About this study

Official title: A Phase 2 Study of Anti-PD-L1 Antibody (Atezolizumab) in Chondrosarcoma and Clear Cell Sarcoma

This phase II trial studies how well atezolizumab works in treating patients with chondrosarcoma or clear cell sarcoma that is newly diagnosed, cannot be removed by surgery (unresectable), or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVE:

  1. Determine the objective response rates (ORR) using Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1 of atezolizumab in adult (>= 18 years) patients with clear cell sarcoma (CCS) and chondrosarcoma (CS).

SECONDARY OBJECTIVES:

  1. Determine duration of response (DOR) using RECIST v 1.1 and/or change in clinical symptoms (time frame: baseline until disease progression, death, loss to follow-up, initiation of another anti-cancer treatment, withdrawal of consent, or study termination).

II. Measure progression-free survival (PFS) time (time frame: baseline until disease progression, death, loss to follow-up, initiation of another anti-cancer treatment, withdrawal of consent, or study termination).

III. Assess the number of activated CD8+ T cells infiltrating the tumor before and after atezolizumab treatment, and correlate treatment-induced changes with clinical response.

EXPLORATORY OBJECTIVES:

  1. Compare RECIST v 1.1 versus (vs) immune RECIST (iRECIST) in patients with CCS and CS on atezolizumab.

II. Examine changes in PD-1/PD-L1 expression in the tumor microenvironment before and after atezolizumab treatment, and correlate treatment-induced changes with clinical response.

III. Evaluate potential associations between atezolizumab activity and tumor genomic alterations.

OUTLINE:

Patients receive atezolizumab intravenously (IV) over 30-60 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scans and undergo biopsy and collection of blood samples on study.

After completion of study treatment, patients are followed up to 90 days.

What is being measured

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

  1. Objective Response Rates (ORR)

    ORR was measured using the Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1, which involves the following response definitions. Complete Response (CR): disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Stable Disease (SD): neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters while on study. Progressive Disease (PD): at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progressions.

    Measured: Baseline until confirmation of progressive disease or response (complete or partial) as defined by RECIST v1.1, an average of 4 months.

Secondary outcomes (3)

  1. Duration of Response (DOR) or Change in Clinical Symptoms

    Duration of overall response is measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Complete Response (CR): disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. Partial Response (PR): at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. Progression was measured using the Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1 and/or change in clinical symptoms. Progressive Disease (PD): is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progressions.

    Measured: Baseline until disease progression, death, loss to follow-up, initiation of another anti-cancer treatment, withdrawal of consent, or study termination, assessed up to 3 years

  2. Progression-free Survival (PFS) Time

    PFS is the time interval from start of treatment to documented evidence of disease progression, measured by the Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1, or death from any cause, whichever comes first. Progressive Disease (PD): at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progressions.

    Measured: Baseline until disease progression, death, loss to follow-up, initiation of another anti-cancer treatment, withdrawal of consent, or study termination, assessed up to 3 years

  3. Number of Activated Cluster of Differentiation 8 (CD8+) T Cells Infiltrating the Tumor

    Activated CD8+ T cells will be detected by multiplex immunofluorescence assays and will be defined by the expression of T cell receptor (TCR) activation (Zeta chain phosphorylation) or phosphorylated Zap70 (pY493); CD8+ cells present within the tumor section that are positive for these markers will be quantified.

    Measured: Up to 3 years on Cycle 1 Day 1 and Cycle 3 Day 1

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Atezolizumab, Biopsy Procedure and Biospecimen Collection in people with Central Chondrosarcoma, Grade 2 and Central Chondrosarcoma, Grade 3, run by National Cancer Institute (NCI) at 15 sites in 2 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 27 inclusion and 36 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 31 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Canada. 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 23 Oct 2023). 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?

Objective Response Rates (ORR) (time frame: Baseline until confirmation of progressive disease or response (complete or partial) as defined by RECIST v1.1, an average of 4 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 NCT04458922.

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 31 Jul 2026.
