Non-sterilized male partners of a female patient of childbearing potential must use male condom plus spermicide throughout this period. Cessation of birth control after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Female patients should also refrain from breastfeeding throughout this period
  • Male patients with a female partner of childbearing potential
  • Non-sterilized male patients who are not abstinent and intend to be sexually active with a female partner of childbearing potential must use a male condom plus spermicide from the time of screening throughout the total duration of the drug treatment and the drug washout period (180 days after the last dose of study treatment). However, periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Male patients should refrain from sperm donation throughout this period
  • Female partners (of childbearing potential) of male patients must also use a highly effective method of contraception throughout this period
  • Females of childbearing potential are defined as those who are not surgically sterile (i.e., bilateral salpingectomy, bilateral oophorectomy, or complete hysterectomy) or post-menopausal
  • Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
  • Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution
  • Women >= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago

About this study

Official title: MC198B, Phase II Study of a Combination Therapy of Acalabrutinib, Venetoclax and Durvalumab in Patients With Richter Transformation From Chronic Lymphocytic Leukemia (CLL)

This phase II trial tests whether acalabrutinib, venetoclax, and durvalumab work in treating patients with Richter transformation from chronic lymphocytic leukemia or small lymphocytic lymphoma. Richter transformation is a rare condition in which chronic lymphocytic leukemia or small lymphocytic lymphoma changes into a fast-growing type of lymphoma. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving acalabrutinib, venetoclax, and durvalumab may help improve survival in patients with Richter transformation.

PRIMARY OBJECTIVE:

  1. Determine the progression free survival (PFS) at 6 months of the combination therapy of acalabrutinib, venetoclax, and durvalumab in patients with Richter transformation from chronic lymphocytic leukemia (CLL).

SECONDARY OBJECTIVES:

  1. Determine the safety of the combination therapy of acalabrutinib, venetoclax and durvalumab in patients with Richter transformation from CLL.

II. Evaluate the overall response rate (ORR), complete response (CR) rate, and partial response (PR) rate of the above combination therapy.

III. Overall survival, PFS, and treatment free survival of this above combination therapy.

CORRELATIVE RESEARCH OBJECTIVES:

  1. Determine the biomarkers that predict clinical response of this above combination therapy.

II. Determine the immune profiles of patients while receiving this combination of therapy.

OUTLINE:

Patients receive acalabrutinib orally (PO) twice daily (BID) on days 1-28, durvalumab intravenously (IV) over 1 hour on day 1, and venetoclax PO once daily (QD) on days 1-28 of each cycle. Cycles repeat every 28 days for 12 cycles in the absence of disease progression or unacceptable toxicity.

MAINTENANCE: Patients receive acalabrutinib PO BID and venetoclax PO QD on days 1-90 of each cycle. Cycles repeat every 90 days for 4 cycles in the absence of disease progression or unacceptable toxicity.

Patients also undergo blood sample collection, bone marrow aspiration and biopsy, and positron emission tomography (PET)/computed tomography (CT) or CT throughout the study.

After completion of study treatment, patients are followed up at 30 days and then every 90 days until 5 years from study enrollment.

What is being measured

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

  1. Progression free survival

    Progression will be defined by Lugano positron emission tomography (PET)-computed tomography (CT) based criteria or chronic lymphocytic leukemia (CLL) criteria. The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Ninety-five percent confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner. If patients are censored prior to 6 months, a Kaplan Meier estimate for progression-free survival at 6 months along with the 95% confidence intervals will be reported.

    Measured: At 6 months (end of cycle 6). Each cycle is 28 days.

Secondary outcomes (5)

  1. Overall response rate

    Overall response rate (for both Richter transformation [RT] and CLL, calculated separately) will be estimated by the total number of patients who achieve a complete metabolic response (CMR)/partial metabolic response (PMR) or complete response (CR)/complete response with incomplete marrow recovery (CRi)/nodular partial response (nPR)/partial remission (PR) divided by the total number of evaluable patients. Exact binomial 95% confidence intervals for the true overall response rate will be calculated. The PR rate and CR rate will also be estimated.

    Measured: Up to 1 year

  2. Overall survival

    The distribution of overall survival will be estimated using the method of Kaplan-Meier.

    Measured: From registration to death due to any cause, assessed up to 5 years

  3. Progression-free survival (PFS)

    The distribution of progression-free survival will be estimated using the method of Kaplan-Meier. PFS estimates will be calculated at 3, 6, 12, and 24 months.

    Measured: From registration to progression or death due to any cause, assessed up to 2 years

  4. Treatment-free survival

    The distribution of treatment-free survival will be estimated using the method of Kaplan-Meier.

    Measured: From registration to subsequent treatment or death due to any cause, assessed up to 5 years

  5. Incidence of adverse events

    All eligible patients that have initiated treatment will be considered evaluable for assessing adverse event (AE) rate(s). Platelets and hemoglobin will be graded according to the Grading Scale for Hematologic Adverse Events in CLL Studies. The maximum grade for each type of AE will be recorded for each patient, and frequency tables will be reviewed to determine patterns. Additionally, the relationship of the AE(s) to the study treatment will be taken into consideration.

    Measured: Up to 30 days after last dose of study drug

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Acalabrutinib, Durvalumab and Venetoclax in people with Chronic Lymphocytic Leukemia and Richter Syndrome, run by Mayo Clinic at 1 site 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 48 inclusion and 60 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: under way, not looking for participants, as of the sponsor's last update on 5 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 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 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?

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?

Progression free survival (time frame: At 6 months (end of cycle 6). Each cycle is 28 days.). 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 NCT05388006.

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 5 Oct 2026; AzTrials last refreshed its copy on 8 Nov 2026.
