About this study

Official title: BACCI: A Phase II Randomized, Double-Blind, Placebo-Controlled Study of Capecitabine Bevacizumab Plus Atezolizumab Versus Capecitabine Bevacizumab Plus Placebo in Patients With Refractory Metastatic Colorectal Cancer

This randomized phase II trial studies how well capecitabine and bevacizumab with or without atezolizumab work in treating patients with colorectal cancer that is not responding to treatment and has spread to other places. Immunotherapy with monoclonal antibodies, such as atezolizumab and bevacizumab, may help the body?s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as capecitabine, 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. Giving atezolizumab with capecitabine and bevacizumab may be a better way in treating colorectal cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To estimate the efficacy of capecitabine/bevacizumab + atezolizumab, as compared with capecitabine/bevacizumab + placebo in refractory metastatic colorectal cancer (mCRC) as measured by progression-free survival (defined as the time of randomization to the first occurrence of progression based on Response Evaluation Criteria in Solid Tumors version 1.1, clinical progression, or death from any cause on study as determined by the investigator).

SECONDARY OBJECTIVES:

  1. To estimate the efficacy of capecitabine/bevacizumab + atezolizumab, as compared with capecitabine/bevacizumab + placebo in refractory mCRC as measured by objective response rate (defined as partial response plus complete response) as determined by the investigator using Response Evaluation Criteria in Solid Tumors version 1.1 and immune-related response criteria (irRC).

II. To estimate the efficacy of capecitabine/bevacizumab + atezolizumab as compared with capecitabine/bevacizumab + placebo in refractory mCRC as measured by overall survival (defined as death from any cause from the time of randomization until study completion).

III. To evaluate the safety and tolerability of atezolizumab in combination with bevacizumab and capecitabine in refractory mCRC as measured by the serious adverse events and adverse events >= grade 3 according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0.

CORRELATIVE OBJECTIVE:

  1. To explore any correlation between tissue and blood based biomarkers and clinical outcomes.

OUTLINE: Patients are randomized 2:1 to Arm I:Arm II.

ARM I (ATEZOLIZUMAB, BEVACIZUMAB, CAPECITABINE): Patients receive atezolizumab intravenously (IV) over 30-60 minutes on day 1, bevacizumab IV over 30-90 minutes on day 1, and capecitabine orally (PO) twice daily (BID) on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

ARM II (PLACEBO, BEVACIZUMAB, CAPECITABINE): Patients receive placebo IV over 30-60 minutes on day 1, bevacizumab IV over 30-90 minutes on day 1, and capecitabine PO BID on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, every 3 months until progressive disease, then every 6 months thereafter.

What is being measured

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

  1. Progression Free Survival (PFS)

    Assessed by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. The primary comparisons will be superiority of the active treatment for PFS of atezolizumab versus placebo. PFS will be compared between treatment arms using the un-stratified log-rank test at one-sided level of 0.10 and the p-value will be used for decision making. The hazard ratio (HR) for PFS will be estimated using a Cox proportional hazards model and the 95% confidence interval (CI) for the HR will be provided. Kaplan-Meier methodology will be used to estimate the median PFS for each treatment arm, and Kaplan-Meier curves will be produced. Progression is defined as any new lesion or increase by ≥20% of previously involved sites from nadir based on RECIST criteria.

    Measured: From randomization to first documentation of disease progression by RECIST v1.1, or death from any cause, assessed up to 20 months

Secondary outcomes (3)

  1. Overall Survival (OS)

    The distribution of survival time will be estimated using the method of Kaplan-Meier. OS will be compared between treatment arms using the unstratified log-rank test. OS medians, survival rates and HR will be estimated along with 95% confidence intervals.

    Measured: From randomization to death due to any cause, assessed up to 20 months

  2. Objective Response Rate

    The objective response rate is defined as the percentage of participants who achieve a partial response or compete response as assessed (partial response [PR] or complete response [CR] per RECIST v1.1) during treatment with study therapy. Rates of response will be compared across arms using a fisher's exact test for proportion. Point estimates will be generated for objective response rates within each arm along with 95% binomial confidence intervals. Complete response (CR): Disappearance of all evidence of disease, Partial response (PR): Regression of measurable disease and no new sites

    Measured: Up to 20 months

  3. The Number of Participants Who Experienced at Least One Grade 3 or Higher Adverse Event Deemed at Least Possibly Related to Treatment (Toxicity)

    The number of participants who experienced at least one grade 3 or higher adverse event deemed at least possibly related to treatment (toxicity) is reported below. Graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Toxicities will be evaluated via the ordinal CTCAE standard toxicity grading.

    Measured: Up to 20 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Atezolizumab, Bevacizumab and Capecitabine in people with Metastatic Colorectal Carcinoma and Recurrent Colorectal Carcinoma, run by Academic and Community Cancer Research United at 10 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 17 inclusion and 48 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 23 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 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?

Yes. Results are posted in the registry (first posted 5 Feb 2020). 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?

Progression Free Survival (PFS) (time frame: From randomization to first documentation of disease progression by RECIST v1.1, or death from any cause, assessed up to 20 months). 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 NCT02873195, which also lists 1 linked publication.

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 23 Aug 2024.
