  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Signed informed consent form (ICF) prior to participation in any study-related activities.
  • Male or female patients ≥ 18 years at the time of signing ICF.
  • Ability to comply with the study protocol, in the investigator's judgment.
  • Histologically confirmed TNBC -regardless of PD-L1 status- per American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) criteria based on local testing on the most recent analyzed biopsy. Triple-negative is defined as <1% expression for estrogen receptor (ER) and progesterone receptor (PgR) as determined by immunohistochemistry (IHC), and negative for HER2 (0-1+ by immunohistochemistry [IHC] or 2+ and negative by in situ hybridization [ISH] test).
  • Unresectable locally advanced or metastatic disease documented by computerized tomography (CT) scan or magnetic resonance imaging (MRI) that is not amenable to resection with curative intent.
  • No prior chemotherapy and/or targeted therapy and/or immunotherapy and/or antiangiogenic agent for triple negative MBC. Patients who have received (neo)adjuvant taxane-based chemotherapy and/or immunotherapy and/or an antiangiogenic agent are required to have a disease-free interval (DFI) of at least 12 months after completion of each of these treatments. For (neo)adjuvant non-taxane-based chemotherapy, a DFI of at least 6 months is required.

  • Resolution of all acute toxic effects of prior anti-cancer therapy to grade ≤ 1 as determined by the NCI-CTCAE v.5.0 (except for alopecia, grade ≤ 2 peripheral neuropathy, or other toxicities not considered a safety risk for the patient at investigator's discretion).
  • Evidence of measurable disease or non-measurable disease as per RECIST v.1.1. Patients with only bone lesions are also eligible.
  • Willingness and ability to provide the most recent tumor biopsy since last progression from either metastatic or primary tissues at the time of the inclusion to perform exploratory studies. If not feasible, patient eligibility should be evaluated by a Sponsor's qualified designee. An additional tumor biopsy from either metastatic or primary (only if metastatic biopsies cannot be obtained for inaccessible lesion or subject safety concern) tissues will be collected as soon as possible at disease progression or study termination whenever it is feasible.
  • Note: Patients for whom tumor biopsies cannot be obtained (e.g., inaccessible tumor or safety concern) may submit archived pathological material from either metastatic or primary sites, but the most recent tumor biopsy from the patient should be obtained when available.
  • Note 2: Bone biopsies are only acceptable if performed on bone metastases with associated soft tissue mass, where the biopsy is performed on the soft tissue mass, and a decalcification process is not used. Cytology samples and decalcified bone specimens are unacceptable due to lack of validation studies.

About this study

Official title: Phase II Clinical Trial to Evaluate the Efficacy and Safety of First Line Atezolizumab in Combination With Paclitaxel and Bevacizumab (Avastin®) in Patients With Advanced or Metastatic Triple-negative Breast Cancer

This is a multicenter, open-label, single-arm, phase II clinical trial to evaluate to evaluate the efficacy and safety of first line atezolizumab in combination with paclitaxel and bevacizumab (Avastin®) in patients with advanced or metastatic triple-negative breast cancer (mTNBC)

Read the detailed description

Men and women age ≥ 18 years with previously untreated unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) that is not amenable to resection with curative intent regardless of programmed death-ligand 1 (PD-L1) status.

The number of patients to be included is 100 patients. The primary objective is to evaluate the efficacy -in terms of progression-free survival (PFS)- of first line atezolizumab in combination with paclitaxel and bevacizumab (Avastin®) in patients with unresectable locally advanced or metastatic TNBC.

After signing the ICF and confirmed eligibility, patients will begin treatment on 28 days cycles: Atezolizumab (840 mg) intravenously on days 1 and 15; Paclitaxel (90 mg/m2) via IV infusion on days 1, 8 and 15; Bevacizumab (Avastin® 10mg/kg) intravenously on days 1 and 15.

Patients will receive treatment until disease progression, unacceptable toxicity, death, or discontinuation from the study treatment for any other reason.

Patients discontinuing the study treatment will enter a post- treatment follow-up period until death, withdrawal of consent, patient is lost to follow-up, or study termination.

What is being measured

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

  1. PFS (Progression-free Survival)

    From a clinical point of view, the primary endpoint for this study is the PFS (progression-free survival) defined as the period of time from treatment initiation to the first occurrence of disease progression or death from any cause, whichever occurs first, as determined locally by the investigator using RECIST v.1.1.

    Measured: 24 months

Secondary outcomes (10)

  1. Efficacy (TTR)

    TTR is defined as the time from the treatment initiation to time of the first objective tumor response (tumor shrinkage of ≥30%) observed for patients who achieved a complete response (CR) or partial response (PR).

    Measured: 24 months

  2. Efficacy (ORR)

    Objective response rate (ORR) is defined as the sum of CR and PR relative to the number of patients in the analysis set with measurable disease at baseline.

    Measured: 24 months

  3. Efficacy (CBR)

    Clinical benefit rate (CBR) is defined as the proportion of participants with CR, PR or SD ≥24 weeks relative to the number of patients in the analysis set.

    Measured: 24 months

  4. Efficacy (DoR)

    Duration of response (DoR) is defined as the time from the first documentation of objective tumor response (CR or PR) to the first documentation of disease progression, death due to any cause or treatment discontinuation, whichever occurs first.

    Measured: 24 months

  5. Efficacy (OS)

    Overall survival (OS) is defined as the time from date of treatment initiation to date of death due to any cause. In the absence of confirmation of death, survival time will be censored to last date the participant was known to be alive.

    Measured: 24 months

  6. Efficacy (Best percentage of change of target tumor lesions)

    Best percentage of change from baseline in the size of target tumor lesions is defined as the biggest decrease, or smallest increase if no decrease will be observed.

    Measured: 24 months

  7. Safety AEs and SAEs

    Incidence and severity of adverse events (AEs), serious adverse events (SAEs) according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) v.5.0, including dose reductions, delays, and treatment discontinuations.

    Measured: 24 months

  8. Exploratory objectives (irPFS)

    Immune-related progression-free survival (irPFS) is defined as the period of time from the date of treatment initiation to the date of the first documentation of objective progression of disease (irPD) or death due to any cause in absence of documented irPD.

    Measured: 24 months

  9. Exploratory objectives (irORR)

    Immune-related objective response (irORR) is defined as the proportion of participants with irCR or irPR relative to the number of patients in the analysis set with measurable disease at baseline.

    Measured: 24 months

  10. Exploratory objectives (molecular markers)

    Changes in mutation and copy number in oncogenes, tumor suppressors, and/or other genes associated with disease progression assessed in liquid biopsy.

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Atezolizumab, Paclitaxel and Bevacizumab in people with Metastatic Breast Cancer and Advanced Breast Cancer, run by MedSIR at 26 sites in 5 countries.

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 29 inclusion and 40 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 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 sites in Spain, France, Germany, United Kingdom, Italy. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

PFS (Progression-free Survival) (time frame: 24 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 NCT04408118, which also lists 2 linked publications.

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 Jun 2024.
