indolent B-cell malignancies

Eligibility:

  • Follicular lymphoma (FL) (grades 1-2, or 3a), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL) or chronic lymphocytic leukemia (CLL) with greater than or equal to 2 prior therapies, with at least one of those therapies containing an anti-CD20 monoclonal antibody
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2
  • Adequate bone marrow and organ function

Design:

  • Phase 1 study with expansion cohorts of up to 76 patients with relapsed or refractory FL, MZL, MCL or CLL
  • The safety profile of magrolimab, venetoclax, and obinutuzumab will first be determined in a dose-finding phase of up to 24 patients (6-12 patients with FL and 6-12 patients with MZL, MCL or CLL). Patients without dose-limiting toxicity (DLT) will receive an additional 5 cycles (total 6 cycles) of the triplet combination.
  • After dose-finding is completed, expansion cohorts of each histology will first receive magrolimab and obinutuzumab for 2 cycles in a window for translational research. After the window, venetoclax will be added and patients will receive 6 cycles (total 8 cycles) of the triplet combination.
  • Patients who achieve a complete response (CR) (after a total of 6 cycles of the triplet combination) will stop treatment and initiate active monitoring with radiologic imaging and assays for circulating tumor DNA (ctDNA); if these patients relapse, they can be retreated with 6 additional cycles. Patients who achieve partial response (PR) after 6 cycles of the triplet will continue for an additional 6 cycles; then, will initiate active monitoring.

What is being measured

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

  1. Number of Grades 3, 4, and/or 5 Dose-limiting Toxicities (DLT) Probably and/or Definitely Related to Triplet Combination Therapy

    Incidence of dose limiting toxicities (i.e., grade and frequency) to determine safety and tolerability were measured by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Grade is 3 is severe. Grade 4 is life threatening, and Grade 5 is death related to adverse event. A DLT is defined as any grade 3 or higher adverse event that is clinically relevant and deemed probably or definitely related to any of the study drugs or to the combination therapy and occurs during the venetoclax dose-finding period. Exceptions are non-hematologic grade 3 nausea, vomiting or diarrhea. Grade 3 fatigue, electrolyte disturbances, magrolimab or obinutuzumab infusion reactions, and/or grade 3 laboratory abnormalities. Hematologic grade 3 neutropenia, thrombocytopenia, anemia and hemolytic anemia. And/or grade 3 or 4 lymphopenia.

    Measured: 4 weeks for Arm 1 and 5 weeks for Arm 2

Secondary outcomes (6)

  1. Overall Response Rate (ORR) (Complete Response + Partial Response)

    ORR was determined and reported from individual cohorts and histological diagnosis. ORR was measured by the Lugano response criteria for Follicular Lymphoma, Mantle Cell Lymphoma and Marginal Zone Lymphoma; and the International Workshop on Chronic Lymphocytic Leukemia criteria for Chronic Lymphocytic Leukemia. Complete response is complete resolution of the lesion on imaging. Partial response is 50% or greater reduction in the maximum diameter of the lesion from its original tumor size on imaging. Disease progression is an increase of 50% or more in size of a previously involved site measuring ≥1.5 cm.

    Measured: From the start of the treatment until disease progression/recurrence, median follow-up of 17.4 months

  2. Duration of Response (DOR)

    DOR was estimated using Kaplan-Meier curves and reported along with a 95% confidence interval. DOR was measured from the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, death, or, in the absence of progressive disease (PD), date of last assessment. DOR was measured by the Lugano response criteria for Follicular Lymphoma, Mantle Cell Lymphoma and Marginal Zone Lymphoma; and the International Workshop on Chronic Lymphocytic Leukemia criteria for Chronic Lymphocytic Leukemia. Complete response is complete resolution of the lesion on imaging. Partial response is 50% or greater reduction in the maximum diameter of the lesion from its original tumor size on imaging. Disease progression is an increase of 50% or more in size of a previously involved site measuring ≥1.5 cm.

    Measured: From the start of the treatment until time of disease relapse, disease progression, or death, whichever occurs first, an average of 10.9 months.

  3. Event-free Survival (EFS)

    EFS was estimated using Kaplan-Meier curves and reported along with a 95% confidence interval. EFS is defined as the duration of time from the date of study enrollment until time of disease relapse, disease progression, alternative anti-lymphoma therapy including radiation, or death, whichever occurs first, measured by the Lugano response criteria for Follicular Lymphoma, Mantle Cell Lymphoma and Marginal Zone Lymphoma; and the International Workshop on Chronic Lymphocytic Leukemia criteria for Chronic Lymphocytic Leukemia. Disease progression is an increase of 50% or more in size of a previously involved site measuring ≥1.5 cm.

    Measured: From the start of the treatment until time of disease relapse, disease progression, alternative anti-lymphoma therapy including radiation, or death, whichever occurs first, up to 20 months

  4. Progression-free Survival

    PFS was estimated using Kaplan-Meier curves and reported along with a 95% confidence interval. PFS is defined as the duration of time from the date of study enrollment until time of disease relapse, disease progression, or death, whichever occurs first. PFS was measured by the Lugano response criteria for Follicular Lymphoma, Mantle Cell Lymphoma and Marginal Zone Lymphoma; and the International Workshop on Chronic Lymphocytic Leukemia criteria for Chronic Lymphocytic Leukemia. Disease progression is an increase of 50% or more in size of a previously involved site measuring ≥1.5 cm.

    Measured: From the start of the treatment until time of disease relapse, disease progression, or death, whichever occurs first, an average of 13.9 months.

  5. Overall Survival (OS)

    OS was estimated using Kaplan-Meier curves and reported along with a 95% confidence interval. OS is defined as the time from study enrollment until death from any cause.

    Measured: From the start of the treatment until death from any cause, an average of 15.6 months.

  6. Percentage of Participants With Chronic Lymphocytic Leukemia (CLL) With Complete Molecular Remission (MRD Negativity)

    The percentage of participants who are MRD negative was determined by circulating tumor deoxyribonucleic acid (ctDNA) assay after therapy. Negative is undetectable CLL cells on peripheral blood flow cytometry after end of treatment.

    Measured: From the start of the treatment until disease progression/recurrence, an average of 3.3 months.

Who may be eligible to take part?

The sponsor lists 44 inclusion and 21 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: finished, as of the sponsor's last update on 4 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 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.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Feb 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Grades 3, 4, and/or 5 Dose-limiting Toxicities (DLT) Probably and/or Definitely Related to Triplet Combination Therapy (time frame: 4 weeks for Arm 1 and 5 weeks for Arm 2). 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 NCT04599634.

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 4 Feb 2025.
